    MyEcoCost - forming the nucleus of a novel environmental accounting system : vision, prototype and way forward (2015)
    Wuppertal : Wuppertal Institute for Climate, Environment and Energy
    Details
    Publication Date: 2022-11-10
    Description: The innovative software system "myEcoCost" enables to gather and communicate resource and environmental data for products and services in global value chains. The system has been developed in the consortium of the European research project myEcoCost and forms a basis of a new, highly automated environmental accounting system für companies and consumers. The prototype of the system, linked to financial accounting of companies, was developed and tested in close collaboration with large and small companies. This brochure gives a brief introduction to the vision linked to myEcoCost: a network formed by collaborative environmental accounting nodes collecting environmental data at each step in a product's value chains. It shows why better life cycle data are needed and how myEcoCost addresses and solves this problem. Furthermore, it presents options for a future upscaling of highly automated environmenal accounting for prodcuts and services.

    Pledge for a transformative science : a conceptual framework (2016)
    Wuppertal : Wuppertal Institute for Climate, Environment and Energy
    Details
    Publication Date: 2022-11-10
    Description: "Transformative science" is a concept that delineates the new role of science for knowledge societies in the age of reflexive modernity. The paper develops the program of a transformative science, which goes beyond observing and analyzing societal transformations, but rather takes an active role in initiating and catalyzing change processes. The aim of transformative science is to achieve a deeper understanding of ongoing transformations and increased societal capacity for reflexivity with regard to these fundamental change processes. The concept of transformative science is grounded in an experimental paradigm, which has implications for (1) research, (2) education and learning, and (3) institutional structures and change in the science system. The article develops the theoretical foundations of the concept of transformative science and spells out the concrete implications in these three dimensions.

    Article 6 and the global stocktake (2018)
    Wuppertal : Wuppertal Institute for Climate, Environment and Energy
    Details
    Publication Date: 2019-01-31
    Description: Although it is not part of what has been called the "ambition mechanism" or "ratchet mechanism", Article 6 of the Paris Agreement also has an explicit requirement to promote ambition. Article 6 specifically highlights that some Parties choose to pursue voluntary cooperation in the implementation of their nationally determined contributions to allow for higher ambition in their mitigation and adaptation actions. Despite the common purpose, the two elements have to date been discussed mostly in isolation, both in the negotiations as well as in the wider literature. This JIKO Policy Paper sets out to change this by exploring the relationship between Article 6 and the Global Stocktake.

    Additionality après Paris : stronghold for environmental integrity? (2018)
    Wuppertal : Wuppertal Institute for Climate, Environment and Energy
    Details
    Publication Date: 2021-04-20
    Description: This policy paper reviews the concept of additionality in the context of the Paris Agreement. Additionality is a key criterion that helps to maintain the environmental integrity of the Paris Agreement, especially when units created under Article 6.2 or 6.4 are used for offsetting purposes whether that is by Parties in order to meet their NDCs or whether by other entities with legal mitigation obligations. It does so by first reviewing key concepts such as offsetting, environmental integrity, and baseline. Subsequently, it explores the context of additionality under the Paris Agreement. More specifically it discusses what should be counted as the baseline for additionality demonstration. The subsequent chapter then highlights the challenges with establishing additionality, that is establishing a causal relationship between a policy intervention and a proposed activity. Finally, the Policy Paper discusses aspects of international governance with respect to additionality.

    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.

    Unknown Extracellular and Bioactive Metabolites of the Genus Alexandrium: A Review of Overlooked Toxins (2021)
    MDPI
    In:  EPIC3Toxins, MDPI, 13, pp. 905, ISSN: 2072-6651
    Details
    Publication Date: 2021-12-22
    Description: Various species of Alexandrium can produce a number of bioactive compounds, e.g., paralytic shellfish toxins (PSTs), spirolides, gymnodimines, goniodomins, and also uncharacterised bioactive extracellular compounds (BECs). The latter metabolites are released into the environment and affect a large range of organisms (from protists to fishes and mammalian cell lines). These compounds mediate allelochemical interactions, have anti-grazing and anti-parasitic activities, and have a potentially strong structuring role for the dynamic of Alexandrium blooms. In many studies evaluating the effects of Alexandrium on marine organisms, only the classical toxins were reported and the involvement of BECs was not considered. A lack of information on the presence/absence of BECs in experimental strains is likely the cause of contrasting results in the literature that render impossible a distinction between PSTs and BECs effects. We review the knowledge on Alexandrium BEC, (i.e., producing species, target cells, physiological effects, detection methods and molecular candidates). Overall, we highlight the need to identify the nature of Alexandrium BECs and urge further research on the chemical interactions according to their ecological importance in the planktonic chemical warfare and due to their potential collateral damage to a wide range of organisms.
