The world’s most arid regions
The world map shows the 20 countries and regions that were worst hit by water scarcity in 2020. On a scale of 1 to 5, their so-called water stress score is 5 or a little less – so water shortage is a particularly pressing problem there. Click on the cross icons to find out more.

Palestinian territories
Water stress score: 5
Population: 5.1 million (source: Our World in Data)
One of the ‘top 7’ most water-scarce regions. This is linked to the aridity of the region, but also to the conflict between Israel and the Palestinian territories. The population has a water supply of 50 litres per person and day, which is only around half of the minimum amount recommended by the World Health Organization (WHO).

Lebanon
Water stress score: 4.98
Population: 5.6 million (source: World Bank)
Lebanon is facing a political crisis, a large number of refugees and, partly because of that, serious water problems. According to the UN, the country’s water supply system is often on the brink of collapse. More than 70% of households do not have secure access to water.

Jordan
Water stress score: 4.89
Population: 11.2 million (source: World Bank)
The water supply is one of the biggest risk factors in Jordan’s development. At present, only around two thirds of the population’s requirements can be met. This primarily affects poor households. Model calculations suggest that the situation will be exacerbated by climate change.

Libya
Water stress score: 4.82
Population: 6.7 million (source: World Bank)
A lack of rainfall and overuse of existing resources are creating considerable challenges for Libya in securing its water supply. Most of the available water is taken by the agricultural sector, which accounts for 80% of use. In the long term, Libya will probably be dependent on desalination plants.
Yemen
Water stress score: 4.79
Population: 33 million (source: World Bank)
Yemen has long been affected by water scarcity, and civil war is exacerbating the problem. The demand for water currently far exceeds the supply, with 90% being used in agriculture. Climate change and population growth are making the situation even more difficult, and conflicts over resources cannot be ruled out in the future.
