OECD - Environment at a Glance
L'Organizzazione per la Cooperazione e lo Sviluppo Economico (OECD) ha predisposto questo core set di indicatori per valutare le prestazioni ambientali nei paesi e per monitorare il percorso verso lo sviluppo sostenibile. Questi indicatori forniscono messaggi chiave sulle principali tendenze ambientali in settori quali il cambiamento climatico, la biodiversità, le risorse idriche, la qualità dell’aria, l’economia circolare e le risorse oceaniche.
Sono presenti gli indicatori ISPRA che hanno una corrispondenza (non sempre univoca) con gli indicatori “di natura ambientale” del suddetto core set.
In alcuni casi, a un singolo indicatore del core set ISPRA corrisponde uno o più indicatori del core set in questione, o viceversa, più indicatori del core set ISPRA corrispondono a un singolo indicatore del core set di riferimento.
Italy hosts a remarkable floristic heritage, both in terms of species and subspecies richness (2,815 lichens, 1,209 bryophytes, and 8,241 native vascular entities) and biogeographical value. Of the 8,241 Italian vascular plant,1,702 species (equal to 20.65%) are endemic, meaning they exist exclusively in the country. Among these, 1,128 species are regionally endemic, with their range restricted to a single Italian region (data updated to April 2024).
The indicator also highlights the IUCN risk status of 2,430 vascular plant entities (representing 29.5% of Italy’s vascular flora), identifying the main threats affecting them. Unfortunately, the overall conservation status cannot be considered satisfactory: 2.2% (54 species) of the 2,430 evaluated entities are extinct or likely extinct; 24.3% (590 species) are at risk of extinction.
Human-induced pressures related to land-use changes represent a major driver of plant species extinction risk. The Red List of vascular flora identifies the most critical pressures affecting species: Modification of natural systems (39% of the 2,430 assessed taxa are subject to this pressure);
Agricultural development (27%); Residential development (27%); Direct human disturbance in natural environments (20%).
The indicator provides an overview of the current presence of alien animal and plant species in Italy through quantitative data, showing the temporal trends of introduction in Italy over the last century, the average annual introduction rate (average number of new alien species introduced each year), the pathways (according to CBD categories), and the distribution of invasive alien species of Union concern. The number of alien species in Italy is progressively and constantly increasing. Based on currently available data, nearly 3,800 exotic species have been introduced into our country, of which 3,659 are currently present in the territory. The average number of species introduced per year has increased exponentially over time, increasing from 6 species/year in the 1970s to 16 species/year in the last decade,reaching nearly 30 species/year in the current decade. The cumulative number of species introduced in Italy since 1900 also confirms this exponential trend, with an increase of over 500% in 120 years.
The indicator measures the amount of waste sent for biological treatment, specifically composting, integrated anaerobic/aerobic treatment, and anaerobic digestion. In 2022, the total amount of waste recovered through biological treatment processes (approximately 8.4 million tons) showed no significant variation, with a slight increase of 47,000 tons (+0.6%) compared to 2021. However, the share of organic waste, which decreased from about 6.8 million tons to approximately 6.7 million tons (79.6% of the total treated), saw a decline of around 132,000 tons (-1.9%), mainly due to a lower contribution of biodegradable waste from garden and park maintenance.
In 2022, the amount of incinerated municipal waste, including RDF (Refuse-Derived Fuel), dry fraction, and bio-dried waste derived from municipal waste treatment, amounted to 5.3 million tons (-1.9% compared to 2021). Of this waste, 71.4% was processed in Northern Italy, 9.5% in Central Italy, and 19.1% in Southern Italy. The majority of incineration plants are located in the North (25 facilities), while Central and Southern Italy have 5 and 6 operational plants, respectively.
In 2022, the total national municipal waste (MW) production in Italy amounted to approximately 29.1 million tons, marking a 1.8% decrease (543,000 tons) compared to 2021. In general terms, the 2022 data appears to reflect a long-term declining trend.
The European Commission has adopted the European Biodiversity Strategy for 2030 (SEB 2030, COM(2020) 380 final), which sets the objective for Member States to protect at least 30% of their national territory and 30% of their seas, with at least one-third of these areas being strictly protected. These objectives are also incorporated into the National Biodiversity Strategy for 2030 (SNB 2030).
