Aquaculture is a major contributor to global food production, but has attracted considerable controversy. Disagreements over the social and ecological impacts of aquaculture (positive and negative) have hindered further expansion of aquaculture production, particularly in wealthy democratic countries. This article presents findings from a series of workshops bringing international aquaculture scholars together from the natural and social sciences to examine and compare social-ecological challenges facing aquaculture development in five nations: Canada, the Faroe Islands, Iceland, Norway, and Sweden. This multinational comparison provides unique insights into common and particular challenges in aquaculture governancea dimension that is missing in current literature about the industry. A political ecology framework from the environmental social sciences is used to examine how natural and human phenomena interact to shape these challenges and frame the conflicts that often result. The analysis reveals a wide range of social-ecological factors limiting aquaculture expansion in the five countries, including access to suitable environments, interactions with other sectors, and policy and regulatory gapsnot only with respect to aquaculture, but also on related issues such as marine spatial planning and the involvement of indigenous peoples in decision-making. The findings provide preliminary guidance for future policy development and comparative aquaculture research. IntroductionAquaculture, the farming of aquatic animals and plants for private harvest, has grown substantially in recent decades and now plays a major role in the global food system. Like landbased agriculture, aquaculture takes multiple forms, from the small-scale stocking of ponds with herbivorous fish for local consumption, to the industrial-scale production of high-value species such as salmon, shrimp, and shellfish for international markets (FAO 2016). Global aquaculture production has grown at rapid rate, from 32 million tonnes in 2000 to 77 million tonnes in 2015 (Zhou 2017). With this growth have come new social and ecological challenges. In developing regions where small-scale freshwater aquaculture is common, issues such as landscape change, water quality, deforestation, and loss of wetlands have been identified as key problems (Bush and Marschke 2014). In wealthier countries, controversy has emerged over impacts on wild stocks and species, degradation of habitat, rural futures and economic restructuring, and legal and moral rights to aquatic spaces and resources (Young and Matthews 2010). These challenges
Purpose -The purpose of this study is to examine where product, process and traceability information is systematically lost at a mineral water bottling plant. It aims to highlight areas where traceability could be improved and to suggest changes that could be made to improve traceability. It also aims to examine the implications of these changes for the current system. Design/methodology/approach -Process mapping was carried out at a mineral water bottling plant to investigate the flow of material and information. The results were analyzed to identify the critical traceability points (CTPs) in the production process where information is lost. Findings -One of the CTPs at the mineral water bottling plant was the lack of a link between product, process and traceability information for the screw caps.Research limitations/implications -This is a study of an individual case, which limits the generalizations that can be made. Practical implications -Procedures need to be established at the mineral water bottling plant in order to achieve traceability. All the information about the resources used in production could be linked to a "best before" date on each mineral water bottle. Originality/value -The authors have found few similar case studies in the published literature. This case study can be of value to other research institutes and industries where the focus is on traceability. It could also be of interest to researchers working with information technology systems, ontology/metadata schemes, cost/benefits analyses and the impacts of traceability. The implications of traceability highlighted in this paper can be of use to regulatory authorities in their decision making processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
