Abstract: Determinants of clove exports in Zanzibar – Implications for policy

This paper analyses factors for the declining trend in clove export in Zanzibar using time series data collected between 1980 and 2020 analysed using Vector Error Correction Model complemented with qualitative approach. Clove production, producer price, world price, Gross Domestic Product, and Exchange Rate showed positive statistically significant impact in a long-run at one percent level; while Foreign Direct Investment, population growth rate, rainfall and Gross Capital Formation showed significant negative association. Inflation had no impact.

Qualitatively, clove export was determined by: (i) factors that affected clove production because of poor extension services (ii) low and or fluctuation of the clove price; inferring that quantitative and qualitative results coincided. We can conclude that clove export was determined by many interlinked factors. Other factors affected clove export indirectly through clove production. We recommend an integrated policy approach that takes on board, comprehensively, all determining factors to improve and sustain clove export.
