Abstract. Universal access to the commons, such as to clean water, might be seen as a strong challenge to development as freedom. Beyond water scarcity, several regions are already suffering from lack of access, even where water is abundant. Meanwhile, climate change, overpopulation and agricultural demand are severely affecting the quality and availability of water resources. At the global level, concerns about water are tied to the Amazon Region, which contains the greatest potential water stock in the world, and which simultaneously faces the worst troubles in access and supply. This paper is therefore aimed at pointing out the role inclusive social innovations can play in mitigating the impact of growing water shortages and securing effective water use. After a first introduction to Brazil, Amazonas and Parà state statistics on water-related aspects, the research focuses on results emerging from the AguaSociAL project.
