This leaves rural areas, which have the potential to feed the more than one billion hungry people, cut off and isolated. In sub-Saharan Africa, almost 70% of all people living in rural areas live more than a 30-minute walk from the nearest maintained road.
在非洲，仅有的一些铺好的路都坑坑洼洼，而这些路则连接着一些只能靠特种车辆才能通过的土路。在末端的种植区附近根本无路可走。这等于将那些有潜力养活10亿饥民的农村地区直接切断并隔离开来。在撒哈拉以南非洲，大约有70%的人居住在距离公路30分钟步行距离的农村地区。
