Das Projekt "Entwicklung von Rebklonen mit besserer Klimaanpassung" wird vom Umweltbundesamt gefördert und von Hochschule Geisenheim University, Zentrum Angewandte Biologie, Institut für Rebenzüchtung und Rebenveredlung durchgeführt. Leistungsfähiges Pflanzgut mit guter Boden- und Klimaanpassung bildet die Grundlage der einer umweltgerechten Pflanzenproduktion. Dies trifft in gleicher Weise auf den Weinbau zu. Neben der Globalisierung der Märkte gehört sicherlich die Klimaveränderung zu den größten Herausforderungen der Gegenwart. Das größte Problem sind in zunehmendem Maß eine wärmere Witterung kombiniert mit Starkregenereignisse während der Traubenreifung und die dadurch ausgelöste Traubenfäule. Wegen der besonderen Bedeutung von Weinlandschaften für Tourismus und Wirtschaft kommt dem Weinanbau hierbei eine besondere gesellschaftliche Bedeutung zu. Die Sicherung der Produktion von gesunden Trauben steht daher an erster Stelle. Ein lockerer Traubenaufbau durch längere Beerenstielchen und/oder kleinere Beeren sowie festere Beerenschale können den Fäulnisbefall stark reduzieren. Sie sind damit ein hervorragendes Resistenzmerkmal und können den Einsatz von Spezial-Botrytiziden erheblich vermindern. Solche Formen der apparenten Resistenz sind sehr stabil, da der Pathogen sie nur schwer überwinden kann und daher hervorragend für langlebige Kulturpflanzen, wie die Weinrebe geeignet. Das Fachgebiet entwickelt von den traditionell in Deutschland angebauten Rebsorten Klone mit lockerem Traubenaufbau und damit einhergehender hoher Resistenz gegen Traubenfäulen. Hierzu wird Zuchtmaterial, das im Rahmen dieses oder weiterer Projekte gesammelt wurde, auf seine Widerstandsfähigkeit gegen Traubenfäulen und weitere weinbaulich relevante Eigenschaften getestet. Ziel ist die Entwicklung von Klonen traditioneller Rebsorten mit hoher Traubenfäuleresistenz kombiniert mit einem stabilen Ertrag und hoher Trauben und Weinqualität, um deutschen Winzern entsprechendes Pflanzgut zur Verfügung zu stellen und damit einerseits die Applikation von Fungiziden zu reduzieren und gleichzeitig die Konkurrenzfähigkeit der heimischen Produktion an ihren traditionellen Standorten sichern zu helfen.
Das Projekt "CFK-Recycling in der Kompetenzregion Augsburg" wird vom Umweltbundesamt gefördert und von bifa Umweltinstitut GmbH durchgeführt. The increasing proportion of carbon fibre reinforced plastics (CFRP) in different branches of industry will result in an increasingly larger quantity of CFRP wastes in future. With regard to improved management of natural resources, it is necessary to add these fibres that require energy-intensive production to effective recycling management. But high-quality material recycling is only ecoefficient if the recycled fibres can be used to produce new high-quality and marketable products. Tests carried out up to now indicate that very good results can be expected for large-scale recycling of carbon fibres by means of pyrolysis. The waste pyrolysis plant (WPP) operated in Burgau is the only large-scale pyrolysis plant for municipal wastes in Germany. Use of this plant to treat CFRP wastes represents a unique opportunity for the whole Southern German economy and in particular the Augsburg economic region. In a study funded by the Bavarian State Ministry of the Environment and Health ('Bayerisches Staatsministerium für Umwelt und Gesundheit'), the specific implementation options for the recovery of carbon fibres from composites by means of large-scale pyrolysis have been under investigation since November 2010. To this end, in the first step a development study was carried out, which in particular examined the options for modifying the Burgau WPP for the recycling of CFRP. The knowledge acquired from the pyrolysis tests, the fibre tests and the economic feasibility study confirmed the positive assessment of the overall concept of CFRP recycling in Burgau. As an overall result, unlimited profitability was found for all scenarios with regard to investments in CFRP recycling in Burgau WPP. The work on the development study was carried out by bifa Umweltinstitut GmbH together with the Augsburg-based 'function integrated lightweight construction project group ('Funktionsintegrierter Leichtbau' - FIL) of the Fraunhofer Institute for Chemical Technology (ICT). Methods: analysis and moderation of social processes, economy and management consulting, process engineering
