Grassland Productivity and Ecosystem Services

Grassland ecosystems are deeply affected by human activities and need appropriate management to optimise trade-offs between ecosystem functions and services. Until now they have mainly been analysed as agro-ecosystems for animal production but this book looks beyond the role of grassland as a feeding ground, and evaluates other important processes such as carbon sequestration in soils, greenhouse gas regulation and biodiversity protection. This authoritative volume expertly highlights the need for an immediate balance between agriculture and ecological management for sustainability in the futu.

Agroecosystem Diversity

Agro-Ecosystem Diversity: Impact on Food Security and Environmental Quality presents cutting-edge exploration of developing novel farming systems and introduces landscape ecology to agronomy. It encompasses the broad range of links between agricultural development and ecological impact and how to limit the potential negative results. Presented in seven sections, each focusing on a specific challenge to sustaining diversity, the book provides insights toward the argument that by re-introducing diversity, it should be possible to maintain a high level of productivity of agro-ecosystems while also maintaining and/or restoring a satisfactory level of environment quality and biodiversity. Demonstrates that diversified agro-ecosystems can be intensified with environmental quality preserved, restored and enhanced Includes analysis of economic constraints leading to specialization of farms and regions and the social locking forces resisting to diversification of agro-ecosystems Presents a global vision of world agriculture and the tradeoff between a necessary increase in food production and restoring environment quality

Grazing behavior and forage selectivity of cattle and sheep grazing alone or together on swards differing in plant species diversity

Grassland composition and animal species may modify the grazing efficiency and ingestive behavior at pasture. However, precise knowledge on potential interactions between sward diversity and co-grazing is not available. Thus, a trial was conducted to evaluate the behavior patterns and forage selectivity of cattle and sheep grazing alone or together on grass swards differing in botanical composition. The experiment was carried out on mesotrophic permanent grassland in the Solling Uplands of Lower Saxony, Germany from May to September of 2009 and 2010. Species diversity of paddocks was manipulated by the use of herbicides resulting in grass-dominated swards (7 species per 9 m2) in contrast to untreated diverse swards (14 species per 9 m2) with grasses, forbs and legumes. Each sward type was combined with three grazing treatments: C= cattle mono-grazing; S= sheep mono-grazing and CS= cattle and sheep cograzing. The six treatments were set up on paddocks of 0.5 ha each, replicated three times in blocks that were grazed rotationally. The main behavior patterns (grazing, walking, and ruminating) were recorded by conducting scan sampling every ten minutes from six a.m. to ten p.m. Secondary patterns (bites per minute, steps per minute, and bites per step) were obtained per core animal and observation day. Intake choices of Dactylis glomerata, Festuca pratensis, Lolium perenne, Phleum pratense, Taraxacum officinale, and Trifolium repens were obtained as follows: species were visually assessed in five 0.5 m2 subplots per plot immediately before and after a period of three days grazing on a plot. Jacobs’ selection index (JSI) was used to quantify the intake preference for single target species in relation to their proportion in the sward. JSI = ci – ai / ci + ai - 2ciai; where ci= % forage in the diet and ai = % forage in the pasture. Here, ai was evaluated by the difference between the percentage mass of each species before and after three days of grazing. For behavior patterns, there were important differences between sheep and cattle. Cattle varied their time budget and grazing behavior depending on the presence of sheep. However, plant diversity had no effect on cattle behavior. For sheep behavior, plant diversity rather than mono or co-grazing management was the determinant factor. Cattle mono-grazing on diverse swards spent more time grazing at lower ingestive rates. P. pratense was the most preferred forage species (JSI=0.62). L. perenne, T. officinale and T. repens were also highly preferred regardless of sward composition or type of grazer (JSI = 0.47, 0.32 and 0.27, respetively). Co-grazing facilitated a more homogeneous consumption of the main forage species. Co-grazing might have the potential to better maintain grassland biodiversity.

Forages and grazing in horse nutrition

Forages should be the basis of all diets in horse feeding. Therefore it is of major importance to determine which parameters will influence their quality. Changes on chemical composition along the vegetative cycle, nutrient losses during harvesting, preservation and storage are factors that could have an effect on nutritive value, as well on digestibility and palatability. A specific grazing and ingesting behaviour, linked to plant preferences and the selection of feeding sites will have an impact on biodiversity. This will determine the options on plant species and varieties and further management of pastures for horses. This book highlights the role of forages and grazing in horse nutrition and also gathers information about related topics, such as the contribution of local breeds for the sustainability and development of rural areas, their impact on landscape and relationships with environmental preservation. This book is the 6th volume in a scientific series conceived through the European Workshop on Equine Nutrition (EWEN) which falls under the umbrella of the Horse Commission of the European Federation of Animal Science (EAAP). All these materials provide an interesting basis for further discussion, not only in specialized forums, but also for those involved in horse production.

Grassland Management for Sustainable Agroecosystems

This book is a remarkable work that brings together the most recent international research on grassland management, covering a broad range of topics and geographical areas. The different contributions explore the complex relationships between landscape, climate features, and soil fertility with the support of observational data and modeling. Clearly, this is a wide and multifaceted area of research that opens up new prospects for the management of a biome, which should no longer be considered only as a feed resource for domestic herbivore farming, but also—and above all—as a source of ecosystem services to society and a contributor to the sustainability of agriculture. Textbooks like this positively demonstrate the importance and significance of how grassland science, when viewed in this way, can make tangible the progress in understanding the complexity of grassland management and its current and future challenges.

