Agriculture in Bangladesh continues to be affected by nature and climate change, including floods, droughts, salinity and cold winds. The reason is the long rainless nature.
Haor area of Netrokona and Kishoreganj and Boro paddy in several areas of 36 districts of the country including Gopalganj, Narail, Kushtia, Rajshahi, Mymensingh as well as maize, vegetables, peanuts, sunflower and banana crop lost a total loss of Tk 334 crore. Of this, Boro paddy has suffered a loss of Tk 328 crore, maize has lost about Tk 4 crore and the number of affected farmers stands at 3.10 lakh.
According to the Department of Agriculture, 48,000 hectares of Boro paddy has been affected by the heat shock. During the Boro season last year, the temperature and humidity were at a tolerable level during the flowering stage of paddy, so the chita (Malnourished rice) problem of Boro paddy was not so obvious. The new crisis in Corona is making everyone think about food security.
According to the rice researchers, the temperature and humidity were tolerable during the flowering stage of the paddy in the Boro season last year, so the chita problem of Boro paddy was not so obvious. But due to lack of rainfall in the current Boro season, the temperature was increasing day by day and the amount of humidity in the air was decreasing due to relevant reasons. In this situation, the recent drought in different parts of the country with no rain has resulted in the drying up of paddy stalks in the areas where the paddy was in full bloom. The air temperature was about 36 degrees Celsius in the rainless intense heat. As a result, their pollen dries and the paddy becomes sticky.
Meteorologists say that if there is water in the Haor area and there is heat from the sun, the amount of water vapor increases a lot. If there is more water vapor and there is no wind speed, we may have a record of 36 degrees Celsius, but the feeling of temperature can be more than 40 degrees Celsius. If the amount of water vapor in the air is more than 70 percent and the wind speed is less than five kilometers per hour, then the perceived temperature is much higher than what we measure, which has happened in the Haor area, which is harmful to crops. The only way to protect the paddy from this loss is to adjust the sowing and planting time based on the life span of the paddy in such a way that such intense heat of Kalbaishakhi can be avoided during flowering of the paddy.
