Description

Landless, small holders and other poors supplement their livelihood and adapt to climate change by grazing, stall feeding with crop residues and fodder cultivated under rainfed and irrigated conditions. Improving productivity by conserving rainfall, ground water recharging, harvesting and recycling of rainwater especially in degraded open access or shared land with community participation was quite successful over a wide range of precipitation and ecological situations. Various types of trenches, bunding, vegetative barriers, gully plugs, ponds, check dams, land slides and mine spoils stabilization etc. retained more soil moisture, seeds, vegetative propagules etc. in situ and prevented soil erosion. It regenerated and enhanced biomass production of grasses, other forages, crop residues and environmental externalities. It reduced socially undesirable seasonal migration of herders by 35-100%, number of goats, dependency on open or common access resources and increased bovine population, stall feeding and milk productivity. Limited irrigation with harvested and recharged rainwater led to farm diversification, more availability of crop residues and better income. Climate change has reduced number of rainy days, increased intensity and frequency of run off producing events and can be converted into still better opportunities of adaptation by rain water harvesting.

Rainwater Harvesting and Its Impact on Farming Systems
