报告显示，利用一系列气候情景和模型进行的预测表明，极端高温使农食系统受损的趋势将继续恶化。 全球平均气温每升高1摄氏度，玉米和小麦等主要农作物产量预计将下降4%至10%。 联合国政府间气候变化专门委员会主席吉姆·斯基在一份公报中说，农食系统是受气候变化影响最严重 的行业之一，干旱和极端高温已经使传统的风险管理措施不堪重负。他强调，气候变化正在改变作物产 量、牲畜生产力、水资源供应和生态系统功能等，而所有这些都对粮食安全、生计、营养和生物多样性 产生直接影响。 新华财经巴西贝伦11月21日电 联合国粮农组织和世界气象组织20日在巴西联合发布《极端高温与农 业》报告，强调极端高温对农业与食物系统（农食系统）构成多重风险，指出迫切需要以科学为依据的 解决方案来增强农业的韧性和可持续性。 该报告还研究了巴基斯坦、摩洛哥、智利和葡萄牙等国关于极端高温带来连锁反应的案例，并提出风险 治理办法，例如实施可持续灌溉措施，以及通过气候科学和信息指引下的相关实践来减缓气候变化等。 这份报告在巴西贝伦举行的《联合国气候变化框架公约》第三十次缔约方大会（COP30）的一场主题 为"通过气候科学改造农食系统"的边会上发布。报告说，极端 ...

联合国粮农组织和世界气象组织20日在巴西联合发布《极端高温与农业》报告，强调极端高温对农业与 食物系统（农食系统）构成多重风险，指出迫切需要以科学为依据的解决方案来增强农业的韧性和可持 续性。 这份报告在巴西贝伦举行的《联合国气候变化框架公约》第三十次缔约方大会（COP30）的一场主题 为"通过气候科学改造农食系统"的边会上发布。报告说，极端高温损害农牧业，使渔业资源衰退，并威 胁着全球约12.3亿人的生计。气候变化还大幅增加了农业劳动者因高温作业而死亡的风险。据统计， 2021年全球因极端高温损失4700亿工时。 联合国政府间气候变化专门委员会主席吉姆·斯基在一份公报中说，农食系统是受气候变化影响最严重 的行业之一，干旱和极端高温已经使传统的风险管理措施不堪重负。他强调，气候变化正在改变作物产 量、牲畜生产力、水资源供应和生态系统功能等，而所有这些都对粮食安全、生计、营养和生物多样性 产生直接影响。 该报告还研究了巴基斯坦、摩洛哥、智利和葡萄牙等国关于极端高温带来连锁反应的案例，并提出风险 治理办法，例如实施可持续灌溉措施，以及通过气候科学和信息指引下的相关实践来减缓气候变化等。 （文章来源：新华网） 报告 ...
