全球人口从2010年的70亿增长到2050年预测的98亿,整个发展中世界的收入增长,总体粮食需求自然增长50%以上,动物类食品需求增长近70%数以亿计的人仍然挨饿, 农业已经使用近一半的世界植被土地, 农业及相关土地使用变化产生四分之一的年温室气体排放
菜单可持续食品未来
  • 课程1:减少对食品和其他农产品需求增长
    规模食物挑战-相关环境经济挑战-依赖到本世纪中叶对作物和动物类食物需求增加的规模粮食、土地和温室气体缓解差距取自对作物和牲畜需求常态增长的合理估计然而,这种增长水平并非不可避免。课程一菜单项探索如何减少社会和经济上有利增长预测
  • 课程2:增加粮食生产而不扩展农地
    除课程1处理的减少需求措施外,世界必须提高现有农地的粮食输出量要实现净零扩展农地目标,在现实假设下,提高作物和牧场生产率必须超过历史增产率
  • 课程3:保护和恢复自然生态系统和限制农业土地移植
    本课程侧重于土地管理努力,这些努力必须补充减少粮食需求努力和生产率增益,以避免农业用地扩展的危害一项指导原则是需要作出提高所有目的效率的土地使用决策-不仅是农业,而且还有碳存储和其他生态系统服务另一项原则是需要明确地将提高农业产量增益与保护自然土地联系起来。
  • 课程4:增加鱼供应
    鱼,包括有鳍鱼和贝类,只提供全球总热量和蛋白质的微小百分比,但它们提供17%动物蛋白,对于发展中国家30多亿人尤其重要。预测2010至2050年间鱼消费量上升58%,但野生鱼捕获量在1990年代中期达到9 400万吨峰值并自此停止或也许下降本课建议改进野生渔业管理和提高水产养殖生产率和环境性能的方法
  • 课程5:减少农业生产温室气体排放量
    农业生产排放来自畜牧养殖、氮肥应用、水稻种植和能源使用传统上认为这些生产过程难以控制总体说来,本课程对减缓潜力的估计比其他人更乐观,部分是因为许多分析没有完全捕捉提高生产率的机会,部分是因为我们考虑技术创新有希望的潜力
