Agricultural Water Accounting

The integrated solution: from parcel map to water balance sheet.

In development

Integrated solution; parcel-mapping modules operational, water-volume and accounting layers in development

Overview

What was grown on each parcel, how much water did it use, and was that water worth it?

An integrated solution that chains the agriculture products into one answer for every parcel and season: what was grown, how much water it consumed, where that water came from, what it cost and what value it produced. Field boundaries, land cover, crop type and irrigation class build the parcel base map; a water computation engine turns crop, climate and thermal data into cubic metres per parcel; a financial layer turns volumes into cost, value and a water balance.

System architecture

Schematic of the main components, from inputs to delivered outputs.

Example outputs

  • Side-by-side satellite image at native resolution and after super-resolution

    Super-resolution makes small parcels resolvable before boundary extraction: native (left) and enhanced (right).

How it works

Pipeline and maturity of each stage

  1. 01

    Training-data tools

    Operational

    A geo-referenced field survey app and an image labelling environment produce labels for boundaries, land-cover classes and crop types, so the solution can be trained for any new region.

  2. 02

    Parcel base map

    Developed and evaluated

    Field boundary extraction, near-real-time land use and land cover, crop type classification and rainfed/irrigated classification, with super-resolution for small-parcel regions, produce every parcel's boundary, class, crop and irrigation type per season.

  3. 03

    Water computation engine

    In development

    FAO-56 Penman-Monteith reference evapotranspiration, crop coefficients per growth stage calibrated to the local climate, actual evapotranspiration from thermal imagery with surface energy balance models (METRIC / SEBAL), and effective rainfall give net irrigation requirement per parcel per season.

  4. 04

    Accounting and decision layer

    In development

    Volumes are joined with water-source and cost data to compute cost, value and profit or loss, aggregated from parcel to district, basin and national level in a seasonal water balance, a dashboard and a crop-pattern recommender.

Data used

  • Outputs of the agriculture products
  • Landsat and Sentinel thermal
  • Weather station and gridded climate data
  • Soil maps
  • Water-source and tariff data

Methods and models

  • FAO-56 Penman-Monteith
  • METRIC / SEBAL energy balance
  • Crop coefficients per growth stage
  • Spatial join of volume and cost layers

Outputs

  • Water volume in cubic metres per parcel per season
  • Cost, value and profit or loss of water used
  • Seasonal water balance at basin and national level
  • Dashboard and crop-pattern recommender

Who it is for

  • Water-resource management and over-abstraction detection
  • Economic valuation and pricing of agricultural water
  • Crop-pattern policy and planning
