Low intake of fruits and vegetables is a major cause of micronutrient deficiencies in the developing world. Since the 1980s, various non-governmental organizations have promoted homestead gardening (HG) programs, first in Asia, but now increasingly in Africa. Longstanding concerns with HG programs are: (1) they lack scalability, particularly for governments; (2) they only work in areas with/without good access to markets; and (3) they are only suitable for more water-abundant ecologies. We assess these concerns by analyzing a large and novel survey on the adoption of a nationwide HG program implemented by the Ethiopian government. We find that better market access encourages HG adoption; so too does greater public promotion of HGs, but only in more water-abundant ecologies.
水果和蔬菜摄入量低是发展中世界微量营养素缺乏的主要原因。自20世纪80年代以来，各种非政府组织一直在推广家庭园艺（HG）项目，先是在亚洲，如今在非洲也越来越普遍。对家庭园艺项目长期存在的担忧包括：（1）它们缺乏可扩展性，尤其是对政府而言；（2）它们只在有/没有良好市场准入的地区有效；（3）它们只适用于水资源较为丰富的生态环境。我们通过分析一项关于埃塞俄比亚政府实施的全国性家庭园艺项目采用情况的大型全新调查来评估这些担忧。我们发现，更好的市场准入会鼓励采用家庭园艺；对家庭园艺的更多公共推广也会起到同样的作用，但前提是在水资源较为丰富的生态环境中。
