Overview of the special issue: embracing the messiness of transdisciplinarity

This Special Issue utilizes a transdisciplinary lens to analyse how environment-related problems are being framed and communicated in different settings. A drive for net zero greenhouse gas emissions, preserving biodiversity, or reducing pollution can challenge deeply entrenched values and interests in the status quo. These values and interests can affect how different people understand or frame questions about the environment. They underlie societal debates and negotiations, and they affect how communication about environmental issues occurs and what bodies of knowledge are drawn on and given authority. These dynamics indicate that addressing such complex problems entails the development of new ways of sharing knowledge, coordinating practices, thinking, and experimenting to progress toward a joint purpose or resolution when an array of stakeholders is engaged. Our overview identifies some of these approaches as they have surfaced across this collection of articles.
