人们普遍认识到，要将农业生产提高到养活不断增加的世界人口所需的水平，就需要大幅增加对研究和开发的公共投资，并广泛采用新技术，但近年来，国家和国际农业研究的资金却有所减少。在这种情况下，确定优先事项对于在相互竞争的需求之间分配稀缺的研究资源以实现更大的影响变得越来越重要。本文利用部分平衡经济盈余模型和贫困影响模拟，根据替代研究和技术选择的潜在经济和减贫影响，评估了非洲、拉丁美洲和加勒比以及亚洲的木薯研究优先事项。结果表明，高效的种植材料生产和分配系统以及可持续的作物和土壤肥力管理做法在这三个区域具有最大的预期经济和减贫影响。缺乏清洁的种植材料是采用的一个主要制约因素，据设想，有效的种植材料生产和分配系统可以加速农民采用技术。同样，可持续的作物和土壤肥力管理做法在缩小已观察到的产量差距方面发挥着关键作用，特别是在非洲。本文讨论了木薯研究重点的优先评估结果，并得出结论，木薯研究优先事项的影响。
It is widely recognized that increasing agricultural production to the levels needed to feed an expanding world population requires sharply increased public investment in research and development and widespread adoption of new technologies, but funding for national and international agricultural research has rather declined in recent years. In this situation, priority setting has become increasingly important for allocating scarce research resources among competing needs to achieve greater impacts. Using partial equilibrium economic surplus models and poverty impact simulations, this paper assesses cassava research priorities in Africa, Latin America and Caribbean, and Asia based on the potential economic and poverty reduction impacts of alternative research and technology options. The results showed that efficient planting material production and distribution systems and sustainable crop and soil fertility management practices have the greatest expected economic and poverty reduction impacts in the three regions. Lack of clean planting materials is a major constraint to adoption and it is envisaged that efficient production and distribution systems for planting material can accelerate technology adoption by farmers. Similarly, sustainable crop and soil fertility management practices play a key role in closing the observed yield gaps, especially in Africa. The paper discusses the results of the priority assessment for key cassava research options and concludes with the implications for cassava research priorities.
