The One Health approach in urban ecosystem rehabilitation: An evidence-based framework for designing sustainable cities.

Rapid urbanization has led to negative, and sometimes unintended, consequences on biodiversity and human health. While cities offer numerous advantages in meeting the basic needs of a growing population, they also pose less apparent and longer-term health costs. To address the multifaceted impacts of urbanization, an evidence-based design framework for establishing mitigation and regeneration actions is essential. Via a "One Health" approach, this perspective provides recommendations and strategies for the urban ecosystem rehabilitation of future cities, placing biodiversity and ecosystem services at the core of designing healthy and sustainable urban spaces. The framework we propose is based on a Hub and Spoke model to integrate diverse perspectives from public and private sectors and declined in a six-building-blocks structure. This will ensure that efforts are sustainable, health-centered, socially inclusive, and grounded in high-quality data, reinforcing the essential connection between healthy environments and thriving communities.
