The project aims at achieving a better understanding of the processes that drive or limit the response of grassland systems in a world of increasing atmospheric pCO2. We will test the hypothesis that the previously shown increase in below-ground allocation of C under elevated pCO2 provides the necessary energy excess and will stimulate free-living N2 fixers in a low N grassland environment. The project thus aims at assessing the occurrence and importance of free-living N2 fixers under elevated pCO2 and identify the associated microbial communities involved in order to better understand ecosystems response and sustainability of grassland systems. This project had the last opportunity to obtain soil samples from a grassland ecosystem adapted to long-term (10 year) elevated atmospheric pCO2 as the Swiss FACE experiment. The project aims to identify the relevant components of free-living diazotrophs of the microbial community using 15N stable isotope - DNA probing.
Under the 2003 EU Greek presidency, cooperation with Balkan countries on environmental issues was identified as a priority of the EU/Balkan Action Plan. Large-scale co-operation is essential for effective action in the vulnerable Mediterranean and Black Sea coastal zones. During the last 50 years both areas suffered major changes; as semi-enclosed basins, both Seas are ultra-sensitive to anthropogenic stress and to climate change. An EU Presidency Conference on Sustainable Development in the Mediterranean/Black Sea (May 2003), revealed major gaps in management structures, scientific strategies and identified a diversity of environmental issues to be resolved through priority-focused RTD cooperation. Yet, while pressure on the resources of the two seas increases and the potential impact of climate change on coastal and deep-sea resources remains unknown, the two seas have never been jointly studied as systems of interacting basins and ecosystems. The proposal outlines collaboration and clustering schemes involving environmental, economic and scientific organisations in Mediterranean, Black Sea and other EU nations, in order to create synergies in networking and exchanges at several levels, addressing for the first time the system of interconnected basins as one, based on the integration of, both horizontally and vertically, natural scientists and economists. These will: 1) Create an international, interdisciplinary platform coordinating the region's scientific potential in order to prepare RTD projects, based on a Science Plan for the region, securing sustainable development; 2) Focus on natural and anthropogenic pressures exerted upon the functioning of the ecosystem; 3) Reinforce RTD capacity by setting up an environment/resource monitoring network in the light of existing observation networks of different scopes.

Recent events such as the Pakistan earthquake, Hurricane Katrina, the Indian Ocean tsunami and the European heat waves of 2003 reveal the vulnerability of societies to extreme events. The goal of this project is to strengthen prevention, mitigation and preparedness strategies in order to reduce the health, social and economic impacts of extreme events on communities. The objectives of the MICRODIS project are to strengthen the scientific and empirical foundation on the relationship between extreme events and their impacts; to develop and integrate knowledge, concepts, methods and databases towards a common global approach and to improve human resources and coping capacity in Asia and Europe through training and knowledge sharing. This integrated project involves 19 partners from Asia and Europe, including research, policy and ground roots institutions. The outputs will include an evidence-base on impacts, field methodologies and tools for data compilation, impact models, and integrated vulnerability assessments. It will also strengthen standardised data collection of extreme events and their impacts at local, regional and global levels.

The ARCHAIA project aims at implementing two training seminars on cultural heritage based on an innovative integrated perspective deriving both from the human and the natural sciences. The seminars address 90 post-graduate students, scholars and professionals of different backgrounds. Starting from the need of disseminating the results of 9 funded EU research projects and COST actions, we aim at presenting these within an innovative framework, i.e. a global approach towards planning and management of archaeological parks starting from the very first steps of field research and going through the characterisation of the materials retrieved and topographical studies in order to mould every bit of historical information within a coherent project, properly displayed for the public. Through an innovative didactic methodology, innovative scientific contents will be disseminated. Dealing with the initial program of archaeological research in the field, integrated with techniques of archeobiological and geoarchaeological investigation, our final goal is to supply the participants with the guidelines for moulding research strategies and managing archaeological sites, in order to be able to publicly display the historical content derived from research results and effectively proceed to the protection of the cultural heritage. One training seminar will be in Copenhagen and another one in Bologna. Five key topics have been selected: Topic 1 concerns Topography, surveying and landscape archaeology, Topic 2 Archaeological research and restoration of monuments, Topic 3 Material culture characterization, Topic 4 Anthropology and environment and Topic 5 Data processing and public presentation. The dissemination of the lectures presented through a monograph and multimedia products will also supply guidelines for integrated protocols on the management of archaeological sites, set in their landscape, within a global perspective.
