Rainfed / Irrigated Classification

Which fields are watered, and which depend on the rain.

Overview

Which cultivated fields are irrigated, and from which season onward?

Joint analysis of surface-moisture patterns from radar and greenness patterns from multispectral imagery, with climate covariates, flags the fields that are actively irrigated in the dry season. It is the basis of any water-allocation or groundwater-abstraction assessment, and it prevents the over-estimation of agricultural water use that comes from counting every cultivated hectare as irrigated.

    Rainfed (green) versus irrigated (cyan) parcels classified from combined radar and multispectral time series.

How it works

Pipeline and maturity of each stage

  1. 01

    Fused time series

    Operational

    Radar backscatter and optical indices are stacked per field across the season together with precipitation and temperature covariates.

  2. 02

    Irrigation signature

    Operational

    A field that shows surface moisture and active growth through the dry period carries the irrigation signature; the model learns it from field-verified labels.

  3. 03

    Classification and delivery

    Operational

    Each field receives a rainfed or irrigated class with confidence, aggregated to irrigated area by unit and delivered with a report.
