Importance of Summer Rainfall in Indian Agriculture
India heavily relies on monsoon rainfall for its agricultural activities, and summer rainfall plays a crucial role in this regard.
Contribution to Total Annual Rainfall
- Summer rainfall accounts for almost 70% of India's total annual rainfall.
- This makes it a primary source of water for agricultural activities in the country.
Timing for Summer Crops
- Summer rainfall is essential for sowing and cultivation of various summer crops like rice, sugarcane, cotton, and pulses.
- These crops require adequate water during their growth stages, which is fulfilled by summer rainfall.
Replenishing Groundwater
- Summer rainfall helps in replenishing groundwater levels, which is essential for irrigation during the dry seasons.
- It ensures a continuous water supply for crops even when monsoon rainfall is insufficient.
Impact on Rural Economy
- Successful summer rainfall leads to a bountiful harvest, which directly impacts the rural economy.
- It ensures food security and income generation for millions of farmers across the country.
Conclusion
In conclusion, summer rainfall is a lifeline for Indian agriculture due to its significant contribution to the total annual rainfall, support for summer crops, groundwater replenishment, and positive impact on the rural economy. Its importance cannot be overstated in ensuring the sustainability and productivity of the agricultural sector in India.

Rahul Choudhury answered |
Crop yield will decrease due to decreased water availability and new pest incidence. The Third Assessment Report of the IPCC in 2001 concluded that climate change would hit the poorest countries severely, reducing agricultural products. Crop yield would be reduced in most tropical and subtropical regions due to decreased water availability and new or changed insect/pest incidence.
