Land Use Concepts and Global Distribution
Notes
Land use planning is critical for sustainable development, especially in densely populated countries like the Philippines.
Examples
- Rice terraces in Northern Luzon (arable land)
- Coconut plantations in Southern Philippines (permanent crops)
- Cattle ranches in Mindanao (pastureland)
Understanding land use patterns helps in planning sustainable development. The Food and Agriculture Organization (FAO) classification system provides a framework for analyzing how land resources are utilized globally and nationally.
Main points
