7 pages, Agricultural extension is the medium through which external agricultural technologies have been transferred to and transplanted in Africa to improve agricultural performance. Over a period of close to a century, different agricultural extension models have been proposed but their structure and content has virtually been the same: top-down, linear, non-participatory transfer of technology with no feedback loops for reverse diffusion. This presumably explains the poor performance of Africa’s agriculture and the scale of food security challenges facing the continent. In this review paper, we trace the history of agricultural extension and examine various agricultural extension delivery models to identify their major strengths and weaknesses, using Ghana and Burkina Faso as case studies. We then review the most recent literature in the field about the philosophy, scope, content, delivery, and outcomes of agricultural extension. The conclusion that agricultural extension has consistently remained out of sync with the needs and aspirations of stallholder farmers was reached. Smallholder farmers are now calling for new agricultural extension delivery models that are truly farmer-led, indigenous knowledge-based, context-specific, culturally-relevant and environmentally-sustainable to guarantee efficient farming systems into the future.
5pgs, The Covid-19 pandemic, global trends, and technological advancements lead to the perception that digitalization is about the most sustainable means of growing Africa’s agribusiness and food supply chains. Many global agribusinesses have successfully integrated digital technologies to enhance operational efficiencies and business relations with their upstream and downstream actors. However, evidence is scant on the uptake of digital technologies among small and medium agribusiness firms in sub-Saharan Africa (SSA). Against this backdrop, this review paper identifies research gaps regarding the adoption and implication of digitalization in building sustainable food systems for African economies. Our preliminary finds show some sustainable practices in the SSA food supply chains by adopting specific technologies related to production, grain storage, food waste management, and warehouse management but very low adoption of food processing technologies and digital marketing platforms. Most importantly, the application of the Internet of Things, Big data, Artificial Intelligence, Blockchain and/or Business Analytics is very rare. Most of the digitalization process tends to be mobile-based.
