Essays on development and biodiversity conservation in Sub-Saharan Africa / Essais sur le développement et la conservation de la biodiversité en Afrique sub-saharienneAmin, Ariane Manuela 03 December 2014 (has links)
La présente thèse est composée d’un ensemble de travaux de recherche en économie appliquée qui s’inscrivent dans le champ contemporain de l’économie de la biodiversité. La thèse s’intéresse spécifiquement aux liens entre développement économique, bien-être local et conservation de la biodiversité avec comme zone d’étude l’Afrique subsaharienne. Un chapitre introductif présente les questions de recherche débattues dans cette thèse et situe notre contribution dans la littérature.Le reste de la thèse est composé de deux parties regroupées en études macroéconomiques et en études de terrain. La partie 1 (composé du chapitre 2 et du chapitre 3) aborde le lien biodiversité-développement sous un angle macroéconomique en considérant les interactions spatiales entre pays. Le chapitre 2 examine l’impact du développement en Afrique Subsaharienne sur la biodiversité mesuré à partir d’indicateurs récents sur les espèces menacés. Le chapitre 3 s’intéresse aux mécanismes qui soutiennent les politiques publiques de conservation en Afrique Subsaharienne et teste l’effet du tourisme, de l’aide environnementale et des effets transfrontaliers sur l’effort de conservation. La partie 2 (composé du chapitre 4 et du chapitre 5) présente deux études de cas en Côte d’Ivoire. Le chapitre 4 évalue monétairement les coûts et les bénéfices de la conservation pour les populations locales. Le chapitre 5 examine les préférences des populations pour la conservation et identifie les facteurs clés qui déterminent ces préférences locales. Le chapitre 6 fait une synthèse des résultats en tire les implications en termes de recommandations de politiques et présente de potentielles extensions de la thèse. / This thesis is composed of a set of research in applied economics that enroll in the contemporary field of economics of biodiversity. The thesis focuses specifically on the links between economic development, local welfare and biodiversity conservation in sub-Saharan Africa region. An introductory chapter presents the subject of the thesis as well as the research field and situates our contribution.The rest of the thesis is composed of two parts divided into macroeconomic studies and case studies. Part 1 (composed of chapter 2 and chapter 3) addresses the link biodiversity and development under a macroeconomic perspective by taking into account spatial interactions between countries. In chapter 2, we examine the impact of development in sub-Saharan Africa on biodiversity using recent indicators on threatened species. In chapter 3, we focus on the mechanisms that support public conservation policies in Sub-Saharan Africa and tested the effect of tourism, environmental aid and spillover effects on conservation effort. Part 2 (composed of chapter 4 and chapter 5) presents two case studies in Ivory Coast. Chapter 4 presents a cost benefit analysis using contingent valuation and market price method. It evaluates the costs and benefits of conservation for local populations. In chapter 5 we examine people's preferences for conservation and identify key factors that determine local preferences. In the last chapter we draw implications of results and present potential extensions of this thesis.

Re-establishing an Ecological Discourse in the Debate over the Value of Ecosystems and BiodiversitySpash, Clive L., Aslaksen, Iulie January 2012 (has links) (PDF)
The approach of conceptualizing biodiversity and ecosystems as goods and services to be
represented by monetary values in policy is being championed not just by economists, but
also by ecologists and conservation biologists. This new environmental pragmatism is now
being pushed forward internationally under the guise of hardwiring biodiversity and
ecosystems services into finance. This conflicts with the realisation that biodiversity and
ecosystems have multiple incommensurable values. The current trend is to narrowly define a
set of instrumental aspects of ecosystems and biodiversity to be associated with ad hoc
money numbers. We argue that ecosystem science has more to offer the policy debate than
pseudo-economic numbers based on assumptions that do not reflect ecological or social
complexity. Re-establishing the ecological discourse in biodiversity policy implies a crucial
role for biophysical indicators as policy targets e.g., the Nature Index for Norway. Yet there
is a recognisable need to go beyond the traditional ecological approach to create a social
ecological economic discourse. This requires reviving and relating to a range of alternative
ecologically informed discourses (e.g. intrinsic values, deep ecology, ecofeminism) in order
to transform the increasingly dominant and destructive relationship of humans separated from
and domineering over Nature. (author's abstract) / Series: SRE - Discussion Papers
