The three-tier monitoring stack
Kokonut’s MRV methodology operates across three complementary sensing tiers. Each one captures what the others cannot — satellite imagery misses ground-level soil chemistry; soil probes miss landscape-scale vegetation patterns; community analytics capture agronomic judgment that sensors cannot encode.On the ground sensing
- Soil Moisture Probes
- Community Analytics
- Technologies & Digital Tools
Soil moisture probes are installed across the farm to provide continuous subsurface readings across three dimensions:
- Volumetric Water Content (VWC): Determines the amount of water present in the soil relative to its total volume — providing accurate measurement of moisture levels across different soil layers and flagging irrigation needs before they become visible above ground.
- Electrical Conductivity (EC): Measures the soil’s ability to conduct electricity, the primary proxy for soil salinity and nutrient availability. Rising EC over time indicates salt accumulation; declining EC after biochar application indicates improving nutrient retention.
- Soil Temperature: Records soil temperature in °C — a critical variable for biological and chemical processes affecting plant growth, germination timing, and microbial activity in the root zone.

Satellite imagery from Landsat 8 and Sentinel provides landscape-scale vegetation health data at regular intervals — Sentinel overpasses every 5 days at 10m resolution. Drone surveys with Pix4Dcapture supplement satellite passes at higher spatial resolution for specific plots.Vegetation index selection guide
Four indices are used, each suited to a specific crop condition. Index selection is not arbitrary — applying the wrong index at the wrong crop stage produces misleading readings.| Index | Formula | When to apply |
|---|---|---|
| NDVI | (NIR − RED) / (NIR + RED) | Throughout the production season as the primary vegetation health baseline. The most widely used index in remote sensing — accurate when canopy cover is established. Avoid during early establishment when bare soil exposure is high. |
| ReCI | (NIR / RED) − 1 | During the active vegetative development phase. Responds directly to chlorophyll concentration — a proxy for nitrogen availability. Use when growth rate and leaf color are the key monitoring variables. |
| NDRE | (NIR − RED_EDGE) / (NIR + RED_EDGE) | During the crop maturity phase, when the canopy is closed and NDVI begins to saturate. More sensitive than NDVI to chlorophyll variation in dense, closed-canopy crops. |
| MSAVI | (2 × Band4 + 1 − √((2 × Band4 + 1)² − 8 × (Band4 − Band3))) / 2 | At the beginning of the crop production season when seedlings are establishing and bare soil exposure is highest. Designed specifically to minimize soil background interference on crop health readings. |

Normalized Difference Vegetation Index: The most common vegetation index in remote sensing. Applied throughout the crop production season as the baseline health indicator.
Values range from −1 to +1. Dense, healthy vegetation approaches +1. Bare soil clusters near 0. Water bodies are negative. A declining NDVI trend over successive satellite passes is an early warning of drought stress, disease, or nutrient deficiency — before visible symptoms appear.
From measurement to verification — the EAS pipeline
Collecting data is a measurement. Submitting it to the Farm Registry is reporting. Making it verifiable means anchoring it on-chain so that no party — including Kokonut Network itself — can retroactively alter what was recorded. Every MRV submission follows this pipeline:Data collected
Ground probe readings, satellite vegetation indices, and community field logs are assembled into a structured MRV payload matching the
KokonutMRVPayload schema — farm_id, timestamp, measurement_type, and the relevant tier object (ground, remote, or community).Payload pinned to IPFS
The full MRV payload is pinned to Filecoin/IPFS before submission. The returned content identifier (CID) is immutable — the same data will always produce the same CID, and the CID cannot be generated from different data. This is the content address that the on-chain attestation will reference.
Submitted to Farm Registry API
The payload is submitted to
POST /farms/{farm_id}/mrv on the Farm Registry API. The API returns a mrv_id UUID and sets is_attested: false — The event is recorded but not yet verified.EAS attestation created on-chain
After the MRV event is recorded, an EAS attestation is created on Gnosis Chain or Base — encoding the
farm_id, event_type, ipfs_cid, impact_score, attestor_role, and timestamp. The attestation is cryptographically signed by the attestor wallet and anchored permanently on-chain. The attestation UID is then submitted to POST /farms/{farm_id}/attestations, linking the on-chain record to the Farm Registry event. The MRV event is updated to is_attested: true and becomes immutable.Data appears on the Data Hub
Once attested, the MRV event appears in the farm’s public record at hub.kokonut.network/projects/41 — queryable by anyone, traceable to the on-chain attestation, and permanently part of the farm’s verifiable impact history.
The Kokonut × AI Agents page documents how this pipeline is being automated — AI agents ingesting satellite data, calculating vegetation indices, submitting to the Farm Registry API, and creating EAS attestations automatically on each Sentinel overpass cycle, removing the manual bottlenecks that currently limit MRV frequency.
Ecological impact tracking
Kokonut tracks and reports on environmental and social impacts using the EBF Framework for Environmental and Social Impact Reports. Impact is measured across four GHG and ecological dimensions, with methodologies specific to Kokonut’s farm operations.- Methane (CH₄)
- Nitrous Oxide (N₂O)
- Carbon Sequestration
- Ocean Impact
Why it matters: Methane has approximately 80 times the warming potential of CO₂ over 20 years. Agricultural methane sources include livestock digestion and poorly managed manure. Kokonut methodology:
- Using seaweed-based organic fertilizers (seaweed supplementation has shown significant methane reduction in ruminant digestion)
- Collaborating with local farmers to incorporate seaweed into cow feed as a methane-reduction intervention
- Free-range poultry management at Adelphi — poultry manure is processed into humic acids and organic urea rather than stored in anaerobic conditions that produce methane
Annual reporting
MRV data aggregates into annual impact reports across four dimensions, aligned with the EBF Framework and queryable via the Farm Registry API’s/impact endpoint.
| Dimension | What is measured | Key metrics |
|---|---|---|
| Environmental | Ecological health and carbon performance | Annual carbon sequestration rates (t CO₂e/acre), NDVI averages across the growing season, changes in local biodiversity indices, MRV event count |
| Economic | Financial impact on farmers and communities | Gross revenue, public goods allocation distributed (10% of revenue), jobs created and sustained, household income changes |
| Social | Community wellbeing and capacity | Community workshops held, participants trained, women in leadership roles, educational program reach |
| Sustainability | Long-term resilience across all 8 forms of capital | Annual sustainability audit across Natural, Financial, Social, Human, Material, Intellectual, Cultural, and Health capital; organic certification status; SDG attestations |
