What are tiers?
Tier 1
Estimate using own judgement and observations
Tier 2
Estimate using third-party professional estimates or public data
Tier 3
Model or measure based on site-specific surveys/sampling, remote or in-field sensing, laboratory analysis, etc.
Example data sources
Internal records
Third-party data sources
Site-specific measurements or model outputs
Notes
Note that this metric is the inverse of what is commonly termed ‘yield’ (mass of product output per unit area of land).
Variants of this metric include TNFD. Food and agriculture additional disclosure metric FA.A4.1: “Land use efficiency (ha land/kg of product).” and FA.A3.0: “Actual and potential yield (kg/km2), and yield gap, by type of crop.”

Notes
This measure may be derived from ecosystem asset condition accounts (see Ecosystem assets). Relevant soil quality variables may include any of the physical, chemical or biological characteristics of soils that enable soils to provide ecosystem services. Impacts on soil quality may also be measured indirectly, e.g. by using % bare ground or % productive land with retained stubble as a proxy for exposure of soils to erosion and/or loss of nutrients.
Variants of this metric include TNFD. Food and agriculture additional disclosure metrics FA.A5.2: “Proportion (%) of land with soil degradation in the total area of agricultural production, including soil erosion, reduction in soil fertility, salinisation of irrigated lands and waterlogging.”; FA.A5.5: “Antimicrobial residue in the soil (nano/milligrams per kilogram of soil).”; FA.A5.6: “Soil bulk density, measured as the ratio of a soil’s dry mass and its volume (g/cm3).” and FA.A5.7: “Soil organic carbon (tC).”
