What Is Agriculture as Natural Resource Management?
Natural resource management (NRM) involves practices that sustainably utilize and conserve resources like land, water, and biodiversity for current and future generations. Agriculture, a cornerstone of NRM, entails cultivating crops and raising livestock to meet human needs. Originating around 8,500 BCE in the Fertile Crescent, agriculture allowed humans to settle, replacing nomadic lifestyles. Today, it includes:
- Crop Cultivation: Planting grains, vegetables, or trees (silviculture).
- Livestock Rearing: Raising cattle, sheep, pigs, or poultry.
- Systems: Monoculture (single species) or polyculture (multiple species).
In India, agriculture transforms landscapes, replacing natural ecosystems with agroecosystems of wild and domesticated species, impacting both food security and biodiversity.
Types of Agricultural Practices in India
India’s diverse geography and cultures foster a range of sustainable agriculture practices, broadly categorized into settled and shifting cultivation.
Settled Cultivation
Settled cultivation dominates modern farming, involving permanent land use with plowing, crop rotation, and irrigation to maintain soil fertility management. Originating 6,000 years ago in Mesopotamia, plows reduced manual labor. In India, regions like Punjab and Uttar Pradesh practice large-scale settled farming, leveraging floodplains for nutrient-rich soil. Key practices include:
- Crop Rotation: Alternating crops to preserve soil health.
- Irrigation: Diverting water from rivers or groundwater to boost yields.
- Nutrient Addition: Using fertilizers to enhance productivity.
Innovative methods address challenging terrains, ensuring sustainability.
Terrace Farming
In hilly regions like Himachal Pradesh and Northeast India, terrace farming creates flat plots on slopes using earth and rock walls. Benefits include:
- Soil Retention: Prevents erosion on steep slopes.
- Water Management: Channels water through gates for controlled irrigation.
- Crop Diversity: Supports rice, wheat, barley, and vegetables.
Terrace farms often use mixed farming to maximize productivity.
Rice-Fish Farming
Rice-fish farming integrates fish into rice fields, a traditional practice in India, China, and Southeast Asia. Fish enter fields naturally or are introduced, offering:
- Weed Control: Fish eat weeds, reducing pesticide use.
- Natural Fertilization: Fish excreta enriches soil.
- Organic Production: Minimizes chemical inputs for safer crops.
Fish are harvested using nets or by draining fields into trap ponds, enhancing food security.
Agroforestry
Agroforestry in India combines trees with crops or livestock, as seen in Nagaland’s home gardens or Sikkim’s cardamom cultivation. Benefits include:
- Diverse Yields: Trees provide fruit, timber, or fodder.
- Biodiversity: Maintains soil ecology and wildlife habitats.
- Sustainability: Shade-tolerant crops like coffee thrive under forest canopies.
These practices showcase how settled cultivation adapts to India’s diverse landscapes.
Shifting Cultivation
Shifting cultivation, known as jhum in Northeast India, is practiced in forested, hilly areas with poor soil. Plots are cleared, cultivated for 2–3 years, then left fallow for soil recovery. Known as slash-and-burn, it involves:
- Clearing: Cutting and burning vegetation to fertilize soil with ash.
- Polyculture: Planting diverse crops like rice and millet for reliable yields.
- Fallow Periods: Allowing vegetation regrowth to restore nutrients.
The jhum cultivation system, or swidden, rotates multiple plots, with most land fallow at any time. In Arunachal Pradesh and Nagaland, jhumias expertly manage fields based on local biodiversity and soil knowledge.
Alder-Based Farming
In Nagaland, alder-based farming integrates nitrogen-fixing Alder trees (Alnus nepalensis) into jhum fields. Benefits include:
- Soil Stabilization: Roots prevent erosion on slopes.
- Nutrient Enrichment: Nitrogen fixation enhances soil fertility.
- Crop Diversity: Supports paddy, turmeric, and other crops.
This agroforestry approach improves jhum productivity and sustainability.

Impact of Agriculture on Environment and Society
Agriculture has profoundly shaped India’s environment and society, with both positive and negative effects.
Environmental Impacts
- Landscape Transformation: Replaces natural ecosystems with agroecosystems, reducing wild biodiversity.
- Soil Degradation: Shortened fallow periods in shifting cultivation deplete nutrients.
- Resource Competition: Increases conflicts over land and water as farming expands.
Sustainable practices like agroforestry mitigate these impacts by preserving biodiversity and soil health.
Societal Impacts
- Food Security: Enabled settled communities and cultural development.
- Economic Shifts: Made farming central to livelihoods, though recent unviability challenges farmers.
- Diet Narrowing: Relies heavily on wheat, rice, and corn, reducing dietary diversity.
Balancing productivity with sustainability is key to addressing these impacts.
The Green Revolution: A Double-Edged Sword
The Green Revolution in the 1960s transformed Indian agriculture through high-yield crop varieties, chemical fertilizers, and mechanization. Initiated by Norman Borlaug’s wheat varieties, it boosted food production, making India a wheat exporter. However, it introduced challenges:
- Heavy Chemical Use: Fertilizers and pesticides polluted land and water.
- Water Demand: Large-scale irrigation depleted groundwater and required reservoirs.
- Mechanization: Displaced manual labor, altering rural economies.
- Environmental Harm: Degraded soil and disrupted traditional NRM practices.
Today, the Green Revolution faces criticism for its unsustainable practices, prompting a shift toward organic and sustainable agriculture practices.
Challenges in Modern Agriculture
India’s agriculture faces significant hurdles, threatening its role as a viable NRM practice:
- Population Pressure: Rising food demand strains resources.
- Land Degradation: Overexploitation from intensive farming reduces soil fertility.
- Competing Land Uses: Urbanization, mining, and industrialization limit farmland.
- Economic Viability: Low returns make farming unattractive for many.
Adopting sustainable NRM practices is critical to overcoming these challenges and ensuring agriculture remains productive and environmentally friendly.
Innovations for Sustainable Agriculture
To address modern challenges, Indian farmers are innovating within agriculture as natural resource management:
- Improved Fallow Management: Planting diverse trees and high-value crops like pineapple in jhum fallows to enhance soil recovery.
- Organic Farming: Reducing chemical inputs, as seen in rice-fish systems, to promote healthier ecosystems.
- Agroforestry Expansion: Scaling practices like alder-based farming to improve soil fertility and biodiversity.
- Policy Support: Government initiatives promote sustainable practices through subsidies and training.
These innovations align with global sustainability goals, ensuring agriculture supports both people and the planet.
Conclusion
Agriculture as natural resource management in India blends tradition and innovation to sustainably feed a growing population. From jhum cultivation in Northeast India to terrace farming in the Himalayas, diverse practices showcase resilience and adaptability. While the Green Revolution boosted yields, its environmental costs highlight the need for sustainable agriculture practices like agroforestry and rice-fish farming. By addressing challenges like land degradation and economic unviability, India can ensure agriculture remains a cornerstone of food security and environmental health.
