Ugotovil je, da se nekatera polja preve\u010d namakajo, kar je zelo potratno. Ali bi bilo mogo\u010de s pomo\u010djo satelitov ugotoviti, katera polja resni\u010dno potrebujejo vodo?

Z analizo odbitih signalov satelitske navigacije je Javier ugotovil, da je mogo\u010de izmeriti, koliko vode je na tleh pod njimi: v tleh, snegu, na mokri\u0161\u010dih in celo vi\u0161ino vode v rezervoarjih. Ti signali lahko razkrivajo, katera polja potrebujejo zalivanje in katera so v redu tak\u0161na, kot so.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1920\" data-credit=\"Divirod\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2017\/05\/Irrigation_systems_like_this_sprinkle_water_over_fields\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2017\/05\/irrigation_systems_like_this_sprinkle_water_over_fields\/18248067-2-eng-GB\/Irrigation_systems_like_this_sprinkle_water_over_fields.jpg\" alt=\"Irrigation systems like this sprinkle water over fields\"><figcaption>Tak\u0161ni namakalni sistemi razpr\u0161ujejo vodo po poljih<\/figcaption><\/figure>\n<p>V naslednjih nekaj mesecih bo ve\u010d kmetov te podatke uporabilo za nadzor koli\u010dine vode, s katero zalivajo svoja polja.
