BACKGROUND: The Kingdom of Jordan belongs to the ten water scarcest countries in the world, and climate change is likely to increase the frequency of future droughts. Jordan is considered among the 10 most water impoverished countries in the world, with per capita water availability estimated at 170 m per annum, compared to an average of 1,000 m per annum in other countries. Jordan Government has taken the strategic decision to develop a conveyor system including a 325 km pipe to pump 100 million cubic meters per year of potable water from Disi-Mudawwara close to the Saudi Border in the south, to the Greater Amman area in the north. The construction of the water pipeline has started end of 2009 and shall be finished in 2013. Later on, the pipeline could serve as a major part of a national water carrier in order to convey desalinated water from the Red Sea to the economically most important central region of the country. The conveyor project will not only significantly increase water supplies to the capital, but also provide for the re-allocation of current supplies to other governorates, and for the conservation of aquifers. In the context of the Disi project that is co-funded by EIB two Environmental and Social Management Plans have been prepared: one for the private project partners and one for the Jordan Government. The latter includes the Governments obligation to re-balance water allocations to irrigation and to gradually restore the protected wetlands of Azraq (Ramsar site) east of Amman that has been depleted due to over-abstraction by re-directing discharge of highland aquifers after the Disi pipeline becomes operational. The Water Strategy recognizes that groundwater extraction for irrigation is beyond acceptable limits. Since the source is finite and priority should be given to human consumption it proposes to tackle the demand for irrigation through tariff adjustments, improved irrigation technology and disincentive to water intensive crops. The Disi aquifer is currently used for irrigation by farms producing all kinds of fruits and vegetables on a large scale and exporting most of their products to the Saudi and European markets and it is almost a third of Jordan's total consumption. The licenses for that commercial irrigation were finished by 2011/12. Whilst the licenses will be not renewed the difficulty will be the enforcement and satellite based information become an important supporting tool for monitoring. OUTLOOK: The ESA funded project Water management had the objective to support the South-North conveyor project and the activities of EIB together with the MWI in Jordan to ensure the supply of water for the increasing demand. EO Information provides a baseline for land cover and elevation and support the monitoring of further stages. usw.
Projektziel war die experimentelle Untersuchung der Vertikalstruktur der konvektiven Grenzschicht im Grossraum Wien mittels Radiosonde, Fesselballon, Sodar, Schwebeballonen und Motorseglern. Der umfangreiche Datensatz wurde zur Bestimmung von Mischungshoehen, der Untersuchung der Struktur von Thermikblasen sowie zur Validierung von Trajektorienberechnungen verwendet. Die gemessenen Mischungshoehen wurden mit Modellergebnissen (OML, Daenemark) verglichen. Unterschiede, die sich bei der Verwendung verschiedener Methoden ergeben (Radiosonden - Sodar - Modell), konnten erklaert werden, eine allgemeingueltige Messmethode bzw. ein entsprechender Modellansatz fehlt noch (auch international). Die Vertikalgeschwindigkeit wurde waehrend der Messkampagne mit dem Sodar und den Schwebeballonen erfasst. Beide Instrumentarien messen im Mittel mehr aufwaerts als abwaerts gerichtete Vertikalgeschwindigkeiten. Weiters wurde die Struktur von Thermikblasen anhand der Messdaten untersucht und eine Methode gefunden, mit der die Genauigkeit von Trajektorien erhoeht werden konnte.
SHAPE-RISK aims at optimising the efficiency of integrated risk management in the context of the sustainable development of the European process industry. The proposal addresses sustainable waste management and hazard reduction in production, storage and manufacturing. The main deliverable of the SHAPE-RISK process will be recommendations to design future cleaner and safer industrial systems. These recommendations will be discussed and endorsed by the Industry. And finally an agenda of actions, approved by Industry, will be done. The goal is to support life-cycle safety and minimisation of accident, pollution and emissions, from the producer of raw materials to the end-product delivered by the industrial installation. In operational terms, SHAPE-RISK aims at structuring a network with the organisations providing technical support to the Authorities in charge of the SEVESO II, IPPC and ATEX directives. This network organised in a Co-ordination Action will interact with the other stakeholders: Industry, the Public, representatives of Communities, International Organisation and NGOs. In 3 years, the result of SHAPE-RISK will be an integrated approach of the different components of risk management and the optimisation of the resources devoted to risk control (environment protection and accident prevention). It will be achieved by enhancing synergy between European, national and regional programmes, and also by taking into account the needs of the pre-accession countries. SHAPE-RISK will result in the dissemination of knowledge and in the specification of research activities to address innovative breakthrough that will serve the construction of safer and cleaner industrial systems. SHAPE-RISK then contributes to the integration and reinforcement of the European Research Area in risk prevention.
