An online tool shows which technologies will do the most to help farmers improve yields, says Gordon Conway.

CGIAR Climate's insight:

An online tool developed by the International Food Policy Research Institute (IFPRI), and launched earlier this year, allows policymakers to identify which technologies or practices (out of 10 that were modelled) will do most to improve yields in their region, taking predicted climate change conditions into account.  The results for sub-Saharan Africa were striking. For instance, the joint adoption of no-till agriculture and drought-tolerant crops could as much as triple yields by 2050.
