Book Description
This volume comprises the proceedings of the Second International Rangelands Congress held in Adelaide, Australia in May 1984, and includes some 350 contributions drawn from 43 different countries. The Congress addressed the problem of the conflict between land-users and the degradation of this valuable resource. Some 40% of the Earth's land surface is and or alpine and therefore unsuitable for agricultural cultivation. Collectively, these lands are known as rangelands and in their natural state they constitute a habitat for grazing animals, both domestic and wild. Despite their low productivity, rangelands have been used for thousands of years as a source of food and fibre, but other uses such as mining, tourism, recreation and conservation are exerting increasing demands. The result is often conflict between land-users and degradation of the resource.

Book Description
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.
