城市农业因其对粮食安全和减贫的贡献而得到推广。相当多的文献强调了这些好处，但也有批评说，他们被夸大了。我们审查这些不同的观点和评估的潜力，UA有助于在不同地区的城市粮食安全，基于低门槛的城市土地需要增长的每日蔬菜摄入量的城市穷人。我们发现，普遍获得在这些方面在高收入国家是可行的，但其潜力很低，除非在最乐观的情况下，在低收入国家，它可能是最有用的。我们的结论是，普遍获得服务在低收入国家实现城市粮食安全方面只能作出有限的贡献。(C)2014爱思唯尔有限公司版权所有。
Urban agriculture (UA) is promoted because of its contribution to food security and poverty alleviation. A considerable literature highlights these benefits, but there are also criticisms that they are overstated. We review these divergent perspectives and assess the potential for UA to contribute to urban food security in different regions, based on a low threshold of urban land required to grow the daily vegetable intake for the urban poor. We find that UA is feasible in these terms in high-income countries, but its potential is low, except in the most optimistic scenario, in low-income countries, where it might be most useful. We conclude that UA can only make a limited contribution in achieving urban food security in low-income countries. (C) 2014 Elsevier B.V. All rights reserved.