Das Projekt "Identification of groundwater nitrogen point source contribution through combined distribute temperature sensing and in-situ UV photometry" wird vom Umweltbundesamt gefördert und von Universität Gießen, Institut für Landschaftsökologie und Ressourcenmanagement, Professur für Landschafts-, Wasser- und Stoffhaushalt durchgeführt. Agriculture is the major contributor of nitrogen to ecosystems, both by organic and inorganic fertilizers. Percolation of nitrate to groundwater and further transport to surface waters is assumed to be one of the major pathways in the fate of this nitrogen. The quantification of groundwater and associated nitrate flux to streams is still challenging. In particular because we lack understanding of the spatial distribution and temporal variability of groundwater and associated NO3- fluxes. In this preliminary study we will focus on the identification and quantification of groundwater and associated nitrate fluxes by combining high resolution distributed fiber-optic temperature sensing (DTS) with in situ UV photometry (ProPS). DTS is a new technique that is capable to measure temperature over distances of km with a spatial resolution of ca1 m and an accuracy of 0.01 K. It has been applied successfully to identify and quantify sources of groundwater discharge to streams. ProPS is a submersible UV process photometer, which uses high precision spectral analyses to provide single substance concentrations, in our case NO3-, at minute intervals and a detection limit of less than 0.05 mg l-1 (ca.0.01 mg NO3--Nl-1). We will conduct field experiments using artificial point sources of lateral inflow to test DTS and ProPS based quantification approaches and estimate their uncertainty. The selected study area is the Schwingbach catchment in Hessen, Germany, which has a good monitoring infrastructure. Preliminary research on hydrological fluxes and field observations indicate that the catchment favors the intended study.
Das Projekt "The scalar organization of environmental governance: an institutionalist perspective on the transformation of water and marine governance in the European Union" wird vom Umweltbundesamt gefördert und von Universität Berlin (Humboldt-Univ.), Albrecht Daniel Thaer-Institut für Agrar- und Gartenbauwissenschaften - Ressourcenökonomie durchgeführt. The project aims to theorize the scalar organization of natural resource governance in the European Union. This research agenda is inspired by critical geographers' work on the politics of scale. The research will examine an analytical framework derived from theories of institutional change and multi-level govern-ance to fill this theoretical gap. Furthermore, it will review conceptualizations of the state in institutional economics, evaluate their adequacy to capture the role of the state in the dynamics identified, and develop them further. The described processes may imply shifts in administrative levels, shifts in relations between different levels and changes in spatial delimitations of competent jurisdictions that result, for example, from decentralization or the introduction of river basin oriented administrative structures. The research investigates the implications of two European Directives: the Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD). They both have potentially great significance for the organization of marine and water governance at the level of Member States and below, and adhere to similar regulatory ideas for achieving good ecological status of waters. A multiple case study on changes in the scalar reorganization of marine and water governance that result from the implementation of the Directives will be carried out. It will rely on qualitative and quantitative data gathering based on semi-structured interviews and review of secondary and tertiary sources looking at Portugal, Spain, and Germany. It specifically addresses the role of social ecological transactions, the structure of decision making processes and the role of changes in contextual factors (such as ideologies, interdependent institutions and technology).
