The degraded Chunati wildlife sanctuary (CWS) has undergone various land use changes since 1980s. In this study, land use changes of CWS were assessed from 2005 to 2015 by using Landsat TM and Landsat 8 OLI/TIRS images. The ArcGIS v10.1 and ERDAS Imagine v14 were used to process satellite imageries and assessed quantitative data for land use change assessment of this study area. Maximum likelihood classification algorithm was used in order to derive supervised land use classification. It was fou

Due to inappropriate management and absence of land use planning, land cover change of developing country like Bangladesh is a common phenomenon. This land cover change phenomenon will have its tremendous effect if found at a greater extent on natural habitat area for numerous animal and tree species. In this study, land cover change of Chunati Wildlife Sanctuary (CWS) was assessed from (2005-2015) using Landsat TM (Thematic Mapper) and Landsat 8 OLI/TIRS (Operational Land Imager/Thermal Infrare

A deep interest is evident in carbon sequestration modeling in Bangladesh from the development of several allometric equations to estimate carbon sequestration by plants. It is linked to the evolving carbon offsetting approaches, for example, Clean Development Mechanism (CDM) and the REDD+, which require certifiable estimate of carbon captured by trees and forests. This review compiled a snapshot of state of the art in carbon modeling in Bangladesh. More than half of the published research focus

Natural forest in the Chittagong Hill Tracts (CHTs) of Bangladesh is degrading due to various reasons. Village common forest (VCF) in CHTs is one of the successful forest management schemes without government intervention. This research was conducted in the Komolchori VCF, Khagrachari, Bangladesh to delineate its tree diversity status . A total of 921 individuals belonging to 55 species were found from 25 randomly studied plots. The highest basal area and relative dominance were recorded for Ter

Forest Protected Area (PA) co-management, which integrates local communities in the forest management structures, was started in Bangladesh in 2004 to effectively manage and conserve forest resources. This study has investigated if the initiative has met its objectives. Using NDVI maps, we applied a stratified random sampling framework to identify sample plots. Phytosociological and carbon-sequestration data were collected from two co-managed PAs (Lawachara National Park and Teknaf Wildlife Sanc

Bangladesh Forest Department had undertaken co-management of protected area (PA) initiatives for halting the rapid rate of forest degradation and deforestation in the country. However, only few research has been conducted to assess the effectiveness of co-management. In this study, drawing empirical data from two co-managed PA, namely, Bariyadhala National Park (BDNP) and Hazarikhil Wildlife Sanctuary (HWS), we investigated the impacts of co-management on spatio-temporal patterns of land use and

This study evaluates land-use/cover change (LULCC) and urban expansion in Hathazari Upazila, Chittagong, between 1977 and 2017 using satellite images. Spatial and temporal dynamics of LULCC was quantified using three Landsat images, a supervised classification algorithm, and the post-classification change detection technique through geographic information system. The overall supervised classification accuracy of the Landsat-derived land-use/cover maps ranged from 74% to 91%. The analysis reveale

Water is a crucial input for any production system, and mining is no exception. A huge amount of water is being used in the various phases of mining activities. In the coming decades, the competition in using a sufficient amount of fresh water will become a major hurdle for the mining industry. Water footprint (WF), an accounting framework for tracking the amount of water used to produce a unit of product, can be useful to the mining companies by quantifying their water resource appropriation an
