This article has used a multinomial logit model to analyze the determinants of diversification strategies of rural households' income sources in Burkina Faso. The main results have enabled the identification of three strategies of the income-source diversification, all carried out around agriculture. They are low, average, high diversification strategies. The outcomes reveal that the age of the household head, household size, dependency ratio, acreage, membership of a producer group, amount of credit, agricultural potential of the area, morbidity, distance to a main road, access to a radio, total income and technical assistance were the key factors in determining the level of income diversification. They indicate that the diversification of income sources is both a strategy for managing risk of fluctuations in agricultural income and a means to take advantage of opportunities in the production environment, given the constraints of rural households.

Dans cet article, un modèle économétrique de la fonction distance multi-outputs a été utilisé pour analyser les effets des services sociaux sur l’efficacité technique des exploitations agricoles burkinabè. Les résultats montrent que le nombre d’années d’éducation formelle reçu par le chef de ménage, l’expérience de la pratique agricole, la fréquentation des centres de santé moderne et les services de soutien à la production agricole ont des effets positifs significatifs sur l’efficacité technique.

This article has used the method of instrumental variables to evaluate the impact of health services on the productivity of rural households’ farming labor in Burkina Faso. The distance from the household's homestead to the Health and Social Promotion Center (HSPC) was considered as an instrumental variable. The results revealed that resorting to a HSPC in case of an unexpected illness in the rainy season significantly improves the farm labor productivity by FCFA 3170.5880 per person-day. For improving agricultural productivity, we suggest that public decision-makers should focus on the availability and the quality of HSPC services in rural areas.

Background Dry spells are serious obstacles to rainfed agriculture in Sahelian countries. Various water harvesting techniques are used by farmers to reduce the impact of climate variability, but are not sufficient in the case of a prolonged drought lasting 2–3 weeks. The farmers believe supplemental irrigation is a good way to adapt rainfed agriculture to dry spells. In this study, we evaluated the food contribution and profitability of supplemental irrigation of rainfed crops comparing various farm ponds that collect runoff water from the surrounding landscape. Methods We analyzed the contribution of supplemental irrigation to food security and compared the profitability of different types of ponds constructed by farmers in northern Burkina Faso. Human cereal requirement was used as indicators to analyze the contribution of supplemental irrigation to food security. The criteria for analyzing the profitability of the selected ponds were gross margin (GM), net present value (NPV), internal rate of return (IRR) and payback period (PBP). Results Our results show that the additional yield of corn obtained with supplemental irrigation makes it possible to meet the monthly cereal needs of at least 17 people and generates an additional GM of FCFA 178,483 (US$ 309.26) compared to no irrigation. The estimate of the NPV, from IRR and PBP showed that the profitability of supplemental irrigation in 15 agricultural seasons varies between the type of ponds constructed. Conclusions Given the up-front cost and the farmers’ lack of resources, the ponds require a subsidy or a credit policy to facilitate the adoption of supplemental irrigation in Sahelian countries. However, the irrigation strategies to optimize agricultural income remain a field of research to be explored.
