WACAPOU (water awareness and compensation assessment program of optimum use) and green water

WACAPOU project (Water Awareness and Compensation Assessment Program for its Optimum Use) participates in reducing water footprint of activities focus on: · a measurable representative water footprint calculation · compensation solutions to replenish and/or maintain the freshwater resources. Green water is the biggest part of water, representing about 60% of rainfall. This is precipitation on land, not running off as opposed to blue water, but stored in the soil, evaporated, or transpired through plants. And it is not included into Water Footprint calculation. The Objectives of green water quantification: integrating green water into the water footprint calculation and promoting a local water cycle. The main difficulty is to measure green water in term of volume per unit of time. The aim of the work is to explore different methodologies proposed in the literature to establish a valid green water model based on remote sensing data (satellite images) and UAV (drone) acquisitions supported by field data in order to monitor different areas of interest.
