__NOTOC__
Rainwater harvesting refers to structures and methods of catching rainwater directly from roofs or indirectly through surface water runoff or spring catchments. It is then stored in underground (or above-ground) tanks or natural catchments for later use. For roof capture, any suitable roof surface — tiles, metal sheets, plastics, but not grass or palm leaf — can be used to intercept the flow of rainwater and provide a household with high-quality drinking water. Surface water capture can be through a dam, springbox, or groundwater recharge (includes in situ methods).
<font color="#000099" size="3">The reasons for using rainwater harvesting systems answer three questions:</font>
<font size="3">What</font>: Rainwater harvesting will improve water supply, food production, and ultimately food security.
<font size="3">Who</font>: Water insecure households or individuals in rural areas will benefit the most from rainwater harvesting systems.
<font size="3">How</font>: Since rainwater harvesting leads to water supply which leads to food security, this will greatly contribute to income generation.
