Water scarcity affects over 40 percent of the human population. This alarming figure is projected to rise as temperatures continue to increase globally. While 2.1 billion people have experienced improvements in areas of water and sanitation since the 1990s, issues of water insecurity, drought and desertification are affecting every continent. By the year 2050, it is projected that one in every four people will suffer from recurring water shortages.
Achieving safe and affordable drinking water for all by 2030 requires global investment in infrastructure, the provision of safe sanitation facilities, developing effective waste treatment facilities and improving basic education on hygiene-practices. Furthermore, it is essential global efforts are centered on protecting and restoring water-related ecosystems.
In 2015, approximately 4.5 billion people lacked access to safely managed sanitation services, while a further 2.3 billion lacked any form of basic sanitation.
The task of ensuring universal access to safe and affordable drinking water will involve providing 800 million people with basic service and improving the accessibility of existing sanitation services to a further 2 billion people.
