    Governance of emerging biomass-based value webs in Africa : case studies from Ghana
    (2018) Poku, Adu-Gyamfi; Birner, Regina
    Rising global demand for food as well as for feed and biomass-based raw materials such as fuel and fibre crops has increased pressure on the agricultural sector, especially in Sub-Saharan Africa. The expected trend of increased demand for more diverse biomass-based produce from agricultural land effectively transforms the agriculture sector from just a food-supplying to a biomass-supplying sector in the growing international bioeconomy. This transition is leading to the development of biomass-based value webs whereby there are complex systems of interlinked value chains in which food, fodder, fuels, and other raw materials are produced, processed, traded and consumed. Against this background, this thesis aims to evaluate the appropriate roles of the public, private and third (civil society) sectors in facilitating the transformation of the agricultural sector in the developing bioeconomy in Ghana. The study focuses on the emerging value webs of cassava (Manihot esculenta) and maize (Zea mays), which are the two most important staple crops in Ghana.
