The Clean Development Mechanism (CDM) suffers from a price level for certificates that went down to almost zero in a period less than a year. Additionally, no short-term price recovery is expected which could incentivise new projects. A risk is that market participants leave the market and the valuable CDM knowledge base on GHG mitigation and quantification will be lost. The CDM Market Support Study analyses the actual price vulnerability of projects and identifies various financing and project type opportunities for project developers and for (institutional public) investors who intent to support the CDM project continuation and the further development of the CDM framework. The study also shows how the current regulatory framework of the CDM can be maintained by transferring it to future mechanisms. This could be a chance to develop the CDM from a pure market-based instrument towards an integrated part within future market-based and also policy-based instruments. The CDM can provide useful components to currently discussed or tested instruments such as the NMM (New Market Mechanism), the FVA (Framework for Varios Approaches), NAMAs (Nationally Appropriate Mitigation Actions) or results-based financing approaches. The study was financed by the German KfW-managed PoA Support Centre . The aim of the PoA-Support-Centre Germany is to support the development of Programmes of Activities (PoAs) under CDM and JI (Joint Implementation) worldwide.
Egypt passed a revolution and changed its political system, but many problems are still lacking a solution. Especially in the field of water the North African country has to face many challenges. Most urgent are strategies to manage the limited water resources. About 80% of the available water resources are consumed for agriculture and the rest are for domestic and industrial activities. The management of these resources is inefficient and a huge amount of fresh water is discarded. The shortage of water supply will definitely influence the economic and cultural development of Egypt. In 2010, Egypt was ranked number 8 out of 165 nations reviewed in the so-called Water Security Risk Index published by Maplecroft. The ranking of each country in the index depends mainly on four key factors, i.e. access to improved drinking water and sanitation, the availability of renewable water and the reliance on external supplies, the relationship between available water and supply demands, and the water dependency of each countrys economy. Based on this study, the situation of water in Egypt was identified as extremely risky. A number of programs and developed strategies aiming to efficiently manage the usage of water resources have been carried out in the last few years by the Egyptian Government. But all these activities, however, require the availability of trained and well-educated individuals in water technology fields. Unfortunately, the number of water science graduates are decreasing and also there are few teaching and training courses for water science offered in Egypt. However, there is still a demand for several well-structured and international programs to fill the gap and provide the Egyptian fresh graduates with the adequate and up-to-date theoretical and practical knowledge available for water technology. IWaTec is designed to fill parts of this gap.
Ozone vertical column density in Dobson Units as derived from Sentinel-5P/TROPOMI observations. The stratospheric ozone layer protects the biosphere from harmful solar ultraviolet radiation. Ozone in troposphere can pose risks to the health of humans, animals, and vegetation. The TROPOMI instrument aboard the SENTINEL-5P space craft is a nadir-viewing, imaging spectrometer covering wavelength bands between the ultraviolet and the shortwave infra-red. TROPOMI's purpose is to measure atmospheric properties and constituents. It is contributing to monitoring air quality and providing critical information to services and decision makers. The instrument uses passive remote sensing techniques by measuring the Top Of Atmosphere (TOA) solar radiation reflected by and radiated from the earth and its atmosphere. The four spectrometers of TROPOMI cover the ultraviolet (UV), visible (VIS), Near Infra-Red (NIR) and Short Wavelength Infra-Red (SWIR) domains of the electromagnetic spectrum, allowing operational retrieval of the following trace gas constituents: Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Formaldehyde (HCHO), Carbon Monoxide (CO) and Methane (CH4). Daily observations are binned onto a regular latitude-longitude grid. Within the INPULS project, innovative algorithms and processors for the generation of Level 3 and Level 4 products, improved data discovery and access technologies as well as server-side analytics for the users are developed.

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.
Täglich sammeln wir Staub - wenn wir uns in einem Raum aufhalten, wenn wir durch eine Wiese oder über eine Straße gehen oder auch in einem Buch lesen - und täglich versuchen wir, ihn wieder loszuwerden. Unser Drang nach Reinheit hat eine ganze Industrie entstehen lassen, die von Staubsaugern bis zu High-Tech-Filtern alle Arten von kleinen und größeren Hilfsmitteln anbietet. Für die Wissenschaft ist Staub kein Dreck. Was für den Alltagsmenschen ein Symbol der Zerstörung ist, birgt für den Forscher viele wichtige Informationen. Denn aus einer Analyse des Staubes lässt sich vieles über unsere gegenwärtige und sogar über vergangene Umwelten lernen. Zum anderen erobert die Wissenschaft mit Mikro- und Nanotechnologien die Welt des Winzigen. Denn das sehr Kleine eröffnet besondere technische Chancen. Auch diese aktuellen Entwicklungen und die damit verbundenen Chancen und Risiken soll die Ausstellung aufzeigen. Die Ausstellung wurde von November 2004 bis Oktober 2005 im Wissenschaftszentrum Umwelt der Universität Augsburg gezeigt werden. Sie umfasst 30-40 Exponate, darunter mehrere Hands-on-Exponate. Leihgeber für spezielle Objekte sind das Bundeskriminalamt, das Landesamt für Umweltschutz in Bayern, das Umweltbundesamt, der Deutsche Wetterdienst und weitere Institutionen. Ein ausstellungsbegleitendes Buch wird beim Oekom Verlag in München erscheinen. Im Anschluss an die Augsburger Station ging die Ausstellung auf Wanderschaft und wurde inzwischen an sechs weiteren Stationen gezeigt. Die Zahl der Besucher liegt bereits weit über 100.000.
