Scientists Behind 'Doomsday Seed Vault' Ready World's Crops For Climate Change

ScienceDaily (Sep. 18, 2008) — As climate change is credited as one of the main drivers behind soaring food prices, the Global Crop Diversity Trust is undertaking a major effort to search crop collections—from Azerbaijan to Nigeria—for the traits that could arm agriculture against the impact of future changes. Traits, such as drought resistance in wheat, or salinity tolerance in potato, will become essential as crops around the world have to adapt to new climate conditions.
Climate change is having the most negative impact in the poorest regions of the world, already causing a decrease in yields of most major food crops due to droughts, floods, increasingly salty soils and higher temperatures.
Crop diversity is the raw material needed for improving and adapting food crops to harsher climate conditions and constantly evolving pests and diseases. However, it is disappearing from many of the places where it has been placed for safekeeping—the world's genebanks. Compounding the fact that it is not well conserved is the fact that it is not well understood. A lack of readily available and accurate data on key traits can severely hinder plant breeders' efforts to identify material they can use to breed new varieties best suited for the climates most countries will experience in the coming decades. The support provided by the Global Crop Diversity Trust will not only rescue collections which are at risk, but enable breeders and others to screen collections for important characteristics.
"Our crops must produce more food, on the same amount of land, with less water, and more expensive energy," said Cary Fowler, Executive Director of the Global Crop Diversity Trust. "This, on top of climate change, poses an unprecedented challenge to farming. There is no possible scenario in which we can continue to grow the food we require without crop diversity. Through our grants we seek, as a matter of urgency, to rescue threatened crop collections and better understand and conserve crop diversity."
