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.
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
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.
The baking industry includes companies that make value added products including bread, buns, rolls, doughs, desserts, crusts, pastas, cookies, biscuits, crackers etc. that are either baked or frozen. The use of refrigeration technology has made a bakery's location independent of its customers, thereby broadening the geographic market potential and contributing to the growth of this sector. However, this development does have a cost. Bakeries are energy intensive, using large amounts of electricity and natural gas to operate the refrigeration system, compressed air system and ovens. These energy costs are rising and becoming a significant portion of the ingredient costs of baked goods. About 10Prozent of the total electrical and thermal energy consumption of all craft enterprises originates from the bakery sector. Accordingly there are many possibilities for energy reduction and therefore to permanently reduce the costs for the enterprises and thus to make a sustainable contribution to climate protection. Making changes in the energy use patterns of bakeries would be the fastest way to affect the energy profile of bread, because bakery is responsible for 70 and 80Prozent of the total energy consumption in conventional and organic bread production, respectively. Overall aim of the NanoBAK-Collaborative Project is the efficient energy management in the baking industry. Specific aim of this project is the development and demonstration of a novel marketable climatic chamber with an innovative, energy-saving nano-aerosol humidification system. Lab tests have shown that the energy consumption using ultrasonic humidification is significantly lower than for conventional humidification. The innovative ultrasonic humidification of the NanoBAK Project saves up to 50Prozent of energy compared to conventional humidifiers. Furthermore the quality of the bakery goods is of high value, so that the ultrasonic humidifier is profitable both energetically and qualitative.
Changes in European agricultural landscapes have gained on intensification in the second half of the last century. Among others, they are driven by global change phenomena such as climate change, demographic change and migration, increasing global bio-energy demands and changing human diets as well as by trade liberalisation, technological progress, and leakage effects of land use policy interventions. Farmers usually respond to such changes by adapting production and land use systems to efficiently utilize and manage their farm resource endowments. However, this process often leads to adverse impacts on the diversity of agricultural landscapes and environmental qualities. EU policies have been formulated as a reaction to singular or sectoral problems (e.g. the Common Agricultural Policy, the Water Framework Directive, the Nitrates Directive, NATURA2000), which are usually differently implemented among member states by using a variety of legislative or incentive based instruments. Consequently, more coordination among policies is required to minimize the trade-offs between different land use policy targets (i.e. land conservation versus boosting biomass production), and between private (adaptive) and societal (mitigative) land use benefits. Mitigation and adaptation are often separately analysed due to the nature of the problem i.e. mitigation is often considered as public good versus adaptation as private or club good. However, it is necessary to consider both in assessing the mutual benefits of cost-effective land uses and farm mitigation and adaptation measures, which mainly depend on spatial heterogeneity of natural and farming conditions. Consequently, it is important to consider bio-physical, ecological, and economic relationships in assessing the mitigative (public) and adaptive (private) potentials and trade-offs of alternative land uses and farm management measures.In this project we implement a data-model-policy fusion concept, which shall guarantee cost-effective mitigation and adaptation of farms and sustainable landscape and biodiversity developments in the context of climate, market, and policy instrument changes. The concept is applied to two case-study landscapes in the Mostviertel region in Austria and contains an integrated spatially explicit modelling framework to simulate the land use changes at field, farm, and landscape level as well as cost-effective farm mitigation and adaptation portfolios. The land use changes are assessed with farm economic, biodiversity, abiotic, and landscape indicators including GIS-modelling and field observations. Biodiversity effects are central in the integrated assessment acknowledging the roles of landscape structure and land use intensity. Geo-referenced land uses and land use attributes are a major interface in the data-model-policy fusion concept. The results will help farmers and regional stakeholders to identify best management practices for climate change mitigation and adaptation i
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.
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.
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.
Objective: Noise pollution is a major environmental problem within the EU. The social costs of traffic noise have been estimated to 0.4Prozent of total GDP. Road traffic is the dominant source, and also rail traffic noise is significant. At the same time, road and rail traffic are expected to steadily increase, and the source strength is not expected to significantly decrease within the near future. To reduce the outdoor traffic noise to a sufficiently low level for a good acoustic environment is a major challenge of high need. Here, we will focus on noise propagation abatement for the outdoor environment. Following the EU Directive on environmental noise, a series of major action have been taken in noise abatement, but the sustainability has rarely been paid attention. The main idea of our project is to optimize the use of green areas, green surfaces and other natural elements in combination with artificial elements in urban and rural environments for reducing the noise impact of road and rail traffic. The project offers a variety of powerful abatement strategies that will make a cost effective improvement by its combination of approaches concerning: ground and road surface treatments; trees, forests and tall vegetation; greening of buildings and other surfaces; and innovative barriers. The noise impact will be assessed in terms of sound levels (including spectra and time patterns) as well as perceived environment (including annoyance, well-being and other health related aspects). The main objectives of the project are: to show by full scale evaluation that the proposed abatement methods work; to deliver noise prediction methods applicable to the proposed abatements, which can also can be used in noise mapping software; to deliver assessment methods for the perceived noise environment; to deliver a good practice guide for the end-users; and to show the cost benefit, including the positive effect on urban air quality and CO2 neutrality, of the resulting noise abatement methods.

Global warming and land use influence the quality of rivers in Switzerland. Which influences have a negative effect on water quality? What must be undertaken to maintain good water quality? Background Global warming as well as the way in which land is used will have a significant influence on the quality of our watercourses in the coming decades. Due to global warming, the temperature in rivers will increase and the rate of flow will change. Agricultural, industrial or traffic uses add pollutants to the rivers. Nutrients, pollutants and fine sediments will increase or decrease in rivers. These changes affect water organisms and ecosystems, although, at this point in time, very little is known about these influences. Objectives and methods This project develops decision-making support that will make possible the assessment and minimization of negative effects on the ecological state of watercourses. For this purpose, various measures linked to the management of rivers and their surroundings will be examined. Three types of information will be combined: firstly, means of action will be compiled in collaboration with representatives of the authorities and associations from the area of the Mönchaltdorfer Aa and the Gürbe. Secondly, the various conditions of watercourses - e.g. with regard to fish health - will be evaluated. Using these results, the influence of the management measures can be assessed. This will also be done jointly with the various stakeholders. Thirdly, a model will be developed to describe the effect of measures on water quality and aquatic plants and animals. This model will look several decades into the future and will therefore be subject to significant uncertainties. Therefore, the project will show how such uncertainties can be taken into account when making decisions concerning management measures. Significance Using a comprehensive approach, all the important aspects of water quality will be examined. The project will show which risks may be of major concern in the future. The results will help to set the correct priorities when choosing measures for the protection of water quality in rivers.
