“…Soil salinity has been considered a major constraint to food grain production in coastal areas of the country (Huq 1999). The adverse effect of excessive salinity is to raise the concentration of salt in soil solution (Mitro et al 2014). The flow of high saline water enters into the plants by osmosis.…”

Groundwater quality is important as it is the main factor determining its suitability for drinking, domestic, agricultural, and industrial purposes. Hydrogeochemical characteristics of groundwater in coastal aquifers of Patuakhali district have been investigated based on different indices for assessing its utility and to evaluate the factors influencing groundwater quality. A total of 18 groundwater samples were collected from tube wells having depth between 244 and 365 m and were analyzed for physicochemical parameters, including temperature, pH, electric conductivity (EC), total dissolved solids (TDS), salinity; major ion concentrations such as Na ? , K ? , Ca 2? , Mg 2? , Cl -, SO 4 2-, NO 3 -, HCO 3 -, Br -; and trace element concentrations such as As, Pb, Li, Rb, Ba, Be, Co, Mn, Ti, Cd, and Se. The results revealed that the groundwater is slightly alkaline and brackish in nature. The trends of dominant cations and anions are Na ? [ Ca 2? [ Mg 2? [ K ? and HCO 3 -[ Cl -[ SO 4 2-[ NO 3-[ Br -, respectively and Na-Cl-HCO 3 is the dominant groundwater type. Ion exchange and seawater plays a significant role in the geochemistry of the groundwater and signatures of Br -/Cl -ratio showed evidence of mixing of seawater in the southern part of study area. The samples analyzed were also classified with different indices, diagram, and permissible limit i.e., EC, TDS, chloride content, soluble sodium percentage or Na %, sodium adsorption ratio, residual sodium carbonate, magnesium adsorption ratio, Kelley's ratio, Wilcox diagram, USSL diagram and results showed that groundwater is not suitable for drinking and irrigation purpose. However, except for Se and As, the trace metals concentration are within permissible limit.

“…A huge number of precious aquatic organisms are being destroyed by the seed harvesters which are alarming and also a threat to natural food cycle as well. Mitro et al (2014) explained that the extensive farming systems negatively expedite the processes: infringement of mangroves, intrusion of salinity, degradation of land, destabilization of coastal ecosystems. The major socio-economic effects challenge the patterns of livelihood pattern, displacement of family and social structure, internal migration, and livestock (Prodhan et al, 2017;Sarker, 2017).…”

As an indicator of economic development, GDP remains the main factor among economists. But the hidden reality is that such parameter just shows the overall superficial economic gain but not the real development scenario of the masses. In the name of economic development, numerous degrading activities take place in the centre and periphery regions of Bangladesh. Such unplanned development activities are not only halting the natural flow of development but also creating a threat to sustainability. As the shrimp sector emerges as one of the major areas of earning foreign currency, stakeholders overlooking its multiple negative impacts on the coastal environment and traditional economic livelihood. With the introduction of shrimp cultivation different short of income sources created. As a result, some profit seekers become well off within a short period of time leaving majority unprivileged. Moreover, there is no local authority that shows any concern on the long-term suffering of the local inhabitants. In this article, we tried to show the amalgamate opinion of multiple people from different occupational groups and the conflicting areas against popular theory of development. As the research is heterogeneous in nature we used qualitative method for collecting data from various respondents. The research result clearly shows the conflicting situation and deprivation of the local inhabitants. Concluding part of this research focused on the ultimate crisis and its way out.

“…As a result, shrimp farming has caused concerning socio-economic and environmental impacts (FAIRR, 2019;Galappaththi & Berkes, 2015;Mitro et al, 2014;Saha, 2017). For example, the Ministry of National Development Planning (BAPPENAS) in 2014 reported that many aquaculture business entities in Indonesia have not yet implemented Good Aquaculture Practices (Bappenas, 2014).…”

Shrimp farming has contributed a large share in Indonesia’s aquaculture portfolio for at least a decade, and a national plan to increase shrimp production by 250% has been recently laid out. However, boosting shrimp productions could lead to unintended consequences in environmental and socio-economic negative impacts. The rapid development of vannamei farming in Java has increased coastline land clearings and demands of fertilizers, feeds, and chemicals to sustain the farming activities. Such pressures will eventually lead to a reduced environmental capacity and the farming efficiency itself. This study aimed to study the environmental impacts and business performance of intensive shrimp farming in Indonesia. The study was conducted in Aquaculture Business Center (ABC) in Karawang for four months, from July to October 2020. In-situ and ex-situ measurements of water quality parameters were done at six sampling stations directly post-harvest water discharge. The measured parameters consisted of temperature, pH, dissolved oxygen, ammonia (NH3), nitrite (NO2), nitrate (NO3), phosphate (PO4), alkalinity, and salinity. Pollution Index (PI) was used as the primary method to determine the environmental impacts of the shrimp farming. The R/C Ratio was used to analyze the business performance of the company. The results showed that the water quality index in the ABC area was categorized as lightly polluted in station 1 (PIj 4.52) and station 5 (PIj 4.37), moderately polluted in station 2 (PIj 6.24), station 3 (PIj 6.72), and station 4 (PIj 6.13) and heavily polluted in station 6 (PIj 111.06). The determined R/C ratio was 1.10, meaning that the shrimp farming is classified as economically profitable. Although the shrimp farming’s economic performance value is very good, the water conditions affected by waste from the shrimp pond culture will reduce the R/C ratio in the future if not properly managed.
