This book presents some examples of the richness and variety of contemporary research on rural-urban interactions by francophone researchers. Case studies are drawn from Burkina Faso, Ctte d'Ivoire, Congo, Benin, Senegal and Togo.

En pleine congruence avec l’ambition du Groupe Européen pour l’Administration Publique d’encourager les échanges interculturels, ce livre constitue une entreprise originale, mi-anglophone mi-francophone. Cet ouvrage issu du Congrès du GEAP 2010 a pour objet de combler un déplorable fossé et de donner une visibilité internationale au « cas français ». Dès lors ce livre, en 18 chapitres rédigés en français par une équipe interdisciplinaire (politistes, sociologues, historiens, socio-historiens, juristes) avec plus de 150 pages en anglais et une vaste bibliographie unifiée, entend offrir à tous les spécialistes de l’administration publique de par le monde un point d’accès unique au plus récent état des savoirs sur l’administration en France – ce pays où le mot État s’écrit avec un E majuscule. ============================================ In full compliance with the ambition of the European Group for Public Administration to encourage cross-cultural exchanges, this book is a genuinely original undertaking. It is a hybrid Anglophone-Francophone product. This book from EGPA 2010 Conference purpose to bridge a regrettable gap and to give international visibility to the “French case”.

This book has been developed from a workshop on Technological change in agriculture and tropical deforestation organised by the Center for International Forestry Research and held in Costa Rica in March, 1999. It explores how intensification of agriculture affects tropical deforestation using case studies from different geographical regions, using different agricultural products and technologies and in differing demographic situations and market conditions. Guidance is also given on future agricultural research and extension efforts.

Hierarchy is a form of organisation of complex systems that rely on or produce a strong differentiation in capacity (power and size) between the parts of the system. It is frequently observed within the natural living world as well as in social institutions. According to the authors, hierarchy results from random processes, follows an intentional design, or is the result of the organisation which ensures an optimal circulation of energy for information. This book reviews ancient and modern representations and explanations of hierarchies, and compares their relevance in a variety of fields, such as language, societies, cities, and living species. It throws light on concepts and models such as scaling laws, fractals and self-organisation that are fundamental in the dynamics and morphology of complex systems. At a time when networks are celebrated for their efficiency, flexibility and better social acceptance, much can be learned about the persistent universality and adaptability of hierarchies, and from the analogies and differences between biological and social organisation and processes. This book addresses a wide audience of biologists and social scientists, as well as managers and executives in a variety of institutions.
