The environment is a common good. Thus, environmental management affects the citizens: measures are often implemented with public funding, and they can impact citizen’s daily life. So it is for urban water management (UWM). Urban water management options differing from the status quo exist. Those alternative options may imply the installation of different toilets (e.g. with urine source separation) or more local treatment (e.g. in the building itself). For those reasons, decision-making about UWM should be transparent and participatory. Multi-Criteria Decision Analysis (MCDA) is a method that enable making complex decision, characterised by difficult trade-offs. However, most often only a few tens of stakeholders, usually experts, can take part in the process.
The main objective of Edanaga project is to enable laypeople and/ or citizens to take part in the MCDA process. Serious games and gamification are promising: as engaging media, they could spark interest for a priori unattractive topics, maintain attention in tedious tasks, and facilitate learning. To date, few studies have thoroughly tested those hypotheses. During the Edanaga project, we wish to (1) test and improve an online survey prototype that enable citizens to express their preferences about the complex trade-offs, (2) use this prototype to learn about what the Swiss population finds important for the UWM, and which options she would prefer. In addition, we will evaluate existing serious games that would be useful for problem structuring and exploring the whole range of possible options.
