    Description: Global climate change affects marine fish through drivers such as ocean warming, acidification and oxygen depletion, causing changes in marine ecosystems and socioeconomic impacts. While experimental and observational results can inform about anticipated effects of different drivers, linking between these results and ecosystem-level changes requires quantitative integration of physiological and ecological processes into models to advance research and inform management. We give an overview of important physiological and ecological processes affected by environmental drivers. We then provide a review of available modelling approaches for marine fish, analysing their capacities for process-based integration of environmental drivers. Building on this, we propose approaches to advance important research questions. Examples of integration of environmental drivers exist for each model class. Recent extensions of modelling frameworks increase the potential for including detailed mechanisms and improving model projections. Experimental results on energy allocation, behaviour and physiological limitations will advance the understanding of organism-level trade-offs and thresholds in response to multiple drivers. More explicit representation of life cycles and biological traits can improve description of population dynamics and adaptation, and data on food web topology and feeding interactions help to detail the conditions for possible regime shifts. Identification of relevant processes will also benefit the coupling of different models to investigate spatial–temporal changes in stock productivity and integrated responses of social–ecological systems. Thus, a more process-informed foundation for models will promote the integration of experimental and observational results and increase the potential for model-based extrapolations into a future under changing environmental conditions.

    Environmental and trait variability constrain community structure and the biodiversity‐productivity relationship (2016)

    Description: There is still considerable debate about which mechanisms drive the relationship between biodiversity and ecosystem function (BEF). Although most scientists agree on the existence of two underlying mechanisms, complementarity and selection, experimental studies keep producing contrasting results on the relative contributions of the two effects. We present a spatially explicit resource competition model and investigate how the strength of these effects is influenced by trait and environmental variability, resource distribution, and species pool size. Our results demonstrate that the increase of biomass production with increasing species numbers depends on the concurrence of environmental and trait variability: BEF relationships are stronger if functionally different species coexist in a landscape with heterogeneous resource supply. These large biodiversity effects arise from complementarity effects, whereas selection effects are maximized when broad trait ranges coincide with narrow ranges of resource supply ratios. Our results will therefore help to resolve the debate on complementarity and selection mechanisms.

    Details
    Publication Date: 2022-02-18
    Description: In the context of the German-Korean Energy Policy Dialogue, integration of renewable power sources and smart grids have been identified as topics with high relevance. This study aims to support mutual learning and exploration of new fields for collaboration by identifying similarities and differences in the respective status quos, strategies and policies in both countries. After a short introduction to the South Korean energy situation, Chapter 2 provides an overview of the South Korean power market, its situation regarding renewable power sources and the Korean definition of smart grids. Chapter 3 of this study highlights the major South Korean energy strategies and regulatory frameworks relevant to integration of renewable energies and smart grids. In Chapter 4, the status and perspectives of renewable energy sources integration and smart grids in South Korea are discussed, presenting various demonstrative examples, new business models and the current situation of technology deployment. Chapter 5 puts South Korea in the global context and compares it to Germany. Finally, Chapter 6 draws conclusions and presents recommendations on suitable areas for mutual learning.

    What makes an ideal global stocktake? : A functional analysis ; discussion paper (2018)
    Dessau-Roßlau : Umweltbundesamt
    Details
    Publication Date: 2022-02-18
    Description: Many hope that the Global Stocktake under the Paris Agreement can become a catalyst for increased mitigation ambition over time. Based on different theories of change, this paper outlines four governance functions for the Global Stocktake. It can contribute to the Paris Agreement as a pacemaker (stimulating and synchronizing policy processes across governance levels), by ensuring accountability of Parties, by enhancing ambition through benchmarks for action and transformative learning, and by reiterating and refining the guidance and signal provided from the Paris Agreement. The paper further outlines process- and information-related preconditions that would enable an ideal Global Stocktake.

    Success factors for the global stocktake under the Paris Agreement (2019)
    Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie
    Details
    Publication Date: 2022-02-18
    Description: While the Paris Agreement (PA) has enshrined ambitious long-term objectives, the current level of action of the Parties to the Agreement falls far short of this ambition, as is recognised in the very COP decision adopting the Agreement. The Global Stocktake (GST) established in Art. 14 of the PA is a key element to address this problem. Its purpose is to review the implementation of the PA and to assess the progress made towards the collectively agreed goals. The aim of this report is to develop recommendations on how to maximise the potential impact of the GST. The report starts from a perspective of what the GST could ideally do, irrespective of decisions already taken under the UNFCCC and other political constraints. In the second step, the report takes these limitations into account and suggests ways for how to nonetheless work towards the desired outcome.

    Challenges of coal transitions : a comparative study on the status quo and future prospects of coal mining and coal use in Indonesia, Colombia and Viet Nam (2019)
    Dessau-Roßlau : Umweltbundesamt
    Details
    Publication Date: 2022-02-18
    Description: Today more than 45 % of all energy-related CO2 emissions come from burning coal. Thus, reducing CO2 emissions from coal use is a necessity for reaching the targets of the Paris Agreement. This will not only pose challenges for coal consumers (restructuring of the energy system), but also for countries whose economy is strongly depending on the production of coal. This paper examines the role of coal in three countries, which are or were in recent years among the top coal exporters: Indonesia, Colombia and Vietnam. Understanding challenges and possible transition pathways in these countries will help to develop global strategies to reduce CO2 emissions from coal in the short to mid-term.

    Socio-ecological innovations in the context of the German "Energiewende" : an analysis of benefits and necessities in the urban arena (2018)
    Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie
    Details
    Publication Date: 2022-11-10
    Description: Alternative power initiatives are socio-ecological innovations that substantially contribute to city's sustainable development and, therefore, are of particular societal benefit and value. Cities should, consequently, have an inherent interest in their existence and proliferation. This, however, asks for strategic innovation management. While, acknowledgement of the project's innovativeness constitutes the precondition for management, in the further process of steering activity the tasks to reduce hurdles, create open space and support the project's capacities need to be mastered. Thereby, cities are increasingly asked to become innovative themselves in order to find ways to optimally make use of their available tools and capacities.

    Fluid geographies: Marine territorialisation and the scaling up of local aquatic epistemologies on the Pacific coast of Colombia (2018)
    Wiley
    In:  EPIC3Transactions of the Institute of British Geographers, Wiley, 43(1), pp. 61-78, ISSN: 0020-2754

    Description: The Pacific region of Colombia, like many sparsely populated places in developing countries, has been imagined as empty in social terms, and yet full in terms of natural resources and biodiversity. These imaginaries have enabled the creation of frontiers of land and sea control, where the state as well as private and illegal actors have historically dispossessed Afro-descendant and indigenous peoples. This paper contributes to the understanding of territorialisation in the oceans, where political and legal framings of the sea as an open-access public good have neglected the existence of marine social processes. It shows how Afro-descendant communities and non-state actors are required to use the language of resources, rather than socio-cultural attachment, to negotiate state marine territorialisation processes. Drawing on a case study on the Pacific coast of Colombia, we demonstrate that Afro-descendant communities hold local aquatic epistemologies, in which knowledge and the production of space are entangled in fluid and volumetric spatio-temporal dynamics. However, despite the social importance of aquatic environments, they were excluded from Afro-descendants' collective territorial rights in the 1990s. Driven by their local aquatic epistemologies, coastal communities are reclaiming authority over the seascape through the creation of a marine protected area. We argue that they have transformed relations of authority at sea to ensure local access and control, using state institutional instruments to subvert and challenge the legal framing of the sea as an open access public good. As such, this marine protected area represents a place of resistance that ironically subjects coastal communities to disciplinary technologies of conservation.
