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 Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
