Lasting from June to September, the rainy season brings out a socio-economic behaviour which demonstrates its effect on not only the local population’s everyday life but also on the importance of stock-breeding as source of revenue and, more importantly, food. Ayoun El Atrouss is the main town and regional capital of Hodh El Gharbi in Castern Mauritania. In 1988, its population numbered 14,666 inhabitants. The climate is typically Sahelo-Saharan and the mean annual rainfall between 250 and 300 mm. The main behaviour type linked to the rainy season is a mass exodus from town to country or badiya. During the rainy season, the place of residence, or khariv, varies in terms of location and distance from the town from one family to the next. Most people explain their departure by saying they want to drink milk again, but there are other, unwillingly admitted, reasons of a financial nature (reducing expenditure for example). How much more or less money is spent will often depend on where and how far away the badiya is. A particular type of public transport also develops during the rainy season; of great socio-economic importance, if differs from classical transport in terms of both standards and location. The khariv period lasts several months. In October, the start of the school year forces most families to adopt a set of strategies reconciling the desire to remain in the country and the need to send their children to school. The final return of the population as a whole occurs essentially in January-February with the onset of winter and the thin end of the water and posture wedge.
