PRACTICAL APPROACHES FOR CAPACITY BUILDING FOR TAXONOMY
Note by the Secretariat
1. INTRODUCTION
1. At no time has there been a greater need for taxonomists than now,
as the crises facing biodiversity escalate. Effective habitat conservation,
bioprospecting and the sustainable use of biodiversity on a global basis
all require taxonomic decisions and expertise on a scale not presently
available. In fact, in many countries the number of taxonomists is declining
for a variety of reasons.
2. Decision II/8 of the Second Meeting of the Conference of the Parties
to the Convention on Biological Diversity identified the lack of taxonomists
as a significant impediment to the implementation of the Convention at
the national level.
3. The decision recognised that a sound taxonomic (sometimes called
biosystematic) knowledge base is a prerequisite for environmental assessment,
ecological research, the conservation of biological diversity, and managing
biological resources within a framework of sustainable development and
fair and equitable sharing of those resources. It called for taxonomy to
be directed towards practical ends, including bioprospecting and ecological
research on the conservation and sustainable use of biological diversity
and its components.
4. Taxonomy is the practice of naming life forms and arranging them
in classifications that reflect patterns of relationships. Taxonomy forms
part of the science of systematics, which deals with the organisation,
history and evolution of life, its diversification and distribution in
space and time (Novacek 1992). It is the tool by which the components of
biological diversity at the species level are identified and enumerated,
and it therefore provides the basic knowledge underpinning efforts to conserve
biological diversity, optimise the use of biological resources in a sustainable
way, and enhance the quality of life in diverse human societies.
5. Classical examples of the practical value of taxonomy include the
exhaustive taxonomic research on African freshwater snails and mosquitoes
that provided the foundation for biological and medical research into bilharzia
and malaria, and the development of high-yield, hardy strains of wheat
based on the detailed exploration and study of the taxonomy and properties
of wild wheat forms from around the globe. More examples, perhaps less
well known but equally important, are presented in Annex 1.
6. Decision II/5 specifically requested that the SBSTTA, at its second
meeting, address the issue of the lack of taxonomists needed for the national
implementation of the Convention and to advise the Conference of the Parties
at its third meeting on ways and means to overcome this problem, taking
into account existing studies and ongoing initiatives while adopting a
more practical direction of taxonomy which is linked to bio-prospecting
and ecological research or conservation and sustainable use of biological
diversity and its components. In order to assist the SBSTTA in its consideration
of this issue, the Secretariat has prepared this document which reviews
the current status of taxonomic capacity, particularly in developing countries,
considers how taxonomic capacity might be developed and contains a number
of options to address the needs of the Convention and its Parties.
2. BACKGROUND TO THE PROBLEM
2.1 The Discipline of Taxonomy
7. Taxonomists are trained biological scientists who specialise
in the identification, formal description, classification, and naming of
plants, animals and microorganisms.
8. Taxonomy underlies our understanding of biodiversity because it
addresses fundamental questions such as the kinds of organisms that exist,
their number, how they are related to each other, where they occur, and
then allocates names to them in a systematic manner. Without this basic
knowledge of the facts of biodiversity, its conservation cannot proceed
in an informed, and therefore sustainable, manner. In particular, by allocating
universally recognised names to organisms, taxonomy provides a common language
for communication about biodiversity.
9. The discipline of taxonomy is based on universal principles developed
over the 270 years that have passed since the pioneering work of Carolus
Linnaeus, the Swedish naturalist. The basis of these taxonomic principles
is a recognition of structural resemblances among organisms, so that if
organisms have similar structures, they may be regarded as members of the
same classification group, that is, they are closely related to each other,
and therefore their naming should reflect this close relationship.
10. Intrinsic to the discipline of taxonomy is the recognition that
related organisms may occur in widely disparate parts of the earth. This
means that it is often not possible to carry out taxonomic studies of the
biota of a
particular region or country in isolation; these studies must be placed
in their global context by comparative analysis.
11. The work of taxonomists is based on the study of the characteristics
of the particular group of organisms that define the group (or taxon) and
differentiate it from other taxa. In order to do this, it is necessary
to have adequate samples of the plants or animals being described, and
likewise specimens of the related taxa to which they are being compared.
Samples are collected from living specimens occurring in their natural
habitat, preserved as specimens in accordance with standardised procedures,
and kept in herbaria (in the case of plant specimens) and museums or fauna
collections (in the case of animal specimens). Detailed records of each
specimen are essential.
12. When a taxon (e.g., a species or genus) is defined and described,
the description is related to a particular specimen, known as the type
specimen, whose location in a particular herbarium or museum is clearly
identified. It is essential for the continuing and orderly application
of taxonomic principles that type specimens, together with suites of specimens
of related organisms, are preserved in perpetuity, to provide comparative
information that can be used to classify and name new species as they are
discovered.
13. The discipline of taxonomy has developed standardised rules and
procedures that are embodied in various internationally accepted codes,
such as the International Code of Botanical Nomenclature and the International
Code of Zoological Nomenclature. International bodies of scientists develop
and maintain these codes, which ensures that taxonomic research maintains
internal consistency and can be applied with confidence to any group of
organisms wherever it is found on earth. The codes are not quite identical,
and thus there are some differences in approach between botanical, zoological
and microbial codes.
14. The results of taxonomic research, like other scientific research,
are published in internationally accepted journals through established
procedures, including peer review. Subsequently, the results are brought
together in publications (including electronic media) such as handbooks,
catalogues and floras, usually on a regional or national basis.
15. Taxonomists generally gain their qualifications by undertaking
studies in biology at a university and then undertaking postgraduate or
specialist research in taxonomy. In gaining their taxonomic qualifications
they learn the skills of collecting, identifying, describing and naming,
classifying, and elucidating the distribution of the groups of plants,
animals or microorganisms in which they intend to specialise, all within
the formal framework of the Codes and within the accepted scientific culture
of precedence, peer review, and publication.
16. Taxonomists are predominantly employed in herbaria, museums, government
agencies such as departments of conservation and agriculture, and in universities.
Thus, in most countries the employment of taxonomists is heavily dependent
on the government funding that supports such institutions.
2.2 The Lack of Taxonomic Capacity
17. The task confronting taxonomists as they attempt to provide
an inventory of global biodiversity is enormous. Recent estimates of the
total number of species on Earth range between 5 million and 100 million.
Of these, little more than 1.5 million have been formally described and
named in a taxonomic sense. Moreover, the geographic and ecological coverage
of this taxonomic knowledge is very uneven globally.
18. At this very time when the need for a taxonomic stocktaking of
the Earth's biodiversity is becoming increasingly urgent, the community
of taxonomic experts is aging and declining in number, and the resources
committed to the management of taxonomic collections is diminishing (Cotterill
1995). This lack of taxonomists is a critical problem that needs to be
addressed on a global scale.
19. In the last century and the first half of this century public interest
in and national capacity for taxonomic work were high in Europe and North
America, but the advent of new subdisciplines of biology in the latter
half of the 20th century has tended to siphon off researchers who might
otherwise have become taxonomists. This has led to a decline in the training
and recruitment of young researchers in this field in industrialised countries.
20. In developing countries, formal knowledge about biodiversity tended
in the past to be generated by taxonomists from industrialised countries.
Their work was usually funded from the researcher's home country or by
international bodies, and the studies were not necessarily aligned with
the "host" country's needs. Specimens collected were, as a rule,
deposited in major European or North American collections, often with no
attempt to establish collections in the countries of origin, or to lodge
voucher specimens there for identification purposes. This is true also
for countries such as Australia, which in its colonial era, lost many important
type specimens to European collections.
21. Because of this historical background, many of these "host"
countries have not developed the requisite level of expertise, infrastructure
and employment opportunities required to address urgent taxonomic issues
locally, although there was, of course, a degree of skills transfer, particularly
in field-work methods and basic identification.
22. Even where museums and herbaria have been established to provide
for the safe storage of specimens and the infrastructure for research and
information retrieval, many of these institutions now have inadequate resources
even to maintain their collections in an active, accessible form, let alone
to expand and develop their great potential to contribute to the aims of
the Convention and to national, regional and local objectives.
23. Concurrent with this decline in taxonomic capacity, technological
advances have aided access to remote habitats (for example, deep oceans),
thereby revealing previously unknown biological resources and creating
an even greater need for taxonomic effort.
