The vast semi-arid Southern peninsular region of India is irrigated using a traditional surface water infrastructure called Tank Cascade Systems (TCS). The TCS is a common-property resource that was constructed about 2000 years ago and has been managed since then for generations using public-participatory approaches. Furthermore, the application of...
