Repeated droughts in agriculture have promoted intensive reliance upon groundwater resources, thereby exacerbating the already stressed groundwater reservoir situations all across the globe. This has also resulted in increased inequality among farmers by allowing those with better physical assets, such as borewells, to extract water at the cost of less affluent farmers. As a response, bore pool sharing collective arrangements were introduced in some parts of India, with the intention of slowing down the rate of groundwater depletion and helping improve the livelihoods of the worst affected farmers. Such arrangements work through promoting collective management of groundwater resources by providing critical and timely irrigation to rain-fed crops and through dis-incentivizing the cultivation of high water consuming crops. We investigate the impact of bore pool sharing programs on crop incomes and cropping patterns of the participating households in South India. A Probit-2SLS model and Propensity score matching method are used to evaluate the impact of such programs while controlling for self-selection biases. Results indicate that farmers' participation in bore pool sharing collectives is positively associated with their crop incomes. However, contrary to expectation, the share of high water-intensive-crops also increases with participation. In addition, share of water-intensive crops is higher for a collective group with a higher ratio of bore wells to number of participating households. Finally, farmers within the pool with multiple past failed bore well sinking attempts tend to extract more water, thereby threatening the sustainability of the groundwater as well as the livelihoods of the farming community.
