    Principles and design scenarios for sustainable urban food logistics (2022)
    Details
    Publication Date: 2023-05-15
    Description: Food and nutrition systems are linked to all Sustainable Development Goals (SDGs), which makes their transition toward social-ecological behavior patterns crucial for an overarching sustainability transformation. The perspective of (urban) logistics is of special interest. It couples the production and consumption physically and virtually. In this context, we shed light on the design of the turnover point of food in urban areas from the supply chain toward consumers and contribute to an overarching systemic perspective toward establishing a sustainable multilevel food system. We describe current patterns in urban food systems and propose several principles for sustainable design of (urban) food systems based on concepts such as (regional) collaboration and food literacy. Using these principles, we provide four design scenarios that concretely imagine future urban food consumption and production patterns titled "slow stock supply service," "deliver into the daily walk," "central district food depot," "super food action place." With this work we provide a starting for reflecting whether certain combinations of principles actually lead to patterns of daily life that are feasible, acceptable, or desirable. Moreover, we provide an initial qualitative assessment to stimulate further research that explores scenario pathways and incorporates additional indicators regarding the impact on social-ecological. We open up various research questions with regard to the overarching question of how urban food logistics should be designed to be consistent with the SDGs.

    Sustainable transformation of Jordan's energy system : development of a phase model (2021)
    Amman : Friedrich-Ebert-Stiftung
    Details
    Publication Date: 2024-01-18
    Description: A clear understanding of socio-technical interdependencies and a structured vision are prerequisites for fostering and steering a transition to a fully renewables-based energy system. To facilitate such understanding, a phase model for the renewable energy (RE) transition in the Middle East and North Africa (MENA) countries has been developed and applied to the country case of Jordan. It is designed to support the strategy development and to serve as a guide for decision-makers. The analysis shows that Jordan has taken essential steps towards a RE transition. According to the MENA energy transition phase model, Jordan can be classified as being in a transitional stage between the first phase, "Take-Off Renewables", and the second phase, "System Integration". However, fossil fuels continue to play a dominant role in the Jordanian energy sector, and the fluctuating world market prices for fossil fuels impact the economy. The expansion of domestically produced RE could significantly contribute to reducing Jordan's high imports of fossil fuels. This simultaneously increases energy security and reduces the trade deficit. To move towards a sustainable energy system, Jordan needs to embrace comprehensive flexibility measures. These include developing storage options, improving load management, upgrading the existing grid infrastructure, enhancing energy efficiency, exploring the electrification of end use sectors, and creating strong cooperation between stakeholders.

    Digitalisation for a sustainable food system : opportunities for shaping production and consumption ; a study commissioned by Huawei Technologies Deutschland GmbH (2023)
    Wuppertal : Wuppertal Institut für Klima, Umwelt, Energie
    Details
    Publication Date: 2023-03-24
    Description: The food system faces a multitude of challenges, including high greenhouse gas emissions, threats to biodiversity, increased diet-related diseases due to unbalanced diets, and socially problematic complex supply chains. This requires not only a transformation of the agricultural economy but also a change in the diet and lifestyles of all consumers. Developing and using digital and technological innovations can help to solve these challenges. In this context, the study provides impulses on how digitalisation can contribute to transforming production and consumption and which prerequisites have to be given to achieve this. The study describes the approaches for digitalisation along the value chain. These include optimising the use of resources in agriculture - for example with the help of smart farming - and supporting consumers with digital tools and assistance systems - such as apps designed to support grocery shopping. In addition, new business models and a better connection between production and consumption processes are also possible. This includes, for example, new digital sales channels or tracking and communicating sustainability indicators such as CO2 emissions across all steps of the value chain in order to enable all stakeholders to take reliable action.

    Sustainable transformation of Morocco's energy system : development of a phase model (2024)
    Agdal Rabat : Friedrich-Ebert-Stiftung
    Details
    Publication Date: 2024-01-18
    Description: A clear understanding of socio-technical interdependencies and a structured vision are prerequisites for fostering and steering a transition to a fully renewables-based energy system. To facilitate such understanding, a phase model for the renewable energy (RE) transition in MENA countries has been developed and applied to the country case of Morocco. It is designed to support the strategy development and governance of the energy transition and to serve as a guide for decision makers. Such a phase model could be shared widely as part of Morocco's engagement in international platforms of multilateral collaboration, such as the Energy Transition Council (chaired by the United Kingdom (UK) and managed by the British Embassy - Rabat). The analysis shows that Morocco has fully embarked on the energy transition. According to the MENA phase model, Morocco can be classified as being in the second phase "System Integration of Renewables". Nevertheless, Morocco plans to considerably increase the use of natural gas in order to back up intermittent solar and wind energy sources. The diversification of energy sources and a diverse portfolio of storage options, including solar thermal power and hydrogen, can foster flexibility options. To this end, a roadmap for power-to-X (PtX) should be considered for a smooth transition of the Moroccan energy supply and demand system. The expansion of local REs can significantly contribute to reducing Morocco's high fossil fuel imports that are causing a high fiscal burden. With this regard, energy security can be strengthened. Next to large-scale deployment, decentralisation of the energy system must be built to encourage an energy transition on all societal levels. The results of the analysis along the transition phase model towards 100% RE are intended to stimulate and support the discussion on Morocco's future energy system by providing an overarching guiding vision for energy transition and the development of appropriate policies.

