Coastal zone of Bangladesh is vulnerable to different disasters due to global climate change. However, the vulnerability magnitude and impact of climate change has been hardly assessed focusing livelihood issues. Thus, this study was carried out to assess the impacts of the climate change and to find out the existing adaptation strategies at two villages of Dacope upazila in Khulna district of Bangladesh involving purposively selected 100 farmers. A survey was conducted using a pre-tested structured interview schedule. It was found that the highest proportion of the respondents (77%) belonged to low-income group (˂50,000 BDT i.e., 587.98 USD family-1). Villagers faced water stagnation, flood, high salinity, and severe drought during summer. These natural disasters damaged the crops, livestock, poultry, trees, houses, roads and shrimp water bodies. Probable solutions to mitigate the disasters would be construction of strong bunds, collecting and storing fresh water through digging small farm ponds, using the stored water for irrigation, training for awareness building, invention of alternate sustainable technology, excavation of canals and GO-NGO collaboration. Farmers reported that rainwater harvesting, hanging vegetable gardening, gher/embankment gardening, domestic animal rearing, handicrafts, etc. were some viable livelihood options. Development and release of new crop varieties, protection of the Sundarbans and awareness building through motivation might be some coping strategies for future extreme weather events.

The current pandemic situation impacted severely many spectrum (spheres of life) including the education sector. Nevertheless, there was the use of online technology and methods, but spur in the impetus has been in the recent times. It is paradigm shift from face-to-face class to moving classes online: with lot of opportunities and challenges countered by educator and manifested its effectiveness in learning objectives. This research paper attempted to evaluate the new tools & techniques adopted by the educator. Further the opportunities and challenges faced by educator were recognized. This paper attempted to find the teaching effectiveness using the new pedagogy. An ‘Effective Teaching Methods (ETM) Model’ has been developed to measure the teaching effectiveness towards meeting the learning objectives. Methodology: Quantitative method of data collection was followed; 13 variables were identified for analysis of the opportunities and challenges by the educator. Multivariate Regression (SEM) was used to develop the ‘ETM Model’ along with construction of hypothesis. The results showed that there is a high value in the use of tools and methods by educator, while moving classes online. The ‘ETM Model’ revealed that there exists a convergence between opportunities and challenges for teaching effectiveness.

Modern soft drinks constitute a variety of different products. The high temperature in most nations necessitates a substantial intake of liquids to compensate for the predicted losses from respiration. Fruit juices aid detoxification in humans by utilizing acid, which is an essential universal ingredient of juices. Citric acid is the most widely used acid in juices. Physicochemical and microbiological assessments of packed juices have been conducted in the Chemistry Lab of Bahria University Islamabad. A set of eleven locally manufactured packed juices and nine imported juices samples were collected from four different shopping malls and roadside shops in Islamabad. All the twenty samples were quantitatively analyzed for their microbial contamination and physicochemical properties. First, the samples were subjected to the microbial analysis where they were tested for the total bacterial count, total coliform count, and salmonella and shigella count using Nutrient agar, EMB agar, and S.S agar, respectively. All the collected 20 juice samples were examined separately and individually and then compared with water quality standards given by World Health Organization (WHO) and PAK-EPA. After microbiological assessment of juice samples, they were further analyzed with physical and chemical parameters. Physical parameters such as pH, salts, temperature, electrical conductivity, etc. of the juices have been tested. Chemical parameters such as chlorides and alkalinity of the juice samples have been tested. After the testing, the results have been noted down and further calculations have been generated.

Ants, because of their diversity, abundance, and functional roles in the ecosystem, play a crucial role in understanding the effects of habitat loss and fragmentation on community ecology. Thus, the influence of the structural complexity of the environment on the richness and diversity of ants makes them a potential ecological indicator. Although there exist numerous studies on ant species richness in different countries, such studies are rare in Bangladesh. To fill-up this information gap, the present study was conducted in Lawachara National Park, Bangladesh, a conservation site with abundant natural resources. The purpose of this study was to describe the richness and composition of local ant assemblage in the forest ecosystem and understand their structural diversity on different types of plants and disturbance patterns. Time unit sampling and pitfall traps were used to perform sampling from two different areas, viz, primary forest and secondary forest. A total of 843 ant individuals was identified from 48 species of 17 genera distributed among 6 subfamilies. Myrmicinae was the most abundant ant subfamily in the study area. Most of the species found were from the genus Pheidole. The rarefaction curves showed higher species richness in areas with reforestation. The richness pattern of species found in two areas denoted that vegetation and soil conditions may affect the overall diversity and composition of ants. This can be considered as the first extensive list of ant assemblages from Lawachara National Park. These findings will provide comprehensive data for using ants as bioindicators in natural protected areas.

Wetlands are areas where water covers the soil or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season. The Niger Delta in Nigeria is the largest wetland in Africa and the third largest mangrove forest in the world with three sites listed as Ramsar Wetlands of International Importance. The Niger Delta wetlands and coastal resources are of high monetary significance to the local dwellers and the nation in general. This highly coveted wetland is changing rapidly, raising concern for its attendant implication on the communities relying upon its ecosystem potentials. A comprehensive data of the facilities delivered by wetlands is a significant key for real-time wetland ecosystem management. Existing literatures, were synthesized for this review on the potentials, challenges and prospects of the Niger Delta wetlands. It is pertinent from this review that the Niger Delta Wetland is wealthy in aquatic and terrestrial biodiversity of high financial significance to development of Nigeria, and is being challenged by natural and human activities such as dam construction, logging/lumbering, over-grazing, unrestrained tilling of soil for crop production, wetland reclamation, dredging, oil and gas exploration, over-fishing, invasive plant infestation, pollution, Coastal Infrastructure construction, poverty, droughts, desertification, sand storm, alien invasion, sea rising, erosion, etc. The Niger Delta Wetlands harbor tremendous wealth and supply many services that are necessary for human well-being such as location for spiritual renewal and recreation (eco-tourism), flood control, climate regulation, crop pollination, soil regeneration, raw material, energy, air and water purification; food chain supply, and medicines (Herbal solutions). This review postulates that in view of the immense significance and status of the Niger Delta Wetlands, effective and sequential monitoring be put in place by the establishment of centers of excellence in all universities in the Niger Delta Region with emphasis on studying the rich economic diversity of the wetland using remote sensing and Geographic Information System technologies for efficient conservation and management of the wetland resources.
