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.
MORSE was a joint European project, carried out by six partner institutions in France, Great Britain, and Germany. It was financially supported by the Commission of the European Community as a part of the Marine Science and Technology (MAST) program under contract no. MAS3-CT95-0027. The objective of the project was to gain an understanding of the physical processes involved in radar signatures of internal waves using laboratory tank, airborne radar, and satellite imagery. To achieve the ultimate goal, independent numerical models are needed which are capable of predicting radar backscattering for all radar bands, extracting ocean surface characteristics at high spatial resolution, predicting internal wave fields in time and space, and inverting radar signatures into geophysical parameters. Existing models were not sufficiently reliable to produce quantitative results in order to retrieve the three-dimensional structure of the ocean's hydrodynamic processes. Progress in the understanding and mathematical description of different processes and increasing capacity of modern computers opens doors towards much more detailed, comprehensive models. The activities of the Satellite Oceanography group of the University of Hamburg within the framework of MORSE focused on theoretical considerations regarding the hydrodynamic modulation of ocean waves by spatially varying current fields over internal waves and the radar imaging of the resulting roughness variations. This research was based on our advanced radar imaging model which describes the modulation of the complete two-dimensional ocean wave spectrum according to wave-current interaction theory and the backscattered radar signal by a composite surface model. In addition, the Satellite Oceanography group has wide experience regarding the analysis of radar signatures of internal waves. A large number of ERS-1 / ERS-2 SAR images of internal waves in the Strait of Gibraltar and in the Strait of Messina was analyzed. Furthermore, numerical hydrodynamical models were developed, which are capable of describing the generation and propagation of internal tides and their disintegration into internal solitary waves. The MORSE project has provided an opportunity to exploit and extend the knowledge obtained in previous remote sensing projects and to calibrate and validate the corresponding numerical models.
The 2nd Conference in the series of 'Integrative Approaches Towards Sustainability' is a response to the request of participants of the first conference held in Latvia March 26-29, 2003 (http://home.lanet.lv/ asi/). An impressive forum of excellent key-note speakers was challenged by an ambitious audience of young researchers at the 1st Conference proceedings of which contain 600 pages. The Baltic Rim, a recognised leader in integrated treatment of environmental, social, and economic problems of sustainable development (SD), is facing the challenge of full acceptance of the Baltic Countries and Poland to this worldclass club. The 2nd Conference aims to strengthen the integration of the region's RTD community and promotion of sharing its knowledge and expertise internally, across Europe (including the Mediterranean and Black Sea regions) and worldwide by inviting distinguished researchers to discuss the goals defined by the EU Council in Gothenburg, sciencebased thresholds of sustainability and limits with focus on the Baltic Rim, the corporate responsibility for SD in regional decision making, to share knowledge and expertise with particular focus on agriculture, forestry, education, and universitymunicipality partnership in basic and advanced fields of SD; to train the young researchers of the region and regions of Mediterranean and Black Sea. The 2nd Conference will contribute to creation of a 'critical mass' of human potential for SD in the region and Europe. The Conference tasks will be implemented by an appropriate Agenda and composition of participant list. It is essential for the region to organise a high level conference in a new member state on the East coast of the Baltic Sea in order to address senior researchers, to train the young ones from the Baltic countries and Poland and to encourage them to take the opportunities offered by the ERA and the EC 6th FP. The work under the project consists of 6 Work packages.
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.
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.