24. In addition, the Convention has focused attention on the urgent
need for inventories of biological resources, including generalised surveys
to assess conservation status, targeted surveys to explore pharmaceutical
resources or new genetic resources for primary industry, and the rapid
assessment and monitoring of habitats. This has created a demand for taxonomic
capacity to be directed towards functional aims, often with an emphasis
on quick results. However, the results of such surveys need to be presented
within the framework of the accepted nomenclature developed by traditional
taxonomic methods.
25. These various approaches to the acquisition of knowledge about
biodiversity require a range of taxonomic skills to be available in each
country or region. This in turn creates a demand for increasing numbers
of taxonomists, both fully qualified experts and lesser qualified parataxonomists.
The optimum blend of skills required in any particular regional or national
setting also needs to be addressed.
26. Public awareness of the immediate and future values to human welfare
of biodiversity conservation and land management, and the role of taxonomy
in their achievement, is critical to their success. Educational programs
are needed to achieve this awareness.
27. In the industrialised world, public awareness of the need to conserve
and manage threatened and vulnerable aspects of biota and generally to
reverse environmental degradation and misuse has increased dramatically
over the past two or three decades. There has been a failure, however,
to develop any political, corporate or general public understanding and
appreciation of the role of taxonomy as part of this new awareness.
28. In some developing countries political awareness of biodiversity
conservation and management may be largely centred on nature-based tourism
and the economic potential of genetic resources, which are as yet largely
unknown. General awareness amongst the public of the need to conserve and
manage local and regional ecosystems may be low, although local knowledge
among indigenous peoples about plants and animals is high, and often more
detailed than formal taxonomy.
3. STATUS AND TRENDS
3.1 The Existing Knowledge Base
29. The expansion of taxonomic capacity in developed countries
must build on existing knowledge accumulated over decades and centuries.
Most if not all developed countries hold, or are currently building, national
collections within their governmental structure. Many also have significant
collections established outside the official framework. Such collections,
often private and brought together over many years and even generations,
may be limited in taxonomic scope but highly valuable from both a historical
point of view and as a part of the existing national knowledge base (Cotterill
1995). It is important to locate, recognise, and ensure the long-term safety
of important collections of this kind.
30. For many developing countries, lacking such institutions within
their own boundaries, the primary sources of information about their own
biodiversity are the long-established collections in the developed countries
and the widely scattered scientific literature. They need to be able to
access these sources, but are inhibited from doing so by the variety of
formats and institutions and by the fact that electronic access is inadequately
developed.
31. There is therefore an urgent need for the dissemination of existing
taxonomic knowledge back to the countries of origin, in a consolidated
form targeted to immediate, nationally determined needs.
32. The existing taxonomic knowledge base differs significantly between
continents, regions and nations, and between groups of organisms. Charismatic
groups like birds and mammals, and, to a somewhat lesser degree, groups
such as flowering plants and trees, snakes, butterflies and dragonflies,
are quite well known globally, but tools for identification in the field
(locally or regionally) are often not available.
33. Knowledge about the diversity of most invertebrates, lower plants,
fungi and microorganisms in terrestrial, freshwater and marine habitats
range from good in some groups in developed countries to poor and often
minimal in most parts of the world. On a conservative estimate of global
biodiversity (e.g., 10 million species) about 15 percent of species (1.5
million) are known, approximately two-thirds of which are insects.
34. Developing countries generally do not have large reference collections
of plants and animals for help in identification and to provide the basis
for research relevant to their national needs. While most countries now
require representative material from field collecting to be deposited as
types or voucher specimens in designated national repositories, reference
material from taxonomic studies carried out over the past two centuries
is mostly deposited in overseas collections.
35. The repatriation of such physical collections, as opposed to supplying
database information, is unlikely to be adopted as a means of boosting
taxonomic capacity in developing countries. Development of nationally or
regionally relevant reference collections should be undertaken as a combination
of local field work and specific "packages" of authoritative
voucher specimens collaboratively compiled from large, established collections
in the industrialised world. The critical issue for such reference collections
is the correct (authoritative) identification of species.
36. The trend in developed countries is increasingly to prioritise
funding for taxonomic research on groups that are believed to be either
of significance in the maintenance of ecosystem health, or that are of
particular interest to sustainable primary industry production or pharmaceutical
surveying. Nevertheless, they also maintain, to a greater or lesser degree,
support for continued taxonomic studies across the entire range of living
organisms in order to provide the broad knowledge base essential to organise
and underpin research in all fields of biology.
3.2 Existing Taxonomic Capacity
37. Taxonomic capacity building should be based on a nationally
or regionally assessed balance between skills, expertise, the collection
and research infrastructure necessary for identifying and documenting targeted
groups of plants, animals and microorganisms, as well as medium- to long-term
requirements for accelerating broader based inventories and understanding
of biological diversity. The experiences of the developed countries provide
lessons, both positive and negative, for other countries.
3.2.1 Human resources
38. Human resources currently available for taxonomy are summarised
in the Global Biodiversity Assessment. There may be 20,000 to 30,000
biological taxonomists (biosystematists) worldwide. Very few of these are
believed to be engaged full-time in systematic research. Around 7000 are
actively publishing new descriptions of species in journals. The great
majority of systematists work in North America and Europe, although not
necessarily on species or groups of species from those regions. Fewer than
10% of taxonomists are resident in the moist tropics, which hold far more
than 50% of global non-marine biodiversity. Moreover, effort is very unequally
distributed amongst different taxonomic groups, with a large percentage
of taxonomists engaged in studying groups that are among the best documented.
For example, in Australia it is estimated that there are 17 species of
higher vertebrate for each taxonomist concerned with this group, but 840
insects and spiders for each taxonomist concerned with these groups. Globally,
and taking into account estimated rather than described species, the discrepancy
varies from 370 or so plants per plant taxonomist to perhaps 5000 viruses
per virus taxonomist.
39. The lack of jobs and lack of training have interacted over recent
decades to produce a downward spiral in the numbers of taxonomists and
in the volume of taxonomic work being undertaken in the developed world.
This trend reduces the ability of the international taxonomic community
to support capacity building in developing countries. A way of cutting
this nexus needs to be found.
40. To achieve this, the importance of taxonomic work, not only from
the point of view of conservation, but from an economic perspective as
well, must be emphasised. Such emphasis is particularly important in the
emerging fields of bioprospecting and sustainable use of natural resources.
The vast majority of taxonomists are currently employed directly or indirectly
by governments, generally in museums, herbaria, government departments
or in tertiary education institutions. Future job growth, if it is to occur,
will largely be in national or provincial governments, although corporate
sponsorships for taxonomists under the umbrella of environmentally sustainable
development, and employment or funding of taxonomists by primary and pharmaceutical
industries provide potential opportunities. International funding activities,
such as, inter alia, the UK Darwin initiative could play a key role
here.
41. Many developed countries with a long tradition of tenured positions
in taxonomy-oriented institutions are now tending to offer shorter term
contracts of 3 to 5 years when filling vacancies, and are increasingly
expecting their taxonomic staff to attract funds for research through consultancy
projects with external bodies, often with a less-than-rigorous taxonomic
focus. To acquire high-level taxonomic expertise takes many years, and
involves research projects with time-frames much greater than those typically
supported by external consultancies. The new trend towards shorter-term
engagements will inevitably aggravate the problems faced by taxonomy in
general, not the least by eroding the recruitment base by undervaluing
the nature and importance of taxonomy and diminishing the possibility of
creating a long-term career in the field.
42. Whilst developed nations will need to reassess this approach before
a critical loss of high-level expertise becomes apparent, it is urgently
important that taxonomic capacity in developing countries be built on a
solid foundation of tenured positions coupled with attractive academic
as well as technical career structures that encourage staff to stay in
front-line research. With such a core of tenured taxonomists and technical
staff, taxonomic training, job opportunities, taxonomic work and collection
development can be enhanced by providing short- to medium-term jobs from
external funding (research grants, project-based funds).
3.2.2. Taxonomic infrastructure
Collections and research
43. Taxonomic work requires it own infrastructure, the most important
parts of which are well-maintained, secure, representative collections,
adequate library facilities, and laboratory/office space equipped with
standard research tools such as microscopes and personal computers. The
funding outlook for the collections in particular must be permanent, as
taxonomy is heavily dependent on historical precedents and the ability
to consult previously reported and unreported material. Biological collections
are a significant part of the national and international heritage. Whatever
the administrative arrangements for their operation, they must be covered
by statutory protection against mismanagement or uncontrolled disposals
or dispersal. At the operational level, taxonomy cannot function on a stop-start
basis; expertise cannot be developed or maintained and it becomes unattractive
to enter this field of research.
