- ItemThe concerns of the young protesters are justified: A statement by Scientists for Future concerning the protests for more climate protection(München : Oekom Verl., 2019) Hagedorn, Gregor; Loew, Thomas; Seneviratne, Sonia I.; Lucht, Wolfgang; Beck, Marie-Luise; Hesse, Janina; Knutti, Reto; Quaschning, Volker; Schleimer, Jan-Hendrik; Mattauch, Linus; Breyer, Christian; Hübener, Heike; Kirchengast, Gottfried; Chodura, Alice; Clausen, Jens; Creutzig, Felix; Darbi, Marianne; Daub, Claus-Heinrich; Ekardt, Felix; Göpel, Maja; Hardt, Judith N.; Hertin, Julia; Hickler, Thomas; Köhncke, Arnulf; Köster, Stephan; Krohmer, Julia; Kromp-Kolb, Helga; Leinfelder, Reinhold; Mederake, Linda; Neuhaus, Michael; Rahmstorf, Stefan; Schmidt, Christine; Schneider, Christoph; Schneider, Gerhard; Seppelt, Ralf; Spindler, Uli; Springmann, Marco; Staab, Katharina; Stocker, Thomas F.; Steininger, Karl; Hirschhausen, Eckart von; Winter, Susanne; Wittau, Martin; Zens, JosefIn March 2019, German-speaking scientists and scholars calling themselves Scientists for Future, published a statement in support of the youth protesters in Germany, Austria, and Switzerland (Fridays for Future, Klimastreik/Climate Strike), verifying the scientific evidence that the youth protestors refer to. In this article, they provide the full text of the statement, including the list of supporting facts (in both English and German) as well as an analysis of the results and impacts of the statement. Furthermore, they reflect on the challenges for scientists and scholars who feel a dual responsibility: on the one hand, to remain independent and politically neutral, and, on the other hand, to inform and warn societies of the dangers that lie ahead. © 2019 G.

- ItemSynthesizing plausible futures for biodiversity and ecosystem services in europe and central asia using scenario archetypes(Wolfville, Nova Scotia : Resilience Alliance, 2019) Harrison, Paula A.; Harmáčková, Zuzana V.; Karabulut, Armağan Aloe; Brotons, Lluis; Cantele, Matthew; Claudet, Joachim; Dunford, Robert W.; Guisan, Antoine; Holman, Ian P.; Jacobs, Sander; Kok, Kasper; Lobanova, Anastasia; Morán-Ordóñez, Alejandra; Pedde, Simona; Rixen, Christian; Santos-Martín, Fernando; Schlaepfer, Martin A.; Solidoro, Cosimo; Sonrel, Anthony; Hauck, JenniferScenarios are a useful tool to explore possible futures of social-ecological systems. The number of scenarios has increased dramatically over recent decades, with a large diversity in temporal and spatial scales, purposes, themes, development methods, and content. Scenario archetypes generically describe future developments and can be useful in meaningfully classifying scenarios, structuring and summarizing the overwhelming amount of information, and enabling scientific outputs to more effectively interface with decision-making frameworks. The Intergovernmental Platform for Biodiversity and Ecosystem Services (IPBES) faced this challenge and used scenario archetypes in its assessment of future interactions between nature and society. We describe the use of scenario archetypes in the IPBES Regional Assessment of Europe and Central Asia. Six scenario archetypes for the region are described in terms of their driver assumptions and impacts on nature (including biodiversity) and its contributions to people (including ecosystem services): Business-as-usual, economic optimism, regional competition, regional sustainability, global sustainable development, and inequality. The analysis shows that trade-offs between nature’s contributions to people are projected under different scenario archetypes. However, the means of resolving these trade-offs depend on differing political and societal value judgements within each scenario archetype. Scenarios that include proactive decision making on environmental issues, environmental management approaches that support multifunctionality, and mainstreaming environmental issues across sectors, are generally more successful in mitigating tradeoffs than isolated environmental policies. Furthermore, those scenario archetypes that focus on achieving a balanced supply of nature’s contributions to people and that incorporate a diversity of values are estimated to achieve more policy goals and targets, such as the UN Sustainable Development Goals and the Convention on Biological Diversity Aichi targets. The scenario archetypes approach is shown to be helpful in supporting science-policy dialogue for proactive decision making that anticipates change, mitigates undesirable trade-offs, and fosters societal transformation in pursuit of sustainable development. © 2019 by the author(s).
- ItemChallenges in producing policy-relevant global scenarios of biodiversity and ecosystem services(Amsterdam : Elsevier, 2020) Rosa, Isabel M.D.; Purvis, Andy; Alkemade, Rob; Chaplin-Kramer, Rebecca; Ferrier, Simon; Guerra, Carlos A.; Hurtt, George; Kim, HyeJin; Leadley, Paul; Martins, Inês S.; Popp, Alexander; Schipper, Aafke M.; van Vuuren, Detlef; Pereira, Henrique M.Scenario-based modelling is a powerful tool to describe relationships between plausible trajectories of drivers, possible policy interventions, and impacts on biodiversity and ecosystem services. Model inter-comparisons are key in quantifying uncertainties and identifying avenues for model improvement but have been missing among the global biodiversity and ecosystem services modelling communities. The biodiversity and ecosystem services scenario-based inter-model comparison (BES-SIM) aims to fill this gap. We used global land-use and climate projections to simulate possible future impacts on terrestrial biodiversity and ecosystem services using a variety of models and a range of harmonized metrics. The goal of this paper is to reflect on the steps taken in BES-SIM, identify remaining methodological challenges, and suggest pathways for improvement. We identified five major groups of challenges; the need to: 1) better account for the role of nature in future human development storylines; 2) improve the representation of drivers in the scenarios by increasing the resolution (temporal, spatial and thematic) of land-use as key driver of biodiversity change and including additional relevant drivers; 3) explicitly integrate species- and trait-level biodiversity in ecosystem services models; 4) expand the coverage of the multiple dimensions of biodiversity and ecosystem services; and finally, 5) incorporate time-series or one-off historical data in the calibration and validation of biodiversity and ecosystem services models. Addressing these challenges would allow the development of more integrated global projections of biodiversity and ecosystem services, thereby improving their policy relevance in supporting the interlinked international conservation and sustainable development agendas. © 2019 The Authors
