As the world’s second-most populous country, India plays a critical role in feeding the global population. The agriculture sector is a vital component of India’s economy, employing over 50% of the workforce and contributing 18% to the country’s Gross Domestic Product (GDP). However, climate change has been casting a long and ominous shadow over Indian agriculture, threatening the livelihoods of millions of farmers and the food security of the nation. Rising temperatures, unpredictable weather patterns, and extreme events such as heatwaves and floods are altering the very fabric of Indian agriculture, making it imperative to understand the impact of climate change on this vital sector.
Unseasonal Weather Patterns and Crop Failures
India’s agriculture sector is heavily reliant on monsoon rains, which account for over 70% of the country’s annual rainfall. However, climate change has been disrupting this delicate balance, leading to unpredictable and unseasonal weather patterns. Rising temperatures are causing earlier monsoon onset and delayed withdrawal, leading to crop failures, reduced yields, and increased pest and disease pressure. The 2019 heatwave, which affected over 20 states in India, resulted in a significant decline in wheat and paddy production, exacerbating the country’s food insecurity concerns.
Changing Pest and Disease Dynamics
Climate change is also altering the dynamics of pests and diseases that affect Indian crops. Warmer temperatures and changing precipitation patterns are creating an environment conducive to the proliferation of pests and diseases, leading to reduced crop yields and decreased productivity. For instance, the warmer and wetter conditions have led to an increase in the spread of diseases such as leaf rust and rust diseases in wheat, reducing yields by up to 20%. Similarly, the rise in temperatures has led to an increase in the population of pests like aphids, nematodes, and whiteflies, further damaging crop yields.
Soil Degradation and Erosion

The intense rainfall events and heatwaves are leading to soil erosion, reducing its fertility and affecting its water-holding capacity. Additionally, the altered weather patterns are causing an increase in soil salinization, which is affecting the productivity of many agricultural regions. The loss of soil health can have long-term consequences for agricultural productivity, making it essential to adopt sustainable agricultural practices that mitigate the impact of climate change on soil health.
Adapting to the New Normal
The impact of climate change on Indian agriculture is undeniable, and it is imperative that the sector adapts to the new normal. This can be achieved by adopting climate-resilient agricultural practices, such as drought-tolerant crops, agroforestry, and conservation agriculture. Additionally, the promotion of organic farming and the use of bio-fertilizers and bio-pesticides can help reduce the sector’s reliance on chemical inputs. Furthermore, the development of early warning systems and climate information services can enable farmers to make informed decisions about planting, irrigation, and pest management. By adopting these measures, India can build a more climate-resilient agriculture sector, ensuring the food security and livelihoods of its growing population.