44. Compared with most other branches of natural science, the capital
costs of taxonomic infrastructure facilities are modest, as are the costs
of day-to-day maintenance and research projects. Despite this, many national
governments in developed countries have increasingly, over the past few
decades, starved taxonomic institutions of capital and operational funds
(Idema 1993), to the point where many national collections are barely surviving,
research areas are being reduced or closed down, and major parts of internationally
significant collections are rendered inaccessible by being "mothballed".
45. Nationally and regionally, developing countries have the opportunity
to lead the way in a revival of biological collections and the biosystematic
research that depends on them by recognising their fundamental importance
and placing taxonomic capacity building as a high national priority in
the pursuit of sustainable development and conservation.
Field work
46. The development of biological collections as major national
facilities for public inquiry and for current and future taxonomic research
relies almost exclusively on field collecting and biosystematic field studies,
primarily by the institution's own staff, but importantly also through
the acquisition of material collected by others for related purposes.
47. Field work requires its own infrastructure in the form of transportation
means, specialised collecting equipment and, often, camping facilities
adequate for keeping samples and equipment (and people) safe under adverse
conditions. Effective and efficient field collecting requires training
and experience, not only in operating and maintaining specialised equipment,
but also in general biological knowledge (natural history, habitats, ecology)
in order to optimise field time.
48. Properly targeted and supervised, the field collecting of specimens
and associated biological and environmental data is an area particularly
well suited to the enhancement of the responsibilities and expertise of
collection managers and parataxonomists. It is a fertile training ground
for the development of taxonomic expertise and recruitment to a taxonomic
research career.
49. While developed countries now possess highly sophisticated equipment
to undertake biological collecting in the most inaccessible and inhospitable
environments on the globe, the general trend is to significantly reduce
operational funds for the basic field work necessary for standard collection-based
taxonomic research, which is relatively low in cost and often locally based.
Consequently, the acquisition of specimens becomes reliant on participating
in external consultancies that are frequently broad-based surveys with
limited time-frames and that are not targeted to meet the researcher's
requirements.
Dissemination
50. Traditionally, new taxonomic knowledge has been disseminated
in scientific journals for the consumption of fellow taxonomists. This
knowledge base was, and still is, largely inaccessible to the many users
who now require identification of and correct names for plants and animals,
as well as access to spatial data. Efforts to collate taxonomic knowledge
for distribution on a global scale either in hard copy or electronically
are in train for many groups of plants, animals and microorganisms.
51. Such publications and databases are unlikely to be of significant
help to developing countries in the short to medium term because of the
long term nature of most projects, and because they do not target the diverse
needs of individual countries or local requirements. In the longer term,
they will have a major impact on all taxonomic work, and developing nations
will have a significant role in contributing to the global databases as
one result of their taxonomic efforts.
52. New taxonomic knowledge must continue to be reported in international
scientific journals to ensure the appropriate recognition of national efforts.
It is important, however, that taxonomic output also focus on other activities,
including the preparation of fauna and flora catalogues, databasing of
and user access to biodiversity information, and identification tools for
targeted groups of plants and animals in order to further facilitate local
or regional ecological studies, conservation efforts and responsible bioprospecting.
It should be recognised also that identification tools for the more conspicuous
groups of plants and animals in a well circumscribed area have great appeal
for nature tourists and amateur naturalists, who can contribute significantly
to local economies by visiting those areas.
Public education
53. Probably the main reason for the decline in resources for taxonomic
research and the maintenance and development of biological collections
in the industrialised world over the past several decades is the failure
of taxonomists to communicate the relevance and importance of their science
to the public in terms of community concerns about local and global environmental
issues. Similarly, many taxonomists and their institutions have been reluctant
to adjust research and outputs to user needs and expectations. Even the
non-government conservation organisations and their large numbers of supporters
appear to be unaware of the crucial role of taxonomy.
54. Taxonomy as a discipline has relied for too long on the public
image it developed last century, without taking up the competitive challenge
for recognition and access to limited resources from technologically new
disciplines in the natural sciences. There is a clear movement among biosystematists
in the developed countries to try and reverse this trend, but the community
impact, and hence political impact, so far is very limited.
55. In building taxonomic capacity, developing countries should embrace
these lessons in order to ensure a high degree of public acceptance of
the role and benefits of biological collections and biosystematic research,
and to promote a sense of community pride in and responsibility for biological
diversity as a source for improved human welfare and as a national heritage.
Two issues are of particular importance in publicising this message: education
targeted to relevant local problems and conditions, and the strength of
supportive messages sent out by the highest levels of government.
56. It is important that community education focus on the less charismatic
components of biodiversity -- invertebrates, lower plants and microorganisms
-- that comprise the vast majority of biological species, and thus genetic
resources, responsible for developing and maintaining ecosystem integrity
with its attendant socio-economic benefits. Only with such a focus may
the so-called "megafaunal bias" (Platnick 1991) be avoided, which
sees vast resources spent on a few large species without adding to the
broad knowledge base required for conservation and sustainable development.
Pragmatically, a "piggy-back" approach may be effective in letting
the few pull the many along, and in explaining the complex links between
the few, the many and the ecosystems in which they interact.
57. In building up taxonomic capacity in developing countries, it is
critical that governments recognise and support: the links between national,
regional and local needs; well-targeted field collecting; establishing
and maintaining biological collections; taxonomic research; the timely
and appropriate dissemination of research results to users; and public
education about the role and benefits of taxonomy as a national effort.
3.3 Training new taxonomists
58. Universities and other tertiary institutions are not teaching
taxonomy (or other whole-organism studies such as morphology) to the same
extent as in past years. New "cutting edge" disciplines such
as molecular biology have displaced them in crowded curricula. Increasingly,
students are being graduated as narrow specialists in the infrastructure
of plants and animals, but with little understanding of the whole organism
or of the phylogenetic and taxonomic relations of the taxa on a broad scale.
59. The result is that the world's pool of trained taxonomists is shrinking,
and aging, while there is insufficient recruitment of young scientists
to replace the existing workers. This problem is strongly linked to a second
problem: the lack of jobs for taxonomists. There is a perception that taxonomy
is "old-fashioned science" and that there are few jobs available
for taxonomists. This reinforces the trend towards diminution of training.
60. Concurrently, the increasing concern with threats to biodiversity
worldwide has highlighted the enormous gaps in taxonomic knowledge of the
world's flora and fauna. While there is a well-founded perception that
organisms are under threat, the size of the threat and the numbers of taxa
involved can only be guessed at so long as the cataloguing of taxa and
their distribution remains incomplete, or in some cases, barely begun.
Attempts at management and survey that are not backed by sound taxonomy
will inevitably be flawed.
61. This aspect of the problem can only be addressed by educating the
educators, and by demonstrating that taxonomy has a central role to play
in natural science. The generation of jobs for taxonomists will automatically
drive a demand for training. At the same time the role of taxonomists as
the driving force behind large, important and prestigious projects needs
more publicity.
3.4 Monographic Treatment versus Inventory versus Rapid Assessment
62. Over the last fifty years, public and political environmental
imperatives have changed dramatically at the local as well as global levels
(deforestation, soil degradation, pollution of fresh water sources, utilisation
of genetic resources, global biodiversity crisis, and the greenhouse effect
are just some of the major contemporary concerns). Apart from their direct
impact on human welfare, all these environmental problem areas have serious
implications for the survival of local and regional species diversity,
which is essential in maintaining healthy ecosystems and providing sustainable
bases for agriculture and for the utilisation of biological resources.
63. All conservation planning and management, and efforts to remedy
past mismanagement and restore economically and environmentally significant
habitats, require input from, and underpinning by, biosystematic studies.
The demands for taxonomic knowledge and the ability to confidently identify
organisms is steadily increasing, a situation that is in stark contrast
to the decline in numbers of trained taxonomists.
64. In order to accelerate environmental research without having to
wait for results from traditional taxonomy, which is perceived to be slow
to deliver because it is based on monographic treatments, new methodologies
have been developed for assessing biodiversity. These include inventories,
surveys, rapid biodiversity assessment, monitoring, and the use of indicator
species. While these techniques are designed to provide specific answers
to specific questions within a short time-frame, they nevertheless rely
on a taxonomic underpinning and using identification skills obtained through
taxonomic training. Thus, traditional taxonomy cannot be bypassed. Rather,
in seeking to understand the particular nature of the biodiversity of a
nation or a region and the associated management problems and socio-economic
potential, all these methods will have to be employed.
