John Wilson is a free range facilitator and activist in East and Southern Africa, with strong links to West Africa. He has worked with many different organizations at different levels — from community-based organisations to regional and continental networks, to help facilitate a stronger food sovereignty movement in Africa. Increasingly, he is focused on helping to catalyze and support collaborative and strategic work on agroecology and food sovereignty. In recent years, he has also become a strong proponent and facilitator for a principles-based approach to development work. Working with very complex situations requires a way of decision-making and assessment based on guidance rather than goals; Principles Focused Evaluation has been a strong source of inspiration and experience for his practice.
