The Global Water Crisis

As reported by UNESCO, 2 billion people around the world do not have access to safe drinking water. This accounts for 26% of the world’s population. Simultaneously, almost 10% of the population worldwide resides in countries subject to high or critical water stress. You can also take a look at the world’s most water-stressed countries in 2040. The global water supply is also being increasingly dedicated to agriculture and industrial growth. The severity of the global water crisis is evident from the fact that the urban population witnessing water scarcity has been forecasted to double from 930 million in 2016 to 1.7 billion-2.4 billion people in 2050. Regions including Central Africa, East Asia, and parts of South America with water abundance are expected to witness seasonal water scarcity in the future. On the other extreme, the water-scarce Middle East and the Sahel region in Africa will be subject to even worse water shortage.

The Victims of Unsafe Drinking Water

According to a report by UNICEF, several countries recorded less than half of their populations using improved water sources accessible on premises in 2022. Sub-Saharan Africa hosted the majority of the countries with limited access to clean water. Nine out of ten people were deprived of accessing an improved water source in the Central African Republic, Chad, Haiti, and South Sudan. At the same time, more than half of the 703 million people without basic drinking water resided in sub-Saharan Africa while a fifth belonged to Central and Southern Asia. 115 million people around the world still utilize surface water. Out of these, two-thirds of them lived in sub-Saharan Africa.

Water access in countries is influenced by income status. This is because only two-thirds of improved water sources are accessible in lower-middle-income countries. The situation in low-income nations is adverse since less than a third of these sources can be accessed on-premises. The gap between coverage of improved sources and improved sources that could be accessed on premises is higher in Burundi, Liberia, Malawi, Rwanda, South Sudan, and Uganda.

Our Methodology:

In order to compile a list of the 25 countries with the least access to safe drinking water, we sourced the proportion of the population who used safely managed water from a local source including piped water, boreholes or tube wells, protected dug wells, and protected springs. It is important to note that UNICEF declares drinking water safely managed when it is from a local source in the country which is accessible, available when required, and free from any contamination. Hence, this proportion represents the percentage of the total country’s population that had access to safe drinking water.

The metric was sourced from UNICEF and the most recent data is from 2022. The countries with least access to safe drinking water are ranked in descending order of our metric.
