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 "Phase 1: Earth and Space Based Power Generation Systems" wird vom Umweltbundesamt gefördert und von Deutsches Zentrum für Luft- und Raumfahrt, Institut für Technische Thermodynamik, Abteilung Systemanalyse und Technikbewertung durchgeführt. This study has to be understood in the frame of the global Energy Policy. A great part of world energy production is currently based on non-renewable sources: oil, gas and coal. Global warming and restricted fossil energy sources force a strong demand for another climate compatible energy supply. Therefore, fossil energy sources will nearly disappear until the end of this century. The question is to find a viable replacement. By using viable' it is meant a low-cost and environmental friendly energy. In other words, the question is to find an alternative to nuclear energy among all proposed but still not mature renewable energies. One of the solutions proposed is solar energy. Yet, two major concerns slow down its development as an alternative: first, it lacks of technological maturity and secondly it suffers from alternating supply during days and nights, winters and summers. The idea proposed by Glaser in the sixties to bypass this inconvenient is to take the energy at the source (or at least, as near as possible): in other words, to put a solar station on orbit that captures the energy without problems of climatic conditions and to redirect it through a beam to the ground. That is the concept of Solar Power Satellites. Its principal feasibility was shown by DOE / NASA in 1970 years studies (5 GW SPS in GEO). Project objectives: This phase 1 study activity is to be seen as the initial step of a series of investigations on the viability of power generation in space facing towards an European strategy on renewable, CO2 free energy generation, including a technology development roadmap pacing the way to establish in a step-wise approach on energy generation capabilities in space. The entire activity has to be embedded in an international network of competent, experienced partners. As part of this, an interrelationship to and incorporation of activities targeting the aims of the EU 6th FP ESSPERANS should be maintained. In particular, the activities related to following objectives are described: The generation of scientifically sound and objective results on terrestrial CO2 emission free power generation solutions in comparison with state-of-the-art space based solar power solutions The detailed comparison and trades between the terrestrial and the space based solutions in terms of cost, reliability and risk The identification of possible synergies between ground and space based power generation solutions The assessment on terrestrial energy storage needs by combining ground based with space based energy generation solutions The investigation of the viability of concepts in terms of energy balance of the complete systems and payback times.
Das Projekt "Further treatment of digested blackwater for extraction of valuable components and conversion to dry matter" wird vom Umweltbundesamt gefördert und von Technische Universität Hamburg-Harburg, Institut für Abwasserwirtschaft und Gewässerschutz B-2 durchgeführt. Phosphorus and nitrogen are valuable and should not be wasted or even worse recycled to the environment. An important resource in the sludge is nutrients which can be utilized through using sludge as fertilizer in the agriculture. Wastewater and excreta contain valuable nutrients that can be used in agriculture and aquaculture. Most of the nutrients, like phosphorous (P) and nitrogen (N), that a person consumes end up in the excreta. Nutrients are needed in developing countries as much as developed ones. Therefore, they should not be wasted. In nature there is no waste, all products of living things are used as raw materials by others (Esrey et al, 1998). Ecological sanitation systems (also called ecosan') are closed-loop systems, which treat human excreta as a resource. In this system, excreta are processed on site until they are free of pathogenic (disease-causing) organisms. Afterwards, sanitized excreta are recycled by using them for agricultural purposes. Key features of ecosan are therefore: - prevention of pollution and disease caused by human excreta; - treatment of human excreta as a resource rather than as a waste product; and - recovery and recycling of the nutrients. The problem of nutrient recovery from municipal sewage or excess sludge is not a new problem. In the literature, several papers have addressed the recovery of ammonia or phosphate from industrial and domestic wastewater, but not much with black water. So far many attempts have been made to control the process of self-deposition and recover nutrients as a fertilizer, which can be used directly for agricultural purposes as ecological sanitation advises. The aim of this research project is to find out further treatment methods of digested black water for extraction of valuable nutrients and convert them to dry matter and find solutions for dense urban areas and make usable compounds easier transportable.