Das Projekt "Late-Glacial and Holocene vegetational stability of southern South America" wird vom Umweltbundesamt gefördert und von Universität Göttingen, Albrecht-von-Haller-Institut für Pflanzenwissenschaften, Abteilung für Palynologie und Klimadynamik durchgeführt. This project focuses on the long-term stability (or otherwise) of vegetation, based on a series of multi-proxy records in southern South America. We will build a network of sites suitable for high-resolution reconstructions of changes in vegetation since the Last Glacial Maximum, and use these to test a null hypothesis that changes in vegetation over the past 14,000 years are driven by internal dynamics rather than external forcing factors. The extent to which the null hypothesis can be falsified will reveal the degree to which we can expect to be able to predict how vegetation is affected by external events, including future climate change. The southern fringes of the South American landmass provide a rare opportunity to examine the development of moorland vegetation with sparse tree cover in a wet, cool temperate climate of the Southern Hemisphere. We present a record of changes in vegetation over the past 17,000 years, from a lake in extreme southern Chile (Isla Santa Inés, Magallanes region, 53°38.97S; 72°25.24W; Fontana, Bennett 2012: The Holocene), where human influence on vegetation is negligible. The western archipelago of Tierra del Fuego remained treeless for most of the Lateglacial period. Nothofagus may have survived the last glacial maximum at the eastern edge of the Magellan glaciers from where it spread southwestwards and established in the region at around 10,500 cal. yr BP. Nothofagus antarctica was likely the earlier colonizing tree in the western islands, followed shortly after by Nothofagus betuloides. At 9000 cal. yr BP moorland communities expanded at the expense of Nothofagus woodland. Simultaneously, Nothofagus species shifted to dominance of the evergreen Nothofagus betuloides and the Magellanic rain forest established in the region. Rapid and drastic vegetation changes occurred at 5200 cal. yr BP, after the Mt Burney MB2 eruption, including the expansion and establishment of Pilgerodendron uviferum and the development of mixed Nothofagus-Pilgerodendron-Drimys woodland. Scattered populations of Nothofagus, as they occur today in westernmost Tierra del Fuego may be a good analogue for Nothofagus populations during the Lateglacial in eastern sites. Climate, dispersal barriers and/or fire disturbance may have played a role controlling the postglacial spread of Nothofagus. Climate change during the Lateglacial and early Holocene was a prerequisite for the expansion of Nothofagus populations and may have controlled it at many sites in Tierra del Fuego. The delayed arrival at the site, with respect to the Holocene warming, may be due to dispersal barriers and/or fire disturbance at eastern sites, reducing the size of the source populations. The retreat of Nothofagus woodland after 9000 cal. yr BP may be due to competitive interactions with bog communities. Volcanic disturbance had a positive influence on the expansion of Pilgerodendron uviferum and facilitated the development of mixed Nothofagus-Pilgerodendron-Drimys woodland.
Das Projekt "Trees outside forest: Assessment" wird vom Umweltbundesamt gefördert und von Universität Göttingen, Burckhardt-Institut, Abteilung Waldinventur und Fernerkundung durchgeführt. Tree resources outside the forest (TOF) serve a number of ecological and socio-economic functions, similar in principle, but different in extent to the functions of forest. This resource is not yet fully recognized in natural resources assessments, particularly on a regional level. Many people in particular in the Tropics depend directly on this resource. For TOF sustainability, politics and management options must be developed and implemented. It means that good information about the assessment of this resource must be available. In this project, options of TOF assessment and mapping on a regional basis will be developed based in the results of earlier studies of the TROF project (EU- INCO DC Program. Contract No ERBIC18 CT98 0323) and others research projects experiences in Latin America. Objectives: To develop an approach to the TOF assessment and mapping on a regional basis.
