In 1987 Lanzarote was declared one of the six universal models of sustainable development by the World Tourism Organization and in 1994 it was declared a Reserve of the Biosphere by UNESCO. Lanzarote is the most easterly of the seven major Canary Islands and lies in the Atlantic Ocean only some 100 km (60 miles) from the coast of Africa and 1,000 km from the Iberian Peninsula. The island enjoys an average temperature of 22ºC all year-round due to its advantageous location in the Tropic of Cancer Arrecife is the political and commercial capital and home to half of the island's population. Five minutes away is the international airport with its daily flights to the other Canary Islands as well as to mainland Spain and continental Europe. Lanzarote, including the small islands of La Graciosa, Alegranza, Montaña Clara, Roque del Este y del Oeste, covers 900 km² running 60 km north to south and only 20 km at its widest point. Lanzarote is made up of seven municipalities: Arrecife (the capital), Teguise, Haría, San Bartolomé, Tías, Tinajo and Yaiza, with an official population of nearly 100,000 inhabitants, mostly residing in the south-central part of the island. The island was named after a Genoese navigator called Lancelotto Malocello who arrived on the island during the second half of the XIV century opening the way to successive expeditions of French, British and Spanish sailors and merchants. Previously the isles were known as the Fortunate Islands. Fishing and agriculture once formed the basis of the island's economy but have since been overtaken by the excellent quality of its tourism industry. Amongst the most outstanding attractions are the Art, Culture and Tourist Centres run under the auspices of the Insular Council. The world famous artist César Manrique's sensitive response to Lanzarote´s unique geography and people was instrumental in creating a pervasive artistic identity throughout the island. Great care has been taken in preserving its historical and artistic heritage, its monuments and characteristic houses, local festivals and customs... in short, the full expression of its culture and folklore.
