Study Notes
Land Utilisation
- Brundtland Commission Report (1987) introduced 'Sustainable Development' as a framework for global resource conservation.
- The report highlighted the importance of managing natural resources for future generations, published in the book "Our Common Future."
- Earth Summit in Rio de Janeiro (1992) further emphasized sustainable practices.
Purposes of Land Use
- Land is utilized for various purposes, categorized as follows:
- Forests: Crucial for biodiversity and ecosystem services.
- Non-cultivable Land: Includes barren land, land for buildings, roads, and industries.
- Other Uncultivated Land:
- Permanent pastures and grazing areas.
- Land with miscellaneous tree crops.
- Cultivable waste land (beyond five years uncultivated).
- Fallow Lands:
- Current fallow (uncultivated for one agricultural year or less).
- Other fallow (uncultivated for 1-5 agricultural years).
Land Degradation and Conservation Measures
- Continuous land usage without proper management leads to degradation, impacting society and the environment.
- Solutions include:
- Afforestation and management of grazing lands.
- Planting shelter belts and preventing overgrazing.
- Stabilization of sand dunes with thorny bushes.
- Proper management of waste lands and careful management of industrial activities.
Soil as a Resource
- Soil is a critical renewable resource that supports plant growth and various organisms.
- Considered a living system essential for life on Earth, highlighting the need for its preservation.
Land Use Patterns in India
- Determined by physical factors (topography, climate, soil types) and human factors (population density, technology, culture).
- India's total geographical area is approximately 3.28 million square kilometers.
- The net sown area represents land utilized for growing crops, while gross cropped area includes multiple sowings within an agricultural year.
