| A | Desertification | A type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly arid. |
| B | Soil erosion | A form of soil degradation, it is the denudation of the fertile top layer of the soil. |
| C | Water-logging | It is the saturation of soil with water where the soil is nearly saturated with water much of the time such that its air phase is restricted and anaerobic conditions prevail. |
| D | Soil Salinity | It is the salt content in the soil; the process of increasing the salt content is known as salinization. |
