What effects will climate change have on Bangladesh?

Question

positive and negative effect climate change will make to Bangladesh? thankyou!!

Answer 1

*FLOSSIE I never said there was a single flood Maybe you should learn to read English before you accuse someone to not be trustworthy.. At least I understand global climate change Your remark was rude considering I never made that statement!!



Well Bangladesh has already experienced a sea level rise in the bay which has caused flooding and an increase in storm level there. This will get worse as time goes on.



As far as I know there have been, and and we aren't likely to see any positive effects

Answer 2

I think bangladesh is normal quandary nation, angladesh lies within the northeast of the Indian subcontinent on the Bay of Bengal. It's a predominantly low-mendacity nation with a number of most important rivers placed in general within the huge delta formed through the Brahmaputra and Ganges Rivers. The population density is ready one thousand persons per rectangular kilometer, some one hundred fifty million humans live in an discipline of 148,000 rectangular kilometres Bangladesh has a tropical local weather, it's humid and heat during the year with a yr round traditional temperature of 25°C. Rainfall is reasonable to excessive across the nation and degrees from 1400mm along the eastern border to 5100mm in the northeast. Lots of the rain falls for the duration of the monsoon season and from June to October flooding is normal. There are two cyclone seasons which is able to carry devastating winds and tidal surges. The early season is in April and could at the same time the late season lasts from September to November...Thanks !!!

Climatic Impacts:



Bangladesh experiences different types of Natural Disasters almost every year because of the Global Warming as well as Climate Change impacts, these are:



Floods / Flash Floods (Almost 80% of the total area of the country is prone to flooding).



Cyclones and Storm Surges (South and South-eastern Parts of the country were hit by Tropical Cyclones during the last few years).



Salinity Intrusion (Almost the whole Coastal Belt along the Bay of Bengal is experiencing Salinity problem).



Extreme Temperature and Drought (North and North-western regions of the country are suffering because of the Extreme Temperature problem).



Agriculture and Fisheries:



As already mentioned earlier, the economy of Bangladesh is based on Agriculture mainly, with two thirds of the population engaged (directly or indirectly) on Agricultural activities; although the country is trying move towards industrialization slowly during the last one and a half decade almost. So, the overall impact of Climate Change on Agricultural production in Bangladesh would be wide spread and devastating for the country’s economy. Beside this, other impacts of Climate Change such as - Extreme Temperature, Drought, and Salinity Intrusion etc. are also responsible for the declining crop yields in Bangladesh. Temperature and Rainfall changes have already affected crop production in many parts of the country and the area of arable land has decreased to a great extent. The Salinity intrusion in the coastal area is creating a serious implications for the coastal land that were traditionally used for rice production.



The fisheries sector has also experienced an adverse affect because of the impacts of Climate Change. The fisheries sector contributes about 3.5% of the GDP in Bangladesh and people depend on fish products in order to meet up majority of their daily protein requirements. There are around 260 species of fish in the country and almost all the varieties are sensitive to specific salt and freshwater conditions.



Water Resources and Hydrology:



In a high density country like Bangladesh, the effects of Climate Change on the Surface and Ground water resources will be very severe and alarming. Changes to water resources and hydrology will have a significant impact on the country’s economy, where people mostly depend on the Surface water for Irrigation, Fishery, Industrial production, Navigation and similar other activities.



Coastal Areas:



Almost one forth of the total population of the country live in the coastal areas of Bangladesh, where majority of the population are some how affected (directly or indirectly) by Coastal Floods / Tidal Surges, River-bank Erosion, Salinity, Tropical Cyclones etc. With the rise of Sea-level up to one meter only, Bangladesh could lose up to 15% of its land area under the Sea water and around 30 million people living in the coastal areas of Bangladesh could become Refugees because of Climate Change impacts. Agriculture, Industry, Infrastructure (School, Hospitals, Roads, Bridges and Culverts etc.), Livelihoods, Marine Resources, Forestry, Biodiversity, Human Health and other Utility services will suffer severely because of the same. Salinity Intrusion from the Bay of Bengal already penetrates 100 kilometers inside the country during the dry season and the Climate Change in its gradual process is likely to deteriorate the existing scenario to a great extent. Since most of the country is less than 10 meters above Sea level and almost 10% of the population of the country is living below 1 meter elevation - the whole coastal area is Highly Vulnerable to High Tides and Storm Surges. Moreover, the Bay of Bengal is located at the tip of the north Indian Ocean, where severe Cyclonic storms as well as long Tidal waves are frequently generated and hit the coast line with severe impacts because of the Shallow as well as Conical shape of the Bay near Bangladesh.



