Land cover refers to the physical material present on the Earth's surface, such as forests, grasslands, water bodies, and urban areas. It helps us understand how land is used and managed, which is crucial for planning and environmental conservation. Different types of land cover can influence local climates, biodiversity, and even human activities. Monitoring land cover changes is essential for assessing the impact of human activities, like deforestation or urbanization. Tools like satellite imagery and geographic information systems (GIS) are often used to track these changes over time. Understanding land cover can aid in protecting ecosystems and promoting sustainable development.
