Water transfer from Basilicata to Puglia: a technical, economic and institutional challenge
2007
The necessity of supplying Puglia by transfer of water resources from Basilicata (250 Mm/year mainly for civil use but also for agricultural and industrial uses) and another bordering region (Campania for 200 Mm/year only for civil use) arises from the scarcity of water resources inside Puglia, where precipitation is very low (400 mm/year), rivers are few and with limited watersheds and costal aquifers are overexploited with salt intrusion. Moreover recent droughts have pointed out the need for revising water supply policy in Puglia, looking for the increment of the transfer of water resources from Basilicata (50 Mm/year) and Campania (32 Mm/year) and the development of feasibility studies …
The Management of Water Resources during Drought in Southern Italy
1999
The aim of this paper is to describe how one of the most severe droughts of the century in Sicily has brought awareness of the insufficiency of the water resources system supplying Palermo, due not only to the lack of timely infrastructural measures, but also of an appropriate decisional framework. The experienced shortage has directed research efforts to overcome this problem. As a matter of fact, the 1989–90 drought gave clear evidence of how an heavy hydrologic failure can result in a real crisis depending on the system which suffers from it. Unplanned urban expansion and increased demands levels, mixed with the lack of a drought-oriented water managenment, have produced considerable dis…
The Intervention of Hydrogeophysics in the Economics of Groundwater Exploitation and Management in Sicily
1989
Abstract The problem of the preservation of water resources in Sicily presents various aspects, some of which have been treated by a number of works. Among the different applied methodologies, the geophysical ones occupy an important place. Their contribution, directed to an economic and efficient exploitation and management of groundwaters, can be useful for selected “risk” areas as well as for more regional programmes. In fact, uncontrolled drillings on relatively rich aquifers occur in several zones of this island; the economically disadvantageous exploitation causes also heavy impoverishment and pollution phenomena. The fragmentation of charges and the lack of a planning Regional Body m…
Final Considerations and Open Scenarios
2016
European river contract experiences demonstrate a growing integration between these contractual agreements and the other instruments of water resources management, and urban and territorial planning. Therefore, river contracts represent innovative places for a new governance of river ecosystems and territories, also in compliance with subsidiarity principle. The twofold nature of these contractual agreements—technical dimension and concertative approach—together with their expected wide evolution, allow to identify river contracts not only as sectoral tools for water resource protection and management, but also as catalysts of a new culture of water, recalling the deep interrelationships ex…
On Sustainable Management in Local Governance of Water: a Prospective Localized Study
2006
In the face of the changes in the planet's natural resources and of their unequal distribution, it is becoming more urgent that contemporary societies oversee environmental assets in a global manner. Although international directives, when they are transposed into national laws, may set specific objectives, meeting them at the local level is as yet an uneven enterprise. Nevertheless we hope to demonstrate, using a case-study involving local tensions over water resources, that public management of the crisis may be developed that effectively involves the civic society, by using the incentives and enforcement tools of central government and of local institutions.
Roadmapping the Transition to Water Resource Recovery Facilities: The Two Demonstration Case Studies of Corleone and Marineo (Italy)
2022
The current exploitation of freshwater, as well as the significant increase in sewage sludge production from wastewater treatment plants (WWTPs), represent nowadays a critical issue for the implementation of sustainable development consistent with the circular economy concept. There is an urgent need to rethink the concept of WWTPs from the conventional approach consisting in pollutant removal plants to water resource recovery facilities (WRRFs). The aim of this paper is to provide an overview of the demonstration case studies at the Marineo and Corleone WRRFs in Sicily (IT), with the final aim showing the effectiveness of the resources recovery systems, as well as the importance of plant o…
A Decision Support Tool for Water and Energy Savingin the Integrated Water System
2015
Abstract In the last decades, a growing attention on energy saving associated with water resources usage and leakages reduction has been recorded at both national and international level. Scientific research has focused on implementation of several methodologies aimed at the understanding of energy transformation processes occurring in the integrated water system. The main concern is then identifying energy impacts associated to each macro-area of integrated water system, such as collection, treatment and distribution, and analysing the potential interactions between them. Unfortunately, only overall energy consumptions are usually available at national level. The main objective of the pape…
Mediterranean Climate and Eutrophication of Reservoirs: Limnological Skills to Improve Management
2011
Sicily is the largest Mediterranean island and one of the most densely populated areas in the region. To counteract the periodic oscillation in water availability and fulfill drinking and agriculture needs, about 30 dam-reservoirs, impounding in total 750 106 m3, were built in the last 60 years. However, the inherent features of the Mediterranean climate and the total lack of awareness from local authorities have contributed to a progressive increase in the trophic state of these human-made lakes. In particular, the water is stored during the winter rainy season and then it is intensively used in the dry summer. These operational procedures, in particular the time separation between filling…
Emerging topics in scientific research on global water-use efficiency
2019
AbstractA bibliometric analysis of research articles published on water-use efficiency was performed using the Web of Science database and evaluated. Journal titles, publication years, subject categories, keywords and countries publishing were obtained. A number of 2077 papers were retrieved, two-thirds of them published in the last decade. The articles were published in 439 journals, with Agricultural Water Management, Agronomy Journal, Crop Science, Field Crops Research and Indian Journal of Agricultural Sciences the most productive. Most of the leading productive journals have Impact Factors in the top quartiles of the Journal Citation Reports. Agronomy, Plant Sciences, Water Resources a…
Hydrological Analysis of Loess Plateau Highland Control Schemes in Dongzhi Plateau
2020
Gully Consolidation and Highland Protection (GCHP) Project is a major soil and water conservation and land remediation project implemented in the Chinese Loess Plateau (CLP). As the connection between the mechanisms of erosion and practical applications for addressing it is not clear, the implementation of engineering measures to combat the problem has been insufficient to date. This study used field investigation and descriptive statistics, together with hydrological analysis modeling to gain an understanding of the impact of the Loess Plateau Highland Control Schemes on the evolution of the Dongzhi Plateau as the largest, most well-preserved, and the thickest loess deposit region in China…
