Book Description
Agronomy of Grassland Systems presents a broad overview of grasslands agronomy incorporating both grassland and animal productivity within the context of farming systems. The authors, both experienced in the field of agriculture, examine the generation, vegetative growth, flowering, and seed production of grasslands, as well as mineral nutrition, pasture quality, and animal intake. The management implications of forage-animal interactions are considered with respect to improving the efficiency of livestock production, together with a concluding chapter on grasslands management within the framework of farming systems.

Book Description
Forages: The Science of Grassland Agriculture, 7th Edition, Volume II will extensively evaluate the current knowledge and information on forage agriculture. Chapters written by leading researchers and authorities in grassland agriculture are aggregated under section themes, each one representing a major topic within grassland science and agriculture. This 7th edition will include two new additional chapters covering all aspects of forage physiology in three separate chapters, instead of one in previous editions. Chapters will be updated throughout to include new information that has developed since the last edition. This new edition of the classic reference serves as a comprehensive supplement to An Introduction to Grassland Agriculture, Volume I.

Book Description
Can we unlock resilience to climate stress by better understanding linkages between the environment and biological systems? Agroclimatology allows us to explore how different processes determine plant response to climate and how climate drives the distribution of crops and their productivity. Editors Jerry L. Hatfield, Mannava V.K. Sivakumar, and John H. Prueger have taken a comprehensive view of agroclimatology to assist and challenge researchers in this important area of study. Major themes include: principles of energy exchange and climatology, understanding climate change and agriculture, linkages of specific biological systems to climatology, the context of pests and diseases, methods of agroclimatology, and the application of agroclimatic principles to problem-solving in agriculture.

Book Description
Grassland: Quietness and Strength for a New American Agriculture takes on the task of increasing our awareness of the vital role grass and grassland plants have in ensuring a sustainable future for America. Geared toward agriculturists, students, the public, and policymakers, Grassland aims to inspire and provide the reader the foundation needed to move into the future. Three main sections * track the history of grassland farming, highlighting the voices of grassland advocates * examine the current roles that grassland plays throughout the United States * look at the benefits grass-based agriculture can provide when grass is treated as an essential resource As Wendell Berry so eloquently argues in the foreword to Grassland, True farmers have minds that are complex and responsible...They understand and honor their debts to nature. They understand and honor their obligations to neighbors and consumers...In the time that is coming, we are going to need many more such farmers than we have, and we will need them much sooner than we can expect to get them.We will get them only to the extent that young people come along who are willing to fit their farming to the nature of their farms and their home landscapes, and who recognize the paramount importance of grass and grazing animals to good farming everywhere. This book will help that happen.

Book Description
Mountainous regions, which cover nearly half of the continent’s area, are in many ways of vital importance for the European population. They supply much of the continent ́s water, are centres of biological and cultural biodiversity, provide various opportunities for recreation/ farmers. But mountainous regions are characterised by permanent natural handicaps due to topographic and climatic restrictions on economic and agricultural activity. Because of the geographical constraints to farming, work productivity is on average lower by 28% in mountain areas compared with less favoured areas, and by 40% compared with lowlands. Agriculture in mountainous regions can therefore, in general, not compete with agriculture in advantaged lowlands and, with very few exceptions, cannot hope to become competitive in adopting intensive models in response to the growing global competition.

Book Description
Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Book Description
The biota of the earth is being altered at an unprecedented rate. We are witnessing wholesale exchanges of organisms among geographic areas that were once totally biologically isolated. We are seeing massive changes in landscape use that are creating even more abundant succes sional patches, reductions in population sizes, and in the worst cases, losses of species. There are many reasons for concern about these trends. One is that we unfortunately do not know in detail the conse quences of these massive alterations in terms of how the biosphere as a whole operates or even, for that matter, the functioning of localized ecosystems. We do know that the biosphere interacts strongly with the atmospheric composition, contributing to potential climate change. We also know that changes in vegetative cover greatly influence the hydrology and biochemistry ofa site or region. Our knowledge is weak in important details, however. How are the many services that ecosystems provide to humanity altered by modifications of ecosystem composition? Stated in another way, what is the role of individual species in ecosystem function? We are observing the selective as well as wholesale alteration in the composition of ecosystems. Do these alterations matter in respect to how ecosystems operate and provide services? This book represents the initial probing of this central ques tion. It will be followed by other volumes in this series examining in depth the functional role of biodiversity in various ecosystems of the world.
