填空题 The shorter growing seasons expected with climate change over the next 40 years will endanger hundreds of millions of already poor people in the global tropics, say researchers 1 the world’s leading agricultural organizations.
The effects of climate change are likely to be seen across the entire tropical zone but many areas previously considered to be relatively food secure are likely to become highly 2 droughts, extreme weather and higher temperatures, say the researchers with the Consultative Group on International Agricultural Research.

More than 300 million people in south Asia are likely to be affected even with a 5% decrease in the length of the growing season. Higher peak temperatures are also expected to take a heavy 4 on food producers. Today there are 56 million crop-dependent people in parts of west Africa and India who live in areas where, in 40 years, maximum daily temperatures could be higher than 30℃. This is close to the maximum temperature that beans can tolerate, while corn and rice yields suffer when temperatures exceed this level.
“We are starting to see much more clearly where the effects of climate change on agriculture could 5 hunger and poverty,” said research leader Patti Kristjanson. Farmers already adapt to variable weather by changing their planting schedules. What this study suggests is that the speed of climate shifts and the magnitude of the changes required to adapt could be much greater.
