Promote integrated planning and management: China should promote integrated planning and management of water, energy, and food resources at the regional and local levels. This should involve the development of integrated water, energy, and food plans and the establishment of coordination mechanisms to ensure effective implementation and monitoring.
Invest in green technologies and circular economy approaches: China should invest in green technologies and circular economy approaches that improve the efficiency and sustainability of water, energy, and food systems. This includes the development of low-carbon energy technologies, smart agriculture and irrigation systems, and sustainable food production and processing methods.
Enhance climate change adaptation and mitigation strategies: China should enhance its climate change adaptation and mitigation strategies to address the impacts of climate change on the water-energy-food nexus. This includes the development of climate-resilient infrastructure, the promotion of low-carbon energy systems, and the adoption of climate-smart agricultural practices.
Strengthen public awareness and participation: China should strengthen public awareness and participation in the water-energy-food nexus approach and green development agenda. This includes the development of education and outreach programs to promote awareness of sustainable consumption and production patterns, and the engagement of stakeholders in the development and implementation of policies and programs.

Promoting the water-energy-food nexus under green development in China requires integrated policy frameworks, technology development, climate change adaptation and mitigation strategies, institutional and governance reforms, promotion of a circular economy, and public participation and awareness. The water-energy-food nexus approach provides a useful framework for promoting sustainable and integrated development in China. By adopting a coordinated approach to managing water, energy, and food resources, China can achieve its green development objectives and contribute to global efforts to address climate change and promote sustainable development. The successful implementation of these measures can help achieve sustainable resource management and promote sustainable development in China.
