Designing a transition towards circular economy of water: Examining practitioners' understandings in the Netherlands.

Abstract

This paper examines how new policy concepts are taken up in practice, focusing on the Circular Economy of Water (CEW) in the Netherlands. Drawing on 20 semi-structured interviews with practitioners from different governance levels, regions, and sectors, we analyze how CEW is interpreted, reshaped, and mainstreamed into existing water-governance structures. We identify six lock-ins that constrain CEW's implementation and three mechanisms through which it is mainstreamed. Our findings show that lock-ins and mainstreaming mechanisms are closely interconnected: While CEW adapts to existing systems, it can also reinforce them, at times leading to rebound effects or supporting business-as-usual practices. This study contributes to a deeper understanding of the dilemmas related to CEW governance, offering insights to enhance sustainable water management practices and transformative changes. We argue that design-oriented approaches can inform how CEW is imagined and implemented, helping to reconsider whether it addresses the causes of unsustainable practices or offers temporary fixes.
