This research aims to study the temporal change of vegetation cover in Bahla City and its relationship with local climate, focusing on the impact of temperatures, relative humidity, and rainfall amounts on plant density. Bahla City is an arid and semi-arid region, where vegetation cover serves as a sensitive indicator of climatic fluctuations and directly affects ecosystem stability and hydrological balance. The study was based on analyzing NDVI data extracted from satellite images, alongside field climatic data collected according to GLOBE protocols, such as temperature, relative humidity, and rainfall amounts. Research methods included using descriptive statistics to calculate averages, maximum and minimum values of vegetation cover, and correlation analysis between NDVI and climatic variables to understand the relationship between vegetation cover and weather factors. The results showed a noticeable improvement in vegetation cover density between 2023 and 2024, with average NDVI increasing from 0.33 to 0.41, along with increases in minimum and maximum values, reflecting a general improvement in vegetation status. No rainfall was recorded during the study period, indicating that vegetation cover depends on alternative water sources, such as artificial irrigation and soil-stored moisture. Moderate temperatures (24–28°C) and medium to high relative humidity (30–58%) helped promote plant growth and reduce water stress, positively reflected in NDVI values. These results provide accurate data to support decision-makers in natural resource management, combating desertification, and promoting sustainable development in Bahla City. They also contribute to increasing community awareness of the importance of preserving vegetation cover as one of the fundamental factors in facing the effects of climate change.
