The Cool Farm Tool Water metrics provide a water assessment of crops
showing the blue and green water footprint*
*COMING Q2 2017
With 70 percent of fresh water globally consumed by agriculture, farmers and supply chains are often called on to provide assessments of water used for crop production and ensure efficiency.
quick and easy
Water footprints can be cumbersome and data intensive. But the Cool Farm Tool water metrics enable farmers to quickly and easily account for their crops’ water needs and gain insight into better practice.
Minimal data entry, maximum output
Behind the scenes, the tool combines just a few additional user inputs with global data sets for crop, soil and climate data, to provide crop water estimates.
Find out if you over or under irrigated. Compare water applied with estimated requirements based on global datasets. Optimal water can mean optimal yields, meaning all resources – both natural and financial – are used most efficiently.
Put the focus on what you can do
Try out management options like irrigation type and increasing soil organic matter to see how to improve water retention and make the most of each drop of water applied.
This is just the beginning
Future releases will compare crop water footprints to water scarcity/availability in the region, include more crops and more management options to consider, and provide calculations to inform water catchment policies.
Measure and reduce your water footprint with the CFT:Create an account
(I) Determining atmospheric forcing defined as evapo-transpiration of a short, well watered grass. This is done using an adjusted form of the Penman-Monteith equation.
(II) Scaling the reference evapotranspiration with a crop factor that is dependent on crop.
(III) Adjusting the crop factor for local climate and soil conditions as well as determining water stress based on soil water availability.
The Cool Farm Tool Water advances FAO56 by improving the simulation of soil water dynamics (e.g. including runoff, interception, the
effect of organic matter). All three steps are included in Cool Farm Tool Water and linked to global datasets for climate (ERA Interim), soil (Harmonized World Soil Database and FAO56) and crops (FAO56).
The tool can currently represent farm management by simulating different crops, different irrigation methods and accounting for different soil properties as soil organic matter as well as texture.
