Gli effetti antropici e climatici sulla disponibilità delle acque sotterranee della Piana ionico-lucana
No full textThe paper deals with the groundwater availability along the lonian coastal plain (Southern Italy), between the mouths of Sinni and Bradano Rivers. Subjected to intense agricultural and tourism activities, the availability of the tapped groundwater is seriously important for the economic growth ofthis coastal area, especially due to the increasing frequency of droughts. The stratigraphical and hydrogeological set-up of the area as the geochemical features of the groundwater arise from the data analysis of 1130 boreholes, widespread over the whole area and from 1.3 up to 423 meters deep. The aquifers of the area could be distinguished in two types. The former encloses aquifers constituted by marine terraced deposits and alluvial river valleys deposits. The latter includes that one of the coastal plain deposits. It is the most interesting for practical utilisation and it is considered in the paper.
The analysis of long time series is based on piezometric data (1927 to 1984), monitored by 60 wells, temperature, rainfall and river discharge data. The piezometric regimen and the maximum piezometric variation are characterised. The trend analysis, the autocorrelation and the crosscorrelation were applied to all variables. As a result, the modification of groundwater availability was characterised considering the spatial variation of the hydrogeological conditions. The relationships existing between rainfall, temperature, river discharge variations and piezometric surface height.UnpublishedChietiope

Apulian piezometric time series: regime and climatic and human effects
No full textThis work is based on data acquisition and analysis of chronology sequences of piezometric, rainfall and thermometric data of Apulian aquifers. Methods of time series analysis are used. This approach has allowed characterising the piezometric regime and trend related to the natural recharge variation.Published153-162N/A or not JCRope

La siccità e la disponibilità di acque sotterranee in Puglia
No full textMediante l'utilizzo di metodi di statistica delle serie storiche è stato possibile evidenziare alcuni caratteri degli acquiferi pugliesi, quali il regime piezometrico, i rapporti intercorrenti tra precipitazioni meteoriche, temperatura atmosferica e variazioni piezometriche.
La ricostruzione degli aspetti tendenziali, negli ultimi 30 anni, delle variazioni piezometriche ha mostrato un abbassamento considerevole della quota piezometrica in tutte le unità idrogeologiche, con valori più accentuati per le aree interne della Murgia e del Tavoliere.
Gli elementi raccolti segnalano un progressivo depauperamento delle falde idriche proprio dove si concentrano le acque sotterranee di migliore qualità. Si rende necessaria, quindi, una politica gestionale delle risorse idrica sotterranee che consenta agli acquiferi di accumulare acque sotterranee nei periodi umidi, in cui abbondano le acque di superficie, per restituirle nei periodi aridi, svolgendo una funzione di compenso pluriennale.Published187-1936A.

Effetti antropici e naturali sul degrado quantitativo delle acque sotterranee del Tavoliere
No full textThis work is based on data acquisition and analysis of chronology sequences of piezometric, rainfall, thermometric and runoff data of Apulian Tableland aquifer. Methods of time series analysis are used. This approach has allowed characterising the piezometric regime and trend related to the natural recharge variation. The historical character of measurement period, last sixty years, is very important to evaluate the human effect.Published143-152N/A or not JCRope

The role of climate in promoting landslides in the seismic area of the Appennines, Southern Italy
No full textThe study area is located in Southern Italy, southeast of Naples (Figure 1). The phenomena of slope instability and floods have long been a constant feature in this portion of the Apennines, with earthquakes and meteoric events accounting for the main triggering factors. Landslides have often resulted in dreadful economic and human losses. A magnitude-6.8 earthquake that triggered many large landslides hit the study area on November 23, 1980.
A number of geological, geomorphological, hydrological and geotechnical features of the study area are examined in detail in the final technical report of an EEC research project (EEC 1996).
This paper examines the space distribution of rainfall and temperature accounting for the distribution of landslides before the earthquake on 23 November 1980 and the changes occurred afterwards. The major climatic elements, namely monthly precipitation and temperature, are analysed with geostatistic methods and discussed. The space variability is compared to the landslide proneness distribution within the area.PublishedExeter (UK)6A. Monitoraggio ambientale, sicurezza e territorioope
Balancing Objectivity and Subjectivity in Agricultural Funding: The Case of AKIS Measures
No full textThe agri-food system is faced with numerous challenges of sustainability, calling for the improved evaluation of rural development projects. However, a gap exists in the comprehension of the application of both objective and subjective indicators in project selection criteria among regions. This study aims to bridge this gap by exploring, in detail, the nature and utilization of objective and subjective indicators in the Agricultural Knowledge and Innovation System (AKIS) environment in Italy. The approach entails the analysis of documents, with a focus on data relating to the AKIS initiative across regions. The comparative approach is also used to establish the priority that regions assign to indicators. The results include the use of both objective indicators, such as the number of sectors covered, and subjective ones, such as innovation and responsiveness to local needs. Besides, the comparative approach emphasizes the complexity of the AKIS initiative, with some domains tending toward objective indicators, while others tend toward subjective indicators. The study contributes to the development of a composite framework for evaluating rural development projects and emphasizes the need for further research to develop evaluation methodologies further, so that future frameworks will be standardized as well as sensitive to regional heterogeneity
