Spatial optimization of rural settlement relocation by incorporating inter‐village social connections under future policy scenarios

Abstract

Social connections between villages can represent farmers'interests and thus benefit participatory rural relocation planning. With rural development, however, these connections will change and may weaken the adaptation of relocation plans to future rural systems. As yet, most studies still use empirical social connections to guide relocation planning, while a few have incorporated predicted connections in the context of rural development into relocation decisions. Meanwhile, spatial optimization approaches have seldom been adopted to solve this geographical decision issue. Accordingly, our study proposes a novel spatial relocation framework that incorporates changed inter-village social connections under future rural development scenarios. Empirical inter-village connections and their policy-induced changes in central China were explored using social network analysis. An integration of particle swarm optimization and geographic information systems was adopted to identify the relocation solutions with maximum inter-village connections and maximum spatial land use compactness, and to examine how connection changes under different policy scenarios influenced relocation outcomes. The results demonstrate the significance of incorporating policy-induced social connections into relocation plans, and most importantly, show the negative relations between changed social connections | 689 LIU et aL.

The Distribution Levels and Factors Influencing Successful Development of VOE in Trenggalek Regency-Indonesia

“…It is also an effort to increase welfare and prevent inequality jointly. It means it must emphasize the community's interests and be participatory [14]. It was also reported by Muryanti [15] that the ability to cooperate on different issues, especially in the VOE development, can encourage the realization of village independence.…”

Quantitative Analysis and Cause Exploration of Architectural Feature Changes in a Traditional Chinese Village: Lingquan Village, Heyang County, Shaanxi Province

“…As a result, relevant policies and plans have still analyzed economic rationality and technical feasibility from the perspective of planners and managers [39], but they often have not been able to meet the wishes of villagers, resulting in low implementation effects [40]. Therefore, it is crucial to understand the needs and awareness of villagers when making relevant decisions in rural areas [41,42]. On the other hand, in a small number of studies on villagers' awareness and behavior, researchers have only studied the role of psychological factors or villagers' participation in their communities (village committees) in promoting the protection of features.…”

Spatial Coupling Pattern and Driving Forces of Rural Settlements and Arable Land in Alpine Canyon Region of the Maoxian County, China

“…Rural China is in the process of rapid urbanization and modernization, and core factors such as rural settlements and arable land have undergone drastic changes [43]. The existence forms, functional roles, and value behaviors of rural settlements and arable land are also in a critical stage of reconfiguration and transformation [44]; therefore, in the context of rural transformation and development, it is urgent to explore the spatial coupling relationship between rural settlements and arable land to optimize the spatial pattern. The coupling ratio indicates the coupling relationship between the population and arable land in terms of quantity [45].…”