Objective: New process route for lightweight, unbreakable and economically feasible solar panels on the basis of amorphous silicon. Results: From a number of canditates enamel-coated steel sheet as substrate and an organic barrier as protective layer was chosen as an alternative to the dual glass panels. Criteria were vacuum compatibility, surface rougness and insulating properties. This concept requires that the production order of the thin film solar cell is reversed into back electrode, active stack, front transparent electrode. Inverted processes and low temperature processes were investigated in parallel. Protection against damage due to permeating water was reduced with an improved organic barrier coating. Also, less vulnerable back electrode materials were studied. Fluorine doped tin oxide, tin-doped indiumoxide and aluminium-doped zinc oxide were studied. However, the best and most economical results were optained with ITO. For monolithic integration mechanical masking and laser scribing were investigated. Mechanical masking failed due to the uneveness of the enamel surface. Laser scribing is possible due to the diminished power need with each consecutive layer. Some concepts for better light capture (texturing, optical coatings) were investigated. Based on the inverted process route small scale and full scale panels were manufactured and tested. Ultimately, the full scale failed due to the built-up of stress which caused delamination and could not sufficiently be reduced. The panel costs of the new route proved very similar to the existing product, but required an additional investment in vacuum deposition equipment. Surprisingly, ITO with recycling proved to be the most cost effective transparent electrode material.
An einer ausgewählten Tankstelle in Luxemburg wurde mit dem VACONOVENT®-System eine neuartige Variante im Vergleich zu den bislang eingesetzten Gasrückführungssystemen erprobt. Die Ermittlung der Emissionen bei der Betankung von Kraftfahrzeugen mit Ottokraftstoff erfolgte durch drei verschiedene Messinstitute bei drei unterschiedlichen Betriebszuständen der Gasrückführungssysteme: Rückführrate 0, 100 und 150 Prozent. Bei allen drei Messkampagnen ist der Unterschied in den Emissionen bei wirksamer Gasrückführung zur abgeschalteten Gasrückführung klar erkennbar. Der Einfluss des verbesserten Rückführwirkungsgrades bei Rückführraten bis zu 150 Prozent auf die Gesamtemissionen der Tankstelle konnte aufgrund verschiedener Randbedingungen nicht eindeutig festgestellt werden.
In Vorbereitung des Langzeitmonitorings transgener Kulturpflanzen wurde die Variation ökologischer Parameter beim Anbau von Kartoffeln unter Praxisbedingungen im Land Brandenburg (2001-2003) analysiert. Ziel der Untersuchungen war es, im Rahmen einer Baseline-Studie ökologisch relevante Parameter der Agrarbiozönose 'Kartoffelfeld' zu analysieren und hinsichtlich ihrer Eignung für das Monitoring gentechnisch veränderter Kartoffeln zu bewerten. Die Studie konzentrierte sich auf die Untersuchung der boden- und pflanzenassoziierten Mikroflora, der Begleitfauna und -flora sowie auf die Abschätzung des Ausbreitungspotentials der Kartoffel. Daneben wurden zur Kennzeichnung der Versuchsbedingungen Standort- und Witterungsgrößen erfasst. Untersuchungsgrundlage waren jährlich 11 unterschiedlich bewirtschaftete Schläge (Ökologischer Landbau vs. Integrierter Pflanzenbau mittlerer und hoher Intensität), die sowohl in der Textur als auch in der organischen Bodensubstanz variierten, wenngleich ausschließlich für den Kartoffelanbau geeignete diluviale Standorte genutzt wurden. Somit lagen ähnliche, aber eindeutig differenzierte Ausgangsbedingungen vor. Teilthema 1: Auswahl und Charakterisierung der Untersuchungsstandorte. Teilthema 2: Charakterisierung der angebauten Kartoffelsorten. Teilthema 3: Analyse der Zusammensetzung bakterieller Gemeinschaften. Teilthema 4: Zusammenfassung der Kartoffelbegleitflora. Teilthema 5: Begleitfauna der Kartoffelbstände.
Working group 7 (Agriculture) under the European Climate Change Programme has so far mainly dealt with mitigation potentials of GHG. A thorough integrated economic and environmental assessment in the area of agriculture and sinks has not yet been carried out. In order to support the international negotiation process and for the development of good policies the Integrated Sink Enhancement Assessment (INSEA) project's objective is to develop an analytical tool to assess economic and environmental effects for enhancing carbon sinks in agriculture and forestry. The approach is centered on spatially explicit databases that will allow the calculation of 'cost-landscapes' taking on an engineering approach to integrated costs computation of additional sink enhancement measures and negative emission technologies. The various model structures will be applied to detailed European data sets and less detailed global data sets assessing the marginal abatement cost and long-term scenarios of sink enhancement measures. Concise policy conclusions from the modeling exercise will aim at supporting the implementation of the Kyoto Protocol commitments as well as post Kyoto negotiations. In the proposal we advocate a spatially explicit approach that is motivated by the fact that LULUCF activities are by their very nature spatial entities and aggregate non-spatial treatment could, according to our experience, lead to serious biases in the assessment. Furthermore, we propose not only a simple and easily tractable static and deterministic approach for cost calculations, but also more comprehensive, dynamic, and uncertainty (risk)-based treatments. We believe that such a multidimensional approach is necessary since ecosystems are more complicated and complex in their responses and therefore robustness and consistency across a variety of decision rules will guarantee sustainable management of this natural resource.
