1. Empowered Lives. Resilient Nations. AN ECONOMIC ANALYSIS ADAPTATION TO CLIMATE INDUCED FLOODS IN KOSHI BASIN OF TERAI NEPAL Parashu Ram Adhikari, DhanejThapa, KheemaSubedi,BasantaPaudel NEPAL Bangkok, ECCA Training, September 1, 2017

2. PROJECT BACKGROUND Climate vulnerable country, High dependence on environmental resources Erratic nature of the monsoon rainfall pattern and climate extreme events ,increased mean annual precipitation; with decreased of rainy days with increased number of high-intensity rainfall events. Flood incidence increased in Nepalese context Floods in Koshi: Koshi river basin, which carries highest siltation among Nepali river, damaging million of hectare of arable land.

3. OBJECTIVES Objectives The overall objective is to assess climate induced flood risk and evaluate adaptations options suitable for agriculture resilience in Koshi basin of Terai Nepal. • Specific Objectives • To estimate physical impacts of climate induced flood risk in Koshi river basin area of Terai Nepal; • To calculate economic cost of floods in agriculture production; • To identify and compare economic cost and benefit of different adaptation options; and • To rank different flood adaptation options based on obtained NPV.

4. METHODOLOGY • Deductive and Inductive Approach, • Use of Flood and Crop yield simulation Studies • GIS based mapping for area decline with floods in different years • Different Scenario Analysis With flood hazards without CC and increased floods hazards in CC context. • Flood model/hydrological models • Precipitation: Seasonal variability, inter-annual variation, Recurrence of floods and intensity and frequency • Past extreme events, its increased intensity, frequency and recurrence in recent years. • Satellite images captured in different in flood years

5. METHODOLOGY With flood hazards without CC and increased floods hazards in CC context. • Flood model/hydrological models • Precipitation: Seasonal variability, inter-annual variation, Recurrence of floods and intensity and frequency • Past extreme events, its increased intensity, frequency and recurrence in recent years. • Satellite images captured in different in flood years Losses in agriculture production with flood hazards and with increased flood hazards due climate change. • Land loss • Production decline, farming system, Agriculture productivity, production trend, • Recardian model for impact on agriculture production(decline of net revenue)

6. METHODOLOGY • Losses in agriculture production with flood hazards and with increased flood hazards due climate change. • Land loss • Production decline, farming system, Agriculture productivity, production trend, • Recardian model for impact on agriculture production(decline of net revenue) • Cost of and Benefit of Adaptation options. • Cost of agriculture Adaptation; Submergence-tolerant rice varieties and river-belt farming (with floods) • Flood protection: Riperian Plantation(without floods
