Consistency in conservation: Marine protected areas (MPAs) are now well established globally as tools for conservation, for enhancing marine biodiversity, and for promoting sustainable fisheries. That said, which regions are labeled as MPAs varies substantially, from those that full protect marine species and prohibit human extraction to those that permit everything from intensive fishing to mining. This inconsistency can in some cases inhibit both conservation and quantifying the proportion of the marine environment that is truly protected. Grorud-Colvert et al . review the consistency of MPAs and propose a framework by which levels of protection can be evaluated and improved. —SNV

How can ocean governance and science be made more equitable and effective? The majority of the world’s ocean-dependent people live in low to middle-income countries in the tropics (i.e., the ‘tropical majority’). Yet the ocean governance agenda is set largely on the basis of scientific knowledge, funding, and institutions from high-income nations in temperate zones. These externally driven approaches undermine the equity and effectiveness of current solutions and hinder leadership by the tropical majority, who are well positioned to activate evidence-based and context-specific solutions to ocean-sustainability challenges. Here, we draw together diverse perspectives from the tropics to propose four actions for transformational change that are grounded in perspectives, experiences, and knowledge from the tropics: 1. Center equity in ocean governance, 2. Reconnect people and the ocean, 3. Redefine ocean literacy, and 4. Decolonize ocean research. These actions are critical to ensuring a leading role for the tropical majority in maintaining thriving ocean societies and ecosystems.

Lifestyle migration, the flow of relatively affluent people from developed to developing countries, is characterized by the search for ‘lifestyle’ destinations with warm climates, reduced costs of living, and perceived higher quality of life. Mexico, Costa Rica, and Panama are three current major lifestyle migration destinations in Latin America. In this article I explore the emergence of this relatively new phenomenon in the Bocas del Toro Archipelago in Northwestern Panama by discussing the contradiction between lifestyle migrants’ idealized perception of place and local realities. I also introduce the implications of these contradicting versions of reality, and how they play out at the local level. Results show that, in general, foreign residents are attracted to Bocas del Toro as a physical manifestation of globally produced images and perceptions of tropical island living. However, an in-depth exploration reveals contradictions between expectations and reality. I suggest that foreigners exhibit a set of attitudes and behaviors towards their new home that are defined by a shared cultural and economic background that, on the ground, contribute to the creation of emerging markets, land conflicts, and changes in environmental practices. The ensuing narrative is contingent upon tensions between and within social, political, and ecological variables at the global and local levels.

Recent decades have seen a rapid increase in the diversity of ocean uses and threats, leading to the Anthropocene ocean: a place fraught with challenges for governance such as resource collapse, pollution, and changing sea levels and ocean chemistry. Here we review shifts in ocean governance regimes from the United Nations Convention on the Law of the Sea, the first legal regime for the global ocean, to Sustainable Development Goal 14 and beyond. This second period represents a merging of growing international interest in the ocean as part of the global sustainable development agenda—characterized by a focus on knowledge, collaboration, and the formation of alliances between diverse actors and institutions of environmental governance. To conduct this review, we analyzed literature on changing actors, regimes, and institutional arrangements for ocean governance over time. We conclude with a summary of challenges and opportunities for future ocean governance.
