Most farmers in Nigeria are food-insecure smallholders without secure land tenure. Children growing up in these households may be at higher risk of malnutrition. However, there is a paucity of evidence of the effect of land tenure on child nutrition. The present paper examines whether smallholders' mode of land acquisition and tenure documentation could influence child malnutrition in Nigeria. The paper relied on the three-round Nigerian nationally representative panel data of smallholder farming households with small children. The World Health Organisation's standards were used to determine child anthropometric deficits such as stunting, wasting, underweight, overweight and stunted-overweight. The study analysed the effect of smallholders' mode of land acquisition and tenure documentation on child malnutrition using the flexible panel difference-in-difference (flexpaneldid) model and fixed effect (FE) logistic regression. Households on family-inherited land were more likely to have stunted, underweight and overweight children. However, households that held community-distributed land were less likely to have stunted, overweight and underweight children. While the formal land certificate holders had a 13% chance of having stunted children, the informal land document holders were seven percent and five percent less likely to have wasted and underweight children. Smallholder land tenure had a small but relevant effect on reducing child malnutrition with community-level land distribution and informal land documents in Nigeria.

尼日利亚的大多数农民都是粮食不安全的小农，没有安全的土地使用权。在这些家庭长大的儿童可能面临更高的营养不良风险。然而，缺乏土地保有权对儿童营养影响的证据。本文研究了小农的土地征用方式和土地使用权文件是否会影响尼日利亚的儿童营养不良。该论文依赖于三轮尼日利亚全国代表有小孩的小农户的面板数据。世界卫生组织的标准用于确定儿童的人体测量缺陷，例如发育迟缓、消瘦、体重不足、超重和发育迟缓超重。该研究分析了小农户的影响flexpaneldid ) 模型和固定效应 (FE) 逻辑回归。家庭继承土地上的家庭更有可能有发育迟缓、体重不足和超重的孩子。然而，拥有社区分配土地的家庭不太可能有发育迟缓、超重和体重不足的儿童。虽然正式的土地证持有者有 13% 的机会有发育迟缓的孩子，但非正式的土地证持有者有 7% 和 5% 的可能性降低了孩子消瘦和体重不足的可能性。在尼日利亚，小农土地使用权通过社区层面的土地分配和非正式土地文件对减少儿童营养不良产生了微小但相关的影响。
