The CGIAR Genebanks - Seeds
for Life
The July 2006 Story of the Month will run
for both July and August . We wish all our readers a peaceful and
restful summer.
Among the many valuable public goods of the CGIAR
that are put to work for the benefit of the world's poor are
the 600,000 plus accessions of crop, forage and agroforestry
species held in the genebanks of 11 of the CGIAR Centres (see Box).
These collections represent the largest international effort on
long-term conservation. Their huge reserves of diversity are rich
in traditional varieties and landraces, non-domesticated species,
obsolete cultivars, breeding lines and genetic stocks. Many of the
accessions no longer exist elsewhere, having fallen out of use by
farmers and/or become extinct.
The collections provide insurance to underwrite food security
and human well-being in the future. Examples abound of leaps
forward in crop productivity and quality, and in food security and
human health, that have resulted from drawing on the CGIAR genebank
riches. In the case of cereals alone, the Centres have used wild
relatives to transfer desirable traits to a variety of crops such
as the successful use by CIMMYT of Triticum polonicum to
increase wheat spike size by 30-50%. ICARDA has transferred stripe
and leaf rust resistance from wild Triticum species and
from Aegilops speltoides into durum wheat. IRRI has
incorporated disease and pest resistance traits, acid sulphate
tolerance and male sterility from five wild rice species into
commercial rice varieties.
The CGIAR genebanks have also come to the aid of war-ravaged
countries including Angola, Cambodia, East Timor, Rwanda, Somalia
and Sudan. Timely action by the Centres has helped restore
agricultural production in these countries, just as it has in other
locations in the aftermath of natural disasters such as Hurricane
Mitch impacting on Central America, and the many countries affected
by the Asian tsunami.
The CGIAR genebanks hold a total of 629,022
accessions of crops and their wild relatives of which 594,686 are
designated as in-trust, as shown below.

Collections in trust
The CGIAR collections originated as genetic resources to service
the plant breeding programmes of the Centres; yet over time they
have become of much wider significance due to their unique content,
the extent to which they are characterised and documented, and
their ease of availability. The CGIAR genebanks currently
distribute up to 50,000 samples per year to researchers and plant
breeders in national agricultural and research institutes north and
south. Moreover, the genebanks are a focus for the gathering,
refinement and sharing of knowledge and technologies, for capacity
building, and for advanced research applying cutting-edge
science.
The public goods status of the collections was affirmed in 1994
when they were placed in trust for the world community under
interim agreements with the Food and Agriculture Organization of
the United Nations (FAO). This status will be formalised on the
occasion of the World Food Day celebrations in October 2006, when
each Centre will sign a definitive in-trust agreement with the
Governing Body of the International Treaty on Plant Genetic
Resources for Food and Agriculture. Another important step
enhancing the status of the collections was taken in June 2006,
when the Governing Body adopted a simple, uniform contract - the
Standard Material Transfer Agreement - that will facilitate access
to the collections and trigger benefit-sharing payment of royalties
within the multilateral System created by the Treaty. This opens up
a new era of grater global collaboration based on transparency,
good-will and trust.
Securing the resources
In becoming a partner in the in-trust agreements,
the CGIAR made a weighty commitment, pledging to the world to
secure the safety of the collections and make them accessible. The
dynamic, vital nature of genetic resources is both their strength -
they can be used without being used up - and their Achilles heel.
Thus, they are not riches that can simply be placed under lock and
key and withdrawn when needed; rather they need to be maintained
under carefully controlled conditions to maintain their health and
viability. Moreover, their full value can only be realised if their
qualities be known and documented.
Most of the accessions in the collections can be stored as seed
and require controlled conditions of temperature and humidity to
maintain viability. However, a small but significant number of
accessions, particularly of root and tuber crops, can only be
stored as living plants or in vitro plantlets. These
present particular challenges to maintain their viability and
stability. Across the range of accessions, demanding maintenance
routines are applied to check viability over time and to regenerate
for conservation over extended periods and to generate material for
use, with safety duplication of accessions at a second site to
underwrite security. Thus, genebanking in the CGIAR is a complex
undertaking both practically and conceptually with a significant
cost, infrastructural demands and expertise requirements.
Strength through collective action
The CGIAR's comparative advantage in the genetic resources
arena relates to both its unique genebank holdings and the capacity
that the Centres have for concerted and timely action as in the
case of the disasters cited above. The latter quality has also come
to the fore in the context of meeting the in-trust commitments. For
over a decade, this has been a central concern for the CGIAR
genebanks and their convening mechanism the System-wide Genetic
Resources Programme. From the time of its creation in 1994, the
SGRP has addressed three critical issues regarding the collections:
(i) transparent and ready availability to users, (ii) the
achievement of high standards of conservation, and (iii)
sustainability of funding in the long term.
