“…Looking at the matter from a different angle, it has been observed that in other regions of the country, the surface temperature of the Hakaluki Haor rose by 5. 21 [33,28,18] . Therefore, the increase in temperature is a matter of concern for the wetland ecology.…”

Wetlands in Bangladesh have undergone rapid degradation, primarily attributable to a range of factors. These factors include a marked increase in population, extensive water diversion for irrigation purposes, depletion of swamp forests, as well as other natural and anthropogenic causes. Hakaluki Haor is a vast wetland area located at North East in Bangladesh provides habitat for a diverse range of fish species. Due to natural and anthropogenic causes, fish species are declining in the Hakaluki Hoar. Fish species are declining primarily due to the utilization of harmful gear, the drying of beels every year, and overexploitation. The aim of the research was to assess the occurrence of various fish species in different seasons, their distribution, and conservation status. The research was carried out over the course of three seasons (summer, autumn, and winter) spanning from September 2017 to August 2018. The study utilized a mixed methodology approach to investigate the fish assemblage, which included examining the fish catch on boats along with the fish available in the nearest assembling center (fish market). In addition, the Shannon-Weaver index was followed to recognize the species diversity (H), richness (D), and Evenness (e). The research documented the presence of 64 fish species that were classified into 25 different genera, and 24 families across 10 orders. The order Cypriniformes was the most prevalent, constituting 42% of the total number of species identified. Other orders such as Siluriformes (22%), Perciformes (16%), Channiformes (6%), and Clupeiformes (5%) also demonstrated a considerable variety of fish species, although Cypriniformes had the highest dominance with 42% of the total species documented. Additionally, the research determined that among the complete assemblage of fish species identified, a total of 14 (18.88%) were classified as species facing threats. Based on the analysis, 6.25% are vulnerable, 12.5% endangered, and 3.12% are critically endangered as per IUCN Redlist. The research observed the Shannon-Weaver diversity (H), richness (D), and evenness (e) values for the fish species, which were found to be 2.47, 6.28, and 0.65, respectively. Moreover, participants retorted that the present income from fishing had decreased as compared to five years ago. The research finds that anthropogenic pressure is one of the key reasons to fish decline at Hakaluki Haor. According to the findings of the current research, community-based wetland conservation and management have been proposed as a viable and sustainable strategy for augmenting the fish species abundance.

“…The natural processes involve the slope, topography, relief, geological condition, materials, geospatial location, weather conditions, land use and land cover settings as well. Prior to the post-industrial revolution, developed and developing nations in a race to attain a peak in their industrialization, economic growth and wealth development are producing excessive amount of greenhouse gases, especially carbon dioxide (CO 2 ) (CPD, 2019;Ganguli, Islam and Garai, 2018;Islam et al, 2021;Mohiuddin et al, 2021). In order to accelerate economic development, most countries are fully concentrated on infrastructural development and pay little or no attention on its impact on the natural environment, ecology and ecosystem.…”

This study was aimed at assessing the spatiotemporal variation and trends of LSTs and vegetation dynamics impacts on landslide vulnerability within CHTs region. The variation trends of land surface temperatures (LSTs) and normalized difference vegetation index (NDVI) between 2001 and 2022 were assessed using time series datasets from the moderate resolution imaging spectroradiometer (MODIS). Relevant data on the multi-variant landslides, causalities and associated datasets were collected from different archival sources and random field investigations were performed for cross verification purpose. Results showed that the variation trends of LSTs between 2001 and 2022 were mostly in an increasing mode (94% grid cells) with a yearly average LST increase of 0.34°C. Contrarily, during the same period, the variation trends of vegetation index were in a decreasing mode, while total NDVI value on average slightly increased by 0.2. Thereafter, the variation trends of LST and NDVI were significantly correlated and most of the grid cells have shown converse correlation. The landslide prone areas are mostly in the above correlation locations. The study further revealed that a total of 469 severe landslide occurrences were recorded in CHT region with Rangamati district being the most affected area with 48.6% severe landslides occurrences. Therefore, this study establishes a strong influence of climate change effects on landslide vulnerability in the CHT region. The study suggests that proper planning, policy recommendations and management of ecosystems will help reduce landslides and mountain disaster occurrences.
