What is a nature dependency and why does it matter for business risk? A nature dependency is a measure of how vulnerable a business activity - or the production of a commodity - is to a change in an ecosystem service. While most companies focus on their impacts on nature, dependencies are the primary driver of physical risk. When an ecosystem service like water provision or pollination fails, it creates direct financial consequences, from supply chain disruptions to increased operational costs.
Why you should stop ignoring dependencies
Most corporate sustainability reporting has historically focused on impacts - what the company does to the environment. But as we discussed in our recent Behind the Metrics session, the finance and risk teams are increasingly concerned with what the environment does to the company.
If you only measure impact, you are only seeing half the story. You might have a low impact on a local water table, but if your entire production process depends on that water, a drought still creates a massive Value at Risk (VaR). Understanding dependencies is about identifying where your business model is inherently fragile.
How Natcap measures the transition from dependency to risk
We don't treat nature as a vague concept. We look at 19 specific ecosystem services - ranging from soil quality to flood protection - to determine how a business actually functions.
To move from a dependency to a physical risk, we look at three specific variables:
- Dependency Score: How much does this specific site or commodity rely on a nature-based input?
- Likelihood: What is the probability of a "change event" (e.g., a 1-in-100-year drought becoming a 1-in-10-year event)?
- Financial Consequence: If that service is lost or degraded, what is the actual bill? This is where we calculate the Value at Risk.
Making nature risk actionable for the board
The goal of this analysis isn't just to produce a report; it’s to put controls in place. Once you identify that a specific sourcing region has a "high-concern" dependency score, the conversation shifts from sustainability to strategy.
During the webinar, we outlined how organisations can use this data to:
- Prioritise Interventions: Focus your regenerative agriculture or restoration budgets on the sites where your financial exposure is highest.
- Inform Procurement: Use dependency mapping to identify which suppliers are most vulnerable to local ecosystem collapse.
- Build a Business Case: Present the CFO with a clear Value at Risk figure that justifies the investment in nature-positive actions.
The bottom line
Nature-related risk is no longer an externality. It is a core operational reality. By shifting your focus to dependencies, you stop treating nature as a compliance checkbox and start treating it as a fundamental pillar of business resilience.
