Priorisation des pratiques anti-érosives de conservation des sols dans la zone soudanienne au Bénin (Afrique de l’Ouest)

Prioritization of anti-erosion practices for soil conservation in the Sudanian zone in Benin (West Africa) The commune of Ouaké is part of the Sudanese zone of Benin where the advanced soil degradation is observed. In order to contribute to the restoration of these soils, anti-erosion practices of soil conservation (APSC) were evaluated in this commune. Surveys and data collection were carried out from individual and group interviews with 215 farmers in 18 villages, covering all the districts of the commune, as well as at the level of agricultural and forestry development structures. A diagnosis was carried out on each APSC by identifying their strengths, weaknesses, opportunities and threats followed by their prioritization. A total of five (05) anti-erosion practices have been identified with a predominance of the practice of furrows in a direction perpendicular to the slope (80.63 %). The adoption rate of these APSC differs according to the villages and districts, socioeconomic groups, ethnicities, sex, age, level of education and main activity. Anti-erosion hedges and stony cords have high priority. The development of APSC must be based on these priority practices.
