Karnataka coffee, watershed evidence,
and three regulatory pressures stacking in 2026

1. The 2026 setup, in numbers

The headline rainfall numbers hide a sharper local story: Coorg has cycled through acute scarcity even in surplus-rainfall years because of micro-watershed timing and soil-moisture loss. Hassan recorded below-average rainfall in the same year. For a buyer reading an aggregate origin claim, "Karnataka 2025" tells you very little about which specific valleys are stable. That gap is exactly what watershed-level evidence closes.

2. Why coffee × Western Ghats is uniquely exposed

The Western Ghats coffee belt sits at the intersection of three sensitivities that no other commodity origin in India combines so densely:

• Hydrologically tightly coupled. Coffee — Arabica especially — needs reliable post-monsoon soil moisture. Failures don't just cut yield; they shift flavour profile and crop quality, which directly hits export grade.
• Forest-canopy dependent. Most Karnataka coffee is grown under shade with native or planted overstorey. The plantation is the forest as far as remote sensing is concerned — and as far as EUDR is concerned.
• UNESCO World Heritage adjacency. 39 Western Ghats sites are protected; buyer reputational risk attaches to any clearance signal, real or perceived.
• Smallholder structural fragility. The overwhelming majority of Indian coffee farms are smallholders. Compliance cost passed downstream lands disproportionately hard.

3. Three regulatory pressures stacking

4. What watershed-level evidence actually looks like

A defensible answer to all three pressures is the same dataset, organized three ways:

Question the buyer / regulator asks	What we put on the table
"Is this plot deforestation-free post-2020?" (EUDR)	Sentinel-2 NDVI history of the plot, 2020 → present, with cryptographic timestamps on each acquisition
"What is the water-yield profile of the watershed that supplies this plot?" (TNFD)	HydroBASINS Lvl 10 catchment + upstream forest mask + simplified water-balance estimate
"Has your shade canopy actually grown over the last 5 years?" (CCTS)	Year-over-year NDVI differencing + Sentinel-1 SAR backscatter for canopy structure
"How does the climate trend in this micro-watershed look?" (Investor / buyer risk)	IMD gridded rainfall + temperature trend, by basin
"Where is the verifiable audit trail?" (All three)	TPM 2.0 attestation + Merkle hash chain + RFC 3161 timestamps on every report

None of these inputs are proprietary. All come from free public sources we already integrate for the Japan pilot. The mapping for Karnataka is in our India pilot article.

5. A worked example: a hypothetical Kodagu exporter

Consider a mid-size Karnataka exporter shipping ~5,000 tonnes/year of washed Arabica into the EU, sourced from ~1,200 smallholders across Kodagu and South Chikmagalur. Their EUDR readiness work, today, typically looks like spreadsheets of GPS pins plus a verbal assurance that none of the plots was forest in December 2020. That is not enough to defend during a customs audit.

With the morimieru stack the same exporter produces, for each plot:

1. A 6-year NDVI track (2020 baseline through 2026 latest) showing no clearance event. Threshold-crossing alerts auto-generated.
2. A watershed signature — the upstream basin and its forest mask, with the water-yield estimate that feeds the plot.
3. A signed report bundle per plot, indexed by farmer ID, cryptographically chained, exportable as PDF for EUDR submission and as JSON for buyer ESG systems.

A realistic incremental cost per plot, using only free satellite data and our pipeline, is in the ₹50–₹200 / plot / year range for compute and storage. Compared to the consultant-driven alternative (₹2,000–₹10,000 / plot / year for less defensible evidence), the gap is structural.

6. Stack: what stays, what swaps

Layer	Source (already global)	India substitution
Optical satellite	Sentinel-2 L2A (Copernicus, 10 m, weekly)	—
Cloud-penetrating	Sentinel-1 SAR (Copernicus, 6-12 day)	Critical for southwest monsoon months
Climate	NASA POWER global	IMD gridded products for finer resolution
DEM	SRTM / Copernicus DEM	ISRO CartoSat where available
Watershed boundaries	HydroBASINS Lvl 10 (WWF, CC-BY)	India-WRIS for finer sub-basins
Forest inventory	—	Forest Survey of India (FSI) regional volume tables
Land-use baseline	—	ISRO Bhuvan LULC, FSI ISFR
Carbon methodology	IPCC AFOLU Tier 2	—
Credit registry	—	CCTS afforestation methodology · CAMPA projects

The architecture is the same one we run for the Himi (Japan) pilot. Only the regional reference layers swap. See the Tier 2 walkthrough for the CO₂ pipeline and the water-yield guide for the hydrology pipeline.

