Improved rainwater management

Jump to: navigation, search
Description: Improved rainwater management assumes a decrease in the evaporative losses from rainfed agriculture and the creation of small scale reservoirs to harvest rainwater during the wet period and use it during a dryer period. Both measures lead to more efficient use of water and increased yields on rainfed fields.

Effects of this policy intervention on components

Component: Water

Effect : Improved rainwater management will lead to more efficient use of rainwater over the year and therefore a better fullfillment of crop water requirements. Further it will lead to more efficient use of the soil moisture because of a decrease in evaporative losses from bare soil. Both measures lead to increased yields of rainfed agriculture.
