Average agricultural yield per hectare of supplier individuals who sold to the reporting organization during the reporting period.
Organizations should footnote all assumptions used, including source of data, details on the group, and unit of measure reporting against (such as kilograms or bushels per hectare) using Unit of Measure (PD1602). See usage guidance for further information.
NOTE: This metric will be deprecated in a forthcoming update to the IRIS Catalog of Metrics. Users are advised to instead report Average Agricultural Yield (PI5935), applied to Supplier Individuals: Total (PI5350).
This metric is intended to capture the average output per hectare for farmers among an organization's suppliers.
Organizations should not calculate this metric using aggregate data across all suppliers. Rather, as noted in the calculation, organizations should use farmer-specific data. Organizations should report yield from the most the recent harvest and footnote details on the unit of measure.
This metric could be valuable for organizations that procure from farmers and provide support to improve their yields, such as training and technical assistance.
Organizations interested in reporting the yields of client farmers should report Average Client Agricultural Yield: Total (PI3468).
In some contexts, this metric can serve as an indicator of whether the outcome being sought by an investor or organization is occurring (the WHAT dimension of impact). For more on the alignment of IRIS metrics to the five dimensions of impact, see IRIS+ and the Five Dimensions of Impact (https://iris.thegiin.org/document/iris-and-the-five-dimensions/). No single metric is sufficient to understand an impact; rather, metrics are selected as a set across all dimensions of impact. When possible, the selection of metrics to measure and describe the five dimensions should be based on best practice and evidence.

IRIS Metrics Work Better in Sets
To use IRIS metrics—and the resulting data—to understand impact performance, IRIS metrics should be used and analyzed in generally accepted sets and according to well-defined objectives. IRIS+ gives you access to generally accepted Core Metrics Sets aligned to common Impact Themes and Sustainable Development Goals (SDGs).
