Land degradation is the process by which land quality is diminished due to human activities and natural processes. It can result in the loss of productivity and biodiversity, as well as the degradation of ecosystem services such as water and nutrient cycling. Land degradation can be caused by factors such as deforestation, soil erosion, overgrazing, urbanization, and mining. This research area aims to understand the causes and impacts of land degradation, as well as to develop strategies and practices for sustainable land management and rehabilitation. By studying land degradation, researchers can work towards preserving and restoring the health and productivity of the world's lands for future generations.
