Spurenelementkreisläufe und Flüsse im südlichen Indischen Ozean - ein Beitrag zu GEOTRACES

Der südliche Indische Ozean gehört zu den am wenigsten untersuchten Meeresgebieten. Entlang eines zonalen Transekts bei 23°S im südlichen Indischen Ozean wollen wir mit Hilfe der Verteilung von isotopischen Tracern (Radiumisotope, Thorium, Helium) die Quellen, die Senken und die Flüsse von Spurenelementen (TEs: Cd, Co, Cu, Fe, Mn, Mo, Ni, V, Zn) in der Wassersäule untersuchen. Die Anwendung von Radiumisotopen (224Ra, 223Ra, 228Ra,226Ra,), Thoriumisotopen (234Th, 232Th) und Heliumisotopen (3He, 4He) erlaubt ein besseres Verständnis der biogeochemischen Zyklen von TEs. Da einige dieser Spurenelemente als Mikronährstoffe fungieren, wollen wir ihre biogeochemischen Kreisläufe und ihre Wechselwirkungen mit der Bioproduktivität im Oberflächenwasser sowie ihre Wechselwirkungen mit den Kohlenstoff- und Nährstoffkreisläufen erforschen. Durch die Kombination von Messungen von TEs mit Radium- und 234Th-Isotopen als Tracer für vertikale und horizontale Flüsse, 232Th als Tracer für den Staubeintrag und Heliumisotope als Tracer für einen hydrothermalen Eintrag, werden wir die Zufuhrpfade von TEs aus der Atmosphäre, den Kontinenten (hauptsächlich dem Sambesi-Fluss), den Sedimenten der afrikanischen und australischen Kontinentalschelfe und aus den hydrothermalen Quellen (Hydrothermalismus am Mittelindischen Ozeanrücken) bestimmen und quantifizieren. Diese Untersuchungen sollen auf Probenmaterial basieren, das während der Sonne Ausfahrt SO-276 (Juli – August 2020) von Durban (Südafrika) nach Fremantle (Australien) gewonnen wird. Unsere Untersuchungen sind Teil des international koordinierten Programms GEOTRACES und werden zum „Second Indian Ocean Expedition Program (IIOE-2)“ beitragen. Wir erwarten, dass die Ergebnisse der vorgesehenen Untersuchungen einen signifikanten Beitrag zum Verständnis von Ökosystemen und ihrem chemischen Milieu liefern werden.

YEEES - Yields of Evocative Entrepreneurial approaches on Environment and Society

Entrepreneurial solutions as well as ICT play a critical role in achieving sustainability. We thus develop an inter- and transdisciplinary project that focusses on Yields of Evocative Entrepreneurial approaches on Environment and Society (YEEES). We especially elaborate on the resilience of cities and peri-urban areas, while focusing challenges in the fields of urban agriculture and mobility. Our project connects the universities of Lüneburg and Oldenburg with the universities in South Africa (NMMU), Namibia (UNAM) and Mosambique (UPM) via implementing two interconnected centers seen as international networks where the above mentioned topics will be addressed in Research and Teaching: The YEEES Research Center and the YEEES Training Center. The YEEES Research Center aims at being a long-term, visible and renowned network of German and African researchers from a variety of disciplines. Four research groups, focusing on 'Innovation', 'Imovation', 'ICT' and 'Education' are connected via a common goal: Delivering excellent and relevant research results that contribute to the global challenge of ensuring sustainability by focusing on innovative and imovative sustainable entrepreneurial approaches using ICT. The YEEES Training Center consists of four units: The Lecturing Hub, the Postgraduate Trainings, the Continuing Training, and the Scholarships. As an international, trans- and interdisciplinary network of relevant lecturers, researchers, practitioners and students, the center aims at becoming an internationally renowned center that connects Germany and Africa by developing and implementing innovative teaching based on state of the art research in the fields of Entrepreneurship, Sustainability and ICT. The YEEES project will foster the development of innovative entrepreneurial approaches, as e.g. the founding of sustainability start-ups and organisations in the respective fields. Our work further more supports the development of skills and mindsets that lead to entrepreneurial behavior in a way that future change agents identify and exploit opportunities for creative and innovative or 'imovative' solutions. We also contribute to a broad and strong German-African cooperation in various ways. That allows mind changing experiences, which on short and long term perspective enable people to contribute to sustainable change.

Improving the Livelihood of the Rural Population through the Production of Bushmeat in Ghana

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.
