- Traditional impact models combine exposure in the form of scenarios and sensitivity in the form of parameters, providing potential impacts of global change as model outputs. However, adaptive capacity is rarely addressed in these models. This paper presents the first spatially explicit scenario-driven model of adaptive capacity, which can be combined with impact models to support quantitative vulnerability assessment. The adaptive capacity model is based on twelve socio-economic indicators, each of which is projected into the future using four global environmental change scenarios, and then aggregated into an adaptive capacity index in a stepwise approach using fuzzy set theory. The adaptive capacity model provides insight into broad patterns of adaptive capacity across Europe, the relative importance of the various determinants of adaptive capacity, and how adaptive capacity changes over time under different social and economic assumptions. As such it provides a context for the implementation of specific adaptation measures. This could improve integrated assessment models and could be extended to other regions. However, there is a clear need for a better theoretical understanding of the adaptive capacity concept, and its relationship to the actual implementation of adaptation measures. This requires more empirical research and coordinated meta-analyses across regions and economic sectors, and the development of bottom-up modelling techniques that can incorporate human decision making.

- Achieving sustainable development as an inclusive societal process in rural landscapes, and sustainability in terms of functional green infrastructures for biodiversity conservation and ecosystem services, are wicked challenges. Competing claims from various sectors call for evidence-based adaptive collaborative governance. Leveraging such approaches requires maintenance of several forms of social interactions and capitals. Focusing on Pan-European regions with different environmental histories and cultures, we estimate the state and trends of two groups of factors underpinning rural landscape stewardship, namely, (1) traditional rural landscape and novel face-to-face as well as virtual fora for social interaction, and (2) bonding, bridging, and linking forms of social capital. We applied horizon scanning to 16 local landscapes located in 18 countries, representing Pan-European social-ecological and cultural gradients. The resulting narratives, and rapid appraisal knowledge, were used to estimate portfolios of different fora for social interactions and forms of social capital supporting landscape stewardship. The portfolios of fora for social interactions were linked to societal cultures across the European continent: "self-expression and secular-rational values" in the northwest, "Catholic" in the south, and "survival and traditional authority values" in the East. This was explained by the role of traditional secular and religious local meeting places. Virtual internet-based fora were most widespread. Bonding social capitals were the strongest across the case study landscapes, and linking social capitals were the weakest. This applied to all three groups of fora. Pan-European social-ecological contexts can be divided into distinct clusters with respect to the portfolios of different fora supporting landscape stewardship, which draw mostly on bonding and bridging forms of social capital. This emphasizes the need for regionally and culturally adapted approaches to landscape stewardship, which are underpinned by evidence-based knowledge about how to sustain green infrastructures based on both forest naturalness and cultural landscape values. Sharing knowledge from comparative studies can strengthen linking social capital.

- With climate change, coastal areas are faced with unprecedented sea level rise and flooding, raising questions as to how societies will choose to adapt. One option is to strengthen existing sea walls to maintain current land uses; however, scientists, policy-makers and conservationists increasingly see the benefits of managed realignment, which is a nature-based coastal adaptation that involves the conversion of reclaimed farmland back to wetlands, allowing periodic local flooding in designated areas to reduce the risk of flooding downstream. We interviewed 16 local organisations, landowners and farmers and held workshops with 109 citizens living the Inner Forth estuary in eastern Scotland, to examine how managed realignment is supported by stakeholder attitudes and their engagement. Most of the farmers we interviewed prefer strengthened sea walls, to maintain their livelihoods and agricultural heritage. Citizens and local organisations were mainly supportive of managed realignment, because it provided wildlife and flood regulation benefits. However, we identified several barriers that could present obstacles to implementing managed realignment, for example, uncertainty whether it would support their principles of economic and rational decision-making. Our findings suggest that the local capacity to cope with rising sea levels is limited by lack of engagement with all relevant stakeholder groups, the limited scope of existing stakeholder partnerships and poor short-term funding prospects of landscape partnerships that would facilitate collaboration and discussion. We suggest that including citizens, landowners, farmers and industries would strengthen existing stakeholder deliberation and collaboration, and support the Inner Forth’s transition towards a more sustainable future shoreline.

- Pavlovian biases influence instrumental learning by coupling reward seeking with action invigoration and punishment avoidance with action suppression. Using a probabilistic go/no-go task designed to orthogonalize action (go/no-go) and valence (reward/punishment), recent studies have shown that the interaction between the two is dependent on the striatum and its key neuromodulator dopamine. Using this task, we sought to identify how structural and neuromodulatory age-related differences in the striatum may influence Pavlovian biases and instrumental learning in 25 young and 31 older adults. Computational modeling revealed a significant age-related reduction in reward and punishment sensitivity and marked (albeit not significant) reduction in learning rate and lapse rate (irreducible noise). Voxel-based morphometry analysis using 7 Tesla MRI images showed that individual differences in learning rate in older adults were related to the volume of the caudate nucleus. In contrast, dopamine synthesis capacity in the dorsal striatum, assessed using [F-18]-DOPA positron emission tomography in 22 of these older adults, was not associated with learning performance and did not moderate the relationship between caudate volume and learning rate. This multiparametric approach suggests that age-related differences in striatal volume may influence learning proficiency in old age.

