With the 'twin transition', the European Union aims to combine digitalisation and sustainability in order to achieve the United Nations Sustainable Development Goals. The research project "Digitalisation and sustainability at EU level" examined the opportunities and risks of digitalisation for the implementation of the 2030 Agenda for Sustainable Development. The analysis showed that these two topics are often not integrated. Recommendations were developed for digital circular economy, sufficiency and environmental justice. The research findings suggest that environmental and social justice should be at the forefront of future efforts to promote a sustainable digital future. Veröffentlicht in Texte | 35/2025.
Das Projekt "Flood risk in a changing climate (CEDIM)" wird/wurde gefördert durch: Karlsruher Institut für Technologie (KIT), Center for Disaster Management and Risk Reduction Technology (CEDIM). Es wird/wurde ausgeführt durch: Karlsruher Institut für Technologie (KIT), Institut für Meteorologie und Klimaforschung, Department Troposphärenforschung.Aims: Floods in small and medium-sized river catchments have often been a focus of attention in the past. In contrast to large rivers like the Rhine, the Elbe or the Danube, discharge can increase very rapidly in such catchments; we are thus confronted with a high damage potential combined with almost no time for advance warning. Since the heavy precipitation events causing such floods are often spatially very limited, they are difficult to forecast; long-term provision is therefore an important task, which makes it necessary to identify vulnerable regions and to develop prevention measures. For that purpose, one needs to know how the frequency and the intensity of floods will develop in the future, especially in the near future, i.e. the next few decades. Besides providing such prognoses, an important goal of this project was also to quantify their uncertainty. Method: These questions were studied by a team of meteorologists and hydrologists from KIT and GFZ. They simulated the natural chain 'large-scale weather - regional precipitation - catchment discharge' by a model chain 'global climate model (GCM) - regional climate model (RCM) - hydrological model (HM)'. As a novel feature, we performed so-called ensemble simulations in order to estimate the range of possible results, i.e. the uncertainty: we used two GCMs with different realizations, two RCMs and three HMs. The ensemble method, which is quite standard in physics, engineering and recently also in weather forecasting has hitherto rarely been used in regional climate modeling due to the very high computational demands. In our study, the demand was even higher due to the high spatial resolution (7 km by 7 km) we used; presently, regional studies use considerably larger grid boxes of about 100 km2. However, our study shows that a high resolution is necessary for a realistic simulation of the small-scale rainfall patterns and intensities. This combination of high resolution and an ensemble using results from global, regional and hydrological models is unique. Results: By way of example, we considered the low-mountain range rivers Mulde and Ruhr and the more alpine Ammer river in this study, all of which had severe flood events in the past. Our study confirms that heavy precipitation events will occur more frequently in the future. Does this also entail an increased flood risk? Our results indicate that in any case, the risk will not decrease. However, each catchment reacts differently, and different models may produce different precipitation and runoff regimes, emphasizing the need of ensemble studies. A statistically significant increase of floods is expected for the river Ruhr in winter and in summer. For the river Mulde, we observe a slight increase of floods during summer and autumn, and for the river Ammer a slight decrease in summer and a slight increase in winter.
Das Projekt "CDM Market Support Study" wird/wurde gefördert durch: kfw Bankengruppe. Es wird/wurde ausgeführt durch: Ecofys Germany GmbH.The Clean Development Mechanism (CDM) suffers from a price level for certificates that went down to almost zero in a period less than a year. Additionally, no short-term price recovery is expected which could incentivise new projects. A risk is that market participants leave the market and the valuable CDM knowledge base on GHG mitigation and quantification will be lost. The CDM Market Support Study analyses the actual price vulnerability of projects and identifies various financing and project type opportunities for project developers and for (institutional public) investors who intent to support the CDM project continuation and the further development of the CDM framework. The study also shows how the current regulatory framework of the CDM can be maintained by transferring it to future mechanisms. This could be a chance to develop the CDM from a pure market-based instrument towards an integrated part within future market-based and also policy-based instruments. The CDM can provide useful components to currently discussed or tested instruments such as the NMM (New Market Mechanism), the FVA (Framework for Varios Approaches), NAMAs (Nationally Appropriate Mitigation Actions) or results-based financing approaches. The study was financed by the German KfW-managed PoA Support Centre . The aim of the PoA-Support-Centre Germany is to support the development of Programmes of Activities (PoAs) under CDM and JI (Joint Implementation) worldwide.
