Book excerpt: Excerpt from Review of Forage Losses Caused by Rangeland Grasshoppers According to Cowan damage to rangeland varies geographically and from year to year. It is governed largely by the grasshopper species com plex, the vegetation complex, the numbers of grasshoppers, and the weather. Three types of damage are possible: (1) Removal of forage in direct competition with livestock, (2) permanent damage to the plants due to continued feeding by grasshop pers beyond accepted percent use factors, and (3) Rangeland Insect Laboratory, Agricultural Research Serv ice, Montana State University, Bozeman, Mont.

Book Synopsis Rangeland Systems by : David D. Briske
Download or read book Rangeland Systems written by David D. Briske and published by Springer. This book was released on 2017-04-12 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.
Book Synopsis Biological Control: Measures of Success by : G. Gurr

Available in PDF, EPUB and Kindle. Book excerpt: As well as examining successful biological control programmes this book analyses why the majority of attempts fail. Off-target and other negative effects of biological control are also dealt with. Chapters contributed by leading international researchers and practitioners in all areas of biological control afford the book a breadth of coverage and depth of analysis not possible with a single author volume. Combined with the use of other experts to review chapters and editorial oversight to ensure thematic integrity of the volume, this book provides the most authoritative analysis of biological control published. Key aspects addressed include how success may be measured, how successful biological control has been to date and how may it be made more successful in the future. With extensive use of contemporary examples, photographs, figures and tables this book will be invaluable to advanced undergraduate and postgraduate students as well as being a `must' for all involved in making biological control successful.

Book Synopsis New Strategies in Locust Control by : S. Krall
Download or read book New Strategies in Locust Control written by S. Krall and published by Birkhäuser. This book was released on 2012-12-06 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.

Book Synopsis Rewilding European Landscapes by : Henrique M. Pereira
Download or read book Rewilding European Landscapes written by Henrique M. Pereira and published by Springer. This book was released on 2015-05-04 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some European lands have been progressively alleviated of human pressures, particularly traditional agriculture in remote areas. This book proposes that this land abandonment can be seen as an opportunity to restore natural ecosystems via rewilding. We define rewilding as the passive management of ecological successions having in mind the long-term goal of restoring natural ecosystem processes. The book aims at introducing the concept of rewilding to scientists, students and practitioners. The first part presents the theory of rewilding in the European context. The second part of the book directly addresses the link between rewilding, biodiversity, and habitats. The third and last part is dedicated to practical aspects of the implementation of rewilding as a land management option. We believe that this book will both set the basis for future research on rewilding and help practitioners think about how rewilding can take place in areas under their management.
Book Synopsis Eurasian Steppes. Ecological Problems and Livelihoods in a Changing World by : Marinus J.A. Werger
Download or read book Eurasian Steppes. Ecological Problems and Livelihoods in a Changing World written by Marinus J.A. Werger and published by Springer Science & Business Media. This book was released on 2012-06-14 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steppes form one of the largest biomes. Drastic changes in steppe ecology, land use and livelihoods came with the emergence, and again with the collapse, of communist states. Excessive ploughing and vast influx of people into the steppe zone led to a strong decline in nomadic pastoralism in the Soviet Union and China and in severely degraded steppe ecosystems. In Mongolia nomadic pastoralism persisted, but steppes degraded because of strongly increased livestock loads. After the Soviet collapse steppes regenerated on huge tracts of fallow land. Presently, new, restorative steppe land management schemes are applied. On top of all these changes come strong effects of climate change in the northern part of the steppe zone. This book gives an up-to-date overview of changes in ecology, climate and use of the entire Eurasian steppe area and their effects on livelihoods of steppe people. It integrates knowledge that so far was available only in a spectrum of locally used languages.
Download or read book Coping with Climate Change written by and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic resources for food and agriculture play a crucial role in food security, nutrition and livelihoods and in the provision of environmental services. They are key components of sustainability, resilience and adaptability in production systems. They underpin the ability of crops, livestock, aquatic organisms and forest trees to withstand a range of harsh conditions. Climate change poses new challenges to the management of the world's genetic resources for food and agriculture, but it also underlines their importance. At the request of the Commission on Genetic Resources for Food and Agriculture, FAO prepared thematic studies on the interactions between climate change and plant, animal, forest, aquatic, invertebrate and micro-organism genetic resources. This publication summarizes the results of these studies.
