Community-Based Water Resources Management Approaches for Hill and Mountain Ecosystems

This PDA aims to develop and demonstrate approaches for community-based water resources management for hill and mountain ecosystems, particularly water harvesting and utilization and soil management techniques.

Report Card

Completed in December 2008, this PDA

  • Identified and tested two farmer-friendly Multiple Use Water System , one in mid-hill and one in a mountain district
  • Established small and degraded watershed management technologies, rainwater collection systems, low-cost plastic ponds for collection of overflow/rain water, and drip irrigation systems
  • Tested bio-engineering technology, vermi-compost production technology, and bio-briquette production
  • Enhanced the capacity of ECARDS-Nepal and communities in using IWRM technologies.
  • Introduced market-oriented technologies to increase farmers' income

In Nepal, poor land management has led to increasing water problems. Soil erosion, soil degradation, and declining soil fertility caused by massive deforestation have increased surface runoff and contributed to the decrease of groundwater resources.

ADB’s Community Managed Irrigated Agriculture Sector Project (CMIASP), which began in 2006, implements farmer-managed irrigation system improvements and micro-irrigation. Under this project, water user associations (WUA) are being supported to take over ownership of irrigation systems and undertake operations and maintenance trainings. This PDA will introduce water resources management approaches to complement irrigation systems being develop under CMIASP.

Expected Outcome

  • Replicable approaches for community-based water resources management for hill and mountain ecosystems
  • Informed and empowered communities that are more involved in water resources management
