Christof den Biggelaar, Ph.D.

Research & Teaching Interests:

In addition to his knowledge and skills in agriculture, agroforestry and organic gardening, his areas of expertise include endogenous knowledge systems; farmer experimental practices and knowledge generation processes in agroforestry systems; participatory (RRA/PRA) and survey research methods; program evaluation; and qualitative and quantitative data analysis. 

Education

  • Ph.D. 1994 Michigan State
  • M.S. 1989 Michigan State
  • B.Sc. Hogere Agrarische School in 's Hertogengosch

Background

Christof is originally from the Netherlands, where he received an Agricultural Engineer's degree in Agronomy (equivalent to a B.Sc.) from the Hogere Agrarische School in 's Hertogenbosch. He then spent 6 years in Upper Volta (now Burkina Faso), the (then) People's Republic of the Congo and the Central African Republic as an agricultural teacher and extension agronomist. He obtained his M.S. degree in Agricultural and Extension Education at Michigan State with a certificate in African Studies ('89). Before embarking on his Ph.D. studies, Christof participated in a post-graduate training program on development-oriented research in agriculture (ICRA) in the Netherlands, which included a 3-month interdisciplinary field study on research-extension-farmer linkages in Southwest Province, Cameroon. For his Ph.D. (Forestry, Michigan State, '94), he studied farmer experimental practices with agroforestry systems in Rwanda. After completing his Ph.D., he spent two years in Kenya as a consultant for the World Agroforestry Center and FAO 's Forest, Trees and People Programme.

Christof joined the Sustainable Development faculty at Appalachian State University in August 2000. He teaches courses in agroecology and sustainable development. Since 2008, he coordinates the Agroecology & Sustainable Agriculture Concentration in the BS degree, and directs the activities at the Teaching and Research Farm in Valle Crucis.

Since 2005, Christof has been working as a technical advisor on agroforestry and sustainable agriculture for the Madagascar Fauna Group in Toamasina, Madagascar. He provides training for MFG staff at Parc Ivoloina and for farmers living around the park. He is also an adjunct faculty at the University of Toamasina's Gestion des Ressources Naturelles et Environnementales Program, teaching a course on Agroforestry and Soil Conservation and serving as technical advisor on students' thesis committees.
