dc.description.abstractTanzania produces rice from two major ecologies, namely irrigated and rainfed lowland. Currently most of the rice is produced from the rainfed lowland but the country's National Rice Development Strategy (NRDS) hopes to reverse this trend. The NRDS aims to increase the rice production area for irrigated lowland ecology from 200 000 ha in 2008 to 390 000 ha by 2018, with productivity increasing from 2.13 t ha−1 in 2008 to 3.5 t ha−1 in 2018. This study evaluated the performance of irrigated and rainfed lowland rice production using technical efficiency. This paper estimates the technical efficiency of rice production in Tanzania for the irrigated and rainfed lowland ecologies. Data were collected from an irrigated site in Bagamoyo and a lowland rainfed site, Dakawa in the Morogoro area. The study found that the average technical efficiency of the irrigating farmers is 96% compared to an average 39% for the rainfed lowland system. For the irrigated system, there are no farmers with technical efficiency less than 80%. This high technical efficiency indicates that in order to achieve the rice production targets aspired to, the opportunity for increasing production therefore lies in changing the production technology.en_ZA
dc.description.abstractLa Tanzanie produit du riz pluvial irrigué. Actuellement, la majeure partie du riz provient des plaines pluviales, mais la stratégie nationale de développement du riz (NRDS) du pays aspire à inverser cette tendance en augmentant la superficie rizicole irriguée de 200 000 ha en 2008 à 390 000 ha d'ici 2018, pour une productivité passant de 2,13 tonnes par ha en 2008 à 3,5 tonnes par hectare en 2018. Cette étude a évalué la performance des plaines irriguées et pluviales -qui correspondent à deux écosystèmes bien distincts- en utilisant l'efficacité technique,. Les données ont été recueillies à partir d'un site irrigué à Bagamoyo et d'un site pluvial, Dakawa dans la région de Morogoro. L'étude a révélé que l'efficacité technique moyenne des agriculteurs irrigués était de 96 %, et de 39 % en moyenne pour les systèmes de la plaine pluviale. Il n'y a pas d'agriculteurs irrigants ayant une efficacité technique inférieure à 80 %. L'efficacité technique élevée indique que, pour atteindre les objectifs de production de riz, l’augmentation de la production réside donc par la modification de la technologie de production.en_ZA
