Oryza Labs by Praesidio Care · Rice methane MRV · Bengaluru · Singapore

We prove the methane that stayed in the soil.

Oryza Labs by Praesidio Care verifies methane reductions in smallholder rice — climate tech, not skincare. Rice paddies emit roughly a tenth of all human methane. Draining the field cuts that by half, and farmers save water doing it. Funding stalled for a decade on one missing piece: proof. We built it.

Methane is the fastest lever we have. Rice is the biggest one, and it has been stuck on measurement while the agronomy sat solved.

Oryza Labs by Praesidio Care builds rice methane MRV for carbon project developers, FPOs, and registries — plot-level proof that Alternate Wetting and Drying kept methane in the soil. Read who we are and how we differ from other brands named Oryza.

The record

The rice carbon market already collapsed once, on verification.

In August 2024 Verra invalidated 37 rice methane projects covering 4.5 million credits—roughly 99.9% of every rice credit ever issued—on additionality and verification grounds.

Read the full timeline on Verra's 2024 rice credit invalidation. Measurement is what stands between committed demand and verified supply.

Method

Four layers.

01

C-band SAR flood detection

Sentinel-1 detects standing water through monsoon cloud at ten metre resolution.

02

Sparse ground truth

A few hundred water-level sensors speak for a few hundred thousand hectares.

03

Flux model

Flooding regime converts to per-plot methane, Gold Standard aligned.

04

Plot-level uncertainty

Honest confidence bounds. The error bar is what a registry buys.

Where we are

Early, and saying so.

TRL 3. Pre-seed. Our Sentinel-1 pipeline classifies field-level flooding across a validation district over one growing season. Ground calibration starts Q1 2027. We sell independent verification—not bundled origination.
