Dr. Delphine Deryng

Guest Researcher
Towards sustainable and climate-resilient food production systems


  • Food and nutrition security
  • Research-policy-practice nexus
  • Climate-smart landscape


"Working at the science-policy interface, my research aims to identify solutions for developing sustainable and climate-resilient food production systems. IRI THEsys offers an exciting interdisciplinary environment to broaden and enrich my research ideas and methodological approaches." Delphine Deryng

Delphine Deryng is a Climate Policy Analyst at NewClimate Institute, where she leads research and analysis focusing primarily on national and international climate policies in the agricultural and forestry sectors, and their alignment with the Paris Agreement and the sustainable development goals (SDGs) of the UN 2030 agenda. Delphine is is also a Lead Author to the Sixth Assessment Report of the IPCC Working Group II, Chapter 5: “Food, fibre, and other ecosystem products”. She possesses extensive knowledge in the fields of climate change adaptation and mitigation, food and nutrition security and global agroecosystem modelling, as well as expertise in scientific capacity building and stakeholder engagement.

Before joining NewClimate in May 2020, Delphine worked as a researcher at the Leibniz Centre for Agricultural Landscape Research (ZALF), and earlier, as a scientific adviser at Climate Analytics, a climate policy and science institute supporting the Least Developed Countries and Small Island Developing States in the UNFCCC process. Delphine has previously held research associate positions at a number of international institutes in the USA, UK and Canada, including the National Aeronautics and Space Administration Goddard Institute for Space Studies (NASA GISS), the Earth Institute at Columbia University, the Grantham Research Institute on Climate Change and the Environment at the London School of Economics and Political Science, and the Tyndall Centre for Climate Change Research at the University of East Anglia, where she completed her PhD in 2014. Delphine also holds a Masters in Geography from McGill University (2009) and a Masters in Cosmology from the Université Paris Diderot (2006).

Since December 2018, Delphine is a guest researcher at IRI THESys.
