Rainwater
Harvesting....http://awm-solutions.iwmi.org/rainwater-harvesting.aspx....Many
areas that experience drought, also have excessive rainfall during the rainy
season.If the rain is saved, it can provide enough water to irrigate a
farmer's land throughout the dry season.Capturing this water and storing it
as surface water is called rainwater harvesting. By conserving the monsoon
rain, farmers can increase the area they irrigate, grow crops in the dry
season, support livestock and even recharge groundwater. This means better
food provision for their families and higher incomes.Stored rainwater also
provides families with water for their household needs.Ex-situ, or
decentralized, rainwater harvesting refers to any structures built to capture
rain. These could be ponds, tanks, or reservoirs and can be owned
individually or communally. They are all shapes and sizes, depending on the
amount of rainfall and the size of land available, the suitability of the
location and above all, the needs of the farmer.Some farmers manage to fund
the building of their own pond, others need financial help.There are other
practices which help conserve the rain as it falls in the field. Building
bunds or terraces increases the moisture retention of the soil and keeps
rainwater where it is needed, around the crops. This is known as in-situ
rainwater harvesting.
