The application of engineering to the production of sustainable food systems is examined more closely in this review. It deals with the important trifecta of the food system: issues such as food security, harnessing natural resources, and the catch-22 of sustainable economic development. Thus, it has shown very new innovations in food processing leading to an enhancement in the safety and shelf life of food by methods like high pressure preservation and bio preservation. It also addresses energy efficiency endeavours and disposal mechanisms particularly those revolving on the conversion of waste into energy. New technologies like Artificial Intelligence, the Internet of Things, and blockchain technology will also be covered as these if properly deployed can significantly reduce inputs because they will help in utilising all available resources in farming and help in providing traceability in the food chain. This review underscores the fact and necessity of technology adoption towards the realization of the sustainable development goals for food security, the environment, and climate change resilience. Combining these technologies the paper concludes that this would make a sustainable global food economy, efficient and capable of addressing some of the most dire contingencies of the future.
