Global commitments to conservation and sustainable development increasingly demand sensitivity to the rights and territories of Indigenous peoples and local communities. However, existing tenure systems are often overlooked by global actors and their initiatives. Using key informant surveys, literature, and established databases, we describe 62 dis...

Funding decisions influence where, how, and by whom conservation is pursued globally. In the context of growing calls for more participatory, Indigenous‐led, and socially just conservation, we undertook the first empirical investigation of how philanthropic foundations working in marine conservation globally engage communities in grant‐making decis...

Coastal small-scale fishing (SSF) communities increasingly face an untenable competition for ocean space, while it is recognized securing SSF access to marine resources is key for their sustainable development. Can preferential access areas (PAAs)—a relatively understudied policy tool—address this tension? We provide the first global review of the...

As global change accelerates, natural resource-dependent communities must respond and adapt. Small-scale fisheries, essential for coastal livelihoods and food security, are considered among the most vulnerable of these coupled social-ecological systems. While previous studies have examined vulnerability and adaptation in fisheries at the individual...

Calls to transform food systems along more ethical and sustainable lines are mounting alongside debates about what constitutes transformative change and strategies needed to achieve it. Civil society organizations (CSOs) have argued that transforming food systems requires transforming the governance of food systems, as dominant “productivist” appro...

The world’s fisheries face complex and high-stakes governance problems that increasingly require mobilizing diverse collectives of governance actors. How fishers and fishing organizations understand and articulate governance problems has implications for how they engage with governance institutions and the kinds of collective action they enact. In...

Fishing for subsistence constitutes a livelihood safety net for poverty, malnutrition and gender inequality for populations dependent upon aquatic foods around the world. Here we provide global estimates showing that almost the same amount of small-scale fishers engage in subsistence fishing at some point during the year as in commercial employment...

We are in a period of unprecedented growth in conservation philanthropy. How will this influx of private funding affect conservation agendas? Inspired by a collaborative research co-design process, this paper addresses questions about how foundations influence conservation agendas in the places they work. We draw from a case study of the world's la...

Global patterns of management and governance of small-scale fisheries:contributions towards the implementation of the SSF Guidelines

Conservation philanthropy has grown significantly in the past decade. As the number of philanthropic‐supported conservation initiatives increases, so too will the frequency of exits—the ending of funding relationships. A trend toward “strategic philanthropy,” where foundations fund time‐limited grants, is already contributing to near‐constant exits...

Blue foods play a central role in food and nutrition security for billions of people and are a cornerstone of the livelihoods, economies, and cultures of many coastal and riparian communities. Blue foods are extraordinarily diverse, are often rich in essential micronutrients and fatty acids, and can be produced in ways that are more environmentally...

Environmental governance scholars have overlooked philanthropic foundations as influential non‐state actors. This omission, along with the continued growth in funding from private foundations for conservation issues, presents important questions about what foundations do in governance spaces. To address this gap, we examine The David and Lucile Pac...

Poverty and food insecurity persist in sub-Saharan Africa. We conducted a secondary analysis of nationally representative data from three sub-Saharan Africa countries (Malawi, Tanzania, and Uganda) to investigate how both proximity to and engagement with small-scale fisheries are associated with household poverty and food insecurity. Results from t...

There is a scarcity of studies on how to design conservation organizations to improve biodiversity outcomes. We use information from four conservation organizations (African Parks, Australian Wildlife Conservancy, Mauritian Wildlife Foundation, and Rewilding Argentina) to update and describe an organizational framework for effective conservation or...

In this study we examine how fishers negotiate the tensions and tradeoffs between self-governance and reliance on the state. We address this question using the case of cooperative fishers in Mexico, where the government has historically acted as benefactor to local communities while also positioning itself as the key actor holding the capacity to s...

In the ‘new Gilded Age’ of mega-wealth and big philanthropy, academics are not paying enough attention to private foundations. Mirroring upward trends in philanthropy broadly, marine conservation philanthropy has more than doubled in recent years, reaching virtually every globally salient marine conservation issue in all corners of the planet. This...

Small-scale fisheries and aquaculture (SSFA) provide livelihoods for over 100 million people and sustenance for ~1 billion people, particularly in the Global South. Aquatic foods are distributed through diverse supply chains, with the potential to be highly adaptable to stresses and shocks, but face a growing range of threats and adaptive challenge...

Small-scale fisheries and aquaculture (SSFA) provide livelihoods for over 100 million people and sustenance for ~1 billion people, particularly in the Global South. Aquatic foods are distributed through diverse supply chains, with the potential to be highly adaptable to stresses and shocks, but face a growing range of threats and adaptive challenge...

