Determinants of NERICA Adoption in Uganda Based on Duration Analysis

抄録

As a major factor for the attainment of the “Green Revolution” in Sub-Saharan Africa, wide attention has recently been paid to new cultivars of rice, called NERICA. Though the diffusion of NERICA had been rapid, planting is being discontinued by many farmers after a few years. An important issue for NERICA dissemination is how to extend the duration of adoption. In the present study, the determinants of NERICA adoption were identified by the method of duration analysis, based on data collected through interview surveys of farmers in Uganda. We observed that farmers discontinued NERICA production at early stages of the adoption process and that drought occurrence and long distance to rice mills decreased the adoption duration of NERICA, while membership of farmers’ groups contributed to the continuation of NERICA adoption. Our study suggests that in order to promote the adoption of NERICA in Sub-Saharan Africa, it is essential to reduce the fluctuations in rice yield due to erratic weather conditions through the implementation of water control measures, the development of post-harvest markets, and membership of farmer groups that maximize “social learning.”
