Q.What characteristic can be assigned to monsoon climate that succeeds in feeding more than 50 % of the world population residing in monsoon Asia?

UPSC Mains 2017Geography

Introduction

The monsoon climate, prevalent in monsoon Asia (South, Southeast, and East Asia), is characterized by seasonal rainfall driven by the interaction of land and sea. This climate is a lifeline for more than 50% of the world’s population living in this region, as it sustains agriculture, water resources, and livelihoods.

Body Analysis

Key Characteristics of the Monsoon Climate

  • Seasonality of Rainfall:
    • Monsoon climate features distinct wet and dry seasons. The wet season provides abundant rainfall essential for crops like rice, which thrives under water-intensive conditions.
    • Example: India receives 75-90% of its annual rainfall during the Southwest Monsoon (June-September).
  • High Rainfall Intensity:
    • The monsoon brings intense and concentrated rainfall, crucial for recharging rivers, aquifers, and reservoirs.
    • Example: Cherrapunji and Mawsynram in India are among the wettest places on Earth, receiving more than 11,000 mm of annual rainfall.
  • Geographic Variation:
    • Rainfall distribution is uneven, influenced by geographical features like mountains and plateaus, which creates diverse agro-climatic zones suitable for different crops.
  • Winds Reversal:
    • The complete seasonal reversal of wind direction (south-west in summer and north-east in winter) ensures different regions receive rainfall at different times of the year, supporting multiple cropping cycles.
  • Agricultural Dependency:
    • The timing of the monsoon onset is highly critical. A timely monsoon ensures successful sowing of Kharif crops, which form the food security backbone of the region.

Conclusion

The monsoon climate's unique blend of high-intensity, seasonal, and widely distributed rainfall makes it uniquely suited to support intensive subsistence agriculture, particularly paddy cultivation. This high agricultural productivity is the primary reason why monsoon Asia can sustain and feed more than half of the global population.
