Impact of long-term exposure to elevated pCO2 on activity and populations of free living N2 fixing organisms in a temperate grassland system

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.

FP6-SUSTDEV, Sustainable Water management Improves Tomorrow's Cities'Health (SWITCH)

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.

FP6-POLICIES, ARCHAIA: Training Seminars on Research Planning, Conservation, Characterisation and Management in Archaeological Sites

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.

Sustainable sanitation system for low-income densely populated urban areas in Indonesia (Case study: Kali Rungkut Sub-District, Surabaya, East Java)

Waterborne sewage system has proven to be inappropriate to solve sanitation needs in developing countries. Approximately 90 percentt of city sewage in developing countries today is discharged untreated, polluting rivers, lakes and coastal areas (Winblad, 1997). With increasing population density and the resultant groundwater pollution, conventional decentralized disposal systems such as latrines and seepage pits are not viable alternatives either. Many cities are short of water and subject to critical environmental degradation (Niemczynowicz, 1996). Conventional sanitation technologies based on flush toilets, sewers, treatment and discharge cannot solve the problems in urban areas anymore. A sustainable sanitation and wastewater management system is urgently needed in order to address these issues. Ecological sanitation (Ecosan) is proposed as an alternative system to solve the following problems: lack of sanitation and water body contamination by pathogens from human waste. Ecosan does not only provide sanitation facilities for the people, but also seeks to protect public health, prevents water pollution and at the same time returns valuable nutrients to the soil so that it also helps to ensure food security and contributes to the objectives of sustainable development. The objective of this research is to search for a sustainable sanitation and human waste management system that is appropriate to be applied in poor income people living in densely populated urban areas in Indonesia. As Ecological Sanitation has not been applied in Indonesia before, this dissertation also aims to investigate its effectiveness and community acceptance in Indonesia. Two other existing systems are also studied as the comparison, which are the conventional septic tank system and the decentralized wastewater system (Dewats). All of these sanitation systems are assessed based on three sustainability criteria: economical, environmental and social.

FP6-POLICIES, Horizontal Standards on Hygienic parameters for Implementation of EU Directives on Sludge, Soil and Treated Bio-waste (HORIZONTAL-HYG)

The working documents on revision of the Sewage Sludge Directive (86/278/EEC) on Biowaste and the Soil Protection Communication call for standards on sampling and analysis of sludge, treated biowastes and soils. The European Directives are intended to prevent unacceptable release of contaminants, impairment of soil function, or exposure to pathogens, and to protect crops, human and animal health, the quality of water and the wider environment when sludges and treated biowastes are used on land. The EU animal by-product regulations are fixing microbiological threshold values, for which microbiological methods of analysis are needed. The European Commission wishes to cite European (CEN) standards in order that there is harmonised application of the directives and that reports from Member States (MS) can be compared. This project to develop standards for hygienic parameters in sludge, soil and biowaste, presented under the name 'HORIZONTAL-HYG', will be carried out under the umbrella of the main project HORIZONTAL 'Development of horizontal standards for soil, sludge and biowaste'. This ensures full integration in the CEN system through BT Task Force 151 specially set up in support of this project as well as direct supervision by DG ENV and MS, which form the Steering Committee of HORIZONTAL. Preparation of HORIZONTAL-HYG was taken in a full agreement with the DG ENV, DG JRC and the MS already contributing to HORIZONTAL. HORIZONTAL-HYG's objective is to produce standardised methods for sampling and hygienic microbiological parameters, as Salmonella spp, Escherichia coli, Clostridium perfringens, Ascaris ova in sludges, treated biowastes and soils written in CEN format. Validation of the methods is an essential part of the development as it quantifies performance in terms of repeatability and reproducibility. The consortium is well connected in CEN and ISO and thus provides an excellent basis for implementation of the deliverables.

FP5-IST, Computerised Video Camera Image Analysis for Monitoring Pollution in Water (BLUEWATER)

The Research Group Satellite Oceanography of the Institute of Oceanography, University of Hamburg, is participating in the joint international project BLUEWATER, a 30-months investigation of marine pollution monitoring using video camera systems. Bluewater is partially funded by the European Commission's Information Society Technologies Programme, project number IST-1999-10388. Project Objectives: BLUEWATER uses video cameras and image analysis for cionstant monitoring/early warning of pollution in water. Anthropogenic/biogenic slicks (from hyydrocarbons, fish oil, algal bloom, bacteria etc.) löeave surface signatures by damping of wave motions which the system will detect in concentrations of 1 to 8 mg/m2. Suspended solids damp waves detectable at 100 mg/litre. The major random cause of high pesticide & heavy metal levels (5 to 7 orders of magnitude) is from accumulation by biogenic slicks, detectable as above. Pollutant presence detected by comparing wavescape with normalö water surface for similar conditions (wind, rain, tide, depth etc.) Experimental data gathered in tanks and open sea used to build image analysis algorithms. The project will offer sophisticated HCI and prediction and analysis functionality. Installations linked to riggedised display terminals on which web pages/video run for publicity/information.

