Genomic gymnastics help sorghum plant survive drought

Scorching temperatures and parched earth are no match for the sorghum plant—this cereal crop, native to Africa and Australia, will remain green and productive, even under conditions that would render other plants brown, ...

Raising plants to withstand climate change

Success with improving a model plant's response to harsh conditions is leading plant molecular researchers to move to food crops including wheat, barley, rice and chickpeas.

Drought

A drought is an extended period of months or years when a region notes a deficiency in its water supply. Generally, this occurs when a region receives consistently below average precipitation. It can have a substantial impact on the ecosystem and agriculture of the affected region. Although droughts can persist for several years, even a short, intense drought can cause significant damage and harm the local economy. This global phenomenon has a widespread impact on agriculture. The United Nations estimates that an area of fertile soil the size of Ukraine is lost every year because of drought, deforestation, and climate instability. Lengthy periods of drought have long been a key trigger for mass migration and played a key role in a number of ongoing migrations and other humanitarian crises in the Horn of Africa and the Sahel.
