Q12.

Discuss about the cropping patterns of Middle Gangetic Plain and Western Plateau and hills.

How to Approach

This question requires a comparative analysis of cropping patterns in two distinct agro-climatic zones of India. The approach should be to first define each region, then detail their unique geographical and climatic characteristics influencing cropping patterns. Subsequently, a comparative analysis highlighting similarities and differences in crops cultivated, farming practices, and challenges faced should be presented. Finally, a brief discussion on emerging trends and potential solutions can be included. A tabular comparison would be beneficial for clarity.

Introduction

India's diverse agro-climatic zones give rise to varied cropping patterns, reflecting the interplay of geography, climate, and socio-economic factors. The Middle Gangetic Plain (MGP) and the Western Plateau and Hills represent contrasting agricultural landscapes. The MGP, a fertile alluvial plain, is characterized by abundant water and rich soil, while the Western Plateau and Hills, comprising regions like the Deccan Plateau and Chota Nagpur Plateau, face limitations in water availability and undulating terrain. Understanding these variations is crucial for formulating effective agricultural policies and promoting sustainable practices. This response will discuss the cropping patterns of these two regions, highlighting their similarities and differences.

Middle Gangetic Plain (MGP) – Cropping Patterns

The Middle Gangetic Plain, spanning across Uttar Pradesh, Bihar, and parts of Jharkhand, is one of the most densely populated and fertile regions of India. It is a part of the Indo-Gangetic Plain, characterized by alluvial soils deposited by the Ganges and its tributaries. The climate is humid subtropical, with distinct monsoon and winter seasons.

Key Characteristics & Cropping Patterns

  • Soil: Alluvial, fertile, high in nutrients.
  • Climate: Humid subtropical, high rainfall.
  • Dominant Crops:
    • Rice: The dominant Kharif (monsoon) crop, especially in the eastern part.
    • Wheat: The primary Rabi (winter) crop.
    • Sugarcane: Important commercial crop, particularly in western UP.
    • Maize: Increasingly popular, especially as a rotational crop.
    • Pulses (Gram, Arhar): Grown as a source of protein and to improve soil fertility.
    • Oilseeds (Mustard, Soyabean): Grown in smaller areas.
  • Cropping Systems: Rice-wheat cropping system is the most prevalent, leading to soil exhaustion and groundwater depletion.
  • Challenges: Soil degradation, waterlogging, salinity, pest infestations, and climate change impacts.

Western Plateau and Hills – Cropping Patterns

The Western Plateau and Hills encompass a vast area including the Deccan Plateau, Chota Nagpur Plateau, and parts of the Western Ghats. The topography is uneven, with varying altitudes and soil types. The climate ranges from semi-arid to moist deciduous, with significant regional variations.

Key Characteristics & Cropping Patterns

  • Soil: Red and black soils (Deccan Plateau), laterite soils (Western Ghats), and forest soils (Chota Nagpur Plateau). Soil fertility varies significantly.
  • Climate: Semi-arid to moist deciduous. Rainfall is more erratic compared to the MGP.
  • Dominant Crops:
    • Jowar (Sorghum): Staple crop in many areas, drought-resistant.
    • Bajra (Pearl Millet): Another important Kharif crop, particularly in drier regions.
    • Groundnut: Important oilseed crop, especially in the Deccan Plateau.
    • Cotton: Major commercial crop, grown extensively in the rain-fed areas.
    • Millets (Ragi, Small Millet): Grown in hilly areas and marginal lands.
    • Tea and Rubber: Cultivated in the Western Ghats, benefiting from the high rainfall and undulating terrain.
  • Cropping Systems: Rain-fed agriculture dominates. Mixed cropping is common to mitigate risks.
  • Challenges: Water scarcity, soil erosion, undulating terrain, poor infrastructure, and low productivity.

Comparative Analysis: MGP vs. Western Plateau and Hills

Feature Middle Gangetic Plain (MGP) Western Plateau and Hills
Soil Alluvial, fertile Red, black, laterite, forest – varied fertility
Climate Humid subtropical, reliable rainfall Semi-arid to moist deciduous, erratic rainfall
Dominant Crops Rice, Wheat, Sugarcane Jowar, Bajra, Groundnut, Cotton
Irrigation Well-irrigated, but groundwater depletion Predominantly rain-fed
Cropping System Rice-wheat dominant, unsustainable Mixed cropping, more sustainable but lower yields
Challenges Soil degradation, waterlogging, salinity Water scarcity, soil erosion, undulating terrain

Emerging Trends and Potential Solutions

Both regions face challenges related to climate change and unsustainable practices. The MGP needs to shift towards crop diversification and water conservation techniques like System of Rice Intensification (SRI). The Western Plateau and Hills require investments in irrigation infrastructure, soil conservation measures (like contour bunding), and promoting drought-resistant varieties. The National Mission for Sustainable Agriculture (NMSA) focuses on promoting sustainable agricultural practices, benefiting both regions.

Conclusion

In conclusion, the cropping patterns of the Middle Gangetic Plain and the Western Plateau and Hills are shaped by their distinct geographical and climatic conditions. While the MGP benefits from fertile soil and reliable rainfall, it faces issues of soil degradation and water depletion. The Western Plateau and Hills, on the other hand, grapple with water scarcity and soil erosion. A shift towards sustainable agricultural practices, coupled with targeted interventions, is crucial for ensuring food security and improving the livelihoods of farmers in both regions.

Key Definitions

Kharif Crop
Kharif crops are sown with the onset of the monsoon season (June-July) and harvested in the autumn (September-October). Examples include rice, maize, and soybeans.
Rabi Crop
Rabi crops are sown in the winter season (October-November) and harvested in the spring (March-April). Examples include wheat, barley, and mustard.

Examples

System of Rice Intensification (SRI)

SRI is a methodology that significantly increases rice yields while reducing water usage and input costs. It involves transplanting young seedlings widely spaced apart and using organic fertilizers. It is gaining traction in the MGP.

Contour Bunding in Western Ghats

Contour bunding is a soil conservation technique used extensively in the Western Ghats to prevent soil erosion and conserve water. Bunds are constructed along the contours of the land, creating small dams that trap rainwater and reduce runoff.

Frequently Asked Questions

Why is the rice-wheat cropping system unsustainable in the MGP?

The continuous cultivation of rice and wheat depletes soil nutrients, leads to waterlogging, and increases the reliance on chemical fertilizers and pesticides, ultimately degrading the soil and impacting groundwater levels.

What are the main differences in soil types between the two regions?

The MGP has predominantly alluvial soils, while the Western Plateau and Hills have a diverse range of soil types including red, black, laterite, and forest soils, each with varying fertility and drainage characteristics.
