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.
The building sector shows enormous energy- and material flows. 40 percent of the European primary energy consumption refers to buildings and the building sector is responsible for more than 50 percent of waste materials in Europe. The European commission is aware of the importance of the building sector for sustainability and forces among other things sustainable development on a legislative level. Examples are the European Building Directive (2002/91/EG) and the Communication from the Commission to Council and the European Parliament, COM (2005) 718 'Thematic Strategy on the Urban Environment. As already mentioned the building sector offers large potentials towards a sustainable development. But how to measure and assess sustainability of buildings? In order to assess all environmental impacts of buildings applicable instruments are required, considering the whole life cycle, including ecological issues and economical and social aspects. LCA (Lifecycle analysis) comprises a comprehensive accounting of all material and energy inputs of a building throughout its life cycle and consolidates the results in form of an environmental evaluation of the building. In the current project existing assessment instruments for the building sector are screened, compared, and tested regarding their suitability for daily use. Within the project integrative European wide standards for Life Cycle Assessment of buildings, as well as recommendations for stakeholders, landlords and designers will be worked out. Dissemination of LCA-applications for the building sector will be done by workshops and training sessions for above mentioned target groups.

Globalization raised the importance of food safety and quality concerns. Developed countries implement precautionary food regulation policies to protect their affluent consumers from unsafe food imported from developing and transition countries. However, the alarming number of trade disputes at WTO evidences cases of abuse of such policies. While claims on protectionist nature of food regulations are valid in principle, yet there is little empirical evidence about their economic effects. The questions of 1) quantification of trade impact of food standards and 2) investigation of national food regulation systems are absolutely essential for the new trade agenda. These problems for developing countries are on the focus of trade policy debate, whereas for transition countries are not considered seriously. Such a research for these recently liberalized markets gains a special significance. - The proposed research will employ Gravity Model for quantitative estimation of impact of EU aflatoxin standards on transition countries- exports.- Russian food regulations for cereal value chain, their enforcement and monitoring mechanisms will be investigated through value chain and cost-benefit analysis.- Compliance of Russian norms with EU standards will be estimated applying comparative advantage analysis.The study area is Stavropol region of the Russian Federation. Local experts will contribute to the construction of the research data set and analysis. The results of the research will assist 1) international policy makers in designing new global trade agenda and 2) Russian producers, exporters and decision makers in improving cereal value chain.
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.
BOmobil - so heißt der Elektrokleintransporter, den die Hochschule Bochum mit den Partnern Composite Impulse, Delphi, Scienlab, den Stadtwerken Bochum und dem TÜV NORD, gefördert im Rahmen des Wettbewerbs ElektroMobil.NRW serienreif entwickelt. Die Anforderungen von klein- und mittelständigen Unternehmen für den Regionalverkehr der Zukunft bestimmen das Konzept. Elektromobilitat und ansprechendes Design müssen sich nicht ausschließen, das beweist das BOmobil. Technologisch zeigt der Prototyp eine radikale Abwendung von herkömmlichen Automobilkonzepten: keine zentrale Antriebseinheit mehr - stattdessen Radnabenmotoren. So entsteht Raum für die Neugestaltung des Innenraums. Zwei Sitzplätze, Platz für eine Normgitterbox, Höchstgeschwindigkeit ca. 130 km/h, Reichweite mehr als 150 Kilometer - Elektromobilität für den Alltag. Alle Komponenten des elektrischen Antriebsstrangs werden im sogenannten Skateboard untergebracht, der tragenden Struktur, die aus Aluminium-Leichtbau-Profilen genietet und geklebt wird. Diese Variante des Aufbaus ermöglicht eine hochfeste Struktur, die für einen Kleintransporter die nötige Crash-Sicherheit bietet und flexible Aufbauvarianten zulässt. Die Batterie, die Traktionswechselrichter und die Motoren sind organisch zueinander angeordnet. So lassen sich kurze Leitungswege und ein niedriger Schwerpunkt realisieren. Durch die selbst entwickelten Radnabenmotoren wird das Antriebsmoment dort generiert, wo es benötigt wird und die eingesparte Antriebseinheit im Aufbau vergrößert das Ladevolumen des Fahrzeugs. Für die Batterie kommt die Lithium-Eisen-Phosphat-Technologie zum Einsatz. Das nötige enge Temperaturband für deren Betrieb wird im Rahmen des Thermomanagement des Fahrzeuges realisiert. Die Auswahl geeigneter thermisch isolierender Karosserie- und Scheibenwerkstoffe ist dabei von zentraler Bedeutung, um eine aktive Kühlung bzw. Heizung in deutlich geringerem Maße als in konventionellen Fahrzeugen erforderlich zu machen. Die Karosserie wird aus ABS-Kunststoff und Faserverbund-Kunststoff gefertigt. Die Kunststoffbauteile haben sowohl strukturelle, als auch warme- und geräuschdämmende Funktion. Während in konventionellen Fahrzeugen Einscheiben-Sicherheits- und Verbundglas eingesetzt wird, erfolgt im BOmobil soweit möglich die Verwendung von Kunststoffscheiben. Zur Kostenreduktion werden für das Fahrwerk Standardkomponenten des OPEL Zafira verwendet.
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.
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.

In daily life, construction polymers play an important role. Most of products are not reusable for different reasons (cost, hygiene, ) so the need of an environment saving production and disposal is evident. To besides from the obvious task on saving resources and environment, there is also a growing economical interest in this issue. On of the most promising candidates for a thermoplastic construction polymer that can be manufactured from bio-renewable resources and is biodegradable is Polylactic acid (PLA), for which Corn starch (in the U.S.) or sugarcanes (rest of world) are the common feedstock. Polylactic acid can be processed like most thermoplastics into fiber (for example using conventional melt spinning processes) and film. However, the low glass transition temperature prohibits many applications, like usage for coffee cups that will simply soften and flow away upon filling with hot drinks. One popular option to cope with this is the modification with other polymers, either conventional product or even enantiomers of PLA itself. For example, the melting temperature can be increased 40-50 C and the Heat Deflection temperature of PLLA can be increased from approximately 60 C to up to 190 C for by physically blending the polymer with PDLA (poly-D-lactide). PDLA and PLLA are known to form a highly regular stereocomplex with increased crystallinity. The maximum effect in temperature stability is achieved when a 50-50 blend is used, but even at lower concentrations of 3-10Prozent of PDLA a substantial effect is achieved. In the latter case PDLA is used as a nucleating agent, thereby increasing the crystallization rate. Due to the higher crystallinity of this stereo-complex, the biodegradability will become slower. The interesting feature is that the polymer blend remains transparent, which is one to the desirable properties that must be kept upon modification.
