The Unintended Side Effects of Bioplastics: Carbon, Land, and Water Footprints

2020

(One Earth 3, 45–53, July 24, 2020) In the originally published version of this article, the authors inadvertently used global volumes of bioplastics in plastic packaging instead of European volumes for Figure 1C. After noticing this, the authors recalculated European bioplastic packaging consumption, and as such, Figure 1 and its legend have been corrected in the online article (as shown below) to reflect all data sources used for estimating European bioplastic volumes in Figure 1C. In the Experimental Procedures, the Data and Code Availability section has been updated, and the section “Estimation of European Bioplastic Volumes” has been added. Additionally, reference 69 is new, and two in…

Aspects of phosphorus transfer from soils in Europe

2008

Imbalanced nutrient management has caused soil phosphorus (P) to become an environmental rather an agronomic problem in more economically developed countries. This subject has been the topic of numerous journal special issues, conferences, and reviews but we consider yet another review of this subject is necessary with the main target of providing a point of view on non-point transfer from soils and control strategies for an improved environmental management of P. This review considers the causes of the excessive P transfer from soil to surface water in Europe and the scientific knowledge necessary to develop control strategies. There has been an increasing trend towards the P-research inte…

Assessing the marginal cost of reducing greenhouse gas emissions in the English and Welsh water and sewerage industry: A parametric approach

2021

Abstract Reducing greenhouse gas (GHG) emissions involves effort from different sectors of the economy, including the water and sewerage industry. This study estimates the marginal cost of curtailing GHG emissions in the water and sewerage industry using stochastic frontier analysis techniques for a sample of ten English and Welsh water and sewerage companies over the 2010–2019 period. Results illustrated that the average marginal cost of reducing GHG emissions was 0.181 £/Kg CO2 equivalent. The marginal cost estimated notably differs across companies and over time. Findings further illustrate the impact of water companies' operating characteristics on the marginal cost of reducing carbon e…

The Market Reorientation of Farms: The Case of Olive Growing in the Nebrodi Area

2014

In addition to safeguarding the landscape, olive growing makes a unique contribution to protecting the environment and the agricultural ecosystem. Olive growing in mountainous and hilly areas is severely constrained by structural limitations. Rural tourism can be a potential strategy to increase the competitiveness of olive-growing activities. After an initial analysis of the relationship between landscape, tourism, and olive growing, this study focused on olive growing in the Nebrodi area. In particular, we examined two case studies of olive farms to analyze the related production costs and market positioning strategies.

NUEVAS FORMAS DE REPORTING CORPORATIVO: INFORMACIÓN SOBRE LA HUELLA DE CARBONO EN ESPAÑA

2018

RESUMEN A raíz del Protocolo de Kioto, España crea el Registro Nacional de Huella de Carbono, Compensación y Proyectos de Absorción de Dióxido de Carbono mediante el Real Decreto 163/2014. Ello se constituye en una iniciativa pionera para potenciar que las empresas españolas den visibilidad a su compromiso en la reducción de sus emisiones de Gases de Efecto Invernadero (GEI). Bajo este contexto, la presente investigación explora los determinantes de la adhesión al Registro Nacional de Huella de Carbono español. Se realiza un estudio exploratorio de las características de las primeras empresas españolas que decidieron inscribir su huella de carbono, a través de un modelo de regresión logísti…

Magnéli oxides as promising <em>n</em>-type thermoelectrics

2014

The discovery of a large thermopower in cobalt oxides in 1997 lead to a surge of interest in oxides for thermoelectric application. Whereas conversion efficiencies of p-type oxides can compete with non-oxide materials, n-type oxides show significantly lower thermoelectric performances. In this context so-called Magneli oxides have recently gained attention as promising n-type thermoelectrics. A combination of crystallographic shear and intrinsic disorder lead to relatively low thermal conductivities and metallic-like electrical conductivities in Magneli oxides. Current peak-zT values of 0.3 around 1100 K for titanium and tungsten Magneli oxides are encouraging for future research. Here, we …

Renewable energy sources: a Mediterranean perspective

2010

Southern Mediterranean countries are growing very fast. Globally, the evolution of economic and social indicators in the area is positive, since significant progresses have been registered in the field of economic as well as human development.

Analysis of intermittent supply systems in water scarcity conditions and evaluation of the resource distribution equity indices

2007

Generally, urban water distribution shortage situations are solved by introducing discontinuous service and rationing the available water resources. This approach is widely adopted, not only in developing countries but also in developed ones, for solving short term scarcity conditions which can be caused by unpredicted drought periods. Intermittent distribution has the advantage of requiring small financial efforts but it leads to network operating conditions that are very far from the usual design ones. With the aim to analyse and describe the water supply network behaviour in intermittent conditions, a network hydraulic model has been set up in which both user and manager dependent regula…

ECONOMIC EVALUATION OF AQUACULTURE INVESTMENTS UNDER CONDITIONS OF RISK AND UNCERTAINTY IN THE MEDITERRANEAN SEA

2014

This study aims to analyze, from a technical and ec onomic point of view, the choice between alternative investments in aquaculture under condit ions of risk and uncertainty. In particular, a comparative analysis has been conducted between an inshore and an offshore farm producing European sea bass in the Mediterranean Sea. The app lied model refers to the theory of subjective probability, assigning a different probability to e xpected incomes during the investment period. Resul ts show an economic convenience of inshore with respect to offshore farming.
