Due to the low level of soil fertility and the limited availability of water, the food situation in Africa is more serious than on any other continent. However, the people meet these challenges with an inventive spirit and much improvisation, in order to utilise all available resources.
Neglected for decades in terms of politics and science, the intensive cultivation of urban areas and the areas surrounding them makes an important contribution with regard to the income and food security of poor population groups, whilst at the same time carrying health and environmental risks. The goal of the “UrbanFoodPlus” project, which is coordinated by the University of Kassel and the Ruhr University, Bochum, is to understand, to boost, and to optimise the various forms of urban farming.Agricultural scientists and soil specialists, working together with economists, wastewater engineers, ethnologists from Göttingen and geographers from Freiburg, develop interdisciplinary approaches to unlocking the full potential of the growing of staple foods and vegetables, and of animal husbandry, in farming niches of urban areas and the surrounding areas. The Federal Ministry of Education and Research (BMBF) will supply 4.3 million Euros over the next three years. This is a portion of the total of 7.5 million Euros that will be made available over a period of five years.
Initial field research takes place in Ouagadougou/Burkina Faso and Tamale/Ghana, and will then be extended to other West African cities. The trials will include small-scale crop-growing experiments, questioning of growers, sellers and administration representatives. There will also be extensive training measures on simple technological innovations, including the use of charcoal both as a water filter and an organic fertilizer.The scheme is divided into several project groups. A working group led by Bürkert is examining biodiversity, food efficiency, flow of materials and certification measures in vegetable production. Prof. Schlecht (University of Kassel and Georg August University, Göttingen), leads a project group that is analysing the efficiency of animal husbandry systems; this includes both the use of stock-feeds, and the utilisation of accumulating dung. Other project groups led by Prof. Marschner and Prof. Wichern (both from the Ruhr University, Bochum) determine the influence of natural fertilizers and household waste water on soil quality and product hygiene, aspects of food security, socio-political frame conditions (Prof. Schareika, University of Göttingen) and possible politico-economical profits derived from the suggested improvements (Prof. Löwenstein, University of Bochum). “Hereby, we want to take sociological and politico-economical consequences into account”, says Bürkert: “How do these urban economic cycles lower the risk of poverty? What part do the women play and how does their task in raising food security influence their role in society? What significance does this type of farming have, especially for ethnic minorities in society?” Prof. Drescher of the University of Freiburg concerns himself with this matter in particular.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
