Vulnerability Assessment of Women and Children due to the Jamuna Riverbank Erosion: A Study of Kastapara Village of Bhuapur Upazila, Tangail ., AFROZA Bangladesh faces frequent natural disaster, including cyclone, storms, droughts, thunderstorms, earthquakes, landslides, floods and riverbank erosion, which occur almost annually. Among these, riverbank erosion stands out as one of the most frequent and destructive phenomena, often linked to flood occurrences. This disaster causes significant destruction, displacing people from their homes, destroying infrastructure, agricultural land, crops and essential belongings. Bangladesh predominantly a patriarchal society, where men typically act as the primary earners and head of households. In this patrichal structure, crucial decisions regarding a family’s and women’s life such as education, participation in economic activities, marriage and family planning are usually made by male family members. Women’s role are often limited to biological reproduction, caregiving and managing household chores. Women are also continue to lag behind due to lack of security. Incidents of violence and harassment against women as well as children have become alarmingly frequent in Bangladesh. Because of these harassment women and children faces difficulties due to any disaster as well as riverbank erosion. This study examines the erosion induced vulnerabilities of women and children in kastapara village, under Bhuapur upazila, Tangail district. The study also attempts to find out their survival and copping strategies during and after riverbank erosion. In this study, primary data collected through questionnaire survey has been used to determine the vulnerability. Sample size has been calculated using Cochran’s modified formula for known population. All respondents are women. A total of 230 questionnaire survey has been conducted using purposive sampling techniques. Collected data systematically arranged and entered into Microsoft Excel spreadsheet (Excel 13), which served as the foundation for subsequent analyses. To further process and summarize the data, statistical analysis software SPSS (16.0) was utilized. Microsoft Word (2013) was used for documenting findings and creating written reports. Furthermore, GIS software (10.1) was used to prepare maps. Secondary information was sourced from a wide range of published and unpublished materials, including documents from government and non-government organizations such as BWBD, LGED and CEGIS. Additional vii resources include local government offices, Dhaka University’s libraries and online materials like reports, articles, books and news outlets have also been used. An indicator-based approach has been employed for vulnerability assessment, utilizing the Riverbank Erosion Vulnerability index (REVI) to evaluate the vulnerability of women and children in the study area. The formulation of REVI incorporates multiple variables grouped under eight parameters and three dimensions. The study reveals that most villagers face annual floods and riverbank erosion. The results indicates that, while the overall vulnerability of women and children in this region is relatively low, individual index value for exposure, sensitivity and adaptive capacity suggest high to moderate vulnerability. Women, in particular, faces different types of difficulties. Furthermore, those who seek shelter in temporary accommodations often experience physical and psychological violence and distress. Women have little to no understanding of challenges associated with erosion, and their vulnerability is intensified by insufficient support from the government and other organizations. No prior studies in this area have assessed women’s and children’s vulnerability using an index-based formula. Therefore, I focused on analyzing the vulnerabilities of both women and children in this region. This study focuses on identifying the vulnerabilities of women and children to aid researchers and planners in creating targeted initiatives and policies, ultimately aiming to enhance their lives and promote a supportive and inclusive environment. This thesis is submitted for the degree of Master of Philosophy.

STUDIES ON THE ZOOGEOGRAPHICAL CONFIGURATIONS OF THE INLAND FISH HABITATS IN BANGLADESH Mohiuddin Sarker, Muhammad Conservation of the inland fin fish in Bangladesh has been compromised due to a lack of zoogeographic division and ecofaunal relationship identification. The study attempted to identify finfish fauna, establish ecofaunal relationships, estimate zoogeographic division, and assess the water quality at 13 stations in Bangladesh's 8 major water bodies, i.e., the Brahmaputra and Jamuna River from the Brahmaputra Jamuna River Basin, the Ganges River and Padma River from the Ganges-Padma River Basin, the Hakaluki Haor and Meghna River from the Surma-Meghna River Basin, and the Kaptai Lake and Sangu River from the Basin of Chittagong Region from June 2018 to February 2022. Systematic Index of Freshwater Finfish (SIFF), Grounded Theory or Narrative Analysis, Mapping and Satellite image analyses, Multivariant statistical techniques like Jaccard's dichotomy coefficient, cluster analysis, Non-metric Multidimensional Scaling (nMDS), Principal Component Analysis (PCA), and Water Quality Index (WQI) were used in this investigation. Permutation tests have been conducted to justify the statistical validation and p-value estimation. A total of 193 finfish species belonging to 19 orders, 50 families, and 121 genera were identified from the study areas. These species represent 6 critically endangered, 16 endangered, and 21 vulnerable finfish species. The Brahmaputra River, Jamuna River, Ganges River, Padma River, Hakaluki Haor, Meghna River, Kaptai Lake, and Sangu River represented the alluvial riverine, braided riverine, meandering riverine, dynamic riverine, marsh wetland, estuarine, lacustrine, and mountain stream ecosystems, respectively—distinct fish fauna and characteristics of these eight ecosystems established ecofaunal relationships. The Brahmaputra-Jamuna River Basin, Ganges-Padma River Basin, Surma-Meghna River Basin, and the Basin of Chittagong Region were identified as inland fish zoogeographic zones in Bangladesh. This zonation was based on river and drainage system divisions, finfish faunal dispersion, ecosystem diversity, and distributional dissimilarities of finfish families, genera, species, and endemic species. Significant seasonal fluctuations in water quality have been observed across all study areas. The water quality of eight inland fish habitats was assessed using seven indices, with EC, TDS, alkalinity, and temperature being the principal ones. Policymakers should adopt a conservation plan based on zoogeographic zones. Priority should be given to improving the principal components of water quality and protecting threatened finfish species that inhabit single habitats. This thesis is submitted for the degree of Doctor of Philosophy.

Advocacy or Development? An Inquiry into the Activities of Environmental NGO’s in Bangladesh Raufe, Md. Abdur The present study was undertaken to find out the role of environmental NGOs on advocacy or development in different areas of Bangladesh. A total of 61 environmental NGOs were selected from four different geographical regions like north bengal, south-west part, coastal areas and central Dhaka. Field survey was conductcd to establish the study and surveyed on NGOs key personnel and different professionals. From the result, it was found that from 61 NGOs, most of them initially establish as development organization but 55 NGOs changed their views and now working as environment sectors. From the result, it was found that out of 61 NGOs, 36 NGOs collect fund from internal sources and 25 are collect fund from external sources and 40 NGOs are involved to spend money as bribe for funding. For advocacy, the NGOs are involved on environment and development of people like climate change, water contamination, social corruption, women torturing, early marriage and population increasing. NGOs are using media, seminar, rally, poster display to support the advocacy. The NGOs fire also doing the awareness of the people on various environmental acts by the ministry of environment and forest, GoB. 56 NGOs deals with health, fisheries and population, 49 deals with plantation and sanitation. However, 53 NGOs are working on both environment and development, only 4 NGOs are working for environment and 4 are working for only development. After advocacy it was also revealed from the study that out of 61 NGOs, 38 and 49 organizations have the good relations with government and donor agency respectively. From the study it could conclude that all the NGOs of different regions of Bangladesh are involved on both development and advocacy but they are working on mostly development rather than advocacy which is key issue in developing country like Bangladesh This thesis is submitted for the degree of Master of Philosophy.
