Das Projekt "The European aeroemissions network (AERONET)" wird vom Umweltbundesamt gefördert und von Deutsches Zentrum für Luft- und Raumfahrt e.V., Institut für Antriebstechnik durchgeführt. One of the major problems that civil aeronautics will have to face over the next twenty or thirty years is to accommodate the predicted growth in demand of air transport without creating unacceptable adverse environmental effects. It is to be expected that new scientific results, increasing public concerns over the environment and future restrictive regulations with respect to aircraft emissions will force airline companies to take ecological considerations much more into account than it does at present. Consequently, for European aircraft manufacturers it is of high importance to react early and to guide their research and development resources into the most important and efficient direction. The aim of the AERONET project is to support coordination ' a postiori' of existing European and national projects or programmes dealing with the contribution of air traffic emissions to anthropogenic climate and atmospheric changes. For this purpose AERONET seeks to : - bring together experts from engine technology, atmospheric research and operations as well as programme responsible to exchange knowledge and opinions and to discuss necessary future actions on the basis of jointly defined goals and time scales, - produce competitive advantage for Europe through enhanced information echoing in the field of atmospheric effects of air traffic emissions, - strengthen a common European position in global technical and political discussions - support the Commission in identifying topics for the 5th Framework Programme, - identify gaps and help prepare a coordinated submission of proposals. European Dimension and Partnership: Europe is, beside the US, one of the two biggest aircraft manufacturers. One supposition for the economic success of European aircraft industry is not only to fulfill the existing regulations but, due to the long development times of 5-10 years and the long lifetimes of aircraft of more than 20 years, also to take the trend of future regulations development into account at a very early stage. This needs continuous and fast information exchange and discussions between atmospheric scientists, aircraft engineers and regulatory organisations. To be successful with an effort of this dimension, optimal coordination of national and European programmes in all three fields is required. Thus the network brings together representatives of all programmes and institutions concerned, helps to integrate activities through better information exchange, tries to identify the most urgent themes for R&D activities and intends to give recommendations for the Fifth Framework Programme. Potential Applications: Understanding the atmospheric impacts, the technical consequences and development perspectives, and the operational impacts as a whole is absolutely necessary to strengthen the European position in global regulatory committees on the on side and to gain competitive advantages for the European aircraft and airline industries on the other side. usw
Das Projekt "Impacts of Solar Home System Usage in Rural Burkina Faso" wird vom Umweltbundesamt gefördert und von Rheinisch-Westfälisches Institut für Wirtschaftsforschung e.V. RWI, Kompetenzbereich Umwelt und Ressourcen durchgeführt. In remote areas with low electrification rates, Solar Home Systems (SHS) can be seen as a promising alternative to the investment-intensive extension of the electricity grid. The Dutch Ministry of Foreign Affairs provides funding to a project in Burkina Faso that offers SHS to rural households using a market-based approach. The SHS that are distributed can provide electric lighting and - depending on the chosen capacity of the system - allow for the usage of small electric appliances up to colored television. As part of the series of impact evaluations of development activities supported by the Netherlands on behalf of the Dutch Ministry of Foreign Affairs, RWI and ISS assess the socio-economic impact of the usage of SHS such as improved living conditions, time savings, increased security, better health conditions, and educational attainment trough extended study hours. The idea is to conduct a difference-in-difference approach based on household surveys before and after the intervention, in combination with propensity score matching (PSM) to better match control and treatment households on pre-program characteristics (e.g. education, socio-economic status, income, asset-ownership, characteristics of the villages they live in). Following the roll-out plan of Yeelen Ba's activities, a baseline survey was conducted in November 2010 based on a random sample of villages that are in the program's catchment area. In total, 1,200 households in 40 villages (30 households per village) were interviewed. A particular focus was on the use of appliances and energy expenditures, as well as convenience and comfort aspects before and after the SHS was installed. For the difference-in-difference approach the sample will be divided into a treatment group consisting of households who will have obtained an SHS in the meantime and a control group consisting of untreated households. The follow-up survey will be conducted two years after the baseline survey in November 2012. All households will be revisited and differences in the changes in the outcome variables between the treatment group and the control group will be assessed, providing insights about how ownership of an SHS changes the socio-economic living conditions of the households.
