Transdisciplinarity and sustainability science: A response to Sakao and Brambila-Macias in the context of sustainable cities research.

Abstract In a recent Volume of this journal, authors Sakao and Brambila-Macias ask if we "share an understanding of transdisciplinarity in environmental sustainability research?". This response to their timely question argues that while transdisciplinarity is highly desirable, the accepted goal of incorporating multiple stakeholders in research projects (T2) may be problematic due to the heterogeneity that this introduces. This challenge is explored in two case studies taken from sustainable urbanism research, one focused on green gentrification, the other upon urban food production. The paper concludes with an endorsement of a sequential program of T1 and T2 research. Highlights • A Response to a paper in this journal, which asks if we "share an understanding of transdisciplinarity in environmental sustainability research?". • Explores two cases, one of green gentrification, the other urban food production, demonstrating the complicated content of sustainable cities research. • Response concludes that transdisciplinary research is necessary but must include a sequence of academic research (T1) and stakeholder participation (T2).
