DESCRIPTION:For Veneto Region\, the year 2022 was affected by anomalies in 
 terms of average temperature and recorded rainfall\, compared to the clima
 tic average of the last thirty years. The occurrence of these climatic con
 ditions highlighted the inevitable negative effects for the environment\; 
 in particular\, water resources were affected by this combination of clima
 tic criticalities\, both in terms of rivers’ flow rate and underground w
 ater flows\, also due to the poor snow accumulations recorded in the Alps 
 during the winter period.\nCritical profiles in terms of surface runoff ha
 ve been highlighted on various rivers and streams\, particularly in the su
 mmer period. The main Italian river\, the Po\, was also affected by a wate
 r flow decrease in 2022\, making evident the increase in the surfaces char
 acterized by the presence of sand islands\, visible along the river path.\
 nThis work\, carried out by the Territorial Planning Department of the Ven
 eto Region\, aimed at a quantitative analysis of the surface covered by sa
 nd islands and surface water in a sufficiently representative area of the 
 Po basin.\nFor the purposes of this study\, the area included between the 
 municipalities of Occhiobello (RO) and Ferrara was analysed (border area b
 etween Veneto and Emilia Romagna regions\, where Po river flows). The anal
 ysis was carried out for the month of July 2022\, comparing the data obtai
 ned with those relating to previous years (2020 and 2021).\nIn order to id
 entify the islands of sand\, multispectral Sentinel-2 satellite images wer
 e analysed\, taking into consideration the wavelengths of the visible (B02
 \, B03 and B04 bands)\, and that of the near infrared (B08 band). The area
  was then classified using supervised classification with the Random Fores
 t classification algorithm\, a methodology that allows to obtain high-prec
 ision classifications.\nConsidering the pixels’ size and the limits of t
 he supervised classification\, the precision of the analysis performed an 
 accuracy higher than 95%. The analysis remarks relevance for monitoring th
 e negative effects caused by the drought on the Po river. In the area unde
 r examination\, a constant decrease in the surface of surface water was ob
 served\, and a corresponding increase of natural sand islands. From the an
 alysis obtained\, thanks to the use of the classifier\, it is evident that
  the year 2022 was a year in which drought contributed to worsen the water
  stress for the Po river\, with evident consequences on the environment in
  terms of availability of the water resource and the rise of the salt wedg
 e near the river mouth. Moreover\, the study presented here confirms the i
 mportance of using satellite data and classification tools for monitoring 
 water bodies.

DESCRIPTION:NEREUS (Network of European Regions Using Space Technologies) i
 s a European association representing the interests of European regions th
 at use space technologies whilst simultaneously highlighting the regional 
 dimension of European space policy and programmes. It is the key mission o
 f NEREUS\, as a unique thematic network for matters of regional Space Uses
 \, to explore the benefits of space technologies for European Regions and 
 their citizens as well as to promote the use of space and its applications
 .\nVeneto Region is a NEREUS active member since 2008\, having played an a
 ctive role in promoting space technologies (GNSS and earth-observation) du
 ring the years.\nAs one of the historical members of NEREUS\, Veneto Regio
 n suggested some actions to boost activities on Earth Observation. Followi
 ng the inspiring principle “Bringing the benefits of space uses to Europ
 ean regions and their citizens”\, the proposal was to launch in 2023 the
  Working Group on Earth observation\, composed by of regional experts and 
 space technologies. The main ojectives are: 1) spreading the knowledge of 
 earth observation data and space technologies\; 2) sharing experiences tha
 t can lead to the creation of mutual synergies for a better data-governanc
 e\; 3) supporting local institutions\, citizens and companies in the use o
 f space technologies\; 4) inspiring and easing positive policy responses t
 o local institutions. \nIn this framework\, Veneto Region recently finaliz
 ed the application for the Interreg Europe project “SAT.SDI.F.A.CT.ION (
 SATellite data and Spatial Data InFrAstruCTures for an evidence-based regI
 ONal governance). In the same project\, NEREUS is the Advisory partner.\nE
 uropean Earth Observation System Copernicus contributes as a vital source 
 of knowledge to improve territorial and environmental management\, efficie
 nt use of natural resources and delivery of effective public policies and 
 services to citizens. However\, it is still not clear to which extent sate
 llite data are used by local and regional administrations\, specifically h
 ow much satellite data are integrated within regional Spatial Data Infrast
 ructure (SDI). Spatial Data Infrastructures\, as defined by the INSPIRE di
 rective\, are to be considered as a framework of policies\, institutional 
 arrangements\, technologies\, data\, and people that enable the sharing an
 d effective usage of geographic information by standardizing formats and p
 rotocols for access and interoperability. The overall scope of the project
  is to promote the exchange and transfer of experiences related to the use
  of Satellite Data in local and regional Spatial Data Infrastructures (SDI
 )\, leading to a better\, evidence-based governance of the regional territ
 ory.\nThe integration of Satellite Data in local and regional SDIs (Spatia
 l Data Infrastructures) is of strategic importance and with great potentia
 l to support government and decision making at sub-national level\, provid
 ing unrivalled information in different fields of application. However\, t
 he uptake of existing satellite data and services is not being fully used\
 , and their integration in added-value services for regional and local gov
 ernments is far from optimal. The SATSDIFACTION project aims at working ex
 actly around this issue\, promoting the exchange and transfer of experienc
 es related to the use of Satellite Data in local and regional Spatial Data
  Infrastructures as a mean to improve the performance of regional policy i
 nstruments\, eventually leading to a better\, evidence-based governance of
  the regional territory.
