Steering Committee 12 November Integrated Water Resource Management and its implications for the energy sector in Tajikistan PPCR Workshop on Climate Resilience and the Energy Sector 6-7 March 2012, Dushanbe

Steering Committee 12 November IWRM is a process which promotes the coordinated development and management of water, land and related resources, in order to maximize the resultant economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems (Dublin 1992, GWP) Ecological integrity Economic growth Social equity Sustainability

Steering Committee 12 November IWRM guiding principles  Consider all water uses jointly and balance the effect on each other  Manage jointly water quality and quantity  Public Participation in all phases from planning to implementation  Decision making on the lowest appropriate level  Women play an important role  Basins/hydrological boundaries as management areas  Flexible/adaptable to the specific needs

Steering Committee 12 November Agreement on IWRM for Tajikistan (April 2011)  Adoption of IWRM guiding principles (all sectors, joint quantity and quality management, participation, decision making at lowest adequate level)  Basin approach, hydraulic boundaries  Separation of functions between Policy making and regulatory Policy making and regulatory Operational Operational

Steering Committee 12 November 2007 Water and Energy  Becoming more of a topic of interest due to: relatively large consumption of energy by the water sector, e.g. relatively large consumption of energy by the water sector, e.g. In the UK 5% of all energy consumed (mainly for drinking water and sewerage systems)In the UK 5% of all energy consumed (mainly for drinking water and sewerage systems) In India 6% of the energy used is for pumping groundwater for irrigationIn India 6% of the energy used is for pumping groundwater for irrigation In Tajikistan this might well be even higher due to the large pumped systemsIn Tajikistan this might well be even higher due to the large pumped systems Increasing tendency to use irrigation for the growing of bio fuel crops Increasing tendency to use irrigation for the growing of bio fuel crops 7

Steering Committee 12 November Energy in Tajikistan  98% of the energy produced is through hydropower mainly generated by large dams and turbines  There is a large potential to increase the energy production from hydropower due to: suitable geography and geology suitable geography and geology large annual amount of internal renewable water resources (> 60 km 3 ) large annual amount of internal renewable water resources (> 60 km 3 )  Therefore in this presentation effects of large dams on various sub-sectors are evaluated  Given the uncertainty of the impact of climate change on the hydropower generation potential, it is advisable to re-evaluate reliance on hydropower only

Steering Committee 12 November 2007 Main interactions and climate change impacts Energy Disaster Management PPCR-Tajikistan March Inter-relations between energy & water & sanitation Impact on evaluated inter- relation Drier scenarioWetter scenario Impediment of sanitation due to waterlogging - +- Standing water bodies affect water quality and accumulate pollutants - -+/- Clusters of luxury accommodation might affect water quality - +/-

Steering Committee 12 November 2007 Conclusions  There are many interactions between reservoirs and various water sub-sectors  Some potential impact of climate change was considered using two extreme scenarios: drier and wetter  Due to the large variety of interactions it is not possible to identify which scenario leads to more positive or negative impacts and mitigation of one effect might lead to worsening of another 17
