Sustainability, Vol. 12, Pages 1515: Sustainability and Collaboration: Crossdisciplinary and Cross-Sector Horizons (Sustainability)

The title of this article signals increasing collaboration across boundaries aimed at understanding and solving complex scientific and societal problems. The article is a reflective analysis of five intersecting keywords in discussions of sustainability and boundary crossing. This genre of discourse studies interprets language use, drawing in this case on a representative sample of authoritative definitions, case studies, and state-of-the-art accounts. The Introduction situates the discussion around the increasing number and size of teams as well as research across both academic disciplines and other sectors, followed by the five keywords that structure the overall argument. Section 2 examines the first of the five keywords, defining interdisciplinarity by marking its alignment with integration, confluence, interdependence, interaction, and balance. Section 3 considers the second keyword—transdisciplinarity—by tracing evolution of a problem-focused connotation, links to sustainability, inclusion of stakeholders, the imperative of critique, and transdisciplinary action research. Section 4 brings together insights on inter- and trans-disciplinarity in a composite “crossdisciplinary” alignment with collaboration, factoring in the nature of teamwork, public engagement, and translation. Section 5 then turns to learning, noting the difference between education and training then emphasizing transformative capacity, double- and triple-loop learning, reflexivity, and a transdisciplinary orientation. Section 6 takes up the final keyword—knowledge—by calling attention to inclusion, indigenous and local perspectives, nomothetic versus idiographic perspectives, the question of fit, and the nature of crossdisciplinary knowledge. The article concludes by identifying future research needs.
