CLIMATE CHANGE AND BANGLADESH
or,
THE IMPACT OF CLIMATE CHANGE IN BANGLADESH
Introduction : Climate change has become a major global concern nowadays. Especially the developing and underdeveloped countries of the world are being seriously affected by it. These countries contribute to climate change the least but suffer for it the most.
What is climate change: Climate change is the changes in the earth’s weather including changes in temperature wind patterns and rainfall. But especially it refers to the increase in the temperature of the earth’s atmosphere caused by the rise of particular gases. These gases include mainly Carbon dioxide, Methane, Colorful or carbons (CFCs), and oxides of Nitrogen and Super.
How is climate change caused: The particular gases responsible for climate change are called greenhouse gases. Due to the destruction and burning down of tropical rain forests, increasing use of fossil fuels, the rapid growth of industry, and the use of CFCs in packaging. As a result, heat is being trapped increasingly in the atmosphere which causes climate change.
Bangladesh and Climate change: Bangladesh is under the serious threat of climate change. Already the country has had bitter experiences of climate change. The threats lying ahead for this change are described below briefly:
1) Threat of flood: According to the Intergovernmental Panel on Climate Change (IPCC), the sea level of the Bay of Bengal will increase by about 100 CM by 2100 due to climate change. Such a rise in the sea level will flood nearly 17% of our total land area. This will destroy physical infrastructure of the flooded area and one-fifth of our total population will be homeless.
2) Frequency of natural calamities: As a result of climate change, Bangladesh has been affected by frequent natural calamities during the recent years. these calamities include floods, cyclones, tidal bores, excessive rainfall, riverbank erosion, drought, etc. Bangladesh experiences an intense flood almost every four years, Besides, there are floods with lesser magnitude. On the other hand cyclones like ‘Sidr’, Nargis, ‘And Aila’ have become regular nightmare experiences for the people of coastal areas. These cyclones are often associated with tidal bores. Droughts of various magnitudes also affect 20-46 percent land of Bangladesh every year.
3) Decreasing food production: According to IPCC, the average temperature of Bangladesh will be increased up to 2 degrees Celsius by 2050. As a result, sea-level will rise which will increase salinity in inland rivers. Experts fear that this increased salinity along with the shortage of water for irrigation will decrease the production of rice up to 10% and wheat up to 30%.
Ultimate result of climate change in Bangladesh: If the present rate of climate change continues, there will be no country in the world map called Bangladesh. The whole country will go under seawater and there will be no sign of the present flora and fauna.
What to do face climate change: Climate change is such a problem in the world that it must be addressed unitedly by in all the countries of the world. But at our national level, we immediately should stop deforestation and start afforestation. At the same time, we should keep ourselves up to-date with the international community regarding our strategy to fight against climate change.
Conclusion: The world has been faced with the threat of extinction due to the problems of climate change. If effective steps are not taken to stop this change, the world will no more be inhabitable. So, it is high time we all including the international community took concerted steps against climate change.
