This book was released on 2008 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: En Afrique de l'Ouest, une série de facteurs contribue à la baisse de la productivité agricole : la dégradation de l'environnement, la forte croissance démographique, les attaques acridiennes, la performance insuffisante des économies. De nombreux pays enregistrent d'énormes déficits alimentaires. Une telle situation ne peut être améliorée qu'à partir de l'adoption de nouvelles technologies visant à l'obtention de meilleurs rendements. Dans cet ouvrage organisé en quatre chapitres, les auteurs se penchent sur les déterminants d'une meilleure productivité agricole. L'accent est surtout mis sur les aléas climatiques de ces dernières décennies, marquées par de fortes irrégularités saisonnières et une baisse régulière de la pluviométrie. Aux aléas climatiques s'ajoute le problème de la fertilité des sols caractérisé le plus souvent par un faible taux de matières organiques : carence en phosphore et en azote, complexe absorbant insuffisant, petite capacité de rétention en eau, etc. Enfin, dans les régions à forte densité de population ( exemples du Ghana et du Togo ), le taux de croissance démographique élevé agit négativement sur le potentiel foncier, caractérisé par la dégradation des ressources naturelles. Les auteurs exposent ici les réalités de ces facteurs déterminants pour la sécurité alimentaire, afin de permettre aux décideurs de mieux les intégrer à leur politique de développement du secteur agricole.

Download or read book Research on Agricultural Systems written by Jean Philippe Colin and published by Nova Biomedical Books. This book was released on 2000 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to provide an overview of research on agricultural systems that is both broad and selective. The focus is broad, by covering approaches used in a number of disciplines, as well as in multidisciplinary studies, and by defining agricultural systems to include cropping systems, fanning systems, agricultural household systems, and agricultural systems at higher levels such as the agrarian system. The focus is selective by emphasizing key methods and ongoing debates, rather than attempting a comprehensive review of literature. Most previous reviews of research on agricultural systems have concentrated on a particular approach, eg farming systems research (FSR), including comparisons of anglophone and francophone variants of FSR, or on research conducted in specific geographical settings.

Download or read book The Routledge Handbook of Political Ecology written by Tom Perreault and published by Routledge. This book was released on 2015-06-12 with total page 669 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Routledge Handbook of Political Ecology presents a comprehensive and authoritative examination of the rapidly growing field of political ecology. Located at the intersection of geography, anthropology, sociology, and environmental history, political ecology is one of the most vibrant and conceptually diverse fields of inquiry into nature-society relations within the social sciences. The Handbook serves as an essential guide to this rapidly evolving intellectual landscape. With contributions from over 50 leading authors, the Handbook presents a systematic overview of political ecology’s origins, practices and core concerns, and aims to advance both ongoing and emerging debates. While there are numerous edited volumes, textbooks, and monographs under the heading ‘political ecology,’ these have tended to be relatively narrow in scope, either as collections of empirically based (mostly case study) research on a given theme, or broad overviews of the field aimed at undergraduate audiences. The Routledge Handbook of Political Ecology is the first systematic, comprehensive overview of the field. With authors from North and South America, Europe, Australia and elsewhere, the Handbook of Political Ecology provides a state of the art examination of political ecology; addresses ongoing and emerging debates in this rapidly evolving field; and charts new agendas for research, policy, and activism. The Routledge Handbook of Political Ecology introduces political ecology as an interdisciplinary academic field. By presenting a ‘state of the art’ examination of the field, it will serve as an invaluable resource for students and scholars. It not only critically reviews the key debates in the field, but develops them. The Handbook will serve as an excellent resource for graduate and advanced undergraduate teaching, and is a key reference text for geographers, anthropologists, sociologists, environmental historians, and others working in and around political ecology.

Download or read book Cocoa Cycles written by François Ruf and published by Elsevier. This book was released on 1995-06-30 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cyclical boom-to-recession nature of the economics of cocoa supply is a major problem for the international cocoa industry - and especially for countries whose economies depend on cocoa exports. Only through an understanding of the dynamics of cocoa cycles can policy decisions be made through the various phases of supply cycles. Based on a major international cocoa conference, this book presents seventeen edited papers from leading experts, making a major contribution to that understanding. It explains the powerful economic, social and political factors which impact on the cocoa economy. It shows the laws of cocoa supply are closely linked to environmental, ecological and institutional factors.

Download or read book Comparative Agriculture written by Hubert Cochet and published by Springer. This book was released on 2015-04-20 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the first section dedicated to theoretical thoughts on comparative agriculture, Hubert Cochet introduces the notion of “agricultural development”, the very subject of comparative agriculture, with a restored endogenous dimension. He then describes how this approach was slowly consolidated, around the concept of agrarian system in particular. The comparison of agricultural transformations in time and space highlights the importance of the comparatist approach to production processes, their trajectories and differentiation on a worldwide scale. The second section which focuses on the methods and expertise of comparative agriculture, tackles the issues of landscape analysis, field surveys and the historical approach underlying comparative agriculture. It sums up the economic tools mobilised as well as the evaluation perspectives opened up by comparative agriculture.
