The role of learning in transdisciplinary research: moving from a normative concept to an analytical tool through a practice-based approach

Transdisciplinary (TD) research is an example of a participatory research approach that has been developed to address the complexity of societal problems through the exchange of knowledge and expertise across diverse groups of societal actors. The concept of knowledge exchange is central to the ability of TD research to produce usable knowledge. There is, however, limited theoretical attention to the processes that enable knowledge exchange, namely learning. In this article, we analyze the “transferability” of knowledge generated in TD research settings from a practice-based approach. In this approach, learning and knowing are seen as situated in social practices, in meaning making processes where the involved participants make sense of what they do and why they do it. We describe and analyze three TD projects, and discuss the role of practitioners’ perspectives in the interpretation of the tasks and realization of TD, and in the consequences this has for the organization of the research process and the usability of its results. The analysis shows that while the project teams were given the same task and framework, they did not understand or enact TD in a similar fashion. The three projects created different goals and organizations. They also resulted in different challenges, which could be identified and analyzed by the use of a practice-based approach to learning. In the conclusions, we identify aspects for both practice and research that are important for creating sufficient conditions for learning in TD research processes so that they can better promote contributions to societal change.     

How can we ever create participation when we are the ones who decide? On natural resource management practice and its readiness for change

This article addresses the gap between demands for participatory approaches in natural resource management (NRM) policies and lack of such approaches in the work of environmental authorities. The analysis draws on practice theory, using the case of NRM practice created by Swedish County Administrative Board (CAB) officials. The data originate from officials’ reflections during courses designed to strengthen their participatory and collaborative competences. Based on practice theory, officials are seen as participants of a routinised practice in which their interpretations of their work and roles are socially constructed. The analysis shows that the objective of this practice is to protect nature and mitigate resistance from stakeholders through information. These interpretations have acquired a reified nature, making them taken for granted. This stabilises the practice, maintaining the gap between demands in national policies and their implementation. To enable change in the CAB practice, the objective constructed by officials needs to be reinterpreted to produce a rule of law that can be justified and which concurrently permits stakeholder participation. To achieve changes in NRM officials’ practice, these need to be seen in their institutional context and comprise the whole system, from international/EU auditing levels to Swedish CABs and the officials’ everyday activities.     

The measurement of roadway PM10 emission rates using atmospheric tracer ratio techniques

In this work, stationary and mobile point source tracer release techniques have been used to determine PM₁₀ emission rates from four-lane commercial/residential paved roads under sanded and unsanded conditions, and from unpaved roads relative to site-specific vehicular and ambient parameters. Measured street (4 + lanes; ? 10,000 vehicles per day) emission factors for unsanded and sanded roads were 40 and 20% lower, respectively, than the EPA approved reference value. The sanded road emission factor was approximately 40% higher than that for the unsanded road. These results indicate a consistent relationship between PM₁₀ and relative humidity under unsanded conditions. There is some evidence to suggest that street sweeping has a measurable effect on PM,, emission reduction during periods of low relative humidity (i.e. ? 30%). Within the constraints imposed by the variable experimental conditions, the emission factors determined for unpaved roads agreed reasonably well with the unpaved road empirical formula. Limited correlations were observed with ambient meteorological parameters. The capability of the “upwind-dowiawind” concentration modeling method to predict accurate emission was tested using a Gaussian dispersion model (SIMFLUX). Predictions agreed well with the experimentally determined emission factors.
