Adaptation is climate-change jargon for everything that people can do to avoid the effects of rising temperatures, from building higher seawalls to installing air conditioning.
Even if you're just talking about farming, the list of possible adaptations is long. It includes irrigation, switching to crop varieties that can better withstand high temperatures, planting earlier to take advantage of longer growing seasons, fighting new insect pests, and building new transportation infrastructure that will allow countries to move food to where it is needed most.
International donors, including the World Bank, are now pouring money into research on "climate smart agriculture." They're trying out specific innovations among farmers in 15 "climate smart villages" that have been identified in sub-Saharan Africa and South Asia.
In one area of Senegal, for instance, farmers are now getting more accurate weather forecasts, delivered via cell phones. Andy Jarvis, of the International Center for Tropical Agriculture, says these forecasts are vitally important, because farmers want to plant their crops just as the rains start, and the true start of the rainy season can't be easily predicted.
It may vary, from one year to the next, by a month or more, and farmers can easily be fooled into planting too early by a small rain that's not sustained. Jarvis says this program is now expanding to reach more farmers.

According to this week's report from the IPCC, adaptive measures like these offer significant benefits — like boosting the yields of major grain crops by an estimated 15 to 18 percent — compared to current yields.
At the same time, the report warned that if average temperatures keep increasing, farmers and consumers would have to adapt in more fundamental ways. Farmers would be forced to grow different crops entirely, or leave their traditional farming areas, and consume would have to get used to entirely new mix of foods.
Come 2030, we might just have to develop a taste for sorghum biscuits.
