Home gardens have been an integral part of the recent food-based interventions aimed at stimulating changes in dietary patterns and improving nutrition. However, evidence of their effects on food security, dietary quality, child anthropometry and incomes is limited, particularly among vulnerable populations groups. Using panel data from a sample of approximately 1900 households from vulnerable population groups in Odisha, India, difference-in-differences and other econometric techniques, we analyse the effects of home gardens on food security, dietary quality, child anthropometry and income. On average, home gardens contribute to better household food security, higher dietary quality of men and women but do not contribute to higher children's dietary quality and anthropometry. Also, home gardens increase monthly per adult equivalent incomes by 37% and reduce the prevalence of poverty by 11.7 percentage points. Quantile regression results suggest that home gardens enhance food security and incomes in all quantiles, but richer farmers benefit more than poorer farmers. Overall, home gardens can enhance household food security, dietary quality of men and women, and income gains among vulnerable farming population groups, but they may not suffice to improve child dietary quality and anthropometry.

印度奥里萨邦农村农户的家庭花园、家庭营养和收入

家庭花园已成为最近以食物为基础的干预措施的一个组成部分，旨在刺激饮食模式的改变和改善营养。然而，它们对粮食安全、膳食质量、儿童人体测量和收入的影响的证据有限，特别是在弱势群体中。我们利用印度奥里萨邦弱势群体约 1900 个家庭的面板数据、双重差分法和其他计量经济学技术，分析了家庭花园对粮食安全、膳食质量、儿童人体测量和收入的影响。平均而言，家庭花园有助于改善家庭粮食安全、提高男性和女性的饮食质量，但无助于提高儿童的饮食质量和人体测量学。还，家庭花园使每个成年人的每月同等收入增加 37%，并使贫困发生率降低 11.7 个百分点。分位数回归结果表明，家庭菜园可以提高所有分位数的粮食安全和收入，但较富裕的农民比较贫穷的农民受益更多。总体而言，家庭花园可以提高家庭粮食安全、男性和女性的饮食质量以及弱势农业人口群体的收入增长，但可能不足以改善儿童饮食质量和人体测量。
