Qualche anno fa analizzai i dati del progetto CORINE Land Cover relativi alla Campania, focalizzandomi sui tre censimenti tra il 2000 ed il 2012. Oggi invece estenderò quell’analisi inserendo sia i dati del 1990 che gli ultimi disponibili attualmente, cioè quelli del 2018.

L’analisi questa volta la farò usando Python e la estenderò al resto dell’Italia verso la fine.

Prima di iniziare

Librerie

Per raggiungere l’obiettivo userò le librerie che seguono:

Codice

import pathlib
import geopandas as gpd
import pandas as pd
from functools import reduce
import matplotlib.pyplot as plt
from matplotlib.gridspec import GridSpec

import warnings
warnings.filterwarnings('ignore')
warnings.simplefilter('ignore')

Fonti dati

Ho rielaborato i dati CORINE Land Cover dal 1990 al 2018 inserendoli in un unico GeoPackage che è possibile scaricare da qui. I dati sono stati processati preventivamente usando PostGIS in modo da associare ai poligoni della CLC anche quelli dei Comuni italiani al 2022 dell’ISTAT. E’ stato indispensabile questo passaggio preventivo perchè ho dovuto correggere gli errori topologici sui dati ISTAT e, al momento, trovo molto più comodo correggere gli errori topologici tramite SQL piuttosto che con Python.

Codice

main_folder = pathlib.Path('/home/max/Desktop/clc')
dataset = main_folder.joinpath('clcitalia.gpkg')

1. Lettura e normalizzazione dei dati

In questa fase ho proceduto ad estrarre un po’ di dati statistici che userò nei passaggi successivi. Sono perlopiu analisi mirate al calcolo delle superfici che ho espresso in ettari. Fatte queste analisi mi sono liberato dei dati geometrici perchè, non dovendoli più usare, mi alleggeriscono le analisi successive in termini di prestazioni hardware.

Le colonne label* fanno riferimento alla nomenclatura delle tre classi della mappa CORINE Land Cover per ogni singolo anno. Per interpretare la nomenclatura vai qui. Come puoi vedere sono presenti le colonne relative al Comune, Provincia e Regione di apparteneza, l’estensione dell’area comunale(sup_com_ha) e quelle relative alle superfici della CLC che mi sono calcolato in precedenza.

2. Focus sulla Campania

Per appartenza territoriale partirò proprio dalla Campania, lo faccio anche per riprendere parte della analisi del mio vecchio articolo.

E’ visibile abbastanza chiaramente un netto aumento delle superfici artificiali con un conseguente arretramento di quelle forestate e di quelle agricole. Le aree forestate tra il 1990 ed il 2018 hanno subito un arretramento quasi doppio rispetto a quelle agricole e le superfici artificiali sono quelle che hanno maggiormente “beneficiato” di questo arretramento complessivo delle due classi di CLC. Si potrebbe dire che l’urbanizzato ha eroso foreste ed aree agricole in quasi 30 anni.

Scendendo di un livello, quindi andando ad approfondire di più il dato passando al secondo livello CLC, possiamo verificare i trend negativi a quali specifiche superfici fanno riferimento.

Le aree arbustive e con alberi radi hanno avuto la peggio, a seguire i terreni arabili, pascoli e foreste. Netto è invece l’aumento delle aree aperte, classe in cui nel terzo livello CLC ci sono le aree percorse dal fuoco(da tenere in mente per richiami successivi!). Seguono, nell’incremento, le aree urbanizzate, le aree per colture eterogenee e quelle per lo sviluppo di siti industriali e commerciali.

Passando al livello tre della CLC, ho voluto graficare la sola differenza tra 1990 e 2018 per motivi di leggibilità del grafico. In termini di aumento di copertura del suolo c’è l’avanzamento, quasi identico, delle piccole aree destinate a colture annuali e delle aree con vegetazione frammentata. A seguire ci sono le aree urbane discontinue e quelle occupate da orti, vigneti e alberi da frutto.

Una riflessione che mi sento di fare è che l’avanzamento del tessuto urbano discontinuo ha frazionato il territorio agricolo, generando aree a piccole colture agricole.

Significativo anche l’aumento di estensione delle aree percorse dal fuoco.

I decrementi sono la cartina di tornasole degli incrementi che ho descritto poco fa e che potrebbero confermare la mia riflessione sul frazionamento del territorio naturale ed agricolo, portato avanti dall’avanzamento delle classi legati ai suoli artificiali.

2.3 Focus sui Comuni

L’analisi che segue tenta di rispondere alla domanda: “quali sono i Comuni campani in cui i fenomeni esposti poco fa hanno avuto un maggior impatto?”

Mi concentrerò sul terzo livello della CLC, in particolare sulle aree artificiali, aree agricole e foreste ma anche sulle discariche, le aree percorse dal fuoco ed il verde urbano.

Visto che dal 2000 in poi l’accuratezza geometrica del dato CLC è aumentata considerevolmente, le analisi di dettaglio che seguono si concentreranno sulla differenza tra 2000 e 2018.

Onestamente non so come interpretare l’arretramento delle aree artificiali, andrebbe fatta una ulteriore analisi per valutare se sono Comuni che si sono spopolati in quasi trenta anni.

L’aumento è abbastanza facile da indagare per me che sono del posto. Napoli ha una popolazione di quasi un milione di abitanti che triplica nei giorni feriali, per non parlare poi dei turisti. E’ un’area molto congestionata con possibilità di nuova edilizia prossime allo zero; risulta normale quindi che Comuni più prossimi al Capoluogo di Regione stiano accogliendo “l’esubero” di popolazione. Faccio riferimento a Castello di Cisterna, Volla e Quarto.

Il caso di Atrani è particolare perchè è il Comune più piccolo d’Italia ed è posto in una zona abbastanza impervia della costiera amalfitana; è probabile che nel 2000 non si sia data molta importanza all’area.

E’ significativo per me che nella top 10 del decremento di aree forestate ci siano Terzigno, Ercolano e Trecase. Lo è perchè sono tra i Comuni ricadenti nell’area del Parco Nazionale del Vesuvio che hanno subito danni al patrimonio boschivo a causa dell’incendio che ci fu nel 2017.

Le aree in cui i boschi avanzano sono perlopiu aree rurali, a vocazione agricola, che pian piano si stanno spopolando.

Tra i Comuni con maggior aumento della aree articifiali abbiamo visto che c’è Volla che è tra i Comuni con maggior decremento delle aree agricole. Poco sopra ho fatto una riflessione sul perchè della redistribuzione del livello 1 della CLC. Due indizi non fanno una prova, ma tre?

3.2 Grafici

Mi limiterò a commentare solo la analisi a scala nazionale perchè quelle a scala comunale hanno risultati che, sebbene intuibili dal punto di vista delle variazioni, hanno una valenza territoriale molto forte(come lo è stato per la Campania) e non conoscendo tutti quei territori preferisco lasciare a chi è del posto le considerazioni del caso.

Conclusione

Sembra abbastanza chiaro che in Italia negli ultimi trenta anni circa si sia preferito sacrificare il paesaggio agricolo e forestale in favore di quello urbano. Si parla molto di Urban Heat Island e della riduzione di questi fenomeni tipici delle aree urbane. Magari, se si fosse riammodernato il costruito negli ultimi trenta anni al posto di edificare in nuovi luoghi, il fenomeno delle isole urbane di calore ci avrebbe colpito in maniera molto minore di quanto non ci colpisca adesso(e nei prossimi anni!). Avremmo così preservato il nostro patrimonio boschivo ed agricolo rendendo il Bel Paese ancora più bello.
