With the advent of civilization, soil-based cultivation is now facing many challenges like decrease in per capita availability of land, declining fertility status of the available land. Due to rapid urbanization and industrialization as well as melting of icebergs (as an obvious impact of global warming), arable land under cultivation is further going to decrease. Sudden natural disasters, climate change and unrestricted utilization of chemicals for agriculture purposes cause the depletion of soil fertility and quality. That is why, scientists have developed a new alternative approach for cultivation system namely soil-less cultivation or hydroponics. Hydroponics is a method of growing plants in a water based, nutrient rich solution under protected conditions. The quality of yield, taste and nutritive value of end products produced through hydroponics is generally higher than the natural soil-based cultivation. Being cost effective and eco-friendly and its suitability to produce the different kinds of fruits, vegetables and fodder as well as its ability to meet the global nutrition demand with making advance future, hydroponics is gaining popularity all over the world, both in developed as well as developing countries. Thus, hydroponics could be a sustainable and emerging climate smart technology for attaining food security in the near future.
