Land classification is the process of categorizing land based on its characteristics and potential uses. This can include factors such as soil type, climate, vegetation, and topography. By classifying land, planners and researchers can better understand how to manage resources, support agriculture, and protect natural habitats. Different systems of land classification exist, such as the United Nations Food and Agriculture Organization (FAO) classification, which helps in assessing land for agricultural productivity. Another example is the U.S. Geological Survey (USGS) land cover classification, which focuses on the physical and biological cover of the land. These classifications aid in environmental planning and conservation efforts.
