Policies aimed at reducing wildlife-related conflict must address the underlying causes
Multisensor satellite technologies reveal large-scale illegal fishing in some of the world’s least monitored waters.
Abstract Climate-driven redistribution of tuna threatens to disrupt the economies Pacific Small Island Developing States (SIDS) and sustainable management world’s largest fishery. Here we show that by 2050, under a high greenhouse gas emissions scenario (RCP 8.5), total biomass three species in waters ten SIDS could decline an average 13% (range = −5% −20%) due greater proportion fish occurring seas. The potential implications for 2050 include purse-seine catch 20% −10% −30%), annual loss...
Abstract Calls to address social equity in ocean governance are expanding. Yet ‘equity’ is seldom clearly defined. Here we present a framework support contextually-informed assessment of governance. Guiding questions include: (1) Where and (2) Why being examined? (3) Equity for or amongst Whom ? (4) What distributed? (5) When considered? And (6) How do structures impact equity? The supports consistent operationalization equity, challenges oversimplification, allows evaluation progress. It...
While most research has focused on the legality of global industrial fishing, unregulated fishing largely escaped scrutiny. Here, we evaluate nature squid fisheries using AIS data and nighttime imagery globalized fleet light-luring vessels. We find that this fishery is extensive, 149,000 to 251,000 vessel days annually, effort increased 68% over study period 2017–2020. Most vessels are highly mobile fish in multiple regions, (86%) areas. scientists policymakers express concerns declining...
Aquaculture now supplies half of the fish consumed directly by humans. We evaluate whether aquaculture, given current patterns production and distribution, supports needs poor food-insecure populations throughout world. begin identifying 41 seafood-reliant nutritionally vulnerable nations (NVNs), ask aquaculture meets human nutritional demand via domestic or trade, indirectly purchase rich dietary substitutes. find that a limited number NVNs have domestically farmed seafood, those, only...
Abstract Inaccurate or incomplete diagnosis of the root causes overfishing can lead to misguided and ineffective fisheries policies programmes. The “Malthusian narrative” suggests that is driven by too many fishers chasing few fish fishing effort grows proportionately human population growth, requiring policy interventions reduce fisher access, number fishers, population. By neglecting other drivers may be more directly related pressure provide tangible levers for achieving sustainability,...
The Pacific food system has become progressively more integrated into global regimes. This integration had impacts on availability and consumption of food, population health, vulnerability to external drivers. We describe major elements the contemporary provide a foundation for analysis transitions public health outcomes. Although crop production doubled in last fifty years, it not kept pace with growth. deficit is increasingly filled by imported foods, particularly staples, meat sugar....
Capacity development is a major priority in the United Nations Decade of Ocean Science for Sustainable Development (the Decade). Persistent disparities ocean science capacity illustrate substantial challenges to achieving Decade's stated goal eradicating inequality. We argue that new conversation about essential success and beyond. question meaning, motivations, pathways measurement at this critical juncture. While we do not propose single answer these context- situation-specific questions,...
The impacts of deep seabed mining on people have not been sufficiently researched or addressed. Using a legitimacy framework, we discuss the social-equity dimensions this emerging industry in ocean commons.
Recognized as an emerging global crisis in the mid-1990s, “nutrition transition” is marked by a shift to Western diets, dominated highly processed, sugar-sweetened, and high caloric foods. Occurring parallel these health transitions are dramatic shifts natural systems that underlie food availability access. Traditionally, environmental degradation ecosystem change, processes of nutritional transition, though often collinear potentially causally linked, have been addressed isolation. Food...
Ensuring healthy and sustainable food systems in increasing social, economic, ecological change is a key global priority to protect human environmental health. Seafood an essential component of these critical source nutrients, especially coastal communities. However, despite rapid transformations aquatic systems, our urgent need understand them, there dearth data connecting harvested production actualized consumption. Many analyses suggest institutional, legal, or technological innovations...
Aquatic invertebrates are a diverse, nutrient-dense, and socio-ecologically important food whose contribution to human nutrition is frequently overlooked. We quantify their global nutrient supplies estimate the content of >50,000 macroinvertebrate species. Current aquatic invertebrate production equivalent annual requirement for >6 billion people in terms vitamin B12 selenium; >1 copper, omega 3 fatty acids, iodine zinc; >100 million nutrients such as vitamins B2 B3, iron,...
Resource allocation is a fundamental and challenging component of common pool resource governance, particularly transboundary fisheries. We highlight the growing importance in fisheries comparing approaches five tuna Regional Fisheries Management Organizations (tRFMOs). find all tRFMOs except one have defined resources for outlined principles to guide based on equity, citizenship, legitimacy. However, fall short applying these assigning fish resources. Most rely historical catch or effort,...
Ensuring the long-term sustainability of tuna, billfish, and other transboundary fisheries resources begins with data on status stocks, as well information concerning who catches what fish, when, where, how. Despite recent improvements in monitoring surveillance, such dynamics remain poorly understood across high seas. Here we delineate describe pelagic longline activity Pacific Ocean using a framework that integrates descriptive vessel tracking species-specific catch reports. When parsed by...
Accounts of fishing conflicts have been rising globally, particularly between small-scale and industrial vessels. These involve verbal or physical altercations, may include destruction boats, assault, kidnapping, murder. Current scholarship around industrial/small-scale theorizes them as a form resource conflict, where fish scarcity is the dominant contributor to conflict competition. Alternatively, be driven by spatial competition, concentrating there are increased encounters, unrelated...
Abstract Marine fisheries in African waters contribute substantially to food security and local economies coastal nations. Recently, there are growing concerns about the sustainability of living marine resources these countries’ exclusive economic zones (EEZs) due increased risks from climate change, pollution potential over‐exploitation by non‐African (foreign) countries. To effectively manage fishing activities sustain waters, we need useful tools for characterizing waters. Here, assess...
The focus on flag States for the purpose of attributing fisheries catch is inconsistent with assignment sovereign rights to coastal under international law and undermines equity in contemporary quota allocation negotiations. We propose modernizing reporting frameworks include zone-based fish catches more equitably present data, ensure consistency Law Sea, better support realization by developing their development aspirations consistent SDG 14, Life Below Water. are already required collect...
