“…Similarly, in Khulna city, the built-up growth was 28% between 1997 and 2017 [37]. On the other hand, mid-tier district towns like Comilla experienced a net increase of 7.8% in built-up area in the last two decades [38] while it was nearly 25% in Mymenshigh [39] and ~ 69% in Barisal [40].…”

Sustainable urban development is a key compoment in the United Nation’s Sustainable Development Goals. Monitoring urbanization is critical for planners, governments and non-governmental organizations, and scientists to design policies that maximize the use of natural resources and accommodate development while reducing environmental effects. This research aims to analyze how urbanization patterns have changed in the largely unknown least developed regions of Bangladesh. Multispectral satellite imageries over 30 years (1991 to 2021) were used to analyze the urbanization pattern of Jamapur district. Utilizing object-based image classification and on-field validation for seven Land Use and Land Cover classes, it was found that built-up area expanded by 748.92% during the past three decades while depleting bare soil (− 97.65%), deep waterbody (− 79.33%), shallow waterbody (− 8.46%), light vegetation (− 14.28%) and agricultural land (− 26.33%).. Because of increased in built-ups, the land surface temperatures (LST) were also increased over the study period (the minimun recorded LST were 12.84 °C, 15.89 °C, 15.8 °C and 17 °C while the maximun LST were 17.93 °C, 23.7 °C, 23.79 °C and 26.73 °C for the year of 1991, 2001, 2013 and 2021 respectively). This study will act as a baseline for future studies It be insightful to urban planners and policymakers in developing countries regarding urban sustainability and minimizing urban risks and hazards in the least developed districts.

“…Warrick et al [4], Karmakar & Shrestha [5] and Debsarma [6] provided assessment of changes in temperature and rainfall over Bangladesh, while Chowdhury & Debsarma [7] and Mia [8] reported changes in temperature based on analysis of historical data of some selected weather stations in Bangladesh, Karmakar & Nessa [9] and Karmakar [10] provided "assessment of the effects of climate change on natural disasters". "The rainfall and temperatures (Singh et al 2013) are the most important fundamental physical parameter among the climate as these parameter determine the environmental condition of the particular region which affects the agricultural productivity" [11][12][13].…”

In this study, based on the analysis of historical data on temperature and rainfall recorded at 34 meteorological stations, It is reveal Climate change and variability in Bangladesh from 1989-2019. Analysis of rainfall data showed that for most stations, the total rainfall showed an increasing trend for the monsoon and post-monsoon seasons. The average increase in monthly average maximum and minimum temperatures during the 31 years from 1989 to 2019 is quite significant. These changes will threaten Bangladesh's significant achievements over the last 31 years in increasing incomes and reducing poverty. Analysis of rainfall data showed a rising rainfall trend for most stations during the monsoon and post-monsoon seasons. Analysis of rainfall data showed that rain increased during and after the monsoon but decreased during the winter. Assessment of changes in maximum temperature, minimum temperature, and rainfall patterns. Bangladesh's annual maximum temperature was increasing on average by 34 stations. The greatest change in month-average maximum temperature was found in the Southeastern region of Bangladesh for maximum months.

Anthropogenic activities over the last decade in Occidental Mindoro have shaped habitat loss and wildlife endangerment. In the 20th century, farming by the local community was perceived to be the leading threat to the decline of native flora and fauna. Hence, this study investigated the impacts of anthropogenic practices in Occidental Mindoro in three time series (2019, 2010, and 2004) using Geographic Information System (GIS) and Remote Sensing Techniques by assessing the following geomatic matrices: (i) the Land Use and Land Cover Change (LULCC), (ii) Normalized Difference Built-up Index (NDBI), (iii) Normalized Difference Vegetation Index (NDVI), and (iv) Land Surface Temperature (LST). The results of the study showed the following: (i) An increase in LST and NDBI and a decline in NDVI from 2004 to 2019; (ii) An increase in LST is correlated with an increase in NDBI and a decrease in NDVI values; and the (iii) LULC maps affirmed the decline in forest cover and an increase in cropland, grassland, and barren land. These quantitative measures of landscape heterogeneities may imply that anthropogenic activities over the span of ca. 20 years have already affected the forest cover in Occidental Mindoro. This study recommends implementing more land and conservation management strategies and policies by essential stakeholders such as the Government and Non-government organizations.