The proposed project is a research cooperation between the TU Dresden’s chair of Urban Water Management and the chair of Hydrobiology. The project aims to detect and quantify the contribution of a city’s sewer system on the spread, dynamics and seasonality of antibiotics and antibiotic resistance genes within an urbanized water body. Antibiotic resistance represents a high risk to human health as well as the public health system, due to their presence in, or acquisition by, pathogenic and/or opportunistic bacteria occurring in the environment. One among other emission sources of resistant strains into the environment is the sewer network, which should be exemplary investigated at our study site, the Lockwitzbach catchment within the city of Dresden. Six monitoring stations are already in operation there, equipped with online sensors for water quantity. Four out of six are recording water quality, including auto samplers. Two of the stations are dedicated to river monitoring, four further stations were mounted within the sewer system at rain water outlets and at a combined sewer overflow (CSO) structures, draining into Lockwitzbach. This monitoring network will be used and enhanced for the detection and sampling of specific contributions from the urban drainage network on the presence and dispersion of antibiotic resistances. Event-based and seasonal sampling campaigns coupled with analysis on chemical and microbiological parameters should be performed on water and biofilm samples to detect contribution patterns from the sewer outlets together with seasonal trends in composition and presence of antibiotic resistance in the bacterial community. Furthermore, emission pathways and the remaining of heavy metals from the sewer network, that also select for antibiotic co-resistancence, will be under examination. A particle transport model for the sewer catchment will be coupled with a hydraulic model for stream and sewer network and calibrated to predict gained water quality parameters as well as antibiotic resistant gene discharge patterns. Different treatment methods will be implemented in the model and evaluated. These results will yield valuable information on possible emission scenarios and pathways, as well as their importance on the spread of antibiotic resistance in the aquatic environment.
So far, there is little knowledge on the fate of nanoparticles and nanoparticle-associated pollutants in soils. From the state of the art we presume nanoparticle aging in soils to change their surface characteristics, their sorption capacity and mobility. However, the processes controlling nanoparticles aging in soils are hardly investigated. We hypothesize that engineered inorganic nanoparticles (EINP) in soil undergo pedogenic processes such as chemical weathering, accumulation of organic matter and aggregation and that these processes govern both, the mobility of EINP and their sorption capacity for contaminants. Thereby we will mainly address the two key hypothesis of INTERNANO that (i) nanoparticle aging involves reversible and irreversible changes and (ii) that nanoparticle mobility and their interactions with pollutants are determined by environmental conditions rather than by original surface characteristics. We will expose nanoparticle to soils and soil suspensions under various, defined conditions. At the end of the respective incubation time we will study the change in surface properties, aggregation state and contaminant sorption onto nanoparticles, using methods, which are suitable for nano-scale analyses (light scattering, HR TEM, XANES). Size effects on aging will be analysed exemplarily for TiO2 EINPs. The derived process knowledge will help to evaluate the environmental significance of nanoparticles in soils and serve as a basis to predict risks associated with nanoparticle leaching from soils.
Im Zusammenhang mit Versuchen zur Wiederverwertung von an Schlachthoefen anfallenden Schweinemageninhalt, soll das parasitologische Risiko ermittelt werden, das bei einem Recycling fuer die Umwelt entsteht. Stichproben werden durch Sedimentation-Flotations-Verfahren und Kultivierung auf Geschlechtsprodukte und Ueberlebensstadien von Helminthen und Protozoen untersucht. Bisher wurden in 300 untersuchten Proben bei etwa 10 Prozent Eier von Magendarmstrongyliden und bei 4 Prozent Eier von Askariden, sowie bei 1 Prozent weitere Helmintheneier und bei 4 Prozent Eier von als 1 Prozent Protozoenzysten nachgewiesen. Es ist geplant, die Ueberlebens-, Entwicklungs- und Ansteckungsfaehigkeit der im Schweinemageninhalt gefundenen Stadien zu untersuchen, um eine Aussage ueber ein Ansteckungsrisiko bei Weiterverfuetterung machen zu koennen.
