This project relies entirely on open-source data. As a result, we spent countless hours searching the internet for relevant data for each city. In doing so, we discovered that many countries and cities keep their data inaccessible to the public.

We hope this project highlights how making water-scarcity-related data openly available could significantly improve public understanding and potentially lead to better water management outcomes. Access to such data makes it possible to see how different interventions and campaigns have affected cities similar to your own, which we believe is highly valuable.

In addition to the lack of available data, only six urban case studies were analysed, which limits the generalisability of the findings. Although the selected cities represent diverse contexts, they cannot capture the full spectrum of water governance challenges worldwide.

Future research could include more cities, especially from underrepresented regions, and build on the foundation established by this project. Over time, this work could be expanded into a large and diverse platform for understanding urban water governance.

While the project highlights relationships between interventions and water related outcomes, it cannot establish direct causality. Changes in water consumption, reservoir levels, and water stress may be influenced by multiple factors occurring simultaneously, including climate, economic development, population growth, and policy changes.
