Personal profile

Personal information

Roelf  L. Voortman is senior research fellow land resources and agriculture at the Amsterdam Centre for World Food Studies of the Vrije Universiteit, Amsterdam. He obtained his PhD in 2010 at the Vrije Universiteit Amsterdam.


As land resource ecologist, his main research interest is agro-ecological characterization and assessment for agricultural development planning with emphasis on the relationship between soil parent material-climate-soil-vegetation and how this is expressed in soil chemical properties, including micronutrients, with the objective to develop site-specific fine-tuned fertilizer technologies. Other research experience includes country-wide agro-ecological zoning (Mozambique, Nigeria), climate change (Nigeria country-wide), soil survey and land evaluation, mineral scarcity, biofuels, human nutrition as related to soil chemistry, and bio-indication (vegetation as indicator of soil chemistry).
