Document Summary
Rainwater harvesting alleviates food problems and water problems. Correlation exists between lack of water storage, reduced food security, and poverty. Rwh used in india, uses tanks to collect water during monsoon season. Researchers suggest small-scale water solutions are the most cost-effective, efficient, and environmentally neutral: use soft path -large scale projects complimented by small-scale, decrentralized solutions. Tanks formed via construction of earthen banks across natural depressions, to stop and collect runoff. Tanks supports an area covering 61% of state, allowing growth of maize, sugar cane, chili peppers, rice. Provides economic, sociocultural and ecological services (flood control, nutrient and waste removal, provision of avian habitat, increased biodiversity: current state. Rwh started in 150 bc, stopped during green revolution in late. 1960s, because diesel and electric pump-set technology developed. More use, same amount of harvesting, lead to depletion. With decline in water, lead to decline in water management and tank maintenance: rwh and water portrait, future-
