Study Notes

Transformation of Resources

Resources are elements from the environment that meet human needs, requiring technological accessibility, economic feasibility, and cultural acceptance.
Transformation of materials in the environment into resources is a result of human activity.

Classification of Resources

Origin: Biotic (living) and Abiotic (non-living) resources.
Exhaustibility: Renewable resources (naturally replenished) and Non-renewable resources (limited supply).
Ownership: Individual, community, national, and international resources.
Status of Development: Potential resources, developed stock, and reserves.

Resource Planning in India

A complex process that includes identifying and inventorying resources regionally, focusing on vegetation, wildlife, human activities, and infrastructure.
Land is a finite asset, necessitating careful usage and planning.

Land Use Patterns in India

Total geographical area of India: 3.28 million sq km; land use data available for 93% of this area.
The net sown area indicates the extent of land cultivated; gross cropped area includes multiple sowings in a year.
Influences on land use include physical features such as topography, climate, and human factors like population density and technology.

Soil as a Resource

Vital renewable resource, essential for plant growth and supporting living organisms.
Formation of soil takes millions of years, influenced by relief, parent rock, climate, and biological factors.
Degradation of soil occurs due to activities like deforestation, overgrazing, and mining, exacerbating natural erosion processes.

Major Soil Types in India

Alluvial Soil: Found in river basins; consists of varying proportions of sand, silt, and clay; classified into old (Bangar) and new (Khadar) alluvial soils.
Black Soil: Characterized by fine clayey composition; excellent moisture retention; rich in calcium and magnesium but low in phosphoric content.

Challenges and Opportunities

Resource-rich regions may remain economically backward due to historical factors like colonization and lack of technological advancement.
Conversely, resource-poor areas can be economically developed by leveraging technology and infrastructure.
Responsible resource planning, technological development, and institutional changes are crucial for sustainable development.

Environmental Concerns

Land degradation is intensified through industrial waste disposal, overgrazing, and excessive irrigation leading to salinity and alkalinity in soil.
Conservation measures are essential for restoring and maintaining soil health and environmental stability.
