Abiotic stresses adversely affect plant growth and ultimately crop productivity. Of these, water-logging is the most widespread and most commonly experienced stress factor. While water is essential for all plant growth and development processes, waterlogging is an obstacle to sustainable agriculture. Recent FAO reports indicate that universal crop production must be enhanced by 70% by 2050 in order to meet the growing demand for food by an estimated 2.3 billion people. As demand for food increases, there is an urgent need to identify environment-friendly strategies capable of being accepted and adopted widely to enhance crop yields and mitigate the effects of climate change. Nanotechnology as a science of manipulating materials at the nano-scale has significant potential to enhance agricultural productivity by nonconventional means. This technology has been gaining momentum lately as a possible solution to reduce the adverse effects associated with various stresses, particularly with waterlogging, to enhance future food security. This paper discusses the potential applications of nanoparticles to achieve sustainable crop productivity, together with their impact on the mechanism of tolerance to waterlogging stress.
