摘要

Climate change is already at its peak, and the world population will continue to increase; in this situation, we face significant challenges in the food system. Anthropogenic actions are the main cause of climatic change. One of the major risks to world health in the twenty-first century, according to the World Health Organization, is climate change. The environment is gradually being affected by climate change. People are now facing increasing heat every year, flooding, more diseases, increased water and food scarcity, droughts, sea level rise, etc., which are the impacts of climate change. All these impacts will directly affect the agriculture sector; when the agriculture sector is affected, food production decreases, thereby increasing the price of the available food products. Introduction of climate-resilient crops is hence essential. The field of gene editing is helpful in this situation for improving the agriculture sector. It includes adding new genes, changing how genes are regulated, or modifying or removing existing genes. Zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and CRISPR-Cas9 are a few of the techniques that can be used to do this. The invention of CRISPR/Cas systems has greatly increased the accuracy and productivity of producing modifications. Since the discovery of CRISPR/Cas-9, it has been used to genetically alter food to increase its nutritional content, shelf life, drought tolerance, and disease resistance; it is an existing addition to the field. With the help of the CRISPR technique, drastic changes can be made in the agriculture sector. It is also reported that many changes can be made in the agriculture sector. To mitigate the effects of climate change, gene editing has already been successfully used on plants. Successful gene editing in various crops like rice, wheat, cassava, potato, tomato, etc., gives the idea that gene editing can help crop improvement for sustainable agriculture. Both the biotic and abiotic factors affect the plants. CRISPR can help the plants in all conditions for their improvement. Scientists are attempting to genetically modify these crops to make them resistant to these obstacles and challenges. The global food crisis is primarily being resolved in three ways by CRISPR. It has the power to replenish food sources, support plant survival in stressful conditions, and enhance plant health by promoting growth. Hence, this chapter discusses how CRISPR is going to solve the food crisis in the scenario of global warming.
