Arid and semi-arid environments characterize the Middle East and North Africa (MENA) region. Climate change posed significant effects in these regions making them drier and suffer water scarcity especially in recent years. In this research, we used the enhanced vegetation index (EVI) as an indicator of this drying trend over the MENA region the past 20 years. We used harmonic analysis model for comparison with observation data to reveal trends in some capital cities within the MENA region, namely, Tunisia, Egypt, Iraq, Saudi Arabia and Iran. The models performed well and different vegetation changes among these countries were observed. The results revealed a changing behavior over different areas among the MENA region. For instance regions such as Iraq and middle Saudi Arabia suffer drier climate, whereas parts of Iran is more humid.