Communities throughout the globe are increasingly being given the responsibility of resource management, making it necessary to understand the factors that lead to success in community-based management (CBM). Here, we assessed whether and how institutional design principles affect the ecological outcomes of CBM schemes for Arapaima sp., an importan...

Marine area-based conservation measures including no-take zones (areas with no fishing allowed) are often designed through lengthy processes that aim to optimize for ecological and social objectives. Their (semi) permanence generates high stakes in what seems like a one-shot game. In this paper, we theoretically and empirically explore a model of s...

Small-scale fisheries are becoming a global social and environmental concern. The contribution of marine small-scale fisheries to global food security and coastal livelihoods, coupled with the significant challenges they face, has attracted increasing attention and aid from environmental organizations, philanthropies, and multilateral agencies over...

Small-scale fisheries (SSF) contribute substantially to global food security, sustainable marine ecosystems and poverty alleviation. Yet many SSF face problems of overexploitation and poverty calling for novel governance approaches that enhance human-wellbeing, equity and ecological sustainability. External policies and interventions to support suc...

Small-scale fisheries’ actors increasingly face new challenges, including climate driven shifts in marine resource distribution and productivity. Diversification of target species and fishing locations is a key mechanism to adapt to such changes and maintain fisheries livelihoods. Here we explore environmental and institutional factors mediating ho...

The international development community is off-track from meeting targets for alleviating global malnutrition. Meanwhile, there is growing consensus across scientific disciplines that fish plays a crucial role in food and nutrition security. However, this ‘fish as food’ perspective has yet to translate into policy and development funding priorities...

Human-driven changes to aquatic environments threaten small-scale fisheries (SSFs). Ensuring a livable future for SSFs in the Anthropocene requires incorporating ecological knowledge of these diverse multi-species systems beyond the long-standing reliance on populations, a management paradigm adopted from industrial fisheries. Assessing the state o...

Scale is a powerful concept, a lens that shapes how we perceive problems and solutions in common-pool resource governance. Yet, scale is often treated as a relatively stable and settled concept in commons scholarship. This paper reviews the origins and evolution of scalar thinking in commons scholarship in contrast with theories of scale in human g...

One strategy for ecological monitoring of protected areas involves data collection by local resource users instead of external scientists. Growing support for such programs comes from their potential to both reduce costs and influence how resource users perceive and support protected areas, but their effects on participants are only beginning to be...

[English below] Cuando se hace referencia al cambio climático, el imaginario colectivo nos hace pensar en el derretimiento de los glaciares o en osos polares famélicos que están a la deriva en un vasto océano sobre un pedazo de hielo minúsculo. Difícilmente nos imaginamos las consecuencias de los problemas ambientales y cómo éstos afectan ya y segu...

Secure property rights are often seen as a precondition of incentives for long‐term sustainable use by communities dependent on natural resources. Securing formal property rights can be challenging in coastal small‐scale fisheries, which often operate under open access conditions. We argue that insecure, informal rights can offer one pathway for pr...

Decentralization of fisheries management in Mexico has created overlapping state agencies without clearly defined responsibilities. This has generated a management dilemma for national fisheries enforcement, due to ambiguity in implementation and legislation among agencies. Through a case study in the Sian Ka'an Biosphere Reserve, in the Yucatan Pe...

Harvesting has received most theoretical, empirical, and policy attention towards understanding common-pool resource dilemmas. Yet, pre-harvesting and post-harvesting activities influence harvesting outcomes as well. Broadening the analytical focus beyond harvesting is needed to imagine new ways of theorizing and governing the commons. Fishing—whic...

The sustainable governance and management of small-scale fisheries (SSF) is challenging, largely due to their dynamic and complex nature. Agent-based modeling (ABM) is a computational modeling approach that can account for the dynamism and complexity in SSF by modeling entities as individual agents with different characteristics and behavior, and s...

Highlights • Fishermen use lies and ruse to bond, complicating notions of trust in CBNRM and favoring critical theories of social capital. • Joking deceptions help men draw social boundaries and maintain harmony amidst competition for natural resources. • Analysis of gendered social capital and masculinity reveals norms that shape resistance to...

The importance of understanding how social-ecological interdependencies deriving from global trade influence social-ecological sustainability has been argued for decades. Even if substaintial progress has been made, a research gap remains regarding how small-scale fish buyers, whos daily operations have implications for the livelihood of more than...

Small-scale fisheries (SSF) have long been overshadowed by the concerns and perceived importance of the industrial sector in fisheries science and policy. Yet in recent decades, attention to SSF is on the rise, marked by a proliferation of scientific publications, the emergence of new global policy tools devoted to the small-scale sector, and conce...

