They are renewable but limited, and increasing human pressure has led to overuse and degradation. Land Resources: a. Types of Land Use: Agricultural land – used for farming and animal grazing. Forest land – provides biodiversity, climate regulation, and raw materials. Pastures – used for grazing livestock. Non-agricultural land – includes land for settlements, industries, roads, etc. Fallow land – temporarily unused for agriculture to restore fertility. b. Land Degradation: Causes: deforestation, overgrazing, mining, urban sprawl, and poor farming practices. Effects: soil erosion, loss of fertility, desertification. c. Conservation of Land: Methods include afforestation, contour plowing, terrace farming, crop rotation, and land use planning Water Resources: a. Types of Water Sources: Surface water – rivers, lakes, ponds. Groundwater – water stored underground in aquifers. Rainwater – essential for agriculture and replenishing water bodies. Marine w
