Abstract:As environment-friendly recreational facilities, greenways can bring ecological, social, and economic benefits to the residents of agricultural heritage sites (AHS). Zengcheng District of Guangzhou City first implemented the recreational greenway in China in 2008. Liantang Village is the tourist center of the Liantang Spring segment of Zeng River Greenway system. This village has always been an important planting region of black olive and lychee from ancient times, with more than 1800 large old trees until today. Taking Liantang as a case, participant observations, in-depth interviews, and questionnaires (n = 140) are performed to collect relevant data. This study explores the economic and sociocultural influences of greenway implementation on AHS. Findings reveal that greenway tourism and agricultural heritage conservation form a mutually beneficial relationship. The greenway implementation successfully prompts the emergence and rapid development of tourism which significantly improves the economy of the heritage area and effectively increases the income of the villagers in AHS. The sources of their income mainly include agritainment businesses, agricultural product sales, tourist-related business wages, land leases, and house rentals. Most villagers greatly improve their quality of life because of the continuous infrastructure improvements. However, the daily lives and production orders of villagers are disturbed to some extent. The villagers have a highly sober cognition of the value of old trees, and their protection consciousness is enhanced. The difference in the source of economic income affects the judgment of the villagers, and three groups of villagers exhibit some cognitive differences with the influence of tourism. Results indicate that multi-dimensional values of agricultural heritage can be achieved, and a mutually beneficial relationship will then be formed between tourism and agricultural heritage conservation as soon as the correct eco-tourism is developed in AHS.

Sustainable supply chain network design has attracted great attention of academia and industry in recent years. Baijiu is one of the world’s oldest distilled alcoholic beverages and plays a significant role in Chinese culture and Chinese people’s daily life. As the production and consumption of Baijiu have a significant influence on the economic, environmental, and social performance of supply chain management, sustainable supply chain network design decisions are critical to the long-term success of the industry. In concert with the rapidly growing Chinese economy, there is a growing demand for a sustainable Baijiu industry. Therefore, this paper constructs and optimizes a network decision-support model for a sustainable Baijiu industry network design. To achieve this, the Baijiu supply chain is examined and a model is proposed for a design that encompasses economic (costs), environmental (carbon emissions), and social (local employment and regional per capita GDP) dimensions. R language programming is then applied to solve the model. A case example indicated that S1 was the optimal decision for reducing costs, S2 was the optimal solution for minimizing carbon emissions, and S3 was the best for maximizing the social impact. Considering the situation of the Baijiu industry and the focal enterprise, it was concluded that S1 would be the best solution for the case company. And the results verified the effectiveness of the framework. This paper develops a systematic and effective approach that decision-makers can use to conduct sustainable network design for Baijiu enterprises.

Urbanization is one of the major threats to the dynamic inheritance of the agricultural heritage system (AHS). The ability to achieve sustainable development in intra-urban areas is an essential proposition related to the innovation of AHS conservation principles. The Haizhu high bed-low ditch agroecosystem (HHBLDA), a China-Nationally Important Agricultural Heritage System site located at the center of Guangzhou City, is taken as an example in this study. The effect of implementing the Land Acquisition to Keep Agricultural Use (LAKAU) on intra-urban AHS conservation is assessed through literature collection and review, field survey, and in-depth interviews. The results show that the LAKAU was implemented because of a three-decades-long struggle between ecological conservation and urban sprawl. Because of the important functions of ecosystem services, the AHS can coexist with urban land use in the course of rapid urbanization. The LAKAU mode can ensure that the nature of farmland remains unchanged, which is an effective strategy for the conservation of an urban AHS. The resulting problems, such as high operating costs, insufficient agricultural outputs, and insufficient local farmers in the AHS site because of off-farm opportunities, should be addressed by establishing an effective self-sustaining mechanism. Realizing the compatibility of management concepts between the AHS and nature reserves, adapting to the changing role of farmers, and strengthening the acceptance of the AHS by urban managers should attract the attention of decision-makers.
