Thesis: Exploring the Role of Climate Change Adaptation Practices in People’s (Non)-Migration Decision: A Case from Coastal Area of Bangladesh
Abstract: Despite confronting severe climatic risks, many people prefer to remain in climate hazard-prone areas rather than migrate. Environmental non-migration behavior, however, has gained relatively little research attention in the field of migration processes. This study aims to unveil the determinants motivating voluntary environmental non-migration decisions in coastal Bangladesh, an area highly exposed to flooding, coastal erosion, salinity and cyclone. Applying a Probability Proportional to Size (PPS) method follows cluster sampling, we selected 400 household respondents for a questionnaire survey from Buri Goalini Union of Satkhira. Applying a mixed method (i.e., both quantitative and qualitative) approach, major empirical results of this study suggest that even though all respondents lived in a similar situation in terms of climatic hazard and exposure, 60.5% of the respondents reported themselves as voluntary non-migrants. Furthermore, these non-migrants enjoyed higher socioeconomic and socio psychological advantages and availed more local support from different government and non-government organizations than involuntary non-migrants. Again, adaptation to agriculture, fisheries, lives tock, and alternative livelihood appeared to build their higher degree of aspiration compared to involuntary non-migrants. All these features lead to a favorable environment that ultimately drove the respondents to become voluntary non-migrants.

Thesis: Chemical modification of biochar’s functional groups enhances phosphate and arsenite adsorption
Abstract: Anionic arsenic (As) species and phosphate often show similar behavior in soils. Bioavailability of these anionic species has a significant implication for crop production and soil health. Biochar (BC) is considered an effective amendment for managing these anionic species. This study aims to evaluate how surface-modified biochars influence phosphate and arsenite adsorption. Biochars with a range of functionalities were produced using mineral doping, and chemical oxidation with hydrogen peroxide. These biochars were then characterized using different chemical techniques, including FTIR. Next, a phosphorus adsorption study was conducted with fresh, mineral-doped and chemically oxidized biochars. A desorption study was also conducted to understand the strength of sorption. Moreover, an adsorption study was carried out using three different biochars fresh, oxidized, and doped in interaction with As. Our results showed that chemical oxidation increased oxygen-containing functional groups while mineral impregnation decreased their presence, resulting in a reduction in cation exchange capacity. As a result, phosphate adsorption was significantly higher with mineral- doped biochar (2.5 mg g-1 biochar) than in fresh biochar (2.2 mg g-1 biochar) treatment. The strength of binding was higher for positively charged biochars. Similar to phosphate, the As adsorption was also higher in the doped biochar (~0.50 mg g-1 biochar) than oxidized biochar (0.20 mg g-1biochar). Surprisingly, the As adsorption was higher in the oxidized BC than fresh BC possibly due to its co-adsorption with cations. Altogether, our results suggest that biochar with positive surfaces could strongly bind negatively charged ions from aqueous solutions and soils.
