Sustainable Hybrid of Agriculture and Urban Ecology Base on Web 3.0 Technology

This paper addresses the global issues of food scarcity and ecological imbalances, resulting in hunger, malnutrition, and health complications. To foster sustainable development and harmonize human-ecological balance, an interdisciplinary approach utilizing web3.0 technology is adopted to promote the integration of agriculture and urban environments. The research explores the web3.0 technology to select crops and plans manual work by utilizing the internet of things and blockchain. This facilitates real-time monitoring and recording of environmental, climate, and soil information, allowing for the selection of suitable crops in specific areas, improving agricultural efficiency, and ensuring food safety. The study also investigates the destination of agricultural products, selling them directly to the public using web3.0 technology to provide green ecological food while ensuring the income source of low-income farmers. This strategy promotes economic growth and achieves a virtuous circle of economy and ecology. In addition, the study explores the recycling of agricultural plants, aiming to identify the most optimal recycling program through the utilization of web3.0 technology. By implementing this approach, we can facilitate the sustainable development of agriculture and rural areas while mitigating the impact on the environment. At last, a sustainability model based on trust mechanisms, cooperation and benefit mechanisms, and coordination mechanisms is developed, mobilizing multiple sectors to ensure sustainable integration of Web3.0 agriculture and ecological systems for economic growth and ecological balance. To effectively address the food and ecological crisis, the study puts forward a web3.0 technology-assisted sustainability model and multi-participation sustainability model based on web3.0 technology, which can promote the benign interaction between cities and agriculture and build a more beautiful and livable city, and im-prove food security and environmental preservation.
