What are the expected consequences of Global Warming in Bangladesh?

Posted at: 2015-03-12 
Impacts of climate change in Bangladesh

1. Disappearing seasons of Bangladesh

There are six seasons in Bangladesh which are disappearing due to climate change. Summer & rainy seasons are prolonging, whereas winter season is shrinking. Autumn and Dewy seasons are vanishing. Spring season has already been vanished.

2. Infrastructures

In Bangladesh, 93 disasters have occurred over the period from 1991 to 2000 and incurred the loss of US$ 590 crore in agriculture and infrastructure sectors.

3. Saline water intrusion

About 830,000 ha cultivable land has damaged by saline water intrusion from Bay of Bengal.

4. River bank erosions

Near about 106,300 ha river bank has eroded over the period from 1982 to 1992 due to climate change induced hazards especially floods.

5. Drought/too little water during the dry season

About 21.8 tones of rice damaged due to drought over the period from 1973 to 1987.

6. Floods/too much water during monsoon

Rice, about 23.8 lack tones has damaged due to flood over the period from 1973 to 1987.

Future Projection of Climate Change Impacts in Bangladesh

1. Crop production & food security

Rainfall patterns are changed due to climate change – crops yields are expected to drop significantly. Crop production will decrease 30% in 2100. Production of rice & wheat will reduce 8.8%, and 32% within 2050 respectively.

2. Salinity

There are 13% areas are salinity at Bagerhat, Khulna & Sathkhira, the southwestern coastal districts of Bangladesh at present which will increase 16% in 2050 and 18% in 2100.

3. Coral bleaching

Corals are vulnerable to thermal stress. If the sea surface temperature increases 1-3° C then corals bleaching will occur frequently.

4. Mangrove forest

About 75% area of mangrove forest, Sundarban (60007 Sq. km) will submerse if the sea level will increase 45 cm. If the sea level rise 1 m then the islands of Bay of Bengal and whole Sundarban will destroy including its fauna & flora.

5. Fisheries:

? Death rate of shrimp’s fingerlings will increase if the water temperature is more than 32°C (CEGIS).

? Diseases of fish may increase.

? Carps culture may reduce due to saline water intrusion in the ponds and open water bodies.

? Production of sweet water fish will shrink and extinct if the sea level rise.

Next year (which would be long range weather prediction and not a global warming question) or in a hundred years (which would be climate?)

Also, it would involve questions of politics. India controls a lot of dams sitting on rivers they can open at will to flood into Bangladesh. And, in fact, they do that if they feel their dams are threatened. So predicting politics will have a lot to do with any even slightly realistic attempts at answers, both short and long term. And of course... location within Bangladesh.

Your question is overbroad and any answer would fill at least one book, if not more.

Bangladesh is a special situation, unlike other places, because even a minor sea level rise can cause damage there.

The problem is Bangladesh is a country built entirely on silt, which is continually building and eroding, it is also subsiding badly (sinking), the building of sea walls to prevent flooding, usually channels the tidal waters upstream and with greater height, causing flooding elsewhere.

Not an easy problem to solve, with or without climate change.

What global warming? It's been cooling for at least 12 years.