In the coming decades, accelerating processes of climate change are expected to impact the world’s fisheries. These changes will likely exacerbate ongoing challenges in the governance of small-scale fisheries, which play a significant role in supporting livelihoods and food security throughout the world. Among fishers in Mexico, the perceived impac...

Wildlife hunting is essential to livelihoods and food security in many parts of the world, yet present rates of extraction may threaten ecosystems and human communities. Thus, governing sustainable wildlife use is a major social dilemma and conservation challenge. Commons scholarship is well positioned to contribute theoretical insights and analyti...

The expansion of global seafood trade creates opportunities as well as risks for small-scale fisheries (SSFs) livelihoods. Markets provide economic opportunity, but without effective governance, high demand can drive resource degradation. In the context of small-scale sea cucumber fisheries in Yucatán, Mexico, this study documents local governance...

Globally, marine protected areas (MPAs) are prominent conservation tools. Yet, the understanding of their social effects remains limited. Our multimethod approach relied on lab-in-the-field economic experiments (n = 127) in two MPA and two non-MPA communities in Baja California, Mexico. We also deployed a standardized fishers' survey (n = 544) to v...

Introduction: Interrelated social and ecological challenges demand an understanding of how environmental change and management decisions affect human well-being. This paper outlines a framework for measuring human well-being for ecosystem-based management (EBM). We present a prototype that can be adapted and developed for various scales and context...

Because the Anthropocene by definition is an epoch during which environmental change is largely anthropogenic and driven by social, economic, psychological and political forces, environmental social scientists can effectively analyse human behaviour and knowledge systems in this context. In this subject review, we summarize key ways in which the en...

Increasing recognition of the human dimensions of natural resource management issues, and of social and ecological sustainability and resilience as being inter-related, highlights the importance of applying social science to natural resource management decision-making. Moreover, a number of laws and regulations require natural resource management a...

Environmental conservation initiatives, including marine protected areas (MPAs), have proliferated in recent decades. Designed to conserve marine biodiversity, many MPAs also seek to foster sustainable development. As is the case for many other environmental policies and programs, the impacts of MPAs are poorly understood. Social–ecological systems...

In 2012, the World Bank, FAO and WorldFish Center published a review of the economic importance of fisheries entitled Hidden Harvest: The Global Contribution of Capture Fisheries. While providing essential information and estimates that are still valid, the analyses would benefit from being refined and updated, and also by including additional dime...

We developed an agent-based model (SMILI) to investigate the interplay between the individuals (micro-level), the organizations (meso-level) and the fishing community (macro-level), and the fish resource they depend upon. The model formalizes empirical hypotheses about self-governance arrangements in SSFs in Northwest Mexico, building on qualitativ...

Small-scale fisheries (SSFs) in developing countries are expected to play a significant role in poverty alleviation and enhancing food security in the decades to come. To realize this expectation, a better understanding of their informal self-governance arrangements is critical for developing policies that can improve fishers’ livelihoods and lead...

Marine protected areas (MPAs) are increasingly being used globally to conserve marine resources. However, whether many MPAs are being effectively and equitably managed, and how MPA management influences substantive outcomes remain unknown. We developed a global database of management and fish population data (433 and 218 MPAs, respectively) to asse...

The need for strengthening fishers' adaptive capacity has been proposed in the literature as an important component of effective fisheries governance arrangements in the presence of rising numbers of external drivers of change. Within the context of small-scale fisheries, government subsidies have been the main tool used for increasing adaptive cap...

Increased interest in oceans is leading to new and renewed global governance efforts directed toward ocean issues in areas of food production, biodiversity conservation, industrialization, global environmental change, and pollution. Global oceans governance efforts face challenges and opportunities related to the nature of oceans and to actors invo...

Social indicators, both mature and emerging, are underused

Trust and cooperation constitute cornerstones of common-pool resource theory, showing that "prosocial" strategies among resource users can overcome collective action problems and lead to sustainable resource governance. Yet, antisocial behavior and especially the coexistence of prosocial and antisocial behaviors have received less attention. We bro...

Eelgrass (Zostera marina) population estimates show a decreasing trend worldwide in the second half of the twentieth century. Mexico lacks long-term time series to determine trends for major eelgrass populations and has made no conservation efforts. Therefore, we present the first report on the historic presence of this annual coastal ecosystem in...

Public policies are structured by policy designs that communicate the key elements, linkages, and underlying logic through which policy objectives are to be realized. This paper operationalizes and integrates core concepts from the institutional analysis and development framework, including the institutional grammar, the rule typology, action situa...

Significance Meeting human needs while sustaining ecosystems and the benefits they provide is a global challenge. Coastal marine systems present a particularly important case, given that >50% of the world’s population lives within 100 km of the coast and fisheries are the primary source of protein for >1 billion people worldwide. Our integrative an...
