Environmental Impact of Agricultural Land Transfer in China: A Systematic Review on Sustainability

Farmland holding fragmentation facilitates more extensive use of agricultural chemicals, which harm the natural environment. Agricultural land transfer in China aims to consolidate agricultural holdings, promoting economies of scale and addressing socio-economic and environmental concerns. This systematic review aims to examine the impact of agricultural land transfer on the environment. The review evaluates 60 empirical research articles retrieved through the Web of Science and SCOPUS databases, which discuss the relationship between agricultural land transfer and the environment. The findings indicate that agricultural land transfer has both positive and negative impacts on the environment. Farmers who engage in land rental and adopt sustainable agricultural practices, including the utilization of organic fertilizers, implementation of conservation measures, and application of efficient carbon reduction techniques, have demonstrated a notable positive influence on the environment. The lack of regulatory mechanisms concerning agricultural land transfer, including non-adjacent agricultural land transfer and large-scale farmers’ improper chemical utilization, causes significant negative environmental consequences such as biodiversity loss and ecosystem destruction. As such, we recommend innovative institutional developments addressing spatial and temporal considerations, land use, market systems, and household conditions to reconcile the links between agricultural land transfer policy and environmental outcomes. We urge continued research into the multidimensional and potential effects of agricultural land transfer to facilitate better-informed policy-making.
