Prevailing conditions of the climate have had a drastic effect on global food security. Various types of stresses have been producing havoc by reducing crop production. One of the primary causes has been observed in the form of drought. Drought generally has various kinds of impacts on human life, but its main victim is food crops. A plant has specific defense systems to combat and stay unchanged in an environment with water stress, but this ability decreases as the lack of water increases for a long time. The average globular yields of these primary agricultural products are admirably purposeful by enactment of crop performance in millions of fields distributed transversely in series of management practices for soil and climatic regimes; even with the global food supply complications, here we illustrate some simple measures of most widely germinated crops based upon the location, temperature, and precipitation. The types of responses, like reactive oxygen species (ROS), root signaling. Antioxidant enzymes, photosynthesis, etc., discussed in the context will help us to understand the situation with more clarity. The possible mitigation measures are also discussed in detail. A plant may be mitigated at different levels including breeding progress in drought condition, cellular and molecular adaptations, or using supplemental irrigation practices. In this paper, authors have reviewed all the aspects that encapsulate drought stress and its response to major food crops.