Objective: SHIVA aims to reduce uncertainties in present and future stratospheric halogen loading and ozone depletion resulting from climate feedbacks between emissions and transport of ozone depleting substances (ODS). Of particular relevance will be studies of short and very short-lived substances (VSLS) with climate-sensitive natural emissions. We will perform field studies of ODS production, emission and transport in understudied, but critical, regions of the tropics using ship, aircraft and ground-based instrumentation. We will parameterize potential climate sensitivities of emissions based on inter-dependencies derived from our own field studies, and surveys of ongoing work in this area. We will study the chemical transformation of ODS during transport from the surface to the tropical tropopause layer (TTL), and in the stratosphere, using a combination of aircraft and balloon observations together with process-oriented meso-scale modelling. These investigations will be corroborated by space-based remote sensing of marine phytoplankton biomass as a possible proxy for the ocean-atmosphere flux of ODS. From this a systematic emission inventory of VSLS ODS will be established to allow construction of future-climate scenarios. The impact of climate-sensitive feedbacks between transport and the delivery of ODS to the stratosphere, and their lifetime within it, will be studied using tracer observations and modelling. Further global modelling will assess the contribution of all ODS, including VSLS (which have hitherto normally been excluded from such models) to past, present and future ozone loss. Here, the sensitivity of natural ODS emissions to climate change parameters will be used in combination with standard IPCC climate model scenarios in order to drive measurement-calibrated chemical transport model (CTM) simulations for present and future stratospheric ozone; to better predict the rate, timing and climate-sensitivity of ozone-layer recovery.
Nach den Kläranlagen tragen maschinentechnische Aggregate in den Sonderbauwerken der Abwasserableitung mit 10 - 15 Prozent einen erheblichen Anteil am Gesamtenergiebedarf der Abwasserentsorgung bei. Ob und durch welche Maßnahmen Einsparungspotenziale realisierbar sind, wurde im Rahmen des Vorhabens untersucht. Hier wurden - der Energiebedarf von Sonderbauwerke ermittelt, - mittels Variantenbetrachtung ein energieeffizienter Planungsansatz für Abwasserpumpwerke entworfen, - weitergehende Maßnahmen für einen energieeffizienten Betrieb von Sonderbauwerken in der Kanalisation aufgezeigt, - die Betriebssicherheit energetisch optimierter Pumpwerke mittels Sensitivitätsbetrachtungen überprüft und - die Vorgehensweise für eine energieoptimierte Planung in einem Pflichtenheft für Betriebs- und Energieeffizienzanalysen von Sonderbauwerken in der Siedlungsentwässerung zusammengefasst. Bei der Auswertung der Betriebsdaten zu den Energieverbräuchen von rd. 200 Pumpwerken ergaben sich Datendefizite. Bei nur einem Drittel der Pumpwerke standen Daten für eine Energieanalyse zur Verfügung. Der Energiebedarf der analysierten Pumpwerke betrug 4-15 Wattstunden je Kubikmeter und Meter Förderhohe (Wh/(m3 x m)). In Ausnahmefällen lagen die Energiebedarfswerte darüber. Im Vergleich benötigen effizient arbeitende Pumpwerken zwischen 4-6 Wh/(m3 x m). Bei der Energieoptimierung von Abwassersystemen gibt es im Wesentlichen vier bewährte Strategien, um den Energiebedarf zu reduzieren: - Senkung des Bedarfes an Transportenergie. - Einsatz effizienter Systeme. - Richtige Konzeption und Dimensionierung der Förderanlagen. - Lastabhängiger Betrieb mit Spitzenlastmanagement. Wie eine energetisch optimierte Planung sowie ein energetisch optimierter Betrieb zu gestalten ist, wurde mittels Variantenbetrachtung am Beispiel des Pumpwerks Gelsenkirchen-Polsum gezeigt. Für die Darstellung der Einsparungspotentiale sind