This book is primarily aimed at agricultural scientists, educationalists, extensionists and decision-makers with interests in the grassland and land-use fields. It brings together information on the characteristics, condition, present use and problems of the world's main natural grasslands. Since grassland is commercialized through grazing livestock, particular attention is paid to the livestock production systems associated with each main type. Grazing resources do not, of course, consist solely of the 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 described and possible strategies for their sustainable management discussed - taking into account their multiple functions beyond simply livestock production.(source:website).
