Vision Preparatory Phase For Koshi Basin by ICIMOD and Partners Fully Fledged Programme 2. Situation Analysis 7. Monitoring and Evaluation 5. Proposal Development e.g. ESPA Assess Progress Revise Programme Characteristics of the Koshi, Key Issues, & Gaps 6. Implementation 3. Programme Choice of Programme Plan Priorities identified 4. Draft Programme Plan Stakeholder and Partner Approval Preparatory phase: activities • Develop partnerships • Workshops and field mission • Identify key issues and areas for collaboration – – – – Glaciers, glacial lakes, water resources & hazards; Biodiversity; Land use and land cover change; Socio-economic development and regional development. • Collate previous and on-going work in the Koshi Basin • Develop programme in the Koshi basin • Explore funding opportunities, e.g. UK-funded ESPA: wider partnerships, IIT-Delhi Key Issues – (1) glaciers/water/storage/hazards No. of Glacial lakes in Koshi (Nepal) 2001 2009 1062 599 Change between 2001 and 2009 Nos.

Draft Conceptual Framework Draft Programme Work Areas 1. Coordination, integration and data management 2. Climatic, cryospheric and hydrological characterization, monitoring and modeling 3. Basin wide socio-economic sectoral analysis of water and land use: baseline and future projections 4. Water related hazard assessment and management; including sediments, GLOF, flash floods, landslide and drought 5. Biodiversity and ecosystem services; status characterization and degradation assessment 6. Evaluation of different water storage components (natural and man-made) 7. Water availability and efficiency in the agricultural sector 8. Adaptation and livelihood strategy development for impacts from climatic and socio-economic drivers 9. Development of integrated policies and strategies for governments, international donor community, NGOs and CBOs Next Steps • Conclusion of preparatory phase: – – – – Final workshop Spring 2011 Joint reports Koshi basin information system Koshi programme finalised • Partnership Development: – Consolidation of Chinese and Nepali partners – Development of new partners, especially India • Exploration of funding opportunities: – UK Environmental Services for Poverty Alleviation – Research Consortium developed, Write-Shop December 2010 • Third Pole Environment: – Koshi River Basin programme will be a beneficiary and contributor Thank you
