Christian Siderius

Research Fellow

Christian Siderius is a Research Fellow at the Grantham Research Institute. He studies people’s adaptation strategies to climate variability and uncertainty, applying economic concepts like flexibility and diversification. He works with Declan Conway on the El Nina project, studying the impact of this years’ El Nina on SMEs in Central and Southern Africa, and on the UMFULA project which focuses on decision making under uncertainty in the same region.


Christian holds a Masters degree in hydrology from Wageningen University in the Netherlands and a PhD degree in environmental economics from the same university. His doctoral thesis focuses on flexibility in land and water use for coping with rainfall variability.

Over the past 10 years, Christian worked for various large climate and water related research projects, focusing mainly on East Africa and South Asia.

Next to the Grantham institute he remains connected to Alterra, one of the main research institutes of Wageningen UR.
