Bangladesh is the most densely populated country with 1188 people per square kilometers. It has a total population of 160 million people and among which more than 16 million people lives in the capital, and that makes it one of the most densely populated cities in the world. Consequently there are huge needs for high rise housing to accommodate all those people or otherwise shift them to other place. But our country, at present, does not have enough resource to build up a newer city so that they can solve accommodation, infrastructure and unemployment problems. Thus, the only option is privatization of the housing which also has started in our country and this scenario is appearing to be more devastating. These buildings does not respect nor reflect our culture, history, society, religion, norms, behavior or community. Additionally, these housing units at final level of finishing are out of reach for the low and middle income people even though it was intended to be built for the low income group. Urban poor is a problem and an also an opportunity for this City. They are actively taking part in the economy and they are the server of the 4th class services of the society. But they don’t have proper place to live and facilities to lead their life style. Thus they sometimes choose different path of life leaving behind community values. However, they have lots of potential in the city and can easily make them useful to contribute to the culture and the society of the city. With a better place to live that will support their life style, they can easily become the keeper of their culture and crafts. With proper housing they can produce income and support their families. We can easily rely on their craftsmanship to retain our culture. Architecture should be sustainable and for all. So I have decided to work on the housing for mid and low income group so that they can stay and serve the city. It’s not only the design strategy but also the complete systematic process so that it can ensure that the end user can afford it. Our country is rich in culture, festivals, history and religion. So the design process should be sophisticated and ingenious to keep it in place. Also in our country still it’s a common scenario that most of the house wives doesn’t add to any income for the family. From my perspective a sustainable design can make that happen too. Thereafter my thesis intends to develop an architectural solution that can revive this city of Dhaka through ideas sustainable for the city and dweller as well as systemize the infrastructure to manipulate their passive income strategy and ensure a healthy communal and social life for them.

A computer model for use in predicting the impact of various improvement options on command area expansion of a deep tubewell irrigation system has been developed. A field study was conducted on 11 selected deep tubewells located at two sites, namely Dhamrai and Thakurgaon, in Bangladesh to collect necessary physical data to provide irrigation engineering insight and a basis for testing and application of the model. The results of the investigation revealed that the actual discharge of most of the deep tubewells was lower than the design or rated capacity. The duration of pump operation in the majority of the study deep tubewell areas was extremely low. The conveyance losses in all of the study systems were very high. Even though a portion of those losses was reused in the system, particularly in rice growing areas, they caused serious difficulty in delivering water to remote fields, thus, restricting the command area. The overall irrigation efficiencies in all of the wheat growing areas of Thakurgaon were low. Considerable losses and waste of water after it was diverted from the field channels due to lack of leveling and poor water control were mostly responsible for the low efficiencies . Excessive percolation losses due to inadequate puddling of the soils during land preparation and frequent drought conditions resulted from poor distribution of water in some of the rice growing areas of Dhamrai caused relatively low overall irrigation efficiencies. The overall efficiencies of the pumps both driven by diesel engine and electric motor were found to be much lower than the recommended values. The developed model was applied to predict the expected command area under both existing and modified physical conditions. The model predicted command areas were compared with the actual field observed values and necessary adjustments were discussed. The impact of each of the improvement alternatives considered in the study was determined by comparing the predicted command area under the modified conditions with that under the existing physical settings. An economic analysis was performed to determine the cost effectiveness of most of the alternatives. Application of the model in evaluating the farmers' pump operation practices was demonstrated. Use of the model to assist the farmers in planning the command area and delivery schedule was also indicated. Although the model was developed to use in a deep tubewell irrigation system, it can also be used in the system served by a low-lift pump or by a turnout in a large irrigation project.

The primary objective of this thesis is to differentiate between the risk factors for pre-and post-monsoon cholera epidemics in rural Bangladesh by analyzing the complex interaction between select environmental, cultural/behavioral, and socioeconomic variables over space and time. In rural Bangladesh, cholera epidemics correspond with the annual monsoon: the first, and smallest, occurs between March and June, while the larger cholera peak occurs between September and December. The differences between the spatial and temporal patterns of seasonal cholera are analyzed, and the risk factors are calculated for pre-and post-monsoon cholera epidemics. The theoretical approach that underlies this medical geographical study is disease ecology, which espouses that risk of disease is caused by an interaction between people and their environment. This thesis is structured around a holistic understanding that human-environment interactions are inseparable. In Bangladesh, the monsoon season typically starts between May and June. The 1992 and 1993 cholera peaks occurred just before the monsoon in April and March respectively, while the 1994 cholera peak occurred between April and June. In 1992 and 1993 cholera incidence increased in the post-monsoon period, and peaked in October. The 1994 post-monsoon cholera peak occurred in November. There is a regular temporal pattern to cholera, as the peaks followed a seasonal pattern with the smaller epidemic occurring in the pre-monsoon period and the larger epidemic occurring in the post-monsoon period. This study shows that there are different risks associated with pre-monsoon cholera epidemics and post-monsoon cholera epidemics. The two main risk factors associated with cholera incidence pre-monsoon were bari population (i.e., crowding) and a house located within the flood controlled area. These two variables were even more strongly associated with post-monsoon cholera incidence to a greater degree, along with a number of other variables including water use, sanitation practices, and socioeconomic status.