Forestry / Biodiversity:



Bangladesh has got a wide diversity of Ecosystems including Mangrove forests at the extreme south of the country. The “Sundarbans” a World Heritage, is the largest Mangrove Forest in the world, comprising 577,00 ha of land area along the Bay of Bengal. A total of 425 species have been identified there, the most significant is the famous Royal Bengal Tiger. Therefore, Climate Change impacts will have negative effects on the Ecosystem of the Forest recourses in Bangladesh while the Sundarbans is likely to suffer the most.

Answer 4

Its really very Bad ... What I know most of the Sundarbans will submerge under sea and people will be forced to shift from lower Bangladesh to upper Bangladesh.... We should stop it now every one should try to reduce carbon foot print.

Answer 5

As Bog Syph has said, Bangladesh has experienced its first ever flood.

Judging him by this revelation, I leave it up to you whether or not to trust his other pronouncements.



EDIT @ Trevor: Some time ago I asked to be told of any "climate change refugees" anywhere, I was not informed of any.

Why then, esteemed scholar, do you bring up this myth that people in Bangladesh have been displaced by rising sea levels?

Everyone knows that riverine islands in Bangladesh come and go.

However, it is also probable, that the island disappeared in a natural process of the channel dynamics rather than climate change as hypothesized by Dr. Hazara. The appearance and disappearance on char (river islands) is common in Bangladeshi rivers. In some cases they re-emerge after some years.

Answer 6

The Climate of Bangladesh

¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

Bangladesh lies in the northeast of the Indian subcontinent on the Bay of Bengal. It is a predominantly low-lying country with several major rivers located mainly in the large delta formed by the Brahmaputra and Ganges Rivers. The population density is about 1000 persons per square kilometre, some 150 million people live in an area of 148,000 square kilometres



Extensive deforestation, largely of teak, kapok and banyan, has reduced forest cover to about 10% of the land area. Coastal forests, mainly mangroves, have extended roots that stabilize the coasts and prevent erosion, the destruction of these habitats has led to accelerated erosion along some coastlines.



Bangladesh has a tropical climate, it is humid and warm throughout the year with a year round average temperature of 25°C. Rainfall is moderate to high across the country and ranges from 1400mm along the eastern border to 5100mm in the northeast. Most of the rain falls during the monsoon season and from June to October flooding is common. There are two cyclone seasons which can bring devastating winds and tidal surges. The early season is in April and May whilst the late season lasts from September to November.





Climate Change in Bangladesh

¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

There are already many complex environmental problems facing Bangladesh including air, soil and water pollution, depletion of natural resources, desertification, droughts, energy shortages and land contamination. Climate change is exacerbating the already stressed conditions .



As temperatures rise there has been an increase in the frequency of heat-related conditions such as hypoxia and heat stroke. The higher temperatures have increased concentrations of ground level ozone, this has caused more respiratory conditions. There has been an increase in the incidence of disease carrying vectors which has seen more cases per capita of a wide range of diseases.



Instances of flooding have increased and this had led to crop destruction and water contamination, which in turn spreads diseases such as cholera and typhoid along with other water-borne diseases.



One of the biggest threats facing Bangladesh comes from rising sea-levels. The extensive low-lying areas are more prone to flooding than ever before and large numbers of people have already been evacuated; half a million alone from Bhola which is now semi-submerged.



Sea-levels in the Bay of Bengal are rising by 5.3mm a year compared to the global average of 3.2mm. The most recent and extensive studies of sea-level rise predicts that by 2100 there will have been a 1400mm rise in sea-levels, this would displace about 30 million people and lead to the permanent loss and abandonment of about one fifth of the land, most notably in the delta region of the Ganges.



An increase in seasonal flooding has already been observed, the annual floods now last longer, the land drains slower and ground water is becoming increasingly salinated; this trend is set to continue into the future.



With rising sea-surface temperatures the threshold at which cyclones are spawned will be reached more frequently and it’s highly likely that Bangladesh will suffer an increase in the frequency and intensity of tropical cyclones.

EDIT: TO FLOSSIE



I noticed that you’ve now asked a specific question about Bangladesh and climate change refugees, please see my response to that question.

Answer 7

they already have lots of flooding and monsoons ,so it will get worse
