It is widely recognized that hunger impacts roughly one-third of the global populace, with over one-third of those suffering from undernourishment concentrated in Africa. Agroforestry has emerged as a promising soil fertility improvement technology to address these food security challenges. This study utilizes an endogenous switching regression model, complemented with coarsened exact matching, to ascertain the effects of adopting agroforestry on household food security. We used data from a sample of 615 farms in Southern Rwanda. The findings indicate that the main determinants of agroforestry adoption include secure land tenure, membership in cooperatives, access to credit, household size, and farmers' awareness of agroforestry practices. Findings highlight the substantial contributions of agroforestry to food security, with adopters experiencing 19.81 percentage points higher food consumption scores compared to non-adopters. Moreover, the results reveal potential benefits for non-adopters through agroforestry adoption, thereby suggesting that even individuals who do not currently engage in agroforestry could enhance their food security by considering adoption. These insights emphasize the long-term potential of promoting agroforestry for current and prospective adopters. Policies reinforcing land security, supporting cooperatives, providing accessible credit, and promoting farmer sensitization are crucial for encouraging agroforestry adoption and improving food security. By identifying key determinants and quantifying impacts, this study offers targeted guidance for interventions that leverage agroforestry as a sustainable solution to enhance household food security.

农林业有助于家庭粮食安全吗？卢旺达南部的微观视角


人们普遍认识到，饥饿影响着全球大约三分之一的人口，其中三分之一以上的营养不良人口集中在非洲。农林业已成为解决这些粮食安全挑战的一种有前景的土壤肥力改良技术。本研究利用内生切换回归模型，并辅以粗化精确匹配，以确定采用农林业对家庭粮食安全的影响。我们使用了卢旺达南部 615 个农场的样本数据。研究结果表明，采用农林业的主要决定因素包括有保障的土地保有权、合作社成员资格、获得信贷的机会、家庭规模以及农民对农林业做法的认识。调查结果强调了农林业对粮食安全的重大贡献，采用农林业的农林业的粮食消费得分比未采用农林业的农林业高出 19.81 个百分点。此外，结果揭示了非采用者通过农林业采用的潜在好处，从而表明即使目前不从事农林业的个人也可以通过考虑采用来增强其粮食安全。这些见解强调了为当前和潜在采用者促进农林业的长期潜力。加强土地安全、支持合作社、提供便利信贷和提高农民认识的政策对于鼓励农林业的采用和改善粮食安全至关重要。通过确定关键决定因素和量化影响，本研究为利用农林业作为增强家庭粮食安全的可持续解决方案的干预措施提供了有针对性的指导。
