Das Projekt "Improving the Livelihood of the Rural Population through the Production of Bushmeat in Ghana" wird vom Umweltbundesamt gefördert und von Universität Hamburg, Arbeitsbereich für Weltforstwirtschaft und Institut für Weltforstwirtschaft des Friedrich-Löffler-Institut, Bundesforschungsinstitut für Tiergesundheit durchgeführt. 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.
Das Projekt "Development of a modelling system for prediction and regulation of livestock waste pollution in the humid tropics" wird vom Umweltbundesamt gefördert und von Universität Hohenheim, Institut für Tropische Agrarwissenschaften (Hans-Ruthenberg-Institut), Fachgebiet Pflanzenbau in den Tropen und Subtropen (490e) durchgeführt. Introduction: In Malaysia, excessive nutrients from livestock waste management systems are currently released to the environment. Particularly, large amounts of manure from intensive pig production areas are being excreted daily and are not being fully utilised. Alternatively, the excess manure can be applied as an organic fertiliser source in neighbouring cropping systems on the small landholdings of the pig farms to improve soil fertility so that its nutrients will be available for crop uptake instead of being discharged into water streams. Thus, there is a need for better tools to analyse the present situation, to evaluate and monitor alternative livestock production systems and manure management scenarios, and to support farmers in the proper management of manure and fertiliser application. Such tools are essential to quantify, and assess nutrient fluxes, manure quality and content, manure storage and application rate to the land as well as its environmental effects. Several computer models of animal waste management systems to assist producers and authorities are now available. However, it is felt that more development is needed to adopt such models to the humid tropics and conditions of Malaysia and other developing countries in the region. Objectives: The aim is to develop a novel model to evaluate nutrient emission scenarios and the impact of livestock waste at the landscape or regional level in humid tropics. The study will link and improve existing models to evaluate emission of N to the atmosphere, and leaching of nutrients to groundwater and surface water. The simulation outputs of the models will be integrated with a GIS spatial analysis to model the distribution of nutrient emission, leaching and appropriate manure application on neighbouring crop lands and as an information and decision support tool for the relevant users.
Das Projekt "Rehabilitation of Degraded Forests in Yunnan (German-Chinese Cooperation for Agrarian Research)" wird vom Umweltbundesamt gefördert und von Universität Hamburg, Arbeitsbereich für Weltforstwirtschaft und Institut für Weltforstwirtschaft des Friedrich-Löffler-Institut, Bundesforschungsinstitut für Tiergesundheit durchgeführt. 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.
Das Projekt "Profiling methane emission in the Baltic Sea: Cryptophane as in-situ chemical sensor" wird vom Umweltbundesamt gefördert und von Leibniz-Institut für Ostseeforschung Warnemünde (IOW), Sektion Meereschemie durchgeführt. To overcome the limitation in spatial and temporal resolution of methane oceanic measurements, sensors are needed that can autonomously detect CH4-concentrations over longer periods of time. The proposed project is aimed at:- Designing molecular receptors for methane recognition (cryptophane-A and -111) and synthesizing new compounds allowing their introduction in polymeric structure (Task 1; LC, France); - Adapting, calibrating and validating the 2 available optical technologies, one of which serves as the reference sensor, for the in-situ detection and measurements of CH4 in the marine environments (Task 2 and 3; GET, LAAS-OSE, IOW) Boulart et al. (2008) showed that a polymeric filmchanges its bulk refractive index when methane docks on to cryptophane-A supra-molecules that are mixed in to the polymeric film. It is the occurrence of methane in solution, which changes either the refractive index measured with high resolution Surface Plasmon Resonance (SPR; Chinowsky et al., 2003; Boulart et al, 2012b) or the transmitted power measured with differential fiber-optic refractometer (Boulart et al., 2012a; Aouba et al., 2012).- Using the developed sensors for the study of the CH4 cycle in relevant oceanic environment (the GODESS station in the Baltic Sea, Task 4 and 5; IOW, GET); GODESS registers a number of parameters with high temporal and vertical resolution by conducting up to 200 vertical profiles over 3 months deployment with a profiling platform hosting the sensor suite. - Quantifying methane fluxes to the atmosphere (Task 6); clearly, the current project, which aims at developing in-situ aqueous gas sensors, provides the technological tool to achieve the implementation of ocean observatories for CH4. The aim is to bring the fiber-optic methane sensor on the TRL (Technology Readiness Level) from their current Level 3 (Analytical and laboratory studies to validate analytical predictions) - to the Levels 5 and 6 (Component and/or basic sub-system technology validation in relevant sensing environments) and compare it to the SPR methane sensor, taken as the reference sensor (current TRL 5). This would lead to potential patent applications before further tests and commercialization. This will be achieved by the ensemble competences and contributions from the proposed consortium in this project.
