Journal Article
Hapa irrigation for promoting sustainable agricultural intensification
2021
Overview
This research examines the implications of rainwater harvesting structure hapa in the Bankura district of West Bengal, India. The paper finds that proper management and harvesting of surface and subsurface runoffs in hapas can facilitate groundwater recharge and increase both net irrigated area and moisture in soil leading to higher cropping intensity and yield in dryland areas. However, dissected plateau and residual hillocks can reduce irrigation efficiency of hapas. Although sprinkler or drip irrigation along with cultivation of drought and lateritic resilient, low moisture crop can help in coping up with geophysical and climatic vulnerability, appropriate crop diversification is also necessary. There is also a need for regular maintenance and desiltation of hapas. The water user groups should play an active role for this, especially for hapas in common land. Further, scientific guidance is necessary for designing appropriate structure of hapas in different geo-physical conditions.
