In what way micro-watershed development projects help in water conservation in drought-prone and semi-arid regions of India?
Approach · directive: “in what way”
What it asks · Explain how treating small drainage units captures rainfall and raises soil moisture and groundwater in dry regions, and the conditions for success.
It asks 3 things — answer each
- Explain in what way micro-watershed projects conserve water: ridge-to-valley treatment and its structures
- Explain the gains in groundwater, soil moisture and livelihoods in drought-prone and semi-arid regions, with examples
- Note the conditions for success and the limits
Open with · In drought-prone and semi-arid India rain falls in a few intense spells and runs off; a micro-watershed project treats one small drainage unit from ridge to valley to store it where it falls.
Cover
- Concept: ridge-to-valley treatment of a small drainage unit so rain is slowed, spread and stored.
- Structures: contour trenches and plantation on ridges; field bunds and terraces on slopes; gully plugs, check dams, farm ponds and percolation tanks on drainage lines.
- Water gains: higher water tables, revived wells, drinking water in summer, protective irrigation.
- Livelihoods: second crop, fodder, livestock, less distress migration; Ralegan Siddhi, Hiware Bazar; WDC-PMKSY 1.0 reports 70% income rise and 3 m groundwater gain.
- People's models: Neeru-Meeru (Andhra Pradesh), Arvary Pani Sansad (Alwar, Rajasthan), Haryali (NCERT).
- Conditions: community institutions, equity, maintenance funds, crop-water budgets and borewell limits.
Close with · WDC-PMKSY 2.0 now runs 1,220 projects over 50 lakh hectares; its success will rest less on structures than on villages that budget their water.

In drought-prone and semi-arid India, rain falls in a few intense spells and runs off before it can soak in. A micro-watershed project treats one small drainage unit from ridge to valley, so rain is slowed, spread and stored where it falls.
How it conserves water
- Ridge: trenches, plantation
- Slopes: bunds, terraces
- Drainage line: gully plugs, check dams
- Storage: ponds, percolation tanks
- Recharge
- Ridge treatment: contour trenches and plantations on upper slopes slow runoff so water sinks in before it gathers speed.
- Field treatment: field bunds, terraces, vegetative barriers and mulching keep moisture and topsoil on farmland.
- Drainage-line treatment: gully plugs, check dams, percolation tanks and farm ponds trap stream flow and recharge aquifers.
- Vegetation: regenerated pasture and tree cover cut evaporation and bind soil.
Gains in dry regions
- Water security: revived wells give drinking water through summer and protective irrigation at critical crop stages.
- Livelihoods: a second crop, fodder and livestock cut distress migration, as Ralegan Siddhi and Hiware Bazar show.
- Measured results: since then, the Rural Development Ministry has reported that WDC-PMKSY 1.0 raised farmers' incomes by 70% and groundwater tables by about 3 metres.
- People's models: NCERT cites Neeru-Meeru (Andhra Pradesh) and Arvary Pani Sansad (Alwar, Rajasthan), which built johads, check dams and percolation tanks through people's participation.
Conditions for success
- Community ownership: watershed committees and user groups that plan, share costs and maintain structures, with equity for the landless and women.
- Guarding the gains: crop-water budgets and borewell limits, or recharge is pumped away; maintenance needs funds, not only construction.
(Since then) WDC-PMKSY 2.0 runs 1,220 projects over 50 lakh hectares; its success will rest less on structures than on villages that budget their water.
