Vulnerability and Adaptation to Climate Change for Bangladesh
We collected primary data from Atulia and Padmapukur unions of Shyamnagar upazila under Satkhira district of Bangladesh in April We collected secondary data from published statistics. We did not find significant changes in temperature and rainfall over time but salinity level has increased over time.
Processes, Assessment and Effects
Major vulnerability faced by farming communities due to climate change were saline water intrusion, scarcity of safe drinking and irrigation water, and problems on crop production, livestock rearing, fresh water fish culture, and sanitary latrines. Major adaptations practiced by farmers were culturing saline water shrimp in farms, harvesting rain water, drinking ponds water, catching fish from the sea and river, and desalinization of river water by constructing embankments. Agricultural adaptation practices such as saline tolerant rice varieties cultivation, crabs fattening, sowing and planting date shifting, mulching, soil flashing, fertilizers management, seeds sowing using dibbling method, raise or slopping bed method crop cultivation in embankments, pit method crop cultivation, changing cropping patterns, zero tillage, and sorjan method crop cultivation can helps minimize the impacts of climate change, particularly to vulnerable smallholder farmers.
You can find more information in our data protection declaration. Bangladesh is one of the countries most vulnerable to climate change.
Extreme weather events there have already been wreaking havoc on the people there. They're also causing a shift in migration and poverty patterns. In August , 6. The totally submerged land constituted over 16, hectares, while another , hectares of crops were partially damaged.

That's not an isolated occurrence. In April the same year, floods wreaked havoc on Bangladeshi farmers, damaging around , hectares of ready-to-be harvested crops, according to the UN Food and Agriculture Organization. Official estimates suggest that in alone, the floods severely affected the livelihoods of at least eight million people living in Bangladesh. During the monsoon season every year, between June and September, Bangladesh faces flash floods.

But floods are not the only problem Bangladesh faces. Germanwatch, a Bonn-based environmental NGO, estimated that people died in Bangladesh last year due to extreme weather related events - floods, landslide, storms and cyclones.
Facing Climate Change in Bangladesh
In a new global index, Bangladesh has been ranked seventh among the countries most affected by extreme weather events in 20 years since The index is part of a report, Global Climate Risk Index , which was recently released at the annual climate summit in Poland's Katowice city. The report was prepared analyzing damages caused by the extreme weather events that took place from to It does not tell a lot," Rahman argued. Bangladesh has been one of the fastest growing economies in the world over the past several years, with the nation's economy expanding by an average of percent over the past decade.
The government is attempting to boost growth further and targeting double-digit expansion in the coming years. But some economists say climate change-linked problems are likely to act as a drag on the nation's growth prospects.

The study pointed out that Bangladesh would face annual economic costs equivalent to about 2 percent of its GDP by , widening to 9. The reasons for these losses, according to ADB, include an immense loss of crops, land, internal migration and salinity, among other things. But in Bangladesh, due to climate change, economic development requires comparatively more resources and investment.
This also adds to economic loss," said Raihan. Raihan also pointed out that climate-related catastrophes are causing a shift in migration and poverty patterns in Bangladesh. Farmers in the affected regions have started creating floating gardens with organic material where vegetables can be grown. Farmers create floating rafts on floodwater using water hyacinth, bamboo, cow dung, dirt, soil and other composts. Such rafts shift their position along with the water level and remain afloat for a period long enough to grow vegetables.
Farmers cultivate summer and winter vegetables such as gourd and okra as well as other leafy vegetables on their floating gardens.de.cejetoxe.tk

The method is cheap and sustainable, according to the country's agriculture experts. Such boat schools have been in operation for almost a decade, especially in the northern part of the country. Boat schools are equipped with computers that have an internet connection. Local non-government organizations offer solar lamps to students for home use in areas without electricity. They travel from place to place following the river routes.
Climate change poses dire challenges for Bangladesh
The tradition is on the decline but might make a comeback as a method of adapting to climate change. Experts consider initiatives like floating gardens and boat schools as small solutions to a big problem. Some islands are at the risk of disappearing completely under the rising seawaters. Therefore, the country needs a strategy to combat as well as to cope with climate change.
