Dhaka is a densely populated city in the world. There is no room for the newcomer. If climate refugees also came here, it would be intolerable. They may cause more pollution of Dhaka. They use the open toilet and open fire. They throw garbage into rivers. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get Original EssayA huge migration of these refugees to Dhaka city is now a regular phenomenon. But this kind of displacement in Dhaka city is very alarming for urban dwellers as it increases pressure on the existing system and puts a strain on the government. Slum improvement not only improves the quality of life of the urban poor but also supports climate change adaptation measures. The planned migration of climate-induced displacement is a current concern. The design of the built environment, including infrastructure, sanitation, etc., will promote a healthy lifestyle, eliminating the effects of haphazard growth and the effects of environmental degradation. Decentralization of some slum settlements to nearby cities can be considered if located above the water body, such as natural lakes, ponds, etc. The poor living in slums contribute to the urban economy in many ways. To ensure their socioeconomic living standard, their income (daily or monthly) should be stable. According to survey data, most of them are daily wage laborers such as rickshaw pullers, brick breakers, etc. The heir's income is very susceptible to some natural or man-made events such as water logging in Dhaka city. According to interviewees, they often remain hungry until they earn something to eat. The suffering of these people, considering recent and future urban risks, must be integrated during policy preparation. The objectives of the study are: to identify why refugees come to Dhaka; what dangers they faced in their locality; assess the current situation of water, sanitation and hygiene in slum areas; To find out how much threat they pose to the city of Dhaka. Literature review on Bangladesh context Bangladesh has a long history of disaster management during and after a cyclone. These coping skills play a vital role in surviving in people's abilities. Rashid et al. (2006) conducted a study on the coping strategies of families affected by a disaster to sustain their livelihood. Three broad categories are classified: Strategies for adjusting the decrease in household food consumption and relocating household labor to develop current income Unsecured loans which refers to unsecured loans by providing household assets as collateral. Secured loans denotes loans against assets owned by the family. Here the current adjustment is most frequent among these three strategies followed by families. There is a lack of documentation of Indigenous knowledge and practices found in the literature review. An attempt was also made to review the way in which the government. and NGOs influence coping strategies. Mukherjee (2009) reflects on gender-specific seasonal vulnerabilities to show how problemsare aggravated for poor women in Bangladesh during the season of deficit. The study by del Niño et al. (2001) reveals households' coping strategies after the 1998 crisis, including borrowing, reducing spending and selling assets. Among them, the main family coping mechanism is borrowing in terms of both the value of resources. To cover consumption shortfalls, credit was sought from informal sources. Basic human needs and vulnerabilities Books and Anger (2005) point out that the concept of adaptive capacity makes sense in the context of which resources and systems would be affected by climate change. The U.S. Agency for International Development's Famine Early Warning Systems project (FEWS 1999) focused its vulnerability assessment guidance on food security. Books et al. (2005) list 46 proxy variables; researchers specifically include geography, governance, demography and technology. They looked for correlations between these vulnerability proxies and historical ten-year fatalities and derived from these results 11 key indicators of vulnerability: a population with access to sanitation, literacy rate (15-24 years), voice and life expectancy at birth. Unlike Azar et al. (2005), this set of indicators explicitly considers some aspects of reproductive health and gender equity. These indicator compilation efforts do not specify in their lists or models the interactions and feedbacks between vulnerability factors. Conceptual and analytical framework To understand why a hazard becomes a disaster and for whom, the concept of vulnerability is crucial. Using the concept of vulnerability as a characteristic of risk exposure has allowed researchers to sidestep the issue of what causes vulnerability (Canon 2001). In the social sciences, the human dimension of vulnerability has received significant attention. A person's vulnerability can be identified by the interaction of natural events and economic, political and social factors. Canon (2001) points out that most uses of the idea of ​​vulnerability accept that it is part of a continuum or classification of people. This vulnerability is at the negative end of that scale. Adger (1999) argues that vulnerability should be viewed as the exposure of a group or individual to stress due to environmental and social change. This definition contrasts with the dominant view of disaster vulnerability. Climate Change Scenario in Bangladesh and Development Issues According to the IPCC in the recently released fourth assessment, the following changes in climate trends, variability and extreme events were observed:In Bangladesh, the average temperature has been trending upwards by approximately 1°C in May and 0.5°C in November during the 14-year period from 1985 to 1998. Average annual precipitation shows increasing trends in Bangladesh. Decadal precipitation anomalies have been above long-term averages since the 1960s. Severe and recurring floods occurred in 2002, 2003 and 2004. It has been noted that cyclones from the Bay of Bengal have decreased since 1970, but the intensity has increased. The frequency of monsoon depressions and cyclone formation in the Bay of Bengal has increased. Water scarcity has been attributed to rapid urbanization and industrialization, population growth and inefficient use of water, which are exacerbated by climate change and its negative impacts on water demand, supply and quality. Salt water from the Bay of Bengal is said to have penetrated 100 km or more inland along tributary canals during the dry season. The decline of.
