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. [ABSTRACT FROM AUTHOR]

Revolutionary agricultural structural reforms in the supply chain and cutting-edge institutional mechanisms are pivotal in catalyzing a quantum leap in food production. China’s focus on achieving self-sufficiency in grain production for domestic security necessitates structural reforms in the agricultural supply chain and innovative institutional mechanisms. The emergence of socialized agricultural institutions plays a pivotal role in providing essential services to smallholder farmers. However, a dearth of studies evaluating the efficacy of these services in enhancing grain production exists. This study aims to fill this gap by analyzing provincial panel data from China spanning 2011 to 2020 to evaluate the impact of Agricultural Socialized Services (ASS) development levels on grain production. Employing panel and panel threshold models for empirical analysis, the research investigates how this impact varies between major grain-producing regions and non-major grain-producing regions. Findings indicate a significant positive effect of ASS on grain production, with a correlation coefficient of 1.3555. While its impact is less pronounced in grain-producing regions, it proves beneficial in non-grain regions. Moreover, the transfer of farmland use rights amplifies ASS’s influence on grain production, with a threshold value of 33.18%. The study concludes by outlining policy implications from various perspectives, providing practical recommendations for policymakers and stakeholders in the agricultural sector. [ABSTRACT FROM AUTHOR]
