"The economic dependency of Ghana's cocoa sector on pollination services"
by Krumbe, Falk and Arndt Feuerbacher

The cocoa economy of Ghana depends on insect pollination. We use an economy-wide computable general equilibrium (CGE) model with an explicit representation of the ten regions of Ghana to model a decline in the cocoa pollinator population. Model scenarios are guided by a systematic literature review, supplemented with expert interviews. Changes in pollinator populations affect poor and rural households more than urban and rich households. Substantial income losses and decreased food consumption are observed in the Western region, the major cocoa-growing region. Declining cocoa pollinator numbers lead to an increased production of all other agricultural commodities, which considerably benefits the food processing sector. At the same time, the cocoa processing sector suffers high losses. Apart from activities related to agriculture, substantial changes are observed in the mining and finance industry with both considerably increasing their output if pollinator numbers are on the decline.
