In Burkina Faso, rice is of great importance in terms of consumption and cultivated area. It is the fourth most important cereal crop in terms of area, production and annual per capita consumption. Despite persistently low and almost static yields, demand for rice continues to grow due to high population growth and changing dietary habits. The basic system of local rice production is monoculture in a single annual season for rainfed and lowland rice and in a double annual season for irrigated rice. Irrigated rice is the most efficient rice production method with total control of water supply. However, rice production in Burkina Faso is faced with multiple abiotic and biotic constraints that cause significant yield reductions. Indeed, climatic variability remains one of the most important factors. Like the rest of the Sudano-Sahelian zone, Burkina Faso is subject to climatic hazards, of which the decline and poor spatial-temporal distribution of rainfall has become the main obstacle to rice production. Thus, in a context where the effects of climate change are increasingly perceptible, it is becoming imperative to adopt more efficient varieties and cultivation practices that ensure good water nutrition for the plants. To cope with this situation, an efficient irrigation system is needed to secure and stabilize crops. This situation calls for a careful use of water in agriculture. This review highlights the genetic diversity of rice, its importance, constraints and different rice production systems as well as innovative methods to boost local rice production in the future.

Abstract: (french)
Au Burkina Faso, le riz est d’une grande importance en termes de consommation et de superficie cultivée. Il constitue la quatrième culture céréalière tant du point de vue des superficies, de la production que de la consommation annuelle par tête. Malgré des rendements toujours faibles et quasi stationnaires, la demande de riz continue de croître en raison de la forte croissance démographique et des changements d’habitudes alimentaires. Le système de base de la production locale du riz est la monoculture en une seule campagne annuelle en riziculture pluviale et de bas-fonds et en une double campagne annuelle en riziculture irriguée. La riziculture irriguée est le mode de production du riz le plus performant avec maîtrise totale de l’alimentation en eau. Cependant, la production du riz au Burkina Faso est confrontée à de multiples contraintes d’ordre abiotique et biotique qui causent d’importantes baisses de rendements. En effet, la variabilité climatique, demeure l’un des plus déterminants. A l’instar du reste de la zone soudano-sahélienne, le Burkina Faso est soumis aux aléas climatiques dont la baisse et la mauvaise répartition spatio-temporelle de la pluviométrie est devenue le principal obstacle à la production de riz. Ainsi, dans un contexte où les effets du changement climatique sont de plus en plus perceptibles, il devient impératif d’adopter des variétés plus performantes et des pratiques culturales qui assurent aux plantes une bonne nutrition hydrique. Pour faire face à cette situation, un système d’irrigation efficace est nécessaire pour garantir et stabiliser les récoltes. Cette situation nécessite une utilisation réfléchie de l’eau en agriculture. Cette revue met en lumière la diversité génétique du riz, son importance, les contraintes et les différents systèmes de production de riz ainsi que de méthodes innovantes pour booster la production locale du riz dans l’avenir.
