Subproject 1 aims to conduct a comparative analysis of infrastructures in rural and peripheral areas in order to better understand both prevailing and innovative adaptation processes. Subproject 1 primarily undertakes the task of synthesizing the analyses of individual infrastructures in subprojects 2-8. For this, the perspective of the archetype approach is chosen. This approach enables an analysis with a medium level of abstraction, in which several recurring patterns of interaction between system elements (archetypes) are included in the analysis as equally important. 

To best represent the mixed methods primarily used in AdaptInfra, methods for integrating qualitative and quantitative data are applied, and the system dynamic approaches embedded in the AdaptInfra concept are further developed. Qualitative system models for the infrastructures under study will be designed collaboratively with subprojects 2-8 and system archetypes will be identified. This is combined with an analysis of quantitative time series data on the infrastructure condition using the method of dynamic time warping to identify archetypes of prevailing infrastructure adaptations. Furthermore, case studies of innovative infrastructure adaptations from AdaptInfra and from case studies worldwide are systematized, examined with regard to their systemic structure, and summarized into a set of archetypes of innovative infrastructure adaptations. Finally, the resulting systemic understanding of prevailing and innovative adaptations are used to develop future scenarios for alternative infrastructure developments and their conditions.
