Land Resources and Agriculture Study Notes

Unit III Chapter 3 LAND RESOURCES AND AGRICULTURE

Observations on Land Use

Land is utilized in various forms, including as residence, for production, and recreation. It accommodates buildings, roads, schools, and agricultural fields, illustrating diverse uses such as urbanization and agricultural activities.

Land Use Categories

Land use within India is systematically recorded by the Land Revenue Department. Understanding how land is categorized aids in recognizing its utilization. The Survey of India oversees the measurement of geographical areas.

Categories of Land Use

Comprising various uses, land categories give insight into their extent and purpose:

  1. Forests: There's a clear distinction between actual forest cover and areas designated for forest growth. The latter is recognized in land revenue records, leading to possible increases in categorized forest area without a corresponding rise in actual forest coverage.

  2. Barren and Wastelands: Includes lands that are unsuitable for current cultivation techniques, such as deserts and barren hills.

  3. Land for Non-agricultural Uses: This category encompasses areas designated for urban settlements, infrastructure (like roads), and various industries.

  4. Permanent Pastures and Grazing Lands: Primarily owned by local councils or government entities, these lands support livestock grazing. Only a small percentage is privately owned.

  5. Miscellaneous Tree Crops and Groves: Includes land used for orchards and fruit-bearing trees, generally privately held.

  6. Culturable Wasteland: Areas left fallow for over five years that can potentially be reclaimed for agriculture.

  7. Current Fallow: Refers to land left uncultivated for one year or less, allowing the land to recuperate fertility naturally.

  8. Fallow other than Current Fallow: Cultivable land uncultivated for a period between one to five years—beyond five years, it is classified as culturable wasteland.

  9. Net Area Sown: Indicates total land area where crops are grown and harvested.

Land-use Changes in India

Changes in land use reflect evolving economic activities within a region, which often remain static in area but change functionally. Influences on land use can be broken down into three primary factors:

  1. Growth of the Economy: Economic expansion leads to increased pressure on land; with growing populations and income levels, marginal lands become cultivated over time.

  2. Change in Economic Composition: A growth in secondary and tertiary sectors typically results in a shift from agricultural to non-agricultural land use. This is particularly prominent in developing regions like India.

  3. Pressures on Agricultural Land: Despite a decline in agricultural sector GDP contribution, the demand for agricultural land does not diminish due to the growing population reliant on farming for sustenance.

Comparative Analysis of Land Use (1950-51 vs. 2019-20)

A significant shift in land-use categories emerged over nearly seven decades, where increases were noted in:

  • Area under forests (largely related to demarcation)

  • Non-agricultural uses

  • Current fallow land

  • Net area sown

Observations on Increases

  1. The increase in non-agricultural land is chiefly due to urbanization and infrastructural development, leading to a loss of agricultural lands.

  2. Increase in forest area categorization without actual cover growth highlights a regulatory approach rather than ecological improvement.

  3. Current fallow rates fluctuate significantly due to varying agricultural cycles and rains.

  4. The rise in net area sown area marks reclamation of lands classified previously as wasteland for cultivation productivity, indicating a shift in agricultural practices.

Declines Noted

Certain categories such as barren lands, culturable wastelands, and tree crops have recorded significant declines, attributed to growing competition for space from agricultural and non-agricultural activities.

Common Property Resources

Land ownership divides into private lands and Common Property Resources (CPRs). CPRs serve communities’ needs, including fodder, firewood, and other minor forest products, particularly critical for livelihoods of agricultural laborers and women in rural areas.

Agricultural Land Use in India

Agricultural lands contribute significantly to livelihoods, contrasting sharply with secondary and tertiary activities:

  1. Land plays a critical role in agricultural productivity, directly correlated with poverty incidence among those without land access.

  2. Land quality impacts agricultural yield significantly, unlike other economic sectors.

  3. Socially, land ownership offers security and status in rural structures, affecting credit access and stability. Aggregate cultivable land's availability indicates there has been a decline in proportion to total reporting areas over time. This pinpointing extends beyond net sown areas to include fallow and wasteland conditions.

Challenge in Expanding Net Sown Areas

Given the limited land availability, the necessary evolution toward improving yield from existing areas becomes paramount, calling for land-saving technologies.

Technologies for Improvement

  1. Yield Increase Technologies: Enhancing per unit crop output per acre.

  2. Land-Use Intensity Technological Improvements: Focusing on maximizing the output from total land used throughout the year.

Cropping Intensity

The Cropping Intensity (CI) measures land utilization efficiency, computed with:
ext{CI} = rac{ ext{Gross Cropped Area}}{ ext{Net Sown Area}} imes 100

Cropping Seasons

  • Kharif Season: Coincides with the southwest monsoon; crops include rice and cotton.

  • Rabi Season: Follows the winter months; commonly grows wheat and gram.

  • Zaid Season: Occurs between Rabi and Kharif, suitable for crops such as fruits and fodder. Varieties may shift between southern India, where climatic factors allow for multiple plantings annually, versus northern regions with more rigid cycles.

Types of Farming

Farming classifications depend on moisture sources, falling broadly into:

  • Irrigated Farming: Sourced either for protection against moisture deficiency or to achieve high productivity levels. - Rainfed Farming: Further divided into dryland (under 75 cm rainfall) and wetland farming, which faces potential flood hazards and high-water demanding crops such as rice.

Foodgrains in Indian Agriculture

Foodgrains dominate India's agricultural landscape, consuming around two-thirds of cropped areas, divided into:

  1. Cereals: Comprising 54% of cropped area, India ranks third globally in cereal production. Major grains include rice and wheat, with notable regional variations in yield intensity and cultivation practices.

  • Rice: A staple for a significant Indian population, demonstrating diverse cultivation patterns across varying climatic zones. Major producing states include West Bengal and Punjab.

  • Wheat: Following rice, produced chiefly in northern and central India, with significant yield differences across regions. Areas like Punjab and Haryana are known for high output per hectare.

  1. Pulses: Mainly cultivated in drylands, pulses play a crucial role in vegetarian diets, yet yield varies widely among regions.

  2. Oilseeds: Cultivated primarily in dryland areas, oilseed production is crucial to the economy, particularly soya and groundnut across various states.

  3. Fibre Crops: Cotton, predominantly in kharif season and jute in eastern states are key commodities for textile industries.

  4. Other Major Crops: Sugarcane thrives under diverse climatic conditions, while tea and coffee serve significant domestic and international markets.

Agricultural Development in India

Post-independence, India propelled an agricultural transformation with numerous programs aimed at enhancing food security, mainly echoed through the Green Revolution, leveraging high-yielding index technology across irrigated landscapes. The result proved notably successful yet regionally uneven in growth metrics, necessitating strategic outreach to rainfed blocks and integrated agro-climatic plans.

Current Issues in Indian Agriculture

Common agricultural challenges include reliance on monsoon patterns, insufficient irrigation facilities, financial constraints that trap farmers into cycles of indebtedness, and systematic flaws in land reform efforts. Additionally, the limitations imposed by fragmentation of holdings hinder larger productivity gains.

Conclusion

The continual examination of land resource utilization illustrates the complex interplay between economic growth and agricultural development, focusing on sustainable practices that can withstand the pressures of modernization, climate change, and resource limitations.
