, comme autre indicateur de l'intensité du choc pluviométrique. Nous adoptons une variable binaire qui prend la valeur 1 si le coefficient de variation des précipitations entre l'année précédente et l'année d'enquête, est supérieur ouégal au seuil de 20 % et de 0 dans le cas contraire. Cette variable permet de déterminer l'intensité de la sécheresse (Turkes, 1996) en supposant que les zonesà forte variation de précipitations sont plus touchées par les sécheresses que les zones moins sensibles aux chocs, Pour vérifier davantage la robustesse de nos résultats, nous utilisons le coefficient de variation, exprimé sous forme d'écart-type en pourcentage de la moyenne, 2005.
