Scientists have hailed the emergence of heat-tolerant beans, but there are fears corporate interests in Africa’s seed sector will wrest control from local farmers

CGIAR Climate's insight:

In 2012, CGIAR researchers began to test more than 1,000 types of beans in a bid to find “heat beater” beans able to grow amid high temperatures and drought. Scientists cultivated test plots on Colombia’s Caribbean coast and in greenhouses, before eventually discovering 30 heat-tolerant bean types that can withstand a 4C increase in temperature. CGIAR said it used natural breeding to discover the seed.
