Das Projekt "UBA EU-ETS-Handbuch" wird vom Umweltbundesamt gefördert und von Öko-Institut. Institut für angewandte Ökologie e.V. durchgeführt. Die Berichterstattung zur Emissionsentwicklung ist eine wichtige Säule der Klimapolitik. Sie ermöglicht zum einen den Fortschritt in Bezug auf die Klimaziele zu messen. Zum anderen kann die Wirksamkeit bestimmter Maßnahmen nur mit entsprechenden Daten beurteilt werden: Historische Daten sind für die Ex-post-Evaluierung unabdingbar, für die Ex-ante-Abschätzung kommen projizierte Daten und Modellierungsergebnisse dazu. Die verschiedenen Berichte/Datenquellen unterscheiden sich sowohl in Bezug auf den abgedeckten Zeitraum, die erfassten Emissionen sowie die verwendeten Klassifikationssysteme. Daher ist ein Vergleich der Daten und Datenkonzepte nicht immer leicht möglich. Ziel dieses Handbuchs ist es die Gemeinsamkeiten und Unterschiede der Datenkonzepte darzustellen und dadurch die Auswertungen zum stationären EU-Emissionshandel (EU-ETS) zu verbessern. Im Handbuch werden die Datenkonzepte im EU-ETS in Deutschland und der EU dargestellt. Die Abgrenzung des Emissionshandelssektors in anderen Berichtskategorien werden für das Treibhausgasinventar und im Vergleich zur Klassifikation der Wirtschaftszweige herausgearbeitet.
Das Projekt "E 4.1: Quality and food safety issues in markets for high-value products in Thailand and Vietnam" wird vom Umweltbundesamt gefördert und von Universität Hohenheim, Institut für Agrar- und Sozialökonomie in den Tropen und Subtropen durchgeführt. The production and marketing of high-value agricultural commodities - such as fruits, vegetables, and livestock products - has been an important source of cash income for small-scale farmers in the northern mountainous regions of Thailand and Vietnam. However, against the background of recent free trade agreements and market liberalization, there is increasing national and international competition, partly leading to significant price decreases. Given structural disadvantages of farmers in northern Thailand and Vietnam, it will be very difficult for them to achieve and maintain a competitive position in markets for undifferentiated high-value products. Therefore, product differentiation - in terms of health attributes (e.g., low-pesticide residues, free from diseases and pathogens), taste (e.g., indigenous livestock breeds), time (e.g., off-season production), or processing characteristics (e.g., packaging, drying, canning) - could be a promising alternative. Quality and safety attributes play an increasing role in domestic and international food trade. The additional value generated could lead to sustainable income growth in the small farm sector, but this potential will only materialize when appropriate institutional mechanisms help reduce transaction costs and allow a fair distribution of benefits. This subproject seeks to analyze how the production and marketing of high-value agricultural products with quality and safety attributes can contribute to pro-poor development in northern Thailand and Vietnam. Quality and safety attributes can only generate value when they directly respond to consumer demand. Furthermore, since they are often credence attributes, the product identity has to be preserved from farm to fork. Therefore, the analysis will cover the whole supply chain, from agricultural production to final household consumption. Interview-based surveys of farmers, intermediate agents, and consumers will be carried out in Thailand, and to a limited extent also in Vietnam. The data will be analyzed econometrically with regard to the structure of high-value markets, trends and their determinants, and efficiency and equity implications of different institutional arrangements (e.g., contract agriculture, supermarket procurement). Since in northern Vietnam, the marketing of high-value products is a relatively recent activity, markets for more traditional crops will be analyzed as well, to better understand the linkages between different cash-earning activities in the semi-subsistent farm households. Apart from their direct policy relevance, the results will contribute to the broader research direction of the economics of high-value agricultural markets in developing countries. Moreover, they will generate useful information for other subprojects of the Uplands Program.
