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.

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.

With a focus on transport, the project intends to increase the understanding among relevant actors of the benefits of environmental technologies for a wider application of these technologies. It will build on the ETAP actions on targeted training and awareness raising. Pursuing this aim, the following support activities will be undertaken: 1) conceptualising and organising of 3 workshops with relevant stakeholders for stock taking, identifying obstacles and possible solutions as well as best practice examples; 2) organising a concluding conference on the basis of experiences made in the course of the project (to produce recommendations); intended for senior executives within the sector in order to ensure that the learning from the project is communicated at a level that can help to ensure as broad a take-up and dissemination as possible. 3) Producing Background Notes and Policy Briefs on training needs and awareness raising. The Background Notes will serve as a basis for the Conference discussions; the Policy Briefs will disseminate the projects findings and recommendations beyond the project to a wider public. 4) Specifying a low-cost, easily disseminated e-learning solution that addresses the overall objective of the project: increasing awareness amongst those working in this sector of underlying issues and dilemmas as well as of solutions and good practice. This activity also includes recommendations for routines to maintain the awareness and competence in order to ascertain continuous, long-term effects of the efforts.

Environmental risk assessment of pharmaceuticals (ERAPHARM)

The overall objective of ERAP harm is to improve and complement existing knowledge and procedures for the environmental risk assessment (ERA) of human and veterinary pharmaceuticals. Based on EU regulatory frameworks on the ERA of pharmaceuticals and on the outcome of previous projects ERAP harm will address the following aspects: It will investigate previously unstudied major routes leading to exposure of the terrestrial and aquatic environment and subsequent fate of pharmaceuticals in surface water and sediment. Factors and processes affecting the behavior of pharmaceuticals in the environment will be studied on the laboratory, semi-field and fieldscale. A scenario-based exposure assessment system will be developed for predicting concentrations of pharmaceuticals in soils, surface waters and sediments and leaching to groundwater. It will be investigated if environmentally relevant concentrations of pharmaceuticals pose a risk to aquatic and terrestrial organisms. Pharmaceuticals and selected transformation products will be screened using in vitro and low complexity bioanalytical tests in order to provide a first hazard characterization and to target higher tier testing. Higher tier test methods will be improved and applied for detecting the effects of long-term, low-level exposure to pharmaceuticals on aquatic and terrestrial invertebrates and fish. It will be evaluated if information on pharmaco- and toxicodynamics in mammalian species can be used to predict effects of pharmaceuticals on environmental organisms. Moreover, the effects of antibiotics on microbial communities will be studied with a main focus on the spread of genetically encoded resistance. Based on the developed approaches recommendations will be provided on how to improve the ERA procedures for pharmaceuticals. A guidance document will be compiled that will be made available to regulators, industry and the scientific community.

FP6-SUSTDEV, Groundwater Artificial recharge Based on Alternative sources of wateR: aDvanced INtegrated technologies and managEment 8GABARDINE)

Aquifers are the main source of water in most semi-arid areas of the Mediterranean basin. As a result of over-exploitation hydrologic deficits of varying acuity prevail in these areas. Seawater intrusion and pollution have been identified as the primary factors for quality degradation. Further deterioration can be expected based on trends in the precipitation regime attributed to climate change. The objective of this project is to identify alternative sources of water and to investigate the feasibility, both environmental and economic of their utilization. Alternative water sources to be artificially recharged comprise: surface water runoff, treated effluent, and imported water. Furthermore, brackish water bodies, present in many aquifers could be utilised after desalination. The project structured into eight work-packages comprehensively addresses all issues related to the problem: expected precipitation rates, recharge and water budgets, identification of potential alternative water sources and technologies for their utilization, development of tools for the management of groundwater resources under artificial recharge conditions, aquifer vulnerability assessment, characterization of the unsaturated zone, and mixing effects. Four test sites have been selected for practical application of the approach. Substantial field testing, integration of technologies and findings to ensure optimal implementations of aquifer recharge alternatives, quantification of socio-economic impacts and development of dissemination platform are planned. Finally a carefully designed project management shall drive and accompany the project execution in order to ascertain consistency and efficiency.

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.

Emissionsmessungen an einer Tankstelle mit dem VACONOVENT-System

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.

FP6-SUSTDEV, International Conference on 'Integrative Approaches Towards Sustainability' (Baltic Sea Region sharing knowledge internally, across Europe, and world-wide) - SHARING

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.

Policy Analysis for Sustainable Agricultural Development - PASAD

Objectives: The PASAD project aims at contributing to a deeper understanding of sustainable rural development. Its major objective is to draw a more comprehensive picture of the rural economy through integrating various determinants of rural development and several methodologies, which allows the evaluation of linkages and interaction effects. Decreasing soil fertility implies decreasing yields over time and hence lowers the real incomes of already poor farmers even further. Sustainability in agricultural production depends on various interdependent aspects that require integrated analytical approaches to address the complexity involved. Smallholder production of food crops in poor countries is particularly vulnerable to hazards that are related to (i) production technologies as well as (ii) factor and commodity markets. The former aspect includes appropriate input use and land management, while the latter particularly considers rural labor markets, intermediate input markets, and commercial output markets. In this context, the project focuses on three crucial aspects, namely (i) institutional and other determinants to foster the degree of commercialization of agricultural small-scale produce, (ii) alternative occupational choices in rural labor markets with respect to agricultural and non-agricultural employment, and (iii) biophysical aspects concerning soil-conserving production technologies. The main hypothesis is that all three aspects need to be addressed sufficiently and simultaneously in order to promote sustainable smallholder agricultural production that is able to contribute to overall economic growth and development and, consequently, to food security. Methodology: The project follows an interdisciplinary approach, which combines several methodologies within economic and social sciences: Computable general equilibrium (CGE) modelling, Bio-economic household modelling, Household and labor force survey analysis, Institutional analysis, GIS-based spatial econometrics.

Biological Detoxification of Fumonisins

The overall aim of this project is to find microorganisms or specific enzymes which are able to degrade and detoxify fumonisins, a recently found class of mycotoxins. Such microorganisms or enzymes should then be used as part of a feed additive which manages the degradation of these toxins in the intestinal tract of animals during feed digestion. The major project phase is the screening for such fumonisin degrading microorganisms or enzymes. In first place these organisms should be newly isolated strains out of various habitats, but also strain collections are investigated as well as commercially available enzymes. Characterisation of newly found microorganisms via morphological, physiological and molecular biological methods represents another phase within this project. The third major project phase includes the development of appropriate analytical methods for analysis of samples from degradation experiments out of various different matrices. HPLC, ELISA and LC-MS methods are investigated. The characterisation of metabolites evolving during the microbial and/or enzymatic degradation of fumonisins is defined as a working package as well. In order to show the real detoxification of fumonisin B1 by the microorganisms (or enzymes) several different toxicity test-systems (cell-culture assays, bioassays)are under investigation.
