Abstract
This study analyzes the olive tree in the Menara Garden (Marrakech) to elucidate its role in the resilience of semi-arid urban agroecosystems. By combining hyperspectral remote sensing, bioeconomic modeling, and biophysical analyses, it quantifies the ecosystem services provided by the park (100 ha, 10000 trees). The results demonstrate optimal microclimate regulation (evapotranspiration accounting for 53.21% of the water balance), significant pollutant sequestration (carbon dioxide (CO2), ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), particulate matter (PM)), soil stabilization, and circular valorization of 268 t/year of biomass. These performances stem from adaptive traits (adjustable stomatal conductance, phenotypic plasticity), enabling water savings of 35 ± 5%. The study proposes a framework integrating plant physiology, ecosystem services, and SDGs, advocating for urban policies refocused on green infrastructure as pillars of sustainability in semi-arid zones.Keywords