Das Projekt "Forest management in the Earth system" wird vom Umweltbundesamt gefördert und von Max-Planck-Institut für Meteorologie durchgeführt. The majority of the worlds forests has undergone some form of management, such as clear-cut or thinning. This management has direct relevance for global climate: Studies estimate that forest management emissions add a third to those from deforestation, while enhanced productivity in managed forests increases the capacity of the terrestrial biosphere to act as a sink for carbon dioxide emissions. However, uncertainties in the assessment of these fluxes are large. Moreover, forests influence climate also by altering the energy and water balance of the land surface. In many regions of historical deforestation, such biogeophysical effects have substantially counteracted warming due to carbon dioxide emissions. However, the effect of management on biogeophysical effects is largely unknown beyond local case studies. While the effects of climate on forest productivity is well established in forestry models, the effects of forest management on climate is less understood. Closing this feedback cycle is crucial to understand the driving forces behind past climate changes to be able to predict future climate responses and thus the required effort to adapt to it or avert it. To investigate the role of forest management in the climate system I propose to integrate a forest management module into a comprehensive Earth system model. The resulting model will be able to simultaneously address both directions of the interactions between climate and the managed land surface. My proposed work includes model development and implementation for key forest management processes, determining the growth and stock of living biomass, soil carbon cycle, and biophysical land surface properties. With this unique tool I will be able to improve estimates of terrestrial carbon source and sink terms and to assess the susceptibility of past and future climate to combined carbon cycle and biophysical effects of forest management. Furthermore, representing feedbacks between forest management and climate in a global climate model could advance efforts to combat climate change. Changes in forest management are inevitable to adapt to future climate change. In this process, is it possible to identify win-win strategies for which local management changes do not only help adaptation, but at the same time mitigate global warming by presenting favorable effects on climate? The proposed work opens a range of long-term research paths, with the aim of strengthening the climate perspective in the economic considerations of forest management and helping to improve local decisionmaking with respect to adaptation and mitigation.
Das Projekt "C3: Market inclusion of ecosystem services: A viable option to achieve sustainable land use in the tropics?" wird vom Umweltbundesamt gefördert und von Technische Universität München, Wissenschaftszentrum Weihenstephan für Ernährung, Landnutzung und Umwelt, Fachgebiet für Waldinventur und nachhaltige Nutzung durchgeführt. The concept of ecosystem services (ES) links ecosystem functioning and human wel-fare to achieve sustainable land use. However, the success of this concept will critically depend on sources to finance the provision of ES (possibly mobilized by means of markets for ES), on credibility of ES values and on willingness of ES providers to ac-cept financial compensation. Our proposal addresses these aspects: The first part investigates how the land use in Ecuador would change if ES were actually acknowl-edged as economic values. We will use and develop a risk sensitive economic modeling approach to integrate the uncertainty of expected economic values for ES. The aim is to explore how the uncertainty of ES values would affect investments into specific ecosystem types and the connected conversion processes from tropical forest lands to other land use types and vice versa. The second proposal part investigates the willing-ness to accept financial compensation for providing ES. In this part we adapt a risk-sensitive bioeconomic farm model that combines various productive but sustainable land management options to real farm situations. The farm level modeling builds upon the effects of risk compensation from diversified land use by means of a land use port-folio approach. It will be used to derive acceptable individual and thus effective conser-vation payments.
Das Projekt "Fuel-Switch Project in the North-West of Russia" wird vom Umweltbundesamt gefördert und von GFA Envest GmbH durchgeführt.

Das Projekt "E 1.2: Multi-layer drying models for optimising high value crop drying in small scale food industries" wird vom Umweltbundesamt gefördert und von Universität Hohenheim, Institut für Agrartechnik, Fachgebiet Agrartechnik in den Tropen und Subtropen durchgeführt. Fruit tree cultivation is a suitable option for erosion control in mountainous regions of Southeast Asia. However, seasonal overproduction and insufficient access to markets can cause economic losses. The possibility of processing fruits locally could contribute considerably to increase and stabilize farm income. Currently, fruit drying methods in these areas are yielding products of inferior quality. Pre-treatments such as sulphurizing are commonly used, but can make the product undesirable for international markets. In addition, high energy requirements increase production costs significantly. Therefore, the objective of subproject E1.2 is to optimize the drying process of small-scale fruit processing industries in terms of dryer capacity, energy consumption and efficiency and end product quality. During SFB-phase II in E1.1, drying fundamentals for the key fruits mango, litchi and longan were established. In laboratory experiments, impacts of drying parameters on quality were investigated and numerical single-layer models for simulation of drying kinetics have been designed. In SFB-phase III this knowledge will be expanded with the aim of optimizing practical drying processes. Therefore, the single-layer models will be extended to multi-layer models for simulating bulk-drying conditions. The Finite Element Method (FEM) will be adapted to calculate heat and mass transfer processes. Thermodynamic behavior of batch and tray dryers will be simulated using Computational Fluid Dynamics (CFD) software. Drying facilities will be optimized by systematic parameter variation. For reduction of energy costs, the potential of solar energy and biomass will be investigated in particular. Further research approaches are resulting from cooperation with other subprojects. A mechanic-enzymatic peeling method will be jointly used with E2.3 for studying the drying behavior of peeled litchi and longan fruits. Furthermore, a fruit maturity sensor based on Acoustic Resonance Spectroscopy (ARS) will be developed in cooperation with E2.3 and B3.2. Finally, an internet platform will be built for exchange of farmer-processor information about harvest time and quantities to increase utilization of the processing facilities.
