    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.

    The Climatic Response of Tree Ring Width Components of Ash (Fraxinus excelsior L.) and Common Oak (Quercus robur L.) from Eastern Europe (2020)
    MDPI
    In:  EPIC3Forests, MDPI, 11(5), ISSN: 1999-4907
    Details
    Publication Date: 2020-08-10
    Description: This paper aims to develop the first differentiated (earlywood—EW, latewood—LW, and total ring width—RW) dendrochronological series for ash (Fraxinus excelsior L.) and oak (Quercus robur L.) trees from the Republic of Moldova, and to analyze their climatic response and their spatio-temporal stability. For this, 18 ash and 26 oak trees were cored from the DobruÈ�a protected area, Republic of Moldova, Eastern Europe, and new EW, LW, and RW chronologies were developed for ash and oak covering the last century. The obtained results showed that the RW and LW have a similar climatic response for both species, while EW is capturing interannual climate variations and has a different reaction. The analyses performed with monthly climatic data revealed a significant and negative correlation with the mean air temperature and a significant and positive correlation with precipitation and the Standardized Precipitation-Evapotranspiration Index (SPEI) for both ash and oak. The temperature during the vegetation period has a strong influence on all tree-ring components of ash, while for oak the strong correlation was found only for LW. The positive and significant correlation between LW and RW with precipitation for both species, suggests that ash and oak are sensitive to the hydrological component and the precipitation is the main tree growth-limiting factor. Despite the significant correlation with precipitation and temperature for the whole analyzed period, the 25-year moving correlation analyses show that they are not stable in time and can switch from positive to negative or vice versa, while the correlation with SPEI3 drought index, which is a integration of both climatic parameters, is stable in time. By employing the stability map analysis, we show that oak and ash tree ring components, from the eastern part of the Republic of Moldova, have a stable and significant correlation with SPEI3 and scPDSI drought indices from February (January) until September, over the eastern part of Europe.

    Diversity of Bacterioplankton and Bacteriobenthos from the Veracruz Reef System, Southwestern Gulf of Mexico (2021)
    MDPI
    In:  EPIC3Microorganisms, MDPI, 9(3), pp. 619, ISSN: 2076-2607
    Details
    Publication Date: 2021-03-19
    Description: Bacterial diversity was explored among field samples and cultured isolates from coral reefs within the Veracruz Reef System. Bacterioplankton and bacteriobenthos were characterized by pyrosequencing 16S rRNA genes. Identified sequences belonged to the kingdom Bacteria and classified into 33 phyla. Proteobacteria (likely SAR11 clade) dominated in collective field samples, whereas Firmicutes were the most abundant taxa among cultured isolates. Bioinformatic sorting of sequences to family level revealed 223 bacterial families. Pseudomonadaceae, Exiguobacteraceae and Bacillaceae were dominant among cultured isolates. Vibrionaceae, Alteromonadaceae, and Flavobacteriaceae dominated in reef-associated sediments, whereas Rickettsiaceae and Synechoccaceae were more highly represented in the water column. Bacterial communities from sediments were more diverse than from the water column. This study reveals cryptic bacterial diversity among microenvironmental components of marine microbial reef communities subject to differential influence of anthropogenic stressors. Such investigations are critical for constructing scenarios of environmentally induced shifts in bacterial biodiversity and species composition.

    Ensemble Mapping and Change Analysis of the Seafloor Sediment Distribution in the Sylt Outer Reef, German North Sea from 2016 to 2018 (2021)
    MDPI
    In:  EPIC3Water, MDPI, 13(16), pp. 2254, ISSN: 2073-4441
    Details
    Publication Date: 2021-08-24
    Description: Recent studies on seafloor mapping have presented different modelling methods for the automatic classification of seafloor sediments. However, most of these studies have applied these models to seafloor data with appropriate numbers of ground-truth samples and without consideration of the imbalances in the ground-truth datasets. In this study, we aim to address these issues by conducting class-specific predictions using ensemble modelling to map seafloor sediment distributions with minimal ground-truth data combined with hydroacoustic datasets. The resulting class-specific maps were then assembled into a sediment classification map, in which the most probable class was assigned to the appropriate location. Our approach was able to predict sediment classes without bias to the class with more ground-truth data and produced reliable seafloor sediment distributions maps that can be used for seafloor monitoring. The methods presented can also be used for other underwater exploration studies with minimal ground-truth data. Sediment shifts of a heterogenous seafloor in the Sylt Outer Reef, German North Sea were also assessed to understand the sediment dynamics in the marine conservation area during two different short timescales: 2016–2018 (17 months) and 2018–2019 (4 months). The analyses of the sediment shifts showed that the western area of the Sylt Outer Reef experienced sediment fluctuations but the morphology of the bedform features was relatively stable. The results provided information on the seafloor dynamics, which can assist in the management of the marine conservation area.

    Challenges in the Paleoclimatic Evolution of the Arctic and Subarctic Pacific since the Last Glacial Period — the Sino-German Pacific – Arctic Experiment (SiGePAX) (2019)
    MDPI
    In:  EPIC3Challenges, MDPI, 10(1), pp. 1-22, ISSN: 2078-1547

    Description: Arctic and subarctic regions are sensitive to climate change and, reversely, provide dramatic feedbacks to the global climate. With a focus on discovering paleoclimate and paleoceanographic evolution in the Arctic and Northwest Pacific Oceans during the last 20,000 years, we proposed this German–Sino cooperation program according to the announcement “Federal Ministry of Education and Research (BMBF) of the Federal Republic of Germany for a German–Sino cooperation program in the marine and polar research”. Our proposed program integrates the advantages of the Arctic and Subarctic marine sediment studies in AWI (Alfred Wegener Institute) and FIO (First Institute of Oceanography). For the first time, the collection of sediment cores can cover all climatological key regions in the Arctic and Northwest Pacific Oceans. Furthermore, the climate modeling work at AWI enables a “Data-Model Syntheses”, which are crucial for exploring the underlying mechanisms of observed changes in proxy records.