die Bau und Betriebskosten in Relation zu den Energiekosten zu stellen. Werden die Energiekosten auf die gesamten Neu- oder Umbaukosten bezogen, nehmen die Energiekosten eine untergeordnete Rolle ein. Betrachtet man ausschließlich die elektrotechnischen Einbauten eines Pumpwerkes als Investitionskosten, lassen sich über den verminderten Energiebezug hohe Einsparungspotentiale aufzeigen. Eine intensive Energieanalyse von Pumpwerken und die daraus resultierenden Maßnahmen können eine Reduzierung des Energiebedarfes von rd. 20 Prozent erzielen. Dabei ist jede Anlage mit ihren spezifischen Randbedingungen zu betrachten. Die Sanierungsansätze können durch die Simulation des Pumpwerksbetriebes in einem Berechnungsmodell bewertet werden. Hierzu sind belastbare Betriebsdaten Voraussetzung. Die Durchführung eines Energiechecks ist ein erster Schritt hin zu einem energieeffizienten Betrieb von Abwasserpumpwerken.
The goal of this study was to enable a prognosis on the future rainfall conditions of the Nile Equatorial Lakes regions by delivering time-series of monthly rainfall sums for the time-period from 2021 to 2050 that can be used for all kinds of applications. One example might be the dimensioning of hydraulic structures. In these very long lasting investments, future climatic conditions have to be considered during present planning and construction.The principal sources of information on future climate conditions are General Circulation Models (GCMs). These are physically based atmospheric models that resemble a numerical weather prediction system but on a much coarser scale. This forecast cannot be perfect. Especially, it cannot predict single values, e. g. if January 2050 will be rather wet or dry, but only climatic references, i.e. state, if Januaries in general will become wetter or dryer in the future. Even if the predictions of a GCM were perfect, its output could not be used directly for hydrological purposes, due to its coarse resolution. The monthly precipitation values that are provided by the GCM present the spatially averaged precipitation over a grid cell of several thousand square kilometres. This 'block rainfall' can differ significantly from rainfall measured at the ground. Rain gauges are influenced by local effects like micro climatic conditions or orographic effects of mountain ranges that GCMs are not able to resolve.This study combined the information from different data sources. As global trend information, monthly precipitation values from two GCMs (ECHAM5 and HadCM3) were used. Three CO2-emission scenarios (A1b, A2 and B1) were considered in this data. As local ground reference observed monthly rainfall sums from several rain gauges in East Africa as well as from three reanalysis projects (Climate Research Unit, University of Delaware and GPCC) were used.At each rain gauge or observation point in the reanalysis a technique called 'Quantile-Quantile-Transformation' was applied to establish a relationship between the Cumulative Distribution Function (CDF) of the GCMs and that of the ground references during the calibration period from 1961-1990. The CDFs were fitted by non-parametric Kernel-Smoothing. To account for potential shifts in the annual cycles of GCMs and ground references, the transformations was done separately for each month.Assuming that the relation between Global Model and local response will be constant in the future, the global predictions of the GCM can be downscaled to local scale, leading to future rainfall scenarios that are coherent with observed past rainfall.Combining the data from three CO2-emission scenarios of two GCM with three reanalysis data sets, an ensemble of 18 different rainfall time-series was created for each observation point. The range of this ensemble helps to estimate the possible uncertainties in the prognosis of future monthly precipitation sums from 2021 to 2050.
