Secteur minier, décentralisation et pouvoir étatique au Sénégal : un modèle de gouvernance? Cet article analyse l'économie politique du secteur minier et du processus de décentralisation au Sénégal. Dans les deux cas, l'État a confié sa responsabilité en matière de développement aux acteurs locaux, sans leur transférer ni les ressources matérielles ni l'autorité nécessaires. Cette contradiction se résout dans la mise en place de connexions entre espaces locaux et globaux, qui transforment radicalement le rapport de l'État à sa population. Ces reconfigurations du pouvoir d'État sont intimement liées aux changements idéologiques et institutionnels associés à la globalisation néolibérale.

"This book reconstructs climatic changes in deserts and their margins at a variety of scales in space and time. It draws upon evidence from land and sea, including desert dunes, wind-blown dust, river and lake sediments, glacial moraines, plant and animal fossils, isotope geochemistry, speleothems, soils, and prehistoric archaeology. The book summarises the Cenozoic evolution of the major deserts of the Americas, Eurasia, Africa and Australia and the causes of historic floods and droughts. The book then considers the causes and consequences of desertification and proposes four key conditions for achieving ecologically sustainable use of natural resources in arid and semi-arid areas. Climate Change in Deserts is an invaluable reference for researchers and advanced students interested in the climate and geomorphology of deserts: geographers, geologists, ecologists, archaeologists, soil scientists, hydrologists, climatologists and natural resource managers."--

AbstractThere is a broad consensus that state capacity is central to economic and institutional development. But while the concept originated as a tool for macro-historical and comparative analysis, its success has led the term 'capacity' to become a default metaphor for discussing the quality of government bureaucracies. This paper discusses the limitations to conceiving of narrower questions of bureaucratic performance and policy implementation through the lens of the broad, aggregate concept of capacity. Whereas capacity refers to bureaucracies' hypothetical potential, this usually differs from their actual actions due to internal information and incentive problems created by bureaucracies' collective nature, and the constraints and uncertainty imposed by their multiple political principals. Capacity is a convenient shorthand term and is appropriate for some purposes, but it achieves this convenience by abstracting away from the mechanisms that determine bureaucratic performance and policy implementation. To advance the study of bureaucratic quality, researchers should seek to understand the implications of bureaucracies' collective nature, engage with contextual specificity and contingency in policy implementation, and focus measurement and reform efforts more towards actual performance than hypothetical capacity.
