Introduction
Land is one of the most fundamental natural resources, providing the basis for all human activities. It serves as the ground for agriculture, habitation, and infrastructure, and supports various ecosystems. In India, land resources play a critical role in supporting economic activities such as agriculture, industry, and forestry, as well as non-economic activities like wildlife preservation and human settlement. This article will delve into the different aspects of land resources, their distribution, utilization, and the challenges associated with optimizing their use.
What is Land?
- Land refers to the solid surface of the earth that is not permanently covered by water.
- It is marked by boundaries and includes ground and soil.
- As defined by Aldo Leopold, “Land is not merely soil; it is a fountain of energy flowing through a circuit of soils, plants, and animals.”
Characteristics of Land
- Land area/landmass refers to the total surface area of a geographical region or country.
- It is vital because humans live and perform all economic activities on land.
- Land also supports wildlife, natural vegetation, transport, and communication activities.
Significance of Land
- Supports 95% of our basic needs and requirements.
- Provides anchorage for roots, water, and nutrients for plant growth.
- Acts as a home for microorganisms, earthworms, and termites.
- Plays a key role in agriculture, employment generation, and industries like pottery.
Land Resources in India
Distribution of Land Resources
- India’s land distribution includes:
- 43% of plains: Suitable for agricultural activities and industrial development.
- 30% of mountains: Provides spots for tourism and a perennial flow of rivers.
- 27% of plateaus: Rich in minerals, fuels, and forests.
Land Use in India
- The land is used for economic activities (agriculture, industries, infrastructure, minerals) and non-economic activities (forests, rivers, lakes, wildlife, and human settlements).
Land Use Categories
The land in India is classified into several categories, and records are maintained by the Land Revenue Department. Some key categories include:
- Forest Land:
- The area classified as forest differs from the actual forest cover.
- Forests are vital for biodiversity, soil conservation, and maintaining ecological balance.
- Land Put to Non-Agricultural Uses:
- Includes land under settlements (rural and urban), infrastructure (roads and canals), and industries.
- Expands with the growth of the secondary and tertiary sectors.
- Barren and Wastelands:
- Land that may be classified as wasteland, such as barren hilly terrains, desert lands, and ravines.
- India has approximately 130 million square kilometers of wasteland.
- 56% water eroded areas
- 28% forest-degraded areas
- 6% saline and alkaline soils
- 10% wind-eroded areas
- Area under Permanent Pastures and Grazing Lands:
- Primarily owned by the village ‘Panchayat’ or the Government, with a small proportion being privately owned.
- Area under Miscellaneous Tree Crops and Groves:
- Land under orchards and fruit trees, mainly privately owned but not included in the net sown area.
- Culturable Waste-Land:
- Land left fallow for more than five years but can be cultivated after reclamation practices.
- Often used for jhum cultivation (shifting agriculture).
- Current Fallow:
- Land left without cultivation for one or less than one agricultural year.
- Fallowing helps land recoup its lost fertility through natural processes.
- Fallow other than Current Fallow:
- Cultivable land left uncultivated for more than one but less than five years.
- If left uncultivated for more than five years, it is categorized as culturable wasteland.
- Net Area Sown:
- The physical extent of land on which crops are sown and harvested at least once a year.
Changing Land Use Patterns in India
- Land-use patterns have changed significantly over time due to economic activities.
- The nature of land use varies from state to state:
- For example, 80% net sown area in Punjab and Haryana compared to less than 10% in Arunachal Pradesh, Mizoram, Manipur, and the Andaman and Nicobar Islands.
- Factors affecting land use include:
- Size of the economy
- Composition of the economy
- Pressure on land for agricultural activities
Optimizing the Use of Land Resources
To optimize land resources, several measures can be taken:
- Legalize and ease land leasing to enhance access and efficiency.
- Consolidate fragmented plots to improve productivity and equity for farmers.
- Create digitized and integrated land records for better management.
- Increase efficiency in forest land management.
- Convert waste and fallow land into productive uses through reclamation.
- Strengthen property rights, especially community rights over forest lands.
Constraints
Despite efforts, there are several challenges:
- Restrictive agricultural tenancy laws
- Conditions on leasing and high informal tenancy rates
- Small-sized land parcels
- Low productivity of forest lands
- Absence of conclusive titling records
Conclusion
Land is a limited yet vital resource that supports various aspects of life and economic activities. In India, the distribution and utilization of land resources vary widely due to geographical and climatic differences. Proper management and optimization of land use are essential for sustainable development, agriculture, and environmental conservation. Addressing challenges such as land degradation, informal tenancy, and land fragmentation is crucial to ensure the effective use of this valuable resource.
