Brasil: la sostenibilidad de la agroindustria de la caña de azúcar y las oportunidades de exportación de bioetanol a la Unión Europea

Portocarrero, Izabel Rigo - HAL - 2013

En Brasil, el bioetanol, juntamente con el bagazo de la caña, representa el 18,1% de la oferta interna de energía, lo que lo califica como la segunda mayor fuente de energía en una matriz energética compuesta por un 45% de energías renovables, mientras que la media mundial llega al 14%. Se...

Do food scares explain supplier concentration ? An analysis of EU agri-food imports

Jaud, Mélise; Cadot, Olivier; Suwa-Eisenmann, Akiko - HAL - 2009

their agri-food products from a wider range of suppliers), while geographical concentration increases at the intensive … food alerts at the EU border that had never been exploited before. After coding it into HS8 categories, we regress the … incidence of food alerts by product on determinants including exporter dummies as well as HS8 product dummies. Coefficients on …

Transport, health and climate change: Deciding on the optimal policy

Cabantous, Laure; Chanel, Olivier; Vergnaud, Jean-Christophe - HAL - 2010

Transport generates many externalities, some related to atmospheric pollution. In this paper, we focus on two: greenhouse gases, and local pollution. In the search for optimal transport policies, these two externalities have usually been analysed separately. Here, we study them jointly, in a...

ECONOMIC EXPERTISE AND DECISION-MAKING IN CONTROVERSIAL UNIVERSES

Godard, Olivier - HAL - 1996

There are two questions to be considered: a) to which extent the type of framing which may be appropriate for scientific explorations of some issues can also be relevant in a decisionmaking context, in which achieving an agreement among stakeholders is the key problem? b) what is the practical...

Building world narratives for climate change impact, adaptation and vulnerability analyses

Hallegatte, Stéphane; Valentin, Przyluski; … - HAL - 2011

The impacts of climate change on human systems depend not only on the level of emissions but also on how inherently vulnerable these systems are to the changing climate. The large uncertainties over future development and structure of societies and economies mean that the assessment of climate...

Envisioning innovative groundwater regulation policies through scenario workshops in France and Portugal

Rinaudo, Jean-Daniel; Montginoul, Marielle; Varanda, Marta - HAL - 2012

Groundwater management policies will need to be revised in many Mediterranean countries, in light of the impact of climate change and the increasing demand for water. In this paper, we analyze stakeholder perceptions of three groundwater policy scenarios which respectively assume a strengthening...

Geoengineering as an alternative to mitigation: specification and dynamic implications

Sterck, Olivier - HAL - 2011

Geoengineering, i.e. the use of artificial techniques aiming at cooling the planet, is increasingly considered as a realistic alternative to emission mitigation. Several methods are promising for their capacity to quickly halt global warming at a moderate cost. Such cheap technologies might be...

How long can excess pollution persist? The non-cooperative case

Hénin, Pierre-Yves; Schubert, Katheline - HAL - 2008

This paper describes a world composed of two (groups of) countries, which derive their utility from a polluting activity and from the enjoyment of a common environmental quality. The initial situation is both suboptimal and unsustainable: pollution leads to a continuous deterioration of...

Using Maps of City Analogues to Display and Interpret Climate Change scenarios and their uncertainty

Kopf, Sebastian; Ha-Duong, Minh; Hallegatte, Stéphane - HAL - 2008

We describe a method to represent the results of climate simulation models with analogues. An analogue to a city A is a city B whose climate today represents A's simulated future climate. Climates were characterized and compared non-parametrically, using the 30-years distribution of three...

Drought and Civil War in Sub-Saharan Africa

Couttenier, Mathieu; Soubeyran, Raphaël - HAL - 2011

This paper contributes to the heated debate on the link between climate and civil war. We exploit a large dataset of a drought index commonly used in hydrology, the Palmer Drought Severity Index (PDSI). The PDSI is based on a hydrological model and is a cumulative measure that takes account of...