Many of the world's mountain ecosystems are moving along trajectories that couple high rates of environmental change with strong economic changes, whose collective effect may alter the ability of mountain regions to provide critical goods and services, both to mountain inhabitants and lowland communities. In order to address the environmental challenges facing the world's mountain regions in the 21st Century, we will develop an integrative research strategy for detecting signals of global environmental change in mountain environments, for defining the consequences of these changes for mountain regions as well as lowland areas dependent on mountain resources, and for facilitating the development of sustainable resource management regimes for mountain regions. Following a kick-off meeting, the details of the research strategy will be formulated through a series of product-oriented workshops dedicated to: 1) Long-term Monitoring, 2) Integrated Modelling, 3) Process Studies, and 4) Sustainable Development. The concepts developed in these Thematic Workshops will be revisited, refined and synthesised during a final Open Science Conference on Global Change in Mountain Regions. By gearing the research strategy toward implementation in mountain Biosphere Reserves, the project will take advantage of the existing UNESCO infrastructure and ongoing Global Change research in these areas. The structure of UNESCO mountain Biosphere Reserves provides ideal natural Global Change laboratories with core protected mountainous areas surrounded by lower-elevation buffer zones that are more strongly influenced by human activities. European scientific participation, capacity building and leadership will be promoted by adapting the research strategy for implementation in UNESCO's mountain Biosphere Reserves in both developed and developing countries. This will be achieved through the active participation of Biosphere Reserve managers in the development of the research strategy.
Differenzierung der Quellen- und Senkenfunktion des Bodens unter Berücksichtigung der Nutzungsgeschichte. Im Rahmen des CARBOEUROFLUX-Projekts wurden im Hainich (Thüringen) Kohlenstoff (C)- Speicherungsraten festgestellt, die der Vorstellung der Kohlendioxid-Neutralität von alten Wäldern widersprechen und die Frage nach deren Kyoto-Relevanz aufwerfen. Im Rahmen europäischer Projekte lässt sich allerdings nicht klären, wie diese hohen Speicherraten entstehen und wo C im System verbleibt. Wir vermuten, dass durch historischen C-Export, z.B. infolge von Streunutzung, die Böden im Hainich verarmten und die entleerten Speicher jetzt wieder aufgefüllt werden. Um das Ausmaß des nutzungsbedingten C-Exports abschätzen zu können, werden aus Schriftquellen Art und Umfang der Biomassenutzung in ihrer zeitlichen und örtlichen Entwicklung rekonstruiert. Zudem untersuchen wir, welche Anteile des C-Eintrages veratmet, gespeichert und über den Wasserpfad exportiert werden. Hierzu werden 13C und 14C- Isotopenverhältnisse an Bodengasen sowie gelöstem und festem Boden- C bestimmt. Unsere Untersuchungen zielen auf ein grundlegendes Verständnis der C-Speicherung im Jahresverlauf ab. Die Zusammenarbeit mit dem Kompetenzzentrum 'Dynamik Komplexer Geosysteme' und dem europäischen CARBOEUROPE Cluster wird die Doppelerhebung von Daten verhindern und deren gegenseitige Verfügbarkeit sicherstellen. Ziel der Arbeit ist es, den historischen Kohlenstoffexport insbesondere unter Berücksichtigung der forstlichen Nebennutzung abzuschätzen. Hierzu soll anhand von Literaturdaten einerseits die Vegetationsgeschichte geklärt werden. Andererseits soll der im Untersuchungsgebiet im Zuge der forstlichen und landwirtschaftlichen Nutzungen erfolgte Biomasseentzug nach Art und Umfang dokumentiert werden. Diese Arbeiten sind notwendig, um den Einfluss der Nutzungsgeschichte auf die Kohlenstoffspeicherung im Untersuchungsstandort abzuschätzen. Im Rahmen des Gesamtprojektes sollen zunächst Daten zur Entwicklung der Biomasse im Untersuchungsgebiet zusammengestellt werden. Eine weitere Aufgabe besteht darin, auf der Basis von Literaturstudien einen möglichen Vergleichsstandort mit unterschiedlicher Nutzungsgeschichte zu identifizieren.
