MAIN DUTY • Policy development for the protection, development and usage of water resources • And to coordinate water management issues both at national and international scale.
FIGHTING AGAINST CLIMATE CHANGE • Mitigation • Controlling, decreasing and absorption of the GHGs • Adaptation • The process of combatting against climate change impacts…
NEED FOR ADAPTATION • Even in the case of stopping all GHG emissions, climate will continue to change. • Poor people and poverty areas will mostly be affected. • Climate change is a development problem. To minimize economical, socialandenvironmentaleffectsandrisks ADAPTATION
HOW TO ADAPT? CLIMATE CHANGE IMPACTS ON WATER RESOURCES PROJECT
CLIMATE CHANGE IMPACTS ON WATER RESOURCES 25 River Basins Covering 783.562 km²
CLIMATE CHANGE IMPACTS ON WATER RESOURCES PROJECT • Started on 18th December 2013, the project aims • to determine the impacts of climate change scenarios on surface and underground water bodies • to identify the adaptation activities, implementation region based on river basin districts covering whole Turkey. • It is envisaged to be completed in July,2016.

Last Words.. • Climate Risk Management is vital in order to adapt. • Best adaptation measures are based on reliable impact and sectoral vulnerability analysis. • Climate change projections should be integrated at all levels of planning studies.
