Spatio-Temporal Variability of the Indian Monsoon and Its Impact on Agricultural Productivity in India

The Indian summer monsoon is one of the most significant climatic phenomena influencing agricultural production and food security in South Asia. Nearly 70–80% of India’s annual rainfall occurs during the monsoon season (June–September), making agriculture highly dependent on its timing, intensity, and spatial distribution. Variability in monsoon rainfall due to climate change has resulted in increasing frequency of droughts, floods and extreme rainfall events, significantly affecting crop productivity. This study examines the spatio-temporal variability of the Indian monsoon and its impact on agricultural productivity using secondary data from meteorological datasets and agricultural statistics. Results from previous studies indicate that monsoon rainfall variability strongly influences crop yields, particularly rice and other major Kharif crops. Changes in rainfall onset, duration, and distribution disrupt sowing patterns and reduce crop yields in rain-fed agricultural systems.