Das Projekt "Evaluating current European agri-environment schemes to quantify and improve nature conservation efforts in agricultural landscapes (EASY)" wird vom Umweltbundesamt gefördert und von Eidgenössische Forschungsanstalt für Wald, Schnee und Landschaft durchgeführt. Research question: Agri-environment schemes play an increasingly important role in European CAP (Common Agricultural Policy) to support biodiversity and environment in agricultural landscapes. They have been implemented since 1992 and now cost a yearly 1.7 billion Euro. Still, there is no conclusive evidence that these schemes actually do contribute to the conservation of particularly biodiversity. The primary objective of this project is to evaluate the (cost-) effectiveness of European agri-environment schemes in protecting biodiversity and to determine the primary processes that determine their effectiveness. This project furthermore aims to determine how CAP may be introduced in candidate EU-members without unacceptable loss of biodiversity. It will provide simple guidelines how researchers, governmental authorities may efficiently evaluate agri-environmental measures. Aim: Agri-environment schemes have been used to protect biodiversity and environment in agricultural areas since 1992. Their effectiveness has never been reliably evaluated. This project aims to evaluate the (cost-)effectiveness of agri-environment schemes with respect to biodiversity conservation in five European countries. It will determine the proper scales that have to be addressed for conservation efforts for a range of species groups. It will determine the most important environmental factors that influence the effectiveness of the schemes. Based on this, recommendations will be made how the effectiveness of schemes may be improved and simple guidelines will be produced how ecological effects of agri-environment schemes can be evaluated efficiently by governmental authorities or other institutions. The ecological effects of the introduction of CAP in a candidate EU-member will be investigated to reduce negative side effects of anticipated land-use changes Scientific methods: We will examine the effectiveness of agri-environment schemes by surveying pairs of fields: a field with an agri-environment scheme and a nearby field that is conventionally managed. In five countries, in each country in three areas, and in each area on seven pairs of fields the species richness of birds, plants and three insect groups (pollinators, herbivores, predators) will be determined. Effects of schemes on pollination efficiency and pest control will be examined using indicator communities. Correlative studies will examine the effects of landscape structure, land-use intensity and species pool on the effectiveness of agri-environmental measures. The spatial scale that is relevant to nature conservation efforts will be investigated via the spatial distribution of species groups. The results will be used to formulate recommendations how to improve the effectiveness of agri-environment schemes and to construct a set of simple guidelines how schemes can be evaluated efficiently yet reliably.
