 I have a request, Professor Dieter Leple, Professor of Regional Urban Economics, Hafen City University, Hamburg to make his comments. Yes, not being an expert on Mumbai, I will anyhow take the risk to place Mumbai in the range of our global city, since we have already discussed. So with London and New York, it was evident this has been the comeback cities with a very dynamic, demographic and economic development. The same was with Shanghai, with enormous dynamic of economic and population growth. Berlin and Johannesburg, they suffer from a specific transition I won't discuss now, but Mexico was a very specific case. In Mexico, we had strongly expanded, or not strongly, but still expanding city in a demographic way, but a shrinking city in an economic way. And now Mumbai, despite the slow down of the rural urban migration, it's still growing in a demographic way. In Mumbai, we see an important shift to a knowledge economy as Saskia has shown. But what's very important with Mumbai, that if you look in the last 10 years, we have a strong degrees in formal employment. And we have a strong increase of informal employment, casual employment, self-employment. And this gives an enormous pressure on the government to react more or less as an employment system, not as a decision system. Which reinforces again the pressure of retreat of the state. Which reinforces again this problem of employment. So what we see is this very complicated interaction between globalization, informalization, urbanization and the more liberal regime of politics. And this leads to a strong segmentation, fragmentation, exclusion. And well, I think there's a key point now, how church we the informal economy, and I think Saskia will agree that what we see in Daravi or what we see alongside the water side is not the new informal economy. But it's a degraded form of strategies of surviving. By a strong form, we will discuss later, by a strong form of exclusion. So if this is right, there are still, as you know, as you said, I'm convinced there are still forms of this new informal economy you can find. But the question is what is the majority of these informal activities. And I think that this is your notion of formal informal sector is a very interesting interface between the two systems. But if my sketch is right, so we cannot hope that there will be the solution of this exclusion, of this segregation by focusing on the global city strategy. But we have to discuss how we can build bridges from this informal economy to the formal economy. So sanitary education will be key issues. But we also have to re-discuss manufacturing. For you know, we have this big problem of this breaking down of the manufacturing without upgrading and transforming of the manufacturing. So we have to discuss the notion, we also discuss the new urban manufacturing or other forms of manufacturing. So this I think we open up new perspectives we haven't discussed in the other urban, or other urban age cities. And I think it's a very, very interesting case study. We should take serious in its specificity and its very specific dynamics, which are strongly reinforced by globalization, but also strongly determined by the history and the specific context. Thank you. Thank you very much. Blackish. Last word. Yes. I think that we've had a really very, very interesting discussion, which just illustrates how we are in the midst of transition to higher economic growth. And I think that the comments have illustrated some of the fears. But what I would say is that it's imperative that we accelerate urbanization. And I think the point made Professor Leppley on manufacturing, that in India we normally almost never talk about manufacturing in connection with urbanization, very different from other cities. We seem to be afraid of manufacturing in our cities, but in fact it's really manufacturing, bringing manufacturing into the middle of cities with people employed in those jobs is going to make a difference. So we really have to approach this transition of faster urbanization, faster economic growth with confidence rather than fear. And I think that is what Mr. Patak illustrated. I didn't detect any fear in him in what he's doing in Mumbai. And all power to you, Mr. Patak, for going on with the confidence. We have to make our cities, however, much more people-friendly in India than they currently are. It is just not comfortable living in our cities today. And we have to make them comfortable. And people should be happy to come into the city because they're going to get jobs and be comfortable. Thank you very much. Thank you. The three main speakers and the four discussants all succeeded admirably in giving us a lot of food for thought in that session. They reacted to each other brilliantly.
