Diversity of non–conventional vegetables in two ethnic communities of Khagrachari Sadar, Khagrachari, Bangladesh
Abstract
To know the diversity of non-conventional vegetables (NCVs) (both cultivated and wild) in two tribal villages of Khagrachari Sadar, Bangladesh a field survey was conducted from July 2018 to April 2019. The survey was conducted with a semi-structured questionnaire and data was collected from 60 households (thirty from each) selected consistent with farmers category. From the two villages, we found 72 species under 35 families and 61 genera were used as NCVs round the year though availability increases in winter season. The best contributing family was Araceae (7 species) followed by, Lamiaceae (6), Apiaceae, Asteraceae and Cucurbitaceae (5 species each) then on and rest 22 families with just one species. Dioscorea (4 species) was the best contributing genera followed by Colocasia, Cucumis and Solanum (3 species each), Amaranthus and Pogostemon (2 species each) and rest of genera represent with single species. These vegetables mostly collected from wild (68.1%) by ethnic people for their daily consumption and most of them were herbs (68.1%). 2.8 percent each of the recorded species were endangered, vulnerable and near threatened. Among these vegetables, Cucumis hystrix and Asparagus recemosus endangered (EN) condition. Besides this Cucumis melo and Homalomena aromatica vulnerable while Dioscorea bulbifera and Musa ornate were near threatened. In both locations, small farmers used a bigger diversity of non-conventional vegetables. Not for food quality, NCVs also make a big contribution to the tribal people’s nutrition throughout the entire year especially wild NCVs.

Prospects of community based eco-tourism in Sundarbans: a case study at Munshiganj, Satkhira, Bangladesh
Abstract
Nature-based tourism is accelerating with time throughout the world; meanwhile, Sundarbans has considered as one of the best nature-based tourism sites in Bangladesh whilst tiny local peoples participate in this tourism sector. This study examines the prospect of community-based ecotourism (CBET) in the study area for booming local people's participation. This study deals with environmentally responsible travel and visitation to relatively undisturbed natural areas that promote the conservation of nature with local people's involvement. The livelihood of locals in this area will be improved by increasing income opportunities through community-based ecotourism. We noticed the massive advancements of eco-tourism in Munshiganj at Shymnagar, Satkhira district while, the major portion of peoples were interested in getting them involved in ecotourism which can lessen the direct pressure on Sundarbans. Maximum peoples (96.3%) in the study area were attracted for involving and feel interested in working for community-based ecotourism like the house owners (20.73%), guides (20.73%), and boatmen (18.61%), also, they explained that no social, cultural and religious obstacles for developing CBET in this area. Well-planned tourism like CBET could provide economic and political incentives for proper management and conservation of Sundarbans.

Microbial components and physio-chemical parameters of river Ganga, Prayagraj and Varanasi, Uttar Pradesh
Abstract
Ecology of the rivers has become vulnerable after exploitation for years. The study includes measurements to monitor the relevant physio-chemical and biological indicators of pollution in the aquatic system chosen, assessment of the contaminated states of the system, and estimating the efficiency of the system to assimilate the existing pollution load. The results of the study on the physio-chemical parameters of water from ten different locations in two cities Prayagraj and Varanasi of the River Ganga are concluded as the Temperature, pH, EC, Alkalinity, Total hardness, Ca Hardness were observed under the permissible limit. Parameter such as DO, BOD, Mg Hardness is high and above the permissible limit at Prayagraj. Range of Total Dissolved Solids and Turbidity is beyond the allowed limits for both Cities. The outcomes of this learning on physio-chemical parameters of sediment from ten different spots at two places i.e. Prayagraj and Varanasi of the River Ganga are concluded as the Temperature, pH, EC, and Percentage Organic Carbon were under the fair category except for pH at Varanasi which shows slightly acidic nature and Organic Carbon at Varanasi also shows high range. The overall results of the parameters show that the aquatic system of river Ganges is polluted and continues further degrading at a higher rate at both the cities i.e. Prayagraj and Varanasi. A total of 49 species of microorganisms was identified during the study. In Prayagraj aquatic habitat Amphipod was recorded as a dominating group of microorganism’s communities over the others. Whereas in Varanasi, Rotifer and Ostrocoda were recorded as a dominating group of microorganism community over the others. In both the aquatic habitats Protozoa was recorded as the least dominating group of microorganism’s communities. The presence of few dominant species were i.e., Volvox, Branchionus & Colpoda along with significantly more BOD & percent Organic Carbon revels greater organic pollution at Varanasi. On the other hand, the dominant species at Prayagraj were, Daphnia, Amoeba, Copipoda & Hartmanella along with high turbidity, DO & Hardness.
Key Words: Prayagraj, Varanasi, Aquatic ecosystem, Pollution and Microrganism.

Germination and initial seedlings growth response of Ehretia serrata in different Pre-sowing treatments
Abstract
The study was investigated to inspect the effect of different pre-sowing treatments on germination and initial growth performance of Ehretia serrata seeds at the nursery of Chittagong University, Bangladesh. Seeds were treated to six pre-sowing treatments e.g. Control (T0), seeds immersed in hot water for 1 min (T1), seeds treated with sandpaper rubbing (T2), immersed in hot water for 30 sec (T3), immersed in cold water 24 hours (T4), immersed in H2SO4 for 30 sec (10% solution) (T5). Forest topsoil and fine Sylhet sand were used as growing media. As seeds were very tiny in size, germination trays were used to make the experiment convenient. Germination percentage (78.43 %), germination uniformity (0.0235), and germination value (4.8630) were recorded highest in T5 treatment (immersed in 10% H2SO4 and significantly (P< 0.05) different from other treatments. Maximum shoot height (11.34 cm) and root height (9.96 cm) revealed in T0 treatment. Finally, seeds immersed in H2SO4 for 30 sec (10% solution) were found suitable for maximum seedlings production. In the case of vigor seedling production, seedlings raised in forest soil were revealed suitable for Ehretia serrata.
Key Words: Pre-sowing treatments, Germination, Seedling growth, Germination tray, Growing media and Germination value.

Spatio-temporal analysis of land cover changes in the evergreen and semi-evergreen rainforests: A case study in Chittagong Hill Tracts, Bangladesh
Abstract
The main purpose of this study is to describe the spatio-temporal analysis of land use and land cover status and to identify land cover changes, especially of deforestation and degradation in evergreen, semi-evergreen rainforests of Chittagong Hill Tracts from 1988-2018 by using Landsat 8 OLI-TIRS and Landsat 5 TM satellite imagery. The ArcGIS v10.5 and ERDAS Imagine v15 software were used to process satellite imageries and assess quantitative data for land-use change assessment of this study area. The study revealed that the area of forest land and water body decreased by 17.92% and 5.43% respectively from 1988-2018. On the other hand, the area of agricultural land, barren land and settlement increased by 45.66%, 312.08% and 240.01% respectively. If the present condition remains constant, the projection of future land-use/ land cover changes for the next 15 years will predict that more than 7.37% dense forest (2253.83 ha) land will be decreased and 19.60% agricultural will be converted to other land uses. This study suggests that proper policy should be adopted urgently to conserve residual forest coverage and restore it to regain its past appearance.
Key Words: Forest conservation, GIS, Land use, Remote sensing and Satellite imagery.
