The Untold Stories of African Agriculture

Book Description
This landmark volume presents the results of a comprehensive and coherent in-depth assessment of Ethiopian agriculture and draws lessons from it to generate actionable recommendations that will inform policy decisions and priority setting for agricultural transformation across Africa. Policy makers in Africa are faced with the challenges of ensuring food and nutrition security and the economic wellbeing of their rapidly growing populations while at the same time maintaining the integrity of their natural resource base. Between 2000 and 2021, 74% of the growth in overall crop production on the continent was derived from increases in land area expansion, while increases in yield contributed only 26% of the growth. This unchecked expansion of land use puts the sustainability of the natural resource base under severe pressure. This book draws on a unique set of case studies from Ethiopia described and told from a truly African perspective.
Fundamentals of Weed Science
Author: Robert L ZimdahlPublisher: Academic Press
ISBN: 0123978181
Category : Science
Languages : en
Pages : 671
Book Description
This book addresses herbicides and their use as an important aspect of modern weed management and strives to place them in an ecological framework. Many weed scientists believe agriculture is a continuing struggle with weeds--without good weed control, good and profitable agriculture is impossible. Each agricultural discipline sees itself as central to agriculture's success and continued progress, and weed science is no exception. While not denying the importance of weed management to successful agriculture, this book places it in a larger ecological context. The roles of culture, economics, and politics in weed management are also discussed, enabling scientists and students to understand the larger effects on society. - Information on New herbicides included, along with the old herbicides that are important for understanding the history - New section on weed resistance to herbicides and genetic engineering - New information on invasive plants - Expanded chapters on Biological Control, Pesticide Legislation and Regulation, Weed Management Systems, and more - Instructor resources can be found at http://textbooks.elsevier.com/web/Login.aspx, and it is password protected.

Book Description
Fundamentals of Weed Science provides an introduction to the basic principles of weed science for undergraduate courses. It discusses several aspects of weed biology and control, and traces the history of herbicide development. The book begins with an introduction to weeds, covering their definition, characteristics, harmful aspects, and the cost of weed control. This is followed chapters on weed classification, the uses of weeds, weed biology, weed ecology, allelopathy, the significance of plant competition, weed management and control methods, and biological weed control. Later chapters deal with herbicidesthe most important weed control tools and the ones with the greatest potential for untoward effects. Students of weed science must understand herbicides and the factors governing their use as well as the potential for misuse. These chapters discuss chemical weed control, the properties and uses of herbicides, factors affecting herbicide performance, herbicide application, herbicide formulation, ecological impact of herbicides, pesticide registration and legislation, weed management systems, and the future of weed science.
