Through analytics: measuring the Nature Relationship Index

Hangzhou, where the lake meets high-rise towers and camphor trees line the promenade, frames a pivotal question for modern development. The Nature Relationship Index seeks to shift the gaze from raw growth metrics to the quality of the bond between people and the living world. This is not a marginal recalibration of indicators; it is a redefinition of progress that treats living systems as active partners in human flourishing, not externalities to be managed or external costs to be tolerated. The pursuit is to quantify a relationship that is at once ecological, social, and political, and to do so with transparency that invites accountability from policy, markets, and civil society.

Why now? Because the global economy still marches to a GDP tempo that hides ecological debt and social vulnerabilities. Yet data availability and computational power have reached a threshold that allows a composite signal to travel across borders with credibility. The Nature Relationship Index translates a complex web of interactions into a narrative that can be read alongside established measures like the Human Development Index, but with a focus on landscapes, cities, and ecosystems as living, breathable components of prosperity. This shift changes the stakes: the index asks not only how rich a country is, but how well it sustains the living world that sustains prosperity, including biodiversity, rivers, forests, and the ecosystems that weave together climate resilience, food security, and health outcomes.

In early formulations, the index rests on three core dimensions, each with its own evidence base and policy implications. These dimensions are not isolated checklists; they interact, creating feedback loops that can amplify or dampen development trajectories. The ambition is to produce a simple, intuitive framework that remains scientifically rigorous when unpacked. The result should be a metric simple enough for annual reporting, yet nuanced enough to reveal hidden tradeoffs in global supply chains and urban form. The ambition is not to worship nature as a constraint but to recognize nurture as a capital that nations can grow through careful stewardship and intelligent design for co-flourishing.

The West Lake moment makes this debate tangible. A landscape of cultivated harmony, it embodies a long history of nature integrated with civilization, where water, hills, and human-made structures form a living mosaic. The index uses such mosaics as a reference point for what flourishing looks like on a national scale, translating mystique into measurable components. The overarching aim is to avoid romantic nostalgia while embracing the ethical imperative to steward life-support systems in the face of rapid development, globalization, and technological diversification.

Two practical anchors guide implementation. First, the index must be visible, annual, and comparable across countries. Second, it must respect complexity without becoming indecipherable. These constraints drive a structure that stakeholders can trust, including policymakers, researchers, and civil society leaders. The result is not a forecast but a diagnostic and aspirational instrument, designed to reveal where societies are thriving and where they are loosening the bonds that connect people with nature, ecosystems, and climate stability.

This is not a celebration of nature in abstraction. It is a call to reimagine development as a shared project of survival and renewal, where economic power does not extinguish ecological memory or social equity but allocates space for living systems to flourish alongside human achievement.

Conceptual framework

The Nature Relationship Index draws on a simple premise: human wellbeing emerges from a living world that remains diverse, connected, and resilient. It places the living world at the center of development, rather than at the periphery, and treats nature as a co-creator of prosperity rather than a passive input. The framework rests on three interlocking dimensions that together define a nations capacity to co-flourish with the living world.

• Thriving and accessible nature in landscapes and cities: rural mosaics that support biodiversity, and urban green spaces that improve health, climate regulation, and social equity.
• Care for nature in practice: reduction of material and energy footprints, sustainable supply chains, and responsible consumption that respects habitat integrity.
• Safeguards for the future: protected areas, water and air quality, and long-run resilience against climate and biodiversity risks.

These dimensions are not a simple sum; they interact dynamically. A country can raise one dimension while slipping in another, creating uneven development. The index seeks to illuminate these patterns, offering a map rather than a single destination. It also acknowledges trade-offs: a country with high urban greenness might still demand emission-intensive inputs from abroad, or vice versa. The measurement approach tracks such trade-offs through data that connect domestic decisions to global ecological footprints, making the hidden distances visible across borders.

To operationalize the framework, the team considers a suite of indicators spanning land use, biodiversity indicators, water quality, air quality, protected area coverage, and urban green infrastructure. It pairs these with indicators of emissions, habitat fragmentation, and the sustainability of consumption pathways. The combination aims to reflect both the living world and the human economy, invoking ecological integrity, social equity, and climate resilience as mutually reinforcing elements of development. The result should enable cross-country comparisons that are meaningful to policymakers and to citizens who experience daily life in cities and forests alike.

