I am a Geographer studying impacts of global climate change on agriculture and food security. Here you will find an overview of my research and research data sets that I have developed or helped to develop.
Welcome to my blog
Below you will find examples of my research and ideas for solutions to global challenges that I believe our societies will continue to face in the coming decades. As a Geographer I am interested in how people and the environment interact and influence each other. Most of my research is about global climate change and its impact on agriculture and food production and about smallholder agriculture in Africa and Asia and food security.
Agricultural diversification and crop yield stability
Crop yields in East Africa, for example in central Ethiopia are low and year-to-year variability is large because of poor soils, harvest losses and high variation in water supply. Spreading the risk by diversifying production could be potential solution for...
Climate change impacts in the Nile basin
The Nile basin is one of the major agricultural production regions in Africa. Climate change can increase the risk of heat stress for crops and shorten the growing season and the impact differs between double and single cropping systems.
Trends in Australian midlatitudes rainfall
Annual and seasonal rainfall are important drivers of agricultural productivity and profitability in Australian agriculture and various climatological and synoptic drivers influence rainfall patterns in Australia’s diverse climate.
Agricultural Diversity and Food Security
Whether to diversify agricultural production or not can be a challenging decision for a farmer. On-farm diversification is often promoted as a beneficial strategy to adapt to climate change, increase food production sustainably or as a solution to food insecurity. But...
Global vegetation and crop modelling
Computer modelling is an important research tool to conduct virtual experiments. For natural and agroecosystems for example, to understand interactions between system elements and predict outcomes relevant for human societies. LPJmL is simulating environmental change in the terrestrial biosphere.
Adaptation to climate change in sub-Saharan Africa
A farmer’s practices change constantly in response to changes in the environment. Change in the way a crop’s growing seasons is managed is one potential strategy. We here demonstrate how effective two example adaptation strategies can be in avoiding negative impacts from increasing temperatures and changing precipitation.
