Irrigated agriculture is placing increasing pressure on finite freshwater resources, especially in developing countries, where water extraction is often unregulated, un-priced and even subsidized. To shift agriculture to a more sustainable use of water without harming the food security and livelihoods of hundreds of millions of smallholders, substantial improvements of water use efficiency will be required. Here, we use detailed hydroclimatic and agricultural data to estimate the potential for the widespread adoption of efficient irrigation technologies to halt the depletion of India's groundwater resources. Even though we find substantial technical potential for reversing water table declines, we show that the …

The recognition of the limits of resources is almost as old as the realization that our planet is a sphere leading to concerns about sustainable resources management. Water resources in particular receive growing attention given its uneven distribution in many parts of the world. Engineering solutions to address water management challenges played significant roles in the past in areas such as access to clean water and sanitation, providing water for irrigation, offering protection against floods, allowing power generation, etc. Despite their proven benefits, engineering solutions are receiving increasing criticism due to their negative environmental and societal impacts and the high …
