Resource description:

This infographic presents the Carrión de los Céspedes (Spain) Case Study from the NATMed PRIMA Project, demonstrating how NbS can improve resilience and promote sustainable water reuse in Mediterranean agricultural systems 

The site integrates ten constructed wetlands as part of an upgraded water treatment facility, enhancing nutrient removal and water quality while supporting biodiversity. Floating gardens reduce evaporation, improve water quality, and create habitats for aquatic species. Complementary ultrasound technology helps control algae and bacteria in storage lagoons, reinforcing nature-based treatment processes 

A meteorological station and advanced filtration systems support smart water management, while treated water is reused to irrigate nearby olive groves, contributing nutrients to soils and increasing water retention capacity 

This case study highlights how hybrid NbS and technological solutions can strengthen climate resilience, optimize water reuse, and support sustainable agricultural production in water-scarce Mediterranean regions.
