Background: Ghanas transition forests, neighbouring savannahs and timber plantations in the Ashanti region face a constant degradation due to the increased occurrence of fires. In most cases the fires are deliberately set by rural people for hunting purposes. Main target is a cane rat, here called grasscutter (Thryonomys swinderianus), whose bushmeat is highly esteemed throughout the country. The animal is a wild herbivorous rodent of subhumid areas in Africa south of the Sahara. The grasscutter meat is an important source of animal protein. Existing high-value timber plantations (mainly Teak, Tectona grandis) are affected by fires for hunting purposes. Thus resulting in growth reduction, loss of biomass or even complete destruction of the forest stands. It became obvious that solutions had to be sought for the reduction of the fire risk. Objectives: Since 2004 the Institute for World Forestry of the Federal Research Centre for Forestry and Forest Products, Hamburg, Germany is cooperating with a Ghanaian timber plantation company (DuPaul Wood Treatment Ltd.) the German Foundation for Forest Conservation in Africa (Stiftung Walderhaltung in Afrika) and the Center for International Migration with the purpose to improve the livelihood of the rural population in the surroundings of the forest plantation sites and simultaneously to safeguard and improve the timber plantations. The introduction of grasscutter rearing systems to local farmers accompanied by permanent agricultural and agroforestry practices appeared to be a promising approach for the prevention of fires in the susceptible areas. Additionally a functioning grasscutter breeding system could contribute to the improvement of food security, development of income sources and the alleviation of poverty. The following measures are implemented: - Identification of farmers interested in grasscutter captive breeding, - Implementation of training courses for farmers on grasscutter rearing, - Delivery of breeding animals, - Supervision of rearing conditions by project staff, - Development of a local extension service for monitoring activities, - Evaluation of structures for grasscutter meat marketing. Results: After identification of key persons for animal rearing training courses were successfully passed and animals were delivered subsequently. Further investigations will evaluate the effects of the grasscutter rearing in the project region. This will be assessed through the - Acceptance of grasscutter rearing by farmers, - Success of the animal caging, - Reproduction rate, - Meat quality, - Marketing success of meat, - Reduction of fire in the vicinity of the timber plantations, - Improvement of peoples livelihood.
Background: An increasing frequency of massive flooding along the lower Yangtse River in China ended in a disastrous catastrophe in summer 1998 leaving several thousand people homeless, more than 3.600 dead and causing enormous economic damage. Inappropriate land-use techniques and large scale timber felling in the water catchment of the upper Yangtse and its feeder streams were stated to be the main causes. Immediate timber cutting bans were imposed and investigations on land use patterns were initiated by the Chinese Government. The Institute for World Forestry of the Federal Research Centre for Forestry and Forest Products was approached by the Yunnan Academy of Forestry in Kunming to exchange experiences and to cooperate scientifically in the design and application of appropriate afforestation and silvicultural management techniques in the water catchment area of the Yangtse. This cooperation was initiated in 1999 and is based on formal agreements in the fields of agrarian research between the German and Chinese Governments. Objectives: The cooperation was in the first step focussing on the identification of factors which caused the enormous floodings. After their identification measures of prevention were determined and put into practice. In this context experiences made in past centuries in the alpine region of central Europe served as an incentive and example for similar environmental problems and solutions under comparable conditions. Relevant key questions of the cooperation project were: - Analysis of forest related factors influencing the recent floodings of the Yangtse, - Analysis and evaluation of silvicultural management experiences from central Europe for know-how transfer, - Evaluation of rehabilitation measures for successful application in Yunnan, - Dissemination of knowledge through vocational training. Results: - Frequent wild grazing of husbandry is a key factor for forest degeneration beyond unsustainable timber harvests, forest fires and insect calamities leading to increased water run-off in the mountainous region of Yunnan; - Browsing of cattle interrupts succession thus avoiding natural regeneration and leaving a logging ban ineffective; - Mountain pasture in the Alps had similar effects in the past in central Europe. The introduction of controlled grazing has led to an ecologically compatible coexistence of pasture and ecology. Close-to-nature forestry can have positive effects in this sensitive environment. - Afforestation with site adopted broadleaves and coniferous tree species was implemented on demonstration level using advanced techniques in Yunnan.
