Das Projekt "3R-Studie - Reduce, Reuse, Recycle für die G8-Staaten" wird/wurde ausgeführt durch: bifa Umweltinstitut GmbH.bifa hat ein Vorhaben für die G8- Staaten bearbeitet, in dem die Entwicklungen in Deutschland innerhalb der neun Handlungsfelder ( Actions ) des Kobe 3R Action Plan dargestellt werden. Mit der 3R-Initiative beabsichtigen die G8-Staaten seit 2004 eine bessere Verankerung der Nachhaltigkeit im Umgang mit Rohstoffen durch die stärkere Förderung der drei Prinzipien Reduce, Reuse, Recycle , abgekürzt 3R , in den nationalen Abfallwirtschaftspolitiken. Im Rahmen der Beauftragung untersuchte bifa, welche Punkte aus dem Kobe 3R Action Plan bereits hinreichend durch bestehende Entwicklungen bzw. ergriffene Maßnahmen abgedeckt sind, bei welchen Aktionen noch Lücken bestehen und wie diese Lücken gefüllt werden können. Legt man die drei Zielsetzungen des Kobe 3R Action Plan und die ihnen zugeordneten Handlungsfelder als Prüfraster über die deutsche Abfallwirtschaftspolitik, lässt sich ein sehr hoher Erfüllungsgrad feststellen. Ein erheblicher Teil der vorgeschlagenen Handlungsoptionen war in Deutschland bereits vor 2008 durch konkrete Maßnahmen umgesetzt worden. Für einen anderen Teil wiederum lässt sich der Ursprung, z. B. in Form eines ersten Gesetzentwurfs, auf die Zeit vor 2008 zurückdatieren, die Umsetzung durch die Veröffentlichung im Bundesgesetzblatt aber fand 2008-2011 statt. Einige Regelungen setzen Richtlinien oder Verordnungen der EU, die ihrerseits zum Teil auf Bestrebungen Deutschlands hin zustande kamen, in nationales Recht um. Mit dem in einer fortgeschrittenen Version vorliegenden Entwurf eines novellierten Kreislaufwirtschaftsgesetzes vollzieht Deutschland einen weiteren wichtigen Schritt hin zu einer Abfallwirtschaft, deren Markenzeichen insbesondere eine hohe Ressourceneffizienz ist. Dennoch verbleiben Optimierungspotenziale, zu deren Ausschöpfung bifa Vorschläge für das Bundesumweltministerium erarbeitet hat. Im Zuge des Projekts analysierte bifa u. a. die Importe und Exporte notifizierungspflichtiger Abfälle. Der Saldo hat sich den bifa-Analysen zufolge seit 1998 umgekehrt: Wurden 1998 noch etwa doppelt so viel notifizierungspflichtige Abfälle exportiert wie importiert, hat sich der Import seitdem vervierfacht und die Exporte sind sogar leicht gesunken. Ein wichtiger Grund ist die Verfügbarkeit von Behandlungs- und Verwertungskapazitäten von hoher Leistungsfähigkeit in Deutschland. Die Schadstoffentfrachtung von Abfällen aus Ländern mit einer wenig entwickelten Entsorgungsinfrastruktur führt jedoch innerhalb der deutschen Öffentlichkeit immer wieder zu Kontroversen. Methoden: Analyse und Moderation sozialer Prozesse.
Das Projekt "Biogenic soil structures: feedbacks between bioactivity and spatial heterogeneity of water storage and fluxes from plot to hillslope scale" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Technische Universität Braunschweig, Institut für Geoökologie, Abteilung Umweltsystemanalyse.Soil structure determines a large part of the spatial heterogeneity in water storage and fluxes from the plot to the hillslope scale. In recent decades important progress in hydrological research has been achieved by including soil structure in hydrological models. One of the main problems herein remains the difficulty of measuring soil structure and quantifying its influence on hydrological processes. As soil structure is very often of biogenic origin (macropores), the main objective of this project is to use the influence of bioactivity and resulting soil structures to describe and support modelling of hydrological processes at different scales. Therefore, local scale bioactivity will be linked to local infiltration patterns under varying catchment conditions. At hillslope scale, the spatial distribution of bioactivity patterns will be linked to connectivity of subsurface structures to explain subsurface stormflow generation. Then we will apply species distribution modelling of key organisms in order to extrapolate the gained knowledge to the catchment scale. As on one hand, bioactivity influences the hydrological processes, but on the other hand the species distribution also depends on soil moisture contents, including the feedbacks between bioactivity and soil hydrology is pivotal for getting reliable predictions of catchment scale hydrological behavior under land use change and climate change.
