EXPLOITATION OF LOCAL KNOWLEDGE OF FARMERS ON FLUOROSIS FOR MAPPING SOIL IN MOROCCO WESTERN CENTRAL: CASE OF BENI MESKINE, PROVINCE OF SETTAT.

Fluorosis is a major constraint for the sheep \'\' Sardi \'\' in the region of Beni Meskine in Morocco. The objective of this study is to explore the local knowledge of farmers for fluorosis, its causes, impacts, spatial distribution, and strategies for mitigation. To meet these objectives, workshops and surveys were conducted with the breeders of the study area. The results of this study indicates that the local population is very aware of the distribution and mapping of its territory on the soil to fluorosis. Most of the population is aware that the soil and the drinking water cause the problem of fluorosis. Two cards based on local expertise were established for the first time to this area and that concern: a) a Fluorosis distribution map and b) a card that summarizes the main mitigation strategy. This information can be used for action plans to set up to target the mitigation of fluorosis by the departments concerned. It also used to establish a research program on soil mapping according to their fluoride content to a confrontation of approaches / scientific methods with those of the local knowledge of farmers.
