Simplifications of the real world affect the validity and reliability of gaming simulations. This challenges the application of gaming simulations as an instrument for experiential learning, reflective practices and data collection. This study investigates the effects of simplification on extracting tacit knowledge from human behavior by answering the research question: Can tacit knowledge in a simplified design of a gaming simulation be transferred without compromising the validity and reliability corresponding to the real-world complexity? By applying a participatory design a gaming simulation is tested as an instrument to extract tacit knowledge. To test and evaluate the validity of this application, simulation sessions have been performed with experts from the field. In simplifying reality, participants' participation emphasized that the most accurate representation of reality is a prerequisite for capturing tacit knowledge. This in turn contributes again to the validity of the simulation design. The results show that simplification of the real world didn't affect participants' perspective on the use of the gaming simulation as an experiential tool to enable learning processes or create awareness. And that a simplified simulation design, is still valid in addressing the real-world complexity, with minimization of the level of abstraction and maximization of the truthfulness.

Participation has been proposed to improve agricultural extension programmes in developing countries. This paper reports on experience with COCREATE, an approach to agricultural extension programmes that supports agricultural chain actors in self-directed learning in action research with smallholder farmers and local traders in Indonesia. This approach resulted in the changes in relation and task division between farmers and their local traders in the agricultural production and supply and chains, improved their market position and in new institutions.

Background. Revealing tacit knowledge often is seen as very valuable for organizations, although it is usually challenging to enunciate and share this type of knowledge. Methods. This study uses a participatory design and the application of a board gaming simulation as instruments to extract tacit knowledge. To illustrate this application, the gaming simulation is played with entrepreneurs from horticulture. Horticulture represents a complex social system where tacit knowledge plays a major role in the trade process. A participatory design process is used to explore whether the design and play of gaming simulations enable participants to explicate their tacit knowledge. Participants’ participation in designing the gaming simulation explicated that reconstructing reality was a prerequisite for their commitment. Results. The results from playing simulation sessions show that participants were able to: (1) narrow down the anecdotic behaviour to a few factors; (2) to structure these factors; (3) explore how these factors relate to trade barriers and (4) to explain which tactics are applied to foster trade. Conclusion. The educational value of this study is that it helped entrepreneurs in understanding complex real-life situations.

Sustainable agricultural development (SAD) requires empowerment and engagement of all actors in the agricultural production and supply chain to enable change. This paper proposes a novel framework for Participatory Sustainable Agricultural Development (PSAD) that distinguishes four main classes of factors that influence participation in SAD: environmental, economic, social and governance-related. The factors in each of these classes are analysed in relation to their effect over time, on the basis of 49 SAD programmes reported in the literature. Findings show that the social factors of engagement and empowerment, not often addressed in existing SAD programmes, are of significant influence to effect over time, as are the environmental factors of food safety, and the economic factors of production and capacity development. As such this paper shows that in in addition to the well-acknowledged need for knowledge and skills related to food safety, production and capacity development, SAD programmes also need to address the social factors of engagement and empowerment to enable sustainable change over time for SAD through participation.

Participation of local actors has shown to be of significant importance to the uptake of new approaches to agricultural initiatives in developing countries. This paper proposes a new approach to empower local chain actors to work together to understand their own and others’ challenges, to pursue common understanding of their situations and challenges, and to then co-create solutions. Reflection on each other’s position is crucial to this process, and is core to the participatory approach designed to this purpose. Agricultural chains are the focus of a case study in Indonesia involving both farmers and wholesalers in the chain. Results show that the approach has led to new forms of collaboration between farmers, and between farmers and wholesalers, increasing market potential.@en
