To study the evolution of the alimentary bolus in relation with the loss of forest cover in the Congo Basin, we conducted semi-structured surveys on the composition, origin and amount spent to prepare meals in three study sites with a contrasted forest cover gradient. At global level, the cost price of meals increases as the forest cover decreases. The share of the alimentary bolus in relation with the use of natural resources such as hunting, fishing and harvesting drops to the benefit of proteins from livestock and agricultural commodities. This leads to a translocation of the demand but also pressures on other anthropized ecosystems. The effects of deforestation are subsequently felt at local level but also in neighboring areas.
