During the last decade, the Niger’s population has been affected by the food crisis (2001, 2004-2005, 2008, 2010-2011). Each year, she is subjected to many structural and temporary shocks. The structural shocks are caused by the chronicle difficulties (income) while the temporary shocks are tied at the "natural" disasters such as the hydrometeorological disasters, demographic crisis. The risk that the people fall in a state of food insecurity because of structural and temporary shocks is characterized by food vulnerability. The food vulnerability is defined as “the analysis of coping strategies and reactions faced with the structural or/and temporary shocks, if the coping strategies are not effectives, the people have in a temporary or structural food vulnerability” (Andres L. and Lebailly Ph., 2011). The target of this paper is to demonstrate the diversity of coping strategies in the different departments of Niger. The database is created as from an annual survey realized by the Early Alert System (EAS) and the Statistical National Institute of Niger (INS). This survey characterizes the state of food insecurity of households of Niger. The investigations of the household are based on stratified sampling. It exists two levels: region and enumeration areas. The investigations of the household are based from the database of the population census of 2001. This population census has determined the “enumeration areas”. These “enumeration areas” are defined as a “geographical area of 200 households on average” (INS, 2007). The sample of this investigation is established from a significant sample a point of view of the departments of Niger. The time period studied is spread the 2008 at 2011. The results have demonstrated that the departments of Tchintarabaden, Abalak, Tessaoua and Magaria have weakest number of collective meals, and the highest percentage of household practicing of selling the goods and land. Furthermore, the Niger’s population develops many strategies to struggle against the shocks.
