River Erosion and Floods Are Increasing Due to Climate Change

The whole world is experiencing environmental disaster. Floods, cyclones and wildfires have burnt vast forests. Heavy rains, lack of rains, landslides, desertification, and droughts have increased manifold. This climate change has also affected Bangladesh.

In this land of six seasons, except summer, monsoon and winter, the rest have disappeared. Southern regions devastated by natural cyclones like Sidor, Aila, Yaas. The sea level rises and the embankments break and the coast is damaged by salt water.

Every year, the northern region is repeatedly submerged in torrential water. Thousands of kilometers of land, homesteads, farms are disappearing under the water of floods and erosion.

The only cause of climate change is excess carbon dioxide in the air and the absence of sufficient trees to absorb excess carbon dioxide. A country needs 25 percent forest land. We have far less than 17 percent. What is there is again arbitrarily deducted.

On the other hand, factory smoke, cooking, car smoke, air conditioners, refrigerators, etc. are regularly polluting the environment by releasing carbon. In contrast, the negligence is noticeable like Bhutan to greening to reduce carbon dioxide emissions.

Developed countries are releasing more carbon dioxide into the air. But they are not making adequate arrangements for excretion. Cold countries use the greenhouse process. Greenhouse process is a house made of glass. Plants die in overwintering in cold countries; Due to which glass houses are used.

This method is able to retain the sunlight during the day even in hot nights. As a result, the world is getting warmer day by day. The ice caps of several mountains including the Himalayas have started melting. Due to the impact of climate change - India's excess rains in monsoons and Himalayan melting ice water storms towards the ocean.

The flood situation has worsened in the northern region for the past few days. It is wrong to say only deterioration. Because the erosion situation in this flood is more worrying than before.

Hundreds of houses have been submerged after the collapse of the Teesta dam. Croplands, mosques, clinics are disappearing due to the erosion of Jamuna. Endangered people have taken refuge on higher ground, on embankments and in shelters.

Houses, cows and goats have been in the water of the stream. It has also affected the life and livelihood. Roads and roads are heavily damaged by flood water, ditches are filled. The communication system is facing collapse. Sudden excess rainfall due to climate change; The water of the rain fell upstream and this has brough bed luck for the people of the river bank. Some are sitting with their hands on their foreheads after losing their last possessions.

Our major rivers flow through the neighboring states of India. They have built a dam on the river. Especially the Farakka Dam on the Padma, the Teesta Dam on the Teesta and the Tipaimukhi Dam on the upper reaches of the Brahmaputra.

At other times, these dams are blocked. It is released only during the monsoon when the water in the sluice is under pressure. As a result, villages are suddenly washed away by huge floods. Most of the regions are flooded. The homestead is washed away with the flow of water.

The rivers are not navigable due to dams. Many riverbeds have died due to lack of water for a long time. Most of the small and big rivers and even canals have been occupied by encroachers due to drying up. If the water storage medium dies or becomes occupied, where will the water created due to climate change go out? Obviously, it will come down from the locality due to the river's sudden crisis.

Erosion will occur naturally if the dry river suddenly rises above the danger level. If the dams are not built or could be opened before the specified water pressure is reached, poor people do not have to face this kind of suffering every year.
