Global warming threatens China's march to prosperity by cutting crops, shrinking rivers and unleashing more droughts and floods, says the government's latest assessment of climate change, projecting big shifts in how the nation feeds itself.
...Assuming no measures to counter global warming, grain output in the world's most populous nation could fall from 5 to 20 percent by 2050, depending on whether a "fertilisation effect" from more carbon dioxide in the air offsets losses, says the report.
Chinese grain crops are expected to see record harvests in spite of difficult conditions throughout the growing season.
Xinhua reports that current estimates from the Ministry of Agriculture put the total grain output of the Asian nation at more than 550 million metric tons, a 2.9 percent increase over the previous crop.
"This is a hard-won achievement for our country," Chen Xiaohua, vice minister of agriculture, told the news source.
The increase marks the eighth consecutive year of improving crop yields, a critical goal for a country with more than 1.3 billion people and rising standards of living.
