Smart Greening in Malmö: An Urban Forest in an Industrial Harbor

In Malmö’s Nyhamnen inner city district, a transformation is underway to reimagine a former ferry terminal into a living, breathing urban forest. What makes this initiative exceptional is not only its ecological ambition, but its smart, modular, and circular approach to greening a post-industrial space where traditional soil-based planting is impossible.

A post-industrial transformation

The Nyhamnen area, located north of Malmö Central Station, is transitioning from a logistical and industrial hub to a vibrant mixed-use urban district. However, areas such as the ferry terminal pose complex challenges. Decades of industrial activity have left polluted soil and hard surfaces that make conventional planting unfeasible.

To overcome these limitations, the City of Malmö is piloting a new kind of urban greenery: a modular forest of trees planted in large, freestanding steel containers. Oversized planting urns engineered to thrive atop asphalt allow trees and vegetation to be introduced without disturbing the underlying land.

Creating urban microclimates

Together, they form a terraced forest landscape with varied topography, offering microclimates and visual richness. Around 40 large and up to 200 smaller trees will be planted during 2025, including robust pine species previously untested in Malmö’s coastal conditions. The development acts as a living lab in the EU project ARCADIA, providing real-world data on how different tree species adapt to urban heat, wind, and weather exposure.

Designing with nature and identity in mind

The urban forest exemplifies smart city thinking through circular design. Instead of demolishing existing structures, designers have repurposed elements of the ferry terminal, turning old vehicle ramps into public seating terraces and fencing materials into urban furniture. This re-use of site-specific materials reduces construction waste and creates a distinctive identity rooted in the site’s industrial past.

Encouraging citizen participation

Through the ARCADIA project, the City of Malmö is also building an understanding of citizen needs and encouraging participation in greenery, recreation, and maintenance. For example, a Climathon was hosted in 2024 where students submitted designs for the greening of Nyhamnen in a competition, and meetings were hosted in a community park to explore ways for citizens to take part in the maintenance of urban greenery.

An adaptable solution

The development of the urban forest is the culmination of years of testing and development of blue-green urban landscape labs in collaboration with Sustainable Business Hub, IVL, SLU and VA Syd. The forest is currently planned as a ten-year installation, a flexible and reversible solution while the city continues to develop the surrounding areas. Its modular nature means that the plants can be relocated when needed.
