Abstract
Efforts to improve the productivity of food crops as yam have increased through the implementation of adaptation methods in Cote d’Ivoire. These efforts are aimed at achieving food security as part of the United Nations’ Sustainable Development Goal 2. In fact, food security, which has been the main objective of developing countries for many years, is undermined by climatic variations. However, these climatic variations caused several damages to the food crop, particularly on yam crop which is one of the important food in the country in terms of production. Therefore, in this study, we analyze the effects of climate variations on the productivity of yam crops produced in Cote d’Ivoire. To carry out this study, we were inspired by the Ricardian analysis developed by Mendelsohn. This analysis has been adapted to our concerns by linking a set of climate variables such as temperature and precipitation with the productivity of the yam crops. The data used in this study are time series that covers the period from 1980 to 2015. The results obtained from the error correction model indicate that the productivity of yam crops has as variables that influence its short-run productivity the precipitation, the growth rate of the rural population, crude rate of mortality, and agricultural employment while in long-run all variables include in the model influence it except access to electricity in rural. Also, the relationship between climate variables and the productivity of yam crops studied is non-linear. This relationship is concave for temperature and convex for precipitation.
