Soil degradation is a major cause of agricultural productivity decrease in sub-Saharan Africa. In Burkina Faso, efforts to reduce this environmental issue has emerged since several decades. However, most of the techniques developed are rarely adopted by farmers. In addition, those adopted are on small areas. This study aims to analyze the effect of farmers' preferences for soil and water conservation techniques' attributes on their intensity of adoption. Cross-sectional data was collected from 335 farmers in four rural municipalities in Burkina Faso, using a discrete choice experiment approach. The standard Tobit model was used for data analysis. Results showed that soil and water conservation techniques' attributes as runoff reduction, soil fertilization and soil restoration explained farmers' decision to adopt and intensify the adoption of these techniques. In addition, location in the northern sudanian agroecological zone, access to extension services and education influenced positively soil and water conservation techniques' adoption intensity. However, equipment, labor and cash constraints decrease these techniques' adoption intensity. These results suggest that incentives for the adoption and intensification policies should be oriented toward farmers' capacities to produce quantity and quality organic fertilizers reinforcement, build an industrial unit to transform household waste into organic manure for agricultural use.
土壤退化是撒哈拉以南非洲农业生产力下降的主要原因。在布基纳法索，几十年来一直在努力减少这一环境问题。然而，所开发的大多数技术很少被农民采用。此外，那些被采用的技术应用面积也很小。本研究旨在分析农民对水土保持技术属性的偏好对其采用强度的影响。采用离散选择实验方法，从布基纳法索四个农村市镇的335名农民那里收集了横断面数据。数据分析采用标准托比特模型。结果表明，减少径流、土壤施肥和土壤恢复等水土保持技术属性解释了农民采用和加强采用这些技术的决定。此外，位于苏丹北部农业生态区、获得推广服务和教育对水土保持技术的采用强度有积极影响。然而，设备、劳动力和资金限制降低了这些技术的采用强度。这些结果表明，促进采用和强化政策的激励措施应着眼于增强农民生产数量和质量有机肥料的能力，建立一个工业单位将家庭废物转化为农业用有机肥料。
