全球地下水恢复案例：干预措施如何逆转枯竭趋势

Full article and list of author affiliations: https://doi.org/10.1126/ science.adu1370 Scott Jasechko groundwater recovery episodes have exacerbated water scarcity elsewhere. Second, about half of the cases involve changes to policies or market conditions that reduced groundwater demands, such as the implementation and enforcement of groundwater withdrawal fees or restrictions on pumping. Third, many cases of groundwater recovery involve artificial groundwater recharge. This artificial recharge can be deliberate (e.g., diverting river water into intentionally leaky ponds) or incidental (e.g., leaky irrigation canals).
