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.
Background: It has been hypothesized, that children could be more vulnerable to radio frequency electromagnetic field exposures from mobile telephones than adults, but no epidemiological studies of the relationship have been performed so far. The lack of knowledge causes conflicting recommendations from decision-makers, leading to anxiety and insecurity in the population. WHO has put a case-control study on childhood brain tumours as high priority on their 2006 research agenda on radio frequency electromagnetic fields. Objectives: The main goal of the study is to investigate whether use of mobile telephones increases the risk of developing brain tumours for children or adolescents. In addition, our study will provide a comprehensive dataset to investigate other potential risk factors for childhood brain tumour. Study design: The questions under study will be investigated by means of a case-control study in Denmark, Norway, Sweden and Switzerland. Cases will be identified through a combination of registry data and information from the wards treating the patients (e.g. Swiss Paediatric Oncology Group: SPOG). All incident cases of brain tumour in the age group 7-19 years between May 2004 and April 2008 will be invited to participate. In total, the study is expected to include 550 cases of brain tumours in the participating countries, thereof 100 originating from Switzerland. For each case, two control persons will be randomly selected from the general population, matched on age, sex and geographic regions. Exposure assessment: Information on the extent of exposure to radio frequency fields from mobile phones and on other known and suspected risk factors for childhood brain tumours will be obtained by means of computer assisted personal interviews conducted by an interviewer trained for this purpose. The interviews will take place either at the hospital or at the study participant's home. Objective information on the frequency and duration of mobile phone use will be obtained from mobile phone operators and from the information stored in the telephone that is in current use. Data analyses: The data will be analyzed using established statistical methods for case-control studies, primarily via logistic regression models adjusted for potential confounding factors. In order to investigate potential gene-environment interactions, DNA from saliva samples will be extracted and analysed. Polymorphisms in genes that affect oxidative metabolism, detoxification of carcinogens, DNA stability and repair, or immune response, are candidates that might confer genetic susceptibility to brain tumors.
Aiming at solution and prevention of actual and future environmental problems, EU policy resulted in many Directives concerning water and soil. Moreover, the Commission of the European Communities composed a paper 'Toward a Thematic Strategy for Soil Protection' and set up a tight time schedule. Despite of above mentioned legislative efforts an effective EU-wide approach to the problem of site remediation and groundwater contamination is hindered by a number of problems described by the CLARINET Working Group on Co-ordination of RTD on an European level: There is little synergy at EU level between national and EU RTD programmes, leading to a serious overlap of research projects and parallel expenditures and less efficient use of limited resources. The broad dissemination of project results through national RTD programmes at an European level is very modest and fragmented. percent These are the starting points of SNOWMAN-Era-Net: What do we HAVE? The consortium will produce a sound overview on programmes and their contents and management in the field specified. A database containing all relevant information will be produced and analysed. What do we WANT? A Vision Paper will define the goal of European research activities in this specific field of environmental research. How can we GET co-operation NOW? ? Specification of next steps, short- and medium-term, preparing ground in order to reach the overall goal of ERANET, i.e. to implement and conduct a research programme on bi-/multilateral level throughout Europe. Suitable tools (like uniform evaluation criteria etc.) will be developed in Working group meetings and collected within a summary report. Knowledge dissemination will be supported by a close linkage with the EUGRIS project. On this portal, all findings produced within SNOWMAN will be published and made available to a wider community. On interpersonal level, networking with the European Soil Policy Working Group or Cost activities will be maintained.
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.
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.
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.

Despite the advantages of solar membrane distillation (MD) systems very few experimental systems have been developed as opposed to the mature technologies solar PV-driven RO and solar distillation. Therefore, main objective of MEDESOL Project is the development of an environmentally friendly improved-cost desalination technology to fresh water supply in arid and semi-arid regions in EU and Third Countries based on solar MD. The layout involves the innovative concept of multistage MD in order to minimize specific energy and membrane area required and also to substantially reduce the brine generation. The aim of this work was to evaluate the technical feasibility of producing potable water from seawater by integrating several membrane distillation modules (Multi-step Membrane Distillation System). The aim is to develop systems for a capacity ranging from 0.5 to 50 m3/day. Technical simplicity, long maintenance-free operation periods and high-quality potable water output are the very important aims which will enable successful application of the systems that are based in membrane distillation. The heat source will proceed from an advanced compound parabolic solar concentrator, developed to the specific concentration ratio to achieve the specific needed range of temperatures (90ºC) and the seawater heater will include the development of an advanced non-fouling surface coatings to avoid the deposit formation (i.e. scaling) at such temperature. Laboratory tests under defined testing conditions of all components are very important for the preparation of successful field tests under real conditions.