DE-LIGHT Transport is a multi-national initiative supported by the European Commission's Framework 6 programme that is investigating the design and manufacturing of lightweight sandwich structures in the marine, rail and freight container industries. Sandwich materials, consisting of two thin facings separated by a low density core, can be used to produce structures that are both light and stiff. They also offer opportunities for parts reduction through design integration, improved surface finish and lower assembly and outfitting costs. DE-LIGHT Transport aims to further promote the use of sandwich materials by developing key technologies that will support the practical realisation of robust sandwich designs. Specifically, this will include: - A multi-material sandwich design tool. Previous work has often focussed on a particular type of sandwich construction (e.g. laser-welded steel or composite). This has tended to yield niche results with limited applicability. DE-LIGHT Transport will implement a more generic design approach that will allow the evaluation and optimisation of a wide range of material and structural mixes according to the requirements of a given application. - Strategies for joining, assembly and outfitting ? the bringing together and integration of separate sandwich panels and/or sub-components to produce finished structures. In particular, modular approaches for the off-line production of sandwich assemblies to exploit economies of scale will be developed. Testing and validation procedures ? to provide accurate and reliable methods of determining fitness for purpose. The above technologies will be demonstrated within the project through the design and manufacturing of six prototype structures. These will include deck and deckhouse structures for ships, a rail vehicle cab, and a freight container. Risk-based design principals will be applied throughout to ensure that the new designs comply with existing regulatory frameworks. It is anticipated that DE-LIGHT Transport will provide designers of vehicles and vessels with practical approaches to the implementation of sandwich solutions as an alternative to traditional stiffened-plate designs. In this way, the benefits of sandwich construction will be unlocked for a wider range of applications.
Objective: Increasing awareness by the public opinion about environmental issues, energy and material conservation at all stages of product life (from raw materials to disposal/recycling) is putting the industry in general and the transport industry in particular under increased pressure to reduce CO2 emissions and save energy. Environmental protection and safety will be increasingly influenced by legislation. The European transport industry is estimated to generate 22 percent of the carbon dioxide emission. As the car population is expected to grow 40 percent by the year 2010 new tough targets for reducing emissions by 30 percent in 2010 are being set by the EU, against the state of the art technologies of 1995. It is generally agreed by the industry that reductions of this size will require a change in current technologies. Multi-material technology (sandwich and/or hybrid materials) is becoming increasingly important in new vehicle design. Public service vehicles (buses and coaches) are regarded as primary targets for application of sandwich construction and multi-materials. Public service vehicles (PSV) play a major role in the transportation industry of both industrialized and developing countries. The proposed project will be focused on the development of a novel technology to manufacture bus/coach bodies using sandwich multi-material panels. The main overall objectives of the project are: - Solving the problem of reducing weight and production costs of land transport vehicles through the development of a technology of modular bus/coach construction, using 'all composite' multi-material sandwich panels instead of steel/aluminium space frame lined with sheets of different materials. - Devise design methodologies that reduce production lead time through reduction of number of components, functional integration, and allowance for dismantling, easy repair and recycling.

Objective: Hydrogen storage is a key enabling technology for the extensive use of H2 as energy carrier. In fact, one of the greatest technological barriers to the widespread introduction of hydrogen in vehicles is an efficient and safe storage method. Providing economically and environmentally attractive solutions for these three storage options for transport applications and reinforcing the competitiveness of the European car industry are indeed the main STORHY objectives. This IP is a European initiative on automobile H2 storage driven by major European car manufacturers and covering the full spectrum of currently qualified technologies. Although the primary target of STORHY is the automobile industry, the preparation of spin-offs for stationary systems is also considered. In the three vertical SPs, viable solutions will be developed based on the defined requirements. SP Pressure Vessel concentrates on developing a 700 bar storage technology including production technologies for composite vessels. SP Cryogenic Storage will develop free form lightweight tanks manufactured from composites as well as adequate production technologies. SP Solid Storage assesses current progress in the storage of solid materials and will focus its primary research activities on alienates. Furthermore, up scaling of the material production process will be considered resulting in the construction and testing of prototype tanks. These developments are accompanied by safety studies and pre-normative research within SP SAR. The three storage technologies will be evaluated applying technical, economic, social and environmental criteria in SP Evaluation. The final outcome of the project is to identify the most promising storage solution for different vehicle applications. Such results should illuminate the future perspectives of H2 storage for transport and stationary applications and assist decision makers and stakeholders on the road to an H2 economy.
