 Good morning, Rebelle. Good morning, Lyonna. You have been researching tropical forests for more than three decades now. They probably look very different. What has changed, in your opinion? It's not that the forests look different. It's the way we look at the forest that is different. The forest, the all-growth primary part has probably been reduced since the last 30 years. There is more secondary forest, but it's more the look at the society as a forest that has changed. When I started my career, it was still much more a look at the forest as producing timber or goods. And then we have had an evolution in going more into ecosystem services, carbon storage, but water biodiversity. So I would say that it's more the societal view and demand on forests that has changed rather than the forest by themselves. So you have always had an interest in biodiversity, and forests contain about 50% of that biodiversity today. What should be the priorities there for scientists and researchers? Well, I think these are two priorities, I think. One is we need to preserve as much as possible the area of forest that is still intact, that has been untouched. And untouched doesn't mean that there is nobody inside or people are not using it. But we should avoid making industrial use of these and try to keep them as much as possible. But more importantly, we should recognize the role of secondary forest or log-over forest in terms of biodiversity. There is considerably more biodiversity in the log-over forest than in oil palm plantation. So I think it's important because people have too often the tendency to consider this secondary or log-over forest as degraded. And because they are degraded, you can convert them in oil palm, pasture or rubber plantation. I think that's very important because now this area of log-over secondary forest is bigger than the area of primary forest. And there has been a growing movement to take a more holistic approach to landscapes. Forests inevitably play a big part in that. What do you see as the role of forest in this new landscape approach? For the same reason that there has been a change in the way society is looking at forest, the way that forest research or forestry has become broader than what it used to be. And it's part of the same trend. People have realized that Nc4 was instrumental in that that a lot of what so-called forestry problems are in fact not forestry problems. They are agricultural problems or they are socio-economic problems but not linked to forest itself more to the other sector. So that we had a role when I started Nc4 research program on underlying causes of deforestation. That was at the time pretty new, I mean, so going beyond the sort of direct impact of human activity. So I think that forest are central in this whole issue of the landscape approach. But they are not the only part so that means that we really look at the landscape as a mosaic of various use of various intensities. I think where forest play a big role but where it is very important to consider also the interaction with the other sectors. Can you talk about how the C4 strategy and priorities have evolved over time since you've been here? It was created in 1993 and when it was created there were six people in the organization. And the first, it was created with the idea of the main problem was not a technical problem, it was a policy and human problem. And so it was created with this idea of we are going to really look at influencing policies in terms of the way forest are managed. And then the first C4 strategy was in fact developed in 1996 and this first strategy was mainly continuing this initial idea of looking at forestry issues. But forestry in a sense of a relatively narrowed perspective. But in terms of what are the policies that influence or do not influence forest and we had the limitation at that time of looking at the humid tropics and for the dry tropics in the Miombos and Bézi area. So that was the first strategy. Then it evolved and then in 2008 there was a new strategy that was developed which gave much more focus in terms of the climate change agenda, the importance of mitigation and adaptation. And that already started broadening the concept of forestry. And then the new strategy which is the one in 2016 to 2025 which is really putting forestry as a centerpiece to achieve the sustainable development goals. So we have moved to someone which was something like different to the classical forestry research organization, but still very much focused on forest on something which is much broader and an answer to the all sustainable development goal questions. And how has C4 made a difference in your opinion? In many ways I mean we were probably the first to put this idea of extra sectoral importance, this initial work on the criteria and indicator for sustainable forest management. We became the go-to place for this whole issue of forest and climate change. We are now making good progress in having the non-forest sector considering the importance of forests for food security and nutrition, which was something that was not really clear to the mind of the people before. They understood that forest will provide goods and services but they did not understand the importance of forest for agriculture or the importance of forest or livelihood of people. What are your priorities for C4 going forward? Well my priorities I mean sort of you are the sort of the very short term priorities is probably ensuring that we have a good launch of the GLF in Bonn in December. Having a consultation with the staff to get their feeling of what should be done, what we need to be done. We have also a meeting of the Board of Trustees in November so these are sort of the immediate priorities. My long-term priority is that it's really to put C4 on a gross trajectory and to make sure that we continue to deliver the relevant research capacity development outreach and engagement to change the way forest and forestry is perceived and to ultimately very, very making the world a better place. And the Global Landscapes Forum which is led by C4 has just received funding for the next five years by the government of Germany. How do you see this platform evolving and how can it make a difference? It's not like if it's starting now, it's the result of a long evolution from the forest day time to the first global, what we can call the first avatar of the Global Landscape Forum and then we are going to do something which is more than a very nice significant event per year but more I think creating a platform. The overall goal of the new Global Landscape Forum which is about reaching one billion, it's really about having a transformational change in the way we conceive landscape and the use of the resources that are linked to the landscape. And you have had a very long career spanning many different continents. It might be difficult to pinpoint one moment but can you recall a time as your proudest career moment as a scientist? For me the most satisfying moment is when we got our first PhD student successfully defending his PhD in Congo, in Kisangani. And that was really the result of a long difficult effort and that was showing that it can be done. You can have people doing good doctoral thesis in Congo and there was capacity. It was probably if I look at the period between 2005 and now one of my most, where I was the most proud and the most happy. Wonderful. Thank you so much.
