Risk of cultural heritage being forgotten
The green transition
Throughout the Nordic region, we’re preparing for floods, forest fires, landslides, and rising sea levels in the wake of climate change. However, sometimes climate adaptation itself poses a threat to the cultural heritage of certain locations. This is shown in a new report, which also lists examples of good solutions in use throughout the Nordic region.
Bryggen, the colorful row of old wooden buildings in Bergen, Norway, is a UNESCO World Heritage Site. In preparing for increasing rainfall, the city didn’t bury deep drainage pipes but set up rain beds instead.
A rain bed, or “rain garden,” can soak up a lot of rainwater while benefitting biodiversity in the city and leaving archaeological cultural monuments in the subsoil untouched.
In the new Nordic report “Climate adaptation measures and cultural heritage,” the rain beds in Bergen are hailed as a good example of climate adaptation that also benefits the city’s cultural heritage.
Cultural heritage is destroyed by the sheer rate of change
This report is the result of a Nordic project that looked at how cultural heritage in the Nordic countries is affected by climate adaptation.
The aim is to improve understanding of the vulnerability of cultural heritage in the green transition.
During the ongoing green transition, we’re building wind farms, erecting solar panels and charging stations, building flood barriers, draining agricultural land, insulating houses, and burying gas pipelines.
Consequently, there’s a risk of changing old cultural landscapes, natural and cultural heritage, and building environments characteristic of our time.
“We’ve built sustainably before”
According to Annika Haugen, project manager at the Norwegian Institute for Cultural Heritage Research, it’s not uncommon for climate adaptation to take place without any concern for older building environments, archaeological cultural monuments, or cultural landscapes.
“However, it’s important that we bring our cultural history with us into the future, both by taking cultural heritage into account, but also using it as a source of knowledge. We’ve built sustainably in the past, and over the centuries we’ve learned to adapt the design and placement of buildings to heavy rainfall and other extreme weather conditions. We mustn’t forget history and try to solve the green transition using new methods and technology alone,” says Haugen.
She emphasizes the concept of “culture-based solutions,” that is to say historical climate adaptation, as part of the answer to how we can deal with climate change.
“In a sustainable future, we wouldn’t build so much from scratch. We’d convert what already exists and recycle building materials. Knowledge of old methods, materials and construction planning then becomes tremendously important,” she says.
Examples of carefully sited wind farms
Most municipalities in the Nordic region are working to prepare for larger quantities of precipitation. If we choose to deal with this by burying larger wastewater pipes, we risk both destroying archaeological material and disturbing the groundwater level, which can lead to subsidence and the destruction of older wooden structures.
The report gives several good examples of how towns and cities have prepared for torrential rain, floods, and landslides using methods that benefit both biodiversity and cultural heritage.
It also gives examples of how to site solar and wind farms to avoid changes to cultural landscapes and cultural heritage.
Include cultural heritage experts
The report recommends that all sectors of society be involved early in the processes, both when it comes to establishing renewable energy sources and direct climate adaptation.
Archaeologists, architects, building antiquarians, biologists, and other experts on rural natural and cultural heritage should also be involved in designing contingency plans and environmental impact assessments.
It also proposes a Nordic pool of expertise in the form of an expert network and a database with good examples of projects where cultural heritage is included in climate adaptation.
