1. **土壤健康与粮食安全**:撒哈拉以南非洲(SSA)65%的耕地退化,导致农业生产力低下,20.2%人口面临饥饿(全球最高),土壤养分年损失达40亿美元。 2. **化肥使用不足**:SSA氮肥平均用量仅13.3公斤/公顷(全球平均65.4公斤),因价格高、供应链弱、需求受限(如小农风险规避、信息不足)。 3. **政策与投资方向**:需综合施策,包括改善土壤健康(如综合土壤肥力管理ISFM)、提升本地化肥生产、降低成本(如基础设施投资)、差异化激励(如针对小农的风险缓冲措施)。 4. **区域合作**:呼应《非洲肥料与土壤健康行动计划》(2024–2034),强调通过多边合作(如欧盟、FAO)推动可持续农业转型,平衡短期粮食需求与长期土壤健康。
