How alternative food networks work in a metropolitan area? An analysis of Solidarity Purchase Groups in Northern Italy
2019
AbstractOur paper focuses on Solidarity Purchase Group (SPG) participants located in a highly urbanized area, with the aim to investigate the main motivations underlining their participation in a SPG and provide a characterization of them. To this end, we carried out a survey of 795 participants involved in 125 SPGs in the metropolitan area of Milan (Italy). Taking advantage of a questionnaire with 39 questions, we run a factor analysis and a two-step cluster analysis to identify different profiles of SPG participants. Our results show that the system of values animating metropolitan SPG practitioners does not fully conform to that traditionally attributed to an alternative food network (AF…
Climate change, ethics and sustainability: An innovative approach
2018
Our goal in this article is the analysis of the state of affairs, regarding the phenomenon of climate change and its impact in different areas. We synthesize the various approaches available in the scientific debate on this subject, mainly the one that affirms the existence of global warming and the current approach, which denies it. Beyond the controversy, what seems to be evident is that there is a multifactorial causality in a phenomenon that affects anthropogenic factors a well. Since some environmentalisms exclude the human being in their consideration of the ecosystem, and if they do, they accommodate man in their approaches always as a variable that distorts and deteriorates the envi…
Strategic Vision of a Euro-Mediterranean Port City: A Case Study of Palermo
2013
Italian harbours assume a decisive role in order to develop a Euro-Mediterranean web for maritime transportation. The geostrategic position of the Italian peninsula can be seen as a logistic platform at the centre of the maritime trades in the Mediterranean area, giving to its port cities the role of gateway of economic flows. The port poles, meant as hubs, are able to attract investments and create economic growth and territorial development through new operative models of urban usage and management. The management policies have to consider the environmental characteristics and distinctive features, respecting the identity of the places as concrete evidence of history, a source of intellec…
Evaluating the Sustainability in Complex Agri-Food Systems: The SAEMETH Framework
2015
During the last few years, the definition of sustainability and the translation of its general principles into practical and operative tasks have come into the foreground of scientific research and political agendas throughout the world. The understanding and the evaluation of the environmental, social and economic performances of complex agricultural food systems is probably the real challenge, and the design of more sustainable alternatives has been recognized as necessary for a correct territorial management. This study’s primary goal is the proposition of an interpretive structure “Sustainable Agri-Food Evaluation Methodology” (SAEMETH), able to guide the evaluation of the sustainabilit…
Improving the sustainability of transportation: environmental and functional benefits of right-turn by pass lanes at roundabouts
2015
The functional performances of conventional roundabouts (single-lane and multi-lane) and innovative roundabouts (spiral, flower, C and turbo) can be improved through right-turn bypass lanes controlled by stop, yield or free-flow signs. The article presents evaluations of the emissions of air pollutants (carbon dioxide, nitrogen oxides, particle pollution (PM10 and PM2.5)), fuel consumption and construction, management, energetic and environmental costs in roundabouts without or with bypass lanes (controlled by stop, yield or free-flow). The suggested methodology has a general character and can be applied as a multi-parametric criterion for choosing road intersections, although, in the prese…
Efeitos das práticas verdes na lealdade: proposta de um modelo para o segmento hoteleiro colombiano
2021
Resumen El propósito de este estudio fue analizar la incidencia de las prácticas verdes como impulsoras para generar confianza, satisfacción y lealtad en los huéspedes. Para ello, a partir de una muestra de 302 huéspedes de hoteles en Bogotá, Colombia, se estimó un modelo de ecuaciones estructurales a través de la regresión de mínimos cuadrados parciales. Los resultados obtenidos evidencian que las prácticas sostenibles contribuyen al aumento de la confianza y la satisfacción de los huéspedes, y que estas, a su vez, influyen positivamente en su lealtad hacia el hotel. Además, dichos resultados ponen de manifiesto que una comprensión más profunda del perfil de los turistas medioambientalment…
Economic and Financial Comparison between Organic and Conventional Farming in Sicilian Lemon Orchards
2015
Sicily has a long tradition in citrus fruit cultivations that with vineyard and olive tree represent the main Mediterranean tree crops. In this paper we have evaluated the economic and financial sustainability of lemon production, both in organic farming and in conventional farming
Análisis bibliométrico y sistémico de la relación entre la gestión y el carbono
2022
[EN] This paper aims to present a bibliometric and systemic analysis of the Bibliographic Portfolio (BP) jointly examining the literature related to topics like “Greenhouse gas,” mainly carbon, and “Management,” as published in databases data such as Web of Science and Scopus in the field of economic and social sciences. The Knowledge and Constructivist Development Process methodology —Proknow-C— was used to establish the final portfolio and through the VosViewer program were mapped the various groups or relationships between the studied literature. The paper presents the theoretical and methodological aspects focusing on the areas and countries of study and highlighting the most relevant a…
The Impact of the Poland Foreign Trade On Its Real CO2 Emissions
2017
CO2 emissions are a global problem. This means that nothing or very little will change if only particular countries are involved. The purpose of this paper is the attempt to show the real CO2 emissions of the Poland as well as the impact of its trade on CO2 emissions in other countries in the world and in the EU in 2015. This study was conducted on the group of countries that are the major emitters of CO2 in the world including most of the EU members. Actual CO2 emissions were achieved by applying the actual emission factor. This takes into account the transfer of CO2 in export products and services as well as those imported by particular countries. It has turned out that the real CO2 emiss…
Como as práticas ecológicas e o desperdício de alimentos influenciam o capital de marca do restaurante?
2020
Resumen El presente trabajo tuvo por objetivo evaluar la incidencia de las prácticas verdes, la innovación sostenible y el manejo del desperdicio alimentario en la construcción del capital de marca de los restaurantes. A partir de una investigación cuantitativa dirigida a responsables de restaurantes en Ecuador, se obtuvieron 120 cuestionarios válidos que permitieron estimar un modelo de ecuaciones estructurales a través de la regresión de mínimos cuadrados parciales. Los resultados obtenidos evidencian que las prácticas verdes orientadas a la formación del empleado y la innovación sostenible contribuyen significativamente a la reducción del desperdicio alimentario, que, a su vez, junto a l…
