MIL-150 Indicator Adoption — Agricultural Sector Update

This methodology note provides an update on the application of the AESA Master Indicator List (MIL-150) in the African agriculture sector. It examines disclosure adoption rates across five indicator categories — biodiversity, water management, smallholder livelihoods, land rights, and supply chain integrity — and identifies the structural data and capacity gaps that are preventing meaningful ESG disclosure by agricultural companies operating in African markets.

1. The MIL-150 Agriculture Sector Indicator Set

The AESA Master Indicator List (MIL-150)^[10] is a 150-indicator ESG assessment system covering nine African sectors. The agriculture sector indicator set comprises 22 indicators across five primary categories, calibrated to the specific materiality profile of African agricultural operations — including smallholder integration, communal land systems, water scarcity dynamics, and agrochemical intensity in African soil and climate conditions.

The agriculture indicator set draws from GRI 13 (Agriculture, Aquaculture and Fishing Sectors, 2021)^[1], the FAO Sustainability Assessment of Food and Agriculture Systems (SAFA) Guidelines^[2], the SASB Agriculture Standards^[3], and the Taskforce on Nature-related Financial Disclosures (TNFD) LEAP framework^[4]. It is calibrated to sub-Saharan African operating conditions, with indicator weights and assessment thresholds reflecting local regulatory requirements, infrastructure constraints, and stakeholder dynamics.

2. Biodiversity Indicators — The Critical Gap

Agriculture is the single largest driver of biodiversity loss globally, through land use change, agrochemical application, water extraction, and soil degradation. In sub-Saharan Africa, this dynamic is particularly acute: agricultural expansion is the primary cause of deforestation and habitat loss across the Congo Basin, the East African highlands, and the West African forest zone.

Despite this exposure, biodiversity disclosure by monitored African agribusiness companies remains at 12% meaningful adoption — the lowest of any indicator category in the MIL-150 agriculture set. The primary barriers are:

• Methodology gap: Most African agribusinesses have not adopted the TNFD LEAP framework, and biodiversity impact assessment requires specialist ecological survey capability that most companies do not have internally.
• Baseline data absence: Credible biodiversity impact disclosure requires pre-operation ecological baseline data. In many cases, this baseline was never collected, making retrospective impact assessment impossible without commissioned ecological surveys.
• Regulatory absence: Unlike water, where licensing requirements create reportable data, there are no equivalent regulatory biodiversity disclosure requirements in most African jurisdictions that would force data collection as a compliance by-product.

3. Land Rights — The Sensitivity Barrier

Land rights disclosure is the second-lowest performing category in the MIL-150 agriculture set. This reflects both structural data gaps and disclosure sensitivity. African land tenure systems are complex, often operating across formal and customary systems simultaneously, with community land rights that may be legally unregistered but socially recognised and economically significant. Agricultural companies operating on community land face difficult disclosure trade-offs: documenting the basis on which land was acquired, the community consultation process, and compensation arrangements involves acknowledging arrangements that may not meet international standards.

The practical result is that most agribusiness companies either disclose nothing substantive on land rights, or provide high-level CSR narratives about community relationships without the process and outcomes documentation that ESG-grade disclosure requires. International development finance institutions — particularly the IFC and AfDB — require land rights due diligence as a condition of project financing, creating a financing access risk for companies that cannot produce this documentation.

4. MIL-150 Calibration Considerations for 2026

Based on monitoring observations across the current reporting period, AESA is reviewing calibration adjustments in two agriculture indicator categories:

Deforestation-linked sourcing (Supply Chain Integrity): Following the European Union Deforestation Regulation (EUDR)^[8], which entered into force in 2023 and applies to commodities including soya, palm oil, cattle, coffee, and cocoa, supply chain deforestation disclosure expectations are increasing materially for African agribusiness companies exporting to European markets. MIL-150 supply chain indicators are being recalibrated to reflect EUDR traceability requirements for export-oriented companies.

Water stress context (Water Management): AESA's water management indicators are being updated to incorporate the WRI Aqueduct Water Risk Atlas^[7]'s sub-Saharan Africa water stress layers, enabling more precise calibration of water extraction and watershed impact indicators to local hydrological conditions.
