1 User Awareness & Training: Use of Copernicus data for land monitoring and environmental reporting in Italy Lisbon, Portugal 14 th February 2014 ISPRA

2 Contents Introduction to land take, urban sprawl and ISPRA activity QGIS, open source GIS software Live Demonstration Use of Products Calculation of land use statistics and urban sprawl indicator at the local level using Urban Atlas Calculation of landscape metrics at the municipal level using the Degree of Imperviousness Summary & Questions

3 Introduction Land take: occupied surface converted from natural or agricultural use to built-up Urban sprawl: unplanned, low-density urban expansion, characterized by a mix of land uses on the urban fringe Land take, soil sealing and urban sprawl are phenomena that are posing serious challenges to urban planners.

4 Report on Urban Environmental Quality The results of land monitoring are published in reports: Report on urban environmental quality Improve people s awareness of land take Foster environmental policies

5 Italian 2012 State of Environment report by National and Regional/Provincial Environmental Protection Agencies Indicators derived from Copernicus services (soil sealing at municipal level and soil sealing in coastal areas) State of Environment Report

6 Land Monitoring and Environmental Reporting Copernicus Land Monitoring Services Harmonization Integration Environmental Reporting Geoportals Local and In Situ Data Elaboration of Indicators Soil Sealing Land Take Web Sites Policy Makers Public Stakeholders

7 Land Monitoring and Environmental Reporting Indicators: Consistency over time and space (MMU, scale, accuracy and underlying classification) Ability to capture trends and changes in land take and soil sealing as soon as they appear Ability to provide a coherent description of the phenomenon at the national level Ability to be consistent in fragmented areas where the distinction of sealed and natural soils needs a higher level of detail Indicators about soil imperviousness can provide information about temporal and spatial trends to a public authorities and policy maker.

8 QGIS: Geographic Information System QGIS: View and process vector (e.g. Urban Atlas) and raster (e.g. Degree of imperviousness) data Free and open source Actively developed QGIS works in several operating systems: Windows, Linux, Mac, Android

9 QGIS download and installation Download the installer from org/osgeo4w/osgeo4wsetup-x86.exe

10 QGIS plugin: LecoS Free QGIS plugin for the calculation of landscape metrics Installation of the plugin in QGIS Martin Jung (2012) LecoS - A QGIS plugin to conduct landscape ecology statistics,

11 First case Calculation of land use statistics and urban sprawl indicator at the municipal level using Urban Atlas

12 Urban Atlas: land use at the local level Download Urban Atlas data from

13 Urban Atlas: land use at the local level Use of Urban Atlas for the calculation of class statistics and urban sprawl indicator Objective: assess land use and urban sprawl at the local level Study area: Trieste province (area 212 km 2 )

Urban green areas, sports and land without current use 5. Agricultural, semi-natural areas and wetlands 6. Forests 7.

14 Visualization of the Urban Atlas layer Reclassification of the Urban Atlas classes in 7 classes: 1. Continuous fabric residential areas 2. Discontinuous fabric residential areas 3. Industrial, commercial and infrastructure areas 4. Urban green areas, sports and land without current use 5. Agricultural, semi-natural areas and wetlands 6. Forests 7. Water bodies Calculate Area Statistics Calculate the Urban sprawl indicator: the ratio between the sum of the discontinuous urbanized surface and the total urbanized surface Urban Atlas: land use at the local level

15 Second case Calculation of landscape metrics at the municipal level using the Degree of Imperviousness

the average size of the polygons the edge density, which is the ratio between the sum of the built-up

16 4 landscape metrics calculated using the Degree of Imperviousness: the percentage of the built-up area in the municipality the percentage of the built-up area of the largest polygon over the total built-up area the average size of the polygons the edge density, which is the ratio between the sum of the built-up area perimeter and the municipal surface [m/ha] Study area: Milan Degree of Imperviousness: landscape metrics
