Global map of salt-affected soils
The Food and Agriculture Organization (FAO) launched the Global Map of Salt-Affected Soils, a key tool for halting salinization and boosting productivity. The map estimates that there are more than 833 million hectares of salt-affected soils around the globe (8.7% of the planet). Most of them can be found in naturally arid or semi-arid environments in Africa, Asia and Latin America. However, the map also shows that 20 to 50 percent of irrigated soils in all continents are too salty, meaning over 1.5 billion people worldwide face significant challenges in growing food due to soil degradation.
