List two advantages associated with water harvesting at the community level.
Water harvesting is a strategy for holding water on the outside of the earth, to make it permeate under the ground in order to recharge groundwater. Two advantages associated with water harvesting at the community level are:
(i) Giving people control or command over their local water resources guarantees that mismanagement is decreased to a minimum level.
(ii) The water stored in the ground does not evaporate, gives moisture to vegetation over a wide territory, and is protected from pollution by human and animal waste. Hence over-exploitation of these resources is reduced.
