Rain in South Bengal: How does rain affect agriculture in South Bengal?

Rain is an essential factor for agriculture, as it provides water for irrigation and sustenance of crops. However, too much or too little rain can also have adverse effects on agriculture, especially in regions like South Bengal, where the climate is influenced by various phenomena such as monsoons, cyclones, and low-pressure systems. Here are some of the ways rain can affect agriculture in South Bengal:

• Rain can cause flooding and waterlogging of agricultural fields, which can damage crops and reduce soil fertility. Floods can also wash away nutrients and organic matter from the soil, making it less productive. According to a web search result, over 5 million hectares of crop area were affected due to heavy rains in India in 2021, out of which West Bengal accounted for 690,000 hectares.
• Rain can also cause droughts and water scarcity, which can affect crop growth and yield. Droughts can also increase the risk of crop failure and food insecurity. According to another web search result, India lost 35 million hectares of cropped area due to droughts between 2015 and 2021, which are likely to intensify due to climate change.
• Rain can also affect the quality and quantity of crop production, as it can influence the timing and duration of various stages of crop development. For example, high temperatures and low rainfall during the flowering stage can reduce the grain filling and increase the sterility of rice. On the other hand, excess rainfall during the harvesting stage can cause losses due to lodging, shattering, sprouting, and fungal infections.

• Rain can also bring saline sea water into farmlands through storm surges, which can affect soil quality and crop suitability. Salinity can reduce the availability of water and nutrients for crops, and increase the toxicity of certain elements. Salinity can also affect the germination, growth, and yield of crops⁴. For example, cyclone Nivar in 2020 caused salinity intrusion in coastal districts of Tamil Nadu, affecting rice cultivation.
• Rain can also cause pestilence and diseases, which can affect crop health and productivity. Pests and diseases can spread rapidly due to favourable conditions created by rainfall, such as high humidity, moisture, and temperature. Pests and diseases can also reduce the quality and marketability of crops. For example, erratic rains in 2021 caused outbreaks of pests such as brown plant hopper, stem borer, leaf folder, and blast disease in rice fields in West Bengal.

These are some of the ways rain can affect agriculture in South Bengal. To cope with these challenges, farmers need to adopt climate-resilient practices such as crop diversification, improved varieties, water management, soil conservation, integrated pest management, and crop insurance. The government also needs to provide timely and accurate weather information, contingency plans, relief measures, and policy support to the farmers.
