资料来源:博客文章:中国对空气污染的反应构成了对水的威胁

中国的空气污染控制行动计划具有雄心勃勃的目标 - 构成空气颗粒物和煤炭消费,但可能会给该国的供水带来意外的问题。

The Plan aims to reduce particulate matter in the North China Plain by 25 percent and reduce coal’s share of the national energy mix to 65 percent by 2017. One of the plan’s key recommendations is to replace coal with cleaner natural gas, including synthetic natural gas (SNG) converted from coal. Converting coal to natural gas, however, is an extremely water-intensive process. One cubic meter of SNG requires 6 to 10 liters (1.58-2.6 gallons) of freshwater to produce1. So in an attempt to control urban air pollution in the east, China might jeopardize its water supplies elsewhere.

使用WRI的渡槽水风险地图集,我们将这些认可的SNG植物的位置覆盖在我们的水应力图上,以评估潜在的水风险。批准的植物中有十一个,来自新疆省的八个,三座来自内蒙古的植物位于没有主要水库的集水区中。他们还面临季节性变异性的中等或高风险。因此,在干旱季节,由于缺乏供水的弹性,这些植物可能必须降低生产能力或体验暂时的停电
