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.
This project aims at reconstructing climate variability in Cuba and the Gulf of Mexico, with special interest on extreme events, such as tropical cyclones, using corals from within the Loop Current (LC), historical records, and numerical models. The LC feeds the Gulf Stream, which is crucial for the tropical heat transport to higher latitudes. Numerical models have confirmed that subtropical climate variability, and consequential changes in seawater properties, can affect both the Gulf Stream and the North Atlantic climate. However, there is a lack of long-term records of seawater properties at key sites within the Atlantic, which can be used to validate the models. The skeletal chemical composition of Cuban corals can provide such records, though they have never been used to reconstruct oceanographic and meteorological parameters. Accordingly, corals will be used to investigate: (1) the impact of Cuban climate variability on the LC seawater properties and on the European climate, and (2) the effects of global climate variability and oscillations (e. g. ENSO, NAO) on the Cuban climate in order to improve our forecasting and diagnostic capabilities of extreme events. The latter has important economic repercussions in an oil producing area, such as the Gulf of Mexico, where the occurrences of cyclones there influence the international prices of crude oil. Comprehensive calibration experiments using multiple records to determine the climate-signal precision have been elaborated within this proposal to optimize the use of corals as records of climate variability.
Der aktuelle Sachstand bei der Erstellung von Luftreinhalte- und Aktionsplänen in Deutschland wird mit Hilfe einer eingehenden Analyse derzeit veröffentlichter Pläne beschrieben (Stand: 31.08.2008). Diese Pläne stellen in der Zusammenschau eine umfangreiche Darstellung der aktuellen Luftschadstoffsituation, der verschiedenen Methoden der Prognose und der diskutierten Maßnahmen dar. Als wichtiges Hilfsmittel der vergleichenden Auswertung dient die Darstellung der Daten der Luftreinhaltepläne als thematische Karte. Es gibt zahlreiche strukturelle und inhaltliche Unterschiede zwischen den verschiedenen Entwicklungsstufen der Pläne und ebenso zwischen den Plänen verschiedener Bundesländer. Zur Klassifizierung der in den Plänen genannten Maßnahmen wurde in den vorigen Arbeiten (FKZ 204 42 222) und (FKZ 363 01 140) ein Maßnahmenschema entwickelt, das im vorliegenden Bericht nochmals erweitert wurde. Mit diesem Analysewerkzeug wurden alle bis zum 31.08.2008 vorgelegten Veröffentlichungen, d. h. Pläne, Fortschreibungen und Entwürfe, systematisch erfasst und untersucht. Um die Vergleichbarkeit der in den Plänen aufgeführten Maßnahmen zu gewährleisten, wurde die in den Vorgängerarbeiten entwickelte Zusammenstellung von standardisierten Maßnahmen weitergeführt. Diese sogenannten Standard- Maßnahmen stellen ein zentrales Element der Maßnahmenanalyse dar und bilden alle Maßnahmen ab, die in Deutschland laut den vorgelegten Plänen durchgeführt, geplant oder diskutiert werden. Die erneute Aktualisierung dient insbesondere auch dazu festzustellen, mit welchen Maßnahmen die Länder planen, die ab 2010 gültigen Luftqualitätsgrenzwerte einzuhalten. Umweltzonen haben sich, wie bereits in den Vorgängerarbeiten gezeigt, als wichtiges Element im Maßnahmenbündel etabliert. Die neue Bestandsaufnahme erfasst auch den aktuellen und geplanten Stand der Umweltzonen. Das Vorhaben diskutiert darüber hinaus die Abschätzung der Wirksamkeit der Maßnahmen im Hinblick auf das Minderungspotenzial für PM10-Feinstaub und Stickstoffdioxid unter Berücksichtigung anderer nationaler Wirkungsuntersuchungen.
This Network of Excellence (Noel) will create a European long-term inter-disciplinary research facility for research on the complex relationship between ecosystems, biodiversity and society. It will provide research support for policy assessment and development on the conservation and sustainable use of biodiversity in the European Union, and a stable facility for information retrieval and reporting on biodiversity-related issues. It will achieve this by implementing research, management and cultural changes within and between its component organisations, and through the development of integrated research agendas that will focus the research activities of its members on priority policy issues. The result will be a unique inter-disciplinary network linking a variety of stakeholders including research scientists, science communicators, policy makers and the public. In order to ensure durable integration of 24 partners from 17 countries, this Noël will build on 4 existing co-operative programmes that deal with complementary aspects of biodiversity research. These are PEER/CONNECTJLTER, ECSITE and ECNC.A novel approach to integration of ecological and socio-environmental methodologies will be developed, recognising the fact that biodiversity research should be done only in the context of ecosystems and their long-term dynamics. To achieve this, the core research undertaken by the Noël will be structured around a common framework based on the Drivers-Pressures-State-Impact-Response (DPSIR) model. This framework will ensure that research contributes directly to our understanding of the inter-relationship between biodiversity and the services it provides to society, and vice versa. The framework, and the research it supports, will also facilitate the long-term institutional changes that will be necessary to accomplish the ALTER-net objectives for durable integration.

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.
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.
