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 multiple problems of modern agriculture urge people to probe into sustainability of the traditional agriculture. As important representatives of Chinese traditional agriculture, the agricultural heritage systems on aquatic-ecological conservation (AHSAEC) are confronting threats and urgently needs to be protected. In this study, the functions and value of the AHSAECs are analyzed by multi-disciplinary methods including system analysis methods based on the review of old books and modern scientific research literature, and the nature of their sustainability are discussed, and the countermeasures against their current unsustainability are proposed. The results show that AHSAECs derive from the simple eco-agriculture models such as the Taihu Lake multi-industry compound ecoagriculture model in historical periods. These systems can integrate farming, forestry, animal husbandry, and aquaculture and make them a sustainable recycling system. Thus, they have strong ecological stability, rich cultural connotation, and good comprehensive benefits. Traditional eco-wisdom from Chinese traditional culture is the power to promote the sustainability and high-quality development of these systems. The key eco-wisdom of AHSAECs is to integrate aquaculture with livestock and poultry breeding and planting through the harmless treatment and recycling of agricultural wastes, which is conducive to the aquatic ecosystem conservation and sustainable resources utilization. Nowadays, it is urgent to preserve the eco-wisdom by establishing ecological museums to realize the productive protection and inheriting development of the heritage systems.