Das Projekt "Schwerpunktprogramm (SPP) 1006: Bereich Infrastruktur - Internationales Kontinentales Bohrprogramm (ICDP); International Continental Drilling Program (ICDP), Sub project: Determination of the depth of rhyolitic magma chambers in the Snake River Plain province, USA - An experimental calibration" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Leibniz Universität Hannover, Institut für Mineralogie.The investigation of high-silica rhyolitic rocks collected in the recent ICDP drilling from the Snake River Plain (SRP) volcanic province (western United States) as well as rocks from the adjacent rhyolitic complexes offers a unique opportunity to track the evolution of magma storage conditions in time and space in the 'Yellowstone hotspot' intracontinental volcanic province. The application of various geothermometers which can be used to determine pre-eruptive temperatures show a general trend indicating a general decrease of temperature over the last 16 Ma. However, the depth (or pressure) of the magma chambers is difficult to constrain and remains mainly unknown because the mineral assemblage in the rhyolitic systems is not suitable for geobarometry. As an alternative to mineral compositions, the silica content of rhyolitic melts can be used to constrain pressure, provided that the silicate melts have cotectic compositions (melts coexisting with quartz and feldspar), which is the case for most SRP rhyolites. From studies in synthetic systems, it is well known that the silica content of cotectic melts decreases with increasing pressure and that it may be used as barometer in pressure ranges of ca 1000 - 50 MPa. However, the evolution of silica content with pressure is not calibrated for natural systems containing up to 2 wtProzent Cao and 4 wtProzent FeO. In this study, we plan to determine the role of pressure on the silica content of cotectic melts compositions relevant for SRP compositions. The experimental data are crucial to interpret the natural glass compositions (matrix glass and glass inclusions) analyzed in the ICDP core samples and will be used to extract quantitative information on the depth of magma storage prior to eruption. The dataset obtained from various eruptive events (samples from ICDP drillings and other SRP rhyolites) will be used to check if there is an evolution of the depth of magma storage over the lifetime of the 'Yellowstone hotspot' in the last 16 Ma and if there is a correlation between the pre-eruptive pressure, the volume of erupted material, the temperature (or differentiation level) and the water activity of magmas. This study will be conducted in close cooperation with other U.S. groups who are in charge of the analysis of ICDP rhyolitic samples. It is emphasized that the experimental database obtained in this project can also be applied to other case studies (high silica rhyolites, A-type granites).
Das Projekt "Supporting the role of the Common agricultural policy in LAndscape valorisation: Improving the knowledge base of the contribution of landscape Management to the rural economy (CLAIM)" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Universita di Bologna, Alma Mater Studiorum.The provision of public goods (including landscape services) in rural areas is recognized as one of the key topics for the future of agriculture and rural policy. Agriculture plays a major role in landscape management through its complex interlinkages with landscape features. In turn, the Common Agricultural Policy (CAP) remains an important driver of landscape management due to its importance as a determinant of farming activities in the EU. The main objective of the CLAIM project is to provide the knowledge base to support an effective CAP policy design in the direction of improved landscape management, particularly providing insights into the ability of landscape to contribute to the production of added value for society in rural areas. CLAIM is focused in particular on understanding and enhancing the contribution of landscapes management to socio-economic development and agricultural competitiveness in rural areas. This will be based on a pragmatic consideration of landscape services and their analysis through a mixed-method approach, taking into account the wider EU policy strategies (in particular related to innovation and the bioeconomy). The main expected result of the CLAIM project is an evidence-based policy support framework on the different and possible contributions of agriculture and the CAP to landscape management. The framework will be mainly developed and validated through a set of 9 case studies, a strong involvement of stakeholders at different territorial levels and a wide coverage of the perspectives of EU and candidate countries. The framework will finally take the practical form of a web-based manual to be implemented in accordance to stakeholders needs and indications.
