Cagliari metropolitan city (Italian: Città metropolitana di Cagliari) is one the Metropolitan cities of Italy. The metropolitan area is composed by the city of Cagliari and other 15 municipalities. [1] It covers about 1114 km² and has 422 308 inhabitants..

Geography[edit]

The Cagliari metropolitan city extends over the plain of Campidano and the first hills between two mountain ranges, at west side Monti Arcosu, Monti Lattias and Punta Sebera, at east side Punta Serpeddì and the Sette Fratelli mountain. These massive rocks are made up of very old Ordovician shale and Carboniferous granite and barely exceed the 1000 meters of altitude with a maximum in 1116 of Mount Is Caravius.. The city is spread over and around the hill of the historic district of Castello, and other nine limestone hills of the middle-late Miocene, unique heights of a little more than one hundred meters above sea level on the long plains of Campidano. The plain is actually a Graben formed during the Alpine orogeny of the Cenozoic, which separated Sardinia from the European continent, roughly where it is now the Gulf of Lion in France, and broke up with various up and down tectonic movements the ancient island Paleozoic skeleton.[2] It was covered by marine deposits of Miocene and alluvial deposits of Holocene. The repeated intrusion of the sea left calcareous sediments that formed a series of hills that mark the territory of Cagliari: that where there is the fortified town near the harbor of the port and the birthplace of the city, Mount Urpinu, the St. Elias hill, also known as the Sella del Diavolo ("Saddle of the Devil") for its shape, Tuvumannu and Tuvixeddu, where there was the ancient Punic and Roman necropolis, the small Bonaria hill, where stands the basilica, and the San Michele hill, on top of which is the eponymous castle. The modern city has occupied the flat spaces between the hills and the sea to the south and south-east, along the Poetto beach, the lagoons and ponds of Santa Gilla and Molentargius, remains of more recent marine intrusions, in an articulate landscape, with many landmarks panoramas on the bay, the plain, the mountains that surround it at east.

Climate[edit]

Cagliari and the Campidano plain has a Mediterranean climate (Csa in the Köppen climate classification) with hot, dry summers and very mild winters. The extreme values in summer sometimes slightly are over 40 °C (104 °F) (sometimes with very high humidity), while in winter, under special and rare conditions drop slightly below zero. Heavy snowfalls occur on average every thirty years.

The average temperature of the coldest month, January, is about 10 °C (50 °F), and those of the warmest month, August, about 25 °C (77 °F). But heat waves can occur, due to African anticyclone since June. From mid-June to mid-September, rain is a rare event, reduced to some storms in the afternoon. The rainy season starts in September, but the first cold days come in December, usually the wettest month as well.

Winds are frequent, especially the mistral and sirocco; in summer days a marine sirocco breeze (s'imbattu) lowers the temperature and the heat.

Demography[edit]

In the last century, the population of the municipalities of the metropolitan area increased by 354% and in the last 50 years by 158% (1911: 128,444; 1961: 288,683; 2011: 454,819). For the whole of Sardinia this increase respectively was 88% and 15% (1911: 868,181; 1961: 1,419,362; 2011: 1,639,362). The urbanization towards the area of Cagliari was, in percentage terms, impressive, making the capital of the island a metropolis surrounded by rural areas increasingly depopulated. This urbanization is also reflected in the concentration in Cagliari of most of the economic activities and wealth.

As for 2011 stranger population was only 10,837 people (2.38%) while the largest immigrant group were : Filipino, Senegalese, Romanians, Chinese, Ukrainians, Moroccans, Pakistani, Germans and others [4]

Economy[edit]

The traditional economy was based on agriculture, the cultivation of wheat, vineyards, olive groves, garden and orchards where there was plenty of water in the dry summer. The mountains were exploited for firewood and coal that were sold at Cagliari. There were also some mines, particularly the iron mine of San Leone in the territory of Assemini. And of course there were the large salt pans east and west of Cagliari.

Saras oil refinery

Nowadays in the capital city are concentrated most of the administrative tasks, the retail trade in the areas of the historical center, financial services and technology to business, professional offices, health services, while industries, warehousing services, major shopping centers are concentrated in the other municipalities of the metropolitan area and, along the coast, most of the tourist activities.

The Macchiareddu-Grogastru area between Cagliari and Capoterra, in conjunction with a large international container terminal port at Giorgino is the most important industrial area of Sardinia. Multinational corporations like Coca Cola, Heineken, Unilever, Bridgestone and Eni Group have factories in this area. Within its metropolitan area, at Sarroch, there is one of the six oil refinery supersites in Europe, Saras.

The communications provider Tiscali has its headquarters in the boroughs of the town, just near one of the biggest container terminals on the Mediterranean sea.

The metropolitan area of Cagliari is the wealthiest area of the island. According Eurostat,[5] the metropolitan area of Cagliari in 2009 had a per capita purchasing power standard (PPS) income of 21.699 euros, that is 92.4% of the European Union (27) data. In 2011 [6] the inhabitants of the metropolitan area returned an individual income tax per capita that was 96% of national average. The city of Cagliari returned 128% of National average, while entire Sardinia returned only 80%.

Metropolitan forests[edit]

Sette Fratelli mountains
Forested areas near Cagliari

The metropolitan area is limited to the east and west by high mountain ranges just over 1000 meters above sea level, largely covered by Mediterranean forests, dominated by evergreen oak, cork oak and arbutus. To the west the WWF nature reserve of Monte Arcosu lies, created to protect the subspecies of Sardinian deer (Cervus elaphus ssp. Corsicanus) and extended 36 km2 (14 sq mi), and the forests managed by the Ente Foreste of the Autonomous Region of Sardinia: Piscina Manna, Is Cannoneris, Monti Nieddu Gutturu Mannu for others 256 square kilometers; to the east Ente Foreste manages the Campidano Forest, and the forest of the Sette Fratelli ("Seven Brothers"), a vast massif with crested peaks that appear in the number of seven when seen from Cagliari (hence the name) and covers additional 132 km2 (51 sq mi).

The woods environment varies with altitude in both temperature and precipitation. In the municipality of Pula, for example, the coastal plain has an annual average rainfall of about 450 mm (18 in), while the mountains (Is Cannoneris, about 800 meters above sea level) have more than 1,200 mm (47 in). The forest is populated by the Sardinian deers (Cervus elaphus corsicanus), now saved from extinction, the fallow deer, reintroduced after its extinction, wild boars, foxes, European pine martens and others.

Metropolitan beaches[edit]
