Giba, the lower Sulcis plain near the sea

In south-west Sardinia, Giba is a farming village in the lower Sulcis, on the plain that opens out between the inland hills and the coast. The sea is close, with the beaches and lagoons of the south-west coast a few minutes' drive away, while Carbonia is the largest town in the area for services, the hospital and public offices.

Houses are almost all low-rise, often with a courtyard, in a village built on flat ground. Alongside the homes of year-round residents there are summer houses and farmland with rural buildings, which need careful checks on access, utility connections and planning compliance. The climate is zone B, with mild winters and hot, dry summers, so heating costs little, while insulation against the heat matters.

There were 1,914 residents in 2023, according to Istat, the national statistics office, down 9.7% since 2011. The average age is high, 51.4 against 50.6 in the province of Sulcis Iglesiente, and over-65s are 32.0%. Foreign residents are 3.9%. Declared incomes are below the provincial average.

Earthquake hazard is in the lowest class: like the other 23 municipalities in the province, Giba is in seismic zone 4 on the Civil Protection scale, with an expected acceleration of 0.050 g. For a house near the streams on the plain, the official flood maps are more relevant, and the report checks them for the address.

The Revenue Agency's cadastral maps cover Giba too, so the report finds the land parcel from the address, which is especially useful for farmland with buildings.

Key points

  • Farming village in the lower Sulcis, near the coast.

Overview

Giba is a municipality in the province of Sulcis Iglesiente, in Sardegna. At the end of 2023 it had 1,914 residents, ranked 16 of 24 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Giba is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 24 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.050 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.

Population

Compared with the 2011 census, the resident population has fallen by 9.7%. The estimated average age is 51 years, in line with the province. 32% of residents are over 65 (the regional figure is 27%). Foreign residents make up 3.9% of the population. On average, a household has 2.0 members.

Income and climate

In tax year 2024, taxpayers in Giba declared an average taxable income of 16,886 euros, below the provincial average (19,085 euros). The Italian average is 24,895 euros.

Giba is in climate zone B, with 833 heating degree days: heating may be switched on from 1 December to 31 March, for up to 8 hours a day. The same table puts the town hall at 57 metres above sea level.

Public transport

We do not yet have open public transport timetables for this municipality: the report says so explicitly, without inventing distances.

How built-up it is

Buildings, roads, car parks and other sealed surfaces cover 4.0% of the land in Giba, compared with 3.4% in the region. In 2024 built-up land stayed almost the same.

Radon and contaminated sites

Giba is not among the radon priority areas designated by the Regione Sardegna in 2022. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Giba: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Land registry

The cadastral maps for Giba are public: from the address the report finds the sheet and parcel number.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 10 inhabited census areas in Giba. Half of the residents live in areas scoring 68 or more.
