The Indian summer monsoon plays a vital role in sustaining agricultural production, water resources, and food security in India. Nearly 70–80% of the country’s annual rainfall occurs during the monsoon season (June–September), making agriculture highly dependent on the timing, intensity, and distribution of rainfall. This study examines the long-term trends in Indian monsoon rainfall from 1951 to 2025 and evaluates their implications for agricultural productivity. Secondary rainfall data from the Indian Meteorological Department (IMD) and published climate research were analyzed to understand temporal and spatial rainfall variability. The findings indicate that while total seasonal rainfall shows relatively weak long-term trends at the national scale, there has been a significant increase in the frequency of extreme rainfall events and regional variability in rainfall distribution. These changes have affected agricultural practices, crop productivity and rural livelihoods, particularly in rain-fed regions. The study highlights the importance of climate-resilient agricultural strategies, improved rainfall forecasting, and sustainable water management practices to reduce the vulnerability of Indian agriculture under changing monsoon conditions.
