01 — Biography

From landscape practice to Gaïa-graphy

Alexandra Arènes is a landscape architect, researcher, and co-founder of SOC (Société d'Objets Cartographiques) in Paris. Her work sits at the intersection of architecture, earth science, and the history of cartography, driven by a single question: how do we map a world that is no longer stable?

Her answer is Gaïa-graphy: a cartographic method that replaces the planetary view from above with a situated, volumetric view from within the Critical Zone, the thin reactive layer of the Earth where life and geology interact.

02 — The Seven Models

Terra Forma: Seven tools for living maps

Each model creates a new focal point through which territory is redrawn. They are not representations of places but instruments for seeing differently.

I
Soil
Inverted globe. Vertical section.
Turns the earth inside-out. Maps depth, strata, subsurface flows rather than surface. The ground is not a plane but a living volume. Inspired by Critical Zone science: from rock to sky.
II
Point of Life
Moving centres of experience.
Maps from the perspective of a living entity moving through territory. No fixed Cartesian grid. Orientation by points of life, not GPS coordinates. The Snark portolan chart as model.
III
Living Landscapes
Entangled territories.
Maps mutual dependencies between organisms, soil, water, and human infrastructure. The territory as Möbius strip: inside and outside folded into each other. No separation between nature and culture.
IV
Borders
Contested edges.
Replaces clear boundaries with gradient zones of conflict, negotiation, and cohabitation. Ecotones, not borders. Chemical Valley as case study: pollution has no cadastral respect.
V
Space-Time
Thickened temporalities.
Compresses multiple time scales into single representations. Geological deep time coexists with seasonal cycles and human events. The helix replaces the timeline.
VI
(Re)sources
Material & energy flows.
Traces resource extraction, transformation, and depletion cycles through territory. Geochemical cycles drawn à la Vernadsky. What enters, transforms, and leaves the Critical Zone.
VII
(Re)collection
Memory and traces. What remains after events: ruins, fossils, traces, memory embedded in landscape.
Maps what persists. The territory as palimpsest: layers of past events readable in present conditions. Ruins are not absence but accumulated presence. The cartographer as archaeologist of the living.
03 — Philosophical Foundations

The cosmopolitical turn in cartography

We sought to emphasize the limits of conventional representations of the globe, to go beyond them, to begin exploring new images. In this case, art does not seek to anticipate, but to fill a lack of representation.

— Frédérique Aït-Touati on Terra Forma, PCA-STREAM interview

Arènes's work rests on a precise philosophical operation: the shift from an anthropocentric view (territory as surface to be constructed) to a cosmopolitical view (territory as living volume inhabited by multiple agents). This is not a metaphor. It is a cartographic programme with mathematical equations.

🌍

Bruno Latour — Terrestrial Politics

Direct mentor and collaborator. Latour's argument that politics must "land" on the Earth rather than escape into the Global provided the philosophical urgency. His concept of the Terrestrial as a new political attractor shaped Arènes's cartographic ambition: maps that make you land, not fly away.

🔬

Jérôme Gaillardet — Earth System Science

Geochemist at IPGP (Institut de Physique du Globe de Paris). Co-author of the Gaïa-graphy paper. Provided the scientific rigour: residence times, geochemical cycles, OZCAR observatory data. Without his science, the maps would be speculative fiction. With it, they become speculative instruments.

Frédérique Aït-Touati — History of Science

CNRS Research Fellow, theatre director, co-creator of the "Inside" lecture-performance, and co-author of Terra Forma. Brings the history of cosmological representation: how each era invents its images of the world. The seventeenth-century cosmological upheaval as parallel to today's ecological crisis.

🧬

James Lovelock & Lynn Margulis — Gaïa Hypothesis

The foundational claim that the Earth produces its own conditions of habitability through the interaction of living and non-living systems. Arènes does not merely cite Gaïa; she gives it visual form through the spiral notation system in her Gaïa-graphic method.

Intellectual heritage
🏔

Albena Yaneva — Architectural Theory

PhD supervisor at Manchester. Expert in Actor-Network Theory applied to architecture. Provided the methodological bridge between Latour's social theory and Arènes's spatial practice. How to study design as it happens, not after the fact.

06 — Pedagogy & Workshops

How she teaches

Arènes's workshop format is consistent: participants receive field data from a specific territory and apply Terra Forma map models to produce speculative cartographies. Drawing is central. The process moves from observation to notation to conceptual model. She runs intensive workshops (typically 10–20 hours) across architecture schools internationally.

07 — Convergence Points with AT6012

Where your work meets hers

Points of structural alignment for your conversation with Arènes at AIARG.

Critical Zone

Both use it as the operating framework. She maps it cartographically. You map it pedagogically through 8 territorial cuts.

Marseille

Your field site. Her French context (SOC, OZCAR, CNRS). The city is a shared territory for both projects.

Living Maps

Her "always under construction" maps = your Living Knowledge Commons. Both reject finished, static artefacts.

Multi-scalar

Her scale ladder (planetary → organism). Your explore.curricula.dev does the same digitally.

Co-production

She insists on "accompanying the problem" with a collective. You insist on Participatory Action Research where students are co-researchers. Same principle, different medium: her maps are drawn collectively in workshops. Your commons is built collectively on GitHub.

The Gap You Fill

Terra Forma is a book. The ZKM exhibition is a physical space. Both are analogue. Your three platforms are the digital infrastructure she doesn't have. You offer what SOC has never built: a persistent, version-controlled, web-native commons where speculative maps can accumulate across time and cohorts.
