Imagine watching a forest fall, knowing that every tree has been priced, modelled and ranked in spreadsheets – and still seeing the chainsaws win. That uncomfortable gap between valuing nature on paper and saving it on the ground est au cœur du débat actuel sur la façon de réussir un véritable planet rescue.
When valuing nature fails to stop destruction
At the 2012 Earth Summit in Rio, celebrities and scientists stood together to argue that putting a dollar value on ecosystems could flip the script of environmental conservation. The logic felt simple: if coral reefs, mangroves and rainforests became visible as “assets”, governments and investors would finally protect them.
That idea, grouped under the banner of ecosystem services and “natural capital”, spread fast. Academic papers multiplied, consultants built models, and major organisations from The Lancet to WWF explored how pricing ecosystem benefits might change decisions. Yet wildlife populations kept crashing, protected habitats shrank and species slid quietly towards extinction. Numbers moved in reports, not in the real world.

How ecosystem services became the dominant language
In the late 1990s, a headline-grabbing study estimated Earth’s ecosystems to be worth tens of trillions of dollars, more than global GDP at the time. That single figure turned a technical concept into a mainstream storyline, inspiring economists, NGOs and development banks to treat nature as a giant service provider.
Forests, for instance, stopped being only timber. They became carbon sinks, water filters, mushroom pantries and tourism magnets. The hope was clear: if all of these benefits were tallied, a standing forest would “outperform” a clear-cut one in any serious cost–benefit analysis. Yet something vital was missing from those neat equations.
Closer inspection showed that the problem was rarely bad maths. It was power. Coastal communities might value mangroves as storm shields and fish nurseries, while a single company might see a profitable shrimp farm. Even when valuations showed higher total benefits for conservation, land still went to the actor with more influence.
Bold strategies that go beyond price tags on nature
Growing frustration with stalled sustainability targets pushed many scientists and activists to ask a blunt question: if putting prices on ecosystems is not enough, what comes next? Their answer increasingly leans towards bold strategies that tackle political and social forces head-on, not just their financial shadows.
In British Columbia, large conservation groups once leaned heavily on carbon credits and ecosystem service arguments to shield old-growth forests. Over time, they shifted towards a “climate justice” approach, forming alliances with First Nations and local communities to confront oil pipeline projects directly. Courtrooms, blockades and public pressure, not only spreadsheets, stalled the pipelines.
A new playbook for biodiversity protection
This pivot resonates with a wider move towards “biodiversity justice”. Rather than assuming that boardrooms and ministries are the only levers, conservation scientists now collaborate more with Indigenous leaders, farmers’ movements and labour groups. These alliances recognise that biodiversity protection depends on land rights, social equity and democratic control.
Research on nature-positive finance shows that integrating social justice into environmental policy can spur more lasting change than isolated market schemes. Studies such as the UN-backed assessments on the diverse values of nature, or detailed corporate analyses of nature-related risk, point to the same conclusion: who decides matters as much as what is counted.
For readers interested in how shifts in scientific narratives reshape history and policy, the story of the Beachy Head Woman, revisited through a groundbreaking DNA study, offers a striking example of evidence challenging long-held assumptions. Conservation faces a comparable moment of rethinking.
From natural capital to climate action on the ground
Despite its limits, the language of natural capital still shapes major climate and finance negotiations. Banks and insurers work to quantify the risks of ecosystem collapse. Governments trial “green GDP” metrics. Reports like The Lancet’s work on planetary health examine how poorly societies value nature in policy decisions.
This technical backbone is not useless. It can expose how much wealth depends on forests, wetlands or reefs. Yet data alone cannot deliver climate action. Without public pressure and legal safeguards, valuation can drift into greenwashing, where companies claim nature-positive portfolios while land conflicts intensify on the ground.
What bold strategies look like in practice
Several trends point towards a deeper, more grounded approach to environmental conservation. They shift the spotlight from market signals to political choices:
- Linking conservation to labour and social movements, so that protecting ecosystems also means securing jobs and fair livelihoods.
- Centering Indigenous and local leadership in land-use decisions, rather than treating communities as “stakeholders” to be consulted late.
- Rewriting fiscal rules so harmful subsidies for fossil fuels, deforestation and overfishing are phased out and redirected to nature recovery.
- Embedding legal rights for rivers, forests or species, giving ecosystems standing in courts and reshaping who can sue to prevent damage.
- Investing in long-term monitoring, using satellites and field science to track real ecological outcomes instead of only financial flows.
These moves do not abandon valuation; they put it in its place, as a tool serving democratic choice rather than a substitute for politics.
Why this matters far beyond conservation circles
The stakes of valuing nature correctly go far beyond endangered species lists. Food security, city flood defences, public health and even energy grids depend on living systems. Mangroves buffer coastal megacities from storms, peatlands stabilise water supplies, and pollinators prop up entire agricultural regions.
When those living infrastructures fail, the costs spread quickly across economies and borders. Businesses now map nature-related risks like they once mapped cyber threats. Families feel those risks when heatwaves intensify or fisheries collapse. In that sense, “planet rescue” is not a distant slogan; it is crisis management for the systems that keep societies functioning.
Why has putting a price on nature not stopped biodiversity loss?
Ecosystem service valuations often show that protecting forests, wetlands or reefs benefits society more than destroying them. Yet land-use choices are shaped by power, not only by numbers. When a small group controls territory and profits, decisions can ignore wider social and ecological value, even when the maths favours conservation.
Are ecosystem services and natural capital still useful concepts?
Yes, but only as supporting tools. They help reveal how much economies rely on healthy ecosystems and can guide smarter environmental policy. They become problematic when treated as a magic bullet or when financial metrics override justice, rights and local knowledge about the land.
What makes a conservation strategy truly bold?
Bold strategies confront root causes of damage: who owns land, who benefits from extraction, and whose voices count. They build coalitions between scientists, Indigenous communities, workers and citizens, combining legal action, advocacy and on-the-ground organising instead of relying only on market incentives.

People can back organisations that link biodiversity protection with social justice, support Indigenous land rights, and push for stronger climate action in local and national politics. Everyday choices matter, but aligning votes, savings and professional work with nature-positive policies has even greater impact.
Is there evidence that justice-focused approaches work?
Case studies from community-managed forests, Indigenous-protected areas and citizen-led climate lawsuits show higher conservation success and more durable outcomes. These examples suggest that when rights, accountability and participation are strengthened, ecosystems tend to recover and stay protected longer.
