In order to increase the climate resilience of a city after a previous initial city gaps assessment, adaptation (or resilience) strategies have to be defined. However, the creation of a database of adaptation measures is essential as starting information. It has to be noted that while an adaptation measure is a specific intervention to address a specific climate hazard, an adaptation strategy is a collection of measures linked to specific hazards and their impacts. In this sense, within the framework of RESCCUE project, 94 adaptation measures have been gathered within a database. Furthermore, the related information (i.e. fields of the measures database) to properly characterize them has been proposed based on the conducted literature review and the suggestions of the city councils involved in the project (Barcelona, Lisbon and Bristol) according to their needs. In addition, a web-based platform has been developed in order to create resilience strategies based on the stored (and future new ones if required) adaptation measures. The adaptation strategies already planned by the three city councils involved in this project, have been created through the web-based platform. Nevertheless, some other adaptation strategies will arise along the project lifetime based on its outcomes.

However, in order to adequately select the adaptation strategies, different direct and indirect effects once they are implemented have to be taken into account. In this sense, the three key variables proposed to make decisions for the adaptation strategies selection are the related co-benefits, the services interdependence effects, and the strategies estimated cost.

Co-benefits that may occur when implementing a specific adaptation measure are considered as an essential information to be related to each measure. Besides, the importance of each co-benefit is defined to be established as a weight from zero (no effect) to ten (totally beneficial). In addition, in order to consider the services interdependence effects when defining an adaptation measure, a matrix which relates urban services with hazards has been proposed. It defines how effective the application of a measure is for certain services affected by hazards, but also how it is jeopardizing the recovery capacity of another. Finally, the estimated cost, as a key variable to decision making, is proposed to be considered once the strategy is created.
