Das Projekt "Developing a model for sustainable water and waste management for rural areas in Bulgaria" wird vom Umweltbundesamt gefördert und von Technische Universität Hamburg-Harburg, Institut für Abwasserwirtschaft und Gewässerschutz B-2 durchgeführt. The Municipalities of Stara Zagora and Varna will be the targets for a 2,5 year project by WECF and its NGO partners from Bulgaria and the Netherlands; the Earth Forever Foundation, the Institute of Ecological Modernization and WASTE and IRC Netherlands. The project receives financial support from the Netherlands Ministry of Foreign Affairs MATRA programme. The Institute of Wastewater Management (TUHH) is supporting this project with respect to the introduction of ecological sanitation and extensive wastewater treatment technologies like planted soil filters. Workshops are given and technical knowledge regarding the design, construction and operation of these facilities is provided. This will help to improve the current situation in the villages and will provide an example for further distribution of appropriate wastewater management in Bulgarian villages. Currently, only a very small part of the population is connected to a central sewer system, which discharges the wastewater without any further treatment into the environment. The remaining families are depending on outdoor pit latrines, soakaways and septic tanks which are very often subject to clogging. Thus, overflowing and discharging of wastewater onto streets is a very common problem.
Das Projekt "DE-LIGHT Transport" wird vom Umweltbundesamt gefördert und von Center of Maritime Technologies e.V. durchgeführt. 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.
Das Projekt "Electrification through Micro Hydro Power Sites in Rural Indonesia" wird vom Umweltbundesamt gefördert und von Rheinisch-Westfälisches Institut für Wirtschaftsforschung e.V. RWI, Kompetenzbereich Umwelt und Ressourcen durchgeführt. While urban Indonesia is almost completely electrified, two-thirds of the rural population still lack access to electricity. In many cases, the mountainous rural areas are difficult to access and sparsely populated implying high investment costs for infrastructure extension. Against this background the German International Cooperation (GIZ) supports the implementation of micro hydro plants (MHP) in rural communities to supply the population with decentralized electricity. During its first project phase between 2006 and 2009, GIZ has supported the construction of 96 MHPs on two of the five main islands of Indonesia, Sulawesi and Sumatra. These activities have been funded as part of the Dutch-German Energy Partnership Energising Development (EnDev), an output-oriented programme that aims at providing modern energy to 6.1 million people in 21 countries. In a second project phase starting in 2010 (EnDev II), more than 200 micro-hydro schemes are planned to be supported. RWI has been assigned to assess the socio-economic impacts of electrification through MHP on household level through both a cross-sectional and a difference in differences approach. For this purpose, 800 households were interviewed in a first survey wave in September and November 2010. Half of them are located in 20 EnDev II villages that only got connected to an MHP after data collection. The remainder of the sample has already been using electricity at that time from a working micro hydro scheme supported within EnDev I. The second survey wave is scheduled for autumn 2012. The cross-sectional arm of the study allowed for gauging the impacts of the connection to an MHP already after the first wave at the end of 2010. For the electrified, hence, treated EnDev I households, comparable EnDev II households have been used as controls. Having follow-up data at hand at the end of 2012, difference in differences estimators can be applied to more rigorously assess the impacts of the connection to an MHP. In this approach, the EnDev I households already connected in 2010 and still connected in 2012 will serve as a reference group for the EnDev II households who got treated between the 2010 and 2012 survey. This prevents that changes induced by external influences (e.g. general economic development) are falsely ascribed to the treatment. For the reference group of EnDev II households it was found in 2010 that an important share already used 'pre-electrification' sources like generators or very simple traditional waterwheels - so called kincirs. The impact assessment will therefore not only illustrate the change from traditional energy sources like kerosene to electricity but also deliver impact findings on using a modern electricity source in comparison to pre-electrification sources that tend to be either costly and dirty (generators), or unstable and weak (kincir).
