Abstract

While global food availability increased by 27% per person over the past four decades, it decreased by 12% in Sub-Saharan Africa (SSA). This paper explores the role of technology use on agricultural development to understand the ever widening gap of SSA with other global regions. It looks into land (i.e., yield) and labour productivity, the relation between technology use and yield stability and, the environmental implications of input use. Ways and means are discussed as to what innovative technologies could close the gap, taking complex mixed farming systems as an entry point that account for 90% of Africa's agriculture.