Zusammensetzung und Menge der organischen Bodensubstanz (OBS) werden durch die Landnutzungsform beeinflußt. Die OBS läßt sich nach ihrer Abbaubarkeit und nach ihrer Löslichkeit in verschiedene Pools einteilen. So kann die wasserlösliche organische Bodensubstanz (DOM) als Maßzahl für die abbaubare OBS herangezogen werden. Mit Natriumpyrophosphat-Lösung als Extraktionsmittel läßt sich ein weit größerer Anteil der OBS erfassen, da der stabilisierende Bindungsfaktor zwischen OBS und Bodenmineralen entfernt wird. Extrahiert man zuerst mit Wasser und anschließend mit Natriumpyrophosphat-Lösung, erhält man im letzten Schritt den schwer abbaubaren OBS-Anteil. Über die funktionelle Zusammensetzung der organischen Substanz dieser Pools und deren Abhängigkeit von Landnutzungsformen ist relativ wenig bekannt. Ziel der geplanten Untersuchung ist es, den Pool der löslichen abbaubaren und schwer abbaubaren OBS zu quantifizieren und deren funktionelle Zusammensetzung mittels FT-IR Spektroskopie zu erfassen. Die so gewonnenen Daten sollen der Validierung von Soil Organic Matter Turnover modellen (z.B. Roth 23.6) dienen und die im Modell berechneten Pools um einen qualitativen Term ergänzen. In Zusammenarbeit mit anderen Arbeitsgruppen sollen im DFG-Schwerpunktprogramm 1090: ;Böden als Quelle und Senke für CO2 die Pools der löslichen abbaubaren und schwer schwer löslichen, schwer abbaubaren organischen Bodensubstanz (OBS) quantifiziert, die funktionelle Zusammensetzung dieser Pools mittels FT-IR Spektroskopie erfasst und Abbaubarkeit der erhaltenen Extrakte überprüft werden, um Mechanismen, die zur Stabilisierung der OBS führen, aufzuklären.
The scope of sewage treatment is changing: Up to date municipal wastewater treatment plants (WWTP) were seen as an end-of-pipe treatment just before discharge, having the aim to avoid eutrophication and hygienic health hazard in surface water. Due to the global demographic trends as well as new legislations (e.g. the Water Framework Directive, WFD) increased focus is put on quantity and quality of effluents: WWTP are more and more seen as interface between sanitation and environment, delivering resources to the environment or human activities (recharge of drinking water reservoirs, recycling of nutrient, efficient energy use). This focus shift has implications on the quality goals set for WWTP products: land requirement, effluent N, P load, effluent pathogen load, energy optimization. New focus: nutrient recycling, micropollutants: ecotoxicology of the effluent energy production. NEPTUNE is focusing on technology solutions allowing to meet present and future standards via upgrading of existing infrastructure (new control strategies with online sensors; effluent upgrading with oxidation, activated carbon or wetland treatment; sludge processing for safe nutrient recycle) as well as via new techniques (fuel cell applications; new oxidative agents; polymer production from sludge). By including pathogen and ecotoxicity aspects into life cycle assessment studies (LCA), the project is helping improve the comparability of various technical options and propose a suitability ranking. The new focus given by the WFD and the emerging interest on organic (eco-)toxic compounds requires characterizing treated effluent and treatment technologies concerning ecotoxicologic aspects and micropollutants. The project is contributing to this discussion by ecotoxicity assessment and micropollutant fate studies.
