Other mining activity includes salt, barite, crushed stone, peat and sand and gravel. Extensive exploration of offshore oil and gas has been undertaken in the past decade, and in 1991 the first commercial production of oil began near Sable Island. Nova Scotia has a highly specialized commercial agriculture sector. Dairy is the largest sector, followed by horticultural crops, poultry, eggs, beef cattle and hogs. Export commodities include blueberries, apples and processed fruits, vegetables and juices.
Tourism is an important sector in the provincial economy.
More than two million people visit the province each year, with almost one quarter of these coming from outside Canada. The province's physical location has made it well-suited for industry and trade. Harbour facilities, modern highways, air transportation, industrial parks, research and education facilities all contribute to providing a varied and positive climate for business.
