Phase IFoundation

Background

Overview

UPSC frequently examines environmental issues, ecosystem services, impacts of urbanization, and conservation efforts. Urban wetlands are critical for sustainable urban development, climate resilience, and public health, making their degradation a significant policy and governance concern.

Wetlands, including urban lakes, are vital ecosystems providing critical services like carbon sequestration, biodiversity support, and climate regulation. However, rapid and unplanned urbanization, coupled with encroachment and pollution, is leading to their widespread degradation and disappearance, posing significant environmental and public health challenges.

Facts & tables

Key facts

Ecological Importance

Wetlands cover ~6% of Earth's surface, store a disproportionately large share of carbon, and are crucial for biodiversity and climate regulation.

Threats

Rapid, unplanned urbanization, encroachment, and pollution are primary drivers of urban wetland degradation.

Consequences

Loss of urban wetlands erodes natural defenses against climate change, undermines public health, and threatens urban liveability.

Degradation State

Many urban wetlands are biologically dead or heavily eutrophic due to nutrient loading.
