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.
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. Prime Contractor: Energieonderzoek Centrum Nederland; Petten, Netherlands.
The main objective of the project is to investigate, assess and enhance the potentiality of promising technological options (i.e., technologies, processes and concepts) for the treatment of industrial wastewater with the specific aim to provide tailor-mad e solutions to end-users for a wide range of wastewaters. Such solutions will be essentially based on the optimised integration of the investigated options and on technological improvements with respect to treatment system components, operation and control. Referring to the investigated options and the envisaged technological solutions, the project's goals are: -Investigating and enhancing the performances of promising wastewater treatment options such as aerobic granulation, integrated advanced oxidation processes (AOP) and membrane-based hybrid processes -Achieving fundamental and technological knowledge advancements necessary for advanced wastewater treatment application in different industrial sectors -Assessing the economic and environmental sustainability of promising wastewater treatment options -Developing integrated tailor-made solutions for end-users in different industrial sectors -Transferring the developed know-how to potential end-users inside and outside the project -Favouring their actual implementation for enhancing the EU Water Industry competitiveness. In order to achieve such goals, coordinated research activities will be carried out on selected options treating different wastewater. The experiences from such activities will be merged to define tailor-made solutions for end-users in different industrial sectors. A major goal will be the definition of treatment needs and framework conditions for a wide range of wastewaters based on the specific features of the options investigate d (i.e., aerobic granulation, AOP combined processes, membrane contactors, membrane chemical reactors).

Over land, observations of rain rates are more or less operational. To obtain information about precipitation at the coastal zones, weather radars are used. However, over the oceans, especially away from the main shipping routes, no direct precipitation measurements are performed. In these regions, satellite data can provide information about precipitation events. Satellites deploying passive and active microwave sensors can operate independently of cloud cover and time of day. Passive microwave sensors give crude estimates of rain rates over large areas but cannot resolve small-scale rain events of short duration as are often observed in the tropics, for example. Active microwave sensors with high resolutions, such as synthetic aperture radars can provide more reliable information. Though the effect of rain on the atmosphere is a very topical area of research, the radar backscattering mechanisms at the water surface during rain events combined with wind are still not well understood. The purpose of this project is to investigate the radar backscattering from the water surface in the presence of rain and wind in order to interpret satellite radar data produced by active microwave sensors. Furthermore, the results should be embedded into models of the radar backscattering from the water surface to allow for estimating rain rates by using satellite data. Research topics: Rain impinging on a water surfaces generates splash products including crowns, cavities, stalks and secondary drops, which do not propagate, and ring waves and subsurface turbulence. We are investigating this phenomena at the wind-wave tank of the University of Hamburg. The tank is fitted with an artificial rain simulator of 2.3 m2 area mounted 4.5 m over the water surface. Rain drops of 2.1 and 2.9 mm in diameter with rain rates up to 100 mm/h have been produced. Wind with speeds 10 m/s and monomolecular slicks act on the water surface. The influence of the rain on the water surface is measured with a resistance type wire gauge, a two dimensional laser slope gauge and an coherent 9.8 GHz (x band) continuous wave scatterometer operating at VV-, HH- and HV-polarization. The influence of rain below the water surface is measured with colored raindrops which are observed with a video camera to investigate the turbulent motion and the depth of the mixed layer. At the North Sea Port of Buesum in Germany, a scatterometer operating at all polarizations and five frequencies will be mounted during summer of this year. The radar backscatter of the sea surface during rain events will be measured in combination with meteorological observations. With help of these measurements, existing radar backscatter models of the water surface will be improved for the presence of rain events. To validate the improved models, ERS-2 SAR-images will be compared with weather radar data.
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.
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.
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.
(...) Auf der Basis der Erkenntnis, dass ein hohes Umweltbewusstsein bei großen Verhaltenskosten in der Regel nicht ausreicht, um tatsächlich umweltschonendes Verhalten zu garantieren, stellt die Verringerung der individuellen Kosten für umweltschonendes Verhalten mittlerweile ein wesentliches Ziel von Interventionsmaßnahmen im Umweltbereich dar. Von besonderer Bedeutung ist in diesem Kontext der Kostenfaktor monetärer Preis, da in ihm eine der zentralen Steuerungsvariablen zur Förderung umweltschonenden Verhaltens gesehen wird. Umweltschonendes Verhalten darf also nicht durch höhere Kosten bestraft werden, sondern ist durch gezielte Anreizstrukturen zu fördern. Zusätzlich ist jedoch die Bedeutung von inneren umweltbezogenen Werthaltungen und Einstellungen zu berücksichtigen. Gegenstand des Projekts ist daher die Analyse des Zusammenwirkens von ökologischer Normorientierung und monetären Kosten im Bereich des individuellen Mobilitätsverhaltens. Auf theoretischer und empirischer Ebene existieren hierzu eine Reihe - zum Teil widersprüchlicher - Hypothesen, über die im Rahmen einer quasiexperimentellen Feldstudie eine Entscheidung herbeigeführt werden soll. Als Untersuchungskontext wird das Mobilitätsverhalten von Personen gewählt, da hier ein unmittelbarer Zusammenhang zu globalen Umweltveränderungen (CO2-Anreicherung der Erdatmosphäre) gegeben ist. (...) Im Fokus des aktuellen Projekts steht erneut die Analyse des Wahlverhaltens zwischen Pkw und öffentlichem Personennahverkehr (ÖPNV), wobei die monetären Kosten für die Nutzung von Pkw und ÖPNV in drei Stufen quasi-experimentell variiert werden: (a) ÖPNV-Nutzung teurer als Pkw-Nutzung, (b) ÖPNV-Nutzung und Pkw-Nutzung preisäquivalent, (c) ÖPNV-Nutzung billiger als Pkw-Nutzung. Diese drei-stufige Variation erfolgt hierbei für drei verschiedene Standardstrecken der Upn, und zwar für die drei Zwecke Arbeit/Ausbildung, Einkaufen und Freizeit. Zusätzlich wurde ein Fragebogen entwickelt, in dem neben den bereits im Vorläuferprojekt entwickelten Items zum modifizierten Norm-Aktivations-Modell (neun Subskalen), subjektive Repräsentationen von Preisen (Kostenschätzungen Pkw/ÖV der definierten Standardwege, der subjektiv wahrgenommener eigener finanzieller Spielraum, wahrgenommene Angemessenheit/ Fairness von Preisen und geldspezifische Einstellungen) und Repräsentationen nichtmonetärer Verkehrsmittelattribute (z.B. Komfort, Sicherheit etc.) berücksichtigt werden. (...) In der Auswertung soll überprüft werden, wie monetäre Kosten für räumliche Mobilität subjektiv repräsentiert werden und in welchem Verhältnis subjektive und objektive Kosten stehen. Hier wird erwartet, dass die monetären Kosten für die Pkw-Nutzung im Vergleich zu den Kosten der ÖPNV-Nutzung eher unterschätzt werden. (...) Ein Ziel der Forschungsbemühungen liegt in der Ableitung von Prognosen über die Akzeptanz monetär ausgerichteter Interventionsmaßnahmen zur Förderung umweltschonender Verhaltensweisen.
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.
