Abstract
The global population growth is driving up the demand for agricultural products, while traditional farming methods like those from the Green Revolution are becoming unsustainable due to climate change. To address these challenges and ensure agricultural sustainability, innovative techniques, such as nanotechnology, are essential to meet rising food demands and enhance agricultural sustainability. Nanotechnology, which promotes a more sustainable and resilient agricultural system while enhancing food security, is a key catalyst for the Agri-tech revolution. This review offers a progressive analysis of nanotechnology's role in managing plant stress. It explores how precision agriculture, particularly via nanosensors, is enhancing our comprehension of plant stress conditions. The integration of nanotechnology with genetic engineering methods, notably CRISPR-Cas technology, is also examined. Furthermore, the review considers the potential toxicological effects of nanoparticles (NPs) on both the environment and plants. Our review has the potential to make a significant impact on human food security by enhancing food production and availability while promoting sustainable agricultural practices. By tackling these challenges, we can contribute to a more reliable and sustainable food supply for the global population.
