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.

5. RP Harmonirib-Harmonisation of representative river basin data modelling - HARMONIRIB

*The Water Framework Directive (WFD) provides a European policy basis at the river basin scale. The river basin management and planning process prescribed in the WFD focuses on integrated management, involving all physical domains in water management, sectors of water use, socio-economics and stakeholder participation. As such, the WFD poses new challenges to water resources managers. In practise, the preparation of WFD river basin management plans is influenced by uncertainties in the underlying data and modelling results. The preparation of integrated water management plans for the WFD will require making a large number of decisions by operational agencies in Europe. A decision maker has to make decisions based on available information. In most cases this information is deficient, incomplete and uncertain. How should this affect the decision making. Therefore, there is a clear and urgent need for developing new methodologies and tools that can be used to assist in implementing the WFD. In order to support such research and development, it is necessary to have a network of representative river basins with datasets suitable for this purpose. This implies that the datasets, in addition to covering the diversity in terms of ecological regimes and socio-economic conditions found across Europe, must have built-in information on the uncertainties in the data. HarmoniRiB is a research and technological development (RTD) project funded by the European Commission (contract number EVK1-CT-2002-00109) that was initiated in October 2002 and will be completed in March 2006. The overall goal of HarmoniRiB is to develop methodologies for quantifying uncertainty and its propagation from the raw data to concise management information. Thus, the HarmoniRiB project aims to support the WFD implementation, by addressing issues of uncertainty in data and modelling, and by developing a 'virtual laboratory for modelling studies'. This virtual laboratory will comprise of a set of river basins, of which data relevant to modelling and the WFD implementation are readily available for the scientific community. The data can be used for comparison and demonstration of methodologies and models relevant to the WFD. HarmoniRiB is implemented by a Consortium of ten partners from eight European countries. It consists of three universities (UVA, TUC, UCLM), five public research institutes (GEUS, RIZA, CNR-IRSA, UFZ, CEH) one private sector research and consulting company (DHI) and one river basin authority (PM). The British partner of the Consortium is the Centre for Ecology and Hydrology (CEH). CEH role in the project is to develop a database design for data required to support river basin management,to populate the database with a dataset from the Kennet river basin, and to conduct a demonstratition case study on that basin.

Towards the Derivation of Quality Standards for Priority Substances in the Context of the Water Framework Directive - Identification of Quality Standards for Priority Substances in the Field of Water Policy

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.

Entwicklung von Kompostierungssystemen zur Behandlung von schadstoffhaltigen Abfällen und zur Altlastensanierung

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.

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.

FP6-SUSTDEV, Integrated Health, Social and Economic Impacts of Extreme Events: Evidence, Methods and Tools (MICRODIS)

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.

Global Earth Observation and Monitoring (GEOMON)

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.

FP6-SUSTDEV, Earthquakes, tsunamis and landslides in the Corinth rift, Greece A multidisciplinary approach for measuring, modelling, and predicting their triggering mode and their effects (3HAZ-CORINTH)

The project will contribute to better measure, model, and predict the processes leading to earthquakes, andslides, submarine slides, and tsunamis, and their effect in terms of hazard. The target area is the rift of Corinth,well known for its exceptional activity with respect to these hazards. This work will focus on the western end of the rift, close to the cities of Patras and Aigion, where the risk is highest. We will study the short term seismic hazard with methods involving seismology, geodesy, geophysics, and geochemistry. In addition to strong motion analysis and prediction, transient processes (seismic swarms, 'silent' earthquakes, fluid transients) will be studied, for a better modelling fault mechanics and earthquake preparation processes. In addition to the existing monitoring arrays and data base, specific new instrumentation will be built. Near-real time alarms systems for significant earthquakes will be developed and tested. For the long term seismic hazard, the seismic potential of active faults will be assessed on land and offshore. For submarine slope failures, places of past and future potential slumps will be mapped, and complemented by marine sediment coring and dating on selected places. Scenarios of slope failure and of coseismic displacement of the sea floor will be the inputs for tsunami modelling. The latter will be implemented using the existing high resolution bathymetry for modelling of the wave run up. Early warning alarms will be developed and tested. For landslides, the main objective is to monitor and model the perturbation of the sliding of a well documented active landslide, in response to ground shaking from local earthquakes. Continuous GPS, seismic and tilt monitoring, and repeated advanced geodesy, will quantify sliding rates and constrain first order models. The feasibility of alarm systems will be studied.

FP6-SUSTDEV, Integrating new technologies for the study of benthic ecosystem response to human activity: towards a Coastal Ocean Benthic Observatory (COBO)

Coastal ecosystems are particularly vulnerable to anthropogenic perturbation, affecting biodiversity and ecosystem stability and resilience. Shallow water sediments and their associated biota represent a reservoir for biodiversity, hosting resting and reproductive stages of planktonic organisms, and regulating carbon and nutrient biogeochemical cycles. However, the relationship between tightly coupled biological and geochemical processes in this environment is poorly defined with respect to their temporal and spatial variability. The overall objective of COBO is to integrate emerging and innovative technologies from different disciplines (physics, chemistry, biology, imagery) to provide in situ monitoring of sediment habitats, a key component of coastal marine ecosystems, in order to understand complex interactions between the biota (function and diversity) and their chemical environment. Existing technologies have limited spatial and temporal sampling resolutions and this has hampered progress in determining key parameters and in explaining biogeochemical patterns / processes and in modeling ecosystem dynamics. Improved in situ technologies are required to provide rigorous scientific information on processes regulating this unique and fragile habitat and for assessing, controlling and minimising human impact on European coastal waters thus addressing societal need. Organism-sediment processes, with both enhancing and mediating effects, are still poorly understood in shallow water sediments that receive the bulk of anthropogenic disturbance. The combination of innovative instruments from the different disciplines will provide powerful tools to significantly advance our understanding of organism sediment relations under dynamic coastal conditions and enhance predictive capability. COBO represents a major step towards the development of permanently operating benthic observatories for coastal management.

FP6-SUSTDEV, International Action for Sustainability of the Mediterranean and Black Sea EnvirOnmeNt (IASON)

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.
