他补充说:“一旦人们意识到有问题,他们往往就会去解决。在上世纪七八十年代的印度和中国,各地植被流失的情况严重。上世纪90年代,人们认识到了这一点,如今情况已经有所改善。人类的适应力令人难以置信。这就是我们在卫星数据中看到的情况。”
NASA网站则详细报道了中国和印度在耕种方面的经验:
Land area used to grow crops is comparable in China and India – more than 770,000 square miles – and has not changed much since the early 2000s. Yet these regions have greatly increased both their annual total green leaf area and their food production.
中国和印度用于种植农作物的土地面积相当,自本世纪初起一直均占77多万平方英里。然而,这些地区的年总叶面积和粮食产量都大大增加了。
This was achieved through multiple cropping practices, where a field is replanted to produce another harvest several times a year. Production of grains, vegetables, fruits and more have increased by about 35-40% since 2000 to feed their large populations.
这是通过复种轮作实现的,即每年多次重新种植土地获得多次收获。自2000年以来,粮食、蔬菜、水果等的产量增加了约35-40%,养活了庞大的人口。
看到这个好消息,全球网友都在为中国和印度点赞:
