A host of positive “tipping points” can spark rapid nature recovery, a leading expert says.
Action to protect and restore nature must accelerate radically to meet global goals for 2030 and beyond.
Writing in the journal Nature Sustainability , Professor Tim Lenton says positive tipping points are key to achieving this.
He highlights potential tipping points – moments when a small change triggers a rapid, often irreversible transformation – in nature, human societies and areas where the two combine.
“The destruction and degradation of the natural world pose an existential threat,” said Professor Lenton, of the Global Systems Institute at the University of Exeter.
“We are already crossing or approaching several dangerous ecological tipping points , including the dieback of warm-water coral reefs and the Amazon rainforest.
“But just as human activity can drive negative tipping, we can bring about positive tipping points to spark large-scale nature recovery.”
While addressing climate change is vital for protecting nature, specific social and ecological tipping points can regenerate ecosystems, spread nature-positive activities, and reduce drivers of nature loss.
Many governments are signed up to international goals to regenerate nature – such as protecting 30% by 2030 – but progress is going far too slowly. Crucially, triggering positive tipping points can help achieve the necessary acceleration in progress.
Positive tipping points offer opportunities for businesses who are trying to work out how they can have a positive impact on nature, and for finance companies who are trying to identify investable opportunities in nature regeneration.
Professor Lenton identifies four key types of positive tipping point for nature:
Professor Lenton said a key research opportunity is to test which current systems may be approaching a positive tipping point – potentially inspiring action to trigger it.
He identifies three levers that could enable multiple positive tipping points: facilitating online collective learning among groups taking nature-positive action, properly valuing nature in economics, and tipping worldviews to “ecocentrism”.
On the latter, Professor Lenton said: “Changing the ethical and legal status of nature is a powerful practical step to underpin nature-positive action. Such a tipping point in paradigm could be the deepest leverage point for nature-positive system change.”
