Zheng, Y., Ross, A., Villholth, K and Dillon, P. (eds) (2021) Managing Aquifer Recharge: A Showcase for Resilience and Sustainability. UNESCO-IAH Publication.
This is a 379 page 30MB book provides accounts of 28 MAR schemes from around the world by the implementers and operators. Many schemes are long-lived, demonstrating success in improving quantity and quality of water supplies and buffering them against drought and emergencies by communities from village to state, and trans-boundary level. A benefit-cost analysis shows that MAR offers a 50% reduction in costs compared to the best alternatives. When evaluated for its environmental and social sustainability using a basic qualitative technique specifically developed for this book, most schemes are found to be sustainable.
