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.
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.

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.

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.
This GSE-FM service option provides a powerful tool for effective forest monitoring and inventory at regional scale using both EO-data and ground based observations. It is especially designed for allocating reliable and up-to-date information over large forest areas. Many regions of the world like wide parts of Russia and the Irkutsk Oblast are covered by vast forests. The countries and administrative regions often have to deal with pressing environmental problems such as frequent forest fires events, illegal logging practices as well as other human activities and natural forest disturbances. Due to the large forest areas, which are often difficult to access or characterized by insufficient infrastructure and severe climate conditions, frequent monitoring of the forest resources is a great challenge. Forest monitoring by the means of ground inventories is rather complicated or even impossible. The use of aerial photographs is also often insufficient and cost-intensive. As a result, forest information available today, often does not correspond to the current situation. This is true for wide parts of Siberia, for example. However, according to their own legislation and to fulfill international obligations up-to-date and reliable information on forest resources are essential. For instance, in order to update the Russian State Forest Account as well as for forest management and monitoring issues an annual update of forest information is obligatory. The use of EO-technologies offers an excellent tool to obtain spatial forest information. Especially for regions covered by vast forest areas the combined use of high and low resolution EO-data is the most promising and cost-efficient strategy. Therefore, this GSE-FM service option follows a two-level strategy: Level 1: Low and medium resolution satellite data are used for operational monitoring of forest changes over large areas caused by fires, cutting, and other natural and human induced disturbances. Territories where significant changes occurred are identified at this level. Level 2: Both high-resolution satellite data and aerial photos are used for a detailed inventory of all candidates registered by the first level observations. Ground truth data (inventory maps, topography, archive EO data etc.) are used in addition.
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.
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.
Communications, data and information exchange are the key elements of the operational ocean monitoring and forecasting networks, defined in the Global Ocean Observing System (GOOS). Development of observing and closely related operational forecasting system in the Black Sea region requires the exchange of significant data and information volumes. ASCABOS is designed to strengthen the communication system ensuring flexible and operative infrastructure for data and information exchange between partners and end users. ASCABOS aims to increase public awareness and to stimulate and motivate the utilization of operational oceanographic information in management and decision-making practices. In the same time, high level of the operational services must be built and retained. ASCABOS will support achievement of these crucial objectives by initiating an educational and training programme designed for young scientists and wide spectrum of end users. Considerable work has been performed on compiling meta-databases on the Black Sea environmental data, information and research within previous international initiatives and projects. To support and to strengthen the exchange between scientists, governmental managers and other users ASCABOS is planning to combine experiences and instruments in order to develop a Black Sea information system, containing all available metadata, validated and efficiently updated through the Internet. ASCABOS plans to organize and realize a cost-effective VOS pilot programme, applying modern technologies and developments for data collection, transmission, storage, use and dissemination. The VOS programme will provide data for model assimilation and respond to the GOOS demand for long-term monitoring of the marine ecosystems.

Many of the world's mountain ecosystems are moving along trajectories that couple high rates of environmental change with strong economic changes, whose collective effect may alter the ability of mountain regions to provide critical goods and services, both to mountain inhabitants and lowland communities. In order to address the environmental challenges facing the world's mountain regions in the 21st Century, we will develop an integrative research strategy for detecting signals of global environmental change in mountain environments, for defining the consequences of these changes for mountain regions as well as lowland areas dependent on mountain resources, and for facilitating the development of sustainable resource management regimes for mountain regions. Following a kick-off meeting, the details of the research strategy will be formulated through a series of product-oriented workshops dedicated to: 1) Long-term Monitoring, 2) Integrated Modelling, 3) Process Studies, and 4) Sustainable Development. The concepts developed in these Thematic Workshops will be revisited, refined and synthesised during a final Open Science Conference on Global Change in Mountain Regions. By gearing the research strategy toward implementation in mountain Biosphere Reserves, the project will take advantage of the existing UNESCO infrastructure and ongoing Global Change research in these areas. The structure of UNESCO mountain Biosphere Reserves provides ideal natural Global Change laboratories with core protected mountainous areas surrounded by lower-elevation buffer zones that are more strongly influenced by human activities. European scientific participation, capacity building and leadership will be promoted by adapting the research strategy for implementation in UNESCO's mountain Biosphere Reserves in both developed and developing countries. This will be achieved through the active participation of Biosphere Reserve managers in the development of the research strategy.