Dimensions in practice

In practice, the three dimensions require careful balance. The nature thriving dimension emphasizes the state and accessibility of ecosystems, including habitat diversity, climate regulation services, and public access to nature. The care dimension centers on reducing negative impacts, including the embodied carbon of consumption and the ecological footprints of imports and exports. The safeguarding dimension emphasizes long-term protections and environmental quality, such as fresh water, clean air, and sediment and nutrient cycles that sustain life across generations.

The project explicitly engages with data limitations. Not every country has robust, annual metrics for every indicator. When gaps exist, the approach uses transparent imputation methods and clear communication about uncertainty, while prioritizing indicators with broad coverage and comparability. The goal is to produce an annual ranking that is robust enough to guide policy and simple enough to be understood by people outside the scientific community, so that the concept of flourishing with nature becomes a shared public good rather than a technical novelty.

Through contrast: how NRI diverges from GDP and HDI stories

The Hangzhou workshop underscored how the Nature Relationship Index can reveal counterintuitive truths that GDP and even HDI miss. A country’s wealth or general health does not automatically guarantee a high level of co-flourishing with the living world. Conversely, a nation with moderate income and robust ecological stewardship can outperform richer peers on the three dimension test when landscapes remain ecologically diverse and urban nature is widely accessible. This contrast matters because policy signals often rely on one-dimensional metrics. The NRI pushes for a multi-dimensional understanding that aligns economic performance with ecological integrity and social welfare.

Consider a high-income country whose prosperity rests on highly destructive supply chains or intensive resource extraction. Even with strong urban amenities, such a country can rank poorly on care if its consumption patterns externalize damage to distant ecosystems. The same logic applies to urban centers that achieve high GDP per capita but fail to provide livable, green, and equitable cities. The NRI does not punish wealth; it probes how wealth is generated and how its production and consumption reshape landscapes, biodiversity, and water quality across scales. It reframes success as a balanced attainment across the three dimensions rather than a single financial index.

In contrast, some mid-income or lower-income contexts may perform well on the NRI if nature persists as a source of livelihoods, pollinator networks sustain agriculture, and cities offer accessible green space. A country can sustain diverse habitats, avoid excessive habitat loss, and maintain water and air quality, thereby supporting long-term resilience even if current incomes trail behind wealthier peers. The index highlights these disparities and invites policy attention to where nature-based strategies can compensate for limited fiscal capacity, such as ecological restoration, community managed forests, or urban greening programs that deliver economic and health co-benefits.

Urban form matters a lot in this contrast. A city with a generous tree canopy, safe parks, and waterways that support fisheries or recreation tends to align more closely with the care and thriving dimensions. In contrast, a concrete metropolis with traffic, heat islands, and limited public green space may fail to translate prosperity into lived well-being for residents. The index allows such urban realities to be weighed against national outcomes, encouraging a more nuanced discussion about the city as a site of both ecological risk and opportunity. The contrast is not merely aesthetic; it is a diagnostic of structural choices that determine whether growth serves life-support systems or erodes them.

Crucially, the NRI should not be mistaken for a nostalgia for a preindustrial past. It recognizes that human capability is a planetary force whose consequences unfold through global trade, technology, and policy choices. The point is to ensure that development trajectories account for ecological costs and distribute gains more equitably across generations and geographies. In this sense, the index acts as a bridge between the old wisdom about living in tune with nature and the new data-driven governance models that increasingly shape global normalization of policy priorities. The ambition remains to align human welfare with the integrity of living systems, not to trade one for the other.

Counterfactuals and boundary conditions

The index framework includes a set of boundary conditions to prevent misinterpretation. It must not reward poverty or penalize prosperity in ways that encourage dysfunctional governance or eco-dictatorship. A collapsing state may show a low ecological footprint but offers little to none of the conditions necessary for long-term flourishing. Likewise, a country with healthy ecosystems but weak institutions can risk a fragile transition if governance fails to protect nature or distribute social benefits. The NRI seeks to reward combinations that sustain nature while maintaining or improving human well-being, but it also flags structural fragility when institutions are weak or when governance incentives misalign with ecological goals.