Context: With increasing global change pressures, and due to existing limitations, and un-sustainability factors and risks of conventional urban water management (UWM), cities experience difficulties in efficiently managing the ever scarcer water resources, their uses/services, and their after-use disposal, without creating environmental, social and/or economic damage. In order to meet these challenges, SWITCH calls for a paradigm shift in UWM. There is a need to convert adhoc actions (problem/incident driven) into a coherent and consolidated approach (sustainability driven). This calls for an IP Approach. Research conceptSWITCH therefore proposes an action research project which has as a main objective: The development, application and demonstration of a range of tested scientific, technological and socio-economic solutions and approaches that contribute to the achievement of sustainable and effective UWM schemes in 'The City of the future'.The project will be implemented by different combinations of consortium partners, along the lines of seven complementary and interactive themes. The research approach is innovative for the combination of: action research: address problems through innovation based upon involvement of users.learning alliances: to link up stakeholders to interact productively and to create win-win solutions along the water chain; multiple-way learning: European cities learn from each other and from developing countries, and vice versa.multiple-level or integrated approach: to consider the urban water system and its components (city level) in relation to its impacts on, and dependency of, the natural environment in the river basin (river basin level), and in relation to Global Change pressures (global level).Instruments and scopeAn IP with 30 partners, their resources, and a total budget of 25,191,396 EURO including budget for demonstration activities in 9 Cities in Europe and developing countries. Prime Contractor: UNESCO - Institute for Water Education, Delf, Netherlands.
The overall goal of the GEOMON project is to sustain and analyze European ground-based observations of atmospheric composition, complementary with satellite measurements, in order to quantify and understand the ongoing changes. GEOMON is a first step to build a future integrated pan-European Atmospheric Observing System dealing with systematic observations of long-lived greenhouse gases, reactive gases, aerosols, and stratospheric ozone. This will lay the foundations for a European contribution to GEOSS and optimize the European strategy of environmental monitoring in the field of atmospheric composition observations. Specifically, we will unify and harmonize the main Europeans networks of surface and aircraft-based measurements of atmospheric composition parameters and integrate these measurements with those of satellites. The access to data and data-products will be coordinated at a common data centre for more efficient use. GEOMon will support data gathering at existing networks if necessary, rescue and compile existing ground-based data, and develop new methodologies to use these data for satellite validation and interpretation.. In addition, GEOMON will enable innovative ground-based measurements complementary to satellites, made by upward looking ground based remote sensing instruments Max-DOAS, FTIR, and LIDAR and by systematic measurement programmes of upper-tropospheric composition using passenger aircrafts CARIBIC and MOZAIC. These data will serve to reduce biases and random errors in satellite observations and facilitate interpretation of the columnar measurements in combination with surface data. This will result in a significant improvement in the use of existing and future satellite data. Common techniques and modelling tools will be used in order to add value to the GEOMON data observations, to facilitate their use in satellite validation and help design an optimal network.

The project aims at supporting the implementation of the proposed Directive of the European Parliament and of the Council on the management of waste from the extractive industries 2003/0107. The Directive was prepared following several major accidents with a serious impact on the environment, and it has the purpose of ensuring a safer management of the mining waste facilities, so that such accidents will not occur in the future. This project addresses particularly Article 9, which provides for the classification of waste facilities with respect to the possible consequences of an accident, and respectively the Annex II: Characterisation of mining waste and Annex III: Criteria for the classification of waste facilities. The activities of the project are divided into four major work packages as follows: - Preparation of a Methodology for the Characterisation of Mining Waste - Elaboration of a Risk Assessment Methodology for the Classification of Mining Waste Facilities, including Old/Abandoned Mining Waste Facilities - Review of Techniques for the Prevention and Abatement of Pollution Generated by Mining Wastes - Development of a Decision Support Tool for Minimising the Impact of the Mining Industry on the Environment. The Consortium co-ordinated by BIUTEC, Austria, includes universities, research institutes, NGOs and implementing authorities from 8 European countries, both Members of the EU and accession countries. The experts team is highly qualified and has many years of experience and research in this area, so that the best outputs can be obtained. The project will build on the results of other projects carried out in this field, and will relate closely to on-going projects, so that there is no overlap in our activities. In order to provide an effective tool for the potential beneficiaries, the project team will consult with representatives of the stakeholders before the final versions of the outputs are publicly made available on the project web-site.