65. Inventories and surveys are crucial first steps in making a census
of poorly known habitats (Cotterill 1995). They rely heavily on field work
and medium-level identification skills, the realm of parataxonomists. They
produce important specimen materials and associated distributional and
biological data that flow back into biological collections as voucher collections
for subsequent verification of identification and that can contribute to
the data base for expert taxonomic research.
66. Rapid-assessment methods and sampling for indicator species are
designed to monitor selected biotopes of critical value; for example, river
health. Base-line studies of pristine or near pristine biotopes are required
against which "trouble spots" are monitored. Medium-levels identification
skills are necessary. Collaboration between staff with parataxonomic skills,
hydrologists and statisticians is necessary. Monitoring sites would normally
be selected on the basis of inventories or surveys of relevant ecosystems.
67. Monographic taxonomic research deals with all species in a particular
taxonomic group within a specified region. Such studies are crucial in
bringing results from inventories and surveys forward to a new level of
taxonomic knowledge and in developing identification tools. This is particularly
important for ecological research, managing genetic resources, determining
agricultural and forestry pests, and assessing potential biological-control
agents.
68. In building taxonomic capacity in developing countries, nations
or consortia need to assess and prioritise job requirements, training needs
and infrastructure against the mix of methods that will be employed. This
is a dynamic process where increased knowledge derived from one method
will fuel demands for increased input from other taxonomic fields. For
example, the need to progressively refine the level of identification in
inventories will place increasing demands on specialist taxonomists for
the monographic research and production of inclusive identification tools.
3.5 Existing Models for Developing Taxonomic Capacity and Knowledge
69. Programs for taxonomic capacity building, enhancing the taxonomic
knowledge base and developing electronically accessible databases containing
consolidated information are initiated at many levels, ranging from local
counties and individual institutions through provincial, national, and
broader regional efforts, to global initiatives. They reflect a range of
different objectives and time-frames. There is an unrealised major potential
for enhancing the flow of knowledge between and among these various programs,
and for reducing the duplication of effort.
70. Examples of national and international mechanisms and program initiatives
in support of taxonomy are presented below. International programs provide
regional or global structures that link national efforts to wider networks.
National models reflect specific needs, priorities and capacities. They
may provide a model for adoption, either directly or with modification,
by developing countries that are setting out to build up their taxonomic
capacity.
3.5.1 National models
Government appropriation
71. General government funding for taxonomic research and collections:
Capital, salary and basic infrastructure costs for taxonomic research and
training normally are funded by governments through budget appropriation
(museums, herbaria, tertiary institutions, other government agencies).
The issue of concern with this model is that in many cases financial support
is stagnating or declining, which impacts adversely on collection maintenance
and development (e.g., security, accessibility, transfer of specimen data
to electronic format), the renewal of equipment and research tools, training
and recruitment, and the capacity to undertake field-based studies.
72. Increasingly, the trend is for governments to expect researchers
and their institutions to obtain operational funds for research projects,
including equipment and technical assistance, from external sources.
National research agencies
73. Government funding for autonomous or semi-autonomous research
agencies is the most commonly applied model for competitive research support.
National research agencies are frequently subdivided into autonomous branches
(e.g., medicine, natural sciences, arts). Research agencies set broad priorities
and funding policies.
74. In many countries, research agencies are the main or only source
of external funding for taxonomic research. The advantage of the research-agency
model is that agencies have the financial capacity to provide the more
expensive taxonomic research tools (e.g., electron microscopes, large collaborative
projects with heavy field logistic requirements). The disadvantage of this
model is that taxonomic research is in direct competition with projects
from a wide range of other research fields. This is particularly detrimental
in an intellectual environment where taxonomy is not seen as front-line
research. In addition, the direction of taxonomic research funded through
the research-agency model, notwithstanding the quality of individual projects,
can becomes unfocussed due to the generally very broad priorities.
75. If the research-agency model is used to drive capacity building
in taxonomy within its broader charter, funding for 3- to 5-year periods
should be earmarked and perhaps placed under a separate advisory subcommittee
with responsibilities for setting priorities and vetting funding proposals.
Primary industry corporations and agencies
76. Primary industry bodies concerned with, for example, agriculture,
horticulture, livestock and forestry, frequently dispense funds for research
and development (R&D). Funds for R&D will often derive from a combination
of a levy on the constituency supplemented by government appropriation.
Major funding issues include the exploration of new sustainable resources,
the development of new genetic strains, and pest control. These areas require
a solid taxonomic foundation for setting funding priorities.
77. In general, primary industry relies on other organisations and
funding sources to provide the taxonomic foundation they require as end
users. The end users are thus not in control of priority setting. There
is, however, an increasing understanding of the need for primary industry
to set its own priorities and allocate funding for taxonomic research (normally
on contract to specialist organisations) to underpin their required R&D.
78. This trend should be strongly encouraged in industrialised as well
as developing countries, as it has significant potential for increasing
and focusing taxonomic capacity in areas of immediate economic importance.
Targeted funding
79. Funding bodies targeted more or less specifically towards taxonomic
research and inventories are not common, but several models have emerged
in recent decades. Representative examples are outlined below.
The Government-program approach
ABRS
80. The Australian Biological Resources Study (ABRS) was established
by the Australian Federal Government in 1973 in recognition of the inadequate
knowledge about Australia's plants and animals and where they occur. The
aim of the program is "To provide the underlying taxonomic knowledge
necessary for the conservation and sustainable use of Australia's biodiversity".
The ABRS is part of the Australian Nature Conservation Agency and the program
is guided by an Advisory Committee comprising leading taxonomists, who
are appointed to the committee by the Minister for the Environment. The
ABRS employs three key strategies:
(a) A Participatory Program of competitive
grants for taxonomic and biogeographical research, which includes a strong
focus on attracting and training young taxonomists. The Advisory Committee
publicises annual priorities for funding.
(b) A publishing program for a major book series
on Australia's plants, animals and microorganisms on a continental scale
(Flora of Australia, Algae of Australia, Fungi of Australia, Fauna of Australia,
Zoological Catalogue of Australia). There is strong feed back to the publishing
program from the research grant program.
(c) Liaison with and coordination between Australian
and overseas taxonomists and their institutions, primarily museums, herbaria,
other large biological collections and biological departments in universities.
ABRS also establishes links with regional and global initiatives in taxonomy.
81. Since museums and herbaria in Australia are funded primarily by
individual state governments, ABRS has provided an essential focus for
coordination and for setting priorities for taxonomic research at a national
level. The result has been a significantly increased collaboration in the
field of taxonomy, and an avenue for bringing concerns about collection
maintenance, development, and electronic access on a national scale to
the attention of the federal government in a consolidated way. In addition,
a substantial amount of skills transfer has been achieved through the involvement
on research grants of overseas experts.
82. ABRS employs 20 staff, mainly professional taxonomists working
as scientific editors, and including a small secretariat for grant administration.
The annual research-grant budget is currently just under A$2 million, which
supports 68 research projects. Although a federal agency, ABRS works closely
with state agencies to deliver a nationally focused program.
83. The strength of the ABRS Program is its constantly maintained focus
on taxonomy, on distribution in monographic form rather than on local inventory
type lists of names, its direct access to Government, and its strong links
with and recognition by the taxonomic community.
CONABIO
84. Comision Nacional para el Conocimiento y Uso de la Biodiversidad
(CONABIO) was established as a ministerial commission in 1992 by the Mexican
government and started operations late in 1993. The priority area is to
support the development of taxonomic checklists and databases on Mexico's
biodiversity, but CONABIO's charter is broad and includes issues such as
charting indigenous use and knowledge of biodiversity, databasing information
about Mexican biodiversity stored in collections outside Mexico, and continually
educating the population through the media (Nature 368).
85. Government funding is placed in a trust administered by the national
development bank. This unique mechanism provides a buffer against political
vagaries and allows considerable accounting flexibility, including the
acceptance of donations.
86. The high-level government support (CONABIO's president is the president
of Mexico) sends a very strong message to the entire population about the
government's commitment to exploring, conserving and sustainably using
Mexico's biodiversity.
