Drought Situation

In Italian Only

Bollettino Gennaio 2025

Secondo i dati Copernicus, a livello globale questo è stato il Gennaio più caldo registrato dal 1979, rispetto al periodo di riferimento 1991-2020. A livello europeo, questo mese si attesta al secondo posto, dopo Gennaio 2020 (vedi grafico). Le temperature superficiali del Mediterraneo si sono mantenute al di sopra della media, così come in buona parte dell’Atlantico centrale e nord-orientale. Le piogge sono state inferiori alla media su buona parte dell’Europa centro-occidentale, Gran Bretagna centro-meridionale, Scandinavia e Italia settentrionale e meridionale. Sul lungo periodo (12 mesi) la siccità severo-estrema interessa i Paesi centro-orientali con una percentuale che aumenta spostandosi verso est (vedi mappa interattiva).
  • Gli invasi di Sardegna, Sicilia e Puglia (Capitanata) contengono da 3% al 15% di acqua in meno rispetto all’omologo periodo del 2023, mentre la Basilicata presenta un lieve incremento dell’1% (vedi grafico).
  • In merito ai grandi laghi del nord Italia, al 10 Febbraio 2025, presentano tutti valori di riempimento ben al di sopra della media grazie soprattutto agli apporti pluviometrici fra fine Gennaio e inizio Febbraio.
  • La produzione di energia idroelettrica in Sicilia nella settimana fra il 27 Gennaio e il 2 Febbraio chiude in netta risalita rispetto allo scorso anno e anche ad altri anni quali il 2023, 2021 e 2018.
Previsioni per i prossimi mesi
Per quanto riguarda le temperature dell’aria del trimestre Marzo-Maggio 2025, i dati d’insieme dei maggiori centri europei per le previsioni a medio termine indicano valori sopra la media su tutta Europa con una probabilità dal 60 al 100%. Anche le temperature superficiali del Mar Mediterraneo dovrebbero restare al di sopra della media per tutto il trimestre con una probabilità del 70-100%. Per quanto riguarda le piogge, la previsione indica valori superiori alla media su parte della Scandinavia. Sul resto del continente i valori dovrebbero mantenersi in media o, con una probabilità fra 40% e 50%, al di sotto.

Drought WebGIS

A WebGIS application based on open source solutions customized to integrate different datasets and share maps and graphs of drought indices with researchers, decision-makers and other stakeholders. Different functions allow to select sections of territory or visualize the trend of the indices in a specific pixel. Maps and graphs can also be downloaded in png format.
Go to Drought WebGis

Please Note: Due to the size of the images, it is possible to download sections of the vegetation indices smaller than the whole geographic window.

Please Note: due to problems concerning the Terra MODIS satellite, the TCI and VHI indices are available until the 9th of November 2022. They will be replaced soon with new products.

Other Services

Open data

Through CKAN and GeoServer, a complete catalog to publish data and metadata in several formats and standard protocols. Spatial data can be integrated and reused by any third-party client applications.

Opendata catalogue

API REstful

The service allows the integration of any client application data from the Drought Observatory Spatial Data Infrastructure. The RESTful APIs developed are available on the GitHub platform.​

The drought is a complex phenomenon

The complexity of the drought phenomenon requires the availability of a system as comprehensive and integrated as possible to respond to the different users requests.

The challenge
Increasing environmental resilience

Heat waves and droughts have important and increasing repercussions on physical, chemical and biological systems, and on some socio-economical aspects such as health, agriculture, natural ecosystems and tourism. One of the main challenge to cope with drought is to reduce the temporal gap between the onset and development of a dry period, and the response in managing drought-related emergencies.

A Scientific Proactive approach
Technical support and timely information

Although these extreme events require effective actions, policymakers and water users often show low preparedness because of the lack of a proactive approach consisting of monitoring and forecasting activities, mitigation measures and public education.

A frequent Phenomenon

After flooding, it is the second natural disaster that affects the population.

Long term impact

The impact on the environment and human activities can show up late and persist even after the end of the drought event.

HIGH VARIABILITY

Its intensity and spatial extent are extremely variable.

A CREEPING PHENOMENON

With respect to other natural extreme events, drought is characterised by a slow and often difficult to define onset and a long-lasting evolution.

Drought Observatory: the reason why

Drought monitoring supports a better resilience to reduce the impacts of drought events

Drought monitoring and forecasting system

Institute of BioEconomy of the National Research Council (IBE-CNR) created a system to provide a semi-automatic, detailed, timely and comprehensive operational service. This service, initially developed for Tuscany Region, supports decision makers, water authorities, researchers and general stakeholders.
More about the SYSTEM

Integration of ground-based and satellite data

Meteorological stations network, satellite images and models are integrated through an open source and interoperable SDI (Spatial Data Infrastructure) based on PostgreSQL/PostGIS to produce vegetation and precipitation indices to follow the occurrence and evolution of a drought event.
More on SDI

The Indices: Drought occurrences and trends

The system is based on a monitoring component and on a forecasting ones. It uses two type of indices:

  • direct climate-based indices.
  • indirect vegetation-based indices
More about the indices

A continuous Work-in-Progress

Spatial Data Infrastructure

New technical improvements in the ICT infrastructure, coupled with scientific advances, allow a timely, ready-to-use and users-specific upgrading of the early warning communication.

SOA | OGC | PostgreSQL

A Service-Oriented Architecture (SOA) based on Open Geospatial Consortium (OGC) standards. Database-centred architecture, with PostgreSQL DataBase Management System.

Innovative Approach

The geographic data flows (from the download of remote sensing and climatic data to the storage of final indices) and all the related geoprocessing functions are integrated in a single environment.

Advanced Statistical Procedures

The integration of the PL/R (R Procedural Language) wrapper into the procedural language of PostgreSQL (PL/pgSQL) allowed the creation of advanced statistical procedures using R engine.
