“…However, labor‐demanding practices are less attractive to farmers, because wages increase with the ongoing economic development. Although the Chinese government has gradually implemented policies to protect market grain prices, the price of agricultural products is still regulated through policies, which hinders the farmers’ enthusiasm for agricultural investment and the application of new technology (Song, Han, & Deng, ). Therefore, we suggest future research on agronomic management strategies should consider including how to improve nutrient efficiency and simplify crop management practices.…”

Climate variability has resulted in mismatches between recommended and optimum seeding rates, sowing and harvest dates, fertilizer application, and irrigation levels in North China Plain double cropped systems. The objective of this study was to compare traditional local double-crop practices (LP) with high-yield double-cropped treatments (HY) and precision double-cropped managements (PM). The LP treatment follows local practices, whereas HY optimizes yield regardless of cost, and PM optimizes economic returns by adjusting the planting and harvest dates, and the seeding and fertilizing rates. The average production cost for LP, HY, and PM was 3775, 4824, and 4218 USD ha −1 , respectively, and the average income was 5882, 6892, and 6622 USD ha −1 . The annual yield for the PM was 3.9% lower, and the annual profit was 16.2% higher than those for HY. The annual yield for the PM was 11.8% higher, and the annual profit was 11.0% higher than those for the LP. Unlike LP, HY and PM transferred 1.19-2.52% of the redundant effective accumulated temperature and the cumulative solar radiation received during the wheat (Triticum aestivum L.) season to the maize (Zea mays L.) season. This increased the production efficiency attributed to temperature and light energy by 12.86-17.48%. In addition, PM obtained the greatest N use efficiency among all treatments. These results show that PM is the appropriate approach to simultaneously increase yields, resource efficiency, and profit. The findings can be used to provide a scientific basis for double-crop wheat and maize systems featuring high yield and high efficiency.

“…In terms of grain production, changes in government policy have also had a significant impact, with price subsidies reduced in the 1990s, incentives offered for growing improved varieties and adopting modern machinery, and deregulation of grain marketing. These measures have stimulated increased production from the early 2000s, especially after rural tax reforms in 2002/3 [10]. This can be seen in Majia, where grain yield has risen on terms of output per unit of labor.…”

“…The focus here is upon the survival of farmland in the fringe and its transformation under the influence of large-scale urban expansion and rural-urban migration. It is argued that whilst there have been certain China-specific characteristics that reflect the scale and pace of change, as well as the impact of policy interventions [10], there are also changes comparable with similar developments in the West. Hence, the specificities of the local situation have been tempered by the impacts of global phenomena.…”

Rapid urbanization in the past four decades has transformed the hinterlands of China’s major cities. While urban growth has consumed large quantities of farmland, many of the remaining farms in the country’s peri-urban fringes have responded to the nearby presence of a fast-expanding and wealthier urban market by changing the farm enterprise to cater directly for this market. The various responses are exemplified herewith, for the metropolis of Xi’an-Xianyang (13 million population), in north-west China’s Shaanxi Province. Based on participant observation and structured interviews with a sample of farmers from three peri-urban fringe villages, the study charted changes in ecosystem services as a quantitative measure of change between 1986 and 2017. An additional Delphi approach focused on the chief technological innovations during this period. The survey revealed the growing multi-functionality of those villages that had switched from traditional grain production to horticulture, supported by various government-funded programs. A significant development has been the introduction of farm-based tourism catering for urban-based tourists. The physical appearance of the fringe now resembles the so-called desakota landscape associated with south-east Asian cities, as massive new urban-industrial complexes sit alongside villages amidst islands of intensive farmland. The conclusion addresses key issues regarding the overall sustainability of agriculture within this fast-changing process of rapid urbanization.

“…The spatial distribution of both farmland and labor force directly affects the spatial pattern of the GPS [73]. Technology forms the core element of the modern GPS and its spatial distribution features directly affect the production technology system and level of modernization [74]. In addition, the role of capital in grain production is constantly strengthened [75], because the spatial difference between spread and flow of capital determines the degree of marketing of grain production in different regions [76].…”

China's grain production has transformed from absolute shortage to a current structural oversupply. High-intensity production introduced further challenges for the eco-environment, smallholder livelihood, and the man-land interrelationship. Driven by urban-rural transformation, research on food security patterns and grain production has expanded into a new field. To analyze the challenges and required countermeasures for China's grain production system (GPS), this study constructed a theoretical GPS framework based on space resilience. Firstly, a new GPS concept was proposed and a functional system was established for protecting the regional food security, thus guaranteeing smallholder livelihood, stabilizing urban-rural transformation, and sustaining the eco-environment in terms of economic, social, and ecological attributes of the GPS. Secondly, based on a cross-scale interaction analysis that varied from a smallholder scale to a global scale, the systematic crisis of the GPS was analyzed. Thirdly, a cross-scale analytic framework of the GPS was formed from the perspective of spatial resilience, integrating both inner and external disturbance factors of the GPS. Both spatial heterogeneity and connectivity of internal and external disturbance factors are important contents of system space resilience. Finally, the hierarchy of spatial resilience of GPS became clear. The transformation of labor force and the land use transition form key thresholds of the GPS. In summary: based on protecting the basic functions of the GPS, the cross-scale effect of systematic disturbance factors and relevant countermeasures for spatial resilience are effectively influenced by the coordination of the interests of multiple stakeholders; spatial resilience is an effective analytical tool for GPS regulation, providing a reference for revealing the inherent mechanism and functional evolution of the GPS in the process of urban-rural transformation.
