In developing countries , ifpri found , irrigated wheat in 2050 would yield 34 % less than in 2000 , using ncar data ; and 28 % less going by csiro figures .

在发展中国家，ifpri发现，用ncar数据分析，灌溉小麦2050年比2000年减产34%，而用csiro数据分析，减产量为28%。

To take account of the differences ifpri fed both forecasts into its own computer , which describes how every agricultural region and , in some places , practically every farm , responds to changes in temperature and rainfall .

为了考量差异，ifpri把两种预测输入自己的计算机中，分析每个农业地区，有些地方分析几乎每一个农场在温度和雨量方面有什么变化。

Another new report , this one from ifpri , looks at how food policy is changing in response to higher food prices and the nutritional problems associated with them .

另一份来自国际粮食政策研究所的新报告审视了，为应对粮价上涨和随之而来的营养问题，粮食政策将如何作出改变。

When the international food policy research institute ( ifpri ) tried to work out the impacts of climate change on the main cereal crops , almost all its results suggested that yields in 2050 are likely to be lower than they were in 2000 , sometimes much lower .

当国际粮食政策研究所（ifpri）试图研究出气候变化对主要谷类作物的影响，几乎所有的结果都表明，2050年的产量可能低于2000年的产量，有时要低得多。

But south asia , the world 's most heavily populated region , looks vulnerable : ifpri forecasts a possible 50 % fall in its wheat yield in 2050 ( one-sixth of all the world 's wheat grows on the north indian plain ) .

世界人口最稠密的南亚地区在气象变化中极为脆弱：ifpri预测，该地区2050年小麦可能减产50%（全世界六分之一小麦产于印度平原北部）。