Das Projekt "Ökologie des Wildschweins Sus scrofa in der Nähe von Schutzgebieten" wird vom Umweltbundesamt gefördert und von Universität Freiburg, Forstzoologisches Institut, Professur für Wildtierökologie und Wildtiermanagement durchgeführt. In strict nature reserves and core zones of protected areas hunting and forestry operations are often restricted or banned. However, regarding the management of Wild boar, such hunt-free zones are discussed controversially and can lead to conflict. Hunters whose areas border no-hunting zones (and who have to reimburse farmers for crop damages caused by Wild boar) are concerned that the boars may evade effective population management by staying within the limits of the no-hunting zone, and farmers fear increased crop damage in the surroundings of such areas. Some conservationists are also concerned because Wild boars increasingly root protected habitats and can cause damage to rare plant assemblies. The three-year project Wild boar problem in the vicinity of protected areas by the Game Research Institute (Wildforschungsstelle) at the Centre for Agriculture Baden-Württemberg (LAZBW) aims at investigating if and how no-hunting zones might affect Wild boar activity, movement patterns, home range size, and habitat use, as well as crop damage caused by boars, by comparing these aspects between hunting-free zones and unprotected areas. Although there have already been a number of telemetry studies on Wild boar, including space use in the context of hunting activity, to date there is no study that has specifically investigated spatial and ecological aspects in and around protected areas. My dissertation Ecology of Wild boar Sus scrofa in the vicinity of protected areas is being carried out within the scope of the Game Research Institutes project and apart from the aims outlined above, further aspects of Wild boar ecology will be investigated, especially the role of Wild boar as bio-engineer and habitat creator for other species vs. unwanted damages at protected sites. Twenty-seven Vectronic GPS-GSM satellite collars with integrated activity sensors are available to tag Wild boars in three study areas: the non-protected Altdorfer Forest near Aulendorf with regular hunting activity and forestry, the nature reserve Wurzacher Ried with its ca. 700 ha core zone that is a strict reserve with no human activity, and the Biosphere Reserve Swabian Jura, especially in the surroundings of the former military training area near Münsingen and the 170 ha no-usage-area Föhrenberg.
Das Projekt "Effects of elevated CO2 concentrations on carbon turnover in crop rotations studied in a Chinese and a German free air carbon dioxide enrichment (FACE) approach" wird vom Umweltbundesamt gefördert und von Johann Heinrich von Thünen-Institut Bundesforschungsinstitut für Ländliche Räume, Wald und Fischerei - Institut für Biodiversität durchgeführt. Die Böden der Welt sind die größten terrestrischen Kohlenstoffspeicher. Die rasch zunehmende CO2-Konzentration in der Atmosphäre wird die ober- und unterirdische Biomasseproduktion von Pflanzen stimulieren. Insbesondere in Agrarökosystemen sind bislang Rückkoppelungswirkungen des CO2-Anstieges auf den Corg-Gehalt in Böden bzw. auf die Bindung und Freisetzung von CO2 und damit auf den atmosphärischen CO2-Gehalt noch nicht ausreichend abschätzbar. Eine entscheidende Rolle spielt dabei der mikrobielle Umsatz des C in Böden. Diskutiert wird sowohl eine mögliche Beschleunigung des C- bzw. CO2-Umsatzes durch den vermehrten Anfall leicht verfügbarer C-Verbindungen im Boden, als auch eine Reduktion der Mineralisierungsdaten, die aus einem verzögerten Abbau von Pflanzenresten mit einem durch die CO2-Erhöhung verursachten größeren C:N-Verhältnis resuliert. Freiland-CO2-Anreicherungsversuche in ackerbaulich genutzten Systemen unter Verwendung der sog. Free Air Carbon Dioxide Enrichment (FACE) Technik existieren z.Z. nur in China und in Deutschland. Das vorliegende Projekt wird diese einzigartigen Versuchsansätze der beiden Projektpartner nutzen und die Wirkungen erhöhter CO2-Konzentrationen auf die ober- und unterirdische Biomassebildung der Fruchtfolgeglieder, auf die in situ Bodenatmung, auf den mikrobiellen Biomassegehalt der Böden einschließlich des respiratorischen Quotienten der mikrobiellen Biomasse sowie auf die Mineralisierungsraten von Pflanzenresten untersuchen. Gleichzeitig wird der Einfluss einer unterschiedlichen Stickstoff-Düngung überprüft. Das Projekt dient neben einem Methodenvergleich der Bewertung des Einflusses von unterschiedlichen Bodeneigenschaften und Klimaverhältnissen auf die CO2-Wirkung. Die experimenellen Daten sollen zur Verbesserung eines Modells zur Beschreibung des C- und N-Umsatzes in Böden beitragen.