    How compatible are Western European dietary patterns to climate targets? : Accounting for uncertainty of life cycle assessments by applying a probabilistic approach (2022)
    Details
    Publication Date: 2023-05-15
    Description: The food system plays a crucial role in mitigating climate change. Even if fossil fuel emissions are halted immediately, current trends in global food systems may prevent the achieving of the Paris Agreement's climate targets. The high degree of variability and uncertainty involved in calculating diet-related greenhouse gas emissions limits the ability to evaluate reduction potentials to remain below a global warming of 1.5 or 2 degrees. This study assessed Western European dietary patterns while accounting for uncertainty and variability. An extensive literature review provided value ranges for climate impacts of animal-based foods to conduct an uncertainty analysis via Monte Carlo simulation. The resulting carbon footprints were assessed against food system-specific greenhouse gas emission thresholds. The range and absolute value of a diet carbon footprint become larger the higher the amount of products with highly varying emission values in the diet. All dietary pattern carbon footprints overshoot the 1.5 degrees threshold. The vegan, vegetarian, and diet with low animal-based food intake were predominantly below the 2 degrees threshold. Omnivorous diets with more animal-based product content trespassed them. Reducing animal-based foods is a powerful strategy to decrease emissions. However, further mitigation strategies are required to achieve climate goals.

    Turning point Glasgow? : An assessment of the climate conference COP26 (2022)
    Details
    Publication Date: 2023-02-06
    Description: The Glasgow climate conference marked a symbolic juncture, lying half-way between the adoption of the UNFCCC in 1992 and the year 2050 in which according to the IPCC special report on the 1.5°C limit net zero CO2 emissions need to be reached, globally, in order to maintain a good chance of achieving the 1.5°C limit. This article undertakes an assessment of what the UNFCCC and in particular the Paris Agreement and its implementation process have actually achieved so far up to and including the results of the Glasgow conference. The article discusses efforts at ambition raising both within and outside the formal diplomatic process, the finalization of the implementation rules of the Paris Agreement, as well as progress on gender responsiveness, climate finance, adaptation and loss and damage. In summary, the Paris Agreement and its implementation can be considered a success as it is having a discernible impact on the behavior of parties as well as on non-party actors. However, significant further efforts will be required to actually achieve the objectives of the Agreement.

    A generative toolkit to help raise industrial design students' awareness of low metal recycling rates (2024)
    Cambridge : Cambridge University Press
    Details
    Publication Date: 2024-05-31
    Description: Education for Sustainable Development requires raising individuals' awareness of problems relevant to the environment. We designed a Generative Toolkit that supports industrial design students carrying out a Speculative Design task and through this process initiates greater problem awareness of low metal recycling rates. In this paper we give insights into the Toolkit's theoretical derivation and the design process. Findings from testing suggest that there are several opportunities for improvement, such as considering further content-related competencies in the Toolkit's design.