Das Projekt "Interreg IV B North West Europe (NWE), Green Cook - Transnational strategy for global sustainable food management" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Universität Stuttgart, Institut für Siedlungswasserbau, Wassergüte- und Abfallwirtschaft, Lehrstuhl für Abfallwirtschaft und Abluft.GreenCook is aimed at reducing food wastage and to make the North-West Europe a model of sustainable food management, by in-depth work on the consumer / food relationship thanks to a multisectoral partnership. Food wastage is a challenging problem, directly linked with the question of waste, consumption and climate change. A quarter of the food produced in the world each year ends up in the dustbin, without having been consumed. Food wastage, a reflection of our overconsumption society, also reinforces social inequalities and is ethically unacceptable. The negative impacts of this wastage are real: for households (useless expenditure), for local authorities (overproduction of waste to be treated, increased costs), for the environment (pointless use of resources and pollution), and for the economy (falling prices). There is a pressing need, for consumers to respect food and food producers again, to enjoy the pleasure of healthy and tasty eating again, to rediscover culinary know-how, and to optimise food presentation, storage and conservation. Lately, tools and methods are under experimentation to help consumers to improve their food management while controlling their purchasing power. They aim at changing behaviour or altering the offer (at the supermarket, in the restaurant or in the canteen). It is alas hard for them to be generalised, because of the complexity of the levers that have to be activated. GreenCooks ambition is to create this lever effect, by generating a dynamic that motivates all of the food players and by throwing pathbreaking bridges with the fields of health, welfare and economic development. Its diversified partnership intends to show the added value of united, transversal action, and to influence EU policies, in order to get a new European sustainable food model to emerge.

Das Projekt "Engine representative internal cooling knowledge and applications (ERICKA)" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Rolls-Royce Deutschland Ltd & Co KG.The goal of ERICKA is to directly contribute to reductions in aircraft engine fuel consumption with a targeted contribution of 1Prozent reduction in SFC relative to engines currently in service. The fuel efficiency of a jet engine used for aircraft propulsion is dependent on the performance of many key engine components. One of the most important is the turbine whose efficiency has a large influence on the engine fuel consumption and hence its CO2 emissions. The turbine must operate with high efficiency in the most hostile environment in the engine. The design of turbine cooling systems remains one of the most challenging processes in engine development. Modern high-pressure turbine cooling systems invariably combine internal convection cooling with external film cooling in complex flow systems whose individual features interact in complex ways. The heat transfer and cooling processes active are at the limit of current understanding and engine designers rely heavily on empirical tools and engineering judgement to produce new designs. ERICKA will provide a means of improving turbine blade cooling technology that will reduce turbine blade cooling mass-flow relative to that required using existing technology. A reduction in cooling mass-flow leads directly to improved component and engine efficiency. The improved technology for turbine cooling developed by ERICKA will also enable low NOx combustion chambers to be included in future engines. ERICKA will undertake research to furnish better understanding of the complex flows used to internally cool rotating turbine blades. This will be achieved by: 1) Acquisition of high quality experimental data using static and rotating test facilities 2) Development of cooling design capability by enhancement of computer codes that will exploit these experimental data ERICKA groups 18 partners representing the European aero engine industry, five SMEs and a set of leading academic institutions.

