    Urban environmental protection international : stock-taking and outlook ; final report (2021)
    Dessau-Roßlau : Umweltbundesamt
    Details
    Publication Date: 2022-02-18
    Description: The aim of this study is to contribute to a learning process about innovative and successful approaches to overcoming problems and challenges of urban environmental protection. To this end, a detailed overview of the importance of environmental challenges, political priorities and successful solutions in selected countries and cities is given. Based on this, the study analyzes specific success factors and discusses the extent to which these can be transferred and replicated to other cities. Finally, recommendations are made for cities, countries and the international community on how environmental protection at the urban level can be further strengthened. The role of German cities and institutions will also be discussed. The case studies analyzed include Belo Horizonte in Brazil, Moscow in Russia, Kochi in India, Beijing in China, Cape Town in South Africa and Jakarta in Indonesia. These cities were selected because they have already implemented successful policies, measures and other initiatives in the past. For each city, the study analyzes relevant policy documents in order to present the respective challenges and political priorities. The analysis aims to understand the effectiveness of the plans and instruments taking into account the national political environment. Despite the cross-sectoral approach, the analysis of each case study focuses on specific sectors in order to produce well-founded results. The success factors that are worked out based on this sectoral analysis are placed in a holistic context in order to be able to make generalizable statements about success factors.

    Offset approaches in existing compliance mechanisms : adding value and upholding environmental integrity? (2022)
    Dessau-Roßlau : Umweltbundesamt
    Details
    Publication Date: 2022-08-15
    Description: 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.

    The challenges of assessing "collective progress" : design options for an effective global stocktake process under the UNFCCC ; final report (2021)
    Dessau-Roßlau : Umweltbundesamt
    Details
    Publication Date: 2022-02-18
    Description: The Paris Agreement combines collective goals with individual countries' contributions. This hybrid approach does not guarantee that the individual contributions add up to what is required to meet the collective goals. The Paris Agreement therefore established the Global Stocktake. Its task is to "assess collective progress" towards achieving the long-term goals of the agreement as of 2023 and every five years thereafter. Corresponding to this role, this report addresses three questions: What should an effective Global Stocktake look like? What information and data are needed? Is it possible to execute an effective Global Stocktake within the mandate of the Paris Agreement?

    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.

    Substantive implementation of article 29 of directive 2008/98/EC : scientific-technical foundation for a national waste prevention programme (2013)
    Dessau-Roßlau : Umweltbundesamt
    Details
    Publication Date: 2022-02-18
    Description: Based on the European Waste Framework Directive and the German Recycling Management Act of 01.06.2012 the objectives for a national waste prevention programme were defined. As main objective, according to art. 1 WFD, the "prevention or reduction of the disadvantageous impacts of waste generation and management on the human health and the environment" is recommended. Indicators for a quantitative and qualitative monitoring are derived for both, the individual measures as well as for a waste prevention programme.

    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.

    New Knowledge on Distribution and Abundance of Toxic Microalgal Species and Related Toxins in the Northwestern Black Sea (2022)
    MDPI
    In:  EPIC3Toxins, MDPI, 14(10), pp. 685, ISSN: 2072-6651
    Details
    Publication Date: 2022-10-16
    Description: Numerous potentially toxic plankton species commonly occur in the Black Sea, and phycotoxins have been reported. However, the taxonomy, phycotoxin profiles, and distribution of harmful microalgae in the basin are still understudied. An integrated microscopic (light microscopy) and molecular (18S rRNA gene metabarcoding and qPCR) approach complemented with toxin analysis was applied at 41 stations in the northwestern part of the Black Sea for better taxonomic coverage and toxin profiling in natural populations. The combined dataset included 20 potentially toxic species, some of which (Dinophysis acuminata, Dinophysis acuta, Gonyaulax spinifera, and Karlodinium veneficum) were detected in over 95% of the stations. In parallel, pectenotoxins (PTX-2 as a major toxin) were registered in all samples, and yessotoxins were present at most of the sampling points. PTX-1 and PTX-13, as well as some YTX variants, were recorded for the first time in the basin. A positive correlation was found between the cell abundance of Dinophysis acuta and pectenotoxins, and between Lingulodinium polyedra and Protoceratium reticulatum and yessotoxins. Toxic microalgae and toxin variant abundance and spatial distribution was associated with environmental parameters. Despite the low levels of the identified phycotoxins and their low oral toxicity, chronic toxic exposure could represent an ecosystem and human health hazard.

    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.
