本文开发了一个空间模型的水流域，允许地表水的分配和再利用的水是失去了。分析解决方案建议在空间上进行专业化生产-上游农民使用运河水，下游农民抽取上游流失的地下水。地下水是一种内源性“支持”。实证结果表明，当使用传统的保护技术，优化整个流域导致显着增加总产量，项目面积和用水量。与直觉相反的是，如果农民从传统灌溉技术转向现代灌溉技术，水的租金就会减少。
This paper develops a spatial model for a water basin that allows for surface water allocation and re-use of the water that is lost. The analytical solution suggests specialisation of production over space - upstream farmers use canal water and downstream farmers pump groundwater that is lost upstream. Groundwater emerges as an endogenous "backstop". The empirical results suggest that when traditional conservation technologies are used, optimisation over the entire basin leads to significant increases in aggregate output, project area and water use. Somewhat counter-intuitively, rents from water decrease if farmers switch from traditional to modern irrigation technology.
