Situazione siccità Agosto 2019

Dal punto di vista delle precipitazioni Agosto è risultato meno piovoso della norma. Le precipitazioni, a carattere temporalesco, si sono concentrate soprattutto nella terza decade del mese ed hanno interessato le zone interne orientali ed appenniniche settentrionali. Anche il numero

WEB GIS

WEB GIS DROUGHT

A WebGIS application based on open source solutions customized to integrate different datasets and share maps of drought indices with researchers, decision makers and other stakeholders.

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.

API

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

Take the survey on drought

This survey (in Italian) will help us to know better information needs of the users and to improve our services.

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 proactive Approach

Scientifically-based technical support to deliver simple, timely and reliable 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

Drought is the second natural disaster (after flooding) that affects population.

A creeping phenomenon

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

High Variability

Its intensity and spatial extent are extremely variable.

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.

Why a drought observatory

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

Drought monitoring and forecasting system

Institute of Biometeorology of the National Research Council (IBIMET-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.

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.

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.

The SDI set up for the Observatory allows the dissemination of comprehensive, up-to-date information, customisable for different end users and delivered through different channels.

all SERVICES AND TOOLS

Open Data

A complete catalogue (CKAN and GeoServer) with data and metadata in different formats and standard protocols. Any third-party client applications can easily reuse the spatial data.

web gis

A customised Open Source WebGIS application to integrate different datasets and share maps of drought indices with researchers, decision makers and other stakeholders.

Monthly Updates

Monthly updates on Tuscan drought current and future conditions and local impacts, press releases and useful links. [The bulletin is issued only in Italian.]

RESTful APIs

RESTFUL APIs for data downloading, clipping and geoprocessing ensure the interoperability.

User Survey

The users’ survey collecting suggestions and needs on drought management and information, so to improve effectiveness of the drought operational services.​

Glossary

A selected list of drought related keywords. Sources: EarthLabs, Intergovernmental Panel on Climate Change (IPCC), National Drought Mitigation Center (NDMC).​

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.

THE SPATIAL DATA INFRASTRUCTURE​

A Continuous Work-in-Progress.

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.

Reducing the climate change impacts and increasing environmental resilience for agriculture, human well-being, and natural resources conservation.
