Marine Policy | Year: 2015

The increasing demand for fish products and the stagnation of capture fisheries has promoted the growth of aquaculture globally, leading to a significant increase in socio-environmental conflicts mainly in relation with finfish aquaculture. Despite this significant global growth, the European aquaculture sector has instead experienced stagnation in the last decade. While European public authorities are currently encouraging the growth of the sector in order to change this trajectory, conflicts over finfish aquaculture have nonetheless already taken place in Europe. Based on peer-reviewed articles, gray literature, and 27 in-depth interviews, this article analyzes such conflicts in Europe in the last two decades by examining their localities, characteristics, the different actors involved, and the arguments of these actors. In this way, it explores the relation of these conflicts to environmental justice theory. Findings highlight that resistances to marine finfish aquaculture in Europe do not have a purely conservationist motivation, but rather entail a complex set of claims supported by various actors. These include demands for an even distribution of burdens and benefits resulting from marine finfish aquaculture, the right to be recognized as relevant stakeholders, an effective participation process where actors have access to adequate and transparent information and a real capacity to influence the decision-making, and to be able to maintain their social functioning. Based on this analysis, the article derives political lessons for future European marine policies. © 2014 The Authors. Source

Waste Management | Year: 2012

In this paper, the material and spatial characterization of the flows within a municipal solid waste (MSW) management system are combined through a Network-Based Spatial Material Flow Analysis. Using this information, two core indicators are developed for the bio-waste fraction, the Net Recovery Index (NRI) and the Transport Intensity Index (TII), which are aimed at assessing progress towards policy-related sustainable MSW management strategies and objectives. The NRI approaches the capacity of a MSW management system for converting waste into resources through a systematic metabolic approach, whereas the TII addresses efficiency in terms of the transport requirements to manage a specific waste flow throughout the entire MSW management life cycle. Therefore, both indicators could be useful in assessing key MSW management policy strategies, such as the consecution of higher recycling levels (sustainability principle) or the minimization of transport by locating treatment facilities closer to generation sources (proximity principle). To apply this methodological approach, the bio-waste management system of the region of Catalonia (Spain) has been chosen as a case study. Results show the adequacy of both indicators for identifying those points within the system with higher capacity to compromise its environmental, economic and social performance and therefore establishing clear targets for policy prioritization. Moreover, this methodological approach permits scenario building, which could be useful in assessing the outcomes of hypothetical scenarios, thus proving its adequacy for strategic planning. © 2012 Elsevier Ltd.

Energy Policy | Year: 2010

This paper reviews the empirical literature concerning the direct rebound effect in households; it briefly analyzes the main theoretical and methodological aspects, and finally estimates the magnitude of direct rebound effect for all energy services using electricity in households of Catalonia (Spain) using econometric techniques. The main results show an estimated direct rebound effect of 35% in the short term and 49% in the long term. The existence of a rebound effect reduces the effectiveness of energy efficiency policies. © 2009 Elsevier Ltd. All rights reserved. Source

Water Resources Management | Year: 2011

Water supply restrictions due to droughts generate significant costs to many economic agents. Although these costs are difficult to assess, this article presents a methodology to quantify, from a general equilibrium perspective, the macroeconomic impact of water supply restrictions through the estimation of aggregate production functions that include water consumption by sectors. Simulations with an Input-output model suggest a loss of 0. 34% of GDP in the case of modest restrictions on the water supply and 2. 8% in the case of more extreme restrictions for 2005 for the Catalonia region in Spain. © 2011 Springer Science+Business Media B.V.

Ecological Modelling | Year: 2011

Energy efficiency policies have a special importance within carbon emission reduction policies to mitigate the climate change effects. However, potential reductions of energy consumption and, consequently, its resulting emissions, can be offset through the so called " rebound effect" The concept of " rebound effect" refers to a set of mechanisms whereby the improvement of efficiency reduces the cost of the energy service and this results in the household energy consumption rising and totally or partially negating the reduction achieved by the energy efficiency improvement. This paper provides a methodology to estimate the static direct plus indirect rebound effect of energy efficiency improvements in the use of energy in households. It is based on the combination of econometric estimations of energy demand functions, re-spending modelling and generalised intput-output of energy modelling. It also provides estimations for Catalonia. © 2011 Elsevier B.V. Source
