Institute for Sustainable Development and International Relations – IDDRI

The Institute for Sustainable Development and International Relations – IDDRI ( is a non-profit foundation recognized of public interest by the French government. Based at Sciences Po in Paris, IDDRI is an independent institute for policy research, focusing on research and policy influence for sustainable development at the European and global scales. It examines sustainable development issues requiring international coordination, such as climate change, food security, future evolutions of agriculture, biodiversity and the depletion of natural resources and urban systems in the context of global change. IDDRI has three objectives: informing policy decisions, identifying emerging policy issues and creating a platform for dialogue between stakeholders (private businesses, public sector, academia and civil society) and public policy makers. As a Sciences Po Paris partner, IDDRI’s researchers are highly involved in teaching and in developing research programs. IDDRI has developed a strong international network and organized several international conferences, workshops and research seminars. IDDRI research activities are mainly concentrating on identifying technical, economic or political drivers of change and on sketching scenarios for transition toward sustainable development pathways along with the conditions required for such a change.

IDDRI is leading WP8 on Foresight exercise and synthesis of prerequisites for sustainable, resilient, efficient and fair food value chains

IDDRI is also co-leading task 5.1 in WP5 and will contribute to work across the project and participate in the iterative workshops developing the conceptual model framework.

The IDDRI Team

Dr. Sébastien Treyer

(male) director of programmes & researcher. He joined IDDRI in January 2010 as the director of programmes, and as the coordinator of the “Agriculture and Food Policies” programme. His research focuses on three fields of agricultural & environmental policies. First, he is involved in designing foresights and forward-looking processes for long-term water resources management and agricultural development at the river basin scale in Europe, the Mediterranean Basin, and Western Africa. Second, he developed research projects to analyse the use of foresights at various steps and for various levels of the protection of ecosystems in France and in Morocco. Third, he analyses the role played by scenarios as central elements of expertise for global environmental governance and agricultural development. He has been in charge of Foresight studies for the French ministry of Ecology, Sustainable Development and Energy (2002-2006), and has been coordinating the Agrimonde Foresight Study for INRA and Cirad (“Scenarios and challenges for feeding the world in 2050”, 2009). He is one of the authors of the SCAR Foresight Report n°3 (“Sustainable food production and consumption in a resource constrained world”, EU Standing Committee on Agricultural Research, 2011). Sébastien Treyer is Chair of the scientific and technical committee of the French Facility for the Global Environment (Fonds français pour l’environnement mondial [FFEM]). He is also member of the scientific council of the Seine-Normandie Basin and of the Agence nationale de la recherche’s sectoral scientific council “Ecosystems and sustainable development”. Sébastien also teaches the design and use of foresights and scenario planning at AgroParisTech and Sciences Po Paris. He will coordinate the work package on future scenarios aimed (WP8).

Dr. Pierre-Marie Aubert

(male) research fellow Food and Agricuture Policies. Before joining Iddri in 2015, Pierre-Marie Aubert had been teaching agricultural & environmental policies at AgroParisTech, the Paris Institute for Life Sciences, Agronomy and the Environment. Trained as both a political sociologist and an agronomist, his research covers two inter-related fields. He first works on the interactions between agriculture value chain governance, environmental policies and food security issues at the landscape, national and international level (Palm Oil, Soybean, Rice, Milk and Grain). He also works on scenario exercises at both the landscape & the national level especially in the field of agricultural development. The aim is to reflect on possible transformative pathways of the agricultural sector to improve its impact on both food security and the environment.

Dr. Yann Laurans

(male) head of biodiversity programme. He is a senior environment and natural resources economist. He was, during his first ten years, a research manager in a consultant and environmental policy research firm. He was then the chief economist of a water policy public body. And since 2008 he is a senior researcher in environmental economics, a research associate of IDDRI and more recently the head of biodiversity research team at IDDRI. As chief economist and as a consultant in local environmental strategies, he has either conducted or participated in sustainable policy scenarios and foresight exercises. He is also experienced analyst of relations between agriculture and the environment, and more specifically between wetlands and farming. His current assignments are related to sustainable fisheries scenarios in the Indian Ocean, analyzing soybean value chain with respect to forest conservation and economic instruments for environmental conservation.

Dr. Marie-Helene Schwoob

(female) research fellow Food and Agriculture Policies. She is an agronomist and political scientist, who conducts research on sustainable agriculture with a specific focus on the sociological and political aspects of the transformation of agrifood systems. She has been coordinating the Agricultural Transformation Pathways Initiative at Iddri and Rothamsted research, an international initiative which supports countries in the development of national transformation pathways towards economically, environmentally and socially more sustainable agriculture and food sectors. The methodology promoted by the initiative, which she has been working on with pilot countries (China, Uruguay and the United Kingdom), puts special emphasis on the development of shared visions of a desired future and on backcasting approaches.

Dr. Renaud Lapeyre

(male) research fellow Biodiversity and Ecosystem Services. Renaud Lapeyre is the coordinator for the INVALUABLE project, an ERA-Net EU- funded research programme which analyses the role, potential and limits of market-based instruments for biodiversity conservation (see This includes the study of payments for ecosystem services (PES) such as CAP agri-environmental schemes, biodiversity offsets (BO), but also certification schemes as well as the regulation of value chains through taxes and command-and control approaches. Field work was so far conducted in Indonesia, Uganda, Sierra Leone and Côte d’Ivoire, where a number of environmental issues are linked, at least partially, to agricultural commodities traded globally (palm oil, cocoa, rubber).
