Phase IFoundation

Background

Overview

Addresses a critical environmental challenge impacting water security, livelihoods, and the sustainability of fragile ecosystems. Understanding its drivers is essential for effective policy formulation and sustainable resource management, particularly in ecologically sensitive areas like the Himalayas.

Groundwater depletion refers to the long-term decline in the water table due to unsustainable extraction or reduced recharge. In mountain regions, this often manifests as drying up of natural springs and traditional water sources, exacerbated by both natural and anthropogenic factors.

Phase IIStatic core

Facts & tables

Key facts

Definition

Reduction in underground water reserves, leading to weakening and drying of natural springs (dharas) and aquifers.

Natural Drivers

Frequent forest fires (destroying vegetation, drying soil), climate change (irregular rains, reduced snowfall, rapid surface run-off).

Anthropogenic Drivers

Road construction, urbanisation, rising tourism damaging natural water channels and recharge zones.

Impact

Acute water shortages for communities, affecting traditional water systems like Naulas.
