Assessing the Impact of Climate Change on Food Security Indicators: An Empirical Study in Algeria (2000-2023)

The governments of Algeria and Saudi Arabia, like all decision-makers in the MENA region, place central importance on the issue of food security, considering it a matter of national security for these countries. This issue is influenced by internal and external factors, including geopolitical, economic, climatic, and other elements that can complicate the achievement of food security. This econometric study focuses on assessing the impact of factors influencing food security, represented by total cereals production in Algeria, on greenhouse gas emissions—specifically carbon dioxide—precipitation, and cultivated land area for 2000-2023. Using the ARDL model, the study concluded a positive relationship between grain production and the variables of precipitation and cultivated land area in both the short and long term, while production is negatively affected by carbon dioxide emissions in the short term
