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

October-December 2021

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...

Agripreneurship development among small scale farmers In Anambra State, Nigeria

October-December 2021

The continuing decline in the price of the crude oil in the international market is a pointer to the fact that oil sector can no longer guarantee economic viability and sustainability in any nation. In Nigeria, this realization has led to increased urgency of the need to revitalize the agricultural sector, possibly return to its glorious days in the immediate post- independence. To drive the process, scholars argue for...
