Résumé
Little is known about the costs and returns of current bas-fond (saucer swamp) rice production techniques in Eastern Upper Volta, and the possibilities for expanded production. This study gathered detailed input/output data on four major bas-fond rice production systems, differing in degree of water control, in the Eastern Region of Upper Volta. The multiple-Visit activity approach was used ; 116 farmers were interviewed from June, 1980, through February, 1981, at the end of each major field activity (land preparation, weeding, harvesting, etc.). . Financial enterprise budgets for all crops were prepared for each production system. Gross margins and returns to land, family labor and management were computed. Economic costs and returns to the rice enterprises were also analyzed for each production system. In addition, a linear programming model was developed for one representative farm in each production system, to investigate whether and how rice cultivation could be expanded or intensified. The findings showed that the least cost (and economically profitable) technique fbr producing rice is traditional cultivation in unim- ‘ proved swamps. Given current technologies and yield levels, production under improved water control results in negative economic returns. Using financial prices, rice entered the optimal solution in all LPmodels, at acreage levels which held in each system under a wide range of gross margins per hectare. Seasonal family labor supply was found to be critical in determining the maximum level of total gross margins attainable by the farmer from cropping activities.’ Although rice is the only feasible rainy-season crop on bas-fond land, this result implies that price policy alone may not stimulate expanded or intensified rice production. However, higher producer prices and a more productive technological package for rice would increase yields and help justify further investment in water control. The policy recommendations of this study stress the need (1) to de-emphasize major investments in dam irrigation and to give priority to partial water control and rainfed agriculture, (2) to develop a package of improved rice production practices using the Farming Systems Research approach, and (3) to revise the producer price of paddy as an incentive to domestic rice farmers.
