ABSTRACT

This paper examines the inequity in irrigation distribution in India using a variant of Theil’s entropy measure for the period 1995–2010. The analysis reveals that the level of inequity in irrigation distribution has increased over time. Inequity has declined in canal, tank and well-irrigated systems and increased in the tube well-irrigated system. Decomposition analysis revealed that regional disparities have declined in all sources of irrigation except for tube wells. The role of property rights to groundwater, groundwater markets, energy pricing policy and competitive deepening of wells in worsening the inequity in access to groundwater resources is also discussed.

摘要

本文使用 1995 年至 2010 年期间泰尔熵测量的变体来检验印度灌溉分配的不公平性。分析表明，灌溉分配的不公平程度随着时间的推移而增加。渠道、水箱和良好灌溉系统的不公平性有所下降，而管状良好灌溉系统的不公平性有所增加。分解分析表明，除管井外，所有灌溉来源的区域差异均有所下降。还讨论了地下水产权、地下水市场、能源定价政策和井的竞争性深化在加剧获取地下水资源的不平等方面的作用。