Das Projekt "B 4.1: Land vulnerability and land suitability analysis in Northern Vietnam" wird vom Umweltbundesamt gefördert und von Universität Hohenheim, Institut für Bodenkunde und Standortslehre durchgeführt. As populations are steadily increasing in VN, farming land becomes scarce and new areas are opened up for cultivation, mainly in mountainous regions. On the fragile steep slopes deforestation and soil erosion are the well-known consequences. Land use in Yen Chau District, the study area in Son La, has significantly changed in the last decades. Until now, mainly soil degradation is reported on upland fields, but also soil erosion is increasing, both decreasing crop yields. In this project a database for topography, land use and soil properties within two subcatchments in Yen Chau will be created. The main goal of the project will be to carry out land suitability analysis and land vulnerability analysis, based on the data stored in the database, to provide tools for future sustainable land use planning. For this, a broad approach is intended by assessing land suitability for various crops, fruit trees and livestock production as well as to work out land vulnerability of the research area based on soil characteristics and topographic situation. The land suitability and vulnerability analysis will be carried out with the adopted SOTER (Soil and Terrain) approach. Normally used for a 1:500000 scale the SOTER technology will be developed for a 1:50.000 scale for two subcatchments. This is especially necessary because the closely cooperating projects C4.1 (Land use modelling), B5.1 (Water quality analysis) and G1.2 (Sustainability strategies) will rely on the spatial data of this scale. A totally new objective will be attempted by breaking down the SOTER technology to a scale of 1:5.000 for a village area in one of the selected subcatchments to regard the typical small-scale land use mosaic of a village area. Only with this scale the typical small scale land use mosaic of a village area can relatively precisely be mapped taking settlement areas, fish ponds, homegardens, fields, pastures, forests and scrubland as well as streams and creeks into account. With this approach it will be the first time possible to evaluate agricultural production on a village level using the SOTER technology. The SOTER database will be used with algorithms and soil transfer functions in order to derive soil suitability and soil vulnerability of certain areas. For the suitability analysis of different crops mainly the static approach for water regime, nutrient regime and potential root zone will be generated. As an important tool for decision making the erosion hazards due to water and especially gravity has to be visualized. As participatory soil mapping provides valuable additional information for land use evaluation and potential planning, this approach will be integrated on both the subcatchment and the village level in joint cooperation with A1.3 (Participatory Research). Finally, land use scenarios regarding different factors, e.g. change of cropping patterns, introduction of fruit trees, intensification of fish production or changes in market access, will be modelled.
Das Projekt "AZV Project West Greenland" wird vom Umweltbundesamt gefördert und von Universität Münster, Institut für Ökologie der Pflanzen durchgeführt. The AZV (Altitudinal Zonation of Vegetation) Project was initiated in the year 2002. On the basis of a detailed regional study in continental West Greenland the knowledge about altitudinal vegetation zonation in the Arctic is aimed to be enhanced. The main objectives of the project are: a) considering the regional study: characterize mountain vegetation with regard to flora, vegetation types, vegetation pattern and habitat conditions, investigate the differentiation of these vegetation characteristics along the altitudinal gradient, develop concepts about altitudinal indicator values of species and plant communities, extract suitable characteristics for the distinction and delimitation of vegetation belts, assess altitudinal borderlines of vegetation belts in the study area. b) considering generalizations: test the validity of the altitudinal zonation hypothesis of the Circumpolar Arctic Vegetation Map ( CAVM Team 2003), find important determinants of altitudinal vegetation zonation in the Arctic, develop a first small scale vegetation map of entire continental West Greenland. Field work consists of vegetational surveys according to the Braun-Blanquet approach, transect studies, soil analyses, long-time-measurements of temperature on the soil surface and vegetation mapping in three different altitudinal vegetation belts (up to 1070 m a.s.l.).
