Improve water quality, wastewater treatment & safe reuse WHO – UN-HABITAT, 2018 • Water quality is worsening • >80% of wastewater discharged untreated • Mineral fertilizers grew 10x (1960) • Pesticide sales grew 35x ($ terms since1970) • Livestock 3x (1970) • Chemicals, medicines, hormones, micro-plastics … % of Safely Treated Households Wastewater A water-secure world www.iwmi.org
- 15. Increase water use efficiency & ensure freshwater supplies • Water stress: 2bn people & rising worldwide • Irrigation is 70% of global water withdrawals • Advances in agricultural water use efficiency key • Also ‘non-conventional’water, i.e., recycled wastewater, desalination, rainwater Water Stress A water-secure world www.iwmi.org Mekonnen and Hoekstra (2016)
