La restauration des grands migrateurs rhodaniens et méditerranéens : contribution des sciences biologiques et sociales
2001
In order to warrant the sustainability of migratory fish in the Rhone and Mediterranean area, two policies have been developed. The first one, concerning shads, has already made possible to pass the first three locks and several weirs on the tributaries. Symmetrically, a concerted restoration plan has been elaborated for the restoration of eels populations. Its main objective consists of making resettlement of their habitat, fully performing their ecologically regulating role, and satisfying social and economic requirements. The role of scientists appears to be major, for diagnosing and assessing the ecological justification of the actions, their technical viability (esp. of stocking), and …
A global view on econometrics of prevention in connection with the Inondabilité method
1998
Vulnerability, as one of the two components of flood risk, at the level of each land-owner or -user in a flood-plain, is defined as an acceptable limit, expressed in terms of return period. In order to obtain a maximal fiability in vulnerability mapping and, then, in this of synthetic risk, this maximal risk has to be expressed in an objective way, from a global appreciation of his objectives, potentialities and restraints. From there, one can propose a methodology for making this limit explicit in relation with the submersion parameters, in order to apply it mainly to agricultural zones in a flood plain. Finally, other potentialities of economic evaluation for designing of preventive proje…
Economic valuation of the maximum acceptable risk
2000
Vulnerability plays a critical role in implementing the Inondabilité method. Its quantification is based on the concept of maximum acceptable risk, to be applied to each of the land uses in the floodplain. To define such a limit of risk on an objective basis requires to identify a level of maximum acceptable loss and to complete a micro-economic analysis of the activity as a whole, including its objectives, resources, restraints and results, at a more or less high degree of detail. More attention is devoted to the technico-economic background, the financial capacity and the system of information-perception-adaptation of the agent, which are the main factors influencing the level of maximum …
