Beschreibung: This assessment report identifies six key areas of sustainable consumption. Transforming those areas is associated with a significant, positive impact on sustainable development. In this way, those key areas lay the foundation to set clear priorities and formulate concrete policy measures and recommendations. The report describes recent developments and relevant actors in those six fields, outlines drivers and barriers to reach a shift towards more sustainability in those specific areas, and explores international good-practice examples. On top of this, overarching topics in the scientific discourse concerning sustainable consumption (e.g. collaborative economy, behavioural economics and nudging) are revealed by using innovative text-mining techniques. Subsequently, the report outlines the contributions of these research approaches to transforming the key areas of sustainable consumption. Finally, the report derives policy recommendations to improve the German Sustainable Development Strategy (DNS) in order to achieve a stronger stimulus effect for sustainable consumption.

Beschreibung: Zum Austausch von Best Practices aus den Zentren und zur Förderung der FDM-Community in Helmholtz veranstaltete das Helmholtz Open Science Office am 3. Februar 2022 das erste „Helmholtz Open Science Praxisforum Forschungsdatenmanagement“. In dem Helmholtz-internen Forum wurden exemplarisch verschiedene Herangehensweisen aus Zentren zur Organisation des FDM vorgestellt. Darüber hinaus standen konkrete Service-Angebote zu FDM im Mittelpunkt. Außerdem wurde die Vernetzung mit externen Akteuren, z. B. im Rahmen der NFDI, EOSC oder der RDA, beleuchtet. Die regen Diskussionen verdeutlichten den hohen Bedarf nach übergreifendem Community-Building im Bereich des FDM innerhalb von Helmholtz und darüber hinaus.

Beschreibung: The spatial and temporal heterogeneity of ecosystems plays an important role in species distribution and ecosystem dynamics (Kovalenko et al., 2012). The physical and biochemical properties of the waters of the Mackenzie Shelf in the Beaufort Sea are strongly influenced by the eponymous river and its discharge plume, occasionally causing strong salinity, temperature, and turbidity gradients (Brenkman et al., 2007; Swanson & Kidd, 2009; Jensen et al., 2014), thus affecting the distribution of economically and culturally important organisms, among others. Clarifying how the physical characteristics of marine habitats influence the relative abundance and demographic characteristics of anadromous fishes has an important bearing on management and conservation objectives. The objective of this study was to examine how the timing and catch of Dolly Varden in the nearshore summer subsistence fishery are affected by environmental conditions in the Beaufort Sea. In addition, we examined whether there is a relationship between environmental parameters and the demographic and somatic characteristics of the Dolly Varden caught. The study analysed fisheries-dependent data from two different study sites (Herschel Island and Shingle Point, Yukon Territory, Canada) from 2013 to 2019. Remotely sensed environmental parameters of temperature, chlorophyll-a, turbidity, and sea ice were derived from Landsat-8 and Sentinel-2 imagery and examined along with wind vectors. To provide information on how Dolly Varden abundances respond to stochastic environmental events in marine waters. Measured environmental parameters show that aggregation of Dolly Varden on Herschel Island is spatially correlated with increased chlorophyll-a as well as SST. Stochastic turbidity events showed a negative influence, causing specimens to seek spatial refuge in better water conditions. Results showed similar correlations for SPT, although the parameters here are much more difficult to differentiate due to the high suspended sediment concentration (CDOM). Data obtained from this study indicate that the geographic distribution of Dolly Varden in the Beaufort Sea is dependent on condition and osmoregulation (age/length). In marine waters, adult individuals are clearly influenced by stochastic environmental events (temperature and turbidity), opportunistically seeking out production hotspots for feeding (sea ice and chlorophyll-a).

Beschreibung: Digitalisation is taking place at a fast pace in all European countries and it is transforming the economies, societies, communication, jobs and the necessary skills for the workplace and everyday life. The Covid-19 pandemic is also accelerating digitalisation at many levels. To address the great challenges resulting from this, the European Commission has launched the Green Deal, a long-term transformation strategy towards an innovative and sustainable society. Three important initiatives under the Green Deal are the New Circular Economy Action Plan, the Biodiversity Strategy for 2030 and the Zero Pollution Action Plan. The various strategies and action plans draw up a large portfolio of measures, instruments and milestones that are always linked to digital technologies. Ideally, these are eco-innovative and sustainable and contribute to improving living conditions in Europe. The EIO Biennial Report 2020, which looks at a different topic every two years, considers digitalisation a major opportunity to accelerate the transition to a circular Europe. In the current report, the authors provide an overview of eco-innovation trends, illustrated by digital technology and policy practices that can further drive the circular economy.

