Present Scenario of Global Salt Affected Soils, its Management and Importance of Salinity Research
Abstract: Salt-affected soils have gained global concern. The world population is increasing rapidly, while the cultivable land is decreasing gradually 1-2% per year. As a result it is threatening the sustained productivity from the limited land resources to meet food and nutritional demands. Soil degradation due to salinization is considered a major constraint for agricultural productivity. Currently approximately 1125 million hectares of lands are salt-affected, of which approximately 76 million hectares are affected by human-induced salinization and sodification. Therefore, tackling salinity problem is very crucial to achieve food security. Two strategies- fighting salinity and living with salinity are suggested by International Center for Agricultural Research in the Dry Areas (ICARDA) to overcome salinity problems. Conducting researches to find high salt tolerant plant species and remove salts from the affected lands applying bio-techniques are also very important. Minimizing the exposure of cultivable land to salinity and recovering or utilizing salt-affected land for agriculture is crucial to attain future food security.