Das Projekt "Evolutionary Conflicts and their Impact on Speciation, Evolutionary Conflicts and their Impact on Speciation (follow-up)" wird/wurde gefördert durch: Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung. Es wird/wurde ausgeführt durch: Eidgenössische Technische Hochschule Zürich, Institut für Integrative Biologie.In addition to recognizing natural selection as a universal mechanism in evolution, Darwin also saw the importance of sexual selection, yet the two have been traditionally treated largely in isolation. Here I propose to apply experimental evolution (exposing experimental populations to controlled specific selective pressures over many generations in the laboratory) to the ideally suited model system Tribolium castaneum to explore how these evolutionary forces interact and impact on the key processes underlying biodiversity. Understanding how these fundamental forces, singly and in conjunction, influence species divergence remains a major challenge in evolutionary biology. Participation of sexual selection in driving speciation is supported by substantial theoretical evidence. Theory further suggests that evolutionary conflicts (such as between the sexes or between host and parasite) might also accelerate extinction. Additional complexity is introduced by including the environmental context, linking back to natural selection. Direct experimental tests of the above concepts are essentially lacking. I will explicitly target this gap by exploiting powerful experimental evolution, incorporating the interplay between sexual selection intensity, host-parasite conflict, and adaptation to increasing temperature. Projects will assess how selection under evolutionary conflict and environmental change affects both adaptation and extinction rates, aiming to elucidate underlying mechanisms. Additionally, building on clear phenotypic divergence in key traits across experimental evolution lines, I will significantly expand on previous work by assessing patterns of divergence in gene expression, concentrating on target genes associated with reproduction, immunity and heat shock. This research will be of particular interest to scientists working in the fields of evolutionary biology and behavioural ecology, but also to ecologists, reproductive biologists, and conservation biologists. As Tribolium beetles are widespread agricultural pests, results will also be relevant to more applied researchers.
Das Projekt "Implications of the biogenic character on aquatic food chain accumulation of elemental selenium" wird/wurde gefördert durch: Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung. Es wird/wurde ausgeführt durch: Fachhochschule beider Basel - Nordwestschweiz.Selenium is a double edged chemical element, since it is both essential yet highly toxic. Besides its high acute toxicity, selenium is characterized to be strongly bioconcentrated from dissolved selenium species (selenite, selenate, selenoaminoacids) in aquatic primary producers and further biomagnified during food chain transfer. In consequence, water borne selenium concentrations of as little as 2 myg / L have been documented to cause severely adverse effects on top predators such as water birds and fish. Although the ecotoxic impact was first noticed in the early 1980s, to date no definitive solution has been found to remediate selenium contaminated drainage and waste waters. Due to the water insolubility of elemental selenium, the dogma that 'elemental selenium is not bioavailable and not toxic' dominates current scientific literature and forms the basis for various remediation approaches using microorganisms to convert selenium oxyanions to elemental selenium. However, a number of considerations and recent studies suggest that the dogma might only be true for 'bulk' elemental selenium, yet not for microbially formed, so called biogenic selenium. Biogenic differs from bulk elemental selenium considerably regarding its physico-chemical properties. Biogenic elemental selenium consists of nanometer sized spheres, which do not crystallize to larger particles of trigonal elemental selenium, the thermodynamically stable allotrope. The latter is due to stabilization by proteins associated with the particles. As a consequence, biogenic elemental selenium does not settle yet remains in waters as a colloidal suspension, thus being subject to uptake by biota. Although the general bioavailability of biogenic elemental selenium has been proven, it has not been studied in detail, in particular not in aquatic environments. We aim at quantifying acute and chronic toxicity in the model organism Daphnia magna, elucidating the underlying mechanism of toxicity. Furthermore, we will quantify biogenic elemental selenium uptake, depuration and biotransformation to proteinous forms (the species most relevant for trophic transfer). Thus we will be able to deliver an improved model of selenium food chain transfer in aquatic environments, the basis for appropriate selenium risk assessment. During the course of the proposed research, such questions as the following will be answered: - Is biogenic elemental selenium bioavailable and / or toxic to Daphnia magna? Which are the mechanisms underlying toxicity? - To which extent is biogenic selenium biotransformed to proteinous (highly bioaccumulative) species? Does biogenic elemental selenium represent a significant entrance port for selenium at base of aquatic food chain?