Tableau d'honneur de la Faculté des études supérieures et postdoctorales, 2011-2012 / Dans un contexte où les prix des aliments sur le marché international tendent à la hausse et, à court terme, sont soumis à des fluctuations importantes, il est fondamental de mettre en place des politiques visant à assurer une nutrition suffisante et adéquate des groupes les plus vulnérables. La plupart des études sur le sujet se concentrent sur les effets « monétaires » de la crise et, en même temps, elles font l'hypothèse que les membres de chaque ménage partagent équitablement les conséquences néfastes des chocs sur les prix. Je propose une approche alternative, basée sur un système de demande de type AIDS {Almost Ideal Demand System) au Bangladesh, visant à mesurer les conséquences de la crise alimentaire sur la santé nutritionnelle des individus. De plus, les données disponibles me permettent de prendre en compte la dimension de l'allocation intrafamiliale des ressources. Mon approche est ainsi centrée sur les besoins des individus, plutôt que sur les besoins agrégés des ménages.

Bangladesh's ready-made garment industry and its harsh working conditions have been the center of intense scrutiny for the past decade, especially following the massive death tolls of the Tazreen Fashions factory fire in 2012 and the Rana Plaza building collapse in 2013. While lauded by many for its tremendous contributions to the Bangladeshi economy and its employment of primarily women, the garment industry is responsible for causing harm both to the women who work there and the local environment. Women workers are physically and verbally abused in the workplace for little pay, while the factories emit pollutants that contaminate the drinking water in surrounding areas and destroy crops. The global North, while being the main destination for exports from Bangladesh, refuses to intervene in a meaningful way to help the people who supply cheap goods for them, even in spite of highly publicized agreements to help improve factory safety, like the Accord on Fire and Building Safety in Bangladesh. This paper will examine the Bangladeshi garment industry using an ecofeminist lens. Doing so helps to illustrate the various power relations involving gender, capitalism, and the environment that characterize the industry. These axes of power, all stemming from the same mindset of superiority, reinforce one another both ideologically and materially. Seeing how these different issues – including harassment, pollution, crop loss, and forced displacement – are connected will help to determine how to best solve each of these individual issues.

Thesis advisor: Marilyn Cochran-Smith / Changes in climate are being experienced by people globally, and increasingly pushing into school science. Educators struggle to make sense of the critical thinking and agency youth will need to face such changes. To this end climate change curriculum, teaching and learning in schools has garnered significant attention in educational research in the last decade. This is particularly important given that formal education is viewed as an important canvas for building the capacity of young people. However, curriculum materials are mostly understudied and taken for granted. In addition, there is also a paucity of scholarship from the global South with respect to climate change education. To address the need for climate change education as well as inclusion of international perspectives, this dissertation presents an analysis of climate change content in select textbooks and supplementary educational materials from Bangladesh, California & Ghana, and three widely different jurisdictions. Using a cultural politics framework, I explored the following questions related to climate change content in textbooks and supplementary materials: (1) How is climate change portrayed in select official/state approved textbooks (2) How is climate change portrayed in supplementary materials? (3) What are the similarities and differences the textbooks and supplementary materials? Using a classical content analysis approach, I show that the content in all three textbooks acknowledged the contributions of human activity to climate change, for example discussing the primary role of human activity to the warming of the planet. However, there were some distinct differences when it came to discussions around the scientific consensus on climate change. While Bangladesh fully noted the scientific consensus, California presented mixed messaging and Ghana did not reference the scientific consensus at all. The textbooks from the three jurisdictions included local and global climate change impacts and policy solutions. My analysis also showed that the two supplementary materials from the United States used different frames to challenge each other’s messaging. And while Heartland Institute cast doubt on the scientific consensus, the Paleontological Research Institution embraced it. Lastly, the United Nations, as an exemplar of content intended for an international audience, was constructed similar to the textbooks in attempting to balance local and global perspectives on climate policy solutions. Importantly, I argue that textbooks and supplementary materials need to provide robust content that attends to the context-specific complexity of climate change. I discuss cultural influences on climate change education. Finally, I conclude with recommendations for the inclusion of more localized ideas on climate change impact and policies / Thesis (PhD) — Boston College, 2022. / Submitted to: Boston College.