Through cause-and-effect relationships: pathways linking nature and human flourishing

Developing a robust causal narrative between nature and human well-being is essential for credible policy design. The Nature Relationship Index does not pretend to reduce this complexity to a single adjustable parameter. Instead, it emphasizes causal pathways, feedback loops, and potential unintended consequences that arise from policy choices, trade, and technology. A core idea is that flourishing with nature emerges when ecological conditions, social equity, and governance capacity reinforce one another, creating virtuous cycles rather than destabilizing trade-offs.

One important pathway runs from the state of landscapes to health and productivity. When biodiversity thrives and habitats remain connected, pollination services and pest control improve crop yields, while clean water supports human health and economic activity. This, in turn, reduces healthcare costs and increases labor productivity, reinforcing investment in nature-based solutions such as restoration and nature-based infrastructure. The causal chain is not linear; it includes delays, thresholds, and context-specific dynamics that require careful monitoring and adaptive management. The NRI is designed to illuminate these linkages rather than pretend they are always straightforward.

Another key pathway concerns urban nature and social equity. Access to parks, street trees, and blue-green corridors can mitigate heat stress, improve mental health, and foster social cohesion. These benefits accumulate over time, raising a citys liveability score and enabling greater human-capital formation. The policy implication is clear: invest in urban nature not as a luxury but as a capital project that reduces long-run costs and expands inclusive participation in the benefits of development. When nature and equity advance together, the locus of prosperity shifts from elite enclaves to broad-based opportunity.

Trade, supply chains, and embodied environmental costs offer a more distant causal pathway with large implications. Consumption patterns in one country can drive habitat loss in another through land-use change, deforestation, and emissions embedded in imported goods. The NRI makes these distant connections legible, enabling policymakers to pursue demand-side interventions that reduce leakage of environmental damage to overseas ecosystems. The aim is to create alignment between domestic policy and global ecological realities, so that a nations wealth does not come at the expense of distant living systems. This requires data integration across sectors and scales, something the index design explicitly seeks to enable.

Finally, governance and institutional capacity influence all causal chains. Transparent reporting, independent verification, and credible enforcement mechanisms increase trust in the NRI and the actions it motivates. When policy decisions reflect a credible, data-driven understanding of living-system dynamics, communities gain confidence in long-term planning, and private actors adjust incentives toward sustainable practices. The result is a governance environment where ecological integrity, social welfare, and economic opportunity reinforce one another rather than compete for priority. The Nature Relationship Index is thus a tool for steering complex systems through informed, values-based choices that acknowledge the interdependence of life-support systems and human life.

Through expert reconstruction: building a policy architecture for the NRI

What would it take to operationalize the Nature Relationship Index in national policy and international reporting? The Hangzhou workshop highlighted three core design principles. First, the metric must remain simple enough to communicate while preserving scientific integrity. Second, it must be adaptable to data disparities across countries by providing clear uncertainty statements and transparent methodologies. Third, it should empower decision-makers to translate rankings into concrete actions that preserve living systems and advance human well-being in parallel. The architecture must balance ambition with pragmatism, ensuring that policy recommendations remain actionable and credible across different governance contexts.

A practical governance model combines annual reporting with policy guidance, much like the Human Development Index has done for decades. The Nature Relationship Index would publish a country ranking, accompanied by a dashboard of trend indicators, hotspots of ecological stress, and target regions for improvement. It should invite cross-national learning, enabling countries to compare strategies that preserve or restore habitats, expand urban green space, and recalibrate consumption patterns. The data transparency is critical: governments and independent researchers should access the same underlying data to verify results and propose improvements, strengthening public trust and accountability.

Policy implications extend to budgetary allocations, regulatory reforms, and cross-border cooperation. For example, nations with significant biodiversity can align their development plans with habitat protection and restoration, creating new opportunities for green jobs, sustainable agriculture, and nature-based climate solutions. In countries heavily reliant on fossil exports, the NRI can incentivize diversification, encourage sustainable sourcing, and invest in urban nature as a resilience strategy that protects health and livelihoods. The instrument thus becomes a compass for transitions, not a punitive metric that penalizes prosperity or romanticizes poverty. Its true value emerges when it helps shape smarter, greener development pathways that align with a shared planetary boundary framework and the principles of intra- and intergenerational equity.

