Phase IFoundation

Background

Overview

This concept is critical for understanding India's water crisis, agricultural sustainability, urban planning challenges, environmental governance, disaster management (especially urban floods), and the effectiveness of government welfare and infrastructure schemes. It touches upon resource management, ecological conservation, and socio-economic development.

Traditional water bodies like irrigation tanks, ponds, and rivers, crucial for agricultural irrigation, groundwater recharge, and urban water supply, are increasingly threatened by human activities. Their degradation impacts water security, ecological balance, and urban resilience to natural disasters.

Facts & tables

Key facts

Causes of Degradation

Siltation, encroachment (of water bodies and feeder channels), and pollution (sewage, garbage dumping) are primary drivers of degradation.

Consequences

Reduced water storage capacity, increased vulnerability to urban flooding, groundwater depletion, and contamination rendering water unusable for drinking or irrigation.

Policy and Scheme Responses

Government initiatives like MGNREGS (for desilting) and AMRUT 2.0 (for water body rejuvenation and sewerage infrastructure) are deployed for restoration.

Governance and Legal Aspects

Local administration (District Collector, Municipal Corporations), judicial intervention (High Courts), and community/NGO activism play crucial roles in protection and restoration efforts.
