ABSTRACT Participatory projects supporting the farmer-based seed management of agrobiodiverse varieties including landraces have proliferated globally in response to nutritional insecurity and climate change. This research examines the agroecological landscape knowledge of farmers in a recent participatory seed project using the tricot approach in Central America. Over 800 smallholder farmers in Nicaragua facilitated on-farm trials of diverse common bean varieties that are nutritiously valuable and potentially well-adapted to increased temperatures and variable precipitation. Our article integrates relevant research concepts in a case study of the agroecological landscape knowledge of 52 participating farmers. Participatory sketch maps, transect walks, and semi-structured interviews were used to identify key areas of farmers’ agroecological landscape knowledge in crop and seed management. Results indicate the prevalence of nine themes of farmer agroecological landscape knowledge. This landscape knowledge exerts major influence on the choice, placement, and management of common bean varieties and associated land use decisions. Our analysis reveals that farmers use this knowledge to manage their landholdings as landscapes of agroecological interactions that guide seed and variety management and affect potential sustainability. Results demonstrate that local agroecological landscape learning is strengthened through and benefits participatory seed projects.

中美洲的参与式种子项目和农业生态景观知识

摘要 为应对营养不安全和气候变化，支持以农民为基础的农业生物多样性品种（包括地方品种）种子管理的参与项目在全球范围内激增。这项研究在中美洲最近使用经编方法的参与性种子项目中检查了农民的农业生态景观知识。尼加拉瓜的 800 多名小农促进了各种常见豆类品种的农场试验，这些品种营养丰富，可能很好地适应温度升高和降水变化。我们的文章将相关研究概念整合到一个案例研究中，对 52 位参与农民的农业生态景观知识进行了研究。参与式草图、样带步行、使用半结构式访谈和半结构式访谈来确定农民在作物和种子管理中农业生态景观知识的关键领域。结果表明农民农业生态景观知识的九个主题普遍存在。这种景观知识对常见豆类品种的选择、放置和管理以及相关的土地利用决策产生重大影响。我们的分析表明，农民利用这些知识来管理他们的土地所有权，作为农业生态相互作用的景观，指导种子和品种管理并影响潜在的可持续性。结果表明，当地农业生态景观学习通过参与性种子项目得到加强并从中受益。这种景观知识对常见豆类品种的选择、放置和管理以及相关的土地利用决策产生重大影响。我们的分析表明，农民利用这些知识来管理他们的土地所有权，作为农业生态相互作用的景观，指导种子和品种管理并影响潜在的可持续性。结果表明，当地农业生态景观学习通过参与性种子项目得到加强并从中受益。这种景观知识对常见豆类品种的选择、放置和管理以及相关的土地利用决策产生重大影响。我们的分析表明，农民利用这些知识来管理他们的土地所有权，作为农业生态相互作用的景观，指导种子和品种管理并影响潜在的可持续性。结果表明，当地农业生态景观学习通过参与性种子项目得到加强并从中受益。
