Grasslands are a resource of great economic importance, as the origin of much of the world's milk, wool and meat. Over the past 60 years great progress has been made in grassland science to cope with increasing pressures such as population growth and global warming. Ross Humphreys is a leading authority whose review will be of great significance to all grassland scientists and ecologists.

Grasslands around the world are a resource of great economic importance, as the origin of most of the world’s milk and wool and much of the meat. The growing world population and global warming have put increased pressure on the world’s grasslands. Ross Humphreys has played a leading role in the development of grassland science and in this authoritative review discusses how it has evolved over the past sixty years. Using the proceedings of the International Grassland Congress since 1937, Professor Humphreys identifies the shifting emphasis of the science, assesses the current state-of-play and looks at perspectives for the future. This unique review will be of great value to all grassland scientists and ecologists. • Looks at the changing emphasis of 7 key themes of grassland science over the past 60 years • Discusses global warming, plant improvement, soil fertility, grassland dynamics, grazing management and systems research
