Actual water situation

Population without access to safe drinking water

Global use of water Agriculture: 69% Industry: 23% Domestic use, drinking water, sanitation : 8%

Water Scarcity in 2025

Physical water scarcity: these countries have not sufficient water resources for the needs in 2025 Economic water scarcity: this group has enough water resources, but only with regulations (more supply than 1995, more than 25%) No physical water shortage: no water scarcity, less water supplies than 25% of 1995

Impacts of the global water shortage Relationship between food industry and global water No access to fresh water – rise in diseases Water plays an important role in trourism

Global water shortage – cross border problem The location of water resources – not follow pollical boundaries Most groundwater resources are shared by more than two states Cross boundary concerns risks – conflicts, pollution upstream, blocking of waterways or mismanagement of shared resources
