Social-ecological vulnerability to climate change and risk governance in coastal fishing communities of Bangladesh

In Bangladesh, fishing communities are one of the most climate-vulnerable groups, though they play an important role in economic development. The main objective of this study was to identify vulnerability by exploring exposure (i.e., lack of regulating services or household capitals), susceptibility (i.e., lack of access to provisioning services), and lack of resilience (i.e., lack of alternative livelihoods and capacity) and to explore adaptation options, and challenges to understand risk governance. The study considered 45 published research articles for analysis following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Keywords were used in combinations (e.g., fishing communities and Bangladesh) to identify and screen published articles. Articles published in English focusing on vulnerability and/or risk governance, published between 2011 and 2022, featuring original empirical data or a comprehensive systematic review, and published in peer-reviewed journals were included. Articles were excluded if vulnerability and risk governance were evaluated but did not fit or match the definition used in this study. The study found frequent disasters and ocean warming caused different stresses, such as reduced fish catch and income, and resulted in an increased risk of fisheries conflict. Moreover, fishing communities have limited access to properties, modern fishing equipment, financial institutions, and fisher-centered organizations. Adaptation strategies include ecosystem-based (e.g., plantation, payment for ecosystem services) and non-ecosystem-based (e.g., temporary migration, getting help from neighbors) approaches. To boost fish production, the Government of Bangladesh instituted fishing restrictions and social safety net programs (e.g., distributing rice during the fishing restrictions); both initiatives were helpful. However, the conservation policies are not being implemented properly, and there is no particular social welfare, such as banking systems, and low- or no-interest loans being provided that may support fishers to buy fishing equipment or generate alternative income sources. Considering the previous evidence of risks, this paper recommends that fisheries conservation policies be implemented properly, and fishing communities be provided with insurance services and no- or low-interest loans. This will contribute to reducing the climate-induced social-ecological risk and improve sustainable livelihoods that can withstand any regional, national, or local crisis

Tobacco cultivation in Bangladesh: is it a threat to traditional agro-practice?

481-485The impacts of tobacco cultivation on traditional agro-practices and knowledge, food security, agro-biodiversity and socio-economic conditions of a remote hilly tribal community of Bangladesh were investigated. Sixty per cent households were found practicing shifting cultivation compared with 10 yrs back changing local food availability. Local crop varieties were being lost due to low cultivation and weak seed preservation system. Despite better benefits from traditional cultivation, 90% people now fully depended upon tobacco cultivation for significant cash flow at a time. Increasing dependency upon tobacco cultivation is apparently making people economically vulnerable due to potential low sustainability

Reading Nature’s Mind: Disaster management by indigenous peoples of Bangladesh

80-90The paper summarizes the traditional means of forecasting and preparing for 17 natural hazards by the indigenous communities of the Southeastern hilly region of Bangladesh, a region not well-understood in terms of impacts of natural disasters. The study records communities’ perceptions of the frequency and severity of hazards over the last decade and identified

Floating Gardening in Bangladesh: a means to rebuild lives after devastating flood

31-38Floating gardening, a form of hydroponics using aquatic plants as the medium, is a traditional cultivation system in southern Bangladesh practiced for year-round seedling and vegetable production. The livelihoods of marginalized people of the wetlands in North-eastern Bangladesh (haor region) are often constrained by 7-8 months water stagnation due to floods. A pioneering attempt at scaling up floating gardening in this haor region coincided with repeated, devastated floods in 2007. This paper summarizes the endeavour of haor dwellers in overcoming post-flood situation by up-taking this indigenous farming-technique for the first time as a result of intense motivation, capacity development, and determination. Despite some limitations and challenges, floating gardening and subsequent winter vegetable cultivation on soil was found to be useful for improving nutritional security, household income, and land-use capacity of extreme poor, landless people, especially in the post-disaster months. Potentials of floating gardening to adapt to changing climate are also highlighted

Vulnerability and ecosystem-based adaptation in the farming communities of droughtprone Northwest Bangladesh

Agriculture is sensitive to climate change as it depends on temperature and rainfall patterns for crop production. Though Bangladesh's recent growth in its agriculture sector is remarkable, the farmer community living in the northwest region of Bangladesh faces drought every year that negatively affects agriculture, ecology, and society. However, studies focusing on farmer communities' vulnerability to drought and adaptation options through a social-ecological lens are limited. The present study used a framework that combines social-ecological vulnerability (i.e., exposure, sensitivity, and lack of resilience) and ecosystem-based adaptation (EbA) strategies and linked them with risk governance (i.e., organization, planning, and implementation) to understand social-ecological risk and adaptation. Data was collected through 50 in-depth interviews and six focus group discussions with the farmer communities of the Tanore sub-district of Rajshahi district, Bangladesh. We found that increased temperature, lack of water availability, change in rainfall pattern, and limited availability of drought-resilient crop seeds increased farmers’ vulnerability to drought. Farmers were shifting from traditional farming practices to more ecosystem-based, integrated farming practices that are less climate-sensitive. Combined agriculture, selecting drought-tolerant rice varieties, and shifting cropping patterns were some strategies that farmers adopted to address risks. However, the adaptation of these strategies was not well-governed. Farmers opined some strategies that could be initiated at the organization (e.g., local government support), planning (e.g., planning farming skill development), and implementation (e.g., restoring water bodies) levels to help the community to reduce risk. The study would aid in framing governance measures to reduce vulnerability and risk in agriculture-dominated social-ecological systems

Contributions of nature-based solutions to reducing peoples vulnerabilities to climate change across the rural Global South

Nature-based solutions (NbS); working with and enhancing nature to address societal challenges, increasingly feature in climate change adaptation strategies. Despite growing evidence that NbS can reduce vulnerability to climate change impacts in general, understanding of the mechanisms through which this is achieved, particularly in the Global South, is lacking. To address this, we analyse 85 nature-based interventions across the rural Global South, and factors mediating their effectiveness, based on a systematic map of peer-reviewed studies encompassing a wide diversity of ecosystems, climate impacts, and intervention types. We apply an analytical framework of peoples social-ecological vulnerability to climate change, in terms of six pathways of vulnerability reduction: social and ecological exposure, sensitivity, and adaptive capacity. Most cases (95%) report a reduction in vulnerability, primarily by lowering ecosystem sensitivity to climate impacts (73% of interventions), followed by reducing social sensitivity (52%), reducing ecological exposure (36%), increasing social adaptive capacity (31%), increasing ecological adaptive capacity (19%) and/or reducing social exposure (14%). Our analysis shows that social dimensions of NBS are important mediating factors for equity and effectiveness. This study highlights how understanding the distinct social and ecological pathways by which vulnerability to climate change is reduced can help harness the multiple benefits of working with nature in a warming world
