Comment réduire les émissions de CO2 du transport de fret en France ? Evaluation socio-économique de trois politiques publiques
2018
France must implement voluntarist policies in order to reduce CO2 emissions, which raises questions regarding the effectiveness of competing options and their costs, for both public finances and society. This paper estimates abatement costs of one ton of CO2 from three scenarios aimed at softening the environmental impacts of freight moved by trucks. Hybrid trucks may generate large CO2 savings (5.7 Mt/year in 2030), at a moderate discounted abatement cost (88 €/t). The option based on natural gas for vehicles leads to a similar abatement cost and to lower environmental gains (3.2 Mt/year in 2030). Whilst inducing small CO2 savings (0.2 Mt/year in 2030), megatrucks present a negative discou…
From impact refugees to deterritorialized states: Foresighting extreme legal-policy cases in asteroid impact scenarios
2022
Throughout recorded history, humans have crossed national borders to seek safety in nearby countries. The reasons for displacement have been generated by phenomena of terrestrial origin, but exposure to unexpected extra-terrestrial threats poses a different scenario. An asteroid impact warning implies a change of paradigm which would represent a historic precedent. In this regard, the analogies with natural disasters must be considered, along with multiple possible scenarios, and legal aspects related to (a) the legal framework to regulate this situation; (b) the action and responsibility of the states; and (c) the definition of impact refugee and the reconfiguration of traditional concepts…
Evaluating the Regional Impact of a New Road on Tourism
2004
Ferri J. (2004) Evaluating the regional impact of a new road on tourism, Reg. Studies 38, 409–418. The aim of this work is to establish whether the opening of a motorway that extends along the east coast of Spain has significantly contributed to expanding hotel tourism in the Valencia region. Some of the most important tourist destinations in Spain, both domestic and international, are located in this region, such as Benidorm, Peniscola and Gandia. The A-7 motorway, also part of the E-15 road network, is not only a faster and safer means of road communication for tourists but also provides a new gate to Europe, connecting with other motorways. Using monthly data on nights spent in hotels by…
Caging techniques for field exposures of fish to chemical contaminants
2005
The article reviews current state-of-the-art to conduct fish caging as an assessment and monitoring technique in aquatic toxicology. A multitude of scientific, practical and management factors influence and may restrict how field research is carried out. For many purposes the advantages of transplant fish caging outweigh the alternative methodologies of impact studies of xenobiotics. However, besides mortality, virtually no study has evaluated the physiological consequences of caging fish. It is not known how caging itself affects the responses of fishes to chemical pollution. The used caging densities are commonly too high. However, with the aid of variables describing physiological stress…
The impact of economic, social and political factors on the landscape structure of the Vidzeme Uplands in Latvia
2005
Abstract Changes in landscape structure in a typical part of the Vidzeme Uplands in central Latvia during the 20th century are analysed and anticipated changes in the 21st century are projected. Forest areas gradually increased in the Vidzeme Uplands over the course of the 20th century. This increase was associated with several factors: the economic policy in Latvia during the 1930s, the exile of farmers in 1940 and 1949 after the Soviet occupation of Latvia, the aggregation of land into collective farms, the amalgamation of small collective farms, the formation of large-scale Soviet collective farms, and widespread land melioration. Since land reform in the 1990s, following the restoration…
The socioeconomic impacts of local energy programmes: a case study of Avrig, Romania
2014
Purpose – The purpose of this paper is to investigate the expected economic and social effects of the “Local Energy Plan” – a programme of the local administration that aims to transform the Romanian town Avrig until 2020 into an energy independent town relying exclusively on renewable energy resources. Design/methodology/approach – The study uses a mixed-method approach to investigate the effects of a small town's transition to renewable energy. This approach consists of a series of in-depth interviews with the local authorities, investors, other representatives of the business sector and citizens of Avrig and economic modelling to determine the direct effects generated by the implementat…
The effectiveness of rural versus urban nonprofit organisations in the Democratic Republic of Congo
2017
The Democratic Republic of Congo (DRC) is a country with high natural resources, but it has suffered from decades of civil wars and social turmoil, being heavily aid-dependent. In the DRC, several Nonprofit Organisations (NPOs) are major players in fighting poverty and enhancing welfare. This research aims to analyse the effectiveness of small NPOs in improving poor peoples’ lives through health, education, and economic activities. Two NPOs working in the DRC, one in a rural and the other in an urban area, are compared by researching the aid sites and surveying 201 households (aid beneficiaries). Our case observations and the survey results facilitate analysing the mission accomplishment, e…
The Economic Impact of Visitors at Major Multi-sport Events
2005
Abstract This paper examines the economic impact of major multi-sport event on affected people. Their spending increases the economic benefit for the city and region staging the event. Therefore a theoretical differentiation of movements of persons affected by the event was done. A model was worked out to detect the regional primary economic impact through these people. This primary impact can be used in any model of economic impact analysis, such as input–output frameworks or multiplier theory. The complexities in considering the right persons and their spending are analysed and described in detail. A special focus is placed on the evaluation of opportunity costs on people that get crowded…
The Oblivion of Demography in Sustainability’s Studies
2017
[RESUMEN] A lo largo de la historia del Homo sapiens, su número se ha mantenido muy reducido y hubo que esperar a principios del siglo XIX para que alcanzara los mil millones. Se inició entonces un rápido crecimiento y durante el siglo XX la población mundial casi se cuadriplicó, superando los 6000 millones, lo que llevó a estudiar, con lógica preocupación, los posibles efectos de esta explosión demográfica sobre el conjunto de la biosfera y sobre la propia especie humana. Hoy, sin embargo, cuando se han sobrepasado los 7500 millones y la población mundial sigue aumentando en unos 80 millones cada año, la problemática demográfica ha dejado de tener una presencia relevante en los estudios y …
Percepciones de los residentes sobre el turismo deportivo: impactos, calidad de vida y apoyo al sector
2020
El sector del turismo deportivo recibe cada vez una mayor atención por parte de los distintos agentes sociales, teniendo un alto impacto en distintas esferas de la sociedad. El turismo no sólo afecta a las actitudes de los residentes hacia su desarrollo, sino también a su calidad de vida en general. Una vez que una comunidad o población se convierte en un destino turístico, la calidad de vida de los residentes locales se ve afectada por el desarrollo del mismo. Por consiguiente, es relevante conocer cuáles son las percepciones de los residentes respecto al impacto que causa el turismo deportivo. Por ello, el objetivo del presente estudio es analizar las percepciones de los residentes de Gra…