Das Projekt "Zur Verfassungsmäßigkeit des Brennstoffemissionshandelsgesetzes (BEHG): Rechtsgutachten" wird vom Umweltbundesamt gefördert und von lindenpartners Partnerschaft von Rechtsanwältinnen und Rechtsanwälten mit beschränkter Berufshaftung Birkholz Varadinek Asmus durchgeführt. Das Rechtsgutachten untersucht die Verfassungsmäßigkeit des Brennstoffemissionshandels-gesetzes (BEHG) und dessen Vereinbarkeit mit dem Unionsrecht. Zur Ermittlung des verfassungsrechtlichen Maßstabs muss zunächst bestimmt werden, ob es sich bei den Entgelten, die für den Erwerb der Emissionszertifikate zu zahlen sind und dem Bund zufließen, um Steuern oder nicht-steuerliche Abgaben handelt. Das Gutachten kommt zu dem Ergebnis, dass es sich um nicht-steuerlichen Abgaben handelt, da die Emissionszertifikate eine staatliche Gegenleistung darstellen. Auf dieser Grundlage wird geprüft, ob die verfassungsrechtlichen Anforderungen an eine nicht-steuerliche Abgabe erfüllt sind. Es wird insbesondere untersucht, ob ein besonderer sachlicher Rechtfertigungsgrund vorliegt, der eine Verletzung des Grundsatzes der Belastungsgleichheit vermeidet. Dazu werden auf Grundlage der Rechtsprechung des BVerfG die verfassungsrechtlichen Anforderungen an einen besonderen sachlichen Rechtfertigungsgrund herausgearbeitet und analysiert, ob das BEHG â€Ì gerade in der Einführungsphase mit der Veräußerung zu einem staatlich festgelegten Preis â€Ì diesen Anforderungen genügt. Besonderes Augenmerk wird auf die Frage gelegt, ob auch bei einer Veräußerung zu Festpreisen ein staatliches Bewirtschaftungssystem i.S.d. Rechtsprechung des BVerfG angenommen werden kann. Dabei werden auch nationale und supranationale Regelungen außerhalb des BEHG berücksichtigt. Das Rechtsgutachten kommt zu dem Ergebnis, dass die Einführung der Entgelte für die Emissionszertifikate durch einen besonderen sachlichen Grund gerechtfertigt ist. Darüber hinaus untersucht das Gutachten die Vereinbarkeit der Regelungen mit dem Eigentumsschutz (Art. 14 Abs. 1 GG) und der Berufsfreiheit (Art. 12 Abs. 1 GG) sowie mit dem einschlägigen Primär- und Sekundärrecht der EU. Im Ergebnis bestehen auch insoweit keine rechtlichen Bedenken.
Das Projekt "Mögliche Ausgestaltung eines Energieeinsparverpflichtungssystems für Deutschland" wird vom Umweltbundesamt gefördert und von Fraunhofer-Institut für System- und Innovationsforschung durchgeführt. Die EU-Energieeffizienzrichtlinie (EED) sieht in Artikel 7 die Einrichtung eines Energieeinsparverpflichtungssystems (EEOS) als ein zentrales Instrument zur Erreichung von Energieeinsparzielen vor. Während mittlerweile mehr als die Hälfte der Mitgliedstaaten ein solches System eingerichtet haben, wurde eine Einführung in Deutschland zwar in verschiedenen Studien diskutiert, jedoch bisher nicht umgesetzt. Mit dieser Studie wird ein Ausgestaltungsvorschlag für ein mögliches Energieeinsparverpflichtungssystem in Deutschland unter den derzeitigen energie- und klimapolitischen Rahmenbedingungen vorgelegt. Im Rahmen eines EEOS wird durch den Staat ein Einsparziel festgelegt und auf verpflichtete Akteure allokiert. Je nach Ausgestaltung kann eine Handelskomponente (so genannte â€ÌWeiße Zertifikateâ€Ì) hinzukommen. Um ein EEOS in einem Land zu etablieren, sind Festlegungen zu zentralen Ausgestaltungsmerkmalen zu treffen. Dazu gehören neben den zu verpflichtenden Sektoren, Energieträgern und Akteuren auch die Konkretisierung des Einsparziels, Anforderungen an die durchgeführten Einsparmaßnahmen sowie Regelungen zum Handel mit Zertifikaten und zu den Nachweis- und Überprüfungsmechanismen. Die hier vorgeschlagene Ausgestaltung wurde so gewählt, dass damit eine hohe Effektivität und Kosteneffizienz des Instruments gewährleistet ist und der Markt für Energiedienstleistungen gestärkt wird. Trotz der schon stark ausdifferenzierten Förderlandschaft für Energieeffizienz könnte ein marktnahes Instrument wie ein EEOS dazu beitragen, einige der noch bestehenden Hemmnisse abzubauen, die bisher einer vollen Ausschöpfung der Energieeffizienzpotenziale entgegenstehen.
