    This study utilized the contingent valuation method to estimate the value of water-related ecosystem services (ES) in Vietnam, focusing on provisioning and regulating services for addressing water scarcity (WS) in rice farming. By incorporating gender and climate change perceptions, it expanded the existing literature on valuing river ecosystem services. The findings showed a significant number of households experiencing severe water scarcity in the past five years, with over 70% facing occasional or regular WS in the last 12 months. Rice farmers were willing to adopt coping measures and preventive practices to preserve water-related ES, recognizing their importance for sustaining rice cultivation. Farmers demonstrated willingness to contribute financially to restore and maintain water-related ES in rivers and canals. The median willingness to pay for restoration was VND188,300/ha, with estimated values of US$2,898,133 for a 10% affected area and US$23,185,068 for an 80% affected area over five years. Perception of WS severity and associated risk positively influenced households’ decisions to contribute financially. These findings have policy implications and provide insights for effective coping strategies against WS, enhancing water-resilient agriculture in the Lower Mekong Basin.