Implementation challenges are real. Data gaps, political volatility, and competing policy priorities can all impair the reliability and usefulness of the index. The Hangzhou discussions emphasize the importance of building a robust data ecosystem, including satellite-based landscape monitoring, biodiversity inventories, and transparent supply-chain traceability. The index should support iterative improvement, with mechanisms to revise indicators as technology and knowledge advance. It should also encourage stakeholders to co-create definitions of flourishing that resonate within diverse cultural contexts while preserving scientific rigor. The goal is to establish a globally shared, locally actionable framework that turns numbers into meaningful strides toward a more harmonious, sustainable future.

As this work advances, its potential influence extends beyond academia and policy circles. Public-facing communication matters: narrative framing, visualizations, and accessible storytelling can translate abstract indicators into concrete, everyday understanding. The table of contents, dashboards, and annual rankings should illuminate not only where a nation stands but what it can do next, guiding urban planning, natural-resource management, and education. The aspiration is to cultivate a shared language about development that honors the living world as a partner in human achievement, generating a global conversation about how to build a resilient, equitable, and flourishing future for all species that share this planet.

In the end, the West Lake remains a symbol of a deeper civilizational question: how to align human aspirations with the poetry of nature. The Nature Relationship Index invites a practical answer: measure, reflect, and act in ways that expand the living worlds capacity to support wellbeing. If the index succeeds, it will not distill complexity into a single number alone but change what societies notice and value. Indicators shape attention, and attention shapes aspiration. Aspiration, over time, sculpts landscapes and futures that prioritize life as the core asset of development, not its byproduct.

Undoubtedly, this is a work in progress. The Hangzhou workshop represents a moment in the ongoing dialog among ecologists, development economists, historians, and policy practitioners. It demonstrates a shared conviction: that the path to sustainable prosperity requires a clear articulation of how humans relate to the living world and a credible method to monitor that relationship. The Nature Relationship Index aims to make that relationship legible, navigable, and able to guide a planetary civilization toward a future where flourishing with nature is achievable for everyone, everywhere, and for generations to come.

As the living world continues to respond to human action, the index will evolve. But the core idea remains: a good relationship with the living world is not a constraint on growth but a necessary condition for durable, inclusive prosperity. If we seize this opportunity to reframe progress around flourishing with nature, the next generation may look back on this moment as the turning point when humanity began to measure success not solely by wealth or health alone, but by the quality of our entanglement with the rest of life on Earth.

In this sense, the Nature Relationship Index aligns with a long tradition of civilizational thinking that seeks harmony between heaven and humanity, between field and city, between policy and practice. The challenge is to translate that harmony into governance, markets, and everyday choices that sustain the living world while allowing human communities to thrive. The work in Hangzhou underscores that this is possible, and that a planetary horizon does not preclude a local, tangible, and humane future for all species that share our world.

Ultimately, indicators shape attention, and attention shapes aspiration. The ambition is to convert aspiration into tangible action, cultivating landscapes, cities, and economies that honor the living world as a partner in prosperity. If the Nature Relationship Index succeeds, it will invite a broad coalition to steer development toward mutual flourishing, a horizon in which the success of nations is measured by the vitality of the living world as much as by the wealth it generates.

Notes: This essay reflects a collaboration between the Leverhulme Centre for Nature Recovery and Aeon. It distills a week of intense dialogue in Hangzhou into a forward-looking framework that couples empirical rigor with aspirational storytelling. The aim is to foster a shared language for a global policy conversation about how to live well with the rest of life on Earth, while acknowledging the complexities and uncertainties inherent in any large-scale transition.

End of draft

To address the most pressing practical limitation, the missing piece is a compact toolkit that translates NRI signals into concrete actions with accountable owners and timelines across cities, sectors, and nations. This section adds a core, action-oriented layer: a concise indicator table, a domain-wide action deck, and a scenario that shows tangible payoffs, all anchored in the three NRI dimensions — thriving nature, care for nature, and safeguards for the future.
