Recognizing the increasing urgency of climate change, many regional administrations are currently developing tailored adaptation strategies primarily grounded in the knowledge of the unique characteristics of their territories, including climate patterns, local atmospheric dynamics, topography, and, more importantly, environmental and socio-economic factors. Yet, exploiting this wealth of information to design effective climate strategies is still a problem. This study outlines the approach adopted to lay the foundation for the mitigation and adaptation strategy of the Trentino region, a mountainous area in northern Italy and part of the European Alps. Here, we present three major steps of this approach, highlighting the collaborative effort of several actors s: 1) Preparing a scientific report reviewing the existing knowledge basis about climate change impacts in the region, 2) Disseminating a synthesis to the general public, and 3) Creation of reference climate scenarios. The literature review revealed significant diversity in the extent and in the depth of analysis from scientific contributions in different sectors regarding the impacts of climate change in Trentino. This diversity was reflected in the informative report, in which a methodical process was employed to simplify and synthesize technical information without sacrificing scientific accuracy. We created climatic scenarios that balance e multiple aspects such as topography, data availability, and stakeholders needs. To achieve this we used a layered approach including spatially aggregated results, statistical downscaling, and high-resolution numerical simulations with a convection-permitting model. This study indicates a general increase in temperatures, with a more pronounced rising of winter minima and summer maxima. Extreme precipitation is expected to increase in intensity and frequency, while seasonal variations depend on the emissions scenario.
