Biodiversity and natural capital

The indicator examines the series of data relating to forest areas affected by large fires on a national, regional and protected area scale over the period 2018 to 2024.

The distribution and extent of forest areas affected by fires generally show significant interannual variability. In particular, 2024 was a year less severely affected by the extent of forest areas impacted by fires compared to previous years. The forest area burned was higher only than that burned in 2018 and 2019, but significantly lower than all the years from 2020 to 2023.

In 2024, the most affected regions were Sicily (2,588 ha), Calabria (2,494 ha) and Sardinia (1,734 ha), which together accounted for 66% of the total national forest area affected by fires.

The most affected forest classes are evergreen broadleaved forests (e.g., holm oak woods and Mediterranean scrub), followed by deciduous broadleaved forests (e.g., oak and beech forests), and much less by coniferous forests (e.g., pine, fir, and larch forests).

Linear regression analysis of the national forest cover series affected by fires does not show an increasing trend, although the size of the series does not allow for medium- and long-term evaluations. A weak but statistically significant increasing trend was instead observed for the regions of Apulia, Basilicata and Calabria.

The phenomenon of forest fires analyzed based on data collected from 1970 to 2023 by the State Forestry Corps, now CUFA (Carabinieri Forestry, Environmental and Agri-food Unit Command), shows a fluctuating trend, with peak years (1993, 2007, 2017, 2021) alternating with years of decline (2013, 2014, 2018). The presence of fires within Protected Areas is high, with exceptionally large burned areas recorded in certain years, such as 2021 and 2022, when 26,507 hectares and 11,101 hectares were affected by fire, respectively.

The incidence of intentional fires is very high, accounting for approximately half of all recorded events and exceeding 60% in some years (2012, 2014, 2015, 2016, 2020).

The Natura 2000 Network in Italy consists of 2,646 sites, covering a total area, net of overlaps, of 5,845,078 hectares on land, equivalent to 19.4% of the national territory, and 2,301,047 hectares at sea, corresponding to 6.4% of territorial waters (data updated to December 2023). A total of 643 Special Protection Areas (SPAs) and 2,364 Sites of Community Importance-Special Areas of Conservation (SCI-SACs) have been designated (of which 361 are SCI-SACs coinciding with SPAs). In December 2022, the sites numbered 2,639, with an increase of 7 units in the past year and an expansion of 163 hectares on land and 229,358 hectares at sea. The coverage percentages of the Natura 2000 Network vary across Italian regions and autonomous provinces, ranging from 12% to 36% on land and from less than 1% to 30% at sea.

The national coverage of the Network is significant in relation to the targets of the EU Biodiversity Strategy for 2030 (SEB2030), which calls for expanding protected areas in the EU to reach at least 30% of terrestrial and 30% of marine areas. The SEB2030 target includes all areas subject to protection measures, such as Natura 2000 sites, National and Regional Parks, and other protected areas. At the regional level, Abruzzo and Valle d’Aosta meet the SEB2030 target, with Natura 2000 sites covering 36% and 30% of their territories, respectively. Other regions approaching the target include the Autonomous Province of Trento (28%), Molise (27%), Campania (27%), and Liguria (26%). The protection percentages of Natura 2000 marine sites are lower, with only Puglia (30%) and Tuscany (27%) having protection levels close to the target.

Soil degradation refers to the reduction in the biological productivity of soil resources. This process is often intrinsically linked to biodiversity loss and the impacts of climate change. Assessing soil degradation requires considering multiple interdependent factors, each contributing differently to the phenomenon.

In recent years, Italy has participated in the pilot project on Land Degradation Neutrality (LDN), promoted by the United Nations Convention to Combat Desertification (UNCCD), and in the LDN Target Setting Programme, which supports countries in identifying voluntary LDN targets and defining associated measures to achieve Sustainable Development Goal (SDG) 15.3. This goal is monitored through the "Proportion of degraded land over total land area" (SDG Indicator 15.3.1).

For the assessment of this indicator in Italy, three sub-indicators proposed by UNCCD under the LDN framework have been adopted:

1. Land cover change
2. Soil productivity index
3. Soil organic carbon content

Additionally, further indices and parameters relevant to the Italian context and available at the national level have been considered. The results show that in 2019, the proportion of degraded land in Italy, excluding water bodies, was 17.4%, according to the UNCCD methodology. Furthermore, nearly 56,000 km² (approximately 18.5% of the national territory) experienced increased degradation between 2006 and 2019.
