What is rainwater harvesting?

The rain will collect in gutters that channel the water into downspouts and then into some sort of storage vessel.

What is rainwater harvesting and its importance?

The elimination of runoff can reduce contamination of surface water with pesticides, sediment, metals, and fertilizers. By reducing stormwater runoff, rainwater harvesting can reduce a storm's peak flow volume and velocity in local creeks, streams, and rivers, thereby reducing the potential for streambank erosion.

What are the causes of rainwater harvesting?

Large dams are the major source of water storage, and canals are the major distributory route. The former have caused large-scale community displacement and ecological havoc. The latter, large-scale degradation of land via soil salinisation. Groundwater resources have been heavily over-used.
