This book brings together interdisciplinary perspectives that address sustainability in food production, agriculture, and environmental education. The chapters highlight how environmental engineering principles, agricultural efficiency, and ethical frameworks can collectively contribute to responsible resource management and long-term ecological balance. The chapter Aquaculture Water Quality Management: Environmental Engineering Approaches for Sustainable Fish Production examines engineering strategies for maintaining optimal water conditions in aquaculture systems, emphasizing environmental protection alongside productivity. This is complemented by The Efficiency of Nitrogen Use in Cereal Agriculture in Algeria, which analyses nutrient management practices aimed at improving crop yields while reducing environmental impacts in arid and semi-arid agricultural contexts. The final chapter, Islamic Eco-Theology in Environmental Engineering Education in Indonesia, introduces a value-based and educational dimension by exploring how ethical and theological perspectives can be integrated into engineering curricula. Together, these chapters offer a holistic view of sustainability that combines technical solutions, agricultural innovation, and cultural-ethical considerations, making the book a valuable resource for researchers, educators, and practitioners alike.
