Marine protected areas (MPAs) are valuable tools for marine conservation that aim to limit human impacts on marine systems and protect valuable species or habitats. However, as species distributions shift due to ocean warming, acidification, and oxygen depletion from climate change, the areas originally designated under MPAs may bear little resemblance to their past state. Different approaches have been suggested for coping with species on the move in conservation. Here, we test the effectiveness of different MPA designs, including dynamic, network, and different directional orientations on protecting shifting species under climate change through ecosystem modeling in a theoretical ecosystem. Our findings suggest that dynamic MPAs may benefit some species (e.g., whiting and anchovy) and fishing fleets, and these benefits can inform the design or adaptation of MPAs worldwide. In addition, we find that it is important to design MPAs with specific goals and to account for the effects of released fishing pressure and species interactions in MPA design.

In this paper, we identify three literature‐based hypotheses about how and whether Fairtrade labeling delivers its advertised benefits: a market mechanism that provides producers in developing countries advantaged access to consumer markets; a sustainable agriculture mechanism that improves the sustainability of Fairtrade products and a social justice mechanism that protects the rights and livelihoods of farmers and workers. We surveyed a broad cross‐section of Fairtrade‐certified producer organizations and compared their expectations with their satisfactions using an importance–performance analysis (IPA), principal component analysis (PCA) and ordered logit regression analyses. According to our results, Fairtrade producers report both high importance and high performance in terms of metrics such as empowering women, democratic decision‐making and reduction of child labor, suggesting that farmers are most satisfied with Fairtrade as a social justice mechanism. Fairtrade producers report high importance but lower performance of Fairtrade as a market mechanism and least satisfaction as a sustainable agriculture mechanism. We explore the drivers and implications of these findings for Fairtrade and provide recommendations to increase producer satisfaction.

Because national governments have limited power to regulate the conditions of production abroad, voluntary certification schemes have come to play a significant role in transnational regulation of many global supply chains, particularly in the food sector, where multiple regulatory issues are in play and different certification schemes compete. However, we still know relatively little about the political-economic factors that shape the construction of certified citrus markets for these competing standards.Based on an original dataset from a comparative survey of US and Dutch importers, this paper investigates factors that shape the construction of certification markets for citrus, focusing on the construction of markets for different kinds of certification schemes including Fair Trade, Organic, and GlobalGAP certification. The paper investigates from a comparative perspective whether the construction of markets differs across the US and Dutch political economies. The results show both the enduring effects of national political economies and the importance of global value chain dynamics. Across competing schemes, the industry-sponsored business-to-business certification systems have outcompeted consumer-facing label systems.

Overconsumption of resources and consumer items is an important driver for environmental degradation and climate change. Malls, shopping, and conspicuous consumption are deeply ingrained in the local values and the global image of the United Arab Emirates (UAE). The UAE has a diverse and international population with over 85% expats and numerous opportunities to reduce environmental impact. Increased participation in a circular economy that aims to reduce resource use by recycling materials, reusing products, extending their lifespan, and maintaining their economic value would be an effective strategy to reduce negative environmental impacts. However, little is known about how much and why UAE citizens and residents participate in the circular economy. Therefore, it is important to examine the factors that predict participation in the circular economy in the UAE. To investigate this question, we surveyed n=163 undergraduate students at an American-curriculum university in the UAE and explored literature-based explanations as predictors for participation in the circular economy, namely gender, nationality, exposure to circular economy initiatives, efforts to reduce ecological footprints, and sustainable consumer behaviors using index-based negative binomial regression models. We also compare differences in ways and levels of participation in the circular economy between UAE citizens and residents with t-tests. Our results suggest that participation in the circular economy does not emerge from concerted efforts to reduce environmental degradation such as lowering ecological footprint and reducing waste, but rather investments in sustainable and durable items. Emirati citizens are more likely to participate in the circular economy, in particular repairing items, than expat residents. These differences are most likely to be explained by the more stable lifestyles of Emirati citizens as opposed to the more itinerant lifestyles of expat residents.
