Question

The IMD collates rainfall between June and September as SW monsoon. Answer the following question.

The southwest monsoon typically accounts for about 70% of India’s annual rainfall, making it vital for the country’s agrarian economy, which contributes approximately 14% to the national GDP. A good monsoon would boost the economy, how?

Answer 1

A good southwest (SW) monsoon boosts India’s economy primarily through its positive impact on agriculture, water availability and related sectors.

1. Agriculture Output: The SW monsoon accounts for about 70% of India's annual rainfall, which is crucial for rain-fed agriculture. Good monsoon rains ensure adequate soil moisture, resulting in better crop yields. Since agriculture contributes around 14% to national GDP and supports the livelihood of a large part of the population, a good monsoon leads to increased agricultural productivity and income for farmers.
2. Water Availability: Adequate monsoon rainfall replenishes surface water sources such as rivers, lakes, and reservoirs, and also recharges groundwater aquifers. This availability of water is essential for irrigation in agriculture as well as for drinking water and industrial use.
3. Economic Multiplier Effect: Higher agricultural output increases demand for inputs like seeds, fertilizers, and machinery, benefiting related industries. It also boosts rural consumption and spending, stimulating economic growth in the rural economy and beyond.
4. Hydro and Power Generation: Monsoon rains fill dams and reservoirs, which are used for hydroelectric power generation, thus supporting energy needs.
5. Climatic Balance: Good monsoon rains moderate temperatures and help maintain ecological balance, supporting fisheries and other natural resources dependent on water.