The private, non-profit approach
INBio
87. The Costa Rican Instituto Nacional de Biodiversidad (INBio) was
established in 1989 (Gamez et al. 1993). INBio is an autonomous, non-profit
private institution with strong links to organisations involved with its
creation (government ministries, the National Museum, universities, the
National Scientific Research Council, non-government organisations).
88. INBio's key objectives are: to carry out a total inventory of Costa
Rica's biodiversity by the year 2003; enhance the collection infrastructure
through integrating diverse collections; centralise (including "repatriation"
of data and information) and distribute information on Costa Rica's biodiversity;
and increase local awareness of the importance of biodiversity conservation
and sustainable-use issues.
89. INBio employs around one hundred administrative and scientific-technical
staff, partly at headquarters and partly at 29 Biodiversity Offices situated
in and around national Conservation Areas.
90. Capital works, infrastructure, training and detailed planning required
over the first years were funded by private foundations and donors from
around the world, by the Costa Rican government, and by external government
bodies concerned with aid programs in developing countries. Following this
initial phase, INBio must become self-supporting. Funds required over the
next decade to undertake the National Biodiversity Inventory and to ensure
the permanent maintenance and development of the biodiversity collections
are estimated at $50 million.
3.5.2 Global and Regional Initiatives in Taxonomy
91. Following Rio and the adoption of the Convention on Biological
Diversity and Agenda 21, a number of international programs or national
programs with international scope were initiated that implicitly or explicitly
aim, in whole or in part, at strengthening global taxonomic capacity, restoring
the role of and support for biological collections in the biodiversity
equation, and developing comprehensive regional or global taxonomic publications
and databases summarising current knowledge about the planet's biological
diversity. Examples are given below.
Initiatives that include taxonomic capacity building in their goals
GEF
92. The Global Environmental Facility (GEF) was developed by the
international community, concurrently with the completion of the Convention
on Biological Diversity and Agenda 21, as a global fund for biodiversity
conservation and other environmental priorities.
93. As a recent example of the GEF providing substantial support for
taxonomic infrastructure capacity building, the Biodiversity Collections
Project for Indonesia must be highlighted. The project aims, over the next
five years, to build the institutional capacity of the national herbarium
and the national zoological museum to inventory, monitor and study Indonesia's
biodiversity. This joint Indonesian-GEF funded project has a strong focus
on reviving, restoring to safe curatorial practice and developing the existing
large and very valuable biological collections in recognition of their
crucial role in understanding the nation's biodiversity. The project includes
the building of a national biodiversity information system (Townsend 1995).
94. The GEF may apply such funding mechanisms as project trust funds.
If the GEF were to get involved in national or regional taxonomic capacity
building programs, such trusts would allow the orderly development and
implementation of major capital infrastructure issues or operational aspects.
They would also provide a hedge against currency devaluations and the vagaries
of politics, and would provide the basis for long-term funding security.
WCCR
95. The World Council on Collections Resources (WCCR) was founded
in 1992 as an outcome of the first World Congress on the Preservation and
Conservation of Natural History Collections in Madrid in 1992. Its aims
are to facilitate the development of research-quality natural history collections
in developing countries, provide public education about the value of these
collections, and promote access to collection-based information. The WCCR
has already been asked to help secure funding for a new natural history
museum in Vietnam.
BioNet
96. The Biological Network (BioNet) was established in 1994 by
agreement between a large number of developed and developing countries.
Funding has been negotiated with, among others, the World Bank and major
international development banks. The aims of BioNet are to support taxonomy,
identification, training, collections and research infrastructure, primarily
in developing countries, in regional frameworks. Currently the emphasis
is on microorganisms and insects, but other high-priority biodiversity
groups are given consideration. BioNet has a small international secretariat
and locally organised networks of countries called "loops". Loops
in the following regions have been or are in the process of being established:
the Caribbean, South Africa, South East Asia, South Pacific Island Countries.
Initiatives that aim at surveys, inventories and databasing
BS&I
97. The Biotic Surveys & Inventories Program (BS&I) of
the United States National Science Foundation was established in 1991.
The program supports research aimed at recording and documenting the diversity
of life on Earth based on field collecting or inventories in broad bio-regions.
It also supports inventories of existing collections, and the development
and dissemination of taxonomic databases. The BS&I has funded projects
on plants, animals, fungi and microorganisms worldwide: in North and South
America, Asia, Pacific, and Madagascar , for example (Lane 1995).
Initiatives that aim at presenting a global overview of existing knowledge
ETI
98. The Expert Centre for Taxonomic Identification (ETI) was started
in 1991. A non-profit organisation associated with the University of Amsterdam,
it is funded by the Dutch government, the University of Amsterdam and UNESCO.
ETI aims to concentrate, preserve and distribute taxonomic and biological
knowledge worldwide by aid of modern computer technology, to support research,
inventories, monitoring and conservation efforts. On-line access to ETI's
databases and the distribution of tailored subsets on CD-ROM are the dissemination
means. ETI envisages that data and information will be made available in
a highly interactive, multimedia form. ETI has produced several CDs, including
Birds of Europe, Holothurians of Northern Australia, and Marine Turbellarians
of the World. A UNESCO-IOC "Register of Marine Organisms" project
is currently under way in collaboration with ETI. The Register project
is associated with the "Species 2000: Indexing the World's Known
Species" conceptual framework (IUBS-ICSU-IUMS).
99. Species 2000: Indexing the World's known species is a new programme
launched by the IUBS at its General Assembly in September 1994. The objective
of the programme is to enumerate "all known species of plants, animals,
fungi, and microbes on Earth". It hopes, ultimately, to establish
a meta database of standards and working taxons for all groups of organisms
which will be accessible electronically. Implementation of Species 2000
will involve the establishment of a global federation of existing taxonomic
databases. These master species databases will provide the validated names.
Financing for this programmes is yet to be secured but is being lead by
UNEP.
Species Plantarum
100. Species Plantarum (or, Flora of the World) operates under the
auspices of the International Organisation for Plant Information (a Commission
of IUBS). Planning is well advanced, but implementation has been slowed
by a lack of resources.
101. The project aims at producing worldwide accounts of flowering plants,
including full synonymies, descriptions of taxa to species level or below,
and identification keys on a uniform worldwide basis, within a very short
time. Another goal is to stimulate job growth and taxonomic training and
experience on a worldwide basis. The first treatments, and some subsequent
ones, will almost certainly be donated. Funding will be required to commission
other treatments, or parts of treatments, in order to ensure timely progress.
Such funding would achieve two of the major objectives of the Global Taxonomy
Initiative outlined below: the provision of identification materials for
important groups on a uniform basis; and the direct generation of employment
and experience for taxonomists on a worldwide, distributed basis.
4. OPTIONS FOR ACTION
102. As recommended by Courrier (1992), "capacities for undertaking
[taxonomic] research and disseminating data should be developed close to
those who need the information -- at the national or sub-national level
-- though the support of international networks is vital". Furthermore,
actions should, to the extent possible, build on existing capacities. Thus,
the development of national biological collections should be based on existing
museums and herbaria, and within the framework of biological departments
in universities with significant collections. Likewise, the training of
professional and technical staff should take place in a formalised collaboration
between such collecting institutions, tertiary institutions, and other
agencies with the appropriate expertise.
103. Where no adequate collection facilities exist, the opportunity
should be taken to plan development in close proximity to an appropriate
tertiary institution.
104. National affiliation with regional or international networks with
relevant aims should be sought in order to facilitate the sharing of experiences,
establishing collaborative programs to avoid duplication of resources and
create consortium approaches to international funding sources in areas
of common interest. Where bilateral arrangements are in place between developing
and developed countries these should be further pursued within the framework
of national strategies for taxonomic capacity building.
105. With these points in mind, it is clear from the preceding sections,
however, that each country must develop its own programs and priorities
for developing taxonomic capacity to meet specific national needs and goals.
On this basis it would seem counter-productive to propose here prescriptive
actions and solutions.
106. It is possible, however, to outline a framework for a Global Taxonomy
Initiative within which developing countries can address taxonomic capacity-building
in partnership with neighbours and the international community, and bring
proposals forward to international funding bodies individually or in consortia
of countries with overlapping interests. This proposed framework is presented
diagrammatically in Annex 2, and is discussed below.
