MANAROLA, ITALY - 31 MAY 2017: Anselmo Crovara (82), the creator and custodian of the Memory Archive housed in his own attic (a collection of items from traditional Ligurian daily life), shows 1970s pictures of his mother who was one of the few women who had mastered the art of dry stone walls, here in his home in Manarola, Italy, on May 31st 2017.

Terraced vineyards, apple and lemon groves horizontally run around the green slopes of the Cinque Terre. The stone walls have allowed such vital cultivation in the area and prevented land slides. Since the 1960s, the ancient walls have been largely
abandoned, posing hydro-geological threats to the same villages during
heavy rains and, in general, as time passes.
Since the 2012 flood - when tons of mud invaded the
village’s main road, shops and and homes, isolating the area and
taking three lives - Margherita Ermirio has agreed with the various land lords to take
over 6,000 square meters of land parcels that needed to be cleaned up,
in order to fix them and thus prevent land slides, but also to show to
the younger generations that agriculture is still possible in the
