Marja Spierenburg is Associate Professor/Senior Lecturer at the VU University Amsterdam in the Netherlands, in the Department of Culture, Organisation and Management. She is currently involved in several research projects focusing on the role of the private (for-profit and non-profit) sector in nature conservation as well as in land reforms in Southern Africa. Her research investigates the negotiations between the different parties but also within the different partner organisations concerning the meaning of the concepts of development and conservation. It also addresses the impacts of the growing importance of public-private partnerships in conservation on the land rights of local communities and the latter's possibilities to participate in the management of and benefit from conservation and land reform projects. Marja Spierenburg's earlier books and articles include 'Conservative philanthropists, royalty and business elites in nature conservation in southern Africa', co-authored with Harry Wels, published in 'Antipode' in 2010, 'Strangers, Spirits and Land Reforms, Conflicts about Land in Dande, northern Zimbabwe' (Brill 2004) and, together with Sandra Evers and Harry Wels 'Competing Jurisdictions. Settling Land Claims in Africa' (Brill 2005). Harry Wels is Associate Professor/Senior Lecturer at the VU University Amsterdam, at the Athena Institute, Faculty of Earth and Life Sciences. He has worked on issues of private wildlife conservation and community relations in Zimbabwe and South Africa. He has been working on structures of organisational cooperation within the Great Limpopo Transfrontier Conservation Area in southern Africa. Currently he is developing a transdisciplinary and transspecies research programme on traumatic stress related behaviour in humans and non-human animals in southern Africa. His earlier books and articles include: Private wildlife conservation in Zimbabwe. Joint ventures and reciprocity, (Brill 2003) and, together with Marja Spierenburg (2006) 'Securing space': mapping and fencing in transfrontier conservation in southern Africa in Space and Culture.
