Consumer preferences, aquaculture technology and the sustainability of fisheries

Regnier, Esther; Schubert, Katheline - HAL - 2013

This article analyzes the impact of aquaculture on wild fish stocks and on fish consumption, taking into account its … dependence on reduction fisheries for the feeding of the farmed species and consumet preferences. The model includes the demand … side and three sectors : and edible fish fishery and a reduction fishery, both in open access, and an aquaculture sector …

Robust viable management of a harvested ecosystem model

Regnier, Esther; Lara, Michel De - HAL - 2013

The Word Summit on Sustainable Development (Johannesburg, 2002) encouraged the application of the ecosystem approach by 2010. In this perspective, we propose a theoretical management framework that deals jointly with i) ecosystem dynamics, ii) conflicting issues of production and preservation...

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...
