SummaryMaize production is central to rural livelihoods in the hills of Nepal. Access to affordable improved maize seed has long been a barrier to productivity gains and livelihood improvement. This study evaluates the direct and indirect (spillover) impacts of a community-based seed production program in Nepal using a quasi-experimental method for selected outcome indicators. Our results show that community-based seed production provides a significant positive direct impact on maize income and female leadership opportunities. The impacts were particularly favorable for disadvantaged households (HHs) from lower castes and HHs that owned less land. There is also strong evidence of spillover impacts on improved seed adoption, yield, and household maize self-sufficiency. Community-based seed production thereby could help Nepal attain cereal self-sufficiency and nutritional security as envisioned in the national agricultural development strategy and seed vision.

以社区为基础的种子生产的直接和溢出影响:来自尼泊尔的准实验证据

摘要玉米生产是尼泊尔山区农村生计的核心。长期以来,获得负担得起的改良玉米种子一直是提高生产力和改善生计的障碍。本研究使用准实验方法对选定的结果指标评估尼泊尔社区种子生产计划的直接和间接(溢出)影响。我们的研究结果表明,以社区为基础的种子生产对玉米收入和女性领导机会具有显着的积极直接影响。这些影响对来自低种姓的弱势家庭 (HH) 和拥有较少土地的 HH 尤其有利。还有强有力的证据表明,对提高种子采用率、产量和家庭玉米自给自足产生了溢出影响。
