Pastoralism has now emerged as the main way of using natural resources sustainably in arid zones. However, it faces numerous obstacles linked to climatic variations, growing competition for access to resources, and the economic issues relating to production.
In relation to the desertification process in particular, farmers and politicians lack biophysical and socioeconomic information on the dynamics and viability of such production systems: mobility of people and animals, specific pastoral vulnerability criteria such as diversification of activities, social integration, water availability for cattle, market prices, etc. CIRAD, as part of its work within the International Research Unit on Pastoralism and with partners in the Sahel, is currently developing a system to fill in those gaps.
The first SIPSA model (information system for pastoralism in the Sahel) has been tested in Senegal. Unlike the systems that existed previously, it includes all the players involved, rather than a single institution. Moreover, the information it relays, such as the state of the water resource and market prices, can be used on a local and also an international scale. It is disseminated by means tailored to the users - written, maps, radio, farmer networks, etc - and at very low cost. The system also makes it possible, depending on user requirements, to disseminate information selectively. For instance, this could mean informing animal farmers of pasture availability, but only in the event of a bad year.
In 2006, the model is being adapted to other partner countries, thanks to national networks of concerned players, coordinated by Aghrymet. The tool, coupled with other information systems (cereals, food security), should help pastoral development players manage crises more efficiently in the short term, fight deseretification and contribute to sustainable development of pastoralism in the Sahel. The programme is due to run until 2009-2010.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
