The Effects of Climate Change on Food Security

In the current situation, ensuring food security and maintaining it, especially due to growing demand and significant population growth on the one hand and excessive and incorrect use of limited and non-renewable resources and reserves and the emergence of challenges such as climate change on the other hand is very important.  According to the World Bank, food security is achieved when all people have access to enough food at all times to live a healthy life. This has three aspects: "food availability", "access to food" and "sustainability in food intake" (Eslami AR, ۲۰۲۱). The threat of declining food security due to climate change is one of the major challenges of the ۲۱st century. The impact of climate change on agricultural benefits and food security depends on the scale of climate change (Marzban et al., ۲۰۲۳) .
