Social-ecological indicators and framework for assessing the sustainability of shrimp farming in coastal Bangladesh

Abstract

Shrimp farming is a major global aquaculture activity; however, its social and ecological impacts raise sustainability concerns. While previous research has focused on isolated social or environmental aspects of sustainability in shrimp farming, integrated assessments of these factors using a social-ecological systems (SES) approach are rare. A framework for assessing the sustainability of shrimp farming—comprising a set of social and ecological indicators—is developed and conceptualized in this study for the first time, using an integrated, interdisciplinary, and empirical SES approach. We first identified key social and ecological indicators and developed a conceptual framework based on SES approach, then surveyed 90 shrimp farms across 3 coastal regions (including Satkhira, Bagerhat, and Cox’s Bazar districts) in Bangladesh. Nearly all farmers in Satkhira (97%) and all in Bagerhat (100%) expressed dissatisfaction with the decreasing pattern of shrimp production and profitability over the last decade. In contrast, nearly all respondents in Cox’s Bazar (97%) reported satisfaction with increasing shrimp production. Except in Cox’s Bazar, equity in labor payment remained a concern for the social sustainability of the shrimp farming system. The changing pattern of shrimp production and profitability, which does not ensure equity, poses a threat to the sustainability of shrimp farming. Most of the surveyed farmers recognized the mutual benefits of mangrove forests and shrimp farming (97% in Satkhira and 77% in Cox’s Bazar), which suggests potential for the development of policy on integrated mangrove-shrimp farming with community-based management. This research could help assess the sustainability of the shrimp farming system and contribute to achieving Sustainable Development Goals 2 (zero hunger) and 8 (decent work and economic growth). By examining existing practices and developing a novel framework, this study highlights informed decision-making and guides methodological discussion on assessing the sustainability of shrimp farming using the SES approach in coastal regions and different aquaculture systems worldwide.
