The goal of this study is to examine the effects of Rohingya Influx specially on vegetation land cover and LST in Teknaf Peninsula, Cox’s Bazar, Bangladesh over time. For doing so, the research followed three steps. Firstly, the primary and secondary data were collected from prescribed sources like LANDSAT 8 images from Earth Explorer (USGS) and the Shapefiles were collected from secondary sources. Then, Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST) functions are explored in geospatial environment to assess the effect of deforestation on the region. Finally, A correlation is shown between LST and NDVI for making a decision from the environmental perspective. The findings state that, the region around the Rohingya Camps progressively lost its vegetation density as a result of increasing deforestation. According to this analysis, there was 87.87 % vegetation cover in 2013, which gradually decreased before the Rohingya Invasion in 2017. After the incident in 2018, vegetation cover drops to 75.67 %. Similarly, area with no vegetation increased more rapidly than others. The outcome showed that the transition in land cover was quicker and more noticeable in recent time. As a result, the LST has been increasing over the years. According to the study, there were around 8.71 % of areas with high temperatures in 2013, which increased to 36.86 % in 2020. It indicates that a large quantity of vegetation has been lost as a result of deforestation, and the LST of this region has changed dramatically. Furthermore, data was examined by Union to assess the individual effect from 5 Rohingya camps, and it was discovered that the situation in Teknaf Union is terrible, while the situation in Baharchhara Union is comparably better. Finally, the results of the research encourage an extensive regional environmental policy to eradicate this problem. To recompense the loss of nature govt. and responsible department should take necessary steps like hill conservation or tree plantation.

COVID-19 undoubtedly remains one among the most significant disruptive occurrences of the 21st century, initially recorded in China and spread swiftly throughout the globe. Countries used varied measures to prevent it, from just advising them to levy complete lockdown. This article seeks to examine, through an analytical study done online in between 3 May to 4 July 2021, the influence of the pandemic on travel in Dhaka City, Bangladesh. Questionnaires were utilized to provide views on traveling number and mode choices for different "before" or "during" COVID‐19 travel reasons by respondents from different socio-economic backgrounds. The results were utilized in the analysis of (i) travel frequency and (ii) the preferences of mode using Mann Whitney, Kruskal Wallis with Wilcoxon Test. Analyses show that COVID‐19 produced a wide variance in mode choices with travel frequency, Males continue to go to work and shopping and risk them more than women. Despite being a public transport, busses continue to be most preferred during Covid situation. In addition, most individuals continue to use busses at the cost of health because of the absence of cheaper alternatives. The government should have to maintain adequate sanitary procedures in public transport and the ICTs and foot and bicycle facilities must be upgraded to prevent the consequences.

Environmental degradation and its impacts for islands and coastal nations have prompted policymakers and academics to focus on resettlement of individuals residing within those risky areas. Similar initiatives have been introduced in Bangladesh in 1972 named "Cluster Village Project", and individuals who are landless or have been displaced as a result of river coastal erosion, storms, or flooding have been relocated as part of the scheme. Due to economic and political complexity of the subject, several ruling parties gave it different titles, although none of them changed dramatically from the basic targets and strategies of resettled populations and the welfare of the landless and harsh weather victims. This research focuses on how and to the what degree moved households' livelihoods have altered, including the opportunities and restrictions of relocated settlements. According to an empirical study conducted in four Guchchhograms of Narail District's Lohagara Upazila, the migrated people's livelihood conditions have improved significantly, but location specific drawbacks and link to productive resources, the local labor market, and a number of the project's specific goals have not been met. Rehabilitated households face some of the same hazards as before; however, adequate agricultural lands and good distribution can help to mitigate such risks.
