西アフリカ半乾燥地域における農業生態学的強化（AEI）実践の気候回復力を評価。シミュレーションの結果、コンパニオンクロップなどの輪作は浅い土壌で単作より優れ、有機物施用は収量を増加させるが変動も大きく、残渣管理は地域により効果が異なる。経済性や労働制約を考慮した実証実験が必要。
English
This study assesses the climatic resilience of agroecological intensification (AEI) practices in semi-arid West Africa using the SIMPLACE framework. Results show legume rotations outperform monocropping in shallow soils, organic amendments increase yields but also variability, and residue retention improves yields in some regions without organic inputs. The findings highlight the need for site-specific validation considering economic and labor constraints.

📄 Abstract（原文）
Agroecology is widely promoted to address the environmental impacts of intensive farming and support the UN Sustainable Development Goals (SDGs). However, in semi-arid West Africa, the potential of Agroecological Intensification (AEI) to improve food security remains contested due to severe climate variability, soil degradation, and structural barriers like limited input access and weak extension services. This study assessed the effects of key AEI practices—including legume rotations, dual-purpose sorghum varieties, manure application, and crop residue retention—on the resilience and sustainability of cropping systems under weather variability. Using the SIMPLACE framework, we conducted continuous 10-year simulations (2006–2015) across study sites in Mali, Burkina Faso, and Senegal, capturing weather variability via a large climate ensemble. Results showed that simulated cereal yields in monocropping and rotation systems were similar in deep soils, but rotations outperformed monocropping in shallow soils. Organic amendments increased yields under all conditions, with the highest yields occurring under manure application in Burkina Faso and for grain-only sorghum in Mali. Yield variability was generally higher with manure application than with residue retention. Residue retention improved dual-purpose variety yields in Senegal and Mali, whereas omitting organic inputs consistently increased the risk of crop failure. Soil organic carbon accumulation trends were inconsistent across regions, and nitrogen leaching was higher in shallow soils. Overall, while these findings highlight the potential of AEI, they must be validated by site-specific experimentation that accounts for economic returns, labor constraints, and pest and disease dynamics.
