This study examines farmers' decisions to engage in subsistence home-gardening and its impact on food and nutrition security among farm households in Rwanda under diverse conditions. The study uses a nationally representative dataset from Rwanda from 2012, 2015, and 2018. We employ an endogenous switching regression model to jointly estimate the drivers of home-gardening participation decisions and food and nutrition security outcomes, whiles accounting for selection bias from observable and unobservable factors. We also estimate the treatment effects of home-gardening participation on dietary diversity, food consumption score, and anthropometric markers of women and children. The treatment effects are calculated at sample means and connected to market-related variables, such as land ownership, commercialization extent, and market distance. We find that having a home-garden is linked to improved dietary diversity and better nutritional outcomes. If households have restricted access to land and reside further away from marketplaces, the benefits are larger. In contrast, the benefits of home-gardening are positive and significant regardless of the level of commercialization of production. We also discover that family size, gender, education, access to land, and livestock ownership are statistically significant drivers of home-gardening participation in Rwanda. However, the amount of commercialization did not affect a household's decision to participate in home-gardening.

本研究考察了卢旺达不同条件下农民从事自给自足家庭园艺的决策及其对农户粮食和营养安全的影响。该研究使用了来自卢旺达2012年、2015年和2018年具有全国代表性的数据集。我们采用内生转换回归模型，共同估计家庭园艺参与决策的驱动因素以及粮食和营养安全结果，同时考虑可观察和不可观察因素导致的选择偏差。我们还估计了家庭园艺参与对饮食多样性、食物消费得分以及妇女和儿童人体测量指标的处理效应。处理效应是在样本均值处计算的，并与市场相关变量相关联，如土地所有权、商业化程度和市场距离。我们发现拥有家庭菜园与改善饮食多样性和更好的营养结果相关。如果家庭获得土地的机会有限且居住在离市场较远的地方，收益会更大。相比之下，无论生产商业化程度如何，家庭园艺的收益都是积极且显著的。我们还发现，家庭规模、性别、教育程度、土地获取情况和牲畜所有权是卢旺达家庭园艺参与的统计学显著驱动因素。然而，商业化程度并未影响家庭参与家庭园艺的决策。
