How utilizing the genes involved in drought tolerance could tackle the climate change-related food crisis?

The global population is expected to increase by 10 billion by 2050,the demand for food and water is also likely to increase.Several factors intensify the growing water scarcity,such as inef-ficient water use in the food value chain and inadequate infra-structure to save water.The changing climate also exacerbates the rising temperature by making the drier areas drier and nega-tively impacting agriculture production in most parts of the world.A decrease in precipitation has been observed in the tropics and sub-tropics,such as the Sahel region of Southern Africa,the Mediterranean,South Asia,and the Southwest of US since 1970().
