Culture, Nature, and the Valuation of Ecosystem Services in Northern Namibia

Defining culture as shared knowledge, values, and practices, we introduce an anthropological concept of culture to the ecosystem-service debate. In doing so, we shift the focus from an analysis of culture as a residual category including recreational and aesthetic experiences to an analysis of processes that underlie the valuation of nature in general. The empirical analysis draws on ethnographic fieldwork conducted along the Okavango River in northern Namibia to demonstrate which landscape units local populations value for which service(s). Results show that subjects perceive many places as providing multiple services and that most of their valuations of ecosystem services are culturally shared. We attribute this finding to common experiences and modes of activities within the cultural groups, and to the public nature of the valuation process.

Transdisciplinarity as a real-world challenge: a case study on a North–South collaboration

Transdisciplinarity (TD) has become a buzzword, promoted as a suitable approach to address today’s urgent challenges in human-environment interactions. Looking at its practical implementation, however, challenges still remain to be met. Despite the concept’s popularity, it seems difficult to reconcile the idea of knowledge co-production with research realities. Taking a TD research project dealing with sustainable land management in Southern Africa (Angola, Botswana, and Namibia) as a case study, we aim to provide empirically based insights into the real-world application of this collaborative research approach to improve the general understanding of TD research in the making. Based on semi-structured interviews with project partners and stakeholders, we reveal the underlying interests, mismatching institutions and structures of power shaping the TD research process in this North–South collaboration. We identified TD as falling victim to a kind of “tragedy of the commons”, paralysed between existing power structures and conflicting interests, and being considered as extra work instead of an integral task with an inherent value in itself. By demonstrating some of the underlying causes of the challenging practice of TD, we reveal starting points for changes and provide recommendations that aim to set the base for a more reflexive and fruitful TD knowledge co-production.

Sustainability science as if the world mattered: sketching an art contribution by comparison

Here, I investigate some of the potential contributions of art to the emerging field of sustainability science. First, the involvement of sustainability thinking in art is massively increasing. Second, there is a line of interactions between art and science that do not necessarily take sustainability as their content, at least in an ecological sense. Third, there are a considerable number of examples of sustainability science projects that are intended to link knowledge to social action without involving art. I exemplarily compare these different combinations to gain a concise overview of and differentiate between current activities and to identify some shortcomings and potentials of various contributions. The utilitarian and rather pragmatic question I ask is: What does art have to offer to sustainability science that the latter currently lacks? This question is asked from my own anthropological viewpoint, that of cultural and social science, partaking in sustainability science. I use empirical insights from sustainability projects in Africa that I took part in, which specifically dealt with sustainable land management. I blend these findings with results from a broad literature review and a comparison of multiple existing art projects. I show that a sustainability science that aims to matter to people and that takes its core tenet of linking the produced knowledge to sustainable social action seriously while facing an existing crisis of agency and knowledge would strongly benefit from opening to an experimental and experiential approach to knowledge production that explicitly includes processual, affective, and sensory types of knowledge, imaginative agency, and conceptual forms of interaction.

Self-governance and punishment: An experimental study among Namibian forest users

We use a framed field experiment to assess resource harvesting behavior and its interaction with prosocial and antisocial punishment in the Kavango woodland savannah of Namibia. We implement two treatments, one with external, centralized punishment and one with internal, decentralized punishment. Our findings suggest that institution type matters, as internal punishment is a more effective regime to discipline high harvesters compared with external punishment. We find that antisocial punishment (i.e., the sanctioning of people who cooperate by free riders) happens frequently, partly as revenge and especially in ethnically heterogeneous groups, but ultimately does not prevent cooperative self-governance.
