1 ADB TA 7599-TAJ Climate Resiliency for Natural Resources Investments Climate Risk Management in River Basins River basin approach to climate resiliency Climate hazards affecting river basins in Tajikistan Assets at risk in river basins Tajikistan Risk assessment methodology for river basins Pilot risk assessments in the Pyanj and Vakhsh river basins

2 ADB TA 7599-TAJ Climate Resiliency for Natural Resources Investments River Basin Approach to Climate Resiliency Objective Identify sustainable adaptations that will protect water dependent assets (communities, infrastructure, ecosystems) against unfavourable hydrological changes caused by climate change

3 ADB TA 7599-TAJ Climate Resiliency for Natural Resources Investments River Basins and Sub-Basins ADB TA 7599-TAJ Climate Resiliency for Natural Resources Investments Alexander, please use bright red colour for the sub-basin boundaries

4 ADB TA 7599-TAJ Climate Resiliency for Natural Resources Investments Potential Climate Changes and Hazards Affecting River Basins Climate ChangeClimate Hazard Higher temperature Increased melting of snow and glaciers ~ Glacier retreat ~ Glacier surging; glacial lake bursts ~ Increased summer flows initially ~ Reduced summer flows ultimately Longer growing season ~ Increased water demand for irrigation Increased demand for hydropower for air conditioning More rain Flash floods Reduced water demand for irrigation Less snow Less snowmelt Glacier retreat More evapo-transpiration Increased water demand for irrigation

6 ADB TA 7599-TAJ Climate Resiliency for Natural Resources Investments Principal Ecosystems in the Pyanj and Vakhsh River Basins

7 ADB TA 7599-TAJ Climate Resiliency for Natural Resources Investments Towns and Villages in the Pyanj and Vakhsh River Basins

8 ADB TA 7599-TAJ Climate Resiliency for Natural Resources Investments Main Roads in the Pyanj and Vakhsh River Basins

9 ADB TA 7599-TAJ Climate Resiliency for Natural Resources Investments Risk Assessment Methodology for River Basins Definition Impact Low (L)  No loss of life or houses  Minor damage to land and infrastructure  Minor temporary social and economic disruption  Responses include emergency services & minor remedial investments by village and District councils  Total damage less than US$ 100000 Medium (M)  No loss of life  Temporary loss of houses  Significant damage to land and infrastructure  Significant social and economic disruption  Responses include emergency services & substantial remedial investments by village and District councils with additional support from central Government  Total cost between US$ 100,000 and US$ 1000000 High (H)  Loss of life  Destruction of houses;  Destruction of to land and infrastructure  Serious social and economic disruption  Responses include national, provincial and district emergency services, international assistance, & major remedial investments by national Government with international assistance  Total cost greater than US$ 1000000 Frequency Low (L)  More than 10 years between events Medium (M)  5-10 years between events High (H)  Less than 5 years between events Lena, this table has already been translated for the Mid-Term Report

11 ADB TA 7599-TAJ Climate Resiliency for Natural Resources Investments Pilot Risk Assessments in the Pyanj and Vakhsh River Basins Based on hazard data and projections provided by: Committee for Emergency Situations and Civil Defence State Administration for Hydrometeorology FOCUS ACTED Government Ministries District Councils Community Leaders Field visits by the consultants

12 ADB TA 7599-TAJ Climate Resiliency for Natural Resources Investments Climate Change Risk Indices Risk Index 1 = Frequency (H, M, L) of Hazard and Impact (H, M, L) on Asset Risk Index 2 = % Probability ( >20%, 10-20%, <10%) of Hazard multiplied by % of total of Asset at risk in basin
