Egypt faces many challenges in achieving food security. Climate change is one of the obstacles facing agricultural production in achieving self-sufficiency in strategic crops. Agricultural sector emissions amounted to about 2.57 million tons of carbon, representing1.25% of the total emissions for different sectors in 2017/2018. This may negatively affect the productivity of major crops in Egypt, This leads to a decrease in farmer incomes this leads to a decrease in farmers 'income, which is reflected on the extent of the contribution of the agricultural sector to Gross Domestic Product (GDP). This research aims to estimate the impacts of increasing the production of crops, livestock and aquatics production on achieve the food security, in the same time decreasing the emissions of greenhouses gasses in Egypt" Also mitigating climate change without having a negative impact on the environmental, The average supply of protein of animal origin recorded the highest contribution rate (0.970)% from total variance, followed by the average protein supply reached (0.948)% from total variance, The energy supply of grains, roots and tubers recorded the lowest percentage (-0.137)% from total variance, also, there is a strong correlation between the average supply of protein of animal origin and the main component (food availability), The study recommends the use of modern agricultural methods, , by supporting small farmers to the application of climate-smart farming systems in Egypt, and provide the necessary funding To continue research in the field of agricultural production. Providing farmers with various extension services, increase organic agriculture area, and providing full support to organic farms, which help increase Egyptian exports of agricultural products.