Article 16 of the Water Framework Directive (WFD, Directive 2000/60/EC) lays down the Community Strategy for the establishment of harmonised quality standards and emission controls for the priority substances and other substances posing a significant risk to, or via, the aquatic environment. In order to achieve the protection objectives of the WFD, the Commission shall (i) submit proposals for quality standards applicable to the concentrations of the priority substances in surface water, sediment or biota, and (ii) identify the appropriate cost-effective and proportionate level and combination of product and process controls for both point and diffuse sources. Proposals for environmental quality standards and emission controls for point sources shall be submitted within 2 years of the inclusion of the substance concerned on the list of priority substances (European Parliament and Council Decision No. 2455/2001/EC), i.e. in December 2003. This study is part of the preparatory work of the Commission and its overall objectives are: - The development and description of a concept which enables the European Commission to submit proposals for quality standards applicable to the concentrations of the priority substances of the Water Framework Directive (2000/60/EC) and those substances not on the priority list but regulated in the 'daughter directives' of Directive 76/464/EEC (on pollution caused by certain dangerous substances discharged into the aquatic environment of the Community) in water, sediment and biota, as required by Articles 16(7) and 16(10) of the Water Framework Directive. - Elaboration of proposals for quality standards for the priority substances of the Water Framework Directive and recommended values for other substances of concern (see footnote 1) with regard to surface water, sediment, biota, and human health as objectives of protection. Conclusions: The elaboration of quality standards with the developed methodological framework clearly showed that the proposed approach is applicable for the derivation of specific quality standards addressing the particular objectives of protection as well as for the identification of the overall quality standard that finally may be imposed to safeguard the entire set of objectives of protection. Also, with regard to the effort required to work with the concept, it can be considered as economic. This is attributable to the fact that despite the comprehensive consideration of all relevant routes of exposure and objectives of protection the different quality standards for the specific objectives are normally only derived if certain pre-defined trigger values are exceeded. This avoids the assessment of irrelevant exposure routes and the calculation of unnecessary standards. Problems encountered during the elaboration of the standards were in general not attributable to the suggested methodological framework but mostly to the limited availability of data or to the limitations of the available data.
Im Rahmen dieses Projektes wurde die Situation von Reststoffen aus der Papierindustrie europaweit durch eine umfangreiche Datenaufnahme abgeschätzt. Hierbei zeigte sich, dass in Frankreich und Deutschland die größten Mengen an Papierreststoffen entstehen und die Entsorgungsvarainten am vielfältigsten sind. In den anderen europäischen Ländern fallen wesentlich weniger Reststoffe an, zu meist durch das Fehlen einer Abwasserreinigungsanlage oder durch eine niedrige Altpapiereinsatzquote. Die Reststoffe aus diesen Ländern werden überwiegend auf einer Deponie entsorgt. In einem weiteren Teil des Projektes wurde die stoffliche Verwertung durch Kompostierung von Papierreststoffen auf biochemische und mikrobiologische Parameter hin untersucht. Dabei wurde auch der potenzielle Abbau von chlorierten Phenolen betrachtet. Es zeigte sich, dass die chlorierten Phenole keine große Belastung für Papierreststoffe darstellen. Da im Gegensatz zu den chlorierten Phenolen die Menge an chlorierten organischen Substanzen (AOX) in Papierreststoffen sehr hoch ist, wurde das umweltchemische Verhalten von AOX-Substanzen durch Schüttelversuche in verschiedenen Lösungsmitteln und Lysimeterversuchen getestet. Die Ergebnisse zeigen, dass AOX-Substanzen sich nur in geringem Umfang durch eine Elution mit wässrigen Medien lösen lassen. Da die organischen Schadstoffe (gemessen als AOX) in Papierreststoffen besonders relevant sind, sollte versucht werden, mehr über die chemische Struktur (insbesondere das Molekulargewicht) dieser Substanzen herauszufinden. Dabei wurden die Methoden der Ultrafiltration und der Gelpermeationschromatographie eingesetzt. Die Ergebnisse zeigen eine hohen Anteil AOX-Substanzen im hochmolekularen Bereich, wobei die Struktur der Verbindungen stark vom anfallenden Reststofftyp abhängt. So konnte nachgeweisen werden, dass der Haupteil an AOX-Substanzen in den Deinkingreststoffen überwiegend aus chlorierten Druckfarben, insbesondere den gelben Pigmenten, besteht. Eine Substitution dieser Farbstoffe aus der Azofarbgruppe würde zu einer deutlichen Reduktion der AOX-Problematik führen.
