Abstract

Water is an indispensable element for all living organisms for sustaining human existence, food security, societal advancement, and biodiversity. Due to global climate change, an increase in the shortage of fresh water supply is noticed leading to global water crisis. Traditional and non-traditional approaches as solutions against global water crisis were reported. Applied nanotechnology might support and provide promising strategies to overcome many global issues like global water crisis. The suggested applied nano-solutions may include nanofertilizers, and nano-sensors, and nano-management of wastewater. Nanofertilizers have distinguished features against global water crisis, which can increase the water use efficiency by cultivated crops, especially under stressful conditions. Many reports confirmed that applied nano-fertilizers can directly and/or indirectly save water along with an effective role of such fertilizers under water stress. This role of nanofertilizers may back to its features that enhance productivity of cultivated plants under water stress through physiological, biochemical, and anatomical issues. This study opens many windows towards the expected issues of nanofertilizers against water crisis including direct and indirect attributes. Further studies in this important global issue are needed especially under the global challenges with a great concern on global climate change.
