Abstract:This paper analyses the impact of climate variability on cereal, root and tuber crops diversification for selected West Africa countries during the period 1965–2014. Crop diversification index, lumping together cereal, root and tuber crops, was calculated through the Composite Entropy Index. Climate variability is measured by the coefficient of variation of temperature and precipitation. A Seemingly Unrelated Regression was used to estimate the relationship between climate variability and crop diversification … Show more
