In 2015, the United Nations engineered the Sustainable Development Goals (replacing the Millennium Development Goals). They focus on health, education, poverty, hunger, climate change, water sanitation, and hygiene. A major focus was clean water and salinization. Experts working in these fields have designed the WASH concept. WASH focuses on safe drinkable water, hygiene, and proper sanitation. The group has had a major impact on the sub-Saharan region of Africa, particularly Ivory Coast. By 2030, they plan to have universal and equal access to safe and affordable drinking water.
