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.

Computer scientists use wave packet theory to develop realistic, detailed water wave simulations in real time. Their results will be presented at this year’s SIGGRAPH conference.
Think about the last time you were at a lake, river, or the ocean. Remember the ripples of the water, the waves crashing against the rocks, the wake following...
An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
