Fonio (Digitaria exilis (Kippist) Stapf) and Bambara groundnut (Vigna subterranea (L.) Verdc.) are native crops grown at a small scale in Mali that have potential to support agricultural productivity under climate change. A community biodiversity management approach was explored in this study as a means to reinforce the cultivation of these crops by increasing farmers' access to intraspecific diversity and developing capacities of community institutions for their management. The research involved six communities in Ségou and Sikasso regions. Multiple varieties of fonio (10–12) and Bambara groundnut (8–12) were established in diversity fields in each site over 2 years where farmers engaged in experiential learning over the crop cycle. Significant adoption of fonio and Bambara groundnut was detected in several study sites. The precise drivers of adoption cannot be definitively determined but likely include increased seed access and awareness gained through the diversity field fora, seed fairs and community seed banks. No significant yield advantage was detected for any of the varieties in the diversity fields, which showed variable performance by site and year. The number of varieties registered and managed by community seed banks in each site increased from 1–5 varieties of each crop to 11–12 varieties following the interventions. The number of Bambara groundnut varieties cultivated in farmers' fields also increased, while there was evidence of a slight decline in fonio diversity in some communities. The results of this study can inform efforts to strengthen seed systems and cultivation of neglected and underutilized species in Africa.

通过社区生物多样性管理方法振兴马里的 fonio 和 Bambara 花生的种植和种子系统

福尼奥 (洋槐(Kippist) Stapf) 和班巴拉花生 (地下豇豆(L.)佛得克。) 是在马里小规模种植的本土作物，具有在气候变化下支持农业生产力的潜力。本研究探索了社区生物多样性管理方法，作为加强这些作物种植的一种手段，通过增加农民获得种内多样性的机会和发展社区机构的管理能力。该研究涉及塞古和锡卡索地区的六个社区。在 2 年多的时间里，在每个地点的多样性领域建立了多个 fonio (10-12) 和 Bambara 花生 (8-12) 品种，农民在作物周期中进行体验式学习。在几个研究地点发现大量采用 fonio 和 Bambara 花生。采用的确切驱动因素无法明确确定，但可能包括通过多样性领域论坛、种子交易会和社区种子库增加种子获取和意识。多样性领域中的任何品种均未检测到显着的产量优势，其表现因地点和年份而异。干预后，社区种子库在每个地点登记和管理的品种数量从每种作物的 1-5 个品种增加到 11-12 个品种。农民田间种植的 Bambara 花生品种数量也有所增加，但有证据表明某些社区的 fonio 多样性略有下降。这项研究的结果可以为加强非洲种子系统和种植被忽视和未充分利用的物种的努力提供信息。
