Abstract The South Pacific bay scallop Argopecten purpuratus represents a high‐value species harvested along the Peruvian and Chilean coastline for more than 60 years. Following strong El Niño event of 1983/84, both countries experienced boom in fisheries, but catches dropped as soon environmental conditions normalized. Aquaculture production began Chile, which dominated Latin American market 1990s. remained small until early 2000s, has increased dramatically ever since, with single location...
Abstract Ocean sustainability initiatives – in research, policy, management and development will be more effective delivering comprehensive benefits when they proactively engage with, invest use social knowledge. We synthesize five intervention areas for engagement collaboration with marine scientists, doing so we appeal to all ocean science disciplines non-academics working industry, government, funding agencies civil society. The are: (1) Using ethics guide decision-making, (2) Improving...
Abstract In February and March 2017, a coastal El Niño caused extraordinary heavy rains rise in water temperatures along the coast of northern Peru. this work, we document impacts phenomenon on artisanal fisheries scallop aquaculture sector, both which represent important socio-economic activities for province Sechura. Despite perceived absence effective disaster management rehabilitation policies, resource users opted wide range different adaptation strategies are currently striving towards...
Abstract Marine traffic is the main vector for marine non‐indigenous species (NIS) that may hitchhike in ballast water tanks or attached to vessel hulls. Understanding dynamics and estimating associated risk of NIS dispersal reveals points leverage preventive management. This study presents a method quantify ship hull fouling‐mediated identifies hubs networks. We use Galapagos Reserve (GMR) as case test applicability this method. Ship position data derived from automatic identification...
Abstract With ever-expanding marine aquaculture, calls for sustainable development become louder. The concept of aquaculture carrying capacity (CC) emerged 30 years ago to frame development, though so far, most studies have focused on the production and ecological components, leaving aside social perspective. Often, estimations are carried out a posteriori, once is already in place, hence ignoring relevant voices potentially opposing onset implementation. We argue that CC should be...
Abstract Ecosystem models, such as Ecopath with Ecosim (EwE), are useful tools for developing ecosystem-based management strategies. Model development, however, requires data the estimation of input parameters including time series calibration. Most small-scale fisheries lack information, making it difficult to reliably use ecosystem models strategy exploration. This is case Chwaka Bay fishery (Zanzibar), where an increase in dragnets has led concerns unsustainable development. While EwE...
Abstract Abrupt environmental change, such as sudden shifts in temperature or salinity, can severely alter the functioning of marine ecosystems and cause dramatic impacts on associated social systems. Resource users, who rely ecosystem services provided by ocean, are particularly vulnerable to drastic events. Functioning relationships (social capital) have recently been suggested a key driver for recovery after disaster. Here, we study how small-scale fishers conduct sea-ranching Peruvian...
In this article, we conduct a social-ecological network analysis of SCUBA tourism human–environmental interactions in the Gili MATra Marine Park Indonesia. Network methodologies are being increasingly applied, but study represents – to our knowledge first example focusing on governance sector. We developed novel mixed methodology for data collection, integration and analyses specific understand human–nature interactions. This includes interviews with business operators, use secondary reef...
Dive into the incredible world of ocean, a place full wonder and beauty! The ocean is like superhero, providing us with tasty seafood other vital “services”. But trouble looms: climate change, plastic pollution, intensive fishing endanger ocean’s superpowers. Your help needed to save day! To keep healthy, we must understand how it works. Get ready explore its mysteries through gigantic “webs” interactions that reveal are connected our actions impact environment, environment affects us. These...
In the face of global change, exploration possible futures marine social-ecological systems (MSES) becomes increasingly important. A variety models aims at improving our understanding ecosystem dynamics and complexities by assessing how react to internal external drivers change. However, these are often built from a natural-science perspective through reductionist top-down knowledge production process that does not engage with interests, concerns stakeholders. Our work explores different...
The coast of Peru lies within the tropics under influence cold, nutrient-rich waters Humboldt Current and interannual onslaught El Niño phenomenon. Peruvian upwelling system is exceptionally productive comprised subsystems at different scales along coast. We aimed to understand differences between two shallow coastal systems a latitudinal gradient: Sechura Bay in north (at convergence tropical waters) Independencia central-south (under typical conditions). compared their biodiversity,...
This paper looks at the institutional emergence, particularly space rights, within culture of Peruvian bay scallop (Argopecten purpuratus) in Sechura Bay. The system developed a period 20 years from an open-access, gold rush scenario to rather structured, formal activity – however, still relies on lot informality. work uses matrix provided by material dependency framework presented this special issue distinguishing between nature, human and hybrid-made materialities that influence emergence...
Abstract We introduce six steps to define a “Window of Tipping Point Analysis” which serves as framework increase the understanding processes and tipping points in social‐ecological systems. apply Window Analysis mathematical model two case studies (i.e., Baltic Sea Humboldt Current Upwelling system), focusing on three aspects. In “to tip or be tipped” we look at agency preventing (or driving) tipping. tipped not discuss intertemporal developments chosen time periods for delineating regime...
