User-driven design of decision support systems for polycentric environmental resources management

- Environmental management may involve polycentric governance arrangements.
- Decision support for such contexts needs to meet diverse user requirements.
- A user-driven approach is proposed that involves actor and decision making analysis.
- This is combined with co-design methods from Human-Computer Interaction research.
- The result is more tailored decision support for users with different experiences.

Open and decentralized technologies such as the Internet provide increasing opportunities to create knowledge and deliver computer-based decision support for multiple types of users across scales. However, environmental decision support systems/tools (henceforth EDSS) are often strongly science-driven and assuming single types of decision makers, and hence poorly suited for more decentralized and polycentric decision making contexts. In such contexts, EDSS need to be tailored to meet diverse user requirements to ensure that it provides useful (relevant), usable (intuitive), and exchangeable (institutionally unobstructed) information for decision support for different types of actors. To address these issues, we present a participatory framework for designing EDSS that emphasizes a more complete understanding of the decision making structures and iterative design of the user interface. We illustrate the application of the framework through a case study within the context of water-stressed upstream/downstream communities in Lima, Peru.
