L & F Lab

The Land use and Food systems Lab at the University of Edinburgh

The Land use and Food systems (L&F) Lab is an interdisciplinary group modelling global food systems. Combining expertise from ecology, engineering, economics and social science, we apply state-of-the-art models to understand the social, economic and ecological interactions and trade-offs in globally interconnected land use systems. We are a core part of the international collaboration that has produced the Land System Modular Model (http://www.landsymm.earth), and conceived, designed and implement the PLUMv2 model that is a central part of LandSyMM.

Current projects include:

  • “TRAnsforming the DEbate about livestock systems transformation (TRADE)” funded by UKRI under the Transforming the UK Food System for Healthy People and a Healthy Environment Programme, 2022-2025
  • “Co-designing Holistic Forest-based Policy Pathways for Climate Change Mitigation (ForestPaths)” receiving €6M funding from EU’s Horizon Europe programme, 2022-2026.
  • Wellcome Trust project “Reducing meat intake to mitigate climate change and improve health”, 2020-2022

The research group also supervises students’ dissertations.

We welcome proposals for engaging with your research projects, including supervising research students. Please have a look at the previous research projects and papers below, as well as the topics considered by current and former students.

Research Staff & Students

Dr Peter Alexander

Senior Lecturer

Peter leads the group and his main interests are the interactions within national and global food systems and land use, combining social, economic and environmental considerations. His research applies data and computationally intensive techniques, such as agent-based modelling, to improve understanding of the human-natural interactions including behavioural aspects of decision making. Prior to his academic career, Peter ran a livestock farm in Scotland and before this worked as a quantitative financial modeller in investment banks.

Dr Frances Warren (formerly Cossar)

Teaching fellow

Frances is an economist with a diverse background working on national budgets in Rwanda, global manufacturing value chains, agricultural mechanization in Ghana, and now focusing on the environment and socio-economic implications of global and UK food systems. She also enjoys the challenge of teaching environmental economics in the department, running up Edinburgh’s hills, and some amateur musical pursuits.

Dr Joe Kennedy

Postdoctoral Researcher

Joe has a research background in theoretical physics and cosmology with a focus on developing methods to test competing models of cosmic acceleration. After completing his PhD at the University of Edinburgh, he moved to the University of Geneva to pursue research in the use of artificial intelligence methods to test fundamental physics with cosmological data. Motivated by the urgent need to tackle the interconnected challenges of climate change, public health and biodiversity loss he has now switched fields to put his experience in physics to use in more terrestrial applications. With support from the Wellcome Trust, together with Peter Alexander and Lindsay Jaacks (Global Academy of Agriculture and Food Security), he is now developing a simulation model to assess the impact of red meat taxes and health and environment warning labels on red meat products on the incidence of chronic diseases in the US.

Dr Roslyn Henry

Postdoctoral Researcher at University of Aberdeen

Roslyn’s research interests lie in exploring the interplay between food security, land use and biodiversity. Her background is in ecology and evolution and she completed her PhD at the University of Aberdeen.   After spending years working on PLUM as part of the group has returned to University of Abereen, but contiunes to work with the group.

Dr Juliette Maire

Researcher at Trinity Agtech

Juliette has just completed her PhD at the University of Edinburgh on novel approaches to capture spatial and temporal variability of nitrous oxide emissions from grazed grassland in the UK and in Ireland. Prior to her PhD, she worked as an engineer and research assistant in Australia, France and Scotland on topics from monitoring forest phenology using an automated camera to modelling European crops rotation to assess the cost efficiency and environmental benefices of adding more legumes into the rotation.  Juliette has a background on the sustainable development of agriculture and agroecology.  She contiunes to work and publish with the group but has now moved to work at Trinity Agtech.

Magnus Merkle

Former Research Assistant and now PhD Candidate at Norwegian University of Life Sciences.

Magnus has studied Sociology, Politics & Economics in Germany and Ecological Economics in Edinburgh. He worked on the interrelations between market power and food system resilience in the RUGS project as well as on the quantification of socioeconomic scenarios for climate impact research in the UK SSP project.  However is now doing a PhD at Norwegian University of Life Sciences, although still working and publishing with the group.

 

Bart Arendarczyk

PhD Candidate

As part of his PhD, Bart is investigating options for land based mitigation of climate change using a global land use modelling framework (PLUM-LPJ-GUESS). This includes looking at trade-offs between food security, carbon emissions, protecting biodiversity, and maintaining ecosystem services.

Tamsin Woodman

PhD Candidate

Sustainably increasing global food production while preventing negative impacts on biodiversity poses a major challenge to society. Current ecological models predict the effect of climate change on biodiversity at a range of spatial scales, but they do not account for the impact of land use change. Tamsin’s PhD aims to integrate ecological and land use models to investigate the combined effects of land use and climate change on the spatial dynamics of pollinators and crop pests, and potential feedbacks on crop productivity and future land use scenarios.

Kirsty Blair

MScR + PhD Candidate

Kirsty came to Edinburgh from the University of Leeds, where she completed an MEnv in Sustainability and Environmental Management. She also spent a year at the University of Adelaide in Australia learning about indigenous culture and making the most of the hiking and outdoor activities on offer. She has recently begun her 1+3 doctoral training programme. Her research will be investigating the competing socio-cultural and environmental narratives around livestock consumption in different cultural contexts, and the role that relational values have to play in these narratives.

Aimen Sattar

PhD Candidate

Aimen is a PhD candidate at the Global Academy of Agriculture and Food Systems, focusing on modelling the agricultural system in Egypt. He will develop a model to investigate the interaction between water resources, farmer cropping decisions, and government policy. Aimen has an engineering background, having previously completed an MEng in Mechanical Engineering and an MPhil in Engineering for Sustainable Development, and worked as a subsea design engineer. Before joining the University of Edinburgh, Aimen spent 4 years working in the humanitarian sector, helping to deliver medical projects in Africa and the Middle East.

Kaela Connors

PhD Candidate

Kaela’s PhD research will focus on modelling the global environmental and health impacts attributed to food system transition scenarios in the UK. Prior to joining the School of Geosciences and Global Academy of Agriculture and Food Systems, Kaela received her Master’s of Science degree in Global Health and Population from the Harvard T.H Chan School of Public Health. She is broadly interested in studying the intersection between sustainability, food system transitions, and health with a focus on equity. Before her master’s, Kaela spent three years working at the National Institute of Public Health Mexico (INSP) in Mexico City and at the UN World Food Programme in Panama City where she identified her interest in social determinants of health, climate change, and food systems. Her B.A. degree is from the University of California, Berkeley in Political Science and Environmental Economics.

Alexander Vonderschmidt

PhD Candidate

As a PhD student at the Global Academy of Agriculture and Food Security, Alexander will focus his research on modelling the impact of meat reduction on population and environmental health. Alexander completed his master’s degree in nutritional epidemiology at Cornell University in New York (USA) where he also earned his registered dietitian nutritionist (RDN) credential. His past research has centered around using epidemiological models to explore longitudinal diet—disease associations. Alexander also holds a BS in dietetics and a BA in French from Kansas State University (USA).
