Now is the time for nature recovery.
There is widespread recognition that the ongoing and rapid decline of the natural world cannot continue, both for the sake of our fellow species and hist ecosystems, and for humanity itself. The agenda of large-scale action to restore the natural world has gained prominence in recent years, with policy initiatives ranging from local and national through to the UN Decade of Ecological Restoration and Global Biodiversity Framework of the UN Convention on Biological Diversity. Governments, conservation groups, and academic institutions recognise that striving to protect what remains of the natural world is no longer enough—we must also repair some of the damage that has been done.
There is a plethora of terms to describe this new agenda, including restoration, nature-positive actions and rewilding. Whilst all these terms have their merits, we argue that nature recovery is a particularly salient and needed term that captures this ambitious, multiscale and interdisciplinary vision. However, to date, the term remains poorly defined, a mix of very technocratic concepts linked to specific policies and a broad umbrella term covering a broad range of conservation and restoration activities. There is an opportunity, indeed a need, to develop a definition that highlights concepts and approaches that nature recovery can embrace without providing a strong constraint on its use. At the Leverhulme Centre for Nature Recovery at Oxford University, we have (not surprisingly) come up with what we would like to propose as a good definition, which emerged after consultation from a wide range of disciplines. This definition is gaining some traction, and in this article, I will unpack it and explain why I think it is useful. But first, let’s have a brief history of the term nature recovery.
The term nature recovery originates in the United Kingdom, where it is embedded in national environmental policy. The UK’s 25-Year Environment Plan, published in 2018, introduced the concept of a Nature Recovery Network (NRN)—a large-scale initiative designed to create and link wildlife-rich habitats across the country. The NRN aims to rebuild biodiversity by reconnecting fragmented landscapes and ensuring that natural areas are not just protected but actively restored. Following this, The Environment Act of 2021 made Local Nature Recovery Strategies (LNRS) a statutory requirement. These strategies compel local authorities to map out areas where nature restoration should be prioritised, integrating nature recovery into spatial planning. Other initiatives, such as the UK Wildlife Trusts’ Nature Recovery Network Handbook, provide practical guidance on how communities, landowners, and policymakers can contribute to ecological restoration. As another example, the UK’s Environment Agency has launched the Nature Recovery from Source to Sea program, focusing on restoring rivers, wetlands, and coastal ecosystems. Nature recovery is now a term widely employed in UK environmental policy.
The goal envisioned in these polices is not only about preserving existing green spaces but about expanding and connecting them, recognising that nature needs to thrive even in human-dominated landscapes. In the meantime, the word has spilt out from its specific policy origins to become a convenient umbrella term for a broad range of activities associated with protecting and restoring biodiversity.
While “nature recovery” has become prevalent in the UK, it has synergies with a wide range of international initiatives aimed at large-scale recovery of biodiversity and ecosystems. The United Nations has declared 2021–2030 as the Decade of Ecosystem Restoration, encouraging governments to rehabilitate degraded ecosystems. The Society for Ecological Restoration (SER) defines ecological restoration as the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed. In Europe and North America and increasingly more widely, rewilding is a resonant if sometimes controversial term, emphasising the restoration of self-sustaining ecological processes through reintroducing keystone species or their functional equivalents and reducing human intervention. The context is very different in the vast semi-natural landscapes of North America, where the emphasis has been on ecological connectivity, large herbivores and top predators such as the wolves of Yellowstone, and in the densely populated landscapes of Europe, where the emphasis has been on iconic species such as beaver, and on the use of semi-domestic animals such as feral cattle to replace functions once provided by megafauna and even extends to expansion regeneration of vegetation, and wilder gardens and cities.
Another widely employed term is nature-based solutions, which organisations such as the International Union for Conservation of Nature (IUCN) and the European Commission use to describe projects that use natural processes to address environmental and societal challenges—such as restoring wetlands to mitigate floods or planting trees to cool urban areas or restoring forests for carbon sequestration. Though these terms share similarities with nature recovery, they often focus on specific methods or scales of intervention, or specific goals. Some, like rewilding, have become occasionally embedded in culture wars and viewed with suspicion.
The Leverhulme Centre for Nature Recovery is an interdisciplinary centre created in 2022, focused on understanding what is needed to realise the vision of restoring the natural world. It recognises that this requires broad thinking that stretches beyond ecology to the social and political sciences, economics, humanities and the medical sciences. Alongside implementing a range of research activities across this agenda, we embarked early on an interdisciplinary discussion of what we mean by nature recovery. Here is the definition we came up with:
“Nature recovery is the activity of helping life on Earth to thrive by repairing human relationships with the rest of the natural world.”
This definition fixes no baseline or endpoint for nature recovery: by “helping life on Earth to thrive”, it prioritises the direction of travel over the endpoint. We think that this definition is more flexible and inclusive than terms like rewilding or ecological restoration. Nature can recover in schools, in workplaces, in cities, in farmlands and in wilder areas. Hence, it serves as an umbrella term for a broad range of activities that increase biodiversity and enhance ecosystem functions. This is important in recognising that it is insufficient to focus activities in well-protected areas alone; natural processes need to connect and flow across human-modified landscapes and seascapes, especially in an era of climate change. Urban areas can also be hotspots of nature recovery activity because they can host surprising levels of biodiversity compared to intensively farmed countryside, and they offer the primary point of nature connection for an increasingly urbanised human species.
A second feature of this definition is its focus on repairing human relationships with the rest of the natural world. This recognises human relationships as a key requirement for nature recovery, and that humans emerge from, and are embedded within, the natural world, thus rejecting human-nature dualism. Environmental degradation is not simply an issue of lost forests or declining wildlife—it is a systemic issue rooted in economic models, governance structures, and cultural attitudes. This definition emphasises that nature recovery is fundamentally about transforming how humanity as whole interacts with the rest of the natural world, though there is much to respect in and learn from the world’s many cultural and spiritual traditions. The theme of human relationships stretches from intimate local connections with nature through to nature connection and the benefits it can provide in our education and public health systems, through to a deeper examination of how and why our modern economic and cultural systems are leading to a breakdown of the natural world, and how we can work with these systems to develop a realistic vision of human flourishing with the rest of nature. Such a broad definition recognises the need for deeper and transformative change in our culture, values and economies while giving space and encouragement to local and practical actions in urban, agricultural and wilder landscapes. This forward-looking perspective encourages us to reimagine human-nature relationships as opportunities for collaboration and coexistence with the rest of nature rather than sources of conflict and harm.
By placing human responsibility at the centre of nature recovery, we argue that this definition embraces a more holistic approach that addresses systematic issues whilst also enveloping local action. I have argued above why a broader and more inclusive term is needed to address these ambitious goals and systematic challenges and why our definition of nature recovery meets this need. Nature recovery, or a term similar to it in breadth and inclusivity, is an essential concept for the 21st century, where we seek to reverse the decline of the natural world and create a world in which humans and the rest of nature can thrive and flourish together.
Now is the time for nature recovery.
