flects the large quality of resources that tourism consumes (space, energy, water etc.)
Agriculture and fishing
Since tourism dominates the Tenerifian economy, the service sector is the largest, but industry and commerce contribute 40% of the non tourist economy. The primary sector has lost its traditional importance in the island, to the industrial and service sectors. Agriculture contributes less than 10% of the island's GDP, but its contribution is vital, as it also generates indirect benefits, by maintaining the rural appearance, and supporting Tenerifian cultural values.
Agriculture is centred on the northern slopes, and is also determined by the altitude as well as orientation: in the coastal zone, tomatoes and bananas are cultivated, usually in plastic enclosures, these high yield products are for export to mainland Spain and the rest of Europe; in the drier intermediate zone, potatoes, tobacco and maize are grown, whilst in the South, onions are important.
Bananas are a particularly important crop, as Tenerife grows more bananas than the other Canary Islands, with a current annual production of about 150,000 tons, down from the peak production of 200,000 tons in 1986. More of 90% of the total is destined for the international market, and banana growing occupies about 4200 hectares. In order of importance; after the banana, come tomatoes, grapes, potatoes and flowers. Fishing is also a major contributor to the Tenerifian economy, as the Canaries are Spain's second most important fishing grounds.