    COT - Circle of Tools : Entwicklung und Erprobung geschlossener CE-Konzepte für die metallverarbeitende Werkzeug- und Schneidwarenindustrie (2024)
    Remscheid : TKM GmbH
    Details
    Publication Date: 2024-06-07
    Description: Das zentrale Anliegen des Projektes besteht darin, regionale Stoffkreisläufe in der metallverarbeitenden Industrie zu schließen - mit einem Schwerpunkt auf (Hand-) Werkzeuge und Schneidwaren - sowie dies durch den Einsatz digitaler Technologien zu organisieren und zu optimieren. Das Ziel ist, Ressourcen- und Energieverbräuche zu reduzieren sowie ökonomische Vorteile für die Unternehmen zu realisieren. Im Detail soll es darum gehen, verschlissene metallische Produkte am End-of-Life nicht einer Verwertung durch Umschmelzen zuzuführen, sondern durch Remanufacturing und Repurposing die Nutzungsdauer der mit hohem Energie- und Ressourcenaufwand erzeugten Metalle zu verlängern. Diese Ansätze sollen unternehmensübergreifend aufgestellt werden und erfordern eine digital unterstützte Logistikkette sowie eine vollständige Rückverfolgbarkeit. Eine Rückführung verschlissener Maschinenmesser lohnt sich nach derzeitigem Kenntnisstand nicht, wenn dieses Material nur den Schrottpreis aufweist. Im Projekt "Circle of Tools" soll daher ein neues Geschäftsmodell entwickelt werden, das darauf basiert, sortenreine, qualitativ hochwertige Materialien entweder im primären Herstellungsprozess zu nutzen oder zur Weiterverarbeitung in andere Herstellungsprozesse unternehmensübergreifend zu integrieren. Neben den rein technischen Möglichkeiten werden betriebswirtschaftliche Faktoren, das Ressourceneffizienzpotenzial und der rechtliche Rahmen untersucht. Die in der europäischen Abfallrahmenrichtlinie und dem deutschen Kreislaufwirtschaftsgesetz verankerte Abfallhierarchie geht von der grundsätzlichen ökologischen Vorteilhaftigkeit der unterschiedlichen Stufen aus. Während das stoffliche Recycling von Produkten in der Regel vorteilhafter ist als ihre thermische Verwertung oder Deponierung, sind Reuse/Kaskadennutzung demnach ökologisch vorteilhafter als sämtliche Recyclingtechnologien. Die Datenlage ist hier jedoch im Vergleich zu vielen Recyclingtechnologien noch äußerst lückenhaft und unsystematisch. Einzelne Untersuchungen weisen jedoch auf signifikante Ressourceneffizienzpotenziale hin. Abschätzungen zeigen, dass die in diesem Vorhaben angedachte Reuse-/Kaskadennutzung zu einer Einsparung von 300 Tonnen Primär-Werkzeugstahl führen könnte. Das Vorhaben kann diese signifikanten Potenziale nachweisen und gleichzeitig geeignete und übertragbare Geschäftsmodelle aufzeigen. Auf Grundlage der empirischen Erhebungen werden im Projekt genaue Wirkungen berechnet für folgende Fragen: (1) Welche Mengen an Rohstoffe können durch Remanufacturing/Repurposing eingespart werden? (2) Welche ökonomische Wertschöpfung ist damit zu erzielen? (3) Wie ist ein Remanufacturing/Repurposing im Vergleich zu anderen Verwertungsverfahren ökologisch und ökonomisch einzuschätzen?

    Diversity of Sporocadaceae (pestalotioid fungi) from Rosa in China (2022)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 49 no. 1, pp. 201-260
    Details
    Publication Date: 2024-03-20
    Description: Rosa (Rosaceae) is an important ornamental and medicinal plant genus worldwide, with several species being cultivated in China. Members of Sporocadaceae (pestalotioid fungi) are globally distributed and include endophytes, saprobes but also plant pathogens, infecting a broad range of host plants on which they can cause important plant diseases. Although several Sporocadaceae species were recorded to inhabit Rosa spp., the taxa occurring on Rosa remain largely unresolved. In this study, a total of 295 diseased samples were collected from branches, fruits, leaves and spines of eight Rosa species (R. chinensis, R. helenae, R. laevigata, R. multiflora, R. omeiensis, R. rugosa, R. spinosissima and R. xanthina) in Gansu, Henan, Hunan, Qinghai, Shaanxi Provinces and the Ningxia Autonomous Region of China. Subsequently 126 strains were obtained and identified based on comparisons of DNA sequence data. Based on these results 15 species residing in six genera of Sporocadaceae were delineated, including four known species (Pestalotiopsis chamaeropis, Pes. rhodomyrtus, Sporocadus sorbi and Spo. trimorphus) and 11 new species described here as Monochaetia rosarum, Neopestalotiopsis concentrica, N. subepidermalis, Pestalotiopsis tumida, Seimatosporium centrale, Seim. gracile, Seim. nonappendiculatum, Seim. parvum, Seiridium rosae, Sporocadus brevis, and Spo. spiniger. This study also represents the first report of Pes. chamaeropis, Pes. rhodomyrtus and Spo. sorbi on Rosa. The overall data revealed that Pestalotiopsis was the most prevalent genus, followed by Seimatosporium, while Pes. chamaeropis and Pes. rhodomyrtus were the two most prevalent species. Analysis of Sporocadaceae abundance on Rosa species and plant organs revealed that spines of R. chinensis had the highest species diversity.

    Causal strands for social bonds : a case study on the credibility of claims from impact reporting (2022)
    Details
    Publication Date: 2023-05-15
    Description: The study investigates if causal claims based on a theory-of-change approach for impact reporting are credible. The authors use their most recent impact report for a Social Bond to show how theory-based logic models can be used to map the sustainability claims of issuers to quantifiable indicators. A single project family (homeownership loans) is then used as a case study to test the underlying hypotheses of the sustainability claims. By applying Bayes Theorem, evidence for and against the claims is weighted to calculate the degree to which the belief in the claims is warranted. The authors found that only one out of three claims describe a probable cause–effect chain for social benefits from the loans. The other two claims either require more primary data to be corroborated or should be re-defined to link the intervention more closely and robustly with the overarching societal goals. However, all previous reported indicators are below the thresholds of the most conservative estimates for fractions of beneficiaries in the paper at hand. We conclude that the combination of a Theory-of-Change with a Bayesian Analysis is an effective way to test the plausibility of sustainability claims and to mitigate biases. Nevertheless, the method is - in the presented form - also too elaborate and time-consuming for impact reporting in the sustainable finance market.
