Positioning smallholder farming in the agricultural productivity and food security in resource limited Sierra Leone

Agriculture is dominated by smallholder farmers who occupy the majority of land, and produce most of the crop and livestock products in Sierra Leone. Nonetheless, the key long-standing challenge of the smallholder farmers is low productivity that stems from the lack of access to markets, credit and technology, and in recent years these are compounded by the volatile food and energy prices and very recently by the global...