107. Centres of Excellence (CEs) as operational focal points are proposed,
not as mandatory components, but from the conceptual point of view that
such centres would serve partly to provide the necessary critical taxonomic
expert mass-effect for research planning, giving advice, and policy development,
and partly to raise the national profile of taxonomy and underscore its
fundamental role.
108. Provincial Centres (PCs), or equivalent, should preferably be administered
as distributed elements of central taxonomic institutions (CEs or otherwise)
with responsibilities attuned to national planning and priorities. Where
established within existing provincial research or educational institutions,
their relationship with the CE should be formalised. They would have a
pivotal role in developing and disseminating educational material about
biodiversity and the role of taxonomy in collaboration with local communities,
and in providing an invaluable training ground for future taxonomists through
participation in inventories, surveys and ecological studies. With minimum
expert taxonomic supervision, PCs could be operated by trained parataxonomists
and educators, with local assistance for field work.
109. Within a broad framework, as outlined in Annex 2, individual nations
would set in place their own administrative, planning and policy-development
structures based on specific national circumstances, priorities, existing
government mechanisms and local traditions. A high-level national advisory
or coordinating council charged with overseeing the implementation of taxonomic
capacity building and providing recommendations to government on priorities
and broad directions for the national taxonomic effort would ensure coherence
and focus. If established, such advisory bodies should preferably be chaired
by, or at least report directly to, the responsible government minister.
110. The framework provides numerous options for adaptation and scoping.
These range from an individual nation developing the desired capacity using
national resources with support from bilateral partners or regional fora,
to large-scale consortia requiring international funding support. Each
nation or consortium could, within the global, regional or national framework,
choose to adopt or adapt infrastructures and administrative and funding
arrangements tested in other countries with the added benefit of lessons
already learnt. The model allows all levels of national, regional and international
expertise and experience to become involved in various aspects of structured
capacity building, at various times and with varying contributions of resources.
5. THE ROLE OF THE CONVENTION IN DEVELOPING TAXONOMIC CAPACITY
111. Even though it is undeniable that at every level there is under-resourcing
of taxonomy, and although it can be taken as axiomatic that the discovery
and description of all the world's species is a sound and legitimate goal,
the crucial question within the context of the Convention is: to what extent
is the "taxonomic impediment" invariably a limiting step in fulfilling
the aims of the Convention? Indeed, it needs to be recognised that the
national taxonomic needs of the Parties do not necessarily coincide with
the taxonomic capacity needed to implement the Convention.
112. The Parties therefore need to be mindful of the basic requirements
of the Convention when considering what is the optimal level of taxonomic
capacity. Similarly, the COP and the SBSTTA will wish to be mindful of
these constraints and to focus their attention and support in the areas
where they can be most effective and are most critical in terms of meeting
the objectives of the Convention.
113. Taxonomic knowledge is required to address at least four basic
issues under the remit of the Convention, including: the identification
of areas of high diversity; of taxa under threat,;of taxa that are or may
be of value to humankind; and improving the understanding of ecosystem
functioning.
114. To be of value in fulfilling these functions, taxonomic information
needs to be supplemented with additional information, particularly concerning
the distribution of the species identified. It is important to consider
whether greater benefit at present would be gained from increasing the
information on already described taxa or from increasing the number of
described taxa. The two activities should not, of course, be regarded as
mutually exclusive, but their relative importance should be carefully weighed.
In this respect, the SBSTTA will no doubt wish to be mindful of its consideration
of items 3.1, 3.2 and 3.3 of the provisional agenda of this meeting of
the SBSTTA.
115. It is taken as given that financial resources are limited, therefore,
in the context of the Convention, attempts should be made to analyse the
cost-benefit ratios of different research strategies. With limited resources,
and with the urgency of action required to maintain the world's biodiversity,
it is recommended that the concept of "optimal ignorance" be
invoked, whereby ignorance is reduced to a level at which it ceases to
impede judgement on the best action (but not to zero). Such an approach
applied to critical areas within the Convention gives some idea of the
level of taxonomic capacity that is in fact needed, compared to what is
desirable from a taxonomist's perspective.
What proportion of existing species must be known and described?
116. Increasing the accuracy of estimates of global species richness
(and a linked parameter - the current rate of species extinction) is an
important scientific pursuit, but may not be a primary goal in the context
of the Convention. For example, it is questionable whether the immense
sampling and analytic effort required to collect and identify the possible
500,000 to 1,000,000 undescribed nematode species would be justified in
terms of the ability of the information generated to affect materially
the management and use of the world's biodiversity. This probably remains
true despite the fact that nematodes as a group are of great economic importance
(chiefly as parasites and pests of both plants and animals) and are extensively
used in scientific research. In most circumstances, it is likely that filling
gaps in knowledge of the geographic distribution or population condition
of described species, particularly in ecologically or economically important
groups, and in developing countries, will make a more immediate contribution
to achieving the aims of the Convention.
Identifying areas of high diversity
117. Similarly, in the question of identifying areas of high diversity,
it is not clear whether the very large effort required to inventory all
taxa in any given geographical area is warranted in terms of increased
accuracy. Sampling and inventorying invariably follows a pattern of diminishing
returns, so that fairly rapidly the increase in information gained per
unit effort becomes very small. Also, some forms of assessment in this
field do not necessarily require the naming and classification of all organisms
collected.
118. The emerging evidence that areas of high diversity for one taxonomic
group may be poorly correlated with those of other groups makes it difficult
to assess the significance of such areas. It also remains a moot point
whether the discovery that patterns of diversity in hitherto undescribed
taxa differed greatly from known patterns (largely of macrofauna and vascular
plants) would materially affect planning for biodiversity conservation
and, if so, in what way.
Understanding ecosystem functioning
119. The relationship between systematics and the study of ecosystem
functioning is not a straightforward one. Studies of ecosystem functioning
essentially concern attempts to discern patterns at various spatial and
temporal scales in the interactions between different organisms and between
organisms and their physical environment. There is obviously a need to
be able to identify and distinguish the elements of ecosystems under study
to do this, but it is not clear that a full understanding of systematic
relationships is necessary. Furthermore it will be impossible, particularly
in diverse ecosystems, ever to look at the relationships between more than
a fraction of the species present so that full taxonomic inventories are
likely to be redundant.
120. There is admittedly a danger in this approach in that crucial aspects
of ecosystem functioning may be overlooked because of inadequate taxonomic
knowledge. For example, the relationship between diversity and the maintenance
of ecological processes, particularly those involving decomposition processes
in highly diverse ecosystems such as tropical moist forests, is a crucial
area of study in ecology and one that requires a solid understanding of
taxonomic diversity.
Sustainable use of species
121. Assessing the sustainability of current use of wild species
demands that the population units in question can be identified, characterised,
and the demographic links between them determined. Establishing and maintaining
sound species-level taxonomy is clearly a prerequisite. On the other hand,
the initial investigation of potential benefits from wild species not in
use, e.g., prospecting for genetic resources of medicinal importance, demands
only that specimens can be at first identified to family or generic level.
If a species in some given genus or family already has an established use,
it can be predicted that another population not in use but falling within
that same genus or family (regardless of its precise taxonomic level) has
a significant probability of sharing genes that are the basis for desirable
biochemical or production characteristics.
Assessing threatened species
122. Determining whether a given taxon is under threat is a rigorous
undertaking requiring quite detailed information on the status and distribution
of that taxon. It is evident from the global assessments carried out to
compile the IUCN Red List and other national and international registers
of threatened species that there is inadequate information at present to
assess thoroughly more than a small proportion of currently known species.
Vastly increasing the number of species to be assessed will compound this
problem.
6. CONCLUSIONS
123. Solutions to the problem of inadequate taxonomic knowledge
and the shortage of systematists, particularly in many of the most species-rich
tropical countries, must be both strategic and pragmatic.
From the point of view of maintaining biodiversity there may be little
point in investing heavily in systematics unless there are programmes in
place that will make use of the information and of the human resources
generated by such an investment. Moreover, as elaborated above, it is evident
that the relationship between taxonomy and the assessment and management
of biodiversity is not a straightforward one. A greater understanding of
the crucial links between the two is necessary before detailed programmes
are developed.
124. Proposed solutions to the "taxonomic impediment" follow.
The foremost priority, however, is for each country to undertake a user-needs
analysis. This will allow a first approximation to the central question
of balance: what proportion of total resources available for biodiversity
conservation should be allocated to systematics as opposed to other areas?
