Since independence, India has emerged as the world’s largest groundwater economy, with annual groundwater use increasing from less than 50 BCM in the 1950s to over 230 BCM today. While this groundwater boom has been the bedrock of India’s agricultural growth, it has also created formidable challe...
This article investigates water security in Nepal from the perspective of the water-energy-agriculture (food) nexus, focusing on pathways to water security that originate in actions and policies related to other sectors. It identifies promoting development of Nepal’s hydropower potential to provi...