Creating space, aligning motivations, and building trust: a practical framework for stakeholder engagement based on experience in 12 ecosystem services case studies
- 2019

Tidskriftsartikel (refereegranskat)abstract
- Ecosystem services inherently involve people, whose values help define the benefits of nature's services. It is thus important for researchers to involve stakeholders in ecosystem services research. However, a simple and practicable framework to guide such engagement, and in particular to help researchers anticipate and consider key issues and challenges, has not been well explored. Here, we use experience from the 12 case studies in the European Operational Potential of Ecosystem Research Applications (OPERAs) project to propose a stakeholder engagement framework comprising three key elements: creating space, aligning motivations, and building trust. We argue that involving stakeholders in research demands thoughtful reflection from the researchers about what kind of space they want to create, including if and how they want to bring different interests together, how much space they want to allow for critical discussion, and whether there is a role for particular stakeholders to serve as conduits between others. In addition, understanding their own motivations—including values, knowledge, goals, and desired benefits—will help researchers decide when and how to involve stakeholders, identify areas of common ground and potential disagreement, frame the project appropriately, set expectations, and ensure each party is able to see benefits of engaging with each other. Finally, building relationships with stakeholders can be difficult but considering the roles of existing relationships, time, approach, reputation, and belonging can help build mutual trust. Although the three key elements and the paths between them can play out differently depending on the particular research project, we suggest that a research design that considers how to create the space in which researchers and stakeholders will meet, align motivations between researchers and stakeholders, and build mutual trust will help foster productive researcher–stakeholder relationships.

- The STRAP (Synergie Transdisciplinaire pour Répondre aux Aléas liés aux Panaches volcaniques) campaign was conducted in 2015 to investigate the volcanic plumes of Piton de La Fournaise (La Réunion, France). For the first time, measurements at the local (near the vent) and at the regional scales around the island were conducted. The STRAP 2015 campaign has become possible thanks to a strong cross-disciplinary collaboration between volcanologists and meteorologists. The main observations during four eruptive periods (85 days) are summarized. They include the estimates of SO2, CO2 and H2O emissions, the altitude of the plume at the vent and over different areas of La Réunion Island, the evolution of the SO2 concentration, the aerosol size distribution, and the aerosol extinction profile. A climatology of the volcanic plume dispersion is also reported. Simulations and measurements showed that the plume formed by weak eruption has a stronger interaction with the surface of the island. Strong SO2 and particles concentrations above 1000 ppb and 50 000 cm−3, respectively, are frequently measured over 20 km of distance from the Piton de la Fournaise. The measured aerosol size distribution shows the predominance of small particles in the volcanic plume. A particular emphasis is placed on the gas-particle conversion with several cases of strong nucleation of sulfuric acid observed within the plume and at the distal site of the Maïdo observatory. The STRAP 2015 campaign gave a unique set of multi-disciplinary data that can now be used by modellers to improve the numerical paramameterizations of the physical and chemical evolution of the volcanic plumes.

- Anthropogenic climate change calls for rapid and enormous cuts in emissions of CO2 and other greenhouse gases to mitigate future impacts. Even with these, however, many changes will continue to occur over the next 20-30 years adding to those already observed. Adaptation is crucial and urgent, but identifying strategies is complex and requires dialogue and cooperation among stakeholders, especially for infrastructure that exhibits interdependent risks in that failure in one type may impact others. A serious game was codeveloped with infrastructure operators to communicate climate projections and climate hazards to them; identify potential interdependencies, cascading impacts, cumulative effects, and vulnerability hot spots; and engage them to improve cooperation and enable a shared understanding of cross-cutting climate risks and interdependencies. In the game, players provide present-day infrastructure services in the Inverclyde district, Scotland, as they experience a plausible decade of 2050s weather characterized by a sequence of hazard events. This sequence was extracted from climate model projections to ensure scientific plausibility. The infrastructure operators were responsible for drinking water and gas supplies, road and rail transport, wastewater treatment, and civil infrastructure. When playing the game the participating U.K. infrastructure providers felt that although there were challenges, they could cope with 2050s climate change. None of the projected hazard events were anticipated to cause catastrophic impact cascades on infrastructure. The game was positively received, and the study suggests it is a useful tool to both communicate climate hazards and explore potential interdependent risks by bringing together stakeholders' individual expertise in an engaging way.
