The identification of technological and policy interventions allowing to improve the performance of Beninese rice systems is necessary to reduce the heavy dependence on rice imports. This study characterized the Beninese rice farming systems, identified the production constraints, and determinants of the adoption of improved varieties by farmers. Four hundred eighteen rice farm households were surveyed across 39 villages using participatory research tools and methods. Cluster analysis was used to classify the surveyed farm households and revealed four typologies of rice farming systems differentiated by 8 variables. These are, the intensive rice farming system (cluster 4; 33.7%), semi-intensive rice farming system (cluster 1; 31.8%), integrated rice-livestock farming system (cluster 3; 11.8%), and subsistence rice farming (cluster 2; 22.7%). The integrated rice-livestock farming system was the dominant type practiced in the northern Benin, while, it is the intensive rice farming system in the south. Fifteen production constraints across rice-growing areas were recorded. Our results suggest that to increase adoption of improved rice varieties, agricultural extension services should target landowners' farmers practicing off-season rice production, and having other sources of income. Initiatives to boost rice production in Benin should prioritize the establishment of formal agricultural credit and mechanization option policies.
为减少对大米进口的严重依赖,有必要确定能够提高贝宁水稻系统性能的技术和政策干预措施。本研究对贝宁水稻种植系统进行了特征描述,确定了生产制约因素,并确定了农民采用改良品种的决定因素。在 39 个村庄使用参与式研究工具和方法对 418 户水稻农户进行了调查。聚类分析用于对调查农户进行分类,并根据 8 个变量揭示了四种不同的水稻种植系统类型。这些是集约型水稻种植系统(第 4 组;33.7%)、半集约型水稻种植系统(第 1 组;31.8%)、水稻-畜牧业综合种植系统(第 3 组;11.8%)和自给型水稻种植系统(第 2 组;22.7%)。水稻-畜牧业综合种植系统是在贝宁北部主要实行的种植类型,而集约型水稻种植系统则在南部地区。在各个水稻种植区共记录了 15 个生产制约因素。研究结果表明,为了提高改良水稻品种的采用率,农业推广服务应针对种植反季节水稻和有其他收入来源的土地所有者农民。在贝宁提高水稻产量的举措应优先建立正规农业信贷和机械化选择政策。
