Climate-Ready Crops Needed to Prepare Australian and Pacific Rim Agriculture
for Climate Change, Says Global Seed Expert
Scientist Behind Doomsday Vault Calls for New Global System to Safeguard
Agriculture from Changing Climate at Crawford Fund Conference in Canberra
Nations will soon face an even greater food crisis unless the world puts a
premium on breeding new varieties of crops resistant to climate change,
warns Dr Cary Fowler, a leading expert on agriculture and Executive Director
of the Global Crop Diversity Trust, a Rome-based organization leading the
worldwide effort to conserve farm diversity.
Speaking at The Crawford Fund Annual Conference in Canberra, Fowler said,
"Adapting agriculture to climate change will require the development of a
new global system that will focus on conserving unique crop diversity and
making certain that diversity is legally and practically available to all,"
says Fowler, "If we don't, we will experience food shortages far worse than
the current crisis."
Fowler warned that food security in the Asia-Pacific region is threatened by
increased risk of drought, higher salinity in coastal areas, energy and
water constraints, low stockpiles, population growth, and new threats to
crops from pests and diseases. Extremes in temperature and rainfall have
already created serious problems for farmers -- in Australia as much as in
other parts of the world. Alarmingly, the 12 hottest years on record have
all occurred since 1990. A "perfect storm" is brewing, and new-and often
radically different-climate-ready varieties will be required for the
Confronted by this critical situation, hundreds of scientists, plant
breeders, farmers -- supported by the Global Crop Diversity Trust -- are
undertaking a rescue mission to identify and save as many distinct crop
varieties as possible. Globally, the poor depend inordinately on a group of
neglected crops, including roots and tubers, which are critical to
nutrition, food security, and livelihoods in many developing countries. In
Asia and the Pacific, for example, these crops serve as major sources of
Vitamin A and from 15-43% of the dietary energy needs in the Pacific,
depending on the island. Unless diversity is conserved, documented, and made
available to plant breeders, these crops will no longer be able to support
the communities that rely on them.
According to strategies whose development was supported by the Trust,
priority crops for the Asia-Pacific region include the sweet potato, one of
the world's top ten crops in terms of energy but whose various collections,
including one of global significance in Papua New Guinea (PNG), are in need
of proper management and sustainable financing. Other important crops
include various types of taro, especially the Giant Swamp Taro, which is
found exclusively in the Pacific, and while it is a classic "survival food"
it is neglected in terms of research and development; and fe'ii banana, a
uniquely Pacific type that has great potential in alleviating Vitamin A
deficiency. Fe'ii bananas are extremely poorly represented in global
collections, and material established in PNG and French Polynesia have
already been lost.
"We don't have the option of failing to get our agriculture ready for
climate change and ready to feed a growing world population, and that means
safeguarding collections" says Fowler. "There is no country in the world,
rich or poor, large or small, which is self-sufficient in the genetic
diversity of the crops which feed its people - no country can make it on its
own." Even large genebank collections typically contain only a small portion
of the number of samples held globally.
Australia is a good example. Its collections hold 3% of the wheat samples
found in genebanks globally. Ask anyone here whether they are confident that
Australian wheat production could continue to be on a sound footing were it
to be based solely on this 3%, and the response would certainly be "No,"
says Fowler. Moreover, a strain of wheat stem rust disease emerging from
East Africa is gravely threatening world wheat production, as scientists
believe it will move to India within the next couple of years, posing a high
risk of eventually reaching Australia via high altitude movements.
In his speech, Fowler focused on several priorities for the way forward.
Step one involves making an initial assessment of where the largest, most
important, but most vulnerable crop collections are, regenerating them
(because seed dies), and securing duplicates in another genebank. The Trust
has provided support to develop global strategies for more than 20 crops,
including identifying such collections. In parallel, endangered diversity
found in smaller collections needs to be identified. Crop and regional
networks are well placed to do that, and the Trust is providing financial
and technical support to regenerate samples held in the smaller collections
identified through networks.
Step two involves developing appropriate information and information
systems. This means learning more about the genebank's unique seed samples
themselves - an exercise that should, where feasible, be focused on traits
of high priority (e.g., screening collections for heat and drought
resistance). It also means developing the software tools - for genebank
management, and for globally searching multiple genebank holdings - that
will facilitate good management and effective use. Again, the Trust is
providing support for this.
Step three involves guaranteeing the long-term conservation and availability
of these collections - because this biological foundation of agriculture
will be as important far into the future as it is now. To provide permanent
financial security to the world's most important collections, the Trust is
raising an endowment fund, to which Australia is one of the earliest and
most generous contributors.
"With focus, pragmatism and determination, we will succeed," Fowler said.
"We will help ensure that agriculture is ready to promote development,
provide food security, and help humanity adapt to climate change and a new
age of resource constraints."
The Global Crop Diversity Trust (www.croptrust.org): The mission of the
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.
