In my research I am interested in the linkages between agriculture and climate change, with special focus on the need for adaptation.

Climate vulnerability and adaptation in Nordic agriculture

Agriculture is generally sensitive to changed climate conditions. There are many various methods to assess vulnerability, both qualitative and quantitative. In my research I analyse and develop methods to assess agricultural vulnerability to climate change in the Nordic countries.

Climate change is often discussed in terms of being beneficial for agriculture in Northern European. The projected longer growing season, sufficient precipitation and higher mean temperature are expected to result in increased production possibilities in Northern Europe. Various climate- and policy related factors, however, limit these opportunities. Climate adaptation is therefore needed both in terms of reducing vulnerability but also in taking advantage of an increased production potential.

Vulnerability assessments and geovisualization

Research on vulnerability theory is under constant development. There are many definitions and conceptualizations and that has resulted in many various methods for analysing vulnerability. In my research, I analyse and develop vulnerability assessment methods in order to get a better understanding of the factors that contributes to climate vulnerability in Nordic agriculture. Geographic visualization, geovisualization, is useful when representing and analysing spatial data and is therefore useful for vulnerability assessments containing spatially explicit information. Geovisualization is, in my research, used in a tool to interactively assess vulnerabilities instead of giving static index. With geovisualization, spatial multi-dimensional data can be represented and this opens up for discussion on complex problems such as climate vulnerability. If geovisualization contributes to discussion and increases understanding of the climate vulnerability problem it may facilitate knowledge on needed adaptation response actions.

Lecture from European Researcher's Night

Agricultural vulnerability to climate change

Climate change is not in the future – it is happening already. Lotten Wiréhn‘s 15-minute presentation provides an insight into how food production is impacted by a warmer climate and more frequently occurring extreme weather. Her research area is how climate information can be made more useful in underpinning decisions on adaptations in agriculture. (The video is in Swedish, but it has English subtitles.)
