The Food and Agriculture Organization of the United Nations (FAO) launched the conservation initiative of the Globally Important Agricultural Heritage Systems (GIAHS) in 2002, providing a new solution to current global problems such as widening gap between rich and poor, environmental pollution, biodiversity destruction and degradation of agro-ecological functions. However, since the implementation of GIAHS, few studies have evaluated the role of GIAHS in regional sustainable development. To fill this research gap, this paper attempts to build an evaluation index system that integrates economic, social and environmental sustainability by matching the 169 subgoals and 232 indices of the UN Sustainable Development Goals (SDGs) with five FAO-GIAHS selection criteria and selecting the indices. The index weights are determined through Delphi method (expert scoring) and Analytic Hierarchy Process (AHP). Then the GIAHS site of the Kuaijishan Ancient Chinese Torreya Community in Shaoxing City, Zhejiang Province is taken as an example for evaluation to enhance the empirical study. The results show that the comprehensive score for this heritage site is 77.90 points, of which economic, social and environmental sustainability scores 88.27, 86.12 and 69.71 points respectively, showing a descending trend. Thus, ecological protection of the Kuaijishan Ancient Chinese Torreya Community should be strengthened and be given prominence in the future. As for the contribution to further research, this SDGs-based GIAHS sustainability evaluation framework can serve as an important guide for assessing the approaches and effects of GIAHS in promoting the achievement of the SDGs. It can also be used for future international GIAHS sustainability assessment and comparison and provide a basis for adjusting the development model of GIAHS sites.

The development and adoption of agriculture has been investigated for decades, and remains a central topic within archaeology. However, most previous studies focus on the crop’s domestication centers, leading to gaps in knowledge, particularly in transitional zones between these centers. This paper reviews published archaeobotanical evidence and historical documents to reconstruct the trajectory of agricultural systems in Holocene Jiangsu Province. Comparing these new results to paleoclimate information, historical documents, and archaeological data enables us to better understand the underlying influences of past agricultural development. Our results indicate that a warm and wet climate may have promoted ancient peoples to first settle in Jiangsu between 8,500 and 6,000 BP and adopt rice farming. The continuous warm and wet climate may have facilitated the rapid development and expansion of rice agriculture, ultimately contributing to large-scale human settlement in 6,000–4,000 BP in Jiangsu Province. Between 4,000 and 2,300 BP during a cooler and drier climate millet agriculture diffused southward, facilitating a mixed rice and millet agricultural system. This mixed farming supported a continuesd widespread settlement and population growth in Jiangsu. After 2,300 BP, political instability in north China resulted in further southeastward migration, advanced planting technology was brought about to south China, facilitating highly developed agricultural systems and rapid population expansion in Jiangsu. Population growth led to the establishment of Jiangnan as the regional economic center, where people chose high-yielding rice and wheat rather than millet.

The effective participation of peasants can raise the quality of high-standard farmland construction (HSFC) in China. How to avoid inefficient participation is an urgent issue that needs to be solved in the field of HSFC. However, the factors that influence peasants’ effective participation in the HSFC remains to be further studied. This study used factor analysis and a comprehensive evaluation method to calculate social networks and the level of peasants’ effective participation in HSFC based on a survey dataset of 347 peasants in Yancheng City, China. The influence of information support, incentive support, constraint support, network interaction, network trust, and network norms on the level of peasants’ effective participation in HSFC was analyzed using an ordered logistic model. The results of the study indicate that: (1) The overall level of peasants’ effective participation in the HSFC is at a “medium” level, and the level of peasants’ effective participation needs to be further raised. (2) Government support considerably influences peasants’ effective participation in HSFC. Information support, incentive support, and constraint support significantly impact peasants’ effective participation in HSFC. (3) Social networks possess a significant positive impact on the level of peasants’ effective participation in HSFC, with the core variables contributing to peasants’ effective participation in the order of network interaction, network trust, and network norms. (4) Peasants’ cognition significantly impacts peasants’ effective participation in HSFC. Therefore, to enhance the level of peasants’ effective participation in HSFC, it is suggested to further improve government information support, incentive support, and constraint support; strengthen network interaction, enhance network trust, improve network norms, and effectively play the role of social networks; and to strengthen peasants’ education and training.

Synergizing agricultural heritage conservation with tourism utilization is pivotal for sustainable regional development. Using a difference-in-differences (DID) method and entropy weight method (EWM), this study comparatively analyzed the economic resilience of two UNESCO agricultural heritage sites in China: the Wujiang Silk Culture System and the Longji Terraces in Longsheng, from 2019 to 2023. The results revealed that heritage certification significantly promotes tourism growth, increasing revenue in Wujiang by 12.5% and visitor numbers in Longsheng by 18.3%. However, the resilience mechanisms varied distinctly between the sites: Wujiang displayed a market-driven resilience pattern characterized by effective cultural tourism integration, whereas Longsheng remained vulnerable due to resource dependency and infrastructural constraints. Further, Wujiang’s robust policy framework involving heritage conservation, tourism development, and ecological compensation fostered sustained resilience, albeit facing long-term challenges such as potential cultural commodification. This research contributes theoretically by quantifying the resilience disparities via spatial econometric analyses, identifying market-institution drivers, and proposing a “Four-Dimensional Optimization Matrix”, integrating value activation, infrastructure enhancement, industrial symbiosis, and adaptive governance. Practically, it provides tailored policy insights for improving resilience, avoiding over-commercialization, and promoting sustainable tourism practices applicable globally, particularly in developing economies managing heritage sites.

Agriculture is a critical foundation for the development of large-scale complex and urban societies. Sanxingdui, located on the Chengdu Plain in western Sichuan and linked with the ancient Chinese Shu Kingdom, is one of the most distinctive archaeological sites in the world. However, despite its importance, the agricultural economy of the Sanxingdui culture and the Chengdu Plain remains poorly understood and heavily debated. This study synthesizes recent archaeological and historical evidence concerning the agricultural economy underpinning the increasing scale and social complexity at Sanxingdui and the greater Chengdu Plain prior to 2200 BP. Our analysis finds a mixed rice and dry-land millet farming economy, in conjunction with pig and chicken husbandry, during the Sanxingdui culture (3700–3100 BP). This integrated agricultural system likely began with the Baodun culture (4500–3700 BP), passing to the Sanxingdui culture (3700–3100 BP), Shierqiao culture (3100–2600 BP) and later, the Shu culture (2600–2300 BP). In addition, although gathering, hunting, and fishing accounted for relatively low proportions of the overall subsistence, the ancient peoples at Sanxingdui and across the Chengdu Plain continued these practices, supporting a diverse agricultural and food system. Understanding the subsistence at Sanxingdui offers key insights into the development of complex societies in southwest China, the contributions to Chinese culture, and the role of agriculture worldwide.

The study examines the influence of the urban spatial structure on smog pollution and its mechanism of action using the panel data of Chinese cities from 2012 to 2017. Research suggests that the multi-center development of Chinese cities has aggravated regional smog pollution. Robustness test results support this finding. Results of the interaction term shed light on the fact that multi-center spatial development in backward regions can exert a greater influence on smog pollution. Meanwhile, suppose the research samples are divided by different zones. In that case, it can be observed that an inverted-U shape characterizes the multi-center development of regions of East China and smog pollution. This indicates that worsening smog pollution appears only as a periodical phenomenon of the pre-stage multi-center development of Chinese cities, which can be ushered into a turning point through certain paths. Analysis of the influence mechanism shows that the transport mode and the energy consumption intensity constitute two major channels for multi-center development of Chinese cities to affect regional smog pollution.
