GrapeLook usessatellite remote sensing techniquesto measure the water released by plants, the increase in biomass and the yield with which water resources are being used. All this information, once processed, is distributed to winemakers and hydrological authorities through a web page based on Google Maps.
The platform was put to the test this year with the collaboration of a group of South African winemakers, who could periodically access the system to check the status of their crops, receive estimates of the soil moisture level and learn about the irrigation needs of their farms. All participants agree that GrapeLook was very helpful in monitoring crop growth, identifying irrigation problems, and avoiding drought. All of this information helped them find more efficient irrigation methods and reduce workload and other costs. As a last resort,this system will help to increase the number of grapes harvested and the quality of the wine, saving water.
“The GrapeLook service is a good example of how space technology can help farmers,” explains Annemarie Klasse, land and water use specialist at WaterWatch. “Not only does it help reduce water consumption, it also increases production and ensures sustainable harvests. The next step will be to expand the service to other crops and other regions.”
