This research explores the impact of soil type on relative humidity across four diverse regions in Israel—Dimona, Dir Hanna, Rosh HaAyin, and Herzliya. Using the GLOBE SMAP protocol, students conducted a comparative study to analyze soil moisture retention, following standardized methods to ensure accuracy. Key Findings: Clay soils (Rosh HaAyin) retained the highest moisture levels due to their fine particle size and high water absorption capacity. Sandy soils (Dimona) exhibited the lowest moisture retention, largely due to high evaporation rates in arid climates. Red loam (Dir Hanna) showed moderate moisture retention, striking a balance between water absorption and drainage. Mixed sandy-clay soils (Herzliya) had fluctuating moisture levels, influenced by proximity to the Mediterranean Sea. Significance and Impact: The study highlights the critical role of soil type in water conservation, agriculture, and environmental sustainability. It provides valuable data for land-use planning and efficient irrigation strategies, particularly in water-scarce regions. Beyond its scientific value, this project served as a collaborative initiative between Jewish and Arab students, fostering cross-cultural cooperation and environmental awareness. The students participated in cultural exchange sessions and worked together to analyze and interpret their findings, reinforcing the role of science as a unifying force. Future Research Recommendations: Expanding seasonal observations to assess year-round soil moisture variations. Integrating predictive modeling to enhance understanding of long-term soil-climate interactions. Examining additional environmental factors such as vegetation cover, erosion, and urbanization to refine insights into soil and water conservation. This research contributes to both local and global scientific efforts, providing essential data for sustainable resource management and climate adaptation strategies.