125. For some countries, the level of taxonomic knowledge or expertise
may be sufficiently high that there is no fundamental taxonomic impediment
to that country's effective implementation of the Convention. For other
countries, probably most or all of those in the biodiversity-rich low latitudes,
there is likely to be a very significant taxonomic impediment. This will
variously lie in a lack of in-country taxonomic expertise, in a lack of
access to existing specimens or literature, or in other problems.
Make better use of existing resources
126. Regardless of the particular needs of a Party, the better use
of existing taxonomic information is a desirable policy and one that can
only be effectively addressed at the global rather than national level;
it would also relieve many of the taxonomic problems besetting developing
countries. A great deal of existing taxonomic information remains very
little used; many taxonomic collections are infrequently accessed. This
may be because there is no demand or because the information or the collections
are difficult to access. Lack of demand may reflect a lack of current use
for the information or may be because potential users are unaware of the
existence, or the value, of the information. The creation of use for the
information lies outside the realm of systematics, but an analysis of user
needs should be fundamental to any organised planning for development of
the discipline.
127. Improving awareness of and access to the resource are problems
to be tackled primarily by the systematic community and will entail a reappraisal
of current working practices. The Convention and its bodies are well placed
to make a significant contribution to improving access. Obviously, the
development of the clearing-house mechanism can help the dissemination
of existing information, especially from those institutions in the developed
world that are the repository of a large proportion of the world's taxonomic
information to developing countries where it is most needed (further details
about the state of the clearing-house mechanism are given in document UNEP/CBD/SBSTTA/2/9).
128. The Convention as a whole is also well placed to provide further
support for developing taxonomic capacity. What follows is a list of areas
that would facilitate the development of taxonomic capacity and that the
SBSTTA may wish to consider how the Convention can contribute to:
(a) Taxonomic standards A central justification
for the practice of taxonomy is to ensure that each species has a single,
universally recognised name (the Latin binomial) so that wherever this
is used there is no doubt about the identity of the species being referred
to. There is continual flux in species names but no centralised system
to record and make available information on appropriate scientific names
and authorities (and, incidentally, no means of counting accurately the
number of described species). The widespread adoption of standard taxonomic
systems, buffered from continual short-term change in nomenclature, should
be encouraged.
(b) Taxonomic rules Research into the validity
and taxonomic precedence of names is a fundamental part of the practice
of taxonomy, but it is also time-consuming and expensive to pursue. It
is desirable to streamline the decision-making process of those bodies
charged with ruling on the availability of disputed names.
(c) Electronic access Taxonomic lists, some
adopted as global standards, are increasingly maintained in electronic
format. Most of the world now has access to the Internet. There is a clear
need to develop a metadatabase of such lists that would facilitate electronic
access to them.
(d) Publication Standard taxonomic publications
are often several years in preparation, many months in the printing process
and, once published difficult to access in many parts of the world. Taxonomic
work is in itself time-consuming, but it is possible and desirable to make
the published work (perhaps in abstract form) readily available in every
country of the world.
e) Pragmatic approach Detailed research into
nomenclature and the morphology or other characters of specimens at hand
is traditionally the core work of taxonomists. In many, but not all, cases
the interest of biodiversity conservation could be best served by abbreviating
this process and making possible the rapid publication of key taxonomic
details rather than delaying the dissemination of results until a lengthy
monograph can be finalised.
Develop ways around the problem
129. Indicators A growing body of work is focused on using
information on some taxon (or other environmental feature) to indicate
some more generalised condition. The use of indicators is discussed in
more detail in the Note prepared by the Secretariat for the previous item
of the provisional agenda (document UNEP/CBD/SBSTTA/2/4). The SBSTTA may
wish to consider item 3.3 of the provisional agenda in light of the need
to support the development of taxonomic capacity in developing countries
as well as simply to review the effectiveness of measures taken in accordance
with the Convention.
130. Parataxonomists In many circumstances, persons with some
basic training in collection and/or in identification to some determined
taxonomic level, but without experience in the preparation of detailed
taxonomic monographs with all that this entails, can generate very useful
information on local diversity. This represents a sound compromise position
and one increasingly used in rapid survey techniques.
Investment and Support from the Developed Countries
131. The fundamental importance of continuity and of guaranteed,
long-term stability in funding for taxonomic institutions cannot be over-emphasised.
Declining levels of investment have been a major factor in the decreasing
levels of taxonomic capacity in the developed countries.
132. Support of some kind from the Convention will probably be critical
to initiating the necessary measures. One particularly successful programme
of support in this respects has been the UK's Darwin Initiative. Under
this Initiative the UK Government has provided a small fund to support
joint research initiatives to look into biodiversity issues, where one
party is a UK education or research institution and the other party is
an appropriate institution in a developing country. Such a scheme has
meant that the enormous wealth of the UK's taxonomic capacity has been
offered along with enough financial support to fund a medium-term research
programme. This is a particularly effective way of addressing the need
for more taxonomists because it not only provides financial support but
also encourages the transfer of technology, which, as noted before, is
so vital in this area. The SBSTTA may wish consider examining ways in
which this programme may be expanded so that other developed countries
rich in taxonomic resources and collections could contribute both financial
resources and technical support to developing taxonomic capacity building.
133. Core funding of a long-term nature is also crucial. As noted before,
support for this type of funding might be provided by the financial mechanism
of the Convention; the SBSTTA may wish to consider a recommendation to
the COP requesting the COP to amend the necessary guidelines to the GEF.
However, the SBSTTA may wish to consider less costly options and a more
organic or incremental approach to seeking financial support for the development
of taxonomic support. Many of the observations made above about facilitating
access to existing information would benefit from financial support from
the GEF. Indeed, there are a number of systematics proposals in the GEF
process already. The SBSTTA may wish to recommend to the COP specific
guidance about the type of systematics projects that would be most effective
in meeting the requirements of the Convention.
134. Centres of Excellence would no doubt benefit enormously if they
were given some award of excellence by the SBSTTA or the COP. It would
assist them in seeking funding from donors, private interests, and even
perhaps the GEF. It would also help them in seeking support in kind from
other institutions. For example, it might facilitate the exchange of personnel
from institutions in the developed countries to developing countries where
the institutional structure does not have an international reputation.
Such a scheme would have the attraction of requiring little financial
commitment. The SBSTTA may wish to consider developing a scheme under
which an award of excellence has some official seal of approval from the
Convention. The SBSTTA may, however, wish to consider supporting such
a scheme with the allocation of a limited number of scholarships in order
to provide a further catalyst to the exchange of personnel and technology.

ANNEX 1ANNEX 1
Examples of Significant Outcomes of Applied Taxonomy
1. Presented below are several brief case studies showing how
taxonomy has played a crucial role in providing solutions to, or cost saving
predictions on, otherwise intractable problems relating to sustainable
development, utilisation of genetic resources in primary industry, or environmentally
related human welfare issues generally in developing countries. The economic
and social gains are incalculable.
Genetic enhancement in primary industry
2. Tolerance in Cotton. Cultivated cotton has been developed
through the selection of desirable strains from a single species, Gossypium
hirsutum. This narrow genetic base (as well as broad-acre farming methods)
has resulted in cotton crops becoming increasingly susceptible to a wide
range of fungal and insect pests. Efforts to control these pests have led
to intensive spraying regimes, impacting heavily on the environment, including
the pollution of ground water and the decimation of non-target species.
Feeding cotton waste to cattle has, in the recent past, led to the contamination
of the human food chain with insecticide and fungicidal residues, leading
to large economic losses. Cultivated cotton also has a relatively narrow
water availability and temperature tolerance, limiting the areas in which
it can be grown.
3. Recent taxonomic work on Australian native Gossypium species has
identified taxa with several desirable characteristics, including cold
tolerance, lack of terpenoid aldehydes in seeds, and resistance to insects
and microbial pests. Hybridisation work is underway to introduce these
characteristics into cotton cultivars, to increase their disease resistance
and their climatic tolerance. Biological solutions to pest problems
offer longer term and safer alternatives to spraying regimes, while increased
climatic tolerance will allow cultivation in more marginal areas.
4. Tolerance in soybean. In recent years considerable work
has gone into better understanding the taxonomy of the genus Glycine. This
genus has two subgenera, subgenus Soja containing only the annual wild
species G. soja, and its cultivated descendant, G. max, and subgenus Glycine,
of 14 wild perennial species, all indigenous to Australia. Five of the
latter have only been discovered in the last 10 years, as part of the research
described below.
