Combinando gli approcci basati sugli ecosistemi (EBA) con tecnologie digitali avanzate, SCORE ha contribuito a definire un quadro integrato per la gestione delle zone costiere, in linea con l'Accordo di Parigi. Un risultato chiave del progetto \u00e8 lo sviluppo di una piattaforma di allerta precoce basata su GIS e di un gemello digitale per supportare l'implementazione degli EBA, sbloccare nuove opportunit\u00e0 commerciali e migliorare la sostenibilit\u00e0 finanziaria delle citt\u00e0 costiere minacciate dai cambiamenti climatici. MBI ha svolto un ruolo chiave, contribuendo in modo significativo all'architettura e alla progettazione del sistema.<br \/>Siamo orgogliosi di aver fatto parte di questo importante passo verso un futuro pi\u00f9 sicuro e resiliente per le comunit\u00e0 costiere europee.<br \/>https:\/\/score-eu-project.eu\/2025\/06\/23\/scores-final-brochure-a-lasting-resource-for-coastal-climate-adaptation\/<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=\"1\" _builder_version=\"4.27.4\" _module_preset=\"default\" global_colors_info=\"{}\"][et_pb_row _builder_version=\"4.27.4\" _module_preset=\"default\" global_colors_info=\"{}\"][et_pb_column type=\"4_4\" _builder_version=\"4.27.4\" _module_preset=\"default\" global_colors_info=\"{}\"][et_pb_text _builder_version=\"4.27.5\" _module_preset=\"default\" global_colors_info=\"{}\"]L'evento si \u00e8 svolto nell'ambito della Conferenza europea sull'adattamento ai cambiamenti climatici (ECCA 2025) a Rimini, in Italia, uno spazio dinamico per presentare innovazioni, scambiare conoscenze e costruire partnership per promuovere un mondo resiliente ai cambiamenti climatici.
