Global heating induced Climate Change might hold triggered the increased incidences of terrible catastrophes like cyclones and inundations over the coastal part of Bangladesh in the recent yesteryear with amplified figure of human deaths and greater economic loss. This paper investigates the possible relation between clime alteration induced catastrophes and rural poorness in the two south-western coastal territories of Bangladesh utilizing three indexs: income variableness, plus loss and migration. It was found that, due to recent inundation caused by tropical cyclone Sidr ( 2007 ) and Aila ( 2009 ) , mean income has dropped about 44 % and debt addition 40 % in the affected families. Majority ( 95 % ) of the husbandmans reported a loss of about 23 % income during 2008-2009 with regard to 2005-2006. Because of the lessening of agricultural income, many ( 72 % ) of the husbandmans have adopted extra business like twenty-four hours labour, rickshaw/van drawing etc. Still about 86 % of the husbandmans mentioned that they are gaining at least 10 % less now-a-days overall of that they used to gain from merely making agribusiness. About 89 % of the respondents reported house-hold plus loss worth on mean BDT 14600±5400 ( N=188 ) due to the frequent catastrophes. About 88,000 people have been reported as forced to migrate from the part due to unemployment, failed agribusiness, loss of capital and family assets and scarceness of nutrient and imbibing H2O. However, it was found that the linkage between clime alteration catastrophes and poorness is by no agencies linear and depends on legion factors associating to assorted environmental exposures and socio-economical factors of the part in inquiry. Better apprehension of the capable affair requires farther in-depth research equipped with extended multidimensional poorness database and part specific environmental function. 3rd International Conference on Bangladesh Environment ( BAPA-BEN ) 2
Although subjected to mass literature in the recent times, clime alteration does non yet feature conspicuously within the development docket of Bangladesh. However universe ‘s prima organisations like Intergovernmental Panel for Climate Change ( IPCC ) and United Nation Development Programme ( UNDP ) confirm that some of the most inauspicious effects of clime alteration will be in Bangladesh, where populations are most vulnerable and least likely to easy accommodate to climate alteration. For case, it is good known that clime will hold an impact on frequent catastrophes like cyclones, drouths and inundations ( e.g. , Walsh and Ryan, 2000 ) , agricultural productiveness ( Reilly et al. , 1996 ) and that clime affects both the net gross per hectare and the land value of farms ( Mendelsohn et al. , 1994, 1996, 2001 ) . It has besides been shown that clime affects the per centum of land used for harvests ( Mendelsohn et al. , 1996 ) . If climate conditions are non favorable, agricultural productiveness will be low. Further, farm income is still the king of beasts portion of family income in Bangladesh, increasing from 47 % in 1987-88 to 49 % in 1999-2000 ( Hossain, 2003 ) . It is hence rather possible that rural poorness will be linked with inauspicious clime conditions.
Despite of Bangladesh ‘s thriving successes in many development sectors, more than 50 million of our people still live below the poorness line. Many of these people live in remote or ecologically delicate parts of the state, such as river islands and cyclone-prone coastal belts, which are particularly vulnerable to natural catastrophes ( MoEF, 2008 ) . Besides this, agricultural income still constitutes a king of beasts portion of the rural income in the state. Climate alteration undermines the hard-earned development additions of the last several decennaries and besides threatens the sustainability of Bangladesh ‘s accomplishment in footings of development. The state has a history of utmost climatic events claiming 1000000s of lives and destructing past development additions.
Given these physical alterations including sea degree rise which would be straight affected the 1 million people by 2050, the support impacts may be felt in several ways, non needfully in any given sequence although the concluding result is ever a decline in employment or employability, income and ingestion. The impacts are felt in different grades by different socio-economic groups. These mean a poorer Bangladesh compared to a state of affairs without clime alteration and lower degree of development. Climate alteration impacts on support and therefore go a challenge of development under adversarial kineticss of nature. 3rd International Conference on Bangladesh Environment ( BAPA-BEN ) 3
Climate alteration impacts: Linkage between catastrophes and poorness
Climate alteration is clearly relevant to precedence development aims such as battling poorness, nutrient security, entree to basic services such as clean H2O, healthful life conditions and energy, and instruction. Scientists frequently suggest a close relationship with clime alteration and catastrophes, and in the recent times Bangladesh is confronting multiplex catastrophes. Broadly talking, the catastrophe literature suggests that exposure stems from location and societal disadvantages frequently manifest in income poorness ( Cutter, 1996 ) . Yet, bookmans are clear that exposure is based on economic, societal and physical factors. Locally, economic considerations include assets, type of employment, future income potency ; societal facets determining exposure include type of political establishments, marginalisation, minority position, instruction, gender, and age. Finally, physical exposure considers the geographics of supports and jeopardies, old catastrophes, resource depletion and scarceness, and established substructure ( Wisner, 2004 ) .
In Bangladesh Frequencies of terrible catastrophes like inundations, cyclones, drouths, riverbank eroding etc are have increased in the recent yesteryear with increased figure of sick persons and greater economic loss. One cause of this greater economic loss in the last decennary or so might be linked to the increasing costs of substructures and the necessities of day-to-day life. This, nevertheless, in bend is further beggaring the marginalized people who normally lose the most in any sort of catastrophe.
