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).
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.
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).

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.
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.
In spite of a variety of efforts, tropical forests are still threatened by exploitation and conversion to agricultural land-use. Besides legal protection, sustainable management concepts are essential for stable conservation of these ecosystems. This project aims at identifying and optimizing the potentials for forest management for three different ecosystems (Dry Forest, Tropical Mountain Rain Forest, Paramo) along a height- and climate gradient in Southern Ecuador. Therefore, multiple and locally differentiated aspects of forest management have to be considered: the direct provision of goods (timber and non-timber forest products) as well as ecosystem services (carbon sequestration, water regulation), which are of increasing importance; moreover, the effects of forest management on biodiversity and the impacts of climate change on resilience indicators and the potential distribution of selected species with high potential for sustainable management or conservation should be investigated. First of all, the most important forest structure types and possible improvements of management alternatives have to be identified at the three sites for the assessment of different management concepts. The alternatives will be tested on experimental field plots and consequently monitored for their impacts on the locally most important criteria of forest management. A sound decision support tool will be developed, taking into account uncertainties with regard to input parameters and the relevance of different criteria of forest management. Therefore, Multi Criteria Decision Analysis will be used to generate locally adapted management concepts for the different ecosystems. Those concepts should be able to consider the multiple functions of forest management and will represent the forestry component in sustainable land-use models. The comprehensive studies will be carried out in close cooperation with other scientific teams from Germany and Ecuador as well as local institutions of relevance for forest management. The direct involvement of Ecuadorian students and young academics and the integration of the investigations in educational concepts will contribute to capacity building and local efforts for the enhancement of environmental competencies. Moreover, the experimental field plots will serve in parts as demonstration objects for the implementation of sustainable forest management concepts.
The fire blight disease caused by the bacterium Erwinia amylovora, is currently the major constraint for apple production in several European countries including Germany and Switzerland. In recent years several infections occurred which have led to costs in the tens of millions Euros. The antibiotic Streptomycin (Plantomycin®), which is the only effective plant protective agent, can only be applied under particular restrictions. Planting of fire blight resistant cultivars seems to be the most promising solution, which is environmental and producer friendly. Unfortunately, the available fire blight resistant apple cultivars are non-competitive on the market, because of their inferior fruit quality. The improvement of established cultivars like 'Golden Delicious' or 'Gala' using classical breeding strategies is impossible because apple is self-incompatible and heterozygous. Each offspring of a sexual cross between such a cultivar and a resistant genotype will be genetically different to each of the parents. Linkage drag coming from the resistant led often to a decrease in fruit quality. Several crosses with cultivars of good quality are necessary to remove most of the unwanted traits and the result will be a completely new cultivar. Breeding of such a new apple cultivar is time consuming and in the end it is not clear, whether the new cultivar will be accepted by consumers and growers or not. Under these premises, the introduction of a specific gene into a particular cultivar which already has all qualities necessary, except the trait in question, is attractive. The recombinant DNA-technology offers the most promising strategy to solve the problem of fire blight by using Malus own genes without the need to change the popular cultivars. The development of cisgenic plants seems to be a realistic and successful strategy. Cisgenic plants contain only genes, which originates from crossable species and not from outside of the primary genepool. They are therefore comparable to classical bred plants and expected to be acceptable by consumers and growers. The methodology to produce such a durable resistant cisgenic apple cultivar has already been established, but an apple fire blight resistance gene (or linked gene set) is still needed. Recently a strong Fieblight resistance has been identified on chromosome 3 of the apple hybrid Malus x robusta 5. This project focuses on the isolation of the gene(s) inducing the resistance of M. x robusta 5 and its cloning into the susceptible cultivar Gala. Furthermore the interaction of this (or these) genes products with gene products of the pathogen will be studied so to understand the interaction mechanisms and therefore evaluate the durability of the resistance.
Objective: The results of the project will improve and widen the potential for the integration of solar (PV) energy systems into existing buildings. Special attention will be paid architectural and aesthetic questions. Building integration of PV systems in most cases leads to a 'high tech' and 'modern' appearance of the building. This is caused by the typical window-like surface of most conventional PV modules. Regarding however that90Prozent of the building stock consists of longer existing, that means 'old fashioned' buildings, it is evident that anaesthetically satisfying building integration of PV needs a lot of good will and creativity from planners and architects. In many existing building integrated PV systems the modules contrast with the building and its surroundings. A European survey on the potential and needs for building integrated PV components and systems will identify the basis for the development of modules away from the glass / window-like appearance. In the project PV roof tiles, overhead glazing and facade elements based on CIS thin film technology will be developed and investigated which have a modified optical appearance for better adaptation to the building skin. One of the ideas is optical decoupling of substrate and cover glass. A complete roof tile system with thin film cells adapted to the visual appearance of conventional roof tiles and innovative connection and mounting will be developed. The work includes prototype fabrication and tests according to relevant standards and subsequent performance tests. Novel overhead glazing includes semitransparent thin film modules optimised for daylight transmission. The backside appearance will be modified in order to represent the visible inner part of the building skin. For overhead and insolating glazing an invisible interconnection and for PV roof tiles a low cost connector will be developed. Project results will be systems ready for industrial production.
The Kyoto Protocol as a substantial extension to the UN Framework Convention on Climate Change (UNFCCC) contains quantified, legally binding commitments to reduce greenhouse gas (GHG) emissions and allows emissions to be balanced by terrestrial biological carbon sinks. The Austrian target for the first commitment period (2008 2012) is a reduction of GHG emissions of 13% below those of 1990, the EU aims at a reduction of 8%. Due to further increased GHG emissions since 1990, an actual reduction target of 22% can be expected for Austria. The KP and its implementation rules provide for human induced net changes of domestic sinks in the land-use, land-use change and forestry (LULUCF) sector to be counted in the emission balance of Annex 1 countries (developed countries and economies in transition). With the so called flexible mechanisms the Kyoto Protocol designated three international mechanisms, including sink projects abroad and GHG emission trading, to increase flexibility and costeffectiveness in achieving GHG emission reductions in the first commitment period 2008-2012. Under the UNFCCC and the KP, parties must follow clearly defined GHG inventory and reporting obligations including the verifiable and transparent documentation of the LULUCF sector. The latter is very precisely specified by the recently published IPCC Good Practice Guidance (GPG) for LULUCF, which suspects that in most countries the existing land use and inventory systems are inadequate to meet all the land reporting requirements of the Kyoto Protocol. Remote Sensing is attributed a significant role for LULUCF reporting and verification by the IPCC GPG. Remote sensing can be applied to supplement missing elements of existing land use and forest inventory systems, or to deliver the basic LULUCF information and to estimate (via models) above ground biomass changes on the one hand, and/or as an independent verification/validation tool for land use/forest area changes and above ground biomass. The development of RS as an independent verification tool as done in NEOS-QUICK, based on a multi-sensor approach, integrating GIS and ground observations, nevertheless leaves room for flexible applications of the elaborated RS techniques in either of the above mentioned ways.
