 So here I want to introduce a very typical case in Beijing, that's Beijing Aforestation Project. This project is launched for create a more wealthy city. Before we start, I want to introduce why the Beijing government launched the inner city Aforestation. So the plant area in Beijing, that's include the entire city center. And most population, they are focused on this area, nearly like 16 million people. But for the urban forest, they have limited urban forest. So in 2011, the plant area has like more than 30% less than the forest coverage in mountainous area. And also there has a very big problem about the forest patches, that's more and recommended. And also all these status of forest or urban forest and trees, that's filled to meet the citizen's demands in Beijing. So in 2012, the government in Beijing have launched the Beijing Aforestation Program. So with the aim of create nine green veggies and also create green belt, two green rings and also multiple green corridors, they start the Beijing Aforestation Project since 2012. And until now they are still doing this project, implement this project. So I would focus on the main actions the government they already implemented. The first one is reconnected the pre-existed urban forest patches. For example, along the roads and the rivers, they create, they plant more trees along them. And also the restoration, they're restorating the wetlands, centipedes and also some wasteland in the urban and peri urban area. The third action is they're turning green to green. For example, they planted trees in high urbanized area, like the city center or city core. They have created their pocket urban parks and also some very small urban green space or green gardens. The fourth action is to create more forest wetlands parks in peri urban area. Because in that area they have bad background of cheese and also forest. So they just construct more parks in the peri urban area. So this can help to create more recreation space for the citizens. The last action is the recycle of construction waste, such as they use the construction waste to create landscape accessories and also to the waste the construction waste is used to create the path in the parks. And here I want to show the spatial distribution of the new forestation. The red color is the red color shows the new forestation that was planted in 2018 to 2020. And the green color shows the previous forestation sites, that's from 2012 to 2017. And here I want to say in the past nine years, the government in Beijing have created, have planted new forestation. The total area is 1.78 million hectares. So you can see the new forestation area they include, the new forestation area they include every year. So I also want to introduce the key outcomes for this project. For example, the first very impressive outcome is increased the urban forest area in high urbanized region, especially in the plant area in Beijing. You can see the data here for the Beijing city, the forest coverage has increased more than 6%. And in the plant area the forest coverage has increased like more than 15%. Another side, these improve the ecosystem surveys provided by the urban forest and trees. For example, it can help to mitigate the urban heat island and also create more space for the citizens for their recreations and also improve the citizens awareness. And then it also can help to improve the biodiversity conservation. So our field work has shown that the number of the butterflies and also the birds has increased in the last nine years. And also the last one is restoration the soil quality. Another side, the urban forest also help to promote the social economy. For example, they create more green jobs. For example, the new forestation, they need management. So more people they can to help to do some management, forest management work and some there in the, and also for the tourism. For example, our speakers invited our speakers also mentioned that the green call, the green care and also the nature school, all this has promote the local tourism that's provided by the urban forest and trees. The last one is this big inner city forestation also encourage more public and private investment because they can invest in the tourism. They can build more like restaurants or hotels or some other infrastructure in some big urban forest parks. So they can also get some money back from this kind of project. Because our topic is about real estate city. So for me, I think the real estate city is not only focus on how to improve the GDP. It is more, it is to be include more like help people to improve their life quality and also how to use urban forest and also urban forest and trees as a way or a tool to create more values, economic values. So in our future and also in this meeting, I would suggest some more actions that we need discussion or maybe we can add more in our future. The first one is complete the governance system for inner city forestation, both bottom up for government leading system. The second one is more research actions are needed for the whole cycle of such kind of inner city forestation projects. Oh, we say we set the urban forest as nature-based solution projects. For example, we need to multiple guidelines for all standards for for different for planning and the design and also for implementation as well as management. And also we need use friendly models or universal models to evaluate the ecosystem surveys or ecosystem or values that provided by the urban forest and the trees. The last one is we also need some tools to use citizen science, for example, use citizen science to monitor the urban forest to monitor this kind of such kind of inner city forestation project. The third one is just as similar as that, how to convert the urban forest to a project that we got as an investment project. Now when we say something about the urban forest or forestation, most people they will consider about, it will cost a lot of money. So we need more like these business models to promote such kind of inner city forestation project. The last one is we can see when cities there can they can impact each other. So more cross-city or cross-region cooperation on the urban forest project are needed in our future. So all of these, that's all I want to introduce to you all. If you have any questions, just feel free to connect me. Thank you.
