I do research on and teach about sustainable food production and sustainable land use from many different angles. These include to assess the environmental impact of different foods using life cycle assessment (LCA), to calculate the climate impact and land use associated with different types of diets and comparing environmental impacts of different farming and food systems. I also work in many interdisciplinary projects where we look at the economic and information policy instruments for more sustainable dietary patterns and how more sustainable and healthy food ingredients can be produced and processed.
I also work 20% at the Centre for Organic Food and Farming (EPOK) with the research synthesis and research communication. I am also associated to the Food Climate Research Network at Oxford University.
I am responsible for two courses in Life Cycle Assessment (LCA):
- Energy and life cycle analysis, 5 credits at the Energy Systems Program
- Life cycle assessment for environmental and water technology, 5 credits, at the Environment and Water program
I also give lectures on the topic of climate and environmental impact of agriculture and food production at SLU, Uppsala University and Karolinska Institutet.
What is sustainable agriculture? With Klara Fischer and Elin Slätmo, SOL
This project highlights and problematizes the concept of sustainability in Swedish agriculture. We put sustainability issues in Swedish agriculture in relation to the role of agricultural in the food chain. We also examine how the sustainability assessment frameworks for agriculture can be used in Swedish agriculture.
Effects of a climate tax on food and ways to re-cycle incomes. With Sarah Säll and Ing-Marie Gren, Depart of Economics and Emma Moberg, ET
The reduction in greenhouse gas emissions and tax revenues from a climate tax on food is calculated based on how the tax affects consumer demand for different foods. The study will analyse 1) the distribution effects (how the tax affects high and low-income groups), 2) changes in nutrient intake, 3) the impact on the profitability of Swedish farms and 4) other environmental effects of the tax (acidification, eutrophication, biodiversity etc.). It is further investigated how the revenue from the tax can be used to counteract negative effects of the tax e.g. by supporting the preservation of pastures if the tax leads to a decrease in the domestic production of beef.
Innovative food from legumes for increased resource efficiency in the food system With Georg Carlsson, SLU Alnarp and Cornelia Witthöft and Andreas Stephan, Linnaeus University
The aim of this project is to develop climate-smart and protein-rich food products containing domestic legumes (e.g. beans, lentils, peas), to increase the food system sustainability and stimulate a growing bio-economy based on novel, attractive and health-promoting foods. The project objectives are to: 1) identify strategies for incorporating grain legumes suitable for cultivation in Nordic climate into the Nordic diet, 2) develop new legume-based cropping systems that rely more on ecosystem services and less on fossil resources, 3) investigate effects of processing techniques on the nutritional quality of novel legume-based foods, 4) assess the economic, environmental and social sustainability of the production of foods based on domestic grain legumes compared to imported raw materials or meat, and develop decision support for handling trade-offs in the development of more climate-smart food systems. The project applies trans-sectorial collaboration among scientists, food industry, regional councils, farmers and consumers.
I hold a MSc in Engineering Physics from Uppsala University. After graduating in 1999, I worked for ten years in the IT and telecom industry with product and project management. I began my doctoral studies at SLU in 2008 and in 2013 I defended my thesis Analysing the carbon footprint of food - Insight for consumer communication.
I am the co-supervisor of the PhD-students Emma Moberg and Johan Karlsson. I also supervise several master students.
