Slow Down: The Slow Violence of Sand Extraction (1/2)

Listen to the first episode of “Slow Down”, a series investigating ways to slow down overheated sites, cities, and societies.

March 25, 2026

We are back with a new podcast series! Listen to the first episode of “Slow Down”, a series investigating ways to slow down overheated sites, cities, and societies. In this episode, we follow a deep dive into the Køge Bay and explore the violent praxis of marine sand extraction.

As part of her PhD, Emma Rishøj Holm descends to the seabed to experience firsthand the hidden consequences of marine sand extraction — a practice that is accelerating as land-based resources disappear, yet remains largely invisible. Together with Tideland Studio and marine biologist Stiig Markager, the conversation unfolds across ecology, infrastructure, and architecture, tracing a slow violence that reshapes the seabed — and exploring how architecture might play a role in bringing attention to it.

In the episode you will meet:

Emma Rishøj Holm: PhD Fellow at Arkitektskolen Aarhus. Focusing on sand extraction in the Køge Bay and sand-related proposals for material solutions in the construction industry.

Tideland Studio: A research-based design studio merging architecture with artistic expression, technological innovation and holistic sustainability. Through a profound understanding of both our natural and built environments, we design solutions, stories and experiences that resonate, transform and enrich.

Stiig Markager: Professor in marine ecology and biogeochemistry at the Department of Ecoscience at Aarhus University. A prominent voice in the Danish discussion about agriculture's impact on the marine environment.

The episode asks how designing with (and for) insects challenges aesthetic norms, maintenance culture, and anthropocentric planning.

If material producers took responsibility for the full lifecycle of their products, it could pave the way for a more sustainable building sector.
