    Study Notes

    Land Resources

    • Proper utilization of marginal or waste lands through alternate land use systems to maximize productivity and scope for beneficial developmental activities.
    • Development of rural areas with clear plans for improving the economy of the region.

    Soil

    • Soil is a dynamic natural body capable of supporting a vegetative cover, composed of weathered rocks, water, oxygen, and organic materials.
    • Soil formation processes: physical weathering, chemical weathering, and biological weathering.
    • Factors influencing soil formation: parent material, living organisms, climate, topography, and time.
    • Soil types: Igneous, Sedimentary, and Metamorphic rocks.
    • Soil profile functions: facilitating nutrient cycle, food and biomass production, storing water, regulating water supply, filtering groundwater, and serving as a biological habitat.

    Water Conservation

    • Decreasing runoff losses, reducing evaporation losses, storing water in soil, reducing irrigation losses, reusing water, and preventing wastage of water.
    • Rainwater harvesting: modern rainwater harvesting, objectives, and techniques.
    • Techniques of rainwater harvesting: constructing special structures like dug wells, percolation pits, lagoons, check dams, tanks, etc.

    Watershed Management

    • A watershed is an area of land that drains to a common location, varying in size from small streams to entire areas draining to an ocean.
    • Advantages of watershed management: ensuring ecological balance, stabilizing income, minimizing risks of drought, landslides, floods, and reducing erosion and sediment production.

    Water Cycle

    • Source of water: surface water (rainfall, snow) and ground water (confined and unconfined aquifer).
    • Overexploitation of ground water: ground subsidence, lowering water table, reduced surface water flow, increased power consumption, water logging, and ground water pollution.

    Water Calamities

    • Flood: types (flash, river, coastal), causes (upslope and downslope factors), and effects (loss of life and property, damage to crops, etc.).
    • Drought: types (meteorological, hydrological, agricultural), causes (dry season, climate change, erosion, and human activity), and effects (decrease in crop growth, dust storm, famine, etc.).

    Dams

    • Advantages of dams: electricity generation, employment, irrigation water supply, drinking water supply, reduction in famine, and flood control.
    • Disadvantages of dams: displacement of people, loss of forest, changes in aquatic environment, waterlogging, microclimatic changes, reduced water flow, flash flood, and salt water intrusion.
