In this chapter, it is argued that the application of scientific knowledge is an essential prerequisite for sustainable resource management. Scientific inputs have the following components when applied to a specific region: (1) a through analysis of the resource base, with emphasis on feed and wa...

An analysis of feed demand and supply for pastoral livestock: the Gourma region of Mali
Published and new data from experiments conducted in several range sites in Niger and Mali were analysed to assess wet season, dry season and year-round animal weight changes, stocking rates, forage availability, feed intake and faecal excretions of cattle, sheep and goats. Herbage availability o...
