  1. Disaster Risk Reduction and Climate Change Adaptation in Koshi River Basin Nepal LaxmiDevkota Principal Investigator NDRI

  2. Project Brief • Funded by: • Climate and Development Knowledge Network (CDKN) and • Global Change SysTem for Analysis, Research and Training (START) • Team: PI: Dr. LaxmiDevkota CI: Dr. Manjeshowri Singh CI: Dr. Sunil BabuShrestha CI: Dr. Rijan B. Kayastha RA: 3 Persons Research Students: 5 Persons Steering Committee: To Guide the Team

  3. Introduction: Koshi River Basin • Koshi River : One of the largest tributaries of the Ganges River System • Trans-boundary river: China, Nepal and India • Drains 29,400 km2 in China and 30,700 km2 in Nepal (ICIMOD, 2008)

  4. Introduction: Koshi River Basin • South-west monsoon greatly influences the hydrology of the Koshi River Basin • High sediment laden river • Shifting nature of main river course • Flooding incidences • Glacial Lakes: 599, covering 26 sq. km. (ICIMOD, 2011)

  5. Rationale • Water induced disasters: • Devastating Flood events: Recent 18th August 2008; 16 GLOF events • Rapid development including urbanizations in the lower part of the basin: • the communities and infrastructure more vulnerable to the increasing flood hazards including the risks of GLOFs • Koshi High Dam: • Flood control, Irrigation and Hydropower generation • Climate Change: • Impact the hydrological regime

  6. Objectives of the Project Overall Objective: To assess the impact of climate change on current and future development in Koshi River Basin Specific objectives: • Advancing knowledge on climate change impact on water resources • Assessment of flood risks in the context of climate change • Revisiting the design standards/values • Contributing to policy formulation process • Awareness building of stakeholders including local communities and training of new generation

  16. Outputs, Outcomes and Impacts Expected Impacts : • Reduction on climate related disasters and losses in the Koshi River Basin • Formulation of better policy related to DRR and CCA Specific Outputs: • Models to assess the climate change impacts • Hazard, Vulnerability and Risk Maps • Policy recommendations at national and community levels for DRR and CCA • Capacity building of young researchers • Publication of peer-reviewed journal articles • Awareness Buildings of the concerned stakeholders
