An integrated analysis of recent climate change (including atmosphere, sea and land), and social reaction and adaptation, was conducted in central Italy and the northern portion of the Adriatic Sea. The collected environmental data included meteorological, oceanographic, and river gauges stations, covering the time period 1961-2009. Social data included 800 questionnaires and interviews carried out on selected samples of residents, decision-makers, and emergency managers. The trend analysis of air temperature data detailed an overall increase in all seasons, whereas rainfall data showed decrease in winter, spring, and summer, and increase in autumn, influencing river flow changes. Marine data showed a warming of the water column after the year 1990, particularly relevant in the cold season. Surface salinity increased in spring and summer and strongly decreased in autumn and also in winter (due to the spreading over the basin of the increased autumnal river runoff). These changes, combined with anthropogenic effects, appear to influence the northern Adriatic marine environment and ecosystems. Impacts in the coastal areas are also evident inland; the analysis of Aridity index, and potential water deficit, suggests negative impacts in terms of soil deterioration and agricultural productivity, particularly in the area near the coastline. At the same time, the analysis of social data revealed awareness among local residents of these impacts and associated risks connected to climate change. Yet, this awareness is not currently translated into preventive and protective actions; among the main reasons for this delay is also ineffective information exchange among citizens, public administrators, and the scientific community.

Abstract
An integrated analysis of recent climate change (including atmosphere, sea and land), and social reaction and adaptation, was conducted in central Italy and the northern portion of the Adriatic Sea. The collected environmental data included meteorological, oceanographic, and river gauges stations, covering the time period 1961-2009. Social data included 800 questionnaires and interviews carried out on selected samples of residents, decision-makers, and emergency managers. The trend analysis of air temperature data detailed an overall increase in all seasons, whereas rainfall data showed decrease in winter, spring, and summer, and increase in autumn, influencing river flow changes. Marine data showed a warming of the water column after the year 1990, particularly relevant in the cold season. Surface salinity increased in spring and summer and strongly decreased in autumn and also in winter (due to the spreading over the basin of the increased autumnal river runoff). These changes, combined with anthropogenic effects, appear to influence the northern Adriatic marine environment and ecosystems. Impacts in the coastal areas are also evident inland; the analysis of Aridity index, and potential water deficit, suggests negative impacts in terms of soil deterioration and agricultural productivity, particularly in the area near the coastline. At the same time, the analysis of social data revealed awareness among local residents of these impacts and associated risks connected to climate change. Yet, this awareness is not currently translated into preventive and protective actions; among the main reasons for this delay is also ineffective information exchange among citizens, public administrators, and the scientific community.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
