Far-reaching impact of melting Himalayan glaciers

Published on 02 Feb 2025

• Reduced Runoff: Melting glaciers contribute to increased river runoff initially, but as glaciers shrink, the overall runoff may decline, affecting water supply for downstream regions.

• Variable Hydropower Potential: Glacial meltwater is crucial for hydropower generation in the region. Changes in glacial melt patterns can impact the reliability and predictability of hydropower potential.

• Agriculture: Many regions in India depend on glacial melt water for irrigation. Changes in water availability can impact agricultural practices and productivity.

• Biodiversity: Glacial meltwater contributes to river ecosystems. Changes in water flow and temperature can impact aquatic biodiversity, affecting fish species and other aquatic life.

• Disaster risks: Melting glaciers can lead to the formation of glacial lakes posing a threat as glacial lake outbursts.

• Sea level rise and flooding: Glacial melt contributes to river discharge into the oceans, indirectly affecting sea level.

• Tourism: Melting glaciers can alter the landscape, impacting tourism. Receding glaciers may affect the aesthetic appeal and attraction of certain tourist destinations.

• Geopolitical issues: Shared river basins originating from the Himalayas can lead to geopolitical tensions among countries that depend on these water resources.

• Migration and livelihoods: Changes in water availability and agriculture can lead to shifts in livelihood patterns, potentially causing migration and impacting local economies.

• Cultural and spiritual significance: Glaciers hold cultural and spiritual significance in many Himalayan communities. Changes in glaciers can affect local religious practices and beliefs.
