**5. Food security and sustainability**

Sustainability is a generic notion applicable to food security as a whole, representing more than its particular dimensions. The idea of sustainability emphasizes that continuous healthy well-being across the lifetime and future generations is the objective of long-term food security [25]. Food insecurity can happen whenever there is an interruption at any step along the pathway from availability to use and consideration to stability because the four dimensions are linked and interdependent. However, the most significant complication and tragedy arise from these considerations. As can be seen from the definitions of each term, the concept of "sustainable diets" is an attempt to bridge the gap between "sustainability" and "food security" in order to create "holistic, sustainable food systems." Diets are considered sustainable if they "have preventive aspects, reverential of biodiversity and ecosystems, socially desirable, available, economically sustainable, low-cost; nutritionally adequate, hygienic, and healthy; and enhancing human as well as natural resources" [23]. Whereas "a sustainable food system ensures Food Security and Nutrition for everyone in that way which does not hurt the social, environmental and economic bases for ensuring FSN for future generations" [26].

The widespread consensus among nations worldwide is that climate change poses a risk to the permanent viability of food security. However, the processes included in food systems are responsible for approximately (20–30%) all greenhouse gas emissions related to human activity, and as a result, climate change occurs [27]. It was observed that a relationship that might be described as a "trade-off "
