Third Landscapes / Ruderal

Gilles Clément’s notion of the “third landscape” identifies marginal, unmanaged, and neglected sites as reservoirs of biodiversity. These residual terrains—fallow fields, infrastructural edges, abandoned lots—host ecological richness precisely because they escape planning and control. Clément elevates them as democratic landscapes, belonging to all because they belong to no one. They challenge design norms by valuing spontaneity, chance, and ecological autonomy. The third landscape reframes neglect as ecological and political potential.

Krater includes no landscape architects and follows no formal landscape architecture plan. Yet it is an intervention in landscape that stands as a provocative inquiry into the status of abandoned plots embedded within the urban fabric. The project poses fundamental questions: is a site truly ‘neglected’ if a thriving biotope has already taken hold? Could such a space, in its self-organized vitality, already constitute a form of an urban park? How to organize the social dimension? Krater unfolds as an expedition into landscape itself—an open-ended investigation in which fragmented architectural elements function as instruments of observation, experiment, and reflection. The site operates as a living laboratory, challenging conventional practices of open space production and the disciplinary boundaries of landscape architecture. It addresses relevant uncertainties the Anthropocene entails, engaging critically with issues of multi-species coexistence and the contested notion of environmental harmonization.

At a time when landscape architecture often seeks to simulate nature through aesthetic approximation or even mimicry, Krater seems oblivious to such representational impulses. Its proposition is radical in its restraint: rather than imposing form, it frames this ‘third landscape’ as a space of ecological processes, social encounter and experiment, revealing alternative logics of co-inhabitation, agency and design—logics that may become increasingly relevant as landscape architecture confronts its own ecological, ethical and epistemological limits.

BASE is a France-based studio known for its out-of-the-box thinking and unexpected design choices, often introducing challenges that can be overcome through play. Encountering an obstacle in a public space—one that invites engagement and risk-taking—creates a tension that can lead to moments of joyful liberation. A key aspect of BASE’s approach is putting trust in […]

Del Tredici’s argument is that these spontaneous plants are “de facto native urban flora” considering the novel conditions produced by humans. It is an argument against perceiving spontaneous vegetation including invasive, non-native plants and plants considered as weeds, to be less worthy. Labelling a plant “invasive” or “weed”, says Del Tredici, gives people the licence to blame it for ruining the environment and to get rid of it.

A post-industrial park is typically a sexy landmark, easy to make a story of, photogenic, and a palimpsest in itself. It presents a victory of public use over the private and industrial by opening previously closed-off spaces. A post-industrial park offers some crucial topics of remediation, adaptive reuse, and social integration, among others. For a […]

When we speak of Nature in cities, the question we want to stress is, is nature in cities natural or in fact an artefact? When we speak of natural processes, they of course take place but apart from spontaneous nature, left to random succession, emerging in spaces that Gilles Clément calls the third landscapes, there […]

Urban biodiversity? Yes, please! Nevertheless … … Due to the transitional phase of our understanding of nature in the light of the Anthropocene, there are still some important notions, contradictions and misunderstandings that need to be addressed. To do so, we will operate with terms like nature, ecology, biodiversity, landscape, and aesthetics, and we’ll focus […]

We are thrilled to share with you the interview with LILA 2022 Honour Award winner Gilles Clément. The interview was conducted in Paris in November 2022 by Zaš Brezar and Joost Emmerik. The editors wrote in the award statement: Gilles Clément (1943) is a French landscape architect or better ‘paysagiste’, having a more garden design-related […]
