Fuente: Agri-Waste and Microbes for Production of Sustainable Nanomaterials Nanotechnology emerges as a pivotal and transformative advancement in twenty-first century, offering significant potential to revolutionize agricultural practices and foster sustainable development. By enhancing management and conservation strategies while minimizing input waste, nanotechnology presents a promising avenue to address the mounting challenges posed by climate change and the strain on global resources driven by a growing population. Consequently, the imperative to ensure food security becomes increasingly urgent. Researchers have undertaken numerous projects to develop innovative techniques that promote sustainable agricultural systems while minimizing adverse impacts on the environment. Advancements in nanomaterial engineering have revealed that the use of nano-fertilizers in unfavorable conditions has the capacity to enhance crop yields. Nanoparticles, serving as specialized carriers for agrochemicals, facilitate targeted and regulated nutrient delivery, thereby providing increased crop protection. High-tech agricultural farms are further supported by advanced nano-devices, such as nano-biosensors, which offer distinct advantages and direct applications in precise input management and control (including fertilizers, insecticides, and herbicides). This comprehensive review examines recent endeavors to harness nanotechnologies in novel ways within the agricultural sector. These endeavors hold great potential to effectively address the escalating demand for sustainable food production in the face of climate change challenges.
