Decimoputzu, a farming village in the lower Campidano

The countryside of the lower Campidano, the great plain of southern Sardinia, is flat and farmed, and Decimoputzu is part of it: an agricultural village about thirty kilometres from Cagliari. Fields, vineyards and orchards surround the built-up area, on almost level, low-lying ground.

In the centre you still find courtyard houses with a gateway onto the street, some of them built with the mud bricks (ladiri) typical of many Campidano villages. These houses need attention to rising damp and to the state of the walls, so have a surveyor look at them before making an offer. Around them are detached houses and newer homes. For work and services people look mostly towards the Cagliari area, almost always by car; the data record 22 services in the village itself.

In 2023 there were 4,170 residents, down 3.4% on 2011. The average age is 46.6, lower than the province (48.1), and over-65s make up 24.2%. Foreign residents account for 3.9%. Declared incomes are below the provincial average.

Like the whole of Sardinia, Decimoputzu is in seismic zone 4, the lowest class in the national classification drawn up by the Civil Protection department, and expected ground acceleration is about 0.050 g. Winters are mild (climate zone C) and summers hot, so roof insulation, shade and ventilation count for more than heating.

On the plain the hazard to watch is water. In heavy storms, channels and streams can overflow and flood the lowest areas, and the report checks the official maps for the chosen address. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the report also reaches the land parcel.

Overview

Decimoputzu is a municipality in the province of Cagliari, in Sardegna. At the end of 2023 it had 4,170 residents, ranked 24 of 70 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Decimoputzu 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 3.4%. The estimated average age is 47 years, lower than the province average (48). 24% of residents are over 65 (the regional figure is 27%). Foreign residents make up 3.9% of the population.
