The greening of Sub-Saharan Africa

18.09.2008
The green revolution that has led to food being far more abundant now than forty years ago in South America and Asia has all-but bypasses Sub-Saharan Africa as that region's population trebled over that time period.

Now, writing in the International Journal of Technology and Globalisation researchers in The Netherlands point to possible causes for this disparity and offer hope of reversing the trend based on a technological approach.

Agricultural production expert Prem Bindraban, plant breeder Huub Loeffler, and ecologist Rudy Rabbinge of Wageningen University and Research Centre in The Netherlands, highlight the disparity between growing food availability across the globe compared with Sub-Saharan Africa (SSA). Food has increased by almost one third per person over the last forty years but has decreased by 12% in SSA.

Currently 90% of the SSA population lives in rural areas and 70% of the labour force works in the agricultural sector. This figure is higher for some countries, including Burundi. As such, agriculture is an important economic sector that generates 30-60% of Gross Domestic Product. Nevertheless, the population has increased from 200 million in 1960 to 600 million today and finds 180 million people malnourished in SSA.

With most poor people living in rural regions and employed in agriculture, they explain that there is new interest in how farming and food production might drive overall development. Bindraban and colleagues emphasise how agricultural development has served as a "stepping stone for overall economic development in developed nations and in newly developing economies in Asia".

While there have been a few isolated successes in development, modern agricultural technology, including genetically modified crops, modern pesticides, fertilisers and irrigation methods, mono-cropping for bulk production, has not spread widely to benefit the entire continent. "For agriculture to develop, proper market and institutional conditions should catalyse the process that is initiated by technologies, as has been found for the green revolution," the researchers explain.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