Das Projekt "B 3.1: Efficient water use of mixed cropping systems in watersheds of Northern Thailand highlands" wird vom Umweltbundesamt gefördert und von Universität Hohenheim, Institut für Kulturpflanzenwissenschaften (340), Fachgebiet Düngung und Bodenstoffhaushalt (340i) durchgeführt. Worldwide an important part of agricultural added value is produced under irrigation. By irrigation unproductive areas can be cultivated, additional harvests can be obtained or different crops can be planted. Since its introduction into Northern Thailand lychee has developed as one of the dominating cash crops. Lychee is produced in the hillside areas and has to be irrigated during the dry season, which is the main yield-forming period. Water therefore is mainly taken from sources or streams in the mountain forests. As nowadays all the available resources are being used do to increased production, a further increase in production can only be achieved by increasing the water use efficiency. In recent years, partial root-zone drying has become a well-established irrigation technique in wine growing areas. In a ten to fifteen days rhythm one part of the root system is irrigated while the other dries out and produces abscisic acid (ABA) a drought stress hormone. While the vegetative growth and thus labor for pruning is reduced, the generative growth remains widely unaffected. Thereby water-use efficiency can be increased by more than 40Prozent. In this sub-project the PRD-technique as well as other deficit irrigation strategies shall be applied in lychee and mango orchards and its effects on plant growth and yield shall be analyzed. Especially effects of this water-saving technology on the nutrient balance shall be considered, in order to develop an optimized fertigation strategy with respect to yield and fruit quality. As shown in preliminary studies, the nutrient supply is low in soils and fruit trees in Northern Thailand (e.g. phosphate) and even deficient for both micronutrients boron (B) and zinc (Zn). Additionally, non-adapted supply of nitrogen (mineralization, fertilization) can induce uneven flowering and fruit set. Therefore, improvement is necessary. For a better understanding of possible influence of low B and Zn supply on flowering and fruit set, mobility and retranslocation of both micronutrients shall be investigated for mango and lychee. Finally, the intended system of partial root-zone fertigation (PRF) shall guarantee an even flowering and a better yield formation under improved use of the limited resource water. As this modern technique, which requires a higher level of irrigation-technology, cannot be immediately spread among the farmers in the region, in a parallel approach potential users shall be integrated in a participative process for adaptation and development. Water transport and irrigation shall be considered, as both factors offer a tremendous potential for water saving. Local knowledge shall be integrated in the participatory process (supported by subproject A1.2, Participatory Research) in order to finally offer adapted technologies for application within PRF systems for the different conditions of farmers in the hillsides of Northern Thailand.
Das Projekt "Energy Storage for Direct Steam Solar Power Plants (DISTOR)" wird vom Umweltbundesamt gefördert und von Deutsches Zentrum für Luft- und Raumfahrt e.V., Institut für Technische Thermodynamik durchgeführt. Objective: Solar thermal power plants represent today's most economic systems to generate electricity from solar insulation in them-range in regions like the Mediterranean area. By demonstrating the feasibility of direct steam generation in the absorber pipes European industry and research institutions have gained a leading position in this technology area. A key element foray successful market penetration is the availability of storage systems to reduce the dependence on the course of solarinsolation. The most important benefits result from -reduced internal costs due to increased efficiency and extended utilisation of the power block-facilitating the integration of a solar power plant into an electrical grid-adoption of electricity production to the demand thus increasing revenues Efficient storage systems for steam power plants demand transfer of energy during the charging/discharging process at constant temperatures. The DISTOR project focuses on the development of systems using phase change materials (PCM) as storage media. In order to accelerate the development, the DISTOR project is based on parallel research on three different storage concepts. These concepts include innovative aspects like encapsulated PCM, evaporation heat transfer and new design concepts. This parallel approach takes advantage of synergy effects and will enable the identification of the most promising storage concept. A consortium covering the various aspects of design and manufacturing has been formed from manufacturers, engineering companies and research institutions experienced in solar thermal power plants and PCM technology. The project will provide advanced storage material based on PCM for the temperature range of 200-300 C adapted to the needs of Direct Steam generation thus expanding Europe's strong position in solar thermal power plants.
Das Projekt "Impact of transgenic crops on fertility of soils with different management history" wird vom Umweltbundesamt gefördert und von Forschungsinstitut für biologischen Landbau Deutschland e.V. durchgeführt. What impact does transgenic maize have on soil fertility? Among the factors that determine soil fertility is the diversity of the bacteria living in it. This is in turn affected by the form of agriculture practiced on the land. What role do transgenic plants play in this interaction? Background Soil fertility is the product of the interactions between the parental geological material from which the soil originated, the climate and colonization by soil organisms. Soil organisms and their diversity play a major role in soil fertility, and these factors can be affected by the way the soil is managed. The type of farming, i.e. how fertilizers and pesticides are used, has a major impact on the fertility of the soil. It is known that the complex interaction of bacterial diversity and other soil properties regulates the efficacy of plant resistance. But little is known about how transgenic plants affect soil fertility. Objectives The project will investigate selected soil processes as indicators for how transgenic maize may possibly alter soil fertility. The intention is in particular to establish whether the soil is better able to cope with such effects if it contains a great diversity of soil bacteria. Methods Transgenic maize will be planted in climate chambers containing soils managed in different ways. The soil needed for these trials originates from open field trials that have been used for decades to compare various forms of organic and conventional farming. These soils differ, for example, in the way they have been treated with pesticides and fertilizers and thus also with respect to their diversity of bacteria. The trial with transgenic maize will measure various parameters: the number of soil bacteria and the diversity of their species, the quantity of a small number of selected nutrients and the decomposition of harvest residues. It will be possible to conclude from this work how transgenic plants affect soil fertility. Significance The project will create an important basis for developing risk assessments that incorporate the effects of transgenic plants on soil fertility.