Grasslands of the World

This book brings together information on the contrasting characteristics, condition, present use and problems of the world's main natural grasslands. Since grassland is commercialized through the grazing animal, particular attention is paid to the livestock production systems associated with each main type. Grazing resources are more than simply edible herbage: many other factors have to be taken into account, notably water in all areas, and shelter in winter-cold climates. Seasonality of forage supply is a characteristic of almost all grazing lands, so the strategies for dealing with lean seasons are described. The main problems of each type are mentioned and possible strategies for their sustainable management discussed - taking into account their multiple functions, not only livestock production. The book is primarily aimed at agricultural scientists, educationalists, extensionists and decision-makers with interests in responsible use of extensive grasslands.--Publisher's description.

Ecology of Central European Non Forest Vegetation  Coastal to Alpine  Natural to Man Made Habitats

This handbook in two volumes synthesises our knowledge about the ecology of Central Europe’s plant cover with its 7000-yr history of human impact, covering Germany, Poland, the Netherlands, Belgium, Luxembourg, Switzerland, Austria, Czech Republic and Slovakia. Based on a thorough literature review with 5500 cited references and nearly 1000 figures and tables, the two books review in 26 chapters all major natural and man-made vegetation types with their climatic and edaphic influences, the structure and dynamics of their communities, the ecophysiology of important plant species, and key aspects of ecosystem functioning. Volume I deals with forests and scrub vegetation and analyses the ecology of Central Europe’s tree flora, whilst Volume II is dedicated to the non-forest vegetation covering mires, grasslands, heaths, alpine habitats and urban vegetation. The consequences of over-use, pollution and recent climate change over the last century are explored and conservation issues addressed.

Animal production and animal science worldwide

After the experience of the first volume, The World Association for Animal Production (WAAP) continues the publication of the Book of the Year series for the benefit of animal scientists and policy makers in the field of livestock systems. The WAAP asked the best known and significant animal scientists in the world to contribute to the preparation of this book. Following the success of the first volume of the series, the WAAP Book of the Year 2003, many authors from the six continents are contributing to this 2nd volume. The importance of this publication is to have already established a worldwide reference for the animal science and production sectors. There are the usual four sections that raised much interest in the previous volume of the series. The first section has six articles, describing the changing conditions of livestock systems in each of the six continents. The second section has more than twenty papers, describing the development of the many sectors in which the animal science field has been divided. The third section, dealing with contemporary issues, is declared by our readers to be the most interesting. It allows participating authors to describe current and significant issues important in these last years for the animal science and production sectors. The statistics produced in the previous volume are updated and enhanced with new figures in this book to form the fourth section. The papers included in this book speak clearly of the development in the last twelve months in the livestock systems worldwide. Major space is also devoted to the list of references from where every author can start to deepen his knowledge. This book is essential for libraries that want their readers to be easily updated. Also scientists, policy makers and scientific writers, who need, to enhance their competence, to have the most practical way of knowing what is going on in the world in the field of livestock science and production will find this book of great value.

Pastoral systems in marginal environments

Pastoral systems are some of the most fragile human ecosystems that exist and are under threat from the expansion of cultivation, changes in social patterns and climate change. These ecosystems are of major importance since they contain a rich biological and cultural diversity. The aim of the book is to take a holistic view of pastoral systems by bringing together papers written by specialists in plant and animal ecology with an interest in the application of their research with papers taking an economic and social perspective. The focus is on marginal environments where the issues are in greatest relief with the papers tackling key issues in semi-arid and disadvantaged temperate areas. The key issues relate to identifying the biological constraints of these pastoral systems, understanding soil/plant/animal relationships, exploring biodiversity, landscape and social issues in multi-functional systems and providing solutions to constraints through a number of case studies. By comparing and contrasting these two environments, the book will be taking a completely new approach to understanding how pastoral systems function and how they will evolve in the future. The book is of value to all those with an interest in pastoral systems by providing an up-to-date account of current understanding of these multi-functional systems and new insights into how they function and how they will develop in the future.

Grassland  a global resource

The concept of grasslands as a global resource is not new. Indeed many recognised authorities have been canvassing for a global approach to understanding, managing and exploiting this resource for many years. This is the first book that gathers together leading experts from around the world to outline our current understanding of this complex ecosystem, the ways in which it can be enhanced and utilised and where the research challenges are for the future. The following themes unite the book: - Efficient production from grassland; - Grassland and the environment; - Delivering the benefits from grassland. The reader is given an in depth understanding of the biology of the system and how grasslands are crucial for soil stabilisation and water quality. Secondly, much attention is given to how grasslands offer the possibility of increasing food supply and income generation, which is a hugely important but often ignored facet in today’s climate of extensification and biodiversity. Current advances in the grassland sciences have a proven potential to promote the economic development and environmental stability of regions, nations and peoples, particularly in some of the most resource-limited areas of the world. Approaches for achieving the most effective development and adoption of new technology are reviewed.

Forages  Volume 1

Forages, Volume I, Seventh Edition is the most comprehensive text available for teachers of undergraduate Forages courses. This edition will provide students with a good balance of scientific principles, to aid in integrating the concepts they learn, and practical information on forage identification, plant characteristics, management, and utilization that can be used by forage management practitioners. Grassland ecosystems are extremely complex, including the plant/animal interface as well as the soil/climate/forage interface and the text must support understanding and integration of all of these considerations. The coverage of the science behind the plant characteristics and responses make the book applicable in many parts of the world, while other region-specific management information relates mainly to North America. This edition has been updated to address emerging areas of study, including the use of forage plants as bioenergy crops. The editors also address the renewed national interest in environmental issues such as water quality, global climate change and eutrophication in the Gulf. This edition also addresses the role of forages for wildlife habitat and food sources, another area of increased interest in recent years. These revisions respond to the generational change taking place among forage scientists and teachers in recent years.