Das Projekt "Staub - Spiegel der Umwelt - Eine Public Science Ausstellung im Wissenschaftszentrum Umwelt" wird/wurde ausgeführt durch: Universität Augsburg - Wissenschaftszentrum Umwelt (WZU).Täglich sammeln wir Staub - wenn wir uns in einem Raum aufhalten, wenn wir durch eine Wiese oder über eine Straße gehen oder auch in einem Buch lesen - und täglich versuchen wir, ihn wieder loszuwerden. Unser Drang nach Reinheit hat eine ganze Industrie entstehen lassen, die von Staubsaugern bis zu High-Tech-Filtern alle Arten von kleinen und größeren Hilfsmitteln anbietet. Für die Wissenschaft ist Staub kein Dreck. Was für den Alltagsmenschen ein Symbol der Zerstörung ist, birgt für den Forscher viele wichtige Informationen. Denn aus einer Analyse des Staubes lässt sich vieles über unsere gegenwärtige und sogar über vergangene Umwelten lernen. Zum anderen erobert die Wissenschaft mit Mikro- und Nanotechnologien die Welt des Winzigen. Denn das sehr Kleine eröffnet besondere technische Chancen. Auch diese aktuellen Entwicklungen und die damit verbundenen Chancen und Risiken soll die Ausstellung aufzeigen. Die Ausstellung wurde von November 2004 bis Oktober 2005 im Wissenschaftszentrum Umwelt der Universität Augsburg gezeigt werden. Sie umfasst 30-40 Exponate, darunter mehrere Hands-on-Exponate. Leihgeber für spezielle Objekte sind das Bundeskriminalamt, das Landesamt für Umweltschutz in Bayern, das Umweltbundesamt, der Deutsche Wetterdienst und weitere Institutionen. Ein ausstellungsbegleitendes Buch wird beim Oekom Verlag in München erscheinen. Im Anschluss an die Augsburger Station ging die Ausstellung auf Wanderschaft und wurde inzwischen an sechs weiteren Stationen gezeigt. Die Zahl der Besucher liegt bereits weit über 100.000.

Das Projekt "Economic/Climate Recovery Scorecards" wird/wurde gefördert durch: E3G. Es wird/wurde ausgeführt durch: Ecofys Germany GmbH.As global leaders head to the G20 summit to consider solutions to the current global economic crisis, a new report prepared by Ecofys and Germanwatch for WWF and E3G reveals that many of the economic recovery packages being discussed are a missed opportunity in terms of stimulating a green recovery, and actually run the risk of locking the world into a high-carbon future. The report provides the most detailed and comprehensive analysis to date of the proposed 'stimulus' packages of five key countries - France, Germany, Italy, the UK and the US - as well as the package agreed by the European Union as a whole.
Das Projekt "Improving the Livelihood of the Rural Population through the Production of Bushmeat in Ghana" wird/wurde gefördert durch: Deutsche Gesellschaft für Technische Zusammenarbeit (GTZ) GmbH / Stiftung Walderhaltung in Afrika. Es wird/wurde ausgeführt durch: Universität Hamburg, Arbeitsbereich für Weltforstwirtschaft und Institut für Weltforstwirtschaft des Friedrich-Löffler-Institut, Bundesforschungsinstitut für Tiergesundheit.Background: Ghanas transition forests, neighbouring savannahs and timber plantations in the Ashanti region face a constant degradation due to the increased occurrence of fires. In most cases the fires are deliberately set by rural people for hunting purposes. Main target is a cane rat, here called grasscutter (Thryonomys swinderianus), whose bushmeat is highly esteemed throughout the country. The animal is a wild herbivorous rodent of subhumid areas in Africa south of the Sahara. The grasscutter meat is an important source of animal protein. Existing high-value timber plantations (mainly Teak, Tectona grandis) are affected by fires for hunting purposes. Thus resulting in growth reduction, loss of biomass or even complete destruction of the forest stands. It became obvious that solutions had to be sought for the reduction of the fire risk. Objectives: Since 2004 the Institute for World Forestry of the Federal Research Centre for Forestry and Forest Products, Hamburg, Germany is cooperating with a Ghanaian timber plantation company (DuPaul Wood Treatment Ltd.) the German Foundation for Forest Conservation in Africa (Stiftung Walderhaltung in Afrika) and the Center for International Migration with the purpose to improve the livelihood of the rural population in the surroundings of the forest plantation sites and simultaneously to safeguard and improve the timber plantations. The introduction of grasscutter rearing systems to local farmers accompanied by permanent agricultural and agroforestry practices appeared to be a promising approach for the prevention of fires in the susceptible areas. Additionally a functioning grasscutter breeding system could contribute to the improvement of food security, development of income sources and the alleviation of poverty. The following measures are implemented: - Identification of farmers interested in grasscutter captive breeding, - Implementation of training courses for farmers on grasscutter rearing, - Delivery of breeding animals, - Supervision of rearing conditions by project staff, - Development of a local extension service for monitoring activities, - Evaluation of structures for grasscutter meat marketing. Results: After identification of key persons for animal rearing training courses were successfully passed and animals were delivered subsequently. Further investigations will evaluate the effects of the grasscutter rearing in the project region. This will be assessed through the - Acceptance of grasscutter rearing by farmers, - Success of the animal caging, - Reproduction rate, - Meat quality, - Marketing success of meat, - Reduction of fire in the vicinity of the timber plantations, - Improvement of peoples livelihood.
