“…Improving the ECLU has become an important part of ensuring food security and solving environmental pollution problems. Scholars have focused on research related to ECLU, including land fragmentation, land scale management, labor transfer, and digital inclusive finance [68][69][70][71].However, it is worth noting that currently, only a few scholars have included environmental pollution in the evaluation indicators of farmland utilization efficiency. Scholars mainly focus on agricultural non-point source pollution or agricultural carbon emissions in terms of unexpected output related to environmental pollution.…”

Agricultural productive services are fundamental in transforming the paradigm of agricultural development and exert a significant impact on farmers' behavior in managing their arable land. This paper employs the slack-based measure of the super-efficiency model, known as the Super-SBM model, incorporating unexpected output to gauge the eco-efficiency of cultivated land use (ECLU). Utilizing panel data from Hunan Province spanning the years 2007 to 2020, this study unveils the following key findings: (1) Across various quantile levels, agricultural productive services exhibit a substantial capacity to enhance ECLU, with coefficients ranging from 0.070 to 0.156. (2) The impact of agricultural productive services on ECLU is constrained by both farmers' income levels and the scale of cultivated land, revealing a dual threshold effect. As income levels rise, the corresponding coefficient increases progressively, from 0.0771 to 0.1147, and ultimately to 0.1571. Similarly, with the expansion of cultivated land, the coefficient increases from 0.1152 to 0.1443, and ultimately peaks at 0.1694. (3) The enhancement of ECLU through agricultural productive services is achieved by reducing the input of environmental factors and mitigating undesirable outputs. (4) Agricultural productive services indirectly facilitate labor transfer, accounting for 10.8% of the overall effect. Consequently, it is imperative to continually enhance the agricultural socialized service system, bolster financial support, and implement policies that foster the development of agricultural productive services to realize sustainable cultivated land utilization.

“…For farmers, the shape of farmland patches affects their utilization. Studies have shown that farmers are not keen to invest in modern agricultural technologies when the patches become small or irregularly (Di Falco et al, 2010;Tan et al, 2010;Hou et al, 2021).…”

Spatio-temporal patterns and driving mechanism of farmland fragmentation in the Huang-Huai-Hai Plain

Exploring the spatio-temporal variations of farmland landscape patterns in a traditional agricultural region can provide scientific support for decision-making on sustainable rural land use and rural vitalization development. This study established a comprehensive evaluation index for farmland fragmentation with multiple aspects (dominance, integrity, aggregation, regularity, and connectivity) at the county scale. The goal was to identify the evolution of farmland fragmentation in the traditional agricultural region of the Huang-Huai-Hai Plain during 2000-2015 and investigate underlying drivers using panel data of 359 counties. Results showed an accelerating but fluctuating fragmentation pattern of the farmland landscape. The indexes of dominance, integrity, and aggregation of farmland decreased most sharply, while the index of connectivity increased. Furthermore, the evolution of the farmland fragmentation pattern showed significant spatio-temporal heterogeneity, which is similar to the trajectory of urbanization and land use transition. Farmland fragmentation in municipal districts also emerged earlier and was more severe than in county-level cities and counties. Factors influenced by advancing urbanization include the proportion of artificial land, population density, and proportion of primary industry; these factors drove the evolution of farmland fragmentation. In contrast, the increase in income of rural residents and production efficiency of farmland were the key factors contributing to the improvement in farmland connectivity.

“…Farmland fragmentation, on the one hand, is conducive to enhancing the technical efficiency of agricultural production, lowering agricultural production risks, and increasing farmer incomes (Niroula & Thapa, 2007; Ntihinyurwa et al, 2019; Tran & Vu, 2019; Yu et al, 2022). On the other hand, due to high fixed costs, lots of technological innovations, ways to transfer knowledge to farmers, and modern management practices have lower efficiency (Hou et al, 2021; Wu et al, 2018). Added to that, some scholars pointed out that farmland fragmentation has a threshold effect on agricultural ecological efficiency (Cao et al, 2020; Hartvigsen, 2014; Hou et al, 2021), and it is believed that moderate large‐scale agricultural operation driven by land consolidation is viewed as an effective way to solve this issue (Janus & Ertunç, 2020; Liu & Li, 2017a, 2017b; Long, 2014).…”

“…The comprehensive index method can comprehensively depict the overall features of farmland fragmentation (Liu, Jin, et al, 2019; Liu, Liu, et al, 2019). Regarding the research scale, the macroscale is based on land use status and remote sensing data to measure the fragmentation status based on grids (Hou et al, 2021; Jiang et al, 2021). From the mesoscale perspective, survey data of villages are applied to delve into the fragmentation consolidation mode (Di Falco et al, 2010; Tan et al, 2008).…”

A multidimensional assessment and analysis of farmland fragmentation in the southeast coastal area of China

Farmland fragmentation is a typical feature of arable land use in the economies dominated by smallholder production mode, and scientific evaluation of farmland fragmentation is an effective and crucial process to find and solve problems. Farmland fragmentation, as a kind of long‐standing physiographic landscape and agricultural economic phenomenon under the comprehensive effect of “human‐land‐property rights”, not only contains the scale status and spatial distribution of cultivated patches but also is featured with farming and tenure right. However, the theoretical interpretation of the multidimensional characteristics of farmland fragmentation was insufficient, and it was rare to evaluate the farmland fragmentation based on plot scale. To this end, an evaluation framework of farmland fragmentation with four dimensions and 12 indicators was constructed in this paper. Moreover, regarding Minqing County located in China's southeast coast as a case, empirical research was thus conducted. The findings indicated that the physical properties of farmland patches were depicted through scale fragmentation. Spatial fragmentation represented the spatial distribution of farmland patches. Farming fragmentation revealed agricultural production and management differences while tenure fragmentation embodied the tenure rights segmentation induced by the land distribution system. Farmland fragmentation consolidation was an effective way to solve these issues, and some differential tactics should be conducted in accordance with the path of “zoning types–obstacle factors–consolidation directions–treatment measures”.
