Forest drainage: a threat to benthic biodiversity of boreal headwater streams?
1998
1. Forest drainage, including mainly ditching of waterlogged peatlands in order to increase wood growth, has caused substantial changes in the hydrology and water quality of Finnish streams. However, knowledge on the ecological impact of these changes is poor. This paper studies the potential impact of forest drainage, catchment characteristics and habitat factors on the water quality and benthic macroinvertebrates in headwater streams of the River Isojoki, western Finland. An intensive programme of water sampling was carried out at nine study sites, while zoobenthic samples covered a total of 18 streams. 2. According to multivariate regression models concentrations of aluminium and suspend…
In Itinere STRATEGIC ENVIRONMENTAL ASSESSMENT of an integrated provincial waste system
2009
In the paper, the practical problem of analysing in an integrated way the performance of provincial waste systems is approached, in the framework of the Strategic Environmental Assessment (SEA). In particular, the in itinere phase of SEA is analysed herein. After separating out a proper group of ambits, to which the waste system is supposed to determine relevant impacts, pertinent sets of single indicators are proposed. Through the adoption of such indicators the time trend of the system is investigated, and the suitability of each indicator is critically revised. The structure of the evaluation scheme, which is essentially based on the use of ambit issues and analytical indicators, calls …
On new means with interesting practical applications: Generalized power means
2021
Means of positive numbers appear in many applications and have been a traditional matter of study. In this work, we focus on defining a new mean of two positive values with some properties which are essential in applications, ranging from subdivision and multiresolution schemes to the numerical solution of conservation laws. In particular, three main properties are crucial—in essence, the ideas of these properties are roughly the following: to stay close to the minimum of the two values when the two arguments are far away from each other, to be quite similar to the arithmetic mean of the two values when they are similar and to satisfy a Lipchitz condition. We present new means with these pr…
La Valle dei Templi in epoca medioevale. Caratterizzazione antropologica e paleopatologica delle sepolture antistanti in Tempio della Concordia
2021
Riassunto ― Il lavoro presenta i risultati delle analisi bio-archeologiche effettuate su resti scheletrici umani rinvenuti in quattordici sepolture di epoca medioevale rinvenute nel Parco Archeologico della Valle dei Templi di Agrigento (Sicilia). L’obiettivo è stato l’acquisizione delle informazioni necessarie per la ricostruzione del profilo biologico di ciascun individuo, al fine di determinarne il sesso, la stima dell’età biologica alla morte, la stima della statura e la valutazione delle patologie e degli indicatori di stress occupazionale mediante le correnti metodologie e tecniche diagnostiche di tipo antropologico. Sebbene il cattivo stato di conservazione di alcuni individui non ne…
A new definition of soil to promote soil awareness, sustainability, security and governance
2022
Abstract In these last decades, the awareness that soil is a very important resource for humans has noticeably increased. Many actions and initiatives to promote soil governance, aiming at sustainable soil management and soil security have been undertaken by several national and international institutions and in many countries. Analysis of the changes of soil perception over the centuries allows highlighting a perfect harmony between the evolution of soil awareness and the level of knowledge and technology achieved by humans during their history and evolution. Notwithstanding these many achievements, soils continue to be scarcely considered in politics and society. We suggest some thoughts …
Sustainable vineyard floor management: An equilibrium between water consumption and soil conservation
2018
Abstract Sustainable vineyards soil management can help to mitigate the negative effect of intensive agriculture on soil ecosystem for the achievement of the sustainable development goals. Cover crops use as cover management in vineyard could be considered as nature based solution for soil restoration and proper water management. Cover crops (CC) provide many ecosystem services through carbon sequestration and climate change regulation, water purification and soil protection. However, a holistic approach is needed to understand the maximum potential ecosystem service that can be provided in different soil and climatic condition also considering vineyard needs. The current knowledge of CC ma…
Application of Environmental Management Systems (EMS) to Natural Parks and reserves
2006
Natural parks and reserves have to face problems concerning the conservation of their natural resources. Citizens and firms often perceive the institution of new protected areas more as a bind or a restriction to their activities than an added value of the territory. Following the principles of sustainable development, it is necessary to integrate the environmental protection with the needs of neighbouring urban areas and production sites. The implementation of an Environmental Management System (EMS) according to international standards (ISO 14001, EMAS) can support the Park administration in their complex management activities. This paper analysed the criticisms related to the application…
Critical range of soil organic carbon in southern Europe lands under desertification risk.
2021
Soil quality is fundamental for ecosystem long term functionality, productivity and resilience to current climatic changes. Despite its importance, soil is lost and degraded at dramatic rates worldwide. In Europe, the Mediterranean areas are a hotspot for soil erosion and land degradation due to a combination of climatic conditions, soils, geomorphology and anthropic pressure. Soil organic carbon (SOC) is considered a key indicator of soil quality as it relates to other fundamental soil functions supporting crucial ecosystem services. In the present study, the functional relationships among SOC and other important soil properties were investigated in the topsoil of 38 sites under different …
An Italian input–output model for the assessment of energy and environmental benefits arising from retrofit actions of buildings
2013
Abstract The paper presents an energy and environmental extended input–output model combined with the life cycle assessment, applied to assess the energy and environmental benefits arising from the Italian policy of tax deduction for energy retrofit actions of buildings. The study allowed to assess the advantages due to the above policy, taking into account both direct and indirect energy saving and avoided CO 2 emissions obtained with the retrofit actions and indirect energy consumption and related CO 2 emissions due to the realization of the above actions. Moreover, the authors defined an original model to assess the indirect rebound effect caused by the energy saving actions. The obtaine…
Transitioning towards a Sustainable Wellbeing Economy—Implications for Rural–Urban Relations
2021
This article focuses on the question of how a shift from a narrow economic perspective to a wider sustainable wellbeing focus in regional development strategies and actions might change rural–urban relations. A brief review of relevant research and discourses about economic development models provides the foundation for the analysis. The review leads to the development of an analytical framework that puts the notion of sustainable wellbeing at its center. The criteria included in the analytical framework are then used to assess the current situation, challenges and perceived ways forward based on data and analyses from 11 European regions. The focus of the analysis is on different exp…
