The ongoing international negotiations on a global plastics treaty will have pivotal implications for future efforts to transform the plastic economy. This is essential since the current use of plastic in the economy impacts the environment beyond the planetary carrying capacity. To ensure that the forthcoming Treaty can provide the foundation for...

The UN international legally binding instrument on plastic pollution (UNEA resolution 5/14) aims to reduce plastics pollution. However, midstream and downstream assessments show that optimizing waste management, removal technologies, and improved circularity is not sufficient to curb plastics pollution in the short-, mid- or long-term. Therefore, w...

You will find here the supplemental materials of the article “Reducing plastic production: Economic loss or environmental gain?”. The supplemental materials explain how the graphs and the tables of the article were computed based on annual values and on an input-output macroeconomic model designed at the world scale.

We reviewed economic and environmental studies on global plastic pollution and we estimate the global cost of actions toward zero plastic pollution in all countries by 2040 to be US$ 18.3–158.4 trillion (cost of a 47% reduction of plastic production included). If no actions are undertaken, we estimate the cost of damages caused by plastic pollution...

Through the efforts shared in this chapter, we embrace the hypothesis that local representations of our changing climate offer a key angle for facing climate change. We describe the coconstruction processes of climate services in five sites across Europe: Bergen (Norway), Brest, Kerourien (France), Dordrecht (the Netherlands), Gulf of Morbihan (Fra...

Frontiers in Sustainability presents "The Sustainability Series" - a quarterly collection of specialized Research Topics aiming to address global sustainability challenges via open-source, high-quality peer-reviewed research articles. The Plastics Problem, our inaugural series, will focus on the following themes: (1) Investigating Socio-economic D...

Polybrominated diphenyl ethers (PBDEs) were measured in plastic resin pellets collected from 65 beaches across 27 countries worldwide. They were detected at 49 locations at concentrations of the sum of 49 congeners of up to 46 ng/g-pellet and a median of 2 ng/g-pellet. These values are one to two orders of magnitude lower than those of polychlorina...

Rooted in the main CoCLiServ purpose -community dialogue with climate services in order for them to be more meaningful in a place- the modes of representation are rooted in the 5 CoCliServ sites. From the very beginning of the CoCliServ project to its end in June 2021, the partners saw the progressive stabilization of the 3 main modes of representa...

The purpose of this document is • To provide an overview over the results of Work Package 1, Narratives of change; • To critically discuss the role of narratives in the production of place-based climate services for action; • To document the lessons learned from the five case-studies; • To inform the consortium and the respective site organizers fr...

We conducted 5 locally-based Arts and Sciences processes, working closely with local stakeholders, artists, scientists and inhabitants in order to propose for each site a conjoint art–science analysis through shared engagement in the interpretation and representations of the various steps conducted within WPs 1, 2 and 3. We present here the theoret...

Green economic growth led by technological solutions is often mentioned as a solution for mitigating plastic pollution. However, economic growth appears to be in contradiction to planetary boundaries. By developing two worldwide socioeconomic models, for forecasting inadequately managed plastic waste up to the year 2050 across 217 countries and ter...

Marine litter, the majority of which is plastic, is one of the most pressing global environmental challenges impacting the planet. One way coastal communities respond to this challenge is through the environmental stewardship practice of volunteer beach cleanups. Beyond providing temporarily cleaner local beaches, how might these beach cleanups hav...

We developed, tested and refined a novel incremental participatory scenario approach. This method allows for the development of normative scenarios, pathways that lead to desirable futures, with local communities, through a non-linear approach. Developments in the real world rarely follow straightforward linear paths. The approach inventories ‘hing...

Growing from the Zero Plastic campaign in Lanzarote, begun in 2009, the "Zero Plastic" working group was launched in May 2018 at the annual meeting for the World Network of Island and Coastal Biosphere Reserves (WNICBR) in Menorca. The Zero Plastic working group is an alliance between the WNICBR and the Marine Sciences For Society research network;...

The goal of this paper is to analyze how and with what results place-based climate service co-production may be enacted within a community for whom climate change is not a locally salient concern. Aiming to initiate a climate-centered dialogue, a hybrid team of scientists and artists collected local narratives within the Kerourien neighbourhood, in...

Green economic growth fed by technological solutions is often mentioned to mitigate plastic pollution. But economic growth appears to be in contradiction to planetary boundaries. By developing two worldwide socioeconomic models based on non-technological solutions, economic production, social, and policy data, we demonstrate the adverse ecological...

We conducted case studies using a novel incremental scenario approach. With local actors, we co-developed visions of desirable futures, normative scenarios that might lead towards those futures, and inventoried ‘hinge points’: critical moments in time where things might lead to a better or worse future. To bridge the latter, specific information or...

Climate change is causing wide-ranging effects on ecosystem services critical to coastal communities and livelihoods, creating an urgent need to adapt. Most studies of climate change adaptation consist of narrative descriptions of individual cases or global synthesis, making it difficult to formulate and test locally rooted but generalizable hypoth...

This paper contributes to the body of knowledge associated with the analysis of transdisciplinary research. We use a narrative centered approach, focusing on hybridity, sensemaking and the potential for transdisciplinary research to foster agency. When confronted with changes, people – as individuals – and local communities – as groups – make sense...

