From credit to credibility: The importance of data verification

Katja Ravn van Overeem, Blayne Lees and Ben Smith
  1. 1

    Verifying the field boundary Farmers provide shapefiles and we verify the following:

    Is the field unique and is its area valid; does it overlap with any other field boundaries within our programme; is the field situated within arable cropland; has the field been deforested in the last 20 years; and has the field undergone transition from a natural ecosystem within the last 10 years?

  2. 2

    Verifying historical practices (i.e. historic tillage, cover cropping, fuel usage etc.)

    A process to ensure the farmer’s historic practice data is valid and correct using remote sensing, logic based checks, and farmer consultation.

  3. 3

    Verifying harvest and practice data from the current year (i.e. current tillage, cover cropping, fuel usage etc.)

    A process to ensure the farmer’s current practice data is valid and correct using remote sensing, logic based checks, and farmer consultation.

In this series, we're sharing an overview of what it's taken to build a carbon project that meets the highest of standards – Verra’s VM0042 methodology. This series of articles introduces the Agreena team that have worked closest to the project and continue to support the next steps to verification and issuance.

In this series you hear from:

  1. Karolina Kenney, Senior Standards Specialist; outlining the processes of building a project with the highest integrity for the market;

  2. Katja van Overeem, Blayne Lees and Ben Smith of the Data teams; explaining Agreena's work to ensure integrity of on-farm data capture at scale.

  3. Dr Petros Georgiadis, Dr Marcos Alves and Dr Andrew Manderson from the Agreena Science and Statistical teams; unravelling the methodology to calculate soil carbon credits through sampling and modelling together;

Roberta McDonald, Head of Programme
