Sustainable livelihood of farmers is the key to rural revitalization. The purpose of this study was to establish livelihood capital cultivation models suitable for farmers in different agricultural regions and to enhance the sustainability of farmers’ livelihoods by selecting four agricultural regions (suburban agriculture, intensive agriculture, p...

Cultivated land resources are crucial to food security and economic development. Exploring the spatiotemporal pattern of cultivated land non-agriculturalization and its drivers is a prerequisite for cultivated land conservation. This paper used GlobeLand30 data to reveal the spatial and temporal pattern, the shift of the gravity center and the driv...

With the continuous increase in urbanization and non-farm wages, many rural labor forces have transferred to urban areas, significantly changing the population distribution and affecting vegetation restoration and ecological environment improvement. This study analyzed the spatiotemporal patterns of vegetation in Chongqing from 2000 to 2018 based o...

Reasonable rent is the key to promoting land transfer and realizing agricultural operations on a moderate scale in rural China. The purpose of this study was to reveal the spatiotemporal variations in farmland rents and their drivers by employing a multilevel model based on 3547 plot-level transactions in Sichuan Province of China. The results show...

The quantitative evaluation of the suitability of land fallow is of great significance to the effective implementation of fallow system in rural China. The purpose of this study is to systematically evaluate the cultivated areas suitable for fallow in Chongqing, China. The results show that: (1) a comprehensive index of cultivated land fallow (ILF)...

The sustained growth of non-farm wages has led to large-scale migration of rural population to cities in China, especially in mountainous areas. It is of great significance to study the spatial and temporal pattern of population migration mentioned above for guiding population spatial optimization and the effective supply of public services in the...

Given the background of the increasing opportunity cost of farming and the popularization of labour-saving technology, increased fragmentation has gradually become a key factor in the devaluation and abandonment of land assets. To systematically identify the costs of fragmentation, we use a series of indicators such as the number of plots, the Simp...

To clarify the impact of non-agricultural employment on rural land circulation in China, we built logit models using the Chinese Household Income Project 2013 dataset, which includes 18,948 household samples over 15 provinces, 126 cities and 234 counties of China in 2013. We use the proportion of non-agricultural income, the proportion of non-agric...

Under the background of a large population and scarce land resources and the dual structure of land property right, the cultivated land resources in China have been the lifeline of farmers, and their social security function is considered the stabilizer of society. But this view has been increasingly questioned in recent years. The capability of cu...

Land fragmentation and the small size of land parcels are still the major bottlenecks for agriculture sustainable development in rural China, and an efficient land rental market could consolidate land plots and realize agricultural management at a moderate scale. However, transaction cost is still the main obstacle of land transfer. It is, therefor...

Land is the carrier of human activities. All kinds of social and economic problems in the process of urbanization can be reflected in land use. A large number of labor force has been transferred from rural areas especially in mountainous areas to cities, which has changed the population distribution pattern and land use pattern in different time an...

The marginalization phenomenon characterized by devaluation and abandonment of farmland began to appear in mountainous areas. The purpose of this study was to reveal the extent of farmland marginalization and its drivers, and a two-stage tracking survey involving 7045 plots from 1012 households from the southwest mountainous areas of China in 2011...

The lack or instability of the pension system for the elderly in rural China has become a paramount obstacle for sustainable land transfer, namely land use right transfer among farmers, in the context of aging. The New Rural Pension System (NRPS), a pilot project that provided basic security for the elderly, was implemented in 10% of counties in 20...

In recent years, the rent-free farmland transfer has become increasingly prominent in rural China. By employing multiple data sources, this study estimates the extent of rent-free land transfer from 1986 to 2015 and develops a multilevel logit model to identify its drivers. The results show that the extent of rent-free land transfer has been increa...

Facing worsening problems, including the decreasing amount, quality, and deterioration of land ecosystems, cultivated land needs protective measures. China has been conducting an experimental fallow policy to deter these problems in five pilot provinces since 2016. However, inadequate and inconclusive studies of the impacts of fallow policy on food...

Due to the indivisibility of agricultural machinery in production, limited farm sizes have reduced mechanization efficiency and increased the cost of grain production in China. As a result, the development of a moderate-scale farming system has been proposed by academic communities and policy makers. However, it is still hotly debated how to determ...

This paper uses panel data to analyze whether a forest transition has occurred in China and to identify the driving forces behind forest growth in China. We used generalized method of moments (GMM) model to identify forest transition. Analyzing forest transition only at the national level neglects regional differences. The results show that there e...

Land circulation is an important measure that can be utilized to enable agricultural management at a moderate scale. It is therefore imperative to explore spatiotemporal changes in land circulation and the factors that drive these variations in order to maintain and increase the vitality of the land rental market. An initial analysis of spatiotempo...

High transaction costs that have hindered the development of the farmland rental market and lowered the allocation efficiency of farmland resources, especially abandoned or idle farmland, were caused by the incompleteness and instability of farmland property rights. Land titling program that cleared the obstacles of the ambiguous property rights wa...

Since the early 1980s, the multi-cropping index for rice has decreased significantly in main double-cropping rice area in China, which is the primary double-cropping rice (DCR) production area. This decline may bring challenges to food security in China because rice is the staple food for more than 60% of the Chinese population. It has been general...

Land circulation is an important measure that can be utilized to enable agricultural management at a moderate scale. It is imperative to explore spatiotemporal changes in land circulation and the factors that drive these variations in order to increase the vitality of land rental market in China. Based on a sample of 169 511 farm households from th...

Mountainous areas in China account for two-thirds of the total land area. Due to rapid urbanization, rural population emigration in China's mountainous areas is very significant. This raises the question to which degree such population emigration influences the vegetation greenness in these areas. In this study, 9,753 sample areas (each sample meas...

In order to improve the rural labor productivity and farmers' income, land use transfer was launched and encouraged in recent years, especially the Thirteenth Five-Year Plan (2016-2020). This study aims to shed light on the impact of land use rights transfer on household labor productivity, based on a case study of Chongqing in China. Studies have...

A comprehensive set of 30-m resolution land coverage data of 2000 and 2010 was used for an analysis of the spatial heterogeneity of forest area change in early 21st century China. Four regression models were built to determine the current situation of the 'forest transition' in China. The results show that forest area in China has grown rapidly ove...
