Global Soil Moisture Droughts to Intensify by 2050
Global Soil Moisture Droughts to Intensify by 2050
SouthAmerica · Published Sep 24, 2026
• A recent study published in Nature highlights the intensification of soil moisture droughts globally due to climate change.
• Using the Soil Moisture Severity Index (SSMI), researchers project that agricultural regions in South America, southern Europe, South Asia, and parts of North America will experience prolonged and severe droughts by mid-century.

Impact & Risks

The projected increase in drought severity and duration poses significant risks to global agriculture, particularly in regions like South America, southern Europe, and South Asia. Prolonged soil moisture deficits could lead to reduced crop yields, food insecurity, and economic losses. The study also highlights the vulnerability of agricultural systems to interannual climate variability, especially in Australia. Uncertainties in climate models and land-use changes further complicate drought risk assessments, underscoring the need for robust adaptation measures.
