Selegas, wheat fields and the hills of Trexenta

Trexenta is an area of low hills and cereal fields in southern Sardinia, and Selegas is one of its farming villages. The village is compact, with the low courtyard houses typical of the Campidano and Trexenta, surrounded by fields, olive groves and a few vineyards. Senorbì, the largest town in the area, is close by, and Cagliari is reached by car along the main road.

Buyers mostly find village houses with an inner courtyard, some with older sections built of sun-dried earth bricks, and newer masonry homes. Earth-brick houses should be assessed by a surveyor who knows them: damp at the base of the walls and the state of the roof are the first checks. The climate is mild, zone C.

In 2023 there were 1,278 residents, according to Istat, the national statistics office, down 10.8% on 2011. The average age of 48.1 matches the provincial figure (48.1), and over-65s are 25.0% against 25.7%. Households have 2.48 members on average and foreign residents are 1.6%. Declared incomes are below the provincial average.

The earthquake picture is calm: all 70 municipalities in the province are in seismic zone 4, the lowest, and the expected ground acceleration in the village is 0.050 g.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for Selegas, so the report goes from the address to the land parcel. Among the hills, the beds of small streams can flood after heavy rain: the report checks the official maps for each address, along with distances to services.

Overview

Selegas is a municipality in the province of Cagliari, in Sardegna. At the end of 2023 it had 1,278 residents, ranked 48 of 70 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Selegas is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 70 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 10.8%. The estimated average age is 48 years, in line with the province. 25% of residents are over 65 (the regional figure is 27%). Foreign residents make up 1.6% of the population. On average, a household has 2.5 members.

How built-up it is

Radon and contaminated sites

Selegas is not among the radon priority areas designated by the Regione Sardegna in 2022. According to the ISPRA map, the estimated radon emission in the municipality is low. 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 Selegas: 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 Selegas 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 Selegas. Half of the residents live in areas scoring 71 or more.
