Although development intervention programs can have far‐reaching impacts beyond their stated objective, there have been few careful studies on associated but unintended outcomes of such programs. This study assesses the impact of membership in the public works component of Ethiopia's productive safety net program (PSNP) on whether households use manure and the amount of it they use. This is done using the double‐hurdle method based on survey data of 2015 on 11 agro‐climatically diverse districts of the Tigrai region in Northern Ethiopia. Results show that PSNP member households are not different from their nonmember counterparts in terms of manure use. This may indicate that PSNP is helping member households catch up with nonmember households in terms of manure use, even though they have smaller livestock ownership. This might indicate that PSNP member households are becoming more aware of the benefits of using manure, and hence are using available manure more efficiently. Therefore, this could be taken as one additional positive contribution of the PSNP in Ethiopia's endeavor to improve food security of poor rural farm households by increasing their productivity.

埃塞俄比亚生产安全网计划对农村家庭使用粪便的影响：来自埃塞俄比亚北部提格拉的证据

尽管发展干预计划可能会产生超出其既定目标的深远影响，但很少有人对此类计划的相关但意想不到的结果进行认真研究。这项研究评估了埃塞俄比亚生产安全网计划（PSNP）的公共工程部分成员资格对家庭是否使用肥料及其使用量的影响。这项工作是基于2015年埃塞俄比亚北部提格拉地区11个农业气候不同地区的调查数据的双关方法进行的。结果表明，PSNP成员家庭在粪便使用方面与非成员家庭没有差异。这可能表明PSNP正在帮助成员家庭在粪便使用方面赶上非成员家庭，即使他们拥有较少的牲畜所有权。这可能表明PSNP成员家庭越来越意识到使用肥料的好处，因此更加有效地利用了可用的肥料。因此，这可以作为PSNP在埃塞俄比亚通过提高生产力提高农村贫困农户的粮食安全的努力中的另一项积极贡献。
