Abstract

Rural Malians depend on sorghum as a staple food. Despite long-term investment in sorghum improvement, achieving major gains in sorghum yields has posed challenges. We assessed the potential economic impact of the first Guinea-race sorghum hybrids developed and diffused using participatory plant breeding with decentralised, farmer-based seed systems. We compared this approach to formal plant breeding with a centralised, state-managed seed system – the sole approach pursued in Mali prior to 2000. To incorporate risk, we augmented the economic surplus model by applying Monte Carlo sampling to simulate distributions of model parameters. A census of sorghum varieties in 58 villages of the Sudanese Savanna served as the adoption baseline. Our findings indicate that research on sorghum hybrids with the new approach is a sound investment. Public and private actors need to continue investing in innovative ways to expand the sorghum seed system. The sensitivity of results to the price elasticity of supply suggests commercialisation opportunities.

几内亚高粱杂交种在马里的潜在经济影响:研究与发展模式的比较

马里农村人以高粱为主食。尽管对高粱改良进行了长期投资，但要实现高粱产量的大幅增长还是面临挑战。我们评估了第一批几内亚高粱杂交种的潜在经济影响，这些杂交种是通过分散的、以农民为基础的种子系统进行参与性植物育种开发和推广的。我们将这种方法与具有集中、国家管理的种子系统的正式植物育种进行了比较，这是2000年之前马里采用的唯一方法。为了纳入风险，我们通过应用蒙特卡罗抽样来模拟模型参数的分布，对经济盈余模型进行了扩充。对苏丹萨凡纳58个村庄的高粱品种进行普查，作为采用基准。我们的研究结果表明，用新方法研究高粱杂交种是一项合理的投资。公共和私人行为者需要继续投资于创新方式，以扩大高粱种子系统。结果对供应价格弹性的敏感性表明了商业化的机会。

期刊介绍： The African Journal of Agricultural and Resource Economics (AfJARE)/Journal Africain d’Economie Agricole et des Ressources (JAEAR) is a publication of the African Association of Agricultural Economists (AAAE). The journal publishes original research about how African agriculture interacts with local and global economic systems and policy regimes in its impacts upon people. The scope of the journal covers the roles of markets, technology, policy, institutions and the natural environment in shaping the lives of well being of Africans engaged in agricultural activities. The journal strives to nurture and enhance the capacity of African professionals to conduct and publish scientific research and provides a venue for communicating and disseminating their findings. Multi-disciplinary, problem-oriented articles are encouraged. Submissions may deal with teaching, research extension, consulting, advising, entrepreneurship and administration. The Chief Editors and Editorial Board, under the general direction of the AAAE President, Executive Committee and Council are charged with implementing Journal policy to serve members of AAAE. The main section of the journal publishes technical research articles while a small section is devoted to publishing brief notes with important policy content and book reviews. The journal is a quarterly publication.
