In the current context of climate change impacts, it is imperative to adopt sustainable agricultural practices with crops as the central focus of farming. Resource constraints due to land degradation, along with deteriorated soils, limited availability of irrigation water for crop production, and challenges posed by biotic and abiotic stresses, necessitate the implementation of sustainable agriculture practices to meet future food security demands in the face of an ever-growing population. Novel techniques and emerging technological innovations in the field of crop breeding and biotechnology offer potential solutions to address the threats posed by numerous factors to global food security. The integration of these crop breeding techniques with large-scale agroecological system-based approaches holds significant promise for providing long-term solutions. Speed breeding to rapidly reduce the breeding cycle, genome-editing tools to alter the expression of traits of interest, transgenic approaches to modify plant gene sequences for desired traits, and high-throughput genomic information of crops to augment crop breeding are examples of tools and techniques that can shape the future of crop systems. With the rise of artificial intelligence and machine learning, big data analysis is now revealing large-scale patterns in how crops adapt and highlighting the policy changes needed. To reduce environmental challenges, help double farmers’ incomes, and enhance the societal benefits of sustainable crop systems, now is the ideal time to apply advanced knowledge and experience. By integrating sustainable crops into agricultural practices, we can make significant progress toward achieving global food security.