Wirksame Maßnahmen zum Gewässerschutz, wie sie von der EG-Wasserrahmenrichtlinie als Bestandteil des nachhaltigen Land- und Wassermanagements gefordert werden, setzen fundierte Kenntnisse zu Stoffretentions- und -umsatzprozessen in Landschaften voraus. Vergleiche von Stoffaus- und -einträgen wie auch mit den Fließgewässern ausgetragene Frachten belegen das hohe Stoffretentionspotenzial pleistozäner Einzugsgebiete und Fließgewässersysteme. Forschungsbedarf besteht zur Quantifizierung und Modellierung der dafür auf Landschaftsebene maßgeblichen Transport- und Transformationsprozesse unter den durch Wechselfeuchte und Wassermangelperioden gekennzeichneten hydrologischen Verhältnissen des pleistozänen Tieflands. Die vorliegenden pfadbezogenen Konzepte mit sehr unterschiedlicher Flächendifferenzierung unterscheiden zwischen Stofftransport auf der Landoberfläche (Oberflächenabfluss, Bodenabtrag) und im Boden/Grundwasserleiter. Problematisch gestalten sich Übertragung und Parametrisierung dieser Prozesse auf der Mesoskala (Einzugsgebiete). Weniger gut beschreibbar sind ebenso die Prozesse des Bodenabtrags, zu deren Quantifizierung auch verbesserte prozessorientierte Modelle benötigt werden, und die komplexen geo- und biogeochemischen Stofftransformationsprozesse in der nicht durchwurzelten ungesättigten und gesättigten Zone. Stofffrachten, die sich bereits auf dem unterirdischen Pfad befinden, erfahren noch vor ihrem Übertritt in die Gewässer eine Reduktion in den oft vermoorten Gewässerrandbereichen. Auch der oberirdische Stofftransfer aus dem Einzugsgebiet in das Gewässer kann in solchen, aquatische und terrestrische Ökosysteme verbindenden Landschaftselementen vermindert werden. Kenntnisse zur Quantifizierung, Bewertung und Steuerung des Stoffumsatz- und -retentionsvermögens kleinerer Fließgewässersysteme der Ober- und Mittelläufe sowie feuchter Senkenareale in Binneneinzugsgebieten werden benötigt, um Handlungsoptionen zum Gewässerschutz ableiten zu können und tatsächlich in Unterliegergewässer und -gebiete gelangende Stofffrachten abzuschätzen. Dabei zu lösende Aufgaben sind die Aufklärung der Stoffretentions- und -freisetzungsprozesse, insbesondere für die gewässergüterelevanten Stoffe N, P, C und O, die Quantifizierung von Retentionspotenzialen für geohydro- und gewässermorphologische Typen, die Ableitung von Leitprozessen und -parametern sowie Bioindikatoren und die Erarbeitung von Algorithmen zur Quantifizierung der Potenziale auf mesoskaliger Ebene. Projektziel: Entwicklung verbesserter skalen- und pfadbezogener Methoden und Modelle zur Quantifizierung der Transport- und Transformationsprozesse wassergelöster Stoffe sowie deren Wechselwirkungen in den Kompartimenten von Einzugsgebieten des pleistozänen Tieflands als Grundlage für die Beschreibung und Bewertung der Stoffretentionspotenziale sowie der Wirkung von Landnutzungsänderungen auf die Stoffbelastung kleiner Stand- und Fließgewässer.
The main objective of the project is to investigate, assess and enhance the potentiality of promising technological options (i.e., technologies, processes and concepts) for the treatment of industrial wastewater with the specific aim to provide tailor-mad e solutions to end-users for a wide range of wastewaters. Such solutions will be essentially based on the optimised integration of the investigated options and on technological improvements with respect to treatment system components, operation and control. Referring to the investigated options and the envisaged technological solutions, the project's goals are: -Investigating and enhancing the performances of promising wastewater treatment options such as aerobic granulation, integrated advanced oxidation processes (AOP) and membrane-based hybrid processes -Achieving fundamental and technological knowledge advancements necessary for advanced wastewater treatment application in different industrial sectors -Assessing the economic and environmental sustainability of promising wastewater treatment options -Developing integrated tailor-made solutions for end-users in different industrial sectors -Transferring the developed know-how to potential end-users inside and outside the project -Favouring their actual implementation for enhancing the EU Water Industry competitiveness. In order to achieve such goals, coordinated research activities will be carried out on selected options treating different wastewater. The experiences from such activities will be merged to define tailor-made solutions for end-users in different industrial sectors. A major goal will be the definition of treatment needs and framework conditions for a wide range of wastewaters based on the specific features of the options investigate d (i.e., aerobic granulation, AOP combined processes, membrane contactors, membrane chemical reactors).

