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.