The indicator integrates spatial data from the main biodiversity protection systems existing in Italy (protected areas and the Natura 2000 Network), calculating the current protected surface both on land and at sea. It evaluates the variation from 1991 to 2023 and highlights the gap between the percentage of protected land and marine areas and the 30% target set by SEB 2030. The data used to calculate the extent of the protected area come from CDDA and the Natura 2000 database. Other Effective Area-based Conservation Measures (OECM) are not included, as the types of areas that may fall within this category have not yet been defined.
As of today, the total national coverage of protected areas, after accounting for overlaps between protected areas and Natura 2000 sites, is approximately 4,068,476 hectares at sea, equivalent to 11.62% of Italian territorial waters and the Ecological Protection Zone (ZPE), and about 6,532,341 hectares on land, covering 21.68% of the national territory. The extent of overlapping areas, i.e., those falling within both a protected area and a Natura 2000 site, has increased over time, reaching 862,631 hectares at sea and 2,447,046 hectares on land in 2023. The trends indicate that the percentage of protected national surface has stabilized since 2006 for marine areas and since 2011 for land areas. To meet the 30% target set by SEB 2030, an additional 18% of marine areas (approximately 6,600,000 hectares) and 8% of land areas (approximately 2,500,000 hectares) still need to be protected.
The Italian fauna is estimated to include over 58,000 species, with the total number reaching approximately 60,000 taxa when considering subspecies. However, this biodiversity is under threat, as indicated by IUCN assessments and population trends. Among the 672 species of Italian vertebrates (576 terrestrial and 96 marine), 6 are extinct in Italy, and 161 are threatened with extinction (accounting for 28% of the assessed species). Different vertebrate groups show varying percentages of risk: 2% for marine bony fish, 19% for reptiles, 21% for cartilaginous fish, 23% for mammals, 36% for amphibians, and up to 48% for freshwater bony fish (considering the CR+EN+VU IUCN categories). Additionally, terrestrial and marine vertebrate populations are generally declining by 27% and 22%, respectively.
Breeding birds are the only group for which two IUCN assessments have been conducted, seven years apart. Of the 278 species assessed in the latest 2019 evaluation, 5 are extinct, and 67 are threatened (compared to 76 in 2013), representing 26% of the evaluated species. Half of Italy's breeding bird species are not at immediate risk of extinction.
Among invertebrates, 9% of corals, 11% of dragonflies, 21% of saproxylic beetles, 6% of butterflies, and 11% of assessed bees are threatened with extinction. Invertebrates also show negative trends; for example, 16% of dragonfly populations are in decline, five times higher than those increasing.
The indicator describes land use (agricultural, urban, industrial or commercial, infrastructure, recreational, natural and semi-natural, water bodies, etc.), reporting the territorial surfaces associated with different classes according to the CORINE Land Cover classification system. Between 2012 and 2018, there was a continued general increase in artificial urban areas, primarily at the expense of agricultural land. In Italy, as in the rest of Europe, cultivated areas show a contraction, linked not only to urbanization processes but also to agricultural land abandonment.
The number of areas and the extent of protected marine surface have steadily increased over time. Currently, Italy has 39 Marine Protected Areas (MPAs), established in 10 Italian regions; of these, 29 are Marine Protected Areas (AMPs). Sicily and Sardinia are the regions with the highest number of marine protected areas, both in terms of quantity and protected marine surface.
Between 2012 and 2019, the national surface area of MPAs increased by 1.9%, thanks to the establishment in 2018 of two Marine Protected Areas: Capo Testa - Punta Falcone in Sardinia and Capo Milazzo in Sicily.
In Italy, as of today, 843 terrestrial protected areas (including those with a marine component) have been established, covering a total protected surface of over 3 million hectares, which corresponds to approximately 10.5% of the national terrestrial area. Analyzing the historical series (1922-2019), it is possible to observe, especially from the mid-1970s onward, a positive trend in terms of both the number and surface area of terrestrial protected natural areas. However, since 2008-2009, there has been a certain stabilization in the growth trends.
