Abstract

Groundwater exploitation has been instrumental in raising agricultural productivity andreducing rural poverty in South Asia, a region that accounts for nearly half of the globalgroundwater used for irrigation. Over the past three decades there has been an explosion ofprivate investment in borewells and mechanized pumps, which has allowed access togroundwater to be widely shared. But this profusion of drilling and pumping has also led toserious groundwater depletion. This essay explores South Asia’s groundwater dilemmathrough the lens of welfare economics, drawing on evidence from India and Pakistangleaned from a variety of sources ranging from agricultural censuses to specialized surveys.Policies to arrest groundwater depletion are also discussed.

南亚地下水的“福利”经济学

地下水开采在提高农业生产力和减少南亚农村贫困方面发挥了重要作用，该地区用于灌溉的地下水占全球的近一半。在过去的三十年里，在钻井和机械泵方面的私人投资呈爆炸式增长，这使得地下水资源得以广泛共享。但是这种大量的钻井和抽水也导致了严重的地下水枯竭。本文通过福利经济学的视角探讨了南亚的地下水困境，借鉴了来自印度和巴基斯坦的证据，这些证据来自农业人口普查和专业调查等各种来源。还讨论了阻止地下水枯竭的政策。
