10 Who Is Water Rich and Who Is Poor? World Water Council 3 rd Water Forum Water Poverty Index (WPI) Among 147 countries Haiti Worst-Finland Best resources-access-capacity-use-environmental impact Why WPI: Because it makes the links between poverty, social deprivation, environmental integrity, water availability and Health enabling the policy makers and stakeholders to identify where problems exist and the appropriate measures to deal with their causes.. Is it only the amount ?

12 Problems Related To Water Resources in Turkey Quantity Quality Consequences: Depletion of groundwater level Loss of wetlands Polluted surface waters Polluted groundwater Salinization of coastal groundwaters Rapid and uncontrolled changes in land-use Rapid and uncontrolled growth Deficiencies ? Lack of advanced technologies? qualified personnel ? integrated approach? Institutional structure (vertical-lateral coordination)? policies based on knowledge of the phenomena? participation of the locals in planning and implementing? public awareness ?
