在亚马逊河流域南部，一半以上的耕地每年种植两茬作物，这是一种被称为“双熟”的农业做法。气候变化，包括土地利用变化和当地气候之间的反馈，正在缩短亚马逊河流域南部历史雨季的范围，增加未来有害环境条件的风险，并对该地区目前实行的密集型DC农业构成威胁，在区域，国家甚至全球范围内产生潜在的负面影响。我们认为，在亚马逊河流域南部的未开发的森林和稀树草原的保护是由社会经济的理由支持，是在农业综合企业，地方政府和公众的最佳利益。
In southern Amazonia, more than half of all cropland is devoted to the production of two rainfed crops per year, an agricultural practice known as "double cropping" (DC). Climate change, including feedbacks between changes in land use and the local climate, is shortening the extent of the historical rainy season in southern Amazonia, increasing the risk of future detrimental environmental conditions, and posing a threat to the intensive DC agriculture that is currently practiced in that region, with potential negative consequences at regional, national, and even global scales. We argue that the conservation of undeveloped forests and savannas in southern Amazonia is supported by socioeconomic justifications and is in the best interests of agribusiness, local governments, and the public.
