With the increasing tension on the global sustainable environment in the urban areas, it is essential to monitor the airborne pollutants and understand the underlying factors that can trigger the situation in a worst-case scenario. Because of its cramped living conditions, excessive coal and fuel usage, and rapid deforestation, the southeast Asian region has historically had worse air quality than the rest of the world. The economic hubs of India and Bangladesh, in particular, have drawn so much attention away from rural regions that unrestrained urbanization is becoming controversial for planners, engineers, and stakeholders in sustainable development. This research combines the two main Asian capital regions, Delhi and Dhaka. It analyzes the change in nitrogen dioxide (NO2) concentration, land surface temperature (LST), and vegetation dynamics across three years (2019–2021) for summer and winter. The NO2 concentration data from Sentinel-5P has been extracted using Google Earth Engine (GEE), and Landsat-8 imagery was utilized for LST, Normalizer Vegetation Index (NDVI), and Enhance Vegetation Index (EVI). The statistical analysis has been carried out by dividing the research regions into one sq. km grid (1512 grids for Delhi and 1485 grids for Dhaka). According to descriptive research, Dhaka's condition is worse than Delhi's, with significant vegetation loss with LST and NO2 concentrations rising. In both research regions, the NO2 concentration is high throughout the winter. The Pearson correlation value demonstrates a negative association between total NO2 concentration and mean NDVI and EVI values and a positive relationship between total NO2 concentration and mean LST. The data have been further assessed using linear regression, which overlaps the correlation result with a maximum R-squared value of 0.2998 for NO2 and EVI in winter 2019.

Bangladesh started its nuclear journey on 02 October 2013 with the inauguration of the first phase of Rooppur Nuclear Power Plant construction. The main purpose of the study is to find out the impacts of Rooppur Nuclear Power plant on the environment, social economy and socio-cultural elements at surrounding areas of the proposed site. Field observations, household surveys, FGD, key informant interviews, daily newspapers, google engine, journal articles, reports, and other relevant sources were used to collect the data. To fulfill the objective of the study, environmental impact value (EIV) tool was applied. After observing and calculating all the components, authors were found positive impact on socio-economic impact (+198) and negative impacts on environmental parameters (-65) and socio-cultural parameters (-130). Finally, the project's total score (+3) indicates the project has a moderately positive impact on the social economy and environment and suggests that the project is acceptable. The significant positive impacts of the Rooppur nuclear power plant will be industrial and infrastructural development, economic growth, employment creation, knowledge transfer, river excavation, tree plantation, no greenhouse gas emission if the project follows national and international laws and legislation, a proper environmental management plan, strong cyber security, and free from any corruption or illegal activities.

This study explores the modality and trip chaining patterns of individuals in Dhaka, Bangladesh. We use household-level trip data for a day collected from randomly selected respondents of the Dhaka Metropolitan Development Plan area. We found that walking and rickshaw are the dominant modes of travel. The majority of individuals are unimodal and mostly depend on either walking or on rickshaws. Individuals generally walk for the first and last-mile connections to public transit. Cars are used more for non-home-based business trips. Personalized modes such as cars, cycles, and motorcycles are present at a higher proportion in the super complex trip chain than other types of chains.
