Abstract: We examine the role of soil conservation practices (SCPs) in promoting sustainable agri‐food production to achieve food and nutrition security. To this end, we use the endogenous treatment regression model, as it allows us to address the selection bias associated with SCP adoption. Data sourced from the 2020 China Land Economic Survey, collected by Nanjing Agricultural University, China, are examined. First, we analyse the association between the adoption of SCPs and rice yield; we focus on rice as it is the most common staple food globally. Then, we examine the links between SCP adoption and dietary diversity and the consumption of seven specific foods (rice, potato, pork, poultry, egg, fruits and vegetable oil). This allows us to glean insights into how SCPs may affect the dietary patterns in rural communities. The findings show that adopting SCPs is associated with an 8.5% increase in rice yield. Rice yields increase with the intensification of SCP adoption. Disaggregated analysis suggests that low‐income farmers receive the most rice yield promotion by adopting SCPs compared with wealthier ones. Meanwhile, among the three SCPs (i.e. soil remediation, commercial organic fertiliser application and formulated fertilisation) considered in our study, only formulated fertilisation increases rice yields. Furthermore, adopting SCPs is associated with higher consumption of protein‐rich foods and lower dietary diversity.