Das Projekt "Teilprojekt A" wird vom Umweltbundesamt gefördert und von Universität Gießen, Institut für Angewandte Mikrobiologie, Professur für Allgemeine und Bodenmikrobiologie durchgeführt. Wheat and barley production will be optimized under low energy input in organic farming at two experimental field stations of University Giessen and University Hohenheim. Effects of root densities (row distance), two nutrients fertilization regimes and seed inoculation of the plant growth promoting bacterium Hartmannibacter diazotrophicus will be analyzed in wheat as an important winter crop and in the summer crop barley. Quality parameters of produced grains differ for the two crops. For baking wheat protein quality and quantity is important while for malting barley high starch content is required. These parameter of the grains will be related to their root system and rhizosphere microbiome under the different treatments. The seed, root and rhizosphere bacterial and fungal microbiome will be analysed and it is expected to be specific for the two crop plants and less affected by the two soil types and locations. We aim to analyze the implication of root competition, nutrient limitation and seed inoculation on the microbiome under field conditions. Root competition will be analyzed using two different row distances under a low and optimal nitrogen fertilization regime. The plant root system might further profit from the inoculum and benefits would be derived from a more efficient root system that could capture N from fertiliser-soil sources more effectively, as well as more efficient N cycling might occur. Root architecture and biomass will be linked to microbiome analysis and grain quality and quantity. Before seeding and after harvest soil samples are analyzed for parameter estimating the sustainability of crop production. Such parameter include bacterial and fungal diversity, microbial respiration rate, soil N concentrations, protease and nitrification activity, phosphate concentration and phosphatase activity. Our results will be used for identification of optimal parameter for sustainable wheat and barley production and will lead to a bioeconomic evaluation.

Das Projekt "Improvement of oil palm wood by bio resin application" wird vom Umweltbundesamt gefördert und von Technische Universität Dresden, Fachrichtung Forstwissenschaften, Institut für Forstnutzung und Forsttechnik, Professur für Forstnutzung durchgeführt. Reinforcement of oil palm wood by using Bioresin to improve its physical, mechanical and machinery properties. Concerning the utilization of oil palm wood, which is available in large number throughout the year, especially when the mature plants has reached its economic life span (approx. 25 years). Normally, this mature plant should be replanting. According to the projection of oil palm plantation development in Indonesia, there are more than 16 million cubic meter of this bulky material starting 2010. This large amount of biomass, if no real effort, will become a serious problem. Unfortunately, the current replanting method (push-felled) sounds risky and in several companies follow by burning method, which is really not solve problem, but creating the other serious problem, such as air pollution. The oil palm wood characteristics as a monocotyledons species is naturally quite different compare to the common wood (dicotyledonous). Originally the oil palm tree has various densities along the trunk and its density decreased linearly with trunk height and towards the centre of the trunk. Green oil palm trunk is also very susceptible to fungal and insect attack due to the high sugar and starch content. Hence, the utilization of this material is not fully utilized yet and still poses a serious environmental problem. Yet, compared to the various intensive researches and the economically important of the oil palm, processing technology and diversification of palm oil based products mainly from CPO and PKO, the oil palm solid waste, particularly the oil palm wood, has received relatively little research attention. This might be due to lack or insufficient the scientific information and Know-How of this material and might be also due to the difficulties of using with the OPT. Although several investigations have already conducted in the field of OPT, but a sufficient knowledge shall be achieved in order to design and establish the new tailor-made wood products based on oil palm wood. Hence, this study was directed to focus the characteristics of OPT including anatomical, physical, mechanical and machinery properties, and in order to use the OPT for structural purposes, the wood properties of OPT were improved and reinforced with Bioresin through the development of wood modification techniques.
