Smallholder farmers play a crucial role in global agricultural development. The digital transformation of smallholder agriculture can enhance productivity, increase farmers’ income, ensure food security, and promote sustainable rural development. However, existing studies often fail to analyze the holistic nature of this transformation and lack a systematic review of the relevant literature. Therefore, this study aims to provide a comprehensive presentation of the current studies on the digital transformation of smallholder agriculture through logical synthesis and reflective summarization, thereby offering valuable academic insights and practical guidance for the digital transformation of smallholder farming. This study constructs an analytical framework centered on “government–technology–smallholders” using a literature review methodology, systematically examining the main practices, challenges, and future strategies for the digital transformation of smallholder agriculture. Our review reveals that current practices primarily focus on digital agricultural production, rural e-commerce, and agricultural information exchange. We identify key challenges at the government, technical, and smallholder levels, including inadequate digital agriculture policies, limited availability of digital applications, difficulties in adapting uniform technologies to the diverse contexts of smallholders, insufficient resources and endowment among smallholder farmers, significant group disparities, and constraints imposed by social and cultural factors. To enhance the digital transformation of smallholder agriculture, it is essential to improve the supply of policy resources, increase attention to and responsiveness toward smallholder needs, and refine digital governance policies. Additionally, we must develop user-friendly digital applications that cater to the varied digital needs of farmers, reduce access costs, enhance digital literacy, foster an inclusive environment for digital agricultural development, and respect and integrate the social and cultural contexts of smallholder communities. This study deepens the understanding of digital transformation in smallholder agriculture and provides theoretical insights and practical guidance for policymakers, technology developers, and smallholder communities. It contributes to sustainable agricultural development and supports rural revitalization and shared prosperity.

The regulation of pesticide operations still faces numerous challenges and issues. Conflicts of interest and power struggles among the government, pesticide operators, and farmers are crucial factors that impact the effectiveness of regulation. To enhance efficiency and ensure the quality and safety of agricultural products through stakeholder cooperation, this paper presents a dynamic evolution model based on the theory of evolutionary games. The model incorporates the government, pesticide operators, and farmers and evaluates the stability and effectiveness of the stakeholder cooperation mechanism under different circumstances. The research findings indicate the following: The relationships between the government, pesticide-operating enterprises, and farmers are characterized by intricate dynamics of cooperation and competition, coordination and contradiction, reciprocity, and mutual detriment. The stability and effectiveness of the stakeholder cooperation mechanism vary depending on different parameters. Several factors influence the stability of the stakeholder cooperation mechanism, with regulatory supervision from the government, stringent penalties for non-compliant pesticide operations, and strong incentives for farmers’ oversight being the most significant. The stakeholder cooperation mechanism can establish an evolutionary stabilization strategy when these factors reach a certain threshold. This study contributes to understanding the operational mechanisms of stakeholder cooperation in pesticide operation regulation and offers decision support and policy recommendations to relevant stakeholders for advancing the sustainable development and optimization of pesticide operation regulation.

The Pearl River Delta (PRD) is a highly urbanized region in China that faces significant challenges in land use management. These challenges include the decrease in agricultural and ecological land resulting from rapid urbanization, the effectiveness of government governance, and the trajectory of development, all of which warrant careful research examination. Moreover, existing studies on land use in the PRD predominantly rely on static historical analysis, lacking a multi-scenario simulation approach. This study examines land use in PRD using a Patch-Generating Simulation (PLUS), from 1985 to 2020 to address this gap. Three scenarios were established to simulate potential land use outcomes in the PRD by 2030: spontaneous change, cropland protection, and ecological protection. The findings reveal that cropland, forest, and impervious surfaces are the dominant land use types in the PRD. From 1985 to 2020, the proportion of cropland decreased from 37.63% to 27.40%, with most conversions occurring to impervious surfaces and forest land. The proportion of impervious surfaces increased from 1.81% to 12.57%, primarily from conversions of cropland, forest, and water bodies. Economic development, population growth, accessibility, climatic factors, and topographic conditions were shown to be the primary determinants of land use in the PRD. Modelling results suggest that under the spontaneous change scenario, cropland and ecological land decrease, while impervious surfaces expand significantly, threatening cropland preservation and ecological construction. However, under the cropland protection scenario, the conversion rate of cropland to other land types can be effectively controlled, contributing to efficient preservation. Under the ecological protection scenario, impervious infrastructure encroachment on ecological land can be mitigated, but cropland protection is limited. The study proposes cropland protection and ecological priority policies to optimize the structure of land use, enhance efficiency, and offer policy guidance for the efficient utilization of land resources and the preservation of the ecological environment in the PRD.
