“…The fragmentation of farmland and the scattered settlement reflect the fact that rural life in mountainous areas has also exacerbated the organizational dilemma of manpower, resources, and capital in the revitalization of rural industries [30,36], resulting in damage to the regional functions of rural areas. Fragmentation of land use has strong externalities and requires effective collective action among farmers to internalize the externalities of agricultural land use into the benefit of the organization [37].…”

China is facing an important period of rural governance innovation and restructuring of territorial spatial patterns. This paper selects catchments as the most closely related spatial units for rural industrial development and rural settlement activities, profoundly revealing the characteristics of transformational development and spatial governance in mountainous areas. To date, extensive literature in this area has produced a broad multidisciplinary consensus on catchment water and soil conservation and rural industry development; however, the interactive mechanism of ecological, social, and economic networks, and the characteristics behind small catchments which benefit from spatial governance, have never been analyzed and are relatively new to the sphere of rural governance. Our research argues the relative importance of multi-scale catchment units compared with traditional administrative village units in enhancing the organizational benefits of rural revitalization in terms of workforce, resources, and capital, using the case study of a catchment in the Wuling mountainous area. Our study presents a framework to explore the multi-dimensional governance experience of a small catchment in the Wuling mountainous area and proposes to integrate the resource endowment advantages of small catchments into rural industries development and transform the economic and social benefits contained in the ecological environment into multi-scale spatial benefits among farmers, villages, and the regional rural area. However, not all cases provide positive evidence. The overall development of a catchment is confronted with complex constraints, which are mainly related to the development stage and local historical and geographical factors. Furthermore, affected by the top-down “project-system” in the “poverty era”, the logic of “betting on the strong” and the single-centered logic of resource allocation at the grassroots level exacerbated the fragmentation of the mountainous area. Generally speaking, the catchment perspective promotes regional linkage development and multi-center governance modes and triggers multidisciplinary theoretical thinking to some extent. The catchment’s overall development helps play to the comparative advantage of mountainous areas and promotes endogenous sustainable development to a certain degree. However, the promotion of catchment governance in poverty-stricken mountainous areas is faced with a lack of financial foundation and needs support in order to break through the national system and local social constraints.

“…Hence, the K-nearest neighbors method was chosen. Some researchers have reported that little attention has been paid to the effects of the K-nearest neighbor spatial distribution, utilization, and natural properties of cultivated land resources based on fragmentation, especially in the context of spatial scales (Ciaian et al 2018;Liu et al 2019). Thus, the bivariate spatial autocorrelation was introduced to analyze the degree of matching of cultivated land fragmentation with the natural or social environment.…”

“…Cultivated land fragmentation is a common feature in both transition economies and developing countries (Liu et al 2019). Some studies have defined the fragmentation of cultivated land through multiple strategies: (1) dividing the land based on the same or different ownership; (2) distinguishing between use rights and ownership; (3) considering the utilization type and structure of adjacent cultivated land as the basis for fragmentation; and (4) considering the number, size, shape, and distribution of patches and the distance between patches (Ntihinyurwa et al 2019; Postek, Leń, and Stręk 2019).…”

“…This is because more gross changes might only result in a limited net change while being associated with a much larger change in the landscape pattern (Yu et al 2018). Furthermore, some studies have combined the factors that drive the occurrence of cultivated land fragmentation or its impact (i.e., socioeconomic policies, agricultural policies, and the natural environment) (Cheng et al 2015;Ciaian et al 2018;Falco et al 2010;Liu et al 2019;Tan, Heerink, and Qu 2006) to explore strategies for coping with cultivated land fragmentation such as ownership interchange or land consolidation. Nonetheless, several remaining shortcomings must be addressed.…”

“…Second, cultivated land fragmentation caused by the long-term effects of socioeconomic systems and the natural environment must be assessed on a long time series (Ciaian et al 2018;Liu et al 2019). Third, most previous research on cultivated land fragmentation has primarily been conducted at household (Tran and Vu 2019), regional (Ciaian et al 2018;Liu et al 2019), farm (Ntihinyurwa et al 2019), county (Chen et al 2016), and watershed (Su et al 2014) scales. Such studies require the identification of the areas of cultivated land fragmentation to implement land consolidation and to reflect the internal regional changes.…”

Assessing the temporal and spatial characteristics of cultivated land fragmentation is necessary to identify management practices that can reduce negative environmental effects. Thus, the purpose of this study was to use principal component analysis and spatial autocorrelation to analyze the dynamic characteristics of cultivated land fragmentation in different landform areas in Liaoning Province, China, in terms of time and space. An additional objective was to match the changes with the natural and social environment to support the sustainable development of fragmented cultivated land. The results indicated that the evolutionary trends of cultivated land fragmentation in the central plain area showed a weakening trend, contrary to those observed in the western hilly and eastern mountainous areas. Moreover, the spatial distribution characteristics of cultivated land fragmentation in the western hilly area were generally "external low, internal high," primarily because of the edge density of cultivated land patches. The spatial distribution characteristics of cultivated land fragmentation in the central plain area were generally "external high, internal low," primarily because of the number and division of cultivated land patches. The spatial distribution characteristics of cultivated land fragmentation in the eastern mountainous area were generally "south low, north high" because of the division of cultivated land patches. These results can provide guidelines for planners, managers, decision-makers and others to formulate regulatory policies, identify land remediation areas, and promote the sustainable development of cultivated land.

Classification of agricultural land consolidation types based on soil security to improve limiting factors adapted to local soil conditions

et al. 2023

Agricultural land consolidation (ALC) is an effective tool to ensure national food security. The current ALC is a government‐led systematic behavior with regional characteristics, most ALC types are classified according to difficulty without considering the safety of soil systems, resulting in randomness in the site selection of projects. Given the soil complexity, ensuring soil security (SS) is a prerequisite for efficiently completing ALC. ALC that gives full play to the soil's functional advantages is an effective means of securing SS. The main goal of this study is to establish a new set of technical processes for classifying the types of ALC from the perspective of SS, including the agricultural SS evaluation system and the identification method of land‐improvable limiting factors. We used a generalized mean model to evaluate and analyze SS in multiple dimensions and identified 11 combinations of limiting factors in Wen County through the k‐means clustering method. The combination of the limiting factor clustering area with the SS spatial distribution patterns guided five ALC types. When compared using the spatial pattern comparison method, the new ALC guideline avoids the singularity of ALC types, selects the field patch as the evaluation and decision‐making unit, and improves the accuracy of land management measures. The results indicate that incorporating SS into ALC policy planning and decision‐making can provide complex and multifaceted knowledge of factors affecting SS, and potential solutions to make agricultural soils safer, enabling higher quality and sustainability of agricultural land use.
