Background

Overview

UPSC frequently examines the environmental challenges faced by ecologically sensitive regions like the Himalayas, the impact of development projects, disaster management, and the policy frameworks for their sustainable development and conservation.

The Himalayas, a young and tectonically active mountain range, are recognized as one of the world's most fragile and ecologically sensitive regions, crucial for biodiversity, water security, and climate regulation in South Asia.

Key facts

Geological Instability

Young fold mountains, prone to earthquakes, landslides, and flash floods due to tectonic activity and steep slopes.

Biodiversity Hotspot

Home to unique flora and fauna, including many endemic and endangered species, making it a global biodiversity hotspot.

Water Tower of Asia

Source of major perennial rivers like the Ganga, Indus, and Brahmaputra, vital for the livelihoods of millions downstream.

Climate Change Vulnerability

Highly susceptible to impacts of global warming, including glacial melt, altered precipitation patterns, and extreme weather events.
