Fuente: Agri-Waste and Microbes for Production of Sustainable Nanomaterials Future food security faces enormous challenges due to the increasing population growth and the changing climatic conditions. The growing demand for a varied range of robust, nutrient-dense crops is outpacing the productivity of conventional farming methods. Under these conditions, synthetic nanomaterials show great promise as revolutionary instruments for transforming agri-farming systems. The potential of nanomaterials to improve tolerance and sustainability in sophisticated agri-farming systems is explored. This chapter describes the various uses of nanomaterials in pest and disease control, crop stress tolerance, soil health management, and precision agriculture. Engineered nanomaterials (ENMs) are designed for targeted delivery of nutrients and pesticides, maximizing their efficacy while minimizing environmental impact. This includes innovations like controlled-release fertilizers and nanoparticle carriers for precise disease control. We examine how nanomaterials can boost plant tolerance to abiotic stresses like drought and salinity. The chapter strongly emphasizes responsible development and implementation techniques while critically analyzing the advantages and disadvantages of employing nanomaterials in agriculture. The potential risks and benefits associated with nanomaterials in agriculture are critically evaluated. Lastly, the problems and future paths for using nanotechnology to power sustainable and resilient agri-food systems are also discussed.
