Ecosystem services
Ecosystem services are the contributions nature makes to people: pollination of crops, regulation of floods and water quality, fisheries, timber, carbon storage and cultural value. Economies depend on them in ways that rarely appear on balance sheets until they fail. This page sets out how dependencies on nature are mapped, how service supply is modelled and accounted, and how the loss of a service propagates to livelihoods, firms and financial institutions.
Ecosystem services on the record.
Ecosystem services: how the risk develops.
Pollination, flood buffering and livelihood dependencies. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Supply depends on condition
A service exists only where an ecosystem supplies it and people benefit from it. Pollination needs pollinator habitat near crops; flood buffering needs floodplains upstream of settlements. Mapping supply, flow and demand separately avoids counting services nobody receives.
Dependencies are hidden
Firms depend on water, pollination, soil fertility and climate regulation through their suppliers, often several tiers removed. Sector tools map which activities depend on which services, but location decides how material a dependency is.
Loss travels through supply chains
Fewer pollinators lower yields of dependent crops; degraded catchments raise water treatment costs; lost mangroves raise storm losses. The shock moves through prices, insurance claims and loan performance to sectors far from the site.
Risk reaches finance
Nature-related risk reaches financial institutions as physical risk from service loss, transition risk from regulation and market shifts, and systemic risk when losses correlate. Supervisors are examining how these risks enter credit, market and insurance exposures.

Ecosystem services are the couplings, named and measured.
| Service | Domain it supports | How it is measured |
|---|---|---|
| Water regulation and purification | Water: catchment hydrology | Avoided treatment cost; baseflow contribution |
| Pollination and pest control | Food: agricultural production | Yield dependence on pollinators |
| Climate regulation | All domains | Carbon stocks in tonnes per hectare |
| Disease regulation | Health: One Health | Change in transmission with habitat change |
| Coastal protection | Infrastructure and settlements | Wave attenuation by reefs and mangroves |
IPBES’s framing of nature’s contributions to people (Díaz and others, 2018) and its Values Assessment (2022) caution that monetary valuation captures only some values; the UN SEEA Ecosystem Accounting records services in physical and, where appropriate, monetary terms. The TNFD recommendations (2023) ask companies to disclose dependencies on these services.

Ecosystem service evidence.
Ecosystem service accounts and dependency analyses are designed for the Country Systems Risk and Resilience series; financial disclosure questions are taken up by The Global Risks Alliance (GRA) within its own boundaries. Useful contributions: national ecosystem accounts, local valuation studies and critiques of valuation methods.
Model ecosystem services as a system. Run the cascade.
Assembled from the Nexus Standards area profile Biodiversity and nature risk standards: the hazards it names, the systems and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.

What experts ask.
Researchers on ecosystem services ask where benefits come from and who relies on them.
- Which ecosystems supply which services, and how does supply change with condition?
- Who uses the service, where, and what substitutes exist if it declines?
- How sensitive is service supply to thresholds, for example in pollinator abundance or wetland area?
- How do changes upstream or upwind affect beneficiaries far away?
- When does valuation help decisions, and when does it hide distributional or cultural losses?
From ecological function to human benefit.
A service exists where an ecological function meets a human need. Pollination becomes a service where insect-pollinated crops are grown within the foraging range of pollinators; flood buffering becomes a service where a wetland lies upstream of homes and infrastructure. Supply depends on ecosystem condition and configuration; demand depends on where people are and what they do. Mapping both, and the flow between them, is the core of the field.
Losses transmit through production, prices and public budgets. Reduced pollination lowers yields or raises costs of managed alternatives; degraded catchments raise water treatment costs; lost coastal habitat increases damage and the need for engineered defences. Effects fall hardest on those without substitutes, which is why dependency analysis looks at distribution as well as totals.
How the evidence is built, and where it stops.
- 01
Service mapping
Spatial models of supply, demand and flow with geospatial information systems. Many rely on land-cover proxies that miss condition.
- 02
Biophysical modelling
Process models estimate water regulation, sediment retention or pollination. They need local data to be credible.
- 03
Valuation
Economic methods estimate value in money where markets do not. Results vary widely with method, and some losses cannot be meaningfully priced.
- 04
Dependency assessment
Mapping which sectors and communities depend on which services, drawing on complex systems modelling. Dependency is not the same as financial materiality.
