6. WP 5: Socio-Economic Impacts The Cost of Not Acting Total GDP Lost: 11 B$/y Cost of: CSP/Desalination 1.5 - 0.3 €/m³ Savings Irrigation0.2 €/m³ Savings Domestic0.4 €/m³ Savings Industrial0.2 €/m³ Wastewater Re-use0.1 €/m³ Not-Acting 0.6 - 1.8 €/m³

7. WP 5: Socio-Economic Impacts Urbanisation versus Rural Development Urban settlements with over 5000 inhabitants Recent analysis by World Bank, WWF etc. state that seawater desalination is no sustainable solution  contradiction to literature

8. WP 5: Socio-Economic Impacts Conclusions  Cost perspective of CSP desalination is affordable (< 0.4 €/m³), while that of conventional desalination is not  Efficiency enhancement and desalination are less expensive than not acting  „Solar“ water can avoid dependency on „virtual“ water  CSP desalination can create arable land for rural and urban development  CSP desalination is a totally over-looked solution to the MENA water crisis
