Land Resources
- Land is a naturally occurring finite resource.
- It provides the base for survival of living beings.
- It holds everything that constitutes terrestrial ecosystems.
- Increased demand on land in modern times due to the rise in human population and resultant activities has resulted in degradation of land quality and quantity, decline in crop production, and competition for land.
LAND IS CRUCIAL FOR -
- Food security and sustainable agriculture.
- Biodiversity conservation and ecosystem health.
- Climate change mitigation and adaptation.
- Sustainable development and human well-being.
CHALLENGES -
- Growing population: Increasing demand for food, water, and resources puts pressure on land resources.
- Climate change: Rising temperatures, changing precipitation patterns, and extreme weather events can threaten land productivity and biodiversity.
- Urbanization: Expanding cities and infrastructure can lead to land degradation and habitat loss.
- Land and Land Resources refer to a delineable area of the earth’s terrestrial surface, having all attributes of the biosphere immediately above or below this surface,
- including those of the
- near-surface climate, the soil and terrain forms,
- the surface hydrology (including shallow lakes, rivers, marshes and swamps),
- the near-surface sedimentary layers and associated groundwater and geo-hydrological reserve,
- the plant and animal populations, the human settlement pattern
- physical results of past and present human activity (terracing, water storage or drainage structures, roads, buildings, etc.) Key Components:
- Soil: The lifeblood of land, providing nutrients and support for plants, influencing water availability and filtering pollutants.
- Climate: Temperature, precipitation, wind, and sunlight patterns affect land suitability for various uses and influence soil fertility and productivity.
- Topography: Landforms like mountains, valleys, and plains shape terrain and influence water flow, erosion, and human development.
- Vegetation: Forests, grasslands, and other plant communities provide habitat, regulate water cycles, and influence soil quality.
- Biodiversity: The variety of life forms inhabiting the land, essential for ecosystem health and functioning.
- Water resources: Surface and groundwater resources are crucial for drinking, irrigation, and industrial activities.
- Minerals and energy resources: Deposits of valuable minerals, fossil fuels, and renewable energy sources can be found within or under the land.
Types of Land Resources:
- Agricultural land: Used for crop production, animal grazing, and horticulture.
- Forest land: Provides timber, fuelwood, non-timber products, and ecosystem services.
- Pastoral land: Supports livestock grazing and nomadic herding.
- Fisheries and aquaculture: Harvests aquatic resources from oceans, rivers, and lakes.
- Urban and industrial land: Used for settlements, infrastructure, and industrial activities.
- Protected areas: Dedicated to conservation of biodiversity and natural ecosystems.