The first of these issues led to the creation of SINGER, the System-wide Information
Network for Genetic Resources. SINGER has assisted the Centres
to standardize and document information on their collections, and
apply web technologies to network their genebank data. Through
SINGER, users have a single entry point for interrogating
information on the collections and finding the diversity that they
need to meet their breeding and other objectives.
As well as serving a key role in transparently meeting the
in-trust commitments, SINGER is also emerging a powerful research
tool and mechanism for monitoring dynamic process over time such as
tracking the flow of material distributed from the collections. One
recent study has, for example, shown that the principal
beneficiaries of the CGIAR collections have been developing
countries, representing more than 80% of all recipients. In
addition, the flow of material from developed to developing
countries is twice the rate of that in the opposite direction, and
developing countries have requested the same material twice as
frequently as developed countries, reflecting the important service
of the CGIAR genebanks to national agricultural research needs in
the developing world.
Investing in the future
In addressing the second issue on genebank
standards, SGRP conducted a detailed review which revealed that,
while the CGIAR collections were generally being maintained to high
standards, there were concerns in terms of the quality of some
genebank facilities, and there were backlogs in processing material
into storage or through routine maintenance procedures and into
safety duplication. This meant that the CGIAR genebanks'
aspirations to set and adhere to best practices and to minimise
risk to the collections were compromised. This problem was
intimately linked to the third issue of security of long-term
funding in a financial climate dependent on annual budgeting
decisions. Accordingly, a strategic approach was urgently needed to
upgrade the genebanks and relieve funding concerns.
To provide a rational foundation for developing a funding
strategy, SGRP commissioned a costing study carried out by IFPRI
and completed in 2001. This study has enabled the Centres to
calculate their ongoing costs, and has also provided a much needed
input into the arithmetic of conservation that is central to the
efforts of the Global Crop
Diversity Trust. Founded by FAO and by IPGRI acting on behalf
of the CGIAR, and emerging from an SGRP initiative, the Trust is
mobilizing an endowment fund that will support important
international collections in the CGIAR and elsewhere in perpetuity.
But let us turn back to more immediate concerns: bringing the CGIAR
genebanks up to standard.
Support from the World Bank
The SGRP review provided the genebanks with the information to
set priorities and negotiate Centre support but the scale of the
problem required a significant injection of additional funding.
Fortunately this was forthcoming from the World Bank in the form of
a grant of US$ 13.6 million to fund the "Global Public Goods
Rehabilitation Project" (GPG I) . Running from mid-2003 and
currently drawing to conclusion, the project has supported
upgrading of critical genebank infrastructure and functions in the
11 Centres holding plant collections. These functions relate to
conservation per se as well as health, characterization,
information management and supply to users. An external review of
the project in 2005 revealed substantial progress in meeting the
project's goals. In a massive effort giving attention to nearly
50% of all in-trust accessions to improve the quality of their
management, a total of 275,265 had been processed, of which 118,908
had been transferred to storage, 190,112 regenerated, 152,468
placed in safety back-up, 84,223 characterized, and 128,145 health
tested. In parallel, several Centres have new and improved storage
facilities, and the quality and quantity of information available
on the collections have been improved. The 2006 report will be
completed in 2007.
Down the road
A second phase project is in the works (GPG II) , and is
proposed to run from 2007 to 2009, focusing on completing tasks
relating to the security, management and accessibility of the
collections, with attention to the assessment and management of
risks. A platform for collaborative efforts will include a
SINGER-based one-stop entry point for ordering from the
collections. The project is foreseen as the final step in readying
the collections for a sustainable future and as such is giving due
attention to cost-effective management, especially regarding the
collections held in common across the Centres.
The project targets its actions beyond the CGIAR through, for
example, the development of guidelines on best practices with wide
applicability in other collections. And a critical role is foreseen
for the CGIAR Centres in the development of a global system for
conservation and use of crop diversity as an instrument for
development. FAO will be a key partner in this endeavour, which
addresses specific goals of the International Treaty, the Global
Plan of Action, and the Global Crop Diversity Trust, that all
represent landmarks along the long road of collaboration between
the CGIAR and FAO on plant genetic resources for food and
agriculture.
The CGIAR wishes to thank the System-wide Genetic
Resources Programme for contributing this story.