Das Projekt "DEVOTES: Innovative Tools for Understanding and Assessing Good Environmental Status (GES) of Marine Waters ('The Ocean for Tomorrow')" wird vom Umweltbundesamt gefördert und von Fundacion AZTI,AZTI Fundazioa durchgeführt. The objectives are to: (i) improve our understanding of human activities impacts (cumulative, synergistic, antagonistic) and variations due to climate change on marine biodiversity, using long-term series (pelagic and benthic). This objective will identify the barriers and bottlenecks (socio-economic and legislative) that prevent the GES being achieved (ii) test the indicators proposed by the EC, and develop new ones for assessment at species, habitats and ecosystems level, for the status classification of marine waters, integrating the indicators into a unified assessment of the biodiversity and the cost-effective implementation of the indicators (i.e. by defining monitoring and assessment strategies). This objective will allow for the adaptive management including (a) strategies & measures, (b) the role of industry and relevant stakeholders (including non-EU countries), and (c) provide an economic assessment of the consequences of the management practices proposed. It will build on the extensive work carried out by the Regional Seas Conventions (RSC) and Water Framework Directive, in which most of the partners have been involved (iii) develop/test/validate innovative integrative modelling tools to further strengthen our understanding of ecosystem and biodiversity changes (space & time); such tools can be used by statutory bodies, SMEs and marine research institutes to monitor biodiversity, applying both empirical and automatic data acquisition. This objective will demonstrate the utility of innovative monitoring systems capable of efficiently providing data on a range of parameters (including those from non-EU countries), used as indicators of GES, and for the integration of the information into a unique assessment The consortium has 23 partners, including 4 SMEs (close to 17Prozent of the requested budget) and 2 non-EU partners (Ukraine & Saudi Arabia). Moreover, an Advisory Board (RSC & scientific international scientists) has been designed,to ensure a good relationship with stakeholders.
Das Projekt "PUMAS: Planning Sustainable regional-Urban Mobility in the Alpine Space" wird vom Umweltbundesamt gefördert und von Münchner Verkehrs- und Tarifverbund Gesellschaft mit beschränkter Haftung durchgeführt. Alpine Space cities face common urban mobility challenges which call for innovative and cost-effective mobility solutions. These challenges are: - limited public/ private budget for transport infrastructure; - excessive private car-based traffic in cities; - large amounts of fragmented goods delivery schemes contributing to congestion; - rising CO2 and noise, deteriorating air quality and adverse health impacts; - lack of/ inefficient institutional cooperation for long term solutions; - poor recognition of interdependencies between cities and neighbouring regions; - absence of an integrated planning approach to address mobility/ urban development/ land use planning. The Alpine Space is a region with continued growth, including increased passenger and freight transport. It suffers both from large volumes of cross-Alpine and seasonal traffic as well as sprawl from its cities to the countryside. It coordinates the development of the Sustainable regional-Urban Mobility Planning (SUMP) concept which the EC strongly promotes and, in its 2011 Transport White Paper, even suggests as a mandatory approach. Sustainable Urban Mobility Planning (SUMP) has the following characteristics: - active involvement of all stakeholders throughout the planning process; -commitment to sustainability, i.e. balancing social equity, environmental quality and economic development; - looking beyond the borders through an integrated approach between policy sectors, cooperation between authority levels and coordination across neighbouring authorities; - focus on achieving ambitious, measurable targets; - targeting cost internalisation i.e. reviewing transport costs and benefits for society; - comprehensive method including all steps of the life cycle of policy making and implementation. The PUMAS Project aims to: - advance SUMP, which focuses on participation, integration, evaluation and cost internalisation as a new paradigm in mobility planning; - develop, implement and evaluate 7 pilots using SUMP methods and tools; - generate best practice and lessons for others in the AS and beyond; - improve the awareness, exchange, coordination and development of regional-urban mobility plans (freight and passenger) through an innovative communication platform; - create the Alpine Space community and the National and Alpine Reference Point for SUMP in Slovenia, thus guaranteeing sustainability beyond the lifetime of the project. The Alpine Space Programme is the EU transnational cooperation programme for the Alps. Partners from the seven Alpine countries work together to promote regional development in a sustainable way. The programme is jointly financed by the European Union, through the European Regional Development Fund (ERDF) and the Partner States taking part in the activities. The contribution of the project partners coming from the EU are co-funded by ERDF up to a rate of 76%. The remaining costs have to be covered by other public funds, depending on rules at national level.
