Resum:	Water Yield Ecosystem Service (WYES) is one of the main benefits of natural resources and have an essential role in agriculture, industry, and energy generation for social and ecological function. Quantity and quality of water availability is critical for the socio-economic development, which directly influence sustainable development of the social and ecological systems, especially in metropolitan areas facing water scarcity. This paper presents a quantifying assessment and mapping WYES in the Qazvin metropolitan region (Iran), using the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model to address water scarcity under two scenarios: the first is Continuing the Current Situation Scenario (CCSS) and the second is Land use Planning Scenario (LPS) which incorporates of Land Use and Cover Change (LUCC) under landscape ecological capability. The result shows, the estimation of overall water yield in the current situation is 752. 02 Million m3, in the CCSS will decrease to 575. 32 Million m3, and in the LPS will decrease to 602. 74 Million m3. This study guides decision makers and is essential for the development of metropolitan green infrastructure strategies in arid environments that will ensure their future water supply in climate change scenarios.
