Biodiversity & Economic Value — Dasgupta Review, Natural Capital, TNFD, Business Risk & 30×30
Biodiversity — the variety of life on Earth at the genetic, species, and ecosystem level — underpins all human economic activity. Approximately $44 trillion of economic value generation (more than half of global GDP) is moderately or highly dependent on nature and its services: pollinators for agriculture, freshwater from forested watersheds, coastal protection from mangroves and reefs, disease regulation from intact ecosystems, and genetic resources for pharmaceutical and agricultural innovation. Yet biodiversity is declining at rates unprecedented in human history: the Living Planet Index (WWF/ZSL) shows an average 69% decline in monitored vertebrate populations since 1970. The primary drivers — land use change (agriculture, deforestation), direct exploitation (overfishing, hunting), climate change, pollution, and invasive species — are all linked to economic activities. The Dasgupta Review (2021, commissioned by UK Treasury) was the first comprehensive government-commissioned economic analysis of biodiversity, equivalent in scope to the Stern Review on climate change. It argued that the global economy is liquidating natural capital — running down its stock of "produced, human, and natural" capital — and that market failures (underpricing, externalities, perverse subsidies) are the root cause. Policy responses now include the Kunming-Montreal Global Biodiversity Framework (COP15, December 2022), which set the 30×30 target (protect 30% of land and ocean by 2030), mandatory corporate biodiversity disclosure through TNFD (Taskforce on Nature-related Financial Disclosures, launched September 2023), and biodiversity net gain requirements for development. The challenge is making biodiversity economically legible — creating the accounting systems, metrics, and financial incentives that make natural capital visible in corporate and government decision-making.

Drivers of Biodiversity Loss
Land use change (agriculture)Dominant driver globally; ~50% of habitable land surface now agricultural; conversion of tropical forests, grasslands, wetlands; commodity supply chains (soy, beef, palm oil, timber) drive ~80% of tropical deforestation; IPBES: #1 biodiversity threat
Direct overexploitation (hunting, fishing)~33% of fish stocks overfished (FAO 2022); legal and illegal wildlife trade; bush meat hunting; coral reef overexploitation; second-largest driver; interacts with other threats to push populations below recovery thresholds
Climate change (rising role)Third overall but accelerating; at 1.5°C: 6% insects, 8% plants, 4% vertebrates lose >50% of range; at 2°C: doubles; polar species (Arctic fox, polar bear), coral, alpine species most threatened; climate-biodiversity nexus becoming dominant
PollutionNitrogen and phosphorus runoff from agriculture causing freshwater eutrophication and ocean dead zones; pesticides: neonicotinoids linked to insect-apocalypse/pollinator collapse; plastic pollution; light and noise pollution affecting migration/reproduction
Invasive species350+ vertebrate extinctions attributable to invasive species since 1500; rats, cats on islands; zebra mussel in Great Lakes; chytridiomycosis fungal disease eliminating amphibians globally; globalised trade accelerating spread

Valuation — Methods & Controversies
Why valuing nature is necessary — and contested: The Dasgupta Review argued that the economic invisibility of nature — its exclusion from GDP, corporate balance sheets, and market prices — is the root cause of biodiversity loss. But valuing nature in monetary terms is deeply contested: critics argue it commodifies and monetises something intrinsically valuable; supporters argue it is the only language that penetrates economic decision-making.
Regulating services (most valuable)Climate regulation (carbon sequestration), water purification (forests as natural water treatment), flood regulation (wetlands), disease regulation (intact ecosystems limit zoonotic spillover), storm protection (mangroves, reefs): together worth ~$30–50T/yr (Costanza et al. 2014)
Pollination services ($235–577B/yr)IPBES 2016: 75% of leading crop types depend on animal pollination; commercial value of pollination-dependent crops: $235–577B/yr globally; decline in wild pollinators (not just honeybees) threatens agricultural productivity
Pharmaceutical value~50% of pharmaceutical drugs derived from or inspired by nature; penicillin (fungus), taxol (Pacific yew), artemisinin (sweet wormwood), aspirin (willow bark); genetic diversity in wild plant relatives crucial for crop breeding (disease resistance)

Natural Capital Accounting — What It Measures
Moving beyond GDP: The Dasgupta Review's central argument was that GDP is a deeply flawed welfare measure because it measures production flows but ignores the stock of natural capital that produces those flows. A nation that clear-cuts its forests earns timber income (GDP rises) while depleting the asset that produces the income (natural capital falls). Natural capital accounting — as developed through the UN SEEA framework — attempts to measure this stock alongside produced capital (machinery, buildings) and human capital (skills, knowledge).

TNFD — Nature Disclosure Framework
What TNFD is: The Taskforce on Nature-related Financial Disclosures (TNFD) was established in 2021 as the nature equivalent of TCFD (climate). Its framework (launched September 2023 after 18 months of beta development) provides recommendations for how companies and financial institutions should report on their nature-related risks, opportunities, dependencies, and impacts.
LEAP approachLocate (identify interface with nature), Evaluate (dependencies and impacts), Assess (risks and opportunities), Prepare (strategy and targets and reporting); four-stage process for materialising nature risk assessments similar to TCFD climate scenario analysis
320+ early adopters (Sept 2023)AXA, BNP Paribas, HSBC, Nestlé, Unilever, Nuveen, Tesco among early adopters; financial sector leading; manufacturing and food/agriculture following; TNFD aligned with GRI and ISSB standards for integrated reporting
Biodiversity credits (emerging)New asset class: credits representing measurable biodiversity outcomes (species, habitat, ecosystem condition); UK Biodiversity Net Gain credits (mandatory from 2024); voluntary biodiversity credit pilots (Terrasos, Wallacea Trust, Plan Vivo); less developed than carbon credits; additionality and permanence challenges

Target 2 — RestorationRestore 30% of degraded ecosystems by 2030; EU Nature Restoration Law (2024) — legally binding 20% of land and sea area under active restoration by 2030; controversial (farming lobby vs. environment); passed EU Parliament 2024
Target 18 — Harmful subsidiesEliminate, phase out, or reform $500B/yr in biodiversity-harmful subsidies by 2030; most ambitious but least enforceable GBF target; agricultural subsidies (CAP, US Farm Bill), fisheries subsidies, fossil fuels all implicated; "identify and reform" language only

The Dasgupta Insight — nature as an asset, not just a service: The most powerful idea in the Dasgupta Review (2021) is that nature is not just a bundle of "ecosystem services" (water purification, carbon sequestration, pollination) that can be valued and protected individually — but a complex, interconnected system whose resilience and productivity depend on its integrity as a whole. Piecemeal valuation of individual services — paying farmers for carbon sequestration here, protecting a wetland for flood regulation there — cannot substitute for maintaining the underlying ecological complexity that generates all services simultaneously. This argues for a fundamental shift from "payment for ecosystem services" to "maintaining natural capital stock" — which requires changing how we measure prosperity (accounting for natural capital depletion alongside GDP), how we regulate (prohibiting destruction of irreplaceable natural assets rather than allowing it to be "offset"), and how we finance nature (instruments that reward long-term stewardship of complex ecosystems rather than single-metric outcomes). The 30×30 target, TNFD disclosures, and biodiversity net gain requirements are first steps — but the Dasgupta framework suggests the transformation needed is as profound as the transition away from fossil fuels.
