Q1.In what way micro-watershed development projects help in water conservation in drought-prone and semi-arid regions of India?

Micro-watershed development integrates land, water, and vegetation management within small hydrological units. It is crucial for water conservation in India's drought-prone and semi-arid regions.

Water Conservation Mechanisms

• Rainwater harvesting: Structures like check dams, farm ponds, and gully plugs capture surface runoff.
• Groundwater recharge: Percolation tanks, contour bunding, and trenches facilitate infiltration, replenishing aquifers.
• Soil moisture conservation: Terracing, bunding, and afforestation reduce runoff, enhancing soil water retention.

Holistic Benefits for Drought-Prone Regions

• Mitigates soil erosion, improves soil fertility, and increases organic matter, fostering healthier ecosystems.
• Enhances agricultural productivity, fodder availability, and diversifies livelihoods.
• Ensures improved drinking water, reduces distress migration, and builds drought resilience.

These projects are vital for sustainable water management, promoting ecological balance, and enhancing climate resilience.