FP6-POLICIES, Safeguarded Cultural Heritage-Understanding and Viability for the Enlarged Europe (SAUVEUR)

The proposal suggests the organisation of the 7th EC Conference on Cultural Heritage Research in Prague, in 2006. The scope of the project stems from the SSP priorities, and the conference aims at the consolidation and impact assessment of results achieved in EU research projects related to movable and immovable cultural heritage, with a special focus on exploitation and spin-off of cultural heritage research results and testing of the acceptability of new sustainability approaches and new technologies by the user community, SMEs, owners, managers and restorers or conservationists of the cultural heritage. The Prague conference has been designed to further define the role of Europes cultural heritage research within the international context and as part of international cooperation, to explore the possibilities for SMEs in contributing to competitiveness and job creation, to define the support of cultural heritage research to policy needs and to contribute to the 7th Framework Programme establishment through support of the European Construction Technology Platform concept and research infrastructure development. The wider public will be addressed by means of special accompanying events, too, in order to ensure feedback and response from non-professional stakeholders. The Conference will consist of sessions dealing with political exploitation and public dissemination of cultural heritage research, the international role of European cultural heritage research, poster displays and verbal presentations of policy impact assessment, research infrastructure achievements, innovative applications and new ideas, as well as coordination of national education and research into cultural heritage issues. Public and professional awareness shall be increased by special demonstration and post-conference activities, including publication of the Conference Proceedings. The results and continuing activities will be supported by IT tools and follow-up working groups, after the event.

Beitrag der arbuskulären Mykorrhiza (AM) im ökologischen Landbau zur Förderung der Bodenfruchtbarkeit unter der Berücksichtigung verschiedener acker- und pflanzenbaulicher Massnahmen und der Dauer der ökologischen Bewirtschaftung

Der oekologische Landbau laesst aufgrund der systemeigenen spezifischen Fruchtfolgen, Duengemassnahmen und Bodenbearbeitung positive Auswirkungen auf die Entwicklung d arbuskulaeren Mykorrhiza und die Kolonisierung der Kulturpflanzen erwarten. Diese positiven Auswirkungen wurden in vergleichenden Untersuchungen ueber die Auswirkungen einzelner Kulturmassnahmen auf die arbuskulaere Mykorrhiza in konventionell und nachhaltig bewirtschafteten Standorten nachgewiesen. Wenn in der Zukunft eine Verringerung des Eintrages an Agrochemikalien in die Kulturlandschaften angestrebt wird, muss der Bedeutung der arbuskulaeren Mykorrhiza eine hoehere Aufmerksamkeit gewidmet werden. Um die positiven Auswirkungen der arbuskulaeren Mykorrhiza in landwirtschaftlichen Produktionssystemen optimal zu nutzen, ist die Verwendung von geeigneten Duengemitteln in adaequater Menge, ein groesstmoeglicher Verzicht auf einen Pestizideinsatz und eine entsprechende Fruchtfolgegestaltung mit einem Minimum an Bodenbearbeitung und der Vermeidung von Schwarzbrache sicherzustellen. Ziel dieses Projektes ist die Optimierung der Lebensbedingungen und Leistungen der arbuskulaeren Mykorrhiza im oekologischen Landbau zur Optimierung des Pflanzenwachstums und der Sicherung der Ertraege. Dabei wird im Rahmen von Feldversuchen der Einfluss von acker- und pflanzenbaulichen Massnahmen (Fruchtfolge, Duengung, Bodenbearbeitung) sowie der Dauer der oekologischen Bewirtschaftung auf die arbuskulaere Mykorrhiza untersucht.

Kohlenstoffspeicherung in einem ungenutzten Kalkbuchenwald des Nationalparks Hainich

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.

Schwerpunktprogramm (SPP) 1167: Quantitative Niederschlagsvorhersage, Coordination of the SPP 1167: Study of the process chain and predictability of precipitation by combining the D-PHASE ensemble and the COPS data sets in the COPS domain

In contrast to their advances in other areas, weather forecast models have not been successful in improving the Quantitative Precipitation Forecast during the last 16 years. One reason for this stagnation is the lack of comprehensive, high-quality data sets usable for model validation as well as for data assimilation, thus leading to improved initial fields in numerical models. Theoretical analyses have identified the requirements measured data have to meet in order to close the gaps in process understanding. In field campaigns, it has been shown that the newest generation of remote sensing systems has the potential to yield data sets of the required quality. It is therefore time to combine the most powerful remote sensing instruments with proven ground-based and airborne measurement techniques in an Intensive Observations Period (IOP). Its goal is to serve as a backbone for the SPP 1167 by producing the demanded data sets of unachieved accuracy and resolution. This requires a sophisticated scientific preparation and a careful coordination between the efforts of the institutions involved. For the first time, the pre-convective environment, the formation of clouds and the onset and development of precipitation as well as its intensity will be observed in four dimensions simultaneously in a region of sufficient size. This shall be achieved by combining the IOP with international programs and by collaboration between leading scientists in Europe, US and other countries. Thus, the IOP is a unique opportunity to make Germany the setting of an international field campaign featuring the newest generation of measurement systems such as scanning radar and lidar and leading to outstanding advances in atmospheric sciences.
