Abstract

Novel assemblages of biotic, abiotic, and social components resulting from human-induced actions (e.g., climate change, land-use change, species movement) have been labeled as “Novel Ecosystems”, or “Novel Urban Ecosystems” when emerging in urban contexts. This concept has been shifting perspectives among some scientists and making them question traditional values about human-nature interactions in a rapidly changing era dominated by anthropogenic actions (Anthropocene). Controversial dimensions surrounding the Novel Ecosystems and Novel Urban Ecosystems terms may be preventing the evolution and further research of these concepts. The environmental problems that our society will soon face support a search for innovative solutions and transdisciplinary efforts. For that reason, this discussion should not cease, rather should expand to other fields of knowledge that can contribute with pertinent insights and collaborations. This way, this short communication aims to reflect on the opportunities from Landscape Architecture to the discussion, research, and application of the novel ecosystems concepts in the real world, particularly in the urban landscape, and also reflect on the opportunities of this debate to the Landscape Architecture field. Ultimately, Landscape Architecture can contribute with innovative and creative perspectives, acceding valuable and advanced tools, facilitating dialogues between fields of knowledge, and bridging gaps between science, people, and nature.

Highlights

  • Over the last decades a concept has emerged to describe unprecedented combinations of biotic, abiotic, and social components resulting from human-induced actions, but with a tendency to manifest novel qualities without, or in spite of, extensive human intervention [1,2,3]

  • The concept is being referred to as “Novel Urban Ecosystems” (NUE) and has gained a renewed relevance since ecological novelty is widespread in urban landscapes, where the impacts of human actions are more profound and prevalent [7,8,9]

  • We argue that Landscape Architecture can contribute to the understanding and clarification of this concept mainly in urban contexts

Summary

Introduction

Over the last decades a concept has emerged to describe unprecedented combinations (and interactions) of biotic, abiotic, and social components resulting from human-induced actions (e.g., climate change, land-use change, or species movements), but with a tendency to manifest novel qualities without, or in spite of, extensive human intervention [1,2,3]. The NUE concept can be relevant for the evolution of the discipline, especially by promoting a professional practice more grounded and focused on solving environmental problems emerging worldwide in the “new” age of the Anthropocene, and able to keep up with current hot topics and innovation pathways. To address these objectives, it is important, to explain and synthesize the most consistent and dominant controversial aspects of this concept by presenting the arguments both researchers’ factions have used in the literature, namely resorting to published papers that have initiated an ongoing action-reaction discussion. - we present arguments that support the opportunities from and to Landscape Architecture, briefly resorting to examples that demonstrate how the profession has already contributed to this subject
