- What needs to be estimated? Carbon sinks, avoided carbon loss, GHGs emissions, and mitigation co-benefits, e.g. water and biodiversity conservation, to ensure benefits to farmers
- How well? Accuracy and uncertainty
- How to reduce risks of impermanence or non-performance
- Scalability needs
- Frequency of estimations - reporting requirements, timing timing needed to detect changes (e.g. usually > 5 years) and make payments.
- Verification needs (e.g. first, second and third-party)
- How to minimize costs (e.g. acceptable % of the total project budget spent on MRV, sufficient benefit to farmers)
...
- Developing "green lists" of eligible practices (e.g. scientific literature review and experts consultation)
- Using models/remote sensing for accessing soil C sequestration magnitudes and trends: choosing a model, technical requirements, caveats, assumptions and uncertainties
- Moving to hybrid approaches: direct measurements with modeling/remote sensing
- Optimal measurement strategy based on project/region characteristics and resources available
- activity data collection (e.g. use of smartphone, interviews)
- focus on few high-quality measurements (e.g. what to measure and how - sampling design; soil C and soil bulk density; frequency)
- prioritization (e.g. sampling design; soil C or bulk density; soil C determination method; use of pedo-transfer functions,...)
- Dealing with data gaps (e.g. scientific literature, experts consultation, global databases)
- Choosing a model, model calibration, technical requirements and acceptable uncertainties
- Remote sensing: application and requirements
- Co-benefits assessment (e.g. generating water/biodiversity indicators from/in tandem? with soil C measurements)
- Optimal measurement strategy based on project/region characteristics and resources available
- Other MVR aspects
- Aggregation aspects across larger scales to reduce project-level variation effects
- Setting up baselines (e.g. Baseline v. base year)
- Verification type and frequency (credibility highest with third-party)
