Martine Vonk 
holds a Masters degree in Environmental Studies, Social Sciences & Development studies from Radboud University, Nijmegen. She is fascinated by issues that relate to sustainability, environment, agriculture, nature, communities and new approaches to church. She has previously worked as a consultant for sustainable agriculture and rural development and was a MP candidate for the Christian Union.

She recently started SPARK, an organization that focuses on projects in the field of sustainability—including group practice of sustainable food policies for rural municipalities. She also writes for publications for the Sustainability Research Institute of the Christian Union and is currently researching relationships between life and sustainability (impact of values on behavior choices). Her research covers the Amish, Hutterite, Franciscan and Benedictine communities.
