Impact of Climate Change on Date Production in Tunisia

Abstract

Around the Mediterranean basin, climate change is one of the major phenomena affecting agriculture. Therefore, the mode of production and crop management will have to change radically. Our objective in this article is to examine the long-run effects of climate change on date production in Tunisia using panel cointegration covering the period from 1980 to 2014 in 24 regions. The climate of Tunisia differs in our study because we find a Saharan climate in the south and a European climate in the north. The central regions are characterized by a Mediterranean climate. Our empirical results show that the effects of climate and weather variability on date production must be considered a serious threat in Tunisia. In addition, we estimate relatively negative and variable long-run effects of temperature increase and rainfall shortages across regions on date output over the last three decades.
