Nuovi orti d’insalata in Liguria, ma non fanno parte del paesaggio poiché sono in fondo al mare. È cominciato infatti nella baia di Noli un particolare esperimento di coltura idroponica. Gli ortaggi sono piantati in soluzioni acquose nutritizie anziché nel terreno, all'interno di biosfere subaquee trasparenti.
Già l’estate scorsa un analogo esperimento, effettuato dalla Mestel Safety, aveva dato ottimi risultati con il basilico, al punto che una grande società aveva acquistato una biosfera per tentare un esperimento analogo in Arabia Saudita al fine coltivare un insalata molto apprezzata nel paese.
“Il test di idroponia in particolare è indirizzato a cercare una soluzione economicamente sostenibile”, spiega Sergio Gamberini, ideatore del progetto battezzato “L’orto di Nemo”, “il trasporto della terra per culture sott'acqua è oneroso, mentre la produzione di acqua dolce dalla desalinizzazione naturale sembra essere più percorribile.”