7. A 90-day pilot scope for a coffee exporter

Phase	Days	Output
1. Plot ingest	1–10	1,000–5,000 plot GPS coordinates loaded; buffer geometry standardized
2. Baseline build	11–25	2020 NDVI baseline computed for each plot
3. Time-series & alerts	26–45	2020 → 2026 NDVI tracks; clearance threshold alerts
4. Watershed signatures	46–60	Upstream catchment + water-yield estimate per plot cluster
5. Cryptographic chain	61–75	Per-plot signed reports (PDF + JSON), Merkle-rooted
6. EUDR export bundle	76–90	One-click export aligned with EUDR submission schema

We have not run this in India yet. We have run every piece of it for Japan, and we have documented the substitutions for India in the pilot article. The 90-day plan above is what we propose to a partner who can bring the plot list and a stake in the watershed.

8. Honest constraints

• Monsoon optical gaps. Sentinel-2 cannot see through clouds; the southwest monsoon period needs Sentinel-1 SAR composites to maintain continuity. The pipeline supports it, but cadence is coarser during those months.
• Smallholder plots are small. Sentinel-2 pixels are 10 m; a 0.5 ha plot is ~50 pixels. Fine boundary precision needs either airborne LiDAR or higher-res commercial imagery as a complement.
• Plot GPS quality varies. Smartphone-collected GPS can drift several metres. We document the input precision in every report so downstream auditors see the same uncertainty we did.
• EUDR scope is still moving. Implementing regulations have been refined repeatedly. Our export schema tracks the published version and is parametric.

9. Who this is for

• Karnataka coffee exporters / roasters who need to show a clean EUDR audit trail without paying consultancy rates per plot.
• F&B buyers sourcing Indian Arabica who want their own independent evidence layer instead of relying solely on supplier-supplied data.
• Coffee Board of India and the Karnataka Forest Department — for CAMPA / state-level monitoring of restoration credibility.
• CCTS project developers registering shade-tree restoration as afforestation methodology, needing baseline and MRV.
• Climate finance / impact investors evaluating Indian coffee-region exposure.

10. Frequently asked questions

Q1. Is morimieru EUDR-certified?

EUDR does not have a third-party certification scheme for monitoring providers. What matters is that the due-diligence statement is defensible — i.e. the spatial evidence, the dates, and the chain of custody. The cryptographic chain we layer on every report is designed exactly for that audit context.

Q2. Can satellites really distinguish a coffee plantation from primary forest?

Sentinel-2 NDVI alone cannot — both look dark green. But Sentinel-2 time series combined with Sentinel-1 SAR backscatter does. Coffee under shade has a distinct seasonal NDVI signature (harvest cycles) and a more structured SAR scattering than closed canopy forest. With FSI / Coffee Board plot polygons as labels, a state-level classifier reaches usable accuracy.

Q3. How does this connect to the EUDR's deforestation cutoff date?

The 2020-12-31 cutoff means we need NDVI evidence from a 2020 baseline through the shipment date. Sentinel-2 was already operational in 2020, so the baseline is real data, not modelled. The challenge is data assembly, not data existence.

Q4. We are a small exporter — is this only for big players?

No. The pipeline cost scales linearly with plot count. A 50-plot exporter pays roughly ₹2,500–₹10,000 / year for compute and storage, plus a one-time setup. The cost model deliberately favours smaller operators that consultancy-priced solutions exclude.

Q5. Will the same pipeline help us claim CCTS credits?

The same baseline NDVI and the same time-series differencing feed into a CCTS afforestation MRV report. CCTS registration itself goes through the Bureau of Energy Efficiency process; our role is the evidence layer.
