Real-World Examples of Land Cover Change: Case Studies

📚 Quick Study Guide

• 🌍 Land Cover vs. Land Use: Land cover refers to the physical material at the surface of the earth (e.g., vegetation, water, bare earth). Land use refers to how people are using the land (e.g., agriculture, residential, industrial).
• 🌳 Deforestation: The clearing of forests for other land uses, such as agriculture, urbanization, or logging.
• 🌾 Agricultural Expansion: The conversion of natural land cover (e.g., forests, grasslands) into agricultural land.
• 🏙️ Urbanization: The growth of urban areas, leading to the conversion of rural land into urban land.
• 🏜️ Desertification: The process by which fertile land becomes desert, typically as a result of drought, deforestation, or inappropriate agriculture.
• 🌊 Coastal Change: Alterations to coastal land cover due to erosion, sea-level rise, and human activities.
• 🔥 Wildfires: Can rapidly change land cover, destroying vegetation and altering ecosystems.
