“…The use of this tool is justified by its low cost and generation of digital data, which can be easily incorporated into a GIS database. 547 In many countries, the rapid expansion of shrimp farming has caused extensive destruction of mangrove ecosystems [55,56]. The destruction of part of the mangrove area was documented during this study.…”

Despite the economic importance of farmed shrimp, a number of technical, environmental, economic and social problems have been widely reported in the international literature. This paper focuses on the environmental and socio-economic impacts of semi-intensive and intensive shrimp farming in the coastal region of Northeastern Brazil and the identification of options for sustainable production. In this Region, the total area dedicated to shrimp farming is approximately 18,500 ha, of which 5750 ha are located in Ceará State. The estuary of Jaguaribe river has the largest number of shrimp farms in the state of Ceará. Currently, the industry has 64 participating farms with a total area dedicated to shrimp farming of 2411.3 ha. In 2011, the total production was 13,110 tons of shrimp with an average yield of 6.3 ton ha −1 ·year −1 in a pond area of 2071.2 ha. This industry employs 2350 people that represent 23.2% of jobs generated in the two municipalities where the Jaguaribe river estuary is inserted. Compared with other countries, Brazil has reduced its exports due to high cost inputs for shrimp farming. However, the Brazilian shrimp industry has benefited from high domestic prices, despite the decreases in international price of shrimp. In 2011, the prices for size category ranged between U$ 4.67 -6.04 for 80/100 (count of head-on shrimp), U$ 4.95 -6.60 for 70/80 and U$ 5.85 -8.10 for 50/60. The major environmental impacts in this industry have focused on the water pollution and loss of mangroves. However, no change in parameters of water quality was observed during the period 2010-2012, indicating that this estuary has some capacity to process pond-derived nutrients while only 3.7 ha of mangrove forests were used to shrimp pond. The results of this investigation demonstrate that Brazilian shrimp industry requires improved management and development policy for a sustainable growth.

“…This is a case of negative externality; neighboring agricultural farmers can suffer reduced crop output (Paul and Ecology and Society 22(3): 5 https://www.ecologyandsociety.org/vol22/iss3/art5/ Vogl 2011). Furthermore, intensive use of shrimp ponds impairs soil quality of the lands in the vicinity of the ponds for an extended period of time (Islam 2003) as well as increases the salinity of groundwater (Deb 1998, Chowdhury et al 2006. A recent study by Soil Resource Development Institute of Bangladesh found that soil salinity expanded to 223,000 hectares of lands in inland polders between 1973(SRDI 2010.…”

ABSTRACT. Modern social-ecological systems are often partly engineered to enhance the robustness (or reduce the variance) of human welfare to environmental fluctuations over a foreseeable time horizon. Recent studies show, however, that subtle trade-offs are usually inherent in such efforts of enhancing short-term robustness. Managing variance on short time scales is likely to be associated with the buildup of hidden fragilities on longer time scales. Using a flood-prone social-ecological system (SES) of coastal Bangladesh as an example, this paper investigates some of the ways in which such robustness-fragility trade-offs can manifest. This SES has been extensively modified in the last few decades through the construction of large-scale flood protection structures (polders) and the introduction of commercial shrimp farming to enhance the robustness of food production to hydrological variability. Our case study analysis of the long-term changes in the SES shows that, although the modifications helped with stability in short time scales, the resulting changes also induced unforeseen problems such as infrastructure maintenance issues, land degradation and sinking, and exposure to market volatility. With this paper therefore we contribute to better understanding of the notion of robustness-fragility trade-offs by illustrating an exemplary case of the phenomenon in the engineered coastal environment context.

Abstract. This study was conducted to characterize the native soil at shrimp Gher and agricultural land in Khulna, Bangladesh, because at present this is a growing concern that the salinity is increasing at an alarming rate. Eight locations were selected and among them five Ghers from south part of Dumuria which is about 60 km away from KUET campus, Khulna, Bangladesh. In the laboratory, various parameters such as salinity, organic content, chloride, pH, alkalinity, conductivity and moisture content were determined by following standard methods. The chloride and alkalinity were determined manually and pH, conductivity and salinity were determined by digital meter. The organic and moisture content both were highest at 30 cm depth for both the cases of shrimp Gher and agricultural land. Chloride was highest at 15 cm depth for both the cases shrimp Gher and agricultural land. Alkalinity was highest at 30 cm depth for shrimp Gher, however, the lowest was for agricultural land. It is concluded that the salinity and organic content vary with depth, age and soil condition.
