AGADAPT - Adapting the water use by the agriculture sector


STRATEAU is a tool of strategic analysis and outlook on water availability-demand balance over regional areas. It relies on a consistent database that combines structural characteristics of the territory and observed data. The reconstitution is homogeneous at different administrative and hydraulic scales, and for the different sectors addressed: agriculture, households, industries, services or energy.

Model architecture


STRATEAU includes two modules that interact thanks to allocation rules:

  • A resource part integrating a groundwater sub-model and a surface water sub-model
  • A demand part integrating an agricultural sub-model based on the CROPWAT method developed by FAO (Smith, 1992), and a generic sub-model for other sectors relying on unitary demand (per capita consumption), water demand determinant (population, employment…) and exogenous parameters (climate, equipment rate,…). Water demands are reconstituted following a bottom-up approach. Water demands are estimated for each sector at the minimal available space scale, generally being the municipality.














The outputs are available at four scales at a monthly time step:

  • Two hydrologic scales: river basin or sub-river basin
  • Two administrative scales: regional (country, region) or local scale (municipality)

Homogeneous estimations are carried out at the municipal scale by prorating data available at the hydrologic scale (and conversely). Calculations are later undertaken at the smallest available scale (sub-basin and municipality) and results are aggregated to provide a representation at the regional or at the river-basin scale, following a bottom-up approach.

Modele description:


Main processes being represented


In the demand module, water requirement are calculated based on unitary demands, determinants and exogenous factors. These requirements are then fulfilled from the available resources (direct withdrawals from surface or underground resources, drinking water network). Leakages as well as consumptive uses are integrated and allow calculating water discharges in the different water bodies.

In the resource module, aquifer recharge and river flows are impacted by withdrawals, leakages and discharges. Rainfalls are translated into runoffs to surface water and infiltration in aquifers based on Footprint SUGAR index, which estimates the probability of rainfall to infiltrate or to run-off with surface water[1].
