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
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).
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.
Eine hohe Resistenz gegen Bodenpathogene, gute Standortanpassung und Veredlungsaffinität sind die entscheidenden Merkmale von Unterlagen. Bei der Pathogenresistenz ist bei Reben die Widerstandsfähigkeit gegen die Reblaus Daktulosphaira vitifoiae essentiell, da die europäische Kulturrebe Vitis vinifera L über keinerlei Resistenzen verfügt und nur an wenigen Standorten ein wurzelechter Anbau möglich ist. Klimaveränderungen erfordern neue Unterlagen mit hoher Reblausfestigkeit und besserer Standortanpassung. Aufgrund der derzeitigen Szenarien werden sowohl Trockenresistenz als auch Toleranz gegen hohe Kalkgehalte insbesondere in Verbindung mit hohem Bodenwassergehalte zukünftig von Bedeutung sein. Hierfür werden entsprechende Kreuzungen vorgenommen, die Sämlinge aufgezogen, auf ihre Reblausfestigkeit getestet und anschießend Prüfungen der Wurzelungs- und Veredlungsfähigkeit vorgenommen. Anschließend wird die Witterungs- und Bodenanpassung der Zuchtstämme insbesondere auf Trocken- und Kalkstandorten untersucht. Ziel ist die Entwicklung verschiedener Unteralgen, die eine vollständige Reblausresistenz mit hohen Trockenheits- und/oder Kalktoleranz kombinieren.
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.
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.
Objective: The strategic objective of the proposed project is to remove the knowledge barriers against the installation of Hybrid Renewable Energy Systems and the creation of mini-grids based on renewables. Ultimate objective of the project is to develop, combine, install, test and assess (technically and socially) the performance of low-cost pilot hybrid Renewable Energy (RE) systems in remote areas of the Mediterranean, which are not yet grid-connected. The hybrid systems will be consisted of photovoltaics, small wind generators, hydrogen subsystems and they will be installed in selected areas of the MPC countries to set-up and provide energy and associated services thus aid to the increase of the standard of living of these rural communities. The systems will be configured and sized after taking into account the local conditions. Three hybrid systems will be installed in remote rural areas of Egypt, Morocco and Tunisia. The systems should fulfil criteria as modularity, robustness, and simplicity in use and also require very low maintenance. Additional considerations for the technologies selection and implementation regard the possibility of systems standardisation and replication. Furthermore, the local installations will serve as good practice, accelerate local skill development, and promote and encourage international partnerships amongst all relevant stakeholders, such as research, financial, and regulatory institutions, industry and service companies, in particular SMEs, local representatives and social players. By setting-up the afore mentioned three pilot installations in three MPC the proposed research will bring a significant contribution for creating sustainable structures with a decent living quality in the rural environments of the MPC by developing highly innovative hybrid RE installations based on the availability of local renewable energy sources and the local social conditions and needs.
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.
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.
Understanding the drivers behind the loss of biodiversity currently observed is of major importance in the context of the global change discussion. For studies of biodiversity at broad spatial scales, satellite remote sensing is the premier source of information, as it is uniquely capable of covering large areas of the Earth at high temporal resolution. The underlying assumption is that satellite-derived geophysical surface parameters, such as vegetation greenness, are related to biodiversity. For that purpose, concepts such as the Dynamic Habitat Index (DHI) were recently developed. The DHI combines information on the overall greenness, the base level of vegetation cover, and vegetation seasonality at a certain location. By comparing the annual DHI with a long term mean, areas undergoing disturbances or recovery events can be delineated, which are indicative of changes in species composition and diversity. The concept of the DHI was developed for data obtained from the Moderate Resolution Imaging Spectroradiometer (MODIS) post-2000. However, for climate change impact studies a longer time series is desirable. The only sensor system suitable for such applications is the Advanced Very High Resolution Radiometer (AVHRR), which has been in orbit on various platforms since the early 1980ies. The purpose of this project was to develop a methodology to derive long term information on habitat conditions at continental scales based on historical satellite data. In particular, the goal was to adopt the principle of the DHI as developed for the MODIS sensor to an AVHRR archive at 1 km spatial resolution over Canada and to analyze long term variations in the DHI. In a first project phase, an AVHRR data set of vegetation greenness, generated in the framework of the project, was validated against the reference MODIS product. The results demonstrated a very good agreement between both data sets for a wide range of vegetation types and on various spatial and temporal scales. A historical baseline of habitat conditions post-1987 based on the DHI was subsequently generated based on the long term AVHRR data. The analysis of the DHI showed that certain areas, particularly northern parts of the Province of Quebec as well as southwestern Canada, experienced significant changes over the past two decades, which may have had significant impacts on species diversity and abundance in these areas. In the future, the methods developed in the framework of this project may be used to obtain information on long term variations in habitat conditions in areas covered by other historical satellite archives, e.g., for Europe based on an AVHRR archive hosted at the University of Bern.
