THE GLOBAL food production faces great threats including the changing in climate, and different environmental stresses, which may decrease it causing global food insecurity. So, many new approaches and technology are become crucial to solve this problem like nanotechnology. Nanofertilizers, like nano silica, have several benefits including higher use efficiency, improving nutrients uptake, higher plant growth and vigor, higher crop yield and its quality, reducing the environmental stress on cultivated plants, and higher economic feasibility compared to traditional fertilizers. Nano-silica (SiO2-NPs), as less toxic and immensely stable, has several applications especially in the medicine and agricultural fields. Silica nanoparticles has been also applied for supporting cultivated plants under biotic/abiotic stress, the nano-remediation of the environment pollutants (like heavy metals, organic pollutants and radioactive compounds in soil and water), and water purification. This is a call by EBSS for different kind of articles including original articles, mini-review or reviews and others. The environmental dimension of silica nanoparticles in the medicine, industry, or agricultural fields has a great priority to publish beside other new approaches in the security of food, soil, water and energy.
