TNFD Tools Catalogue — Africa Mining Filter

v1 publication 13 May 2026 (v1.0.59 deploy) · Editorial responsibility: Nikesh Patel · Status: PUBLISHED — companion to Methodology §10.4 TNFD biodiversity substrate.

What this catalogue does. Taskforce on Nature-related Financial Disclosures (TNFD) emerged from 2023 and is increasingly embedded in DFI environmental and social due diligence. This catalogue surfaces the five TNFD-aligned tools most applicable to African mining decision contexts, with Tier-1 / Tier-2 / Tier-3 applicability classification per asset type and primary-source authority each tool publishes. Per Methodology §10.4 TNFD substrate.
v1.0.60 framing caveat. Authority and Access claims per-tool below are drawn from public-source overview understanding of each tool. Specific organizational composition claims (e.g., DEG as WWF Water Risk Filter co-developer; specific Alliance organization rosters; subscription/free-tier framings) should be primary-source verified against each tool's current public documentation before institutional use. The framework structure and tool-applicability matrix below are stable; specific authority attribution carries Inferred state pending primary-source verification.

Tier-1 tools (material for greenfield + ESIA-active assets)

WWF Water Risk Filter TIER 1

Geographic + sector water-risk assessment across physical / regulatory / reputational dimensions. Africa-relevant for assets in water-stressed basins (Limpopo, Orange, Cunene, Cuvelai-Etosha) and high-irrigation-demand catchments (Senegal, Niger, Volta).

Authority: WWF + DEG (German DFI) joint development  ·  Access: Free public web application  ·  Africa-mining relevance: Greenfield project siting + operating water-stewardship reporting

IBAT (Integrated Biodiversity Assessment Tool) TIER 1

Globally consistent biodiversity intelligence: IUCN protected areas, Key Biodiversity Areas (KBAs), Important Bird Areas (IBAs), species ranges. Africa mineral provinces overlap multiple high-biodiversity zones (Congo Basin, Eastern Arc, Cape Floristic Region, Albertine Rift).

Authority: IBAT Alliance (BirdLife / Conservation International / IUCN / UNEP-WCMC)  ·  Access: Commercial subscription; project-screening API available  ·  Africa-mining relevance: IFC PS6 alignment, ESIA biodiversity baselines, IFC EHS Guidelines for Mining biodiversity offset substrate

ENCORE (Exploring Natural Capital Opportunities, Risks and Exposure) TIER 1

Natural capital dependency + impact framework for financial sectors. Maps economic activities to ecosystem service dependencies (water provision, climate regulation, pollination, soil quality) and impact drivers (water use, GHG, terrestrial ecosystem use, soil pollutants).

Authority: Natural Capital Finance Alliance (NCFA): UNEP FI + Global Canopy + UNEP-WCMC  ·  Access: Free public web application  ·  Africa-mining relevance: TNFD-aligned dependency/impact framing for institutional reporting

Tier-2 tools (relevant for operating + corridor assets)

Aqueduct (WRI Water Risk Atlas) TIER 2

High-resolution water-risk atlas: baseline water stress, water depletion, groundwater table decline, drought / flood / coastal flood risk projections. Africa-mining-applicable for water-stressed Cu-Co operating context (Lufilian Arc), water-budget-tight Au operations (Birimian), and infrastructure-corridor route planning.

Authority: World Resources Institute (WRI)  ·  Access: Free public web application + API  ·  Africa-mining relevance: Operating asset water-stress reporting, TNFD water-related risk disclosure

Global Forest Watch TIER 2

Near-real-time forest cover change monitoring + supply chain deforestation risk. Africa-mining-applicable for Congo Basin deforestation context (Lualaba, Tanganyika, Western Lufilian operations) and miombo woodland operations (Mozambique Belt, Congo Craton).

Authority: World Resources Institute (WRI)  ·  Access: Free public web application + API  ·  Africa-mining relevance: EU CSDDD / Deforestation Regulation supply-chain context, TNFD location-based disclosure

Counterparty Extension preservation

This catalogue references each tool only through its public-source authority and application context. No claim that any tool maintainer (WWF, WRI, IBAT Alliance, NCFA) has reviewed any Afrimintel asset assessment or endorsed any Afrimintel methodology. Tool outputs cited per dossier carry Quality Standard three-state tagging (Pending where tool query is deferred to verification cycle).
