The Water Footprint for Skeptics
What do we count in the calculation of the Water Footprint (HH)?
In the first level how much water we apply to the crop, from pre-sowing to harvesting. We know this through the water meter. But this is not all, since this volume applied to the crop, we must subtract the volume of water that returns to the aquifer through drainage.
From here we can already understand that the Water Footprint is composed of the amount of water used for the production of a product, or service, that does not return to the "original source", in this case to the corresponding aquifer.
During the period of cultivation we use the raft, in it there is a continuous evaporation of water with more or less intensity, depending on the time of year. The evaporated volume is part of the use and is counted as part of the Water Footprint.
