 Yes, I'm talking today about the Clearinghouse project, which is a joint project between Europe and China. And the point of the project is to look towards improving urban living conditions in both continental situations. I'm speaking today on behalf of a group of researchers, so I'd like to thank them for their contribution. The basis of our investigation is around the concept of nature-based solutions. I've put here a slide that is draws on the international union for the conservation of nature. And they say that the nature-based solution is an action to provide sustainably managed and restore natural ecosystems, etc. Address societal challenges, provide a set of tools. And I think importantly, nature-based solutions, the plural word is important here. They are not a single action, but represent many actions. I think we all know, and this is a theme that runs through conferences and seminars, workshops of this kind, is that we are urbanizing at an alarming rate. So the planet is going through a significant environmental change and that the cities are amongst the most vulnerable. The trend, all predictions suggest that urbanization will increase continuously at least until 2050, maybe beyond. Cities are the hub of global economic activity, but also the hub of global energy consumption. And as we've heard already this morning was one hopes that the tide might be turning urbanization does generally lead to a decline in the amount of green space and normally that is a consequence of the pace of development. So let's pose a question where can trees and urban forest help and it's helpful here to I think they use the United Nations Sustainable Development Goals. I've highlighted three where I think urban forestry can make a significant contribution. It likely can make a contribution to all. In terms of good health and well being sustainable development goal three sustainable development goal 11 sustainable cities and communities and sustainable goal 15, which is life on land. So, trees and urban forest how do they actually provide or work as a nature based solution. Well, that really is not stuff of NASA or the European Space Agency this is simply to say, the trees in particular deliver most of these benefits simply through their normal biotic activities, but equally through their social and economic benefits, one might call this the anthropocentric function. And so a good way to deliver these is to consider them within the realm of ecosystem services and the ecosystem services they deliver. But there are challenges out there. Historically trees and forests and urban areas have been undervalued in respect of the services they deliver to societies. You can see here a campaign that hit the international news from the United Kingdom, where through what I think we could call it an era of planning judgment. The city of Sheffield gained a very bad reputation for cutting down mature trees. In urban areas existing policies and practice for the governance management and conservation of trees and forest clearly needs to change. And although in meetings like this we hear evidence of change. It's still not widespread enough. Our understanding of different approaches across countries and continents can help in terms of mutual learning and improve the strategies we have for urban forestry. And that was the basis upon which we were granted funding by the European Commission, and more recently by the Chinese most for the clearinghouse project, looking at urban forestry as a nature based solution. So a little bit more about how we are addressing an overcoming the challenges. Well, we're working across both research and innovation. We're working in China in Europe. We're providing open access to the knowledge gained. We're trying to bring together practitioners and strategists in cities, as well as researchers in the sector. We're providing guidelines already mentioned today. Those like guidelines are something that I'll be leading on over the next 18 months or so. In terms of where we've reached so far in the project there is an innovative innovative new technology, sorry type typology, a conducting of a large public perception survey on urban forestry in both China and Europe now complete data still in analysis. There are case studies available already on the nature, nature network program, which is available on the internet. And we've already completed an important analysis of governance, institutional economic frameworks for urban forestry as a nature based solution. A little bit about the Sino European situation. What we found so far, and you will see here from Fermilab in the US, the diagram on ecosystem services, just to help position you. We certainly identified that there are scale differences. So far in our cross continental comparison we've discovered that the interventions in China on balance tend to be of a larger scale than those in Europe. And that might have to do in large measure by the fact that space is of a particular premium in Europe. And certainly, it's quite clear to us now that there is evidence to just that the China Forest City program is a global leader, when it comes to tackling urban forestry as an NBS. And in particular, we think that the KPIs, the so called key performance indicators that have been developed for that program have global resonance. What's interesting, although to some of us not greatly surprising is the cultural ecosystem services that you will see in the bottom left of the Fermilab diagram, perhaps rather stronger in the European situation, whereas the regulating services are stronger in the Chinese situation. Even the fact that clean air is a particular problem in China that is perhaps one of the least surprising findings we've come across. And I wanted to share very briefly if I have time some of the key findings. The first finding is this is that it's important that we elevate the role of urban trees above simple aesthetics reinforce their role as critical urban infrastructure and provide a clear linkage to the delivery of ecosystem services. That involves an educational role as well, particularly for urban planners to make them aware of urban ecosystem thinking. The third finding is that the concept of urban forestry as a nature based solution remains a new concept. So there is a need for knowledge and capacity building amongst all engaged stakeholders. Our third finding is that land availability for urban forestry seems to be a universal problem. It's very evident in both Europe and China. And by extension, I think we're fairly confident that this could probably be said for almost all urban situations globally. Our fourth finding is that the engagement of civil society, by which we're referring to social groups and citizens is still relatively low. In the last part, this suggests that the planning and management of urban forestry is still largely top down, rather than bottom up. And this raises clearly an issue of governance, something that I know within the European arena. There is much talk at the moment about how to step up the idea of co governance and bottom up involvement in nature based solutions as a whole, specifically looking at urban forestry on its own. Our fifth finding is that the engagement of the private sector is falling short of expectations. One minute morning. Okay, thank you the long term management of the urban forest is certainly an opportunity in this regard, in terms of increasing in the engagement of the private sector. Our fifth finding is I think particularly important that there is complementarity between different types of nature based solutions, and possibly additional benefits from the management of water and trees together for air quality and tackling the urban heat island. This leads to an important point should urban foresters also be water engineers, or water engineers also urban foresters. We've also taken a literature review, very global literature review on urban forestry as part of this project. This is what came out of it. These slides will be made available and because of time I won't spend any time on that now. On behalf of the clearinghouse project and to the funders particularly the Chinese mosque and the European Commission for their generosity and invite you to connect with us on social media. Thank you.
