Résumé :
|
This thesis examines the impact of climate change on the Safsaf watershed, integrating land-use analysis, land-suitability assessment through the Analytical Hierarchy Process (AHP), and climate-environment relationships based on satellite indices. The study aims to understand how climate variability affects water availability, agricultural potential, and the functioning of irrigation systems. An integrated methodological framework was developed to capture spatial and temporal variability. AHP was used to evaluate land suitability for agriculture, considering factors such as slope, aspect, and elevation. The analysis of land use was conducted through Sentinel World Dynamic imagery, enabling a comprehensive assessment of agricultural and urban distributions. Data from geological maps and satellite imagery (including NDVI and NDWI) assessed land use, vegetation health, and water availability. Correlation analysis explored relationships among temperature, vegetation, and moisture. And the surface area of Zerdaza Dam was estimated via NDWI and Modified NDWI (MNDWI) from Landsat 8, underscoring the intricate effects of climate change and land variables on irrigation systems. Key findings indicate that only a limited portion of the watershed is suitable for sustainable irrigation, with many areas constrained by environmental factors. Land use changes, driven by urban expansion and degradation processes, reveal increasing stress conditions characterized by temperature variability and low surface moisture. Correlation analysis shows that temperature influences water availability more significantly than precipitation. The analysis of the Zerdaza Dam highlights water scarcity and prioritization during dry periods. Ultimately, the findings suggest that irrigation systems are highly vulnerable due to reliance on limited and contested water resources, necessitating a shift from traditional practices to integrated and adaptive water resource management strategies.
