1. **农业灾害损失巨大**:1991–2023年全球农业损失达3.26万亿美元,年均99亿美元;谷物损失4.6亿吨,果蔬2.8亿吨,肉奶0.9亿吨。 2. **区域与经济影响**:亚洲占全球损失47%(1.53万亿美元),非洲农业GDP损失最严重(7.4%);中低收入国家农业GDP损失5%。 3. **营养与渔业损失**:灾害导致全球日均热量损失320千卡/人,铁损失达男性需求的60%;海洋热浪致渔业损失66亿美元,影响15%全球渔业。 4. **数字解决方案**:数字技术(如AI、遥感)推动灾害风险管理,从被动响应转向主动预警;每1美元预警投入可产生7美元收益,910万农民通过数字平台获得农业保险。 5. **关键挑战**:当前评估工具忽视间接损失、长期影响及非经济价值(如生物多样性),需加强数据整合与多 stakeholder 合作。
农业损失有多大? 数字如何减灾? 渔业被忽视了吗?
