Urbanization is expected to intensify in the coming years, while climate change impacts will increasingly affect urban environments. In this context, Nature-Based Solutions (NBS) have emerged as effective strategies to restore urban ecosystems, reduce climate-related risks and generate multiple co-benefits. However, their evaluation remains complex, as their multidimensional effects are difficult to capture within a single assessment framework. Most existing evaluation methods tend to treat the economic dimension as a separate domain, structurally disconnected from environmental and social considerations, an approach that often requires complex monetization procedures and ex-post integration mechanisms. This research thesis aims to address this gap by proposing a spatially grounded multicriteria framework, capable of integrating environmental, economic, and social criteria without forcing their reduction to a single monetary-equivalent scale.
