There is evidence to show that there has been a transition regarding the structure of land ownership in Africa, particularly a rise in the number of commercialised medium-scale farms (MSFs) in sub-Saharan Africa (SSA). The objective of this study was to determine whether the growth of MSFs promotes agricultural commercialisation in SSA, and the brief presents the preliminary results of the first round of data analysis collected through the survey. Emphasis is placed on the characteristics of these emergent MSFs, the nature of the structural changes that produce them, and how they potentially influence the welfare of small-scale farms in Nigeria. The results of the brief are divided into the current topics: Pathways into MSF commercialisation, land access and use, farm production and assets, interaction between MSFs and SSFs, and agricultural commercialisation.
