Education for sustainable development in early chilhood education in Spain : evolution, trends and proposals
2013
This article analyses how the sustainability culture has evolved in the early childhood education setting within the Spanish education system with official documents and the sustainability training received by teachers who intervene in this stage of education since these teachers' degrees have been adapted to the European Higher Education Area.Early childhood education in Spain is an individual stage to educate children aged up to six years (two main cycles: 0–3 and 3–6 years). It is important to verify if this stage of education includes curricular content that is designed to develop attitudes, behaviours and lifestyles that are in keeping with sustainability values.We conclude that it is …
Materials for sustainable architecture in the Mediterranean region
2016
There has been recent increased use of earth for construction of buildings in developed countries, largely because of concerns with the environmental impact and embodied carbon from fired bricks and cement based products. Of all forms of earth construction, the widest impact on modern construction is likely to come from commercially produced unfired earth masonry where large scale production can significantly reduce costs. The use of traditional materials in the Mediterranean area needs to be reassessed with a thought given to environmental sustainability, but also with an eye to the reappropriation of the predominantly massive nature of Mediterranean architecture. This article contemplates…
Life cycle assessment of a new industrial process for sustainable construction materials
2023
One of the key sectors for the green transition of European countries is construction, that is more and more asked to evolve towards innovative ecological binders and green cost-effective processes. The construction sector is highly energy intensive, and the cement production is one of the main sources of environmental pollution in the world. In this regard, GeoPolymers (GP) seem to be promising for a sustainable replacement of cementitious materials. Therefore, the Life Cycle Assessment (LCA) of the industrial production of different formulations of Geopolymer Concrete (GC) was performed in this study after scaling up the Life Cycle Inventory (LCI) from a laboratory scale to an industrial …
El desarrollo local sostenible en clave estratégica
2008
This article considers local development from the point of view of the ecological sustainability of the economic process. We put forward ideas that help to provide a view of local development that is in line with the concept of sustainable development. First we take a strategic approach to the idea of economic development as a material process, describing the capacities on which it is based. We then highlight the fundamental features of the strategic view of local development, which has created wealth over the last two decades, and the trends that question the current model of development. All of this will help us justify the need for a change of model and the importance of local involvemen…
Sustainable tourist development in Italian holiday destinations
2008
This paper argues that tourism, will become a major activity in a modern welfare state, which will have serious consequences for environmental sustainability. This issue calls for an assessment of the pros and cons of the ecological efficiency of tourism. We propose an overall efficiency indicator that comprises both a sustainable tourism index and an economic efficiency index. Based on a data set for Italian provinces and using Activity Analysis, a quantitative assessment of the relative position of Italian tourist destination areas is made from the perspective of sustainable tourism.

Optimal Sustainable Policies Under Pollution Ceiling: the Demographic Side
2014
AD; International audience; We study optimal sustainable policies in a benchmark logistic world (where both population and technological progress follow logistic laws of motion) subject to a pollution ceiling. The main policy in the hands of the benevolent planner is pollution abatement, ultimately leading to the control of a dirtiness index as in the early literature of the limits to growth literature. Besides inclusion of demographic dynamics, we also hypothesize that population size affects negatively the natural regeneration or assimilation rate, as a side product of human activities (like increasing pollution, deforestation, ...). We first characterize optimal sustainable policies. Und…
Life cycle assessment of low temperature asphalt mixtures for road pavement surfaces: A comparative analysis
2018
The increasing fuel consumption demand, the accelerated pressure imposed by the depletion of 5 scarce raw materials and the urgent environmental protection requirements are forcing the change of 6 pavement industry and academia community’s research endeavors towards the development of low 7 emissions road paving technologies able to significantly reduce mixing and compaction temperature as 8 well as the consumption of virgin raw materials. One set of relatively recent technologies in the field of 9 pavement materials that aims at addressing those concerns are the warm mix asphalt (WMA). In fact, 10 they have the potential to allow the reduction of energy consumption and airborne emissions d…
Adapting to High Temperatures: Effect of Farm Practices and Their Adoption Duration on Total Value of Crop Production in Uganda
2021
In this article, we use spatially granular climate data merged with four waves of household survey data in Uganda to examine empirically the relationships among high temperatures, total value of crop production, and the adoption and adoption duration of two sustainable agricultural practices (organic fertilizer adoption and maize–legume intercropping). We do this using a fixed-effect model with instrumental variables to address potential endogeneity issues. Our findings indicate that the adoption of these practices has a positive effect on the total value of crop production, and such effect increases monotonically as temperatures increase from long-term averages. Moreover, the number of yea…
Lo sviluppo sostenibile della pesca nella marineria di Mazara del Vallo
2011
In a place like Sicily, where sea fishing and port activities are part of the territory, history and culture, fishery has always been vital to man and, for this reason, today it must be studied, protected and helped in the difficult transition towards long-term sustainability. Fishing is a driving sector for Mazara economy both for number of working days during the fishing season, and for industrial activities operating around this field (transformation, packaging, and distribution). A micro-economic analysis was carried on a sample of fishing enterprises in order to analyze the problems of the here studied seamanship. The analysis is based on the employers’ interviews. The collected data h…
Heterogeneous effects of sustainable agriculture practices: micro-evidence from Malawi
2020
Abstract Are the effects of sustainable agricultural practices heterogeneous across agro-ecology and wealth in Malawi? Would a wealth-enhancing policy be associated with increased effectiveness of these practices? Focusing on a nationally representative set of Malawian agricultural households, the article answers the above questions by employing plot-level panel data matched with a set of geo-referenced rainfall and temperature records. The findings suggest a positive correlation between aggregate yield and the adoption of organic fertilizer. A similar result holds for legume intercropping and for hybrid seeds, which are associated to reductions in yield volatility between the two waves. Ne…
