suggested measures on irrigation
Answers
Answer:
Some measures to improve water storage and irrigation system to make its judicious use under depleting scenario are:
1. Micro Irrigation encompassing drip and sprinkler irrigation results in efficient deployment of inputs like water, electricity, fertilizers, labour; increase in crop productivity; irrigation of additional area under crop; and bringing under cultivation water deficient, cultivable wasteland and undulating land areas due to ease of irrigation.
2. Special emphasis on watershed management programmes to address the issues related to wild runoff, conservation of soil and water, employing the runoff water, the percolation of rainwater, and rehabilitation of the wasteland is imperative.
3. Rainwater harvesting to collect and store rainwater at surface or in sub-surface aquifers so that it can’t be lost as surface run-off.
4. There is need to adopt methods like “Dong Bundh System” deploying conventional methods. It is a traditional water conservation and management system in which construction is done by locally available material and the channelized water is directed to the villages and agricultural field to ensure availability of drinking and irrigation water.
5. Transfer of water from water surplus basins to water deficit basins through inter-linking of rivers is envisaged.
6. Canals, infiltration basins, water bodies, irrigation furrows, sprinkler systems, injection wells should be used to redirect water across the land surface to recharge groundwater artificially.
7. Rehabilitation of dams on the basis of their assessed needs to ensure water security.
Water resource management efforts, at large, require focus on water conservation, rainwater harvesting, renovation of traditional and other water bodies or tanks, reuse and recharge of bore wells, watershed development and intensive afforestation.