Das Projekt "Bau der großen Windenergieanlage GROWIAN mit einer elektrischen Leistung von 3 MW" wird vom Umweltbundesamt gefördert und von Grosse Windenergieanlage Bau- und Betriebsgesellschaft durchgeführt. Sowohl die bisher gewonnenen Erkenntnisse und Erfahrungen mit Windkonvertern kleinerer und mittlerer Leistungen im In- und Ausland als auch die Ergebnisse mehrerer dem Projekt GROWIAN vorausgegangener FE-Vorhaben ließen erkennen, dass ein (großtechnischer Versuch zur additiven Erzeugung von elektrischem Strom aus Windenergie mit Leistungen zwischen 2000 und 3000 kW als realisierbar einzuschätzen war. So wurde folgerichtig der Entschluss gefasst, das Projekt GROWIAN in einer Prototypanlage zu verwirklichen, auch wenn mit der vorgegebenen Bemessung -Turmhöhe 100m/Rotor Durchmesser, 100m/Nennleistung 3000 kW- diese Größenordnung derzeit ohne Vorbild war, sodass in vielen Fällen technisches Neuland betreten werden musste. Zielsetzung: Die Projektierung, Konstruktion, Errichtung und Erprobung sollen zur Verwirklichung der Einzelentwicklung von (Anlagekomponenten und -systemen durchgeführt werden. Die damit gewonnenen Erkenntnisse sollen neben der Feststellung der Bauaufwendungen die Beurteilung der Realisierbarkeit und Wirtschaftlichkeit einer Stromerzeugung in großen Windenergieanlagen ermöglichen. Ergebnis: Ungeachtet der Frage der Lebensdauer und der festgestellten Bauaufwendungen hat die Anlage die in sie gesetzten Erwartungen voll erfüllt.

Das Projekt "Bau von zwei Windkraftanlagen AEROMAN 11/11 für Indonesien" wird vom Umweltbundesamt gefördert und von Maschinenfabrik Augsburg-Nürnberg, Bereich Neue Technologie durchgeführt. Das Vorhaben wurde im Rahmen der deutsch-indonesischen Kooperation auf dem Gebiet der wissenschaftlichen Forschung und technologischen Entwicklung durchgeführt. Hierbei sollte der indonesische Partner kurzfristig in den Bau moderner Windkraftanlagen eingearbeitet werden. Bei der Lieferung der beiden Anlagen stand die Nutzung der erzeugten Energie mit im Vordergrund. Es wurde ein Konzept für den Betrieb von Eiserzeugungsanlagen ohne Zwischenspeicherung der elektrischen Energie erstellt. Die Ergebnisse aus dem Testbetrieb zeigten, dass die realisierte Betriebskonzeption voll funktionstüchtig ist. Nach entsprechender Ausbildung war der indonesische Partner in der Lage, die Windkraftanlagen selbständig zu installieren.
Das Projekt "Stratospheric ozone: halogen impacts in a varying atmosphere (SHIVA)" wird vom Umweltbundesamt gefördert und von Universität Heidelberg, Institut für Umweltphysik durchgeführt. 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.
Das Projekt "Problems of legitimacy in the development of forestry institutions" wird vom Umweltbundesamt gefördert und von Universität Freiburg, Institut für Forst- und Umweltpolitik durchgeführt. The typological approach to the prize winning pictures in photo contests in Europe an Japan. The existence of the Foucauldian archive of collective memry in landscape is examed by analyzing the result of the contests from wider socio-cultural context. The social construction of nation as volks of forests is believed to be very unique phenominon but the process could be very similar in different contexts.
Das Projekt "Scientific Support for Regional Downscaling of Precipitation and Temperature Data for Climate Change Impact Assessment in the Nile Equatorial Lakes Region" wird vom Umweltbundesamt gefördert und von Universität Stuttgart, Institut für Wasserbau durchgeführt. 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.
