Grape production in Chile's Copiapo Valley could be down 30% in coming years due to recent flood damage.

About 988 acres of fruit in the valley were lost to the late March floods, according to a news release from the Santiago-based Chilean Fruit Exporters Association (ASOEX).

About 48% of acreage in the valley was affected by the floods, Lina Arrieta, president of the Copiapo Valley Agricultural Producers and Exporters Association, said in the release.

One worker died in the flooding and another is missing.

About 3,700 acres of production will only be salvageable if irrigation systems are fixed and channels cleaned soon, Arrieta said.

The Copiapo Valley is known for its production of early season grapes, which gives Chile a competitive advantage in international markets, Ronald Bown, ASOEX's president, said in the release.
