Abstract
The ecological impact on food production through innovative and green approaches. These approaches often involve "pollutants amputation," a term that describes removing or mitigating harmful contaminants and waste, ensuring the water used in food systems remains clean, safe, and sustainable (Madhav, 2020) 1In this special issue, the special focus was to search such methods that can help in the protection of our environment as well as can be used for water purification. In this regard, five manuscripts were submitted, out of which one was rejected and four were accepted after revision for final publication. The work presented in this issue gives a solution for the degradation of Methylene blue dye from wastewater by employing Biochar blended with Zinc Oxide and Copper Diphenyl Amine (Aroosh et al.) and Pectin functionalized with Cu/Fe nanoparticles (Faiza et al.). These methods are low-cost as well as eco-friendly. Similarly, waste management for Congo red dye is addressed by using deoiled seeds of citrus plants by enhancing their adsorption potential with nanoparticle loading (Misbah et al.). This method provides an efficient method for large-scale application by using agro-based waste material as adsorbent. A review article was published in this issue which addresses water fertilizers coupling technology for crop yield (Yingying et al.). This review article presents different technologies used comprehensively.In conclusion, the road to sustainable food systems is closely intertwined with the need to protect and manage our water resources. By adopting green approaches that focus on pollutant amputation, we can significantly reduce the water footprint of food systems, safeguard aquatic 1 Madhav, S., Ahamad, A., Singh, A.
