Mexico City, Mexico
January 23, 2008
At the end of January, more than
200,000 crop varieties from Asia, Africa, Latin America and the
Middle East—drawn from vast seed collections maintained by the
Consultative Group on
International Agricultural Research (CGIAR)—will be shipped
to a remote island near the Arctic Circle, where they will be
stored in the Svalbard Global Seed Vault (SGSV), a facility
capable of preserving their vitality for thousands of years.
The cornucopia of rice, wheat, beans, sorghum, sweet potatoes,
lentils, chick peas and a host of other food, forage and
agroforestry plants is to be safeguarded in the facility, which
was created as a repository of last resort for humanity’s
agricultural heritage. The seeds will be shipped to the village
of Longyearbyen on Norway’s Svalbard archipelago, where the
vault has been constructed on a mountain deep inside the Arctic
permafrost.
The vault was built by the
Norwegian government as a service to the global community, and a
Rome-based international NGO,
The Global Crop Diversity Trust,
will fund its operation. The vault will open on February 26,
2008.
This first installment from the CGIAR collections will contain
duplicates from international agricultural research centers
based in Benin, Colombia, Ethiopia, India, Kenya, Mexico,
Nigeria, Peru, the Philippines and Syria. Collectively, the
CGIAR centers maintain 600,000 plant varieties in crop
genebanks, which are widely viewed as the foundation of global
efforts to conserve agricultural biodiversity.
“Our ability to endow this facility with such an impressive
array of diversity is a powerful testament to the incredible
work of scientists at our centers, who have been so dedicated to
ensuring the survival of the world’s most important crop
species,” said Emile Frison, Director General of Rome-based
Bioversity International, which coordinates CGIAR crop diversity
initiatives.
“The CGIAR collections are the ‘crown jewels’ of international
agriculture,” said Cary Fowler, Executive Director of the Global
Crop Diversity Trust, which will cover the costs of preparing,
packaging and transporting CGIAR seeds to the Arctic. “They
include the world’s largest and most diverse collections of
rice, wheat, maize and beans. Many traditional landraces of
these crops would have been lost had they not been collected and
stored in the genebanks.”
For example, the wheat collection held just outside Mexico City
by the CGIAR-supported International Maize and Wheat Improvement
Center (CIMMYT) contains 150,000 unique samples of wheat and its
relatives from more than 100 countries. It is the largest
unified collection in the world for a single crop. Overall, the
maize collection represents nearly 90 percent of maize diversity
in the Americas, where the crop originated. CIMMYT will continue
to send yearly shipments of regenerated seed until the entire
collection of maize and wheat has been backed up at Svalbard.
Storage of these and all the other seeds at Svalbard is intended
to ensure that they will be available for bolstering food
security should a manmade or natural disaster threaten
agricultural systems, or even the genebanks themselves, at any
point in the future.
“We need to understand that genebanks are not seed museums but
the repositories of vital, living resources that are used almost
every day in the never-ending battle against major threats to
food production,” Bioversity International’s Frison said. “We’re
going to need this diversity to breed new varieties that can
adapt to climate change, new diseases and other rapidly emerging
threats.”
Why are genebanks important?
The CGIAR collections are famous in plant breeding circles as a
treasure trove for plant breeders searching for traits to help
them combat destructive crop diseases and pests, such as the
black sigatoka fungus, which is devastating banana production in
East Africa, and grain borer beetle, which is destroying maize
in Kenya.
Just from January to August of 2007, CGIAR centers distributed
almost 100,000 samples. The materials mainly go to researchers
and plant breeders seeking genetic traits to create new crop
varieties that offer such benefits as higher yields, improved
nutritional value, resistance to pests and diseases, and the
ability to survive changing climatic conditions, which are
expected to make floods and drought more frequent.
In addition, these collections have often been used to help
restore agricultural systems after conflicts and natural
disasters.
