世界各国的粮食生产
Production of grain in other countries

    

    近年来,全世界粮食产量为20-22亿吨,2011年达到23.2亿吨,中国是世界第一大产粮国家,2011年粮食产量达到5.5亿吨,美国第二,大约5亿吨。全世界的粮食供求关系基本平衡。世界各国的粮食生产政策有很大的差别。美国从2002年起一直把小麦生产控制在8000万吨以下,日本确保大米和牛奶自给。中国确保大米、小麦和玉米的自给率达到100%,对进口豆油和大豆不加限制,以确保95%以上的粮食自给率。新加坡不生产一粒粮食,全部需要进口。非洲一些国家的饥荒则是靠国际救济。
世界主要国家的粮食自给率如下:
美国 法国 德国 英国 日本 俄国 巴西 印度 中国 新加坡
