The work has consisted in developing a preliminary institutional analysis to identify aspects related to decision-making processes, intervention strategies and Mexico City’s priorities. Likewise, progress has made in researching and identifying key actors capable to characterize the complexity of experiences related to socio-hydrological risks and their accompanying responses. With the objective of gradually enhancing the interactive and iterative participation of key actors, the process design involves three phases:
Phase 1. Information/Socialization: this phase consists in presenting the project, inviting possible collaborators and sharing information. This implies three types of interactions: a) strategic reunion with involved actors, b) site visits and c) semi-structured-interviews (informant type).
Phase 2. Consultation/Cooperation: This phase requires a deeper interaction degree to obtain key actor’s mental models on water issues perspectives (flooding, scarcity, contamination, etc.). This phase consists in developing: a) semi-structured-interviews (mental model type) and b) external workshops with local communities and social actors in the study area. Phase 3. Collaboration: This phase presents the higher degree of participation. Thus, the interactions were designed for LANCIS’ decision theater. The objective is to foster social learning and enhance participants’ involvement through participatory methods. Workshops and collaborative reunions were held at LANCIS’ decision theater during this phase.
