Again, there are a lot of questions, but I'll try to be quick.
Yes, absolutely, multi-sectoral, I think, is key in getting these done for the various strengths and thought processes that the different sectors bring. One of the reasons we initiated the Future Cities initiative was that we're finding that it's really not possible for one sector to act on its own. By building these kinds of collaborative infrastructures for this kind of work, we think that the quality can be much better. It's necessary for funding, but it's also quite valuable because of the strengths that each sector brings.
Many cities have fantastic innovations, but two of the cities where I think they come together really well in ways that are examples for us are Barcelona and Copenhagen, where there is a very strong, collaborative infrastructure to bring multiple domains and public, private, and civil society bodies together to invest in and pay attention to. Of course, there's the layer of the European Union, as well, in those cases.
Participatory City, in London, which I mentioned, is another great example of that, where, again, it's a mix of public, philanthropy, and some private sector funding there.
I'll stop there.
