“…As highlighted in this article, the impacts of excess of NaCl on the populations of bacteria and plants, raises concerns about potential deterioration of water and soil quality due to this pollution. Reports suggested that high salt concentrations could directly reduce microbial diversity and biomass in water and soil (Ruhl et al, 2018; Wichern et al, 2006), potentially leading to severe ecological imbalances (Haider et al, 2009; Weber-Scannell et al, 2007).…”

Textile effluents, although their composition can vary considerably, typically contain high levels of dissolved salts and exhibit wide variations in pH. Ecotoxicological studies regarding the effects of these parameters, however, have been limited owing to the need for sensitive and easy-to-handle bioindicators that require low amounts of sampling, are cost-effective, time-efficient, and ethically endorsed. This kind of study, additionally, demands robust multi-factorial statistical designs that can accurately characterize the individual and combined relationship between variables. In this research, Response Surface Methodology (RSM) was used to calculate the individual and interaction effects of NaCl concentration and pH value of a Simulated Textile Effluent (STE) on the development rate (DR) of the bioindicators: Bacillus subtilis bacteria and Lactuca sativa lettuce. The results demonstrated that the bioindicators were sensitive to both NaCl and pH factors, where the relative sensitivity relationship was B. subtilis > L. sativa. The quadratic equations generated in the experiments indicated that increased concentrations of 50-250 mg L−1 of NaCl caused a perturbance of 1.40%–34.40% on the DR of B. subtilis and 0.50%–12.30% on L. sativa. The pH factor at values of 3–11 caused an alteration of 27.00%–64.78% on the DR of the B. subtilis and 51.37%–37.37% on the L. sativa. These findings suggest that the selected bioindicators could serve as effective tools to assess the ecotoxicological effects of textile effluents on different ecological systems, and the RSM was an excellent tool to consider the ecotoxicological effects of the parameters and to describe the behavior of the results. In conclusion, the NaCl and pH factors may be responsible for disrupting different ecosystems, causing imbalances in their biodiversity and biomass. Before discharge or reuse, it is suggested to remove salts and neutralize pH from textile effluents and, mostly, develop novel, eco-friendlier textile processing techniques.

“…The resulted water-logging causes serious damage to agriculture, forestry, fisheries, physical infrastructures and thereby impact on livestock [14]. The area suffers from scarcity of pure drinking water, sanitation system and utility services, as well as squeezed educational and recreational facilities.…”

Ganges-Brahmaputra Basin provides several wetlands which are resourceful for rearing livestock as to support coastal community and their livelihoods in the Southwest Bengal delta. Water-logging hampers rural livelihood by damaging agricultural crops, plant, trees, grazing land and reducing livestock. Primarily, Tidal River Management (TRM) is introduced by coastal community to manage tidal river-floodplain ecosystem by way of removing water-logging, increasing navigability of tidal river, improving agriculture and biodiversity of tidal basin, and progressing livestock which lead to human wellbeing. The study selects Bhaina tidal basin from Southwest Bengal delta to assess the impact of TRM on livestock and the contribution of livestock to households' income. The authors collected both quantitative and qualitative data through face to face interview, key informant interview and focus group discussion. This research finds that, households own greater number of livestock after TRM scenario than that of before TRM scenario. Duck achieves the top number (604) followed by hen (378) from bird species. In addition, cow encompasses the peak number (274) that tailed by goat number (162) from four-legged animal. Besides, households' income is reduced by 26% during TRM case due to effect of salinity and improved by 50% after TRM case considering before TRM case as the base. Sheep is a newly introduced species (found after TRM event) and buffalo and horse are the rare among selected eight species in the study area. Although grazing land is decreasing due to changing cropping patters, food and fodder are available by improving agriculture and terrestrial biodiversity. The study findings will support policy makers to operate TRM effectively for advancing agriculture, livestock and other ecosystem services to pastoral livelihood in the coastal region.

“…Water logging destroys educational and religious institutions, housing conditions and reduces scope for other utility services. Again reduced land productivity, water pollution, deforestation and depletion of species are the direct consequences of water logging in the South-western region of Bangladesh [10]. It is important to note that water logging affects local biodiversity in that region, which subsequently changes the lives and livelihoods of the people of that area.…”

Water logging significantly affects existing biodiversity in Southwestern region, which has important implication for lives and livelihoods of the people. Collecting primary data through FGD, key informant interview and questionnaire survey from three water logged villages of two Unions of Dumuria and Keshabpur Upazila of Southwestern region, the study reaches to the conclusion that duration of water logging and peoples' response to that situation are two important factors that determine the effects of water logging in the study area. Impacts of water logging on biodiversity in the study area are visible in reduced number of birds, livestock, fisheries, as well as restrained growth of plants and vegetations. The study also finds that water logging affects peoples' well being by narrowing down the livelihood options of the people. Water logging squeezes the scope for maintaining household economy by reducing the number of livestock, fisheries, and restraining the growth of vegetation, fruit trees and timber trees.
