This volume presents a collection of scholarly contributions that examine contemporary challenges and innovations in sustainable agriculture and food systems. The chapters collectively address the efficient use of resources, environmental sustainability, and technological advancement, offering interdisciplinary perspectives that link local practices with broader global sustainability frameworks. At the local and agroecological level, the chapter on the self- consumption of compost derived from household organic waste in South Borgou, Benin, investigates circular approaches to soil fertility management and waste valorization. It provides empirical insights into how household- based composting can enhance market gardening productivity while contributing to environmental conservation and rural livelihoods. The volume further explores structural and technological transformations within food systems. The chapter on plant-based milk analyzes its role as a complementary component of sustainable food systems, while the contribution on precision spraying and plant-by-plant AI management examines data-driven agricultural technologies aimed at improving input efficiency, reducing environmental externalities, and increasing production accuracy. Concluding the volume, the chapter on sustainable agriculture with an emphasis on livestock husbandry addresses integrated and responsible livestock management practices. It situates livestock systems within a sustainability framework that balances productivity, animal welfare, and environmental impact, thereby reinforcing the need for holistic approaches to agricultural development.
