Relational sampling fills critical knowledge gaps in benthic ecosystem characteristics in Nunatsiavut, Canada
Northern coastlines face increasing challenges in marine conservation as climate change, shifting ocean currents, and human activities place pressure on sensitive benthic ecosystems. Nunatsiavut, a sovereign Inuit region in Labrador, Canada, has over 17,000 km of coastline made up of dynamic landscapes featuring high marine biodiversity. There, swift currents, restrictive weather, a prolonged sea ice season, and uncharted seafloors make benthic s…
Good data relations key to Indigenous research sovereignty
Although researchers are committed to Indigenous data sovereignty in principle, they fall short in returning data and results to communities in which or with whom they conduct their research. This results in a misalignment in benefits of research toward researchers and settler institutions and away from Indigenous communities. To explore this, we conducted a case study analyzing the rate researchers returned data to Nunatsiavut, an autonomous are…
Delivering scientific evidence for global policy and management to ensure ocean sustainability
Life depends on the ocean, with societal health, cultural systems and national economies reliant on ocean processes and resources. As ocean resources are used, and humans continue to drive climate change, the benefits from the ocean to society are being diminished. Science must meet the needs of policy and deliver to decision makers the information and tools for identifying pathways that support continued delivery of the benefits society derives …
Social construction of climate change and adaptation strategies among Senegalese artisanal fishers
African Atlantic countries are among the most vulnerable to global climate change (CC). Artisanal fishers are particularly vulnerable to the impacts of environmental change on the fisheries on which their livelihoods depend. Although we found that most fishers accept that CC is occurring locally, most believe that other environmental problems affecting fisheries are more important than CC. Opinions on the causes of CC vary widely according to the…
Are subsidies still relevant in West African artisanal small pelagic fishery? Insights from long run bioeconomic scenarios
Defining a sustainable development target space for 2030 and 2050
With the establishment of the sustainable development goals (SDGs), countries worldwide agreed to a prosperous, socially inclusive, and environmentally sustainable future for all. This ambition, however, exposes a critical gap in science-based insights, namely on how to achieve the 17 SDGs simultaneously. Quantitative goal-seeking scenario studies could help explore the needed systems' transformations. This requires a clear definition of the "tar…
Senegalese artisanal fishers in the apprehension of changes of the marine environment
In the context of climate change, which accentuates the growing scarcity of fishery resources, young fishermen are exploring increasingly remote fishing grounds with the immediate consequence of numerous cases of accidents and disappearances at sea and many human and material losses. Faced with this situation of looking for solutions to prevent accidents, the traditional knowledge of West African fishermen was examined. Semi-structured interviews…
Enhanced monitoring of life in the sea is a critical component of conservation management and sustainable economic growth
Marine biodiversity is a fundamental characteristic of our planet that depends on and influences climate, water quality, and many ocean state variables. It is also at the core of ecosystem services that can make or break economic development in any region. Our purpose is to highlight the need for marine biological observations to inform science and conservation management and to support the blue economy. We provide ten recommendations, applicable…
Expanding ocean observation and climate services to build resilience in West African fisheries
Social networks and seafood sustainability governance
In the early 2000s, the sustainable seafood movement put forward the concept of fishery improvement projects (FIP), a structured multi‐stakeholder approach to address environmental challenges in a fishery and aims to use the power of the market to incentivize change. The intent of the FIP model is to allow fisheries that currently do not meet the MSC standard to maintain market access while working on credible improvements. As such, FIPs have bec…
Assessing the contribution of artisanal fisheries to food security
Artisanal fisheries are an important food source in many developing regions. Quantitative bio-economic models are needed that comprehensively assess artisanal fisheries’ contribution to food security. Our model combines standard resource economics theory with the literature on food systems. It explains impacts of environmental variations and market development on output, prices and ultimately food security. The application to the Senegalese purse…

The Emergence of Social Order by Processes of Typifying
The article argues that Rational Choice approaches are not sufficient to explain the “how” of the emergence of social order. Therefore, the concept of “typifying” according to the theory of Berger and Luckmann is understood as the most important form of establishing social orders between different social actors. A computational model is described that captures the basic features of the typifying process. Each artifical actor consists of two diffe…
Historical evolution and mathematical models
Though there are a lot of approaches to the problem of sociocultural evolution most of them are only one-sided, i.e., they deal only with either social or cultural processes. With few exceptions they are also only informal theories with no formal rigour. In this article we propose a theoretical model which considers both sides of the problem, that is the mutual interdependence of the evolution of social structures and of the culture of a society.…
Social differentiation as the unfolding of dimensions of social systems
We argue that by the use of geometrical concepts it is possible to construct a mathematical model of social evolution, that is a mode] of the theory of social differentiation developed particularly by Habermas and Luhmann. To capture this theory it is necessary to define the concept of dimensions of social spaces. The model is implemented into a hybrid computer program which consists of a stochastic cellular automaton (CA) and a genetic algorithm…
