Rotterdam has the largest port in Europe, with the rivers Meuse and Rhine providing excellent access to the hinterland upstream reaching to Basel, Switzerland and into France. In 2003, Singapore took over, and in 2005, Shanghai, as the world's busiest port. In 2006, Rotterdam was the world's seventh largest container port in terms of Twenty-foot equivalent units (TEU) handled. The port's main activities are petrochemical industries and general cargo handling and transshipment. The harbour functions as an important transit point for bulk materials and between the European continent and overseas. From Rotterdam goods are transported by ship, river barge, train or road. In 2007, the Betuweroute, a new fast freight railway from Rotterdam to Germany, has been completed.
A highly mechanised agricultural sector employs no more than 4% of the labour force but provides large surpluses for the food-processing industry and for exports. The Dutch rank third worldwide in value of agricultural exports, behind the United States and France, with exports earning $55 billion annually. A significant portion of Dutch agricultural exports are derived from fresh-cut plants, flowers, and bulbs, with the Netherlands exporting two-thirds of the world's total. The Netherlands also exports a quarter of all world tomatoes, and one-third of the world's exports of peppers and cucumbers.
In the north of the Netherlands, near Slochteren, one of the largest natural gas fields in the world is situated. So far (2006) exploitation of this field resulted in a total revenue of €159 billion since the mid 1970s. With just over half of the reserves used up and an expected continued rise in oil prices, the revenues over the next few decades are expected to be at least that much.