Das Projekt "Calcium cycle for efficient and low cost CO2 capture in fluidized bed systems (C3-CAPTURE)" wird vom Umweltbundesamt gefördert und von Universität Stuttgart, Fakultät für Energietechnik, Institut für Verfahrenstechnik und Dampfkesselwesen durchgeführt. Objectives: The project aims on developing a dry CO2 capture system for atmospheric and pressurized fluidized bed boilers. The atmospheric option will be developed towards a pilot plant application. For the pressurized option the project seeks for a proof of principle to determine if the advantages of a pressurized capture system can balance the problems known from existing PFBC systems. The quantifiable objectives are: - Low CO2 capture costs (less than 20 Euro/t for atmospheric, less than 12 Euro/t for pressurized sy stems) - Acceptable efficiency penalty for CO2 capture (less than about equal to 6 percent nel). - greater than 90 percent carbon capture for new power plants and greater than 60 percent for retrofitted existing plants - A purge gas stream containing greater than 95 percent CO2 - A solid purge usable for cement production - Sim ultaneous sulphur and CO2 removal with sulphur recovery option Approach: Limestone is a CO2 carrier. The CO2 can be released easily in a conventional calcination process, well known in the cement and lime industry. By integrating a closed carbonation/calc ination loop in the flue gas of a conventional CFB-boiler, the CO2 in the flue gas can be removed. The heat required for calcination is released during carbonation and can be utilised efficiently (high temperature) in the steam cycle of the boiler. Concent rated CO2 can be generated when using oxygen blown calcination. Because the fuel required for supplying heat for calcination is only a fraction of the total fuel requirements, the required oxygen is only about 1/3 of the oxygen required for oxyfuel process es. The work programme: 1.Definition of the technical and economic boundary conditions 2.Selection and improvement of sorbent materials 3.Lab scale and semi-technical scale process development (experimental work) 4.Technical and economic evaluation 5.Des ign of a 1 MWth Pilot plant.
Das Projekt "MYFISH - Maximising yield of fisheries while balancing ecosystem, economic and social concerns" wird vom Umweltbundesamt gefördert und von Universität zu Kiel, Institut für Volkswirtschaftslehre, Lehrstuhl für Umwelt-, Ressourcen- und Ökologische Ökonomik durchgeführt. The MSY concept was included as a principle in the 2009 Green Paper on the reform of the Common Fisheries Policy (CFP) in accordance with the global imperative to manage fish stocks according to the maximum sustainable yield (MSY). This implies a commitment to direct management of fish stocks towards achieving MSY by 2015. Attaining this goal is complicated by the lack of common agreement on the interpretation of 'sustainability' and 'yield' and by the effects that achieving MSY for one stock may have on other stocks and broader ecosystem, economic, or social aspects. MYFISH will provide definitions of MSY variants which maximize other measures of 'yield' than biomass and which account for the fact that single species rarely exist in isolation. Further, MYFISH will redefine the term 'sustainable' to signify that Good Environmental Status (MSFD) is achieved and economically and socially unacceptable situations are avoided, all with acceptable levels of risk. In short, MYFISH aims at integrating the MSY concept with the overarching principals of the CFP: the precautionary and the ecosystem approach. MYFISH will achieve this objective through addressing fisheries in all RAC areas and integrating stakeholders (the fishing industry, NGOs and managers) throughout the project. Existing ecosystem and fisheries models will be modified to perform maximization of stakeholder approved yield measures while ensuring acceptable impact levels on ecosystem, economic and social aspects. Implementation plans are proposed and social aspects addressed through active involvement of stakeholders. Finally, effects of changes in environment, economy and society on MSY variants are considered, aiming at procedures rendering the MSY approach robust to such changes. The expertise of 26 partners from relevant disciplines including fisheries, ecosystem, economic and social science are involved in all aspects of the project. Global experience is engaged from North America and the South Pacific.
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 "TRansitions to the Urban Water Services of Tomorrow (TRUST)" wird vom Umweltbundesamt gefördert und von IWW Rheinisch-Westfälisches Institut für Wasserforschung gemeinnützige GmbH durchgeführt. The European project initiative TRUST will produce knowledge and guidance to support TRansitions to Urban Water Services of Tomorrow, enabling communities to achieve sustainable, low-carbon water futures without compromising service quality. We deliver this ambition through close collaboration with problem owners in ten participating pilot city regions under changing and challenging conditions in Europe and Africa. Our work provides research driven innovations in governance, modelling concepts, technologies, decision support tools, and novel approaches to integrated water, energy, and infrastructure asset management. An extended understanding of the performance of contemporary urban water services will allow detailed exploration of transition pathways. Urban water cycle analysis will include use of an innovative systems metabolism model, derivation of key performance indicators, risk assessment, as well as broad stakeholder involvement and an analysis of public perceptions and governance modes. A number of emerging technologies in water supply, waste and storm water treatment and disposal, in water demand management and in the exploitation of alternative water sources will be analysed in terms of their cost-effectiveness, performance, safety and sustainability. Cross-cutting issues include innovations in urban asset management and water-energy nexus strengthening. The most promising interventions will be demonstrated and legitimised in the urban water systems of the ten participating pilot city regions. TRUST outcomes will be incorporated into planning guidelines and decision support tools, will be subject to life-cycle assessment, and be shaped by regulatory considerations as well as potential environmental, economic and social impacts. Outputs from the project will catalyse transformation change in both the form and management of urban water services and give utilities increased confidence to specify innovative solutions to a range of pressing challenges.
