 And on an annual basis, it may not rain more than say decades ago. But on an hourly basis, you have vast differences. So it's much more intense, much more local, much more both in time and in space, much more heavy if you like. How to deal with these peaks, these increasing peaks, this is one of the research issues that we do. Can we temporarily store, can we avoid flash floods in cities, can we retain the floods for some time and then indeed later on slowly release it? Can we use the excess rainfall to replenish the submerged aquifers for groundwater? These are the issues that we are researching in various places in the world. Population growth, we feel, is a major driver at the reason why we had these mega cities in various deltas around the world growing and growing. And then the water supply for people and the protection level becomes an issue. So population growth is probably the main driver, also causing climate change. And it's being recognized now. It's been, I would say, noted by researchers decades ago that this could happen. But it's been ignored or seen as natural for some time. Now it's recognized that there are feedback loops and that we have to address the issue one way or the other, whether it's Singapore in an urban environment or whether it's the Netherlands in a more, more, more polder lowland setting, or the UK for that matter, or the Mekong Delta, which is very similar to the Dutch Delta, it's now worldwide. I would say we largely build on the expertise that has been developed and is being developed in the Netherlands, and we tailor it also to other parts of the world. And so we work together with colleagues from Delft University, from Delta as a research institute from the Dutch government, ministries, public works, environment, notably, to come up with solutions that, say, would be applicable in many parts of the world. The research that's being done is, I would say, still at the forefront, and there's a large interest in many, many countries to learn from our lessons, say, and our experience and to take it further and to apply it in their own country, whether it's Vietnam or China for that matter, or Brazil or Ecuador or the United States.
