CLEAN WATER AND SANITION

Too many people still lack access to safely managed water supplies and sanitation facilities. Water scarcity, flooding and lack of proper wastewater management also hinder social and economic development. Increasing water efficiency and improving water management are critical to balancing the competing and growing water demands from various sectors and users.

• In 2015, 29 per cent of the global population lacked safely managed drinking water supplies, and 61 per cent were without safely managed sanitation services. In 2015, 892 million people continued to practise open defecation.
• In 2015, only 27 per cent of the population in LDCs had basic handwashing facilities.
• Preliminary estimates from household data of 79 mostly high- and high-middle-income countries (excluding much of Africa and Asia) suggest that 59 per cent of all domestic wastewater is safely treated.
• In 22 countries, mostly in the Northern Africa and Western Asia region and in the Central and Southern Asia region, the water stress level is above 70 per cent, indicating the strong probability of future water scarcity.
• In 2017–2018, 157 countries reported average implementation of integrated water resources management of 48 per cent.
• Based on data from 62 out of 153 countries sharing transboundary waters, the average percentage of national transboundary basins covered by an operational arrangement was only 59 per cent in 2017.
