Knowledge of the characteristics of upland rice cultivation systems is a lever for the development of rice cultivation in Burkina Faso. This study aims to highlight the typology of upland rice cultivation systems in three localities: East, Hauts Bassins and Central Plateau regions of Burkina Faso. A survey was carried out among a sample of 293 producers in the localities concerned. The Multiple Correspondent Analysis identified three upland cultivation systems: the low-intensive Upland rice cultivation system with rotation (SCRPS1); the Intensive Upland Rice Cultivation System (SCRPS2) and the low-Intensive Upland Rice Cultivation System without rotation (SCRPS3). Elements that make it possible to distinguish the systems are: age, sex, level of education of the farmer, upland rice area, equipment, crop rotation, type, quantity and the number of fertilizers used in upland rice system. The practices of cropping systems differ from one locality to another. In short, the SCRPS1 type is the most practiced by producers and the SCRPS2 type with a high yield (2759.04 kg / ha) presents itself as an interesting prospect to promote for rice production generating income for an improvement of income women farmers.

The purpose of this study is to analyze the determinants of farmers' willingness to pay (CAP) amounts for the use of microdose technology components on farms in the Kourittenga and Zondoma provinces of Burkina Faso. Faced with the precariousness of the productivity of their lands, farmers make investments in the practice of innovative microdose technology to improve and maintain the productive capital of crop plots. However, the factors determining the amounts granted for the practice of the components are little known. The literature in this area is generally focused on the perception of technology adoption and less on the determinants of investment and willingness to pay. The purpose of this study is to analyze the determinants of farmers' willingness to pay (CAP) amounts for the use of microdose technology components on farms in the Kourittenga and Zondoma provinces of Burkina Faso. A survey was conducted among 360 farm households in municipalities in both provinces and the data were collected using a semi-structured questionnaire. Heckman's two-stage selection model was used for this study The results of the analysis revealed that: experience in microdose technique, social status, area, land tenure and distance from fields are factors influencing willingness to pay reported by farming households for the practice of the components 'Stony Cordons + Compost + Microdose'; the 'Zai + Compost + Microdose' and the 'Zaï + Manure + Microdose'. While household size, available area, level of education, literacy and farm income influence the amounts reported by farmers. However, the great heterogeneity of farmers' characteristics and the different contexts impose case-by-case options in order to take into account local specificities.
