Bangladesh will suffer more from climate change than any other country in the world. Its effects have already begun to read. "Bangladesh is at extreme risk," world experts agree. There is no way we can deal with this risk. There has been a lot of fuss in seminars or newspapers about how the preparation should be, but in practice no application is being noticed.
*Status of Bangladesh:
The reason is the geographical location. Due to being riverine, the soil of Bengal is fertile. No other country in the world like Bangladesh has so many rivers, canals, beels and haors. Due to these, it has had an inevitable effect on the public life, soil and climate of Bengal.
*Features:
Bangladesh is a seasonal wind dependent country. Monsoon winds cause monsoon in Bangladesh. In Bangladesh, the monsoon is controlled by its cultivation, livelihood, trade and commerce. When the monsoon occurs in Bangladesh as required or in moderation, it is a blessing. And when it occurs in excess of the need, it is a curse. Excessive rainfall is excessive rainfall. Floods come from heavy rains, and if there is no rain again, there is drought. Both of these are harmful and catastrophic for the country. Floods destroy crops, and droughts burn crops. This affects the drinking water from food grains. This led to famine. Apart from this, the violence and tidal wave of Kalbaishakhi became the cause of disaster.
*Disadvantages of Bangladesh:
Apart from natural disasters like rains, droughts, floods, storms and tidal waves, the biggest crisis that will be created in the long run is that 18 percent of the southern part of Bangladesh will be submerged and 20 million people will be homeless. As a result of the adverse impact on livelihoods, the losses that Bangladesh will face cannot be covered by money.
*Our Climate Change:
Climate change in a place means an average of at least 30 years of change in one of the climate issues. The most important regulator for measuring climate change is the change in night temperature. Because the traffic and factories are closed at night. Then the earth starts losing its stored temperature. Climate change can be calculated with the temperature at that time. The perimeter of our winter is getting smaller. From the temperature we have calculated for 21 places in the last 56 years, we can say that the length of winter has become shorter. Average rainfall remains unchanged, but the number of more rainy days and days without rain is increasing. This effect is more prevalent in the north-western part of the country. Note that a study found that before the rains there was a probable condition, in the last half of July and the first half of August it has now expanded to the rains from the last half of June to 10 days of July. And the rest of the rain is going away in the last half of August. Rainfall is not what it is supposed to be. So the time when the flood is supposed to happen or the time when people are ready to deal with the flood is being disrupted. As a result, the amount of damage is increasing. So it is having a detrimental effect on our agriculture. Many cyclones have hit recently. The magnitude of the cyclones has increased. Increasing the intensity of cyclones in our coastal defense dams is causing coastal areas to be damaged by strong waves. The salinity water is entering the agricultural land and the agricultural system is collapsing.
*Coastal areas:
Where salt water is being mixed with fresh or freshwater, water density is changing. As the amount of sedimentation in the river increases, the water of the river will overflow and cause waterlogging. As a result, the amount of waterlogged area will increase. As the sea surface temperature rises, the lower pressures will become stronger and cause cyclones. 20 years ago, the average pressure in the Bay of Bengal was not more than five to six. Now there is an average of 12 to 14 depressions a year. As a result, fishermen are not able to fish in the deep sea for a long time during the monsoon season. Having to return to shore due to repeated storm warnings. As a result, their profession is being damaged.
*Things to do:
The government has to take an integrated plan on all issues including agriculture, food, health infrastructure by making a climate-risk map of every region of the country. Local government needs to be more involved. Priority plans need to be adopted to address local issues, taking into account the views of locals. Forecasting system needs to be developed in agriculture like weather. No proper plan for curriculum development has been adopted so far. It will not be possible to protect the country from the harmful effects of climate change if we do not make our student society efficient and aware. Teachers need to increase their skills. Compared to the amount of research data released by private organizations on climate change, no such research has been released from public universities. Community based and adaptation measures have to be taken. The seeds of such crops have to be spread everywhere to adapt to the adverse environment. Infrastructural development needs to be done in the coastal areas. Arrangements will have to be made for construction and rehabilitation of new shelters.
Once upon a time, people had the idea that the most important thing is to establish dominance over nature by any means. Today that perception has changed. Because it is seen that in order to establish this domination, by destroying the forest, stopping the flow of the river, disturbing the balance of the environment, people have brought danger for themselves. So today, not domination over nature, people want to build a friendly relationship with nature. And trying to maintain the balance of nature with the help of nature to lead his own way of life towards the beautiful future of the future.
Wow really good
