Pastoral livestock farming in the Eastern Malian Sahel (Hombori): Survey on flows in two livestock markets

Pastoral livestock farming is a major activity in the Sahel. In the eastern Malian Sahel, in addition to its contribution to the household economy, this type of livestock farming plays an important role in enhancing the value of an environment that is not very conducive to rain-fed crops because of its low rainfall. This study was conducted in the district of Hombori to assess marketed livestock production through the...
