 The Sentinel project is trying to address trade-offs between three SDGs, Sustainable Development Goals. That's SDG 2, Zero Hunger, SDG 10, Reducing Inequalities and SDG 15, Protecting Terrestrial Ecosystems. There are trade-offs between these in particular in Sub-Saharan Africa where achieving SDG 2 would require probably more than doubling food production by 2050. Now this would clearly have immense social and environmental impacts. And so the challenge is that these trade-offs are currently not normally officially recognized in the political discourse in most countries in Sub-Saharan Africa, but also that there are power imbalances between those working in the agricultural sector with the agricultural sector delivering on employment and food security and those in the environmental sector who often cannot easily explain why environmental services are also very important and ultimately required for sustainable development. And the starting point is really to get decision-makers in the countries where we work, at the Sambia, Ghana and Ethiopia, to recognize that these trade-offs do exist and that they won't go away, so we need to talk about them. So we've been using, for example, now during the first year, a process of participatory scenario development to think through where the impacts of agricultural development, environmental and social impacts are likely to occur and which impacts are likely to happen under what type of future agriculture. So the process of bringing people together, discussing these issues, not blaming each other but really having a dialogue is extremely important for that. And that is also the spirit of the project overall, its co-development of knowledge between researchers and research users, developing their capacity to do this and to develop new partnerships and new ways of having dialogues about these very contentious issues. So the Sentinel theme is highly topical and relevant at this stage because, as I said earlier, most countries have signed up to the SDGs and so it's clearly important to be aware of where these trade-offs occur and how we might eventually be able to overcome them, even though the how might not necessarily be a political solution but maybe a negotiation of objectives and recognition that there might not be always a win-win situation throughout. The other exciting thing is really to work with very good partners both in Africa and in the UK and to really have a process of transdisciplinary research whereby we bring together people from very different fields. Some of them have never worked together. They've never really worked with people who are doing habitat mapping or modeling of ecosystem services. So it's very new for all of us and we are learning a lot from it. And certainly the equitable partnership that is our ambition to achieve in Sentinel is also very exciting and very ambitious because we really try to share responsibilities in the project and to work together in a very democratic way. And for some of the partners this is a very new way of working. It's not always easy but it's interesting and we are enjoying it so far.