Approximately 42 % of the people live below poorness, and 85 % unrecorded in rural countries ( WDI, 2001, 2002 ) . Bangladesh ‘s income per capita has been systematically one of the lowest in the universe, and about half of it has come from agribusiness. Population force per unit area played a function in doing land scarceness. Arable land per capita declined from the little degree of 0.1 Hectares in 1979, to 0.07 in 1997 ( WDR, 1999 ) . About half of Bangladesh is located a few metres above sea degree, and about a 3rd is flooded in the rainy season. The state has been hit frequently by natural catastrophes. In 1976-2001, drouths affected 25 million people, inundations affected 270 1000000s of people, and rain and air current storms affected 41 million people ( EM-DAT database, 2009 ) . There is no comprehensive dataset on how many people have been unemployed or lost their income or physical assets due to those catastrophes. But it can be assumed that these catastrophes might hold linkage with the mentioned indexs of poorness.
Recent surveies have postulated that clime alteration will take to more poorness. However, the linkages postulated between the two have non been explicitly demonstrated but have instead been derived from =common sense ‘ . In this paper, the connexion between clime alteration and poorness is investigated utilizing income variableness, plus loss and migration via two mechanisms, inundations and failure of agricultural production due o drouths and microclimatic variableness. In both 3rd International Conference on Bangladesh Environment ( BAPA-BEN ) 4
instances, a connexion can be traced and the linkages are made explicit. For simpleness, the instance of two south-western coastal territories, viz. Khulna and Satkhira have been presented in the paper.
The survey was carried out in the three upazilas under two south western coastal territories of Bangladesh viz. Koyra ( 22o12′-22o31’N and 89o14′-89o26 ‘S ) and Paikgachha ( 22o31’22o42 ‘ and 89o17’-89o27 ‘ ) in Khulna territory and Shyamnagar ( 21o40’-22024 ‘ and 89o04’-89o16 ‘ ) in Shatkhira territory. Among the three upazilas Koyra and Shyamnagar is exposed seashore and Paikgachha is interior seashore in footings of tidal influence, salt invasion and cyclone and storm rushs. All of these three upazilas are located in the less economically developed portion of the state which has a rough environment with low rainfall, moderate drouth, hapless dirts and limited irrigation. Entire countries of Paikgachha, Koyra and Shyamnagar are 411, 1775 and 1968 sq.km with the entire population of 2.46, 1.92 and 3.16 hundred thousand severally ( ICZM, 2005 ) . Here mentioned that in Koyra upazila around 2000 peoples of =Munda ‘ an adivasi ( autochthonal ) community are subsist. The survey country is next to the Sundarbans mangrove forest and most of the peoples are to the full or partly reliant on forest merchandises for their support. Approximately 70 % Peopless in these countries live under poorness line and vulnerable due to both natural every bit good as socio-economic grounds.
Data aggregation and analysis
To carry on this survey, informations aggregation methods were included assemblage of secondary informations, family study and focal point group meetings in the survey country. A sum of 188 families were surveyed through a semi-structured questionnaire concentrating on their perceptual experiences on natural climatic events i.e. , inundation, drouth cyclone and its impact on their income variableness, plus loss and migration. Most of the inquiry asked to the respondents in a qualitative signifier. At the beginning of the informations treating all the informations were converted to quantitative signifier and analyzed by agencies of statistics to build the profile of rural poorness due to natural catastrophe. 3rd International Conference on Bangladesh Environment ( BAPA-BEN ) 5
RESULT AND DISCUSSION
Extensive inundations peculiarly affect the poorest-of-the-poor difficult as they lose whatever assets they have and besides suffer from deficiency of work and rewards. Floods besides contribute to the concentration of landownership due to straiten sale by the hapless in the post-flood state of affairs to the richer people in the community. Therefore increasing inundations due to climate alteration are likely to increase the incidence of poorness every bit good as menace the alleged & A ; lsquo ; in-between hapless ‘ or working category merely above the poorness line going & A ; lsquo ; ultra-poor ‘ .

The frequence analysis showed in the upper graph depicts that flood frequence is incresing over the recent decennary ( the black line represents 3rd order multinomial tantrum ) .
There is a broad concern that the inundation of 2004, 2007 and 2009 in the south-western portion of Bangladesh might be linked to the increasing catastrophes due to climate alteration. Satellite coverage of the inundations of 2004, 2007 and 2009 confirm that approximately 50 % , 30 % , and 60 % of the land country in Khulna and Satkhira were under H2O severally. At least 15 million people were affected during 2004 inundation while more or less 10 million people were affected during the 2009 inundation in Khulna and Satkhira part. 3rd International Conference on Bangladesh Environment ( BAPA-BEN ) 6

More than 60 % of the families in the part are somehow dependant of agribusiness for their supports while more than 45 % are highly poverty stricken ( ICZMP, 2005 ) . From the study in the survey country, it was found that, due to the recent inundation caused by cyclone Aila ( 2009 ) mean income has dropped about 44 % in the affected families. Most of this income dropped due to devastation of harvests and farther possibilities of agribusiness for the remainder of the twelvemonth and due to agricultural failure at least 40,000 people have for good migrated ( Table 1 ) . It is feared that, this might raise farther unemployment in the urban countries adjacent to this part. In Paikgacha and Koyra part, 30,000 people are still populating in stopgap houses over the elevated topographic points as they are unable to retrace their families due to chiefly miss of hard currency.
Micro recognition concern is acquiring popular here as people do n’t hold hard currency in manus and micro recognition helps them to at least by whatever they needs. Many of the respondents surveyed informed that they are traveling to alter or already changed their traditional profession because they can non last. It has been observed that people in the Paikgacha, Koyra and Shaymanagar part have adopted two or more primary business in the recent times ( 2007-2009 ) than that of one chief business during 2000-2001. The ground behind this generation is that, frequent implosion therapy and drouth are endangering one or two peculiar business at a clip, while holding multiple businesss people can still get by with the state of affairs though becomes poorer in the procedure. 3rd International Conference on Bangladesh Environment ( BAPA-BEN ) 7
