Nature-Based Solutions Approach to the Development of Water Supply System from Surface Waters of Pleshcheyevo Lake Basin

The article describes the use of the Nature-based solutions approach (NbS) for water management. The case study of the Pleshcheyevo Lake basin shows that the integration of the cost-benefit analysis and the Rapid Impact Assessment Matrix (RIAM) makes it possible to significantly reduce the cost of analyzing options for the water supply systems development towards sustainability and reduce the assessment time. The article shows the potential for the use of the synthesis of expert and economic analyses principles while implementing the concept of nature-based solutions in water management. In practice, it allows supporting search and preliminary selection of effective nature-based solutions in water management both in low-budget and high-cost projects.
