Introduction
Agricultural regionalisation refers to the systematic division of land into regions based on the predominant agricultural practices, crops grown, soil types, climatic conditions, and socio-economic factors. In a diverse country like India, with its vast geographical expanse and varied agro-climatic zones, agricultural regionalisation serves as a critical tool for understanding spatial patterns, resource allocation, and policy formulation.
This process is essential for optimizing agricultural production, ensuring food security, and addressing regional disparities. By identifying specific characteristics of agricultural regions, planners can focus on crop suitability, resource management, and sustainable farming practices.
Importance of Agricultural Regionalisation in India
India is an agrarian country with nearly 54% of its workforce engaged in agriculture and allied activities. The agricultural landscape is diverse, shaped by:
- Climatic Variability: From tropical monsoons in Kerala to arid conditions in Rajasthan.
- Soil Diversity: Including alluvial soils in the Indo-Gangetic plain, black soils in the Deccan, and laterite soils in the Western Ghats.
- Cultural Practices: Traditional knowledge and farming methods unique to each region.
- Economic Factors: Access to markets, credit facilities, and infrastructure.
Agricultural regionalisation provides a structured approach to addressing these variations, ensuring better resource utilization, and enhancing productivity.
Methods of Agricultural Regionalisation
- Crop Combination Method:
- Introduced by J.C. Weaver, this method identifies regions based on the combination of crops cultivated.
- Areas with the highest concentration of a single crop are classified as monoculture zones.
- Example: Punjab and Haryana for wheat, Kerala for spices.
- Agro-Climatic Zoning:
- Classifies regions based on climate, soil type, and cropping patterns.
- The Planning Commission of India identified 15 agro-climatic zones.
- Land Capability Classification:
- Evaluates the land’s potential for agricultural use.
- Considers factors like soil fertility, topography, and water availability.
- Economic Regionalisation:
- Based on socio-economic factors such as irrigation facilities, market accessibility, and input availability.
- Geographical Regionalisation:
- Utilizes natural features like rivers, mountains, and plateaus to define regions.

| Arid Regions | Rajasthan, Gujarat | Bajra, Oilseeds | Sandy Soils | Hot Desert |
Agro-Climatic Zones of India
India’s agro-climatic zones were delineated to promote region-specific agricultural development. The 15 zones include:
- Western Himalayan Region
- Eastern Himalayan Region
- Lower Gangetic Plains
- Middle Gangetic Plains
- Upper Gangetic Plains
- Trans-Gangetic Plains
- Eastern Plateau and Hills
- Central Plateau and Hills
- Western Plateau and Hills
- Southern Plateau and Hills
- East Coast Plains and Hills
- West Coast Plains and Hills
- Gujarat Plains and Hills
- Western Dry Region
- Island Region
| Zone | Key States | Dominant Crops | Challenges |
|---|---|---|---|
| Western Himalayan Region | Himachal Pradesh | Apples, Rice | Soil erosion, cold climate |
| Lower Gangetic Plains | West Bengal | Rice, Jute | Flooding, soil salinity |
| Southern Plateau | Karnataka, Telangana | Millets, Pulses | Water scarcity |
Benefits of Agricultural Regionalisation
- Enhanced Productivity: Aligns crop selection with regional suitability.
- Efficient Resource Utilization: Optimizes use of water, fertilizers, and seeds.
- Targeted Policy Interventions: Facilitates region-specific strategies.
- Sustainability: Promotes environmentally friendly practices.
Challenges in Agricultural Regionalisation
- Data Limitations:
- Inadequate availability of accurate and up-to-date agricultural data.
- Climatic Uncertainty:
- Increasing frequency of extreme weather events.
- Infrastructure Gaps:
- Limited irrigation and storage facilities in some regions.
- Economic Disparities:
- Uneven distribution of subsidies and support.
- Cultural Resistance:
- Farmers’ reluctance to adapt to new crop patterns or methods.
| Challenge | Solution |
|---|---|
| Data Limitations | Improved remote sensing technology |
| Climatic Uncertainty | Promotion of climate-resilient crops |
| Infrastructure Gaps | Investments in irrigation and storage |
| Economic Disparities | Equitable subsidy distribution |