How can scientific climate knowledge be transformed into locally meaningful knowledge? CoCliServ explores new ways in climate communication and shifts the focus on narratives in order to co-develop new forms of climate services for action. Narratives of change provide local knowledge, they facilitate decision-making, and they help identifying infor...

We explored different issues and trends at play in the case study areas that might be relevant for designing local scenarios. Particularly, we examined both climate-related and non-climate related aspects, and aspects that the local community has considerable influence on as well as those that are largely beyond their control. These different aspec...

The Zero Plastic initiative started in 2008 as a collaborative effort between the UNESCO Biosphere Reserve of Lanzarote and the network of researchers Marine Sciences For Society. From 2008-2013, we identified stakeholder needs, established good trust conditions, and assessed plastic pollution in participating communities. From there we moved to: C...

Do scientific results of climate science in the Arctic really match with local community knowledge and interest? To answer this question and contribute to the ongoing debate on the missing connections between community needs and science perspective, the present study brings closer two different qualitative and quantitative approaches: an anthropolo...

What are the links between mainstream climate science and local community knowledge? This study takes the example of Greenland, considered one of the regions most impacted by climate change, and Inuit people, characterized as being highly adaptive to environmental change, to explore this question. The study is based on 10 years of anthropological p...

Description Fate and Impact of Microplastics in Marine Ecosystems: From the Coastline to the Open Sea brings together highlights from the conference proceedings for MICRO 2016: Fate and Impact of Microplastics in Marine Ecosystems: From the Coastline to the Open Sea. While the presence of microplastics in ecosystems has been reported in the scien...

Just as teachers strive to inspire a dedication to lifelong learning in their students, educators must also continue their own learning as professionals in order to keep pace with a changing world through updates in curriculum content and pedagogical practices. In Spain, Continuous Teacher Training (CTT) programs are in place to support teachers' i...

As the rate of plastic production increases globally, we see the problem of plastic debris in oceans and coastal zones also increasing, even in areas under rigorous environmental protection. Drawing from a case study situated within the UNESCO Biosphere Reserve of Lanzarote in the Canary Islands, this chapter shares the example of an ongoing, colla...

Rapid changes are an integral part of what defines the dynamic nature of coastal systems. Yet the twenty-first century will be increasingly characterized by an even greater pace of change. In this chapter we argue that, in order to face this acceleration, one needs to transcend the traditional organization of science. We further argue that this tra...

Coastal Zones: Solutions for the 21st Century bridges the gap between national and international efforts and the local needs for actions in communities where coastal zone challenges are faced daily. The solution-oriented approach covers issues of coastal zone management as well as responses to natural disasters. This work provides ideas on how to f...

Coastal zones and the biosphere as a whole show signs of cumulative degradation due to the use and disposal of plastics. To better understand the manifestation of plastic pollution in the Atlantic Ocean, we partnered with local communities to determine the concentrations of micro-plastics in 125 beaches on three islands in the Canary Current: Lanza...

Though the late Miocene “Messinian Salinity Crisis” has been intensely researched along the circum-Mediterranean basins, few studies have focused on the central part of the Mediterranean Basin and, especially, the pre-salt deposits. To improve our knowledge of the Messinian events, it is imperative to better understand this domain. In this study, w...

The Gulf of Lion margin has been created by an Oligo-Aquitanian rifting followed by oceanic accretion in the Provencal basin during the Burdigalian. Two main periods have been detailed in this study. The Messinian event represents a clear marker (between 7 and 5.3 Ma) within the history of the basin. The study of sedimentary geometries on the margi...

The Messinian erosional surface that can be observed on the Mediterranean margins is a good marker of the relative lowering of the sea level which happened during the Messinian salinity crisis. The estimate of the volume of Miocene sediments on the Gulf of Lion platform gives a minimum eroded volume of 5 300 Km . The eroded layer reaches one kilome...

A detailed morphological analysis of the outer shelf and continental slope of the Western Gulf of Lion is presented, based on swath bathymetry data together with sub-bottom profiles and high resolution seismic reflection profiles. These data reveal two main erosive features, of very different dimensions: the axial incision and the canyon's major va...

The continental margin of the Golfe du Lion was deeply eroded during the Messinain drawdown of the western Mediterranean Sea, and has subsequently been rebuilt by sediments supplied by the Rhone and adjacent rivers. We are engaged in a study of the evolution of this margin based on sequential backstripping, which accounts for the several processes...

A detailed morphological analysis of the submarine canyons in the Western Gulf of Lions shows the widespread occurrence of an axial incision excavated within the main valley. Such an incision is interpreted as a relict feature dating from the Last Glacial Maximum when sediment transfer from river mouths to canyon heads was enhanced due to sea level...

Submarine canyons are the preferential path of sediment transfer from the shelf to the deep sea, they are the key to understand the source-to-sink sedimentation and, in consequence, the shelf, slope and rise evolution. Pioneer works on submarine canyons described and proposed hypothesis to explain the formation and evolution of them. However, subma...

Promess 1 was the first scientific drilling operation in the Gulf of Lions. Together with Eurostrataform, these 2 European projects provided a huge amount of new data that allows us to analyse, from « sink to source », the main processes that control strata architecture on a deltaic margin. In the deep-sea, The Rhone deep sea fan functioning is str...