Beschreibung: SeaDataCloud Temperature and Salinity historical data collections covering the time period 1900-2018 were released in 2020 for each European marginal sea (Arctic Sea, Baltic Sea, Black Sea, North Sea, North Atlantic Ocean, and Mediterranean Sea). A Quality Assurance Strategy (QAS) was developed and continuously refined in order to improve the quality of the SeaDataNet database content and derive the best data products through an iterative approach, which allows the versioning of data products. Regional Temperature and Salinity climatologies (see Figure 1) have been produced using DIVAnd software (Barth et al. 2014) and integrating for the first time SeaDataNet data with external data sources, such as CMEMS in situ TAC (Coriolis Ocean Dataset for Reanalysis) that highly increased the temporal and spatial data coverage. Regional climatologies were designed with a harmonized initial approach and all cover the time period after 1955, when marine data start to be sufficient for mapping. All regional products are characterized by monthly fields over the whole time span 1955-2018 and seasonal decadal fields on the same vertical standard levels of the World Ocean Atlas (WOA18, Garcia et al., 2019). A global SDC climatology has been created for the first time, which contains two different monthly climatology for temperature and salinity, one covering the time period 1900-2017 and the other with a different time coverage 2003-2017, computed from World Ocean Database (WOD2018, Boyer et al., 2019). This choice has been made because spatial coverage of SeaDataNet data at global scale is still too sparse. A consistency analysis of all SDC climatologies versus the WOA has been performed to demonstrate the differences and the value added of SDC products. SDC team worked to optimize the data integration process with external sources, to better tune the DIVAnd parameters, the background field estimation and to improve the final consistency analysis with the available multi-year products from WOA and CMEMS. An overview of the methodology applied to compute the SDC climatologies and their main characteristics will be presented together with the main results achieved by the SDC products team. SDC products, data collections and climatologies, are available through a dedicated web catalogue (https://www.seadatanet.org/Products/) together with their Digital Object Identifier (DOI) and the relative Product Information Document (PIDoc), containing all specifications about product’s generation, quality assessment, technical details and usability to facilitate users’ uptake.

Beschreibung: The objective of this report is to use historical analysis to identify conditions that determine when offsets add value to compliance schemes while upholding environmental integrity. The indicators of success include: increased acceptance of introducing compliance schemes; raising ambition in subsequent compliance periods; the possibility to drive emission reductions outside the compliance sectors; promoting investments in sustainable development; and avoiding perverse incentives that undermine the stringency of the compliance scheme or compliance actors’ efforts in reducing their own emissions. Through undertaking in-depth case study analyzes on the effects of offsets in the European Union, Alberta, Australia, Colombia and Japan, the report identifies common conditions that explain why offsets were successful (or not) in achieving individual indicators. The report further identifies two common conditions that can help explain when offsets achieve all five indicators of success. The first is that policymakers need to be willing to design the compliance scheme to set and maintain a strong compliance price signal that justifies the need for incorporating cost containment measures, such as offsets, to avert negative political and economic ramifications. Relatedly, the second condition requires institutions, processes and infrastructure that govern both the compliance scheme and offsets to be well developed so that they can ensure offsets uphold the principles of environmental integrity, achieve sustainable development benefits, and act as a reliable cost containment measure to high compliance prices. The findings also highlight how difficult it is to achieve both conditions, as both domestic and international political economy factors determine whether policymakers and voters are willing to introduce and maintain compliance schemes that deliver effective action on climate.

Beschreibung: Effective actions to mitigate climate change are urgently needed, especially in the context of cities, which are major sources of global CO2 emissions. Establishing and managing knowledge systems that integrate local knowledge can contribute to establishing more effective responses to climate change as well as transformative change towards sustainability. However, it is still unclear how new forms of urban governance should acquire, store, create, or disseminate knowledge for fostering sustainability transitions effectively. In this study, we present a multilevel knowledge system approach based on design principles informed especially by the knowledge management literature. These address (i) working environments across multiple levels, (ii) knowledge forms and types, and (iii) knowledge processes. We apply this approach to municipal climate action in the German energy transition. In particular, we focus on the operational work of municipal climate action managers of regional centers of Lower Saxony, one of the largest of the 16 federal states, and investigate their involvement in knowledge processes. Based on semi-structured interviews in 14 of the 17 regional centers, we show that structural pre-conditions for successful knowledge management and organizational learning are present. However, we also show that there is a need for improvement regarding (i) the multilevel coordination for accelerating routine operation, (ii) the persistence of local operational knowledge, and (iii) the exploitation of local innovations. Relying on these results, we offer general recommendations for municipal climate action and suggest that policies should (i) rely on local knowledge for effective decision-making, (ii) foster multilevel exchanges of explicit and tacit knowledge for implementation, and (iii) enable open-ended learning processes that leverage local innovations for creating usable transformational knowledge.
