Nowadays, food security is of prime importance; because not only does it overcomes hunger, poverty and malnutrition, but it also determines the national security and political and economic sovereignty of states. However, according to the FAO report (2021), 2.37 billion people (nearly one in three people) in the world did not have adequate food availability in 2020. The green revolution created an era of extraordinary food production worldwide, but agriculture-oriented developing countries face adverse impacts such as loss of ecosystem quality and biodiversity and environmental degradation. Besides, several challenges such as population growth, pollution, natural resource depletion, agricultural land conversions and climate change are further developing concerns in achieving food security.
