Il clima sta cambiando, l’agricoltura deve adattarsi e anche in Svizzera si cercano soluzioni. Agroscope ha annunciato lunedì che dalla scorsa primavera, e per almeno due anni, viene testata la coltura delle patate dolci. Questi tuberi, a differenza delle normali patate coltivate attualmente, resistono molto meglio a temperature più elevate e a climi secchi.
Condizioni meteorologiche estreme come quelle di quest’anno, infatti, diventeranno sempre più frequenti, secondo i climatologi.
Delle patate dolci piantate quest’anno sono sopravvissute solo quelle protette da una copertura in polietilene, le altre sono morte durante il calo delle temperature registrate a fine maggio. In molti sono interessati a questa produzione anche per motivi ecologici poiché una coltivazione locale eliminerebbe l’obbligo di importazione. Con il cambio di clima, in futuro potrebbe quindi cambiare anche il sapore del rösti.
