Job description

Food systems across the world are facing a period of radical change, both due to the recognition of food-related environmental damage, but also due to climate impacts. Rapid change is unavoidable, but rapid transitions could help resiliency to impacts while reducing environmental harms. The Great Food Transformation suggests three main pillars for change: 1) Dietary change, 2) Food waste reductions, and 3) production changes. However, dietary change comprises by far the largest opportunity, especially in high-income nations. This Great Food Transformation would reduce the environmental damage from the food system and would also free large areas of land with climatic impacts. Reductions of biogenic methane would further have a cooling effect even in the short term.

A new project will start from September 2023, funded by an international scientific prize for work on sustainable food systems (judged by 100 scientists globally, more information here and a keynote of the work here). Two PhD candidates will be appointed at the Institute of Environmental Sciences (CML), continuing the team’s work on rapid food transitions. The two candidates will work closely with Dr Paul Behrens, Dr Oliver Taherzadeh, and other academic staff in the rapid food transition team on areas including the social impacts of food transitions, impacts on food resiliency, and climate impacts.
One PhD candidate will work on developing our modelling framework further

Key tasks:
Your will work in an interdisciplinary setting to integrate models and data from different fields (food sciences, economics, climate science, epidemiology, etc.). Specifically, you will:
  1. Perform several detailed analyses on the environmental impacts of global food systems.
  2. Help to further extend an integrated food system model with international trade flow data to better attribute environmental impacts of food production to remote consumers.
  3. Perform several detailed analyses on the social impacts of food system transformations.
  4. Analyze climate impacts on food systems and explore the resiliency of food system transformations.


Leiden University


Selection criteria:
  • You should have an M.Sc. in a relevant field (chemistry, biology, sustainability science, and/or industrial ecology), but we also consider candidates from other scientific fields.
  • Strong data management, visualization and coding skills (e.g. in Matlab, Python and/or R) are highly valued. During your MSc your thesis ideally involved handling, combining, and analysing large datasets and/or focused on quantitative sustainability analysis.

Research at our Institute/Faculty
The Faculty of Science is a world-class faculty where staff and students work together in a dynamic international environment. It is a faculty where personal and academic development are top priorities. Our people are driven by curiosity to expand fundamental knowledge and to look beyond the borders of their own discipline; their aim is to benefit science, and to make a contribution to addressing the major societal challenges of the future.

The research carried out at the Faculty is very diverse, ranging from mathematics, information science, astronomy, physics, chemistry and bio-pharmaceutical sciences to biology and environmental sciences. The research activities are organised in eight institutes. These institutes offer eight bachelor's and twelve master's programmes. The faculty has grown strongly in recent years and now has more than 2,800 staff and almost 6,000 students. We are located at the heart of Leiden's Bio Science Park, one of Europe's biggest science parks, where university and business life come together.

The environmental science research in CML is organized around two major research areas: 'Industrial Ecology' and 'Environmental Biology'. This makes CML one of the few institutes covering both the circular, sustainable economic use of natural resources and natural capital, as well as assessing the environmental impacts of economic activities on natural resources, biodiversity and natural capital. Presently, over 150 FTE (including postdocs and PhDs) are employed at CML. CML collaborates with the TU Delft and Erasmus University (Rotterdam) in the Leiden-Delft-Erasmus Centre for Sustainability (LDE-CfS).
