Describe impact of human beings on water resources.

Question

Ghissu Editorial · Accepted Answer

Human beings affect water resources through groundwater over-extraction, industrial and agricultural pollution, large dams that alter river flows, and rising urban demand. These reduce water availability and quality, harm ecosystems and health, and cause displacement, as with the Polavaram project displacing over 1 lakh families.

**Introduction**

Water resources face severe pressure from human activities like urbanisation, agriculture, and infrastructure projects, threatening availability and quality, notably in ==Andhra Pradesh==. Rapid population growth and economic development further intensify demand, exacerbating stress on water systems.

**Human Activities Affecting Water Resources**

2. **Pollution from Industrial and Agricultural Sources**: Discharge of untreated industrial effluents and pesticide-laden agricultural runoff contaminates surface and groundwater, harming aquatic ecosystems. The Central Pollution Control Board reports rising pollution levels in key river basins, worsening water quality.

**Consequences on Water Availability and Quality**

1. **Reduced Water Availability**: Unsustainable groundwater use and river flow diversion reduce freshwater access, causing scarcity in rural and urban ==Andhra Pradesh==. The India Water Resources Information System highlights declining per capita water availability in the region.  
2. **Deterioration of Water Quality**: Pollutants increase contamination, making water unsafe for drinking and irrigation, impacting health and agriculture. The National Rural Drinking Water Programme identifies contamination as a major cause of unsafe water supply in many villages.

**Socio-Economic and Environmental Implications**

1. **Agricultural Stress and Livelihood Loss**: Water scarcity lowers crop yields in ==Rayalaseema and drought-prone districts==, increasing rural distress and migration. The State Planning Commission notes that declining water availability threatens food security and farmer incomes.  
2. **Social Displacement and Conflict**: The ==Polavaram Project⟦1⟧== displaces over 1 lakh families, causing social upheaval and rehabilitation challenges. The Supreme Court has emphasised the need for fair compensation and resettlement to mitigate such impacts.

**Conclusion**

Addressing these impacts requires integrated water resources management⟦2⟧ and sustainable practices, as promoted by the National Water Mission and implemented in ==Andhra Pradesh==, to ensure water security and meet SDG 6. Strengthening pollution control and groundwater regulation is also vital for long-term sustainability.
