Book Description
Nous proposons de montrer dans quelle mesure l' introduction d' aléas affecte certains modèles de gestion de ressources naturelles. Les résultats obtenus dépendent principalement du type de ressource considéré et des variables sur lesquelles porte l' incertitude. Le chapitre 1 établit la règle optimale d' exploitation d' une ressource renouvelable qui présente des valeurs d' aménités et dont la dynamique est continûment perturbée par des fluctuations stochastiques. Des deux effets des aménités et de l' incertitude qui agissent de façon opposée sur les prélèvements de ressource, nous montrons que le premier l' emporte si et seulement si la taille des fluctuations n' est pas trop importante. Le chapitre 2 analyse la gestion optimale d' une ressource renouvelable confrontée à un risque permanent de catastrophes naturelles. Le chapitre 3 introduit la possibilité de découvrir à une date aléatoire, un nouveau gisement de ressource et étudie l' effet de cette découverte sur l' équilibre d' un marché de ressource non renouvelable soumis à la concurrence d' une technologie "backstop". Enfin, l' objet du chapitre 4 est de montrer comment la contrainte d' épuisement d' une ressource non renouvelable sur laquelle risquerait de buter à terme la volonté de maintien d' un certain niveau de consommation, peut être contournée grâce à un effort permanent d' exploration et pourquoi l' économie devrait se placer sur un sentier de croissance durable dès lors que l' impatience de la société est susceptible d' être compensée par les effets positifs des découvertes de ressource.

Book Description
Aujourd'hui, la quête d'un développement soutenable est au cœur des préoccupations. Ce livre actualisé présente les concepts et les théories économiques traitant de la gestion de ces ressources naturelles. Il veut ainsi contribuer à mieux faire comprendre les questions cruciales posées par notre mode de développement. La pêche va-t-elle disparaître ? Détruisons-nous les forêts ? Aurons-nous du pétrole dans vingt ans ? Va-t-on répondre aux besoins en eau des habitants de la planète à la fin du siècle ? Que devient le climat ? Ces questions révèlent des craintes de plus en plus partagées et mettent en cause notre mode de développement. Celui-ci repose, d'une part, sur l'utilisation croissante de sources d'énergie primaire (pétrole, gaz, charbon...) limitées, donc épuisables, et, d'autre part, sur des ressources qui, il y a moins de cent ans, semblaient inépuisables (air) ou capables de se renouveler (eau, forêts, poissons). Aujourd'hui, la quête d'un développement soutenable est au cœur des préoccupations. Ce livre actualisé présente les concepts et les théories économiques traitant de la gestion de ces ressources naturelles. Il veut ainsi contribuer à mieux faire comprendre les questions cruciales posées par notre mode de développement.

Book Description
Aiming to support the development of a framework for the analysis of risk in project design and economic analysis, this handbook outlines technical approaches to modeling risk. Also summarized is the nature and practice of sensitivity analysis in dealing with uncertain outcomes as well as the principles to consider in typical risk analysis situations sector by sector. Case studies are included to demonstrate the application of quantitative risk analysis using actual Asian Development Bank projects to help improve project design and quality. Handbook users will learn to identify factors that are the key determinants of project outcomes, determine the likelihood of an individual project's returns being unacceptable, and design measures to mitigate the risks arising from the identified key factors.

Book Description
In this brillant meditation on conceptions of history, Le Goff traces the evolution of the historian's craft. Examining real and imagined oppositions between past and present, ancient and modern, oral and written history, History and Memory reveals the strands of continuity that have characterized historiography from ancient Mesopotamia to modern Europe.

Book Description
"The applied research indicates that, to improve awareness, park education programs should be targeted specifically to the user groups primarily through outreach programs. Further, the Park's management programs should be highlighted, particularly the beneficial, tangible products and services (benefits) the Park provides to each user group... The closer the tie between reef conditions and business earnings, the greater the users' support for reef conservation." Coral reefs are sometimes referred to as "canaries of the sea" because of their early warning ability to show near-shore oceanic stress. Because of their biological diversity, they are also called "rainforests of the sea." Coral reefs are vital to the well being of millions of people. Coral reef managers and government officials trying to save their valuable national resources have turned to research on coral reefs for help. The research presented in this publication merits a great deal of notice because the output is useful for decision support and training tools in integrated coastal zone management (ICZM). The work on cost-effectiveness analysis has developed integrated economic and ecological models, relying extensively on fuzzy logic procedures to model impacts and effects of interventions within the reef environment. By contrast, the marine system valuation work provides economic valuations of coral reefs, demonstrating the use of different modeling methods and treating key policy issues within this context. This publication will interest coastal zone experts and managers worldwide
