Download or read book Farmer First Revisited written by Ian Scoones and published by Practical Action Publishing. This book was released on 2009 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is an urgent global priority and farmers find themselves in the front line of some of the world's most pressing issues- climate change, globalization and food security. Twenty years ago, the Farmer First workshop held at the Institute of Development Studies, University of Sussex, UK, launched a movement to encourage farmer participation in agricultural research and development (R & D), responding to farmers' needs in complex, diverse, risk-prone environments, and promoting sustainable livelihoods and agriculture. Since that time, methodological, institutional and policy experiments have unfolded around the world. Farmer First Revisited returns to the debates about farmer participation in agricultural R & D and looks to the future.The book presents a range of experiences that highlight the importance of going beyond a focus on the farm to a wider innovation system, including market interactions as well as the wider institutional and policy environment. If, however, farmers are really to be put first, a politics of demand is required in order to shape the direction of these innovative systems.

Download or read book Enhancing Agricultural Innovation written by World Bank and published by World Bank Publications. This book was released on 2006-11-03 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: An innovation system can be defined as a network of organizations, enterprises, and individuals demanding and supplying knowledge and bringing it into a social and economic use. This book's primary aim, therefore, is to focus on the largely unexplored operational aspects of the innvoation systems concept and to explore its potential for agriculture. 'Enhancing Agricultural Innovation' evaluates real-world innovation systems and assesses the usefulness of the concept in guiding investments to support knowledge-intensive, sustainable agricultural development. A typology of innovation systems is developed; strategies to guide investments for strengthening innovation capacity are drawn up; and concrete interventions options defined. In its conclusions, the book emphasizes the importance of mechanisms for collaboration and interaction. Intermediary organizations, innovation councils, farmer organizations, and other means to strengthen collaboration are central to creating the exchange of knowledge and perspectives that will convert knowledge into valuable new social and economic products and services.

Download or read book Beyond Farmer First written by Ian Scoones and published by Practical Action. This book was released on 1994 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to reveal how agricultural research and extension, far from being discrete, rational acts, are in fact part of a process of coming to terms with conflicting interests and viewpoints. By going beyond Farmer First, this theoretically informed perspective describes agricultural development as what it is: a highly ideological and political process. As Robert Chambers notes in his foreword, the concerns of Farmer First with performance and of Beyond Farmer First with process, indicate that a radical rethinking of knowledge, power and agricultural science is well under way.

Elle est indispensable à la sécurité alimentaire mondiale sujette au défi démographique. Pour autant, les enjeux d’une agriculture irriguée durable sont multiples pour répondre aux nécessités actuelles et futures. L’ouvrage apporte des éclairages sur ces différents défis, à partir de retours d’expériences issus de plusieurs décennies d’actions de développement international de l’agriculture irriguée.

Download or read book tude de l atomisation d un jet d eau haute vitesse written by Christophe Stevenin and published by Presses Academiques Francophones. This book was released on 2013 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans le contexte actuel, l'accroissement des tensions liées à l'utilisation de la ressource en eau impose une meilleure gestion de cette ressource pour la poursuite d'une croissance économique durable. Cette problématique liée à la ressource en eau s'inscrit également dans des préoccupations sociales et environnementales importantes. En Europe, l'irrigation par aspersion représente une large part de la consommation en eau. Or l'irrigation des champs par aspersion est parfois mal adaptée et engendre de fortes pertes, dues à l'évaporation ou à la dispersion due au vent. Ces apports nécessitent d'être optimisés, ce qui passe par une meilleure maîtrise de la taille et de la dispersion des gouttes produites durant l'aspersion. L'objectif principal de cette thèse est la caractérisation des gouttes produites pendant l'atomisation d'un jet d'eau utilisé en irrigation par aspersion et la modélisation de l'atomisation de ce jet. Une technique d'ombroscopie est mise en place pour analyser le coeur liquide et pour caractériser la population de gouttes d'eau produites en terme de tailles et de vitesses moyennes et fluctuantes de la phase liquide. Une attention particulière a été portée sur la calibration de la technique et sur l'estimation des tailles de gouttes produites durant l'atomisation. L'approche employée pour la modélisation de l'atomisation repose sur une description eulérienne de l'écoulement diphasique, où celui-ci est représenté comme un écoulement turbulent d'un seul fluide dont la masse volumique varie selon la composition du mélange diphasique, entre la masse volumique du gaz et celle du liquide. La dispersion du liquide dans son environnement gazeux est prise en compte par la résolution d'une équation de transport de la fraction massique moyenne du liquide. De plus, une équation de transport de la densité moyenne d'interface liquide/ gaz permet de modéliser les phénomènes de fragmentation et de coalescence des gouttes et in fine d'estimer la taille des gouttes