Das Projekt "Strengthening research capacity and knowledge transfer in Integrated Pest Management at different institutional levels to improve sustainable agriculture in Albania" wird/wurde gefördert durch: Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung. Es wird/wurde ausgeführt durch: CABI Biosciene, Switzerland.Background: As Albanian agriculture began returning to the private sector in the late 1990s, it was evident that the infrastructure was weak, resulting in low production standards and inefficient use of resources. Despite efforts in the last two decades to restructure and strengthen the agriculture sector, it still remains underdeveloped, characterised by inadequate research, development, transfer of knowledge and modernisation. Farmers still rely on outdated, inefficient pesticide application equipment and often use highly toxic pesticides that are banned in the rest of Europe. Within the agricultural schools and universities, there is a weak capacity for agricultural research and knowledge transfer stemming from several infrastructure-related shortcomings, such as lack of resources and contact with the global scientific community. This constrains the international competitiveness of researchers as well as the training of students in modern pest management approaches. The limited capacity for technology transfer hinders the generation of science-based solutions for local agricultural problems and an ineffective advisory service means that farmers remain disconnected from agricultural research and technology development. Aim: This project aims to build the capacity of relevant institutions in research and knowledge transfer in integrated pest management (IPM); a sustainable pest management approach that reduces overreliance on chemical pesticides and alleviates the negative impacts of agriculture on human health and the environment. The project also aims to strengthen the infrastructure required to improve the quality of agricultural production and enable self-reliance in developing and implementing sustainable IPM solutions. Significance: Through the integration of effective theoretical and practical IPM training into higher education, this project will better prepare students for future employment in an agricultural profession and increase the overall IPM knowledge base within the agricultural sector. The provision of relevant resources and training will enhance capacity for conducting IPM-related research as well as foster integration into the international scientific community. Finally, strengthening the link between research and farmers will provide an effective channel through which to disseminate practical IPM solutions to farmers. In taking an institutional partnership approach, this project will consolidate the linkages between all key IPM stakeholders and create the infrastructure required to promote awareness, communication and institutionalisation of IPM along the whole chain of agricultural research, education, policy and practice.
Das Projekt "Individual Grant; Ensemble modelling of hydrological and nitrogen fluxes in mesoscale catchments" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Universität Gießen, Institut für Landschaftsökologie und Ressourcenmanagement, Professur für Landschafts-, Wasser- und Stoffhaushalt.Uncertainty estimation in hydro-biogeochemical modeling is an ongoing area of research that focuses primarily on the investigation of stochastic model uncertainty. The evaluation of structural model uncertainty remains unusual, however there are various techniques available to quantify structural uncertainty. Ensemble modeling is one such technique that is commonly used in climatology and meteorology; disciplines where the structural uncertainty of predictive models has long been established. Its application in hydrological modeling is, however, much less common. Here we propose to evaluate structural uncertainty through *P ensemble modeling, using a set of four models to predict hydrological and nitrogen fluxes: SWAT, LASCAM, HBV-N and CMF-N. The models were selected to represent the range of complexity found in catchment scale modeling, from conceptual models to physically-based approaches, and from lumped to fully distributed descriptions. The GLUE concept is applied to quantify parameter uncertainty. This approach leads to the formulation of single-model ensembles. These single-model ensembles are then combined to produce different sets of probabilistic and deterministic multi-model ensembles. These multi-model ensembles are used to quantify the contribution of structural errors to overall predictive uncertainty. The development of conditional multi-model ensembles represents a large component of the work plan. In this case, the selection of the multi-model ensemble members is based on the capability of different model structures and parameterizations to capture certain conditions of the investigated catchments such as high-low flow, freeze-thaw cycles, or rewetting after extended droughts. The ensemble model is applied to German, Swedish and Australian catchments, and covers a broad range of different climatic boundary conditions, land uses and levels of anthropogenic disturbances.