5. The perennial species range from the tropics to the arid zone and
the alpine areas of Australia, and have a wide range of characteristics
that could improve soybeans, including a perennial lifestyle, drought,
heat and cold tolerance, apparent insensitivity to daylength, and resistance
to fungal diseases such as that caused by Phakopsora pachyrhizi (soybean
leaf rust). Recent work by Australia has gone a long way towards transferring
these characteristics to the soybean, a staple food in many parts of the
world.
6. Spin-offs from this project have been the development of a cultivar
of Glycine tabacina as a ground cover in South Africa, and of a strain
of Glycine latifolia as a pasture plant in southern Queensland.
Environmental management
7. Control of introduced water fern. Water ferns of the
genus Salvinia live on the surface of ponds, lakes and waterways. In the
1950s and '60s an introduced species became an environmental pest with
serious economic and social implications in many parts of the tropics when
it spread out of control in all freshwater habitats, including rice paddies
and fish ponds, due to a lack of natural control agents. Nowhere was the
impact harsher in terms of affecting human society than in Papua New Guinea,
where waterways became completely blocked by metre-thick mats of the fern.
As local residents were deprived of the use of the resources of rivers
and their traditional means of inter-community communication, they were
forced to abandon their villages.
8. It became apparent that biological control would be the only effective
and environmentally acceptable means of averting a long-term disaster throughout
the tropics. The first step was to determine taxonomically the exact species
involved. It was found to be an undescribed species, now known as Salvinia
molesta. Its origin was traced to Brazil, where it was found to be controlled
by tiny weevils.
9. Further biocontrol experiments were largely unsuccessful until,
in the early 1980s, Australian entomologists undertook a detailed taxonomic
study of the weevils. They discovered that what was thought to be one species,
in fact comprised a species complex of which only one -- a previously undescribed
species now known as Cyrtobagous salviniae -- was the only effective control
agent for Salvinia. Within a year of applying this taxonomic breakthrough,
waterways in Papua New Guinea were cleared of the pest, and abandoned villages
were re-occupied. The environmental success and socio-economic benefits
of this control program were readily available to affected countries in
tropical Indo-Pacific and Africa.
10. Lichens as cheap and sensitive air pollution monitors.
In the last 30 years, evidence of the variable sensitivity of lichen species
to changes in air quality has led to their increasing use as cheap but
accurate biological monitors. Throughout western Europe and, more recently,
North America, the lichen floras in and around urban and industrial areas
have been mapped, and the environmental implications of depauperate vegetation
have had a considerable influence on planning and regulatory agencies.
This enhanced profile for what had been a neglected group of organisms
has had as its basis an increasing understanding of lichen taxonomy and,
concomitantly, more reliable lichen-mapping studies.
11. The ability to distinguish between apparently similar species of
lichen has led to the development of air quality monitoring kits. These
have enabled high-school children throughout Europe and North America to
undertake local surveys and provide reliable indications of air quality.
12. That solid and reliable taxonomy continues to underpin such studies
can be seen in the flurry of interest that recently accompanied the apparent
discovery of the lichen Lecanora conizaeoides in North America. This pollution-sensitive
species is the dominant lichen in urban and industrialised areas of western
Europe. However, a recent taxonomic monograph of the genus Lecanora was
able to confirm that this lichen had not in fact migrated across the Atlantic.
The American plant was shown to be a related species of minimal value as
a biological monitor.
Pest control in Agriculture
13. Taxonomy as a predictive tool. The Chinese wax-scale
insect, Ceroplastes siniensis, is a serious introduced pest in the citrus-growing
industry around the world. Early attempts to find natural enemies for biological
control failed largely because researchers assumed, on account of the bug's
scientific and common name, that its native habitat was to be found in
China. As it turned out, Ceroplastes siniensis does not occur in China
(its scientific name has a different origin), and its native habitat could
not be predicted from its choice of plants, because it attacks more than
200 plant species.
14. To narrow down the possibilities, an Australian entomologist embarked
upon a detailed taxonomic study and analysis of the evolutionary relationships
(phylogeny) among the more than 100 species known in the genus. The resulting
hypothesis suggested that Ceroplastes siniensis is closely related to a
small group of species native to south and central America. Consequently,
a search for the species in South America was undertaken, and in 1993 it
was discovered at La Plata in Argentina. It was also found that the native
populations were heavily parasitised by a local species of wasp, which
appeared to exert natural control over the wax-scale. The potential for
using the wasp as a biological control agent of introduced populations
of Ceroplastes siniensis without unintended effects is being investigated,
but predictions from a taxonomy-based hypothesis of evolution and origin
changed the hunt from a large-scale search on several continents to a well-focused
exercise.
15. Pest mites in horticulture and agriculture. In about 1950,
fewer than 20 species of the mite family Phytoseiidae were known. About
that time it was realised that this group of mites preys on and controls
another mite group, spider mites, which cause enormous damage to crop plants
all over the world. This discovery led to intensive taxonomic research,
with the result that more that 1000 phytoseiid mites have been described.
This biological diversity is now being exploited by the use of many species
in the control of spider mites and other plant pests in orchards and other
horticultural situations around the world. One of the most important phytoseiid
mites, only recently recognised scientifically, can provide complete protection
against spider mites in glasshouses. The genetic diversity in phytoseiid
mites is also being exploited to develop pesticide-resistant strains that
can be used in biological control in integrated pest-management programs.
16. Potato and beet pests. Many species of roundworms (nematodes)
attack crop plants, and are almost certainly responsible for the crop failures
in central Europe and Russia last century and early this century. At first,
the causal organism was unknown, but detailed research initially revealed
that the organisms were nematodes, and subsequently that different nematode
species and genera were involved. The recognition that different genera
were involved was, and continues to be, very important in devising control
strategies. Some whole genera are readily controlled by crop rotation.
In other genera, the exact species needs to be known to determine the correct
control approach. In both cases, taxonomy has had a major impact on the
development of crop rotation. Other nematode species have very wide host
ranges, so different methods must be used; but the identification of the
nematode involved is the crucial first step for determining occurrence
and control strategies, and for providing identification tools to ensure
that the correct strategy is adopted.
Soils
17. Conservation of arid zone soil crusts. It has been
recognised for many years that various cryptogram groups, particularly
bryophytes and lichens, were crucial in arid-zone soil crusts. In dry periods
these organisms bind the surface layers of the soil, greatly reducing wind
erosion of these thin soils and their scarce nutrients. Until recently,
however, the application of this knowledge to soil conservation had been
hampered by a lack of knowledge about the numbers and identities of the
organisms involved.
18. Recent investigations of the taxonomy of groups of Australian lichens,
and the production of monographs and floras dealing with lichens has provided
a new impetus for a greater understanding of the importance of lichens
and other non-vascular plants in the conservation of soil in arid and semi-arid
regions. In the last 5 years, taxonomic advances have enabled rangeland
scientists to identify lichen species and to produce illustrated guides
for agricultural advisers who will inform pastoralists of the value of
these organisms as indicators of soil quality.
19. The taxonomic knowledge in this case spurred the development of
management tools, which will have incalculable economic benefits in soil
conservation.
The importance of symbiosis
20. Orchids and Fungi. All orchids, both terrestrial and
epiphytic, are associated with and dependent upon certain types of fungi.
These fungi form an intimate (mycorrhizal) association with the roots of
the orchid. This symbiotic association is essential during the germination
phase of the orchid life cycle, and often during the remainder of the life
cycle as well. Research on the symbiotic germination of the orchid in the
presence of fungi showed that for each group or species of orchid there
is a preferred fungal partner. Without the appropriate fungus present,
the likelihood of a particular orchid seed germinating and/or a plant becoming
established and reaching maturity is extremely low. Knowledge of this relationship,
and the specific type of fungus needed for each orchid, has proved essential
in the germination and re-establishment of certain orchids into the wild.
A program involving the conservation and protection of rare and endangered
orchids in England has been running for 12 years, based on the knowledge
of the orchid/fungus relationship and their taxonomies.
21. Similar strategies are also of relevance to the cultivation of
orchids for horticulture and the cut flower trade. Plant breeders need
to understand the taxonomy of the groups that they are working with, as
well as the taxonomy of the fungus symbionts, to establish new seedlings
in cultivation. The other side of the coin is that the knowledge of which
groups of fungi are compatible with particular orchids provides additional
insights into the underlying relations of the orchids themselves.
