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.

Sustainable sanitation system for low-income densely populated urban areas in Indonesia (Case study: Kali Rungkut Sub-District, Surabaya, East Java)

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.

Mesoscale Ocean Radar Signature Experiments (MORSE)

MORSE was a joint European project, carried out by six partner institutions in France, Great Britain, and Germany. It was financially supported by the Commission of the European Community as a part of the Marine Science and Technology (MAST) program under contract no. MAS3-CT95-0027. The objective of the project was to gain an understanding of the physical processes involved in radar signatures of internal waves using laboratory tank, airborne radar, and satellite imagery. To achieve the ultimate goal, independent numerical models are needed which are capable of predicting radar backscattering for all radar bands, extracting ocean surface characteristics at high spatial resolution, predicting internal wave fields in time and space, and inverting radar signatures into geophysical parameters. Existing models were not sufficiently reliable to produce quantitative results in order to retrieve the three-dimensional structure of the ocean's hydrodynamic processes. Progress in the understanding and mathematical description of different processes and increasing capacity of modern computers opens doors towards much more detailed, comprehensive models. The activities of the Satellite Oceanography group of the University of Hamburg within the framework of MORSE focused on theoretical considerations regarding the hydrodynamic modulation of ocean waves by spatially varying current fields over internal waves and the radar imaging of the resulting roughness variations. This research was based on our advanced radar imaging model which describes the modulation of the complete two-dimensional ocean wave spectrum according to wave-current interaction theory and the backscattered radar signal by a composite surface model. In addition, the Satellite Oceanography group has wide experience regarding the analysis of radar signatures of internal waves. A large number of ERS-1 / ERS-2 SAR images of internal waves in the Strait of Gibraltar and in the Strait of Messina was analyzed. Furthermore, numerical hydrodynamical models were developed, which are capable of describing the generation and propagation of internal tides and their disintegration into internal solitary waves. The MORSE project has provided an opportunity to exploit and extend the knowledge obtained in previous remote sensing projects and to calibrate and validate the corresponding numerical models.

FP6-SUSTDEV, Integrated Health, Social and Economic Impacts of Extreme Events: Evidence, Methods and Tools (MICRODIS)

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.

FP6-SUSTDEV, Sustainable Water management Improves Tomorrow's Cities'Health (SWITCH)

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.

FP6-SUSTDEV, Assessing Large-scale environmental Risks with tested Methods (ALARM) - TTC

Based on a better understanding of terrestrial and freshwater biodiversity and ecosystem functioning ALARM will develop and test methods and protocols for the assessment of large-scale environmental risks in order to minimise negative direct and indirect human impacts. Research will focus on assessment and forecast of changes in biodiversity and in structure, function, and dynamics of ecosystems. This relates to ecosystem services and includes the relationship between society, economy and biodiversity. In particular, risks arising from climate change, environmental chemicals, biological invasions and pollinator loss in the context of current and future European land use patterns will be assessed. There is an increasing number of case studies on the environmental risks subsequent to each of these impacts. This yields an improved understanding on how these act individually and affect living systems. Whereas the knowledge on how they act in concert is poor and ALARM will be the first research initiative with the critical mass needed to deal with such aspects of combined impacts and their consequences. So far the ALARM consortium combines the expertise of 54 partners from 26 countries (19 EU, Bulgaria, Romania, Israel, Switzerland, Russia, Chile, and Argentina). Within this call we propose to include 16 new TTC partners from Russia, Belarus, China, South-Africa, India, Croatia, Ukraine, Serbia & Montenegro, The Philippines, Bolivia, Guatemala, and Mexico, in order to complement expertise and geographical coverage of the existing consortium.

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.

Managing water scarcity: Intelligent tools and cooperative strategies

MAI-TAI deals with integrated water resources management. It is designed as a coordination action of leading research and innovation operators, aiming at developing a coherent set of innovative, relevant and cooperative policy options and management strategies. Regionally it works with partners from China and India, and the work will focus around two lead river basins: The Hai river basin in North-East China and the Yamuna river basin in North India, both in arid and/or semi arid regions. The proposal features the following core coordination activities: 1. Enabling a dialogue between researchers and practitioners promoting state of the art and indigenous technologies and practices: The consortium believes that modern systems alone are not capable of solving the water needs of the people in many developing countries, and there is a strong need of generating innovative options through cross fertilization between both worlds. This cross-fertilization will be enabled by methods and rich experiences of user innovations research. 2. Based on (1), innovative policy options and management strategies will be compiled. Then, a multi-stakeholder interaction in order to evaluate these options and strategies will be carried out, supported by intelligent knowledge management tools: In the presence of a variety of actors (institutions, organisations, individuals) each with specific forms of knowledge with respect to scale, topic, reasoning processes, and a large number of information expected to be generated through the multi-stakeholder interaction, the issue of learning and knowledge management is of paramount importance. A strong impact of the coordination action is ensured by a highly inter- and transdisciplinary team, encompassing internationally reputable scientific institutions as well as strong governmental partners and NGOs. The latter two will considerable facilitate a wide and in particular meaningful stakeholder dialogue throughout the project.
