One of the goals of CTA is to bring together dispersed information and knowledge in order to make it available to a larger number of users. This is particularly important when dealing with the problems caused by the drought in the Sahel. Hence a project to map grazing potential which has been entrusted to IEMVT (Institut d'Etude et de Medecine Veterinaire Tropicale in Paris) which since 1958 has mapped over 2 million square km of the Sahel (1.2 million square miles). All of the data available on any aspect of livestock raising in the zone between 150 and 800 mm isobars will be collected. The analysis will not be limited only to the botanical and hydrological aspects of grazing, but will include human disease vectors (ticks, tsetse flies), herd migrations, and livestock extension services. On the basis of resources available for grazing, one can define production potential, that is, the carrying capacity of pastures based on rainfall. Such information will be particularly useful to planners, development workers and officials responsible for environmental protection. The atlas will cover six countries: Chad, Niger, Mali, Burkina Faso, Senegal and Mauritania. It will include summaries by country as well as a regional analysis at an ecoclimatic scale for the Sahel. Scheduled for publication over three years, the first country studied has been Chad. A volume on this country has just been printed, comprising 28 maps of 80 x 65 cm. Chad was chosen as the first country to be studied because of its particularly acute documentation needs. Data collection in this field has suffered from recent political events in the country The programme will continue through 1986 with Niger and Burkina Faso.
