Environmental sustainability and energy assessment of bituminous pavements made with unconventional materials
2019
The increasing sensibility towards the questions related to climate change has made the scientists and technicians aware of the need to incorporate the principles of sustainable development into the road construction sector. In this view, recycled materials in road pavements and technologies to decrease the overall carbon footprint have become more and more important. Based on the ISO14040 series, the overall purpose of this study is calculating, by means of a systemic approach, the life-cycle energy and the carbon footprint of road pavement solutions. To this aim, several alternatives in terms of bituminous mixtures (warm mix asphalt, reclaimed asphalt pavements, waste plastics) were consi…
Normative Principles for Adaptation to Climate Change Policy Design and Governance
2012
Recognising climate change as a highly complicated and basically unstructured problem, the purpose of this paper is to suggest a theoretical frame supplemented with practical elements for adaptation to climate change policy design in the context of the requirements of sustainable development normative principles and criteria. The paper attempts to break the business-as-usual approach to policy design and decision-making practice concerning complicated and unstructured problems. The first recommendation for achieving that purpose is the application of a systemic and analytical approach to the elaboration process of adaptation policy, required by the United Nations’ Framework Convention on Cl…
Carbon Footprint Analysis: Towards a Projects Evaluation Model for Promoting Sustainable Development
2013
Abstract Climate change and global warming are internationally recognized as current issues, driving negative effects on humanity, and being mainly caused by GHG emissions generated both from industrial activities, and from other anthropogenic activities. Restoring the ecological balance requires urgent action to reduce GHG emissions. In this respect, the European Union has set the target to reduce the GHG emissions by 20% until 2020, compared to 1990 level. This paper presents a methodology to develop a model for carbon footprint calculation, for assessing and reducing GHG emissions generated by European funds financed projects.
Urban Smartness: Tools and Experiences
2014
The necessary steps to build a different city that combines both sustainable development and urban quality include understanding of the events that emerge in different territories, identifying the appropriate actions, policies and finding innovative tools and procedures.
Climate change, consumer lifestyles and legitimation strategies of sustainability-oriented firms
2021
Abstract This study explores the links between climate change, consumer lifestyles, and legitimation strategies of sustainable firms. Our findings offer new insight into this under-researched area based on qualitative case studies of four Nordic firms operating in industrial and consumer contexts. We find that climate change consciousness is a major driver for all case firms’ sustainability-focused operations, but the dynamics differed. Achieving sociopolitical legitimacy emerges as an important factor for the case firms operating in the energy sector, especially as it connects to government incentives and regulative pressures. However, cognitive legitimacy is increasingly important for the…
Soil Quality Characterization of Mediterranean Areas under Desertification Risk for the Implementation of Management Schemes Aimed at Land Degradatio…
2020
Soil is a key component of ecosystems as it provides fundamental ecosystem functions and services, first of all supporting primary productivity, by physical, chemical and biological interaction with plants. However, soil loss and degradation are at present two of the most critical environmental issues. This phenomenon is particularly critical in Mediterranean areas, where inappropriate land management, in combination with the increasingly harshening of climatic conditions due to Climate Change, is leading to significant land degradation and desertification and is expected to worsen in the future, leading to economic and social crisis. In such areas, it is of fundamental importance to apply …
Barriers and Bridges for Landscape Stewardship and Knowledge Production to Sustain Functional Green Infrastructures
2018
Sustainable landscapes and regions require both stewardship and management to sustain the composition, structure and function of ecosystems as a base for delivering human benefits. This complex is captured by the topic of ecosystem services. To deliver these, the concept green (or blue) infrastructure emerged as a tool for spatial planning of networks of natural and semi-natural areas. Such planning requires evidence-based knowledge about both ecological and social systems. For ecosystems, states and trends need be monitored, and improved knowledge must be developed about ecological tipping points for assessment of sustainability, as well as measures for conservation, management and restora…
Distribution de la température et de la végétation en Baie du Rois, Svalbard (79°), mise en place d'une approche spatiale formalisée
2006
International audience; Le changement climatique est un problème majeur, surtout en Arctique. Ce constat global doit être précisé afin d'appréhender les conséquences du phénomène car son impact se module dans l'espace selon les caractéristiques propres à chaque milieu. L'aire d'étude est située au Svalbard où des données, de différentes sources, sont collectées sur le terrain. Elles sont ensuite traitées au sein d'un système d'information géographique afin de modéliser les variations spatiales à grande échelle de la température et de la végétation.
ATTEMPTS TO ISOLATE C'3 ACTIVITY FROM PIG SERUM.
1965
Gli autori descrivono un metodo per l'isolamento del terzo componente del complemento dal siero di maiale, basato sulla possibilita di provocare, per aggiunta di lisozima, passaggio in soluzione del C′3 precipitato insieme ad altre proteine in seguito all'aggiunta di opportune quantita di « Liquoid » al siero.
The first record ofDinesus(Trilobita, Dinesidae) in the Cambrian of the Mediterranean region
2011
An important problem facing inter-regional correlation in the Cambrian is the scarcity of shared taxa between different palaeogeographic domains. Currently, species of the Corynexochida are proposed as tools to define the base of Cambrian Series 3. However, few Mediterranean Corynexochida species are known. A specimen of Dinesus truyolsi comb. nov. from the middle Cambrian of Spain represents the first record of this genus in the Acadobaltic province. Erbia and Tingyuania are accepted as junior subjective synonyms of Dinesus, and we now recognize 22 species within this genus. Dinesus has been found previously in lower to middle Cambrian strata of Australia, Russia, Kazakhstan, North America…
