Water Harvesting, Land and Water Use Planning for Sustainable Agriculture for the Western Part of the West Bengal

Abstract

The western district of West Bengal is notorious for its water scarcity and low crop output. Having visited the sites, interacting to the farmers and officials, and studying the proposed programs there is reason to appreciate the endeavor already put and likely to put forward towards eradication of drought from the region of Jangalmahal area. In consideration to adverse soil, land, geographical and geological several water harvesting, agriculture, and water management strategies that have been found to be effective in the region are offered and detailed. These are (i) check dams, ponds and recharging wells in jhor (drainage ditch) (ii) land grading and contour bunds (iii) sub-surface dam (iv) river-bank erosion measures (v)  non-conventional lined channel (vi) drip irrigation to orchards (vii) water ponds of low percolation and evaporation loss (viii) high seepage pond (ix) affluent pond (x) jallergola (water silo). With minimal environmental impact, successful implementation of these strategies could have a significant positive influence on drought management and agricultural development.
