Traditionally, agriculture and the food industry focused on maximizing productivity and financial returns, leading to the overexploitation of natural resources and increased waste. This has resulted in significant environmental damage, including ecosystem loss, climate change, and health issues from pesticide exposure. Agriculture accounts for 85% of global water use and is a major source of greenhouse gases. The food industry also consumes large amounts of energy and generates substantial waste, contributing to environmental and health problems. To address these issues, there is a growing need for sustainable practices that minimize environmental impact while meeting increasing food demands. The transition to a more efficient, profitable, and environmentally friendly agri-food system is essential for economic and environmental sustainability. Modern technologies, such as nanotechnology and Internet of Things (IoNT), offer promising solutions. These technologies can optimize production, reduce resource use, and minimize waste. They enhance food safety, improve crop and livestock production, and reduce the use of pesticides and fertilizers. Additionally, they enable real-time monitoring and targeted actions, such as controlled release of agrochemicals and water and soil remediation. The integration of nanotechnology and IoNT in the agri-food sector can significantly improve sustainability, ensuring food security while protecting the environment and human health.Traditionally, agriculture and the food industry focused on maximizing productivity and financial returns, leading to the overexploitation of natural resources and increased waste.
