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.

Farm Diversification in South- and Southeast Asia

Farm Diversification in South- and Southeast Asia

South and Southeast Asia host more than half of the world’s undernourished population. By diversifying can increase dietary diversity. Especially smaller farms can improve dietary diversity through farm diversification.

Agricultural diversification and crop yield stability

Agricultural diversification and crop yield stability

Crop yields in East Africa are low and year-to-year variability is large.
Generally is farm diversity higher in cooler and wetter areas with higher temperature variability. We find that crop diversity positively affects temporal yield stability.

Climate change impacts in the Nile basin

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

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.

Global vegetation and crop modelling

Global vegetation and crop modelling

Computer modelling is an important research tool to conduct virtual experiments. It is essential to understand interactions between system elements and predict outcomes relevant for human societies. LPJmL is simulating environmental change in the terrestrial biosphere.
