Himalayan communities are relying on centuries-old water solutions in the face of climate change

🗞️ Driving the news: Across the Himalayas, communities are combining centuries-old water management practices with new technologies to cope with increasingly unpredictable floods, droughts and glacier melt
• From restoring ancient underground water networks in Nepal to building artificial glaciers in Ladakh, local initiatives are helping people adapt to a rapidly changing mountain environment

🔭 The context: The Hindu Kush-Himalayan region is warming rapidly, with glacier mass loss accelerating and water supplies becoming less predictable
• In Nepal, communities are restoring traditional stone spouts and underground terracotta canals that capture monsoon rainfall and recharge groundwater
• In the Limi Valley, local activist Tashi Lhazom helped scientists identify a previously overlooked flood mechanism linked to thawing permafrost, now recognised as a risk known as Small Alpine Lake Outbursts (SALOs)
• In Ladakh, engineer and climate activist Sonam Wangchuk has developed artificial ice stupas that store winter water for use during the spring planting season
• Automated systems now help prevent their pipes from freezing

🌍 Why it matters for the planet: Glacier loss and changing rainfall patterns threaten water security, ecosystems and livelihoods across the Himalayas, with consequences for downstream populations throughout Asia
• These community-led solutions demonstrate how traditional knowledge, scientific research and locally adapted technology can strengthen resilience, although they cannot replace the need to reduce global greenhouse gas emissions

⏭️ What’s next: The priorities include restoring vulnerable water systems, mapping emerging flood hazards, improving early warning and supporting communities that may need to relocate
• The article reports that 160 ice stupas have been built or supported across six countries, while Nepal is working to resettle thousands of people from high-risk areas
• The long-term effectiveness of these measures would depend on continued investment and the pace of glacier loss

💬 One quote: “The frozen water banks we know are melting, and that means flooding that can sweep an entire village away within a fraction of a second,” - Tashi Lhazom, a climate activist from Nepal’s Limi Valley

📈 One stat: 160 ice stupas — the number built or supported across Ladakh, Nepal, Mongolia, Kyrgyzstan, Chile and Pakistan