The project examines funding of environmental technology development and commercialisation. The objectives are to: measure the performance of existing funding schemes (emphasising commercial-type funding); determine how environmental aspects are dealt with; identify obstacles; and suggest evolution of new schemes. Eight project work packages address these objectives, and also include development of environmental technology typologies, analysis of funding gaps, and comparison to Japan and the USA. The project supports SSP 5A by connecting policy and practice, linking researchers from across the EU, and using wide consultation to disseminate knowledge and maximise exploitation of research results. Consortium partners are drawn from five EU states, and have expertise and networks in private and public environmental technology funding and technology development processes. Stakeholder consultation with private and public funders, developers, academics, policy makers and NGOs will support research and knowledge dissemination. Consultation will include major public conferences and forums, sector-specific focus groups, and workshops to test analysis and geographic variations. Consultation and publication and dissemination of the final report will spur innovation by private and public funders, supporting knowledge exploitation after project completion. Research will emphasise private sector solutions, but will also include public-private partnerships, which are innovative measures that can assist in closing the funding gap. The varying applicability of such partnerships across different EU states will also be considered. The two project deliverables will be a database containing research and contact information, and a widely published final report that will integrate all research and recommendations.

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 Xenobiotikum 4-Nitrophenol kann als Industriechemikalie (Ausgangsverbindung für zahlreiche Substanzen) oder als Metabolit von Pflanzenschutzmitteln (z.B. des Insektizids Parathion) in die Umwelt gelangen. Auf Grund seiner physikochemischen Eigenschaften wird es von Pflanzen aufgenommen. Ziel des Vorhabens war es, das Schicksal der Verbindung in Pflanzengeweben zu studieren. Als Modellsysteme dienten dabei neben ganzen Pflanzen (aseptisch auf Hydrokultur gezogen) insbesondere Zellkulturen (Kallus oder Suspension), wobei die untersuchten Pflanzenspezies Sojabohne (Glycine max), Weizen (Triticum aestivum), Karotte (Daucus carota), Kornrade (Agrostemma githago), Windhafer (Avena fatua) und Stechapfel (Datura stramonium) waren. Neben Zuckerkonjugaten (Mono- und Disaccharide, Malonylglucoside) interessierten vor allem sogenannte nicht-extrahierbare Rückstände von 4-Nitrophenol. Bei letzteren stellt man sich kovalente und nicht-kovalente Bindungen zwischen Xenobiotika und unlöslichen pflanzlichen Makromolekülen, wie z.B. Lignin, Cellulose, Hemicellulose und Pektin, vor. Ein weiteres Ziel des Vorhabens war es zu untersuchen, ob Pflanzen als Senke zu Eliminierung von 4-Nitrophenol in der Umwelt fungieren können.
Objective: IPCC climate change scenarios have a global perspective and need to be scaled down to the local level, where decision makers have to balance risks and investment costs. Very high investments might be a waste of money and too little investment could result in unacceptable risk for the local community. PREPARED is industry driven, 12 city utilities are involved in the project and the RDT carried out is based on the impacts of climate change the water supply and sanitation industry has identified as a challenge for the years to come. The result of PREPARED will be an infrastructure for waste water, drinking water and storm water management that will not only be able better cope with new scenarios on climate change but that is also managed in a optimal way. We will have complexes monitoring and sensor systems, better integration and handling of complex data, better exploitation of existing infrastructures through improved real time control, new design concepts and guidelines for more flexible and more robust infrastructures. PREPARED will involve the local community in problem identification and in jointly finding acceptable system solutions, that are supported by all, through active learning processes. Activities and solutions in PREPARED will be based on a risk assessment and risk management approach for the whole urban water cycle, through the development of innovative Water Cycle Safety Plans. Other innovations are sensors and models that will enable faster and better actions on changes and new design rules for more resilient design. We will combine European knowledge with valuable knowledge from Australia and the USA, to make the European Water sector more competitive. This to enable our industrial partners to export the products developed in PREPARED to other regions of the world, thus contributing to the Lisbon Goals but also to the MDGs. To ensure this exploitation the PREPARED consortium consist of more than 50% industrial partners and is demand driven.
