I due scoscendimenti con esito mortale in soli dieci giorni avvenuti in Ticino, hanno riaperto il dibattito: sul controllo del territorio, sulla mappatura delle zone a rischio e sulle cosiddette carte dei pericoli naturali.
Elisa Raggi ha contattato lunedì Arthur Sandri, direttore della sezione sezione "frane, valanghe e bosco di protezione" dell'Ufficio federale dell'ambiente. L’esperto ha spiegato che è compito del Cantone elaborare questi documenti per le zone edificabili.
Le carte devono quindi essere revisionate in caso di un evento come quello di Davesco-Soragno. Il caso di Bombinasco, invece, non è avvenuto in zona edificabile. Il Cantone potrebbe comunque decidere di mappare queste zone ma, spiega Sandri, “ci sono circa 30'000 rustici in Ticino. Sarebbe un lavoro enorme”.
