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.
7pgs, Agricultural subsidies are an important factor for influencing food production and therefore
part of a food system that is seen as neither healthy nor sustainable. Here we analyse options
for reforming agricultural subsidies in line with health and climate-change objectives on one
side, and economic objectives on the other. Using an integrated modelling framework
including economic, environmental, and health assessments, we find that on a global scale
several reform options could lead to reductions in greenhouse gas emissions and improvements in population health without reductions in economic welfare. Those include a repurposing of up to half of agricultural subsidies to support the production of foods with beneficial
health and environmental characteristics, including fruits, vegetables, and other horticultural
products, and combining such repurposing with a more equal distribution of subsidy payments globally. The findings suggest that reforming agricultural subsidy schemes based on
health and climate-change objectives can be economically feasible and contribute to transitions towards healthy and sustainable food systems