For example, among the 135,000 food and forage seeds maintained
at the CGIAR-supported International Center for Agricultural
Research in the Dry Areas (ICARDA) in Aleppo, Syria, 3,000
varieties are native to Afghanistan, and 1,000 are from Iraq.
The seeds preserved have been used to help revitalize crop
diversity in these war-torn regions.
“Svalbard will be able to help replenish genebanks if they’re
hit,” said Cary Fowler. Iraq’s genebank in the town of Abu
Ghraib was ransacked by looters in 2003. Fortunately there was a
safety duplicate at the CGIAR center in Syria. Typhoon Xangsane
seriously damaged the genebank of the Philippines national rice
genebank in 2006. “Unfortunately, these kinds of national
genebank horror stories are fairly common place,” said Fowler.
“The Svalbard Global Seed Vault makes the CGIAR’s genebank
collections safer than ever.”
After the Asian tsunami disaster of 2004, the CGIAR-supported
International Rice Research Institute (IRRI) used its
collections to provide farmers with rice varieties suitable for
growing in fields that had been inundated with salt water. The
genebank at the CGIAR-supported International Center for
Tropical Agriculture (CIAT) in Palmira, Colombia was
instrumental in providing bean varieties to farmers in Honduras
and Nicaragua in the aftermath of Hurricane Mitch in 1998.
According to Geoff Hawtin, Acting Director General of CIAT and
former executive director of the Rome-based Global Crop
Diversity Trust, “The shipments going to Svalbard from the CGIAR
genebanks are a vital measure for further safeguarding the
world’s crop collections. With coming climatic changes, higher
food prices, and expanding markets for biofuels, our best
available options for progress, if not survival, will be in what
we have conserved and studied against all thinkable
predictions.”
The Consultative Group on International Agricultural Research
(CGIAR), established in 1971, is a strategic partnership of
countries, international and regional organizations and private
foundations supporting the work of 15 international agricultural
research Centers. In collaboration with national agricultural
research systems, civil society and the private sector, the
CGIAR fosters sustainable agricultural growth through
high-quality science aimed at benefiting the poor through
stronger food security, better human nutrition and health ,
higher incomes and improved management of natural resources.
The mission of The Global
Crop Diversity Trust is to ensure the conservation and
availability of crop diversity for food security worldwide.
Although crop diversity is fundamental to fighting hunger and to
the very future of agriculture, funding is unreliable and
diversity is being lost. The Trust is the only organization
working worldwide to solve this problem.

[Pathogens are changing and adapting constantly. New
mutant strains with increased virulence emerge
resulting in breakdown of genetic resistance in crop
hosts. Recent examples are the fungal pathogens of
wheat stem rust (_Puccinia graminis_ f. sp.
_tritici_, strain Ug99) and potato late blight
(_Phytophthora infestans_, multiple new strains),
which are causing worldwide concern, as well as the
virulent strain of _Cassava brown streak virus_
threatening food security in Africa (for further
information please see previous ProMED-mail reports
listed below).
While fungal or bacterial plant diseases may be
susceptible to chemical control in the short term,
sustainable control of these, as well as control of
virus diseases in general, rely largely on the use
of resistant crop varieties. When genetic resistance
of a crop is broken down by a new pathogen strain,
breeding of new crop varieties resistant to the new
strains depends on the availability of alternative
resistance genes. In many cases, modern crop
cultivars have been bred to the immediate
requirements of today's agriculture, resulting in
the large scale loss of such alternative resistance
mechanisms. However, a range of resistance germplasm
is often found in less specialised "old" cultivars
or wild relatives of the crop. Therefore, the
preservation of these genetic
resources is absolutely vital for global agriculture
being able to counteract the constant evolution of
plant pathogens.
The establishment of this long term seed depository
serving as a back-up of germplasm collections for
both crop cultivars and wild crop relatives
contributes significantly to food security worldwide
and is a credit to the international community.
