Nature loss is being pushed out of the environmental box and into the risk register. According to the Government Actuary's Department, Georgina Bedenham, Head of Climate Risk and Disaster Risk Finance at GAD, has co-authored a new report arguing that actuaries, policymakers and financial institutions should treat damage to nature as a serious economic threat rather than a secondary concern. The report, Tipping into the Wild Unknown, sits within the Institute and Faculty of Actuaries' Planetary Solvency series. Its message is straightforward: if the natural systems that support food, water and health start to fail, the result will not stay confined to conservation policy. It will turn up in inflation, supply chains, markets and credit conditions.

The IFoA report makes a useful point for investors and business owners alike. Nature is not a nice-to-have around the edges of the economy; it functions more like basic infrastructure. Food production depends on healthy soils and pollinators. Water supply depends on functioning catchments and stable weather patterns. Public health and economic activity rest on those same foundations. That matters because financial debate often treats biodiversity loss as distant or hard to price. In practice, the route into household budgets is not difficult to see. If crop yields weaken, if water becomes harder to secure, or if pollinators decline, retailers and producers face higher costs. Consumers then meet the problem through dearer food, patchier availability and more volatile prices.

What gives the report its edge is the gap it identifies in current risk modelling. Climate risk has, slowly and imperfectly, made its way into board papers, stress tests and investor presentations. Nature risk has not kept pace. The Government Actuary's Department article notes that biodiversity-related threats remain largely absent from the models and scenarios used by governments, regulators and financial firms. For markets, that creates a blind spot. A lender may examine flood exposure while missing the effect of soil degradation on farm income. An investor may track carbon risk but not the pressure that water stress could place on food producers or manufacturers. That does not make the exposure smaller. It simply makes it easier to underestimate until it arrives in earnings, defaults or insurance losses.

The report points to risks that are already building rather than problems parked far into the future. Soil degradation, water stress and pollinator decline are all cited as threats to food systems now. It also warns about acute shocks such as breadbasket failures and trade disruption, which can feed quickly into price swings and wider economic instability. For households, that can mean the weekly shop becoming less predictable. For SMEs, it can mean more difficult stock planning, thinner margins and extra pressure on cashflow. A supermarket, food processor or café chain does not need a complete collapse in supply to feel the strain; repeated smaller disruptions can be enough to unsettle pricing and planning.

There is also a public health and macroeconomic angle that business readers should not ignore. The report says deforestation and land-use change raise the chance of animal-to-human disease spillover, a risk made painfully familiar by the COVID-19 period. When natural habitats are disrupted, the cost does not stop at the point of environmental damage; it can travel rapidly into labour markets, public finances and trade. Further ahead, the authors warn about tipping points such as the collapse of coral reefs or pollinator populations. Damage on that scale could be effectively irreversible on human timescales. That is why the report argues climate-only modelling is no longer fit for purpose. Climate change and biodiversity loss do not sit in separate boxes, and risk teams cannot keep treating them that way.

Bedenham's contribution is especially notable because it pushes actuarial practice beyond pure number-crunching. In comments published by GAD, she says actuaries should engage with emerging biodiversity metrics and quantification tools, but also use qualitative and narrative approaches alongside traditional models. That is a sensible shift. When the data are incomplete and the threats are linked, waiting for perfect precision can become a way of avoiding the issue. For Market Pulse UK readers, the practical takeaway is clear enough. Nature loss is no longer only an environmental story. It is a pricing story, a lending story and a supply-chain story. The firms that start treating it as part of mainstream risk management will be better placed than those still assuming it sits outside the balance sheet. Bedenham is also discussing the findings on The Actuary podcast, a sign that this debate is moving quickly into the financial mainstream.
