Climate change affects the food system all around the world. It affects the dimensions of food security, starting from availability of food, access, utilization and food stability. The repercussions of climate change will be different in different regions. Hence to satisfy the needs of all the people is a task of the era. The most vulnerable people to vulnerable people to such changes are those who are already hunger and malnutrition. Reduced accessibility and stability of food to vulnerable groups is the serious issue on food security. The sustainable development goals 2030 by United Nations are the only step taken at the international to solve food crisis. However there are two ways, either of which can be implemented to combat climate change. Firstly, should try to control climate change through mitigating factors or develop ourselves and the environment to the changing climate. The annual occurrence of disaster has increase three time than that 1970s & 1980s. Drought has been major cause for food insecurity followed by floods, production cost, storm, pests and diseases and wildfire. Therefore as FAO stated, global investment must be made for resilience and disaster risk reduction, were countries should share data, statistics and information which acts as an evidence to reduce the climate extremes. Countries must adopt multi-sectoral system to anticipate, prevent, and prepare for global environment change. New innovations should arrive into practice without delay in regional countries. Above all the public-private partnership is essential to understand the change and be prepared to fight against it.
