Abstract:The study was conducted to observe the status of fisheries resource of Tanguar haor, one of the large wetland in the north eastern part of Bangladesh. For this purpose the whole study was completed in two parts: interviewing with local people and analyzing the water quality. Indiscriminate harvesting of mother fishes, use of agrochemicals, sedimentation on haor basin and habitat destruction were found as major causes of fisheries resources degradation in the study area. Most of the water quality parameters were found good which were within the standard level set by Government of Bangladesh for fisheries. However, EC and TDS were found higher than the recommended level for fish production.

An investigation was carried out to assess the water qualities and extents of impurities in groundwater and surface water (Padma river water) in Rajshahi City area. Water samples from a total of 330 tube wells and five spots of the river Padma were analysed for physicochemical, biological and hydrological parameters with standard methods. Among all considered parameters of ground water, concentrations of arsenic, iron, manganese, total hardness, and total coliform and faecal coliform bacteria were found above the permissible limits for potable water. In case of the river Padma, biochemical oxygen demand, chemical oxygen demand, total coliform, faecal coliform and suspended solids exceeded permissible limits. Both ground and river water must be treated properly before distribution for drinking purpose. Finally, the Padma is recommended as the most sustainable drinking water source for Rajshahi City Corporation area.

The purpose of this study was to offer a general concept and overview of the textile industry’s environmental sustainability assessment. The textile and garment industries cause environmental damage at every stage of manufacturing, from the cultivation of raw materials through the disposal of finished goods. Chemical loading, high water consumption, high energy consumption, air pollution, solid waste, and odour creation are all key environmental concerns in the textile industry. To achieve sustainable production, it is necessary to examine the performance of the textile sector while considering the three elements of sustainability. To study and locate recent and related works, five keywords were used: environmental; sustainability; eco-design; manufacturer; supply chain management. All through the life cycle of textile products, the textile sector has a substantial environmental impact. This paper illustrates how the textile industry may use strategic ways to improve ecologically sustainable textile product usage and manufacturing. A discussion is focused on how to be increased sustainability in the textile industry. This paper introduces key principles for ecologically sustainable business practices to consider (e.g., eco-design, corporate social responsibility, and green supply chain management). It is critical that all stakeholders in the textile industry, including consumers, producers, environmental protection is emphasized in the manufacture and use of textile goods by the distribution chain and customers.
