Climtate Change Related Statistics and Indicators (CCRSI) § Meteo-climatic statistics and Indices can describe

Climtate Change Related Statistics and Indicators (CCRSI) § Meteo-climatic statistics and Indices can describe climate variability and changes. Long time series of data represents useful tools for policy makers designing efficient policy, supporting adaptation and disaster risk analysis and actions in cities governance § Standardized, complete and comparable information systems are needed to develop such complex analysis. Information from different sources and domains: urban systems, infrastructures, economy, demography, meteclimatic data § integration of statistical and geographical information is crucial to build a complete and updated knowledge framework at local scale § to provide common methodologies and internationally comparable CC Related Statistics and Indicators (CCRSI) referenced statistical frameworks have been developed by international Organizations § NSOs are called to enhance their role to provide high quality statistics reliable, consistent, timely, comparable, accessible D.

NSOs role to provide CCRSI § official statistics already available but produced with different

NSOs role to provide CCRSI § official statistics already available but produced with different purposes make existing statistics useful for CC analysis and produce ‘new statistics’ § data provided by different producers coordination, standardization, cooperation at national and international level among agencies, public institutions, research centers § new data to be provided meet users information needs cooperation, coordination reliable statistics Key concepts standardization of terminology, classifications, methodologies integrated multidimensional interdisciplinary approach methodologically sound several data providers several sources international comparable indicators D.

Conclusions and further work developments § variability and extreme weather and climate events seem

Conclusions and further work developments § variability and extreme weather and climate events seem have increasingly affected Italian cities in the last fifteen years, with damages to human health, infrastructures, services delivery, cultural heritage § statistics and indicators, provided for Italian Regional Municipalities, point out relevant variations in minimum and maximum temperatures trend and precipitation patterns § the role of many local public institutions, become increasingly aware of CC impacts on urban systems, is crucial to face CC impacts § the design of efficient CC adaptation and mitigation strategies need inter-disciplinary approaches, to based on involvement and cooperation of different Institutions, agencies and research centers § statistics “more fitness for use” support multidimensional analysis to describe interactions among social, economic and environmental phenomena § meteoclimatic statistics provided by Istat strengthen information available at local and temporal scale to support capacity building in the area of adaptation policy and CC action responses § further developments of Istat work: ü statistics and indicators calculated for Italian provincial municipalities ü integration of statistics of different domains to provide new analyses ü regular update of database through annual survey editions ü strengthening cooperation of Istat with other meteoclimatic data producers D.
