The effective management of land and water resources will drastically reduce the human miseries. Explain.

India supports 18 percent of the world's population on 2.4 percent of its land with 4 percent of its freshwater. Nearly 30 percent of that land is degraded (ISRO Desertification Atlas), and many groundwater blocks are over-exploited. Mismanaged land and water translate directly into human misery: drought, flood, hunger, distress migration and conflict. Their effective management is therefore a humanitarian imperative, not merely an environmental one.

How effective management reduces misery

• Watershed development: ridge-to-valley treatment recharges aquifers and stabilises yields; Ralegan Siddhi and Hiware Bazar turned drought-hit villages into surplus economies and reversed out-migration.
• Soil conservation: contour bunding, mulching and agroforestry check erosion, sustaining productivity and easing rural poverty and malnutrition.
• Water-use efficiency: micro-irrigation under Per Drop More Crop raises incomes while cutting water draft; crop diversification away from water-guzzlers reduces drought vulnerability in Punjab and Marathwada.
• Flood moderation: floodplain zoning, wetland restoration and catchment afforestation temper the floods that annually displace lakhs in the Brahmaputra and Kosi basins.
• Harvesting and employment: rainwater harvesting and MGNREGA water assets such as farm ponds and check dams provide protective irrigation and wage security in dry years, scaled nationally by the Jal Shakti Abhiyan.
• Social dividends: restored commons cut women's drudgery in fetching water, fuel and fodder, freeing time for education and livelihoods.

Land and water are the primary capital of the poor. Managing them conjunctively, through integrated watershed programmes, basin-level planning and community stewardship of the kind seen in Rajasthan's johad revival, attacks the roots of hunger, displacement and conflict rather than treating their symptoms, and thereby drastically reduces human misery.
