Trypanotolerant livestock in West and Central Africa. Volume 3. A decade's results
This volume presents major results obtained since the publication of volume 1 and 2 and updates national data on trypanotolerant cattle. The first part analyses populations and their trends between the two surveys and reviews research activities and development activities. It also gives recent information available on the potential and utilisation of trypanotolerant livestock. Part two presents recent data for the 18 study countries, as well as for Equatorial Guinea which was not covered in volume 2.
Transhumance cattle production system in North Gondar, Amhara region, Ethiopia: is it sustainable?
The study was carried out in three highland woredas (districts) of Chilga, Dembia and Gondar Zuria in north Gondar Zone, Amhara Region, Ethiopia. These woredas were purposively selected because of their long experience in transhumance cattle production system. The objectives of the study were to characterize the transhumance cattle production system, identify the major constraints and forward appropriate developmental interventions for the future. Informal and formal surveys were employed to collect qualitative and quantitative data.

Transhumance in the Tigray highlands (Ethiopia)
Transhumance, the seasonal movement of herds occurring between two points and following precise routes repeated each year, is practiced on a broad scale in the open field areas of Tigray (North Ethiopia). This article presents a characterization of the practice, factors that explain its magnitude, and recent changes. Eleven villages were selected randomly, semistructured interviews were conducted, and data on the sites were collected both in the field and from secondary sources.
