Building the Evidence for Nature-Based Flood Resilience in Nepal 
 

Across Nepal’s rivers and floodplains, communities are turning to nature to protect their homes and livelihoods. Building on the lessons from projects implemented across multiple river basins, we have gathered evidences of how working with nature can reduce flood risks while strengthening local livelihoods and community resilience. Through field visits and direct engagement with communities, we gained valuable, firsthand insights into what works on the ground. 

What We Observed on the Ground 

Mountain EbA Program in Panchase Region: 
In the hills of Panchase, communities are conserving ponds and forests to protect water sources and reduce siltation. 

• Pond conservation improves groundwater infiltration 

• Reforestation and forest protection help regulate water flow and prevent erosion 

These measures are restoring ecosystems while making communities more resilient to climate change. 

Far Western Nepal: Flood Responsive Farming
Along flood-prone rivers, local communities are planting sugarcane and wild sugarcane (Khar Kans) to stabilize riverbanks. 

• Strengthens riverbanks and reduces erosion 

• Makes plantation possible on sandy riverbeds, creating new livelihood opportunities 

This simple, nature-based approach delivers both protection and prosperity. 

Bamboo Biodykes in Western Nepal 
In collaboration with Practical Action, bamboo biodykes have been introduced as a natural alternative to concrete embankments. 

• Reinforces riverbank slopes 

• Slows floodwaters 

• Protects agricultural land and homes 

• Uses locally available sustainable materials 

These biodykes demonstrate how low-cost, community-led solutions can effectively manage flood risks. 

Key Learnings 

Our observations confirmed that Nature-based Solutions are practical, scalable, and deeply impactful. They: 

• Reduce flood risk 

• Restore ecosystems 

• Strengthen livelihoods 

• Empower local communities 

The insights gained from these case studies have strongly reinforced the project’s objectives and highlighted the critical role of nature in building climate-resilient futures for Nepal.
