Since 1987, CIRAD has been working with the Nigerian administration (in the form of several successive partnerships*), on development-oriented research projects concerning the development of natural forests and the supply of dendroenergy to towns.
Today, more than 600 000 hectares of developed forest are managed sustainably. Over 300 local rural market structures for dendroenergy and syndicates for dum leaf and gum Arabic have been created. The annual revenue generated locally by the commercial production from these markets alone is estimated at nearly 500 million CFA francs. On a technical level, sylvicultural guidelines for the main types of forest formation have now been defined and pastoral management has become an integral part of new development plans.
The supply of dendroenergy, which is vital for town populations, can be insured if forestry resources are managed sustainably. Moreover, the rural populations manage their woody resources, redistributing revenue to the local populations, villages and authorities. In fact, the authorities recognise the local communities as the legitimate interlocutors within a legislative framework which includes a fiscal incentive.
The system for sustainable management still needs to be extended in order to secure the long-term supply of dendroenergy. The administrative forestry control system is lacking and the decentralisation and devolution process should be completed. The institutional framework was modified with a new forestry law. This means that, today, the effective transfer of forestry management skills has been formalised to benefit the territorial bodies and local communities.
In the near future, the establishment of bodies devolved from the rural code (regional and communal forestry commissions), will mean that communities and authorities have access to a valuable tool for controlling and conserving sylvopastoral areas in the form of a land development scheme.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
