The 2030 Agenda for Sustainable Development was adopted by all United Nations member states in 2015. It is a plan of action for both developing and developed nations to achieve 17 sustainable development goals, which cover a range of environmental and social issues, by 2030.

Today is World Water Day, so let’s take a closer look at the sixth goal, which aims to ensure access to safe drinking water and sanitation for all.

Currently, there are more than 733 million people living in places with high or critical levels of water stress. Climate change, pollution and development have created tremendous threats to water security in many countries, with developing nations the most vulnerable.

The Sustainable Development Goals Report 2022 revealed that at current rates, 1.6 billion people will lack safely managed drinking water by 2030, and 2.8 billion people will lack safely managed sanitation. Meeting the targets by 2030 will require a fourfold increase in the pace of progress.