Das Projekt "Global business challenge: Breaking the oilgas water dependency with a cost-effective no-waste nanomembrane technology for water reuse (CleanOil)" wird vom Umweltbundesamt gefördert und von Likuid Nanotek SL durchgeführt. CleanOil consists on the introduction into the market of an innovative filtration solution to treat and reuse the produced water (PW), a highly polluted oily wastewater which is the largest volume byproduct associated to oil and gas production. The solution will allow achieving up to 80% reduction of water demand for oil extraction through the reuse of up to 99% of the PW, and will be based on a proprietary product - ceramic nanomembranes with an innovative production process - installed in a fully integrated solution with the equipment, instrumentation and advanced fouling monitoring and control tools and software. The project aims to achieve three objectives: (1) reducing the target membrane price up to 4 times, thanks to the upscaling of the nanomembrane production process, (2) launching worldwide highly competitive and cost-effective filtration solutions for the treatment and reuse of PW and (3) international consolidation through the new subsidiaries and strategic partners in high potential markets, aiming for a 3% share of the Likuid's target industrial filtration market, doubling the existing actual staff and achieving a tenfold increase in EBITDA profit by 2020. Likuid has identified two market segments targeted by its innovative solution: onshore, with 680 Mill.€ target market (USA, Canada, Colombia, Mexico) and offshore, with 490 Mill.€ target market (North Europe and LATAM). Potential customers for Likuid's solution are (a) the intermediary EPC, OEM and OFS companies and (b) oil producers, as end-users of the technology. In the project, onshore segment will be addressed with a Canadian demonstration for SAGD and tailing ponds and offshore segment is related to a demo study with Petrobras, who has already tested Likuid's membranes. Successfull demonstration will boost the market uptake of the new highly-efficient and cost-effective Likuid's solution, thus helping European cutting-edge technologies to position in the lead of sustainable O&G production.
Das Projekt "Economic and Ecological Restructuring of Land- and Water Use in the Region Khorezm" wird vom Umweltbundesamt gefördert und von Universität Bonn, Zentrum für Entwicklungsforschung durchgeführt. Project objectives: (1.) Concepts for landscape restructuring in Khorezm, an intensively used agricultural region in the Aral See basin. The concepts are to contribute to a more effective and at the same ecologically sustainable land and water use. (2.) Based on the concepts for sustainable management of natural resources, proposals for both legal-administrative and ecological restructuring measures are to be developed. (3.) At the same time, scientific collaboration based on a close partnership between Germany and Uzbekistan in the field of development research is to be established. Here, special attention is to be given to the training of young scientists. The basic idea of the project is to designate part of the area currently used for agriculture for ecological purposes. Possible losses in agricultural production are to be compensated for through more efficient but sustainable land and water use based on the introduction of modern and profitable agricultural production systems.
Das Projekt "Regeneration of the Robinson Crusoe's island original Forest (Juan Fernandez Archipelago, Chile)" wird vom Umweltbundesamt gefördert und von Universität Freiburg, Waldbau-Institut durchgeführt. The Juan Fernandez Archipelago National Park, and World Biosphere Reserve, is composed of three oceanic islands located 680 km west of continental Chile at 33 degree S. Its biota and in particular the flora is characterised by its diversity and high degree of endemism (63,9 percent), resulting from a long process of local evolution without anthropic influence. The Robinson Crusoe Island (RCI) is the only permanently inhabited of the archipelago, presenting human influence since 1574 (629 inhabitants). From this moment on, fires, selective cuttings and the introduction of exotic species of flora and fauna have affected enormously the forest communities. Currently 75 percent of the endemic vascular flora is considered in verge of extinction, being urgent its conservation. The original forest communities of the RCI constitute an important part of the endangered species habitat. Unfortunately there is still unclear the natural ecology of the dominant tree species. This evidence is crucial to consider in any conservation and restoration proposal. The objective of this study is to analyse where occurs the regeneration of the main tree species of the RCI original forest (Myrceugenia fernandeziana (Hook. & Arn.) Johow, Fagara mayu (Bertero ex Colla) Engl., and Drimys confertifolia Phil.). Using a forest area as case study (Plazoleta el Yunque sector) it will be assesed i) if the regeneration follows a light gradient, ii) if the species demand certain characteristics on its regeneration habitat (e.g substrate, rocks, coverage) and iii) how the main weeds (Aristotelia chilensis (Molina) Stuntz, Rubus ulmifolius Schott) affect the natural regeneration in gaps. As expected outcomes is considered the understanding of regeneration niche characters for the main tree species, and the identification of key site aspects (indicators) for the original forest self replacement. This knowledge might contribute basic information, to propose further conservation and restoration activities for this ecosystem.