Das Projekt "Predicting the complex coupling of chemistry and hydrodynamics in fluidised bed methanation reactors for SNG-production from wood (bioSNG - fundamentals of methanation)" wird vom Umweltbundesamt gefördert und von Paul Scherrer Institut, Forschungsbereich Allgemeine Energie durchgeführt. Synthetic natural gas from wood-How can the synthesis be optimised? The production of bio natural gas as a fuel and combustible made of biomass that is rich in lignin presents an interesting alternative to the use (combustion) of biomass purely as a source of energy. In this project, researchers examine how the chemical reactions, the mass transfer and the fluid dynamics in fluidised bed reactors mutually influence each other. In experiments, they check whether the reactor simulation mirrors the actual processes precisely enough. This is important for optimising processes for the production of bio natural gas with the help of simulations. Background Woody biomass containing lignin, such as wood and straw, can so far only be transformed into a combustible product gas via thermochemical processes such as gasification. From the wood gas thereby gained, a synthetic natural gas is made via fluid bed methanation. This so-called bio-SNG (synthetic natural gas) can be fed directly into the existing natural gas network and is available as a renewable and CO2-neutral substitute for conventional fossil natural gas and as fuel for natural gas vehicles. The fluid bed methanation, during which wood gas is transformed into methane, works well at the pilot scale, but further research is necessary before it can be implemented in larger production plants. Aim The goal of the experiments is to collect on a 160 kW pilot plant data of sufficiently good quality that will enable researchers to validate the computer models. These models are used to upscale the fluid bed methanation to the scale of commercial plants and to optimise processes. During the experiments, the researchers will vary temperature, pressure, gas flows and gas composition. For process optimisation, the researchers will measure the fluid dynamics, the axial temperature and the gas phase concentration profiles and will use a catalyst sampling system. Significance The computer modules validated via the measurements on the pilot plant enable researchers to derive meaningful model experiments in the perspective of the 'observing passenger'. In these experiments, a small amount of a catalyst is exposed to a periodically changing gas mixture, which is what happens to the catalyst when there is movement in the fluidised bed reactor. This innovative approach can be applied to all chemical reactors with moving solids.
Das Projekt "Arid Southern Levant: a joint environmental and human history for the Holocene, derived from new archives of climate change (Dead Sea edge, Jordan)" wird vom Umweltbundesamt gefördert und von Universität Bern, Departement Biologie, Institut für Pflanzenwissenschaften durchgeführt. This project proposes to explore the potential of sedimentary sequences from arid Southern Levant to record past environmental and climate changes that can be compared with the evolution of human societies during the Holocene. The Levant, crucible of history, actually possesses very few archives of past climate change in its most arid parts, which restricts the possibility to compare, on a regional scale, environmental variation and the evolution of human communities through time. The region is characterised by contrasted bioclimatic conditions, from Mediterranean-type to arid. Most of the known records of environmental change are located in the moister, Mediterranean zones of the region, where increased water availability permits the presence - or the better preservation - of high-resolution and continuous archives of past climates. However, the potential of the arid environments of the Southern Levant (roughly corresponding to modern Israel, Palestine, and Jordan) to harbour records of Holocene (last ca. 11,500 years) climate change, is far from being exploited to its full extend. Following the unique discovery of Holocene organic, peat-like deposits in the rain-shadow of the Dead Sea area in Jordan, this project proposes to investigate the potential of this currently arid region to record past environmental and climate change. The organic sequences present in the mountain slopes East of the Dead Sea have been shown to contain very good pollen information. Results from a preliminary pollen study provided in particular evidence for the periodic extension of Mediterranean-type forest vegetation, from the upper Mediterranean plateaus down to the study area. These organic sequences can be further exploited to generate more precisely dated (mainly through radiocarbon techniques) and higher-resolution records of climate and environmental change for the Holocene. Pollen data will be complemented by a series of other proxies: charcoal studies indicating recurrent fires, spores and fungi revealing past grazing activities, diatom assemblages showing changes in the water quality, increased detrital content marking periods of enhanced erosion. All these results can then be integrated into dynamic models of local environmental changes and vegetation response. Furthermore, the same area contains multiple sequences of spring carbonates (tufa / travertine) waiting to be studied. The stable isotopic (oxygen and carbon) composition of spring carbonates can provide a good record of past climate change, as it registers variations in environmental factors such as temperature, parent-water composition (itself related to the source and amount of rainfall), and evaporation. The presence of carbonate sequences near organic sequences on the edge of the Dead Sea, offers an unprecedented occasion to directly compare the isotopic variations of carbonate series with environmental variations recorded in the peaty archives.
