Transitions towards sustainability are urgently needed to address the interconnected challenges of economic development, ecological integrity, and social justice, from local to global scales. Around the world, collaborative science-society initiatives are forming to conduct experiments in support of sustainability transitions. Such experiments, if carefully designed, provide significant learning opportunities for making progress on transition efforts. Yet, there is no broadly applicable evaluative scheme available to capture this critical information across a large number of cases, and to guide the design of transition experiments. To address this gap, the article develops such a scheme, in a tentative form, drawing on evaluative research and sustainability transitions scholarship, alongside insights from empirical cases. We critically discuss the scheme's key features of being generic, comprehensive, operational, and formative. Furthermore, we invite scholars and practitioners to apply, reflect and further develop the proposed tentative scheme -making evaluation and experiments objects of learning.

This article provides a rationale for inner transformation as a key and hitherto underresearched dimension of sustainability transformations. Inner transformation relates to various aspects of human existence and interactions such as consciousness, mindsets, values, worldviews, beliefs, spirituality and human–nature connectedness. The article draws on Meadows’ leverage points approach, as places to intervene in a system, to reveal the relevance of inner transformation for system change towards sustainability. Based on insights from a series of dialogue and reflection workshops and a literature review, this article provides three important contributions to sustainability transformations research: first, it increases our conceptual understanding of inner transformation and its relevance for sustainability; second, it outlines concrete elements of the inner transformation-sustainability nexus in relation to leverage points; and third, it presents practical examples illustrating how to work with leverage points for supporting inner transformation. In sum, the paper develops a systematized and structured approach to understanding inner transformation, including the identification of deep, i.e., highly influential, leverage points. In addition, it critically discusses the often contentious and divergent perspectives on inner transformation and shows related practical challenges. Finally, current developments in inner transformation research as well as further research needs are identified.

ZusammenfassungDer Beitrag beleuchtet die Funktion von Reallaboren als Rahmen für transformative und transdisziplinäre Forschung. Dazu wird zuerst ein Verständnis von Reallaboren vorgelegt, das auf der Reflexion praktischer Erfahrungen von Reallaboren in Baden-Württemberg beruht. Ausgangspunkt hierfür ist ein Verständnis von Reallaboren als Infrastruktur für Realexperimente und andere transdisziplinäre Projekte. Aufbauend auf diesem Verständnis werden die Ziele der Reallaborarbeit in drei Dimensionen, den Forschungs-, Praxis- und Bildungszielen beschrieben. Um einen solchen Rahmen herzustellen und zu pflegen, werden fünf Designprinzipien vorgeschlagen: Problem- und Themenangemessenheit herstellen, räumliche Angemessenheit gestalten, zeitliche Angemessenheit herstellen, angemessene Akteursrollen etablieren sowie experimentell-reflexive Arbeitsweise fördern. Den Abschluss bildet ein Schema aus Zieldimensionen und Designprinzipien, das bei der Ausgestaltung von Reallaboren als Hilfestellung dienen soll, das aber auch als Reflexionsschema verwendet werden kann.

Real-world laboratories (RwLs) are a form of transdisciplinary research that facilitates learning processes as part of its transformative objectives. Nevertheless, little conceptual effort has been put into the understanding, planning, and evaluation of the learning dimension of RwL work. This paper applies a systematic approach from the discourse on education for sustainable development (ESD) to differentiate three perspectives on the various learning processes occurring in RwLs and exemplifies them with experiences from the RwL Urban Transition Lab 131 in Karlsruhe.

Real-world laboratories (RwLs) from an inside perspective: comparing interior design, sustainable development, transformation and learning in three RwLs, we present core issues for the future design of RwLs.Real-world laboratories (RwLs) as a new format within transdisciplinary science aim at promoting learning for and transformation towards sustainability. However, what are essential aspects to take into account while initiating and stabilizing such processes within RwLs? Comparing lessons learned of three German RwLs (BaWü Labs), we show that for establishing RwLs as melting pots for transdisciplinary research and societal transformation, four properties are crucial: an interior design that enables transdisciplinary research and intervention (in particular real-world experiments) based on a stable infrastructure; sustainability as guiding and operationalized principle for differentiating the format “RwL” from other labs; overarching research programs for assessing transformative effects of RwLs and didactic concepts suitable for RwL circumstances. Since RwLs mainly address a long-term cultural change, a long-term funding and research structure are essential as well.
