2. Main Causes of Climate Change in Hunza and Gilgit-Baltistan

Climate change in Hunza and Gilgit-Baltistan is driven by a combination of global and local factors. Although the region contributes very little to global greenhouse gas emissions, it is among the most vulnerable to climate-related changes due to its high-altitude environment and fragile ecosystem. The following factors are the main causes behind the changing climate patterns in the region

• Global Warming: Rising global temperatures are causing rapid glacier melt and reduced snow cover in high mountain areas.
• Greenhouse Gas Emissions: Emissions from industrial activities worldwide trap heat in the atmosphere, directly affecting regional climate systems.
• Deforestation: Cutting trees for fuel and construction reduces natural carbon absorption and increases local temperatures.
• Population Growth and Urban Expansion: Increased human activity puts pressure on natural resources and disrupts ecosystems.
• Unsustainable Farming Practices: Overgrazing and improper land use degrade soil and reduce its ability to adapt to climate stress.
• Black Carbon Pollution: Smoke from vehicles, generators, and burning fuels settles on glaciers, accelerating ice melt.

3. Impact of Climate Change on the Ecosystem

Climate change is causing serious and long-lasting damage to the ecosystem of Hunza and Gilgit-Baltistan. The region’s natural balance—shaped over centuries by cold temperatures, glaciers, and predictable seasons—is now under threat. Changes in climate are affecting land, water, plants, animals, and human life simultaneously.

• Glacier Retreat: Rapid melting of glaciers is reducing long-term water storage and increasing the risk of glacial lake outburst floods (GLOFs).
• Water Scarcity: Irregular snowfall and faster ice melt are disrupting river flow, leading to water shortages during dry seasons.
• Loss of Biodiversity: Native plant and animal species are struggling to survive as habitats shrink and temperatures rise.
• Soil Degradation: Increased erosion, landslides, and floods are damaging fertile land and reducing agricultural productivity.
• Forest Decline: Changing weather patterns and human pressure are weakening forest ecosystems and reducing tree cover.
• Increased Natural Disasters: Floods, landslides, and avalanches are becoming more frequent and severe, threatening both ecosystems and communities.

4. Glacier Melting and Water Resources

Glaciers are the primary source of freshwater in Hunza and Gilgit-Baltistan, feeding rivers, streams, and irrigation channels that sustain agriculture and daily life. Climate change is accelerating glacier melting at an alarming rate, disturbing the natural water cycle of the region. While increased melting may cause short-term flooding, it poses severe long-term risks to water availability.

• Accelerated Glacier Melt: Rising temperatures are causing glaciers to melt faster than they can naturally regenerate.
• Glacial Lake Outburst Floods (GLOFs): Melting ice forms unstable glacial lakes that can burst suddenly, leading to destructive floods.
• Seasonal Water Imbalance: Excess water in summer and shortages in winter are disrupting agriculture and drinking water supply.
• Threat to Irrigation Systems: Traditional water channels (kuls) depend on steady glacier melt, which is becoming increasingly unreliable.
• Long-Term Water Scarcity: Continued glacier loss may reduce river flows permanently, affecting food security and hydropower potential.
• Impact on Downstream Areas: Changes in glacier-fed rivers affect not only Hunza but also downstream regions dependent on these water sources.

5. Effects on Biodiversity and Wildlife

Climate change is putting immense pressure on the rich biodiversity and fragile wildlife habitats of Hunza and Gilgit-Baltistan. This mountainous region supports a wide range of plant species and rare animals adapted to cold, high-altitude conditions. As temperatures rise and ecosystems shift, many species are struggling to survive.

• Habitat Loss: Melting glaciers, shrinking forests, and changing vegetation zones are reducing natural habitats for wildlife.
• Threat to Endangered Species: Species such as the snow leopard, ibex, and Marco Polo sheep face increased risks due to habitat disturbance and food scarcity.
• Changes in Plant Diversity: Native alpine plants are declining as invasive species move into warmer areas.
• Disrupted Food Chains: Climate-induced changes in vegetation and prey availability are affecting predator–prey balance.
• Altered Migration Patterns: Birds and animals are changing their migration and breeding cycles in response to temperature shifts.
• Icncreased Human–Wildlife Conflict: Wildlife moving closer to settlements in search of food and water leads to more conflicts with local communities.

6. Impact on Local Communities and Livelihoods

• Agricultural Losses: Irregular rainfall, shorter growing seasons, and extreme weather events are reducing crop yields.
• Water Shortages: Unstable glacier melt and reduced snowfall are limiting access to clean drinking and irrigation water.
• Damage to Infrastructure: Floods and landslides are destroying homes, roads, bridges, and irrigation channels.
• Threats to Livestock: Loss of grazing land and harsh weather conditions are affecting animal health and productivity.
• Economic Instability: Tourism, a key source of income, is impacted by natural disasters and environmental degradation.
• Forced Migration: Some families are compelled to relocate due to repeated disasters and loss of livelihood resources.
