The most significant threat to biodiversity is land development, not climate change as some might believe
Bernt-Erik Sæther, director of the Centre for Biodiversity Dynamics
The UN’s biodiversity panel, IPBES, ranks “land-use change” as the greatest threat to biodiversity (NTNU Event, 2022, 7:50). In 2022, WWF published a comprehensive report on the frequency and scale of biodiversity and climate changes. The report discusses the “2022 global Living Planet Index,” which shows an average decline of 69% in monitored wildlife populations between 1970 and 2018 (Almond et al., 2022, p. 12). It also highlights how the biodiversity and climate crises are interconnected, like two sides of the same coin—solving one requires addressing the other (Almond et al., 2022, p. 4).
An article titled Norway in Red, White, and Gray from the Norwegian Broadcasting Cooperation (NRK) used artificial intelligence to map 44,000 instances of environmental encroachment in Norway over the past five years (Mon et al., 2023).

However, according to biology researcher Ivar Herfindal from Norwegian University of Science and Technology (NTNU)´s Department of Biology, this mapping only provides a skeletal overview of environmental impacts (NTNU Event, 2024, 22:40). He emphasises that satellite images do not reveal which species are affected by development, requiring more detailed investigations. This means that we have lost a lot more than this map can show us.
The NRK series The Inspector featuring Bård Tufte Johansen, also highlights nature loss, showing how various infrastructure developments—such as roads, wind power, and industry—gradually consume Norwegian nature piece by piece (NRK, 2024). This leads to habitat fragmentation and species extinction.
In his lecture “Why Can’t We Sacrifice Nature for the Green Transition?” professor Dag Hessen argues that nature is often compromised in favour of shorter travel times (Det Norske Vitenskapsakademi, 2023, 12:04). In an interview with Naturviterne, Hessen also emphasises that public engagement and awareness are crucial in influencing political decision-makers and driving change (Hundere, 2024).
But is is not only animals and plants that suffer from the nature shrinking. Humans also have a need for higher biodiversity and bigger green spaces around them – especially those living in urban areas. Urban living provides access to education, healthcare, and diverse cultures, but it often comes at the cost of health and well-being. Studies have linked urban environments—characterised by limited greenspace and high pollution—to increased rates of depression, anxiety, and attention disorders (McDonnell, et. al., 2024). Chronic conditions like cardiovascular disease, high blood pressure, and obesity are also more prevalent in cities. To counter these effects, researchers highlight the benefits of exposure to nature, which can improve cognitive function, mood, and creativity while promoting physical health by encouraging exercise, reducing stress, and lowering blood pressure. Additionally, natural spaces foster social interactions and help combat loneliness.
Despite national environmental goals aimed at preserving important outdoor recreation areas, only 45% of the population in cities and towns have adequate access to nearby nature and walking trails. In the largest cities, this percentage is even lower (WWF, 2021).
Area neutrality involves restoring areas of nature to compensate for the loss of natural land, due to development elsewhere.
Bernt-Erik Sæther, the director of the Centre for Biodiversity Dynamics CBD, discusses in a talk at Arendalsuka – the largest political gathering in Norway – how here is currently a lack of an overarching strategy to identify and regulate which parts of Norway’s natural areas should be preserved (NTNU Event, 2022, 13:33). A strong national framework for regulating land development is needed. Since much of the decision-making power lies with municipalities or landowners, each municipality is left to make decisions independently, often without considering the broader picture.
However, the government is now working on a government report on nature, which is expected to outline how concepts such as area neutrality, nature positivity, and natural accounting will be implemented in Norway (regjeringen.no, 2023). A recent survey also shows that 80 Norwegian municipalities have plans to become “area neutral” (Nyhus, 2023). This is on the foundations of the COP15 in 2022, where governments from around the world came together to agree on a new set of goals to guide global action through 2030 to halt and reverse nature loss (UN, 2022).
Conclusion
Only if Norway and other states establish clear goals to prevent nature loss, define precise terms, and create reliable indicators to measure biodiversity loss, can they effectively strengthen the decline in biodiversity. However, policy alone is not enough – public engagement and awareness are crucial in influencing political decision-makers and driving change.
