 The world of water is going through major transitions. We have some serious global change pressures that are affecting the way in which we manage water, particularly in cities. It's very clear that the way in which we've managed water in the past is not sustainable. And so we have to look for new ways of doing more with less. So IWA is a very interesting association. It combines academics and researchers and inventors with practitioners. So IWA is one of its primary roles is to maximize technology transfer between innovation and practice. And I think these types of events is where we bring together those different types of stakeholders. And this is where we can see the opportunities for some of the innovation to be transferred into practice. Also, IWA has a global outreach. And so what we're able to do through a Congress is we can bring together experiences from different parts of the world and through discussion and discourse, we're able to see what best practices from around the world can be implemented elsewhere. So it plays two very important roles. One is to maximize the transfer of innovation and research and invention into practice. And the other is to share best practice from around the world so that we can try and maximize the implementation of sustainable water management around the world. The Congress covers the entire water cycle. So we have sessions here that look at water resource issues in terms of the big water cycle at the basin level. What are the challenges in terms of water availability and water management at that sort of big picture level? We then zoom in to the challenges that face cities. And we first of all start by understanding how a city sits within the broader catchment or river basin. How does it interact with water for food production, water for industry, and of course water for the environment? So we have sessions that try to understand the interrelationships between the different water sectors. And then we zoom into the city directly. When we start to ask ourselves, you know, how are we going to manage this growing demand for water that's going to take place in cities because of rapid urbanization? And we look at how to analyze these problems from a systems perspective and then try and understand specific technologies that can be deployed in order for us to provide a more efficient approach to water management. And then critical to all of this is people. So IWA also has a sessions which talk about stakeholder participation, about multi-institutional and collaborative platforms so that discussions and dialogues at the city level can take place that then inform the types of approaches that we provide and the solutions we provide. So it's a very holistic and coherent approach. And so it tries to address the problem of water management at many, many different levels.
