Description:
The water-energy-food nexus is receiving increased attention worldwide due to climate change and rising population. According to a projection of the United Nations, the global population is expected to increase by a factor of 1.3 by 2050—from 7.2 billion to 9.6 billion—with corresponding demands for energy and food. Climate in the future is predicted to be warmer, with more frequent and intense rainfall as well as decreased rainfall reliability for agriculture in water-stressed regions. Rainwater harvesting (RWH) has been used to meet water demands for millennia. The historical context of RWH is still meaningful today and provides a more informed use of RWH as a climate change adaptation strategy. Our objective is to trace the development of RWH by comparing long-term use of hitis (water-spouts) in Nepal to five modern case studies from the U.S. in NY, FL, TX, IL, and CA.
