- The International Soil and Water Forum 2024 was held in Bangkok.
- The report was titled ‘The Global Status of Salt-Affected Soils’ by FAO.
- Nearly 1.4 billion hectares of land, or 10.7 per cent of the global land area, is affected by salinity.
- Salt-affected soils are a specific group of soils that have elevated amounts of soluble salts (saline soils) that adversely affect the growth of most plants.
- Currently, ten countries — Afghanistan, Australia, Argentina, China, Kazakhstan, Russia, the United States, Iran, Sudan, and Uzbekistan — account for 70 per cent of the world’s salt-affected soils.
- The 3 largest areas with salt-affected soils were found in Australia (357 million hectares or mha), Argentina (153 mha) and Kazakhstan (94 mha).
- The 3 countries most affected by salinity and sodicity together were Oman (93.5 per cent of the country land area), Uzbekistan (92.9 per cent) and Jordan (90.6 per cent).
- India had a salt-affected area of approximately 6.72 million ha, or 2.1 per cent of its total geographic area.
- Of that, 2.95 million ha were saline and the remaining 3.77 million ha were sodic.
- Gujarat (2.23 mha), Uttar Pradesh (1.37 mha), Maharashtra (0.61 mha), West Bengal (0.44 mha) and Rajasthan (0.38 mha) made up about 75 per cent of the country’s salt-affected soils.
