The most drastic adaptation would be taking fields out of production completely.

最极端的应对措施将是让田地完全停产。

Today, Vietnam is preparing to take nearly 250,000 acres of land in the Mekong Delta, its rice bowl, out of production.

如今，越南正准备让有越南“饭碗”之称的湄公河三角洲的近25万英亩土地停产。

That soil loss reduces global crop yields by as much as if we took a California-sized swath of farmland out of production every decade.

土壤流失减少了全球农作物产量，相当於每十年荒废一块加州大小的农地。
