Agriculture is directly related to food security, which is highly dependent on and significantly impacts resources and the environment. Sustainable agriculture development is key to achieving the sustainable development goals. Frontiers, hot topics, and trends of sustainable agriculture development were summarized for scientific research and decision-making by CiteSpace based on 1 174 papers published in the Web of Science and 1 043 papers published in China National Knowledge Infrastructure from 2000 to 2019. Results showed that the frontiers were mainly focused on"food system resilience and food security", "ecological intensification and sustainable intensification", "agricultural muti-functionality and urban agriculture", and"trade-offs and synergies of ecosystem services in agroecosystem". Hotspots included how climate change impacts agricultural systems and its adaptive management, ecosystem services management in agro-ecosystems, and the environmental impact assessment of agricultural activities and integrated sustainability assessment of an agricultural system. It is suggested that the coupling mechanism of the"climate-land-water-energy-food"nexus should be further analyzed, and"influencing factors-action mechanisms-regulation methods"of agro-ecosystem should be systematically studied in the future. |
