The Department of Meteorological, the rainfall in the autumn has reduced rates too. The capital received 155 mm rainfall on Friday and yesterday on Saturday. If this amount of rainfall is kept in a container, its height will be approximately 16 centimeters. That means about 6 inches. The weatherman said that the rainfall was very less during this time.
The weather was in another look before this jumbo lasting for three days. The maximum temperature in most parts of the country, including the capital, for four-five days, has risen to 34 degrees to 37 degrees Celsius. Generally, this type of hot summer is felt. But for a big time in September this summer has been hot summer. This change of rainfall and temperature is not happening this year, but for 30 years. Local and foreign researchers see this as an effect of climate change. As a result, food production in the country is declining, new disasters are rising, diseases are spreading and large number of displaced people are also displaced.
Bangladesh University of Engineering and Technology (BUET) water and flood management institute has done a research on climate change in Bangladesh. Researchers of the company say, the untimely rain is due to climate change. Not only rains, the average temperature of Bangladesh is also rising like the world. In this way, the temperature of the country can increase from one and a half to two degrees Celsius in this century. Boro and aman paddy production may fall by 10 percent annually as the temperature increases to one and a half degrees Celsius. In other words, almost 40 million tons of food production could fall.
Two separate studies by the Department of Meteorology and Bangladesh Center for Advanced Studies (BCAS) have shown the change in the type of rainfall in the country. It has been found that, in the last 30 years, the department of Chittagong division has been growing in the country. The hills are growing in the area. On the other hand, in the southwestern part of the country, the rainfall is declining. Generally, the salinity of the saline area is decreasing due to the increase in water and soil salinity. As a result, the production of crops in the area is declining.
The United Nations Food and Agriculture Organization (FAO) recently warned eight countries of the world about food security risks. Meanwhile, FAO has blamed climate change for breaking the haor embankment in Bangladesh and for climate change due to large floods. The United States Agrarian Agency USDA’s report on the situation in Bangladesh in June also blamed the climate change as the reason for the decline in crop production this year.
Professor Saiful Islam, professor of water and flood management institute and climate research team, spoke about this. He said, “In Bangladesh so long we talked about the possible impact of climate change. Haor usually floods in April-May, this year we saw the horrific floods in March. The floods that took place in the northern part of the country in August-September, saw the highest level of water rise in the last 100 years. These are the effects of climate change. ‘
Bangladesh in danger
The fourth assessment report of the United Nations Intergovernmental Panel on Climate Change (IPCC) said that one-third of Bangladesh’s area could be submerged in this century. About 60 thousand square kilometers of the 19 districts of the country are in danger of drowning. As a result, nearly two million people could be displaced.
BUET’s new research has been presented in the study of how coastal people will be displaced in the sea level rise. Of course, there are fewer areas where the area is likely to sink. The study, led by professor Saiful Islam, found that in the century, if the height of the water of the Bay of Bengal increased by one meter, the country’s 3,930 sq km area could be drowned. Approximately 6 million people may be displaced from almost 4 percent of the country’s total land area.
Saiful Islam said in the first light, ‘The IPCC prediction was given to consideration of a global phenomenon. On the basis of approximation. We calculate the amount of water that has increased in the Bay of Bengal and its related rivers, especially in the last 30 years. If this trend continues, then I have done research based on the extent to which it can grow. ‘
This year’s report by the German watchdog German Watch, says that in the last 30 years, Bangladesh has been hit by 185 extreme extreme weather conditions, which is the third highest in the world. Between 1996 and 2015, Bangladesh has the fourth position among the countries with the most financial loss for the adverse weather. Bangladesh is the third country in terms of mortality due to hostile weather and Bangladesh
Catching rain in Chittagong
According to the Meteorological Department, in Chittagong division this year 70 percent more than normal. Especially in Sandwip, the total rainfall of the last three days has crossed 400 millimeters. In Cox’s Bazar, Teknaf, most parts of Chittagong division are getting more than twice the normal rainfall. Rainfall in Chittagong City created water logging, which stuck the life of the city people with tide-tide. Most of the time in July-August, the large part of the city of Chittagong was nearly stagnant. However, this is not the exception of the September rainfall, the latest study of climate change done by the Department of Meteorological Department.
