Drip Irrigation for Agriculture / ,Jean-Philippe Venot (2017)

Public ISBD Titre : Drip Irrigation for Agriculture : Untold Stories of Efficiency, Innovation and Development Type de document : texte imprimé Auteurs : ,Jean-Philippe Venot, Auteur ; Kuper Marcel, Auteur ; Zwarteveen Margreet, Auteur Editeur : London : Routledge Année de publication : 2017 Importance : 1 fichier PDF ISBN/ISSN/EAN : 978-1-134-98975-1 Note générale : Index Langues : Anglais (eng) Mots-clés : Microirrigation Index. décimale : 631.147 Biotechnologie. Agriculture biologique (alternative, écologique, utilisant des technologies propres) Résumé : Initially associated with hi-tech irrigated agriculture, drip irrigation is now being used by a much wider range of farmers in emerging and developing countries. This book documents the enthusiasm, spread and use of drip irrigation systems by smallholders but also some disappointments and disillusion faced in the global South. It explores and explains under which conditions it works, for whom and with what effects. The book deals with drip irrigation'behind the scenes', showcasing what largely remain'untold stories'.Most research on drip irrigation use plot-level studies to demonstrate the technology's ability to save water or improve efficiencies and use a narrow and rather prescriptive engineering or economic language. They tend to be grounded in a firm belief in the technology and focus on the identification of ways to improve or better realize its potential. The technology also figures prominently in poverty alleviation or agricultural modernization narratives, figuring as a tool to help smallholders become more innovative, entrepreneurial and business minded. Instead of focusing on its potential, this book looks at drip irrigation-in-use, making sense of what it does from the perspectives of the farmers who use it, and of the development workers and agencies, policymakers, private companies, local craftsmen, engineers, extension agents or researchers who engage with it for a diversity of reasons and to realize a multiplicity of objectives. While anchored in a sound engineering understanding of the design and operating principles of the technology, the book extends the analysis beyond engineering and hydraulics to understand drip irrigation as a sociotechnical phenomenon that not only changes the way water is supplied to crops but also transforms agricultural farming systems and even how society is organized. The book provides field evidence from a diversity of interdisciplinary case studies in sub-Saharan Africa, the Mediterranean, Latin America, and South Asia, thus revealing some of the untold stories of drip irrigation Drip Irrigation for Agriculture : Untold Stories of Efficiency, Innovation and Development [texte imprimé] / ,Jean-Philippe Venot, Auteur ; Kuper Marcel, Auteur ; Zwarteveen Margreet, Auteur . - London : Routledge, 2017 . - 1 fichier PDF.

Editeur : London : Routledge Année de publication : 2022 Importance : XIII,408 p. Présentation : ill. Format : 24 cm. ISBN/ISSN/EAN : 978-0-367-43123-5 Note générale : Index Langues : Anglais (eng) Mots-clés : Machine drawings Technical drawing Descriptive geometry Computer aided design Index. décimale : 744 Dessin technique Résumé : This introduction to descriptive geometry and contemporary drafting guides the student through the essential principles to create engineering drawings that comply with international standards of technical product specification. This heavily updated new edition now applies to CAD as well as conventional drawing. Extensive new coverage is given of: • International drafting conventions • Methods of spatial visualisation such as multi-view projection • Types of views • Dimensioning • Dimensional and geometric tolerancing • Representation of workpiece and machine elements • Assembly drawings Comprehensible illustrations and clear explanations help the reader master drafting and layout concepts for creating professional engineering drawings. The book provides a large number of exercises for each main topic. This edition covers updated material and reflects the latest ISO standards. It is ideal for undergraduates in engineering or product design, students of vocational courses in engineering communication and technology students covering the transition of product specification from design to production.

Phyto and microbial remediation of heavy metals and radionuclides in the environment / Rym Salah-Tazdait (2022)

Public ISBD Titre : Phyto and microbial remediation of heavy metals and radionuclides in the environment : an eco-friendly solution for detoxifying soils Type de document : texte imprimé Auteurs : Rym Salah-Tazdait, Auteur ; Djaber Tazdait, Auteur Editeur : London : Routledge Année de publication : 2022 Importance : XII, 108 p. Présentation : ill. Format : 22 cm ISBN/ISSN/EAN : 978-1-03-225305-3 Note générale : Bibliogr. en fins de chapitres. Index Langues : Anglais (eng) Mots-clés : Bioscience soils -- detoxifying Radioactive pollution Environmental engineering Bioremediation Index. décimale : 614.7 Hygiène de l'air du sol et de l'eau. Pollution et contrôle de la pollution. Résumé : This book examines the role that bioremediation can play in the detoxification of soil, water, and air to improve environmental and human health, with a specific focus on heavy metals and radionuclides. Environmental pollution, whether by natural or human causes, with industrial activities being a key player, is a challenge facing all nations across the world. While treatment has typically required the use of expensive technology, one promising solution is the use of phytoremediation, in which plants act by metabolizing or sequestering pollutants. This eco-friendly solution is a good alternative to the standard methods of soil and water treatments. This book provides not only the basic definitions and classification of technologies used for contaminant remediation but also the most recent studies dealing with the selection of new promising microbial stains and plant varieties involved in the treatment of radioactive and heavy metal contaminants. It provides a detailed description of the biochemical mechanisms and genes involved in the bioremediation of radionuclides and heavy metals, offering a clear insight for academics and practitioners interested in in vitro and in situ biological treatment. This book will be of great value to students and scholars interested in environmental pollution and environmental health from across a range of different disciplines, including environmental microbiology and chemistry, ecology and environmental science, biological and environmental engineering and biotechnology. Note de contenu : Au sommaire : 1. General Outline of Bioremediation 2. Radionuclides and Heavy Metals 3. Mechanisms of Phytoremediation and Microbial Remediation of Radionuclides 4. Mechanisms of Phytoremediation and Microbial Remediation of Heavy Metals 5. Approaches for Increasing Bioremediation Capabilities of Plants and Microorganisms towards Heavy Metals and Radionuclides 6.
