Can orange fleshed sweet potatoes processing trigger farmers to use quality improved planting materials? Empirical evidence from selected regions in Tanzania

January-March 2021

Production of orange-fleshed sweet potato (OFSP) in Tanzania is constrained by the underutilization of virus-free improved certified planting materials. The sustainable use of these planting materials leads to the constant demand of the planting materials by farmers which can be triggered from viable processing. We determine the viability of processing in the OFSP value chain and its contribution to the uptake of...

Traditional solar salt production in Lower Casamance (Senegal): Environmental and socio-economic benefits and disadvantages

February, 2021

To produce salt, women in Lower Casamance (southern Senegal) traditionally practice artisanal fire salt-farming (AFS) by heating a brine with a biofuel (mangrove wood). The thermal energy produced favors the evaporation of water, the saline concentration and the precipitation of crystallized salts. In recent years, artisanal solar salt-farming (ASS) has been introduced in the region using the thermal energy provided by...
