What leads farmers in climate-vulnerable countries to adopt climate-resilient crops?

Climate change exposes our food systems to increasing and potentially devastating risk. Less predictable and more extreme weather—from droughts to floods—increases farmers’ costs. Exposure to loss threatens domestic production in many developing countries to the point of imperiling their food security, and increasing the risk of disruption to international markets.
As the unpredictability and extremity of damaging weather increases through climate change, there is an urgent need to find climate resilient crops and crop varieties, and for decision-makers to promote them.
Biological diversity is a critical line of defense in the midst of this uncertainty. But which crops and which traits are best adapted to changing conditions? What are the characteristics that define a “climate-resilient” crop, how widely have they been adopted, and how successful have new varieties been in the face of extreme weather events? This evidence synthesis will look at 30 years of research to answer these questions.
