The United Nations Environment Programme (UNEP) has sponsored a programme of intensive research into the primary productivity of grass ecosystems in both the tropics and subtropics, resulting in this book. It therefore represents the first internationally integrated study of bio-productivity since the International Biological Programme (IBP) of the early 1970s. The large international team of scientists sponsored by UNEP identified five different grassland ecosystems, determining their levels of productivity as well as the effect of climatic variation on primary production and photosynthesis. The methods and results described indicate a three to ten-fold increase in estimates of productivity from the IBP figures, raising implications for a number of important questions such as: the understanding of how carbon is cycled, the environmental impact of removing grasslands, assessment of these ecosystems as genetic resources of productive grasses, assessing the impact of rising carbon dioxide levels in the atmosphere, and establishing ground truth data for remote sensing of grassland productivity.This book provides a comprehensive assessment of an extremely important but under-researched biome. It should be of interest to a wide range of environmental scientists, including ecologists, atmospheric scientists, biogeographers, and environmental physiologists.

Managed Ecosystems and CO2

Managed ecosystems cover a large part of the Earth's land surface, provide almost all of our food and most of our wood and fibre, and are increasingly a source of renewable energy. Forecasting the ability of managed ecosystems to continue these vital roles in a globally changing environment is an inter-disciplinary challenge.To elucidate the complex responses of managed systems to elevated [CO2], several free air carbon dioxide enrichment (FACE) facilities were established. These FACE systems allow large areas to be exposed to the elevated [CO2] we expect by the middle of the century. This volume summarizes the main findings from 13 experiments with annual crops, permanent pastures and plantation forests at 11 sites throughout the world during the past ten years. The results significantly alter our perception of how rising [CO2] will directly affect these managed ecosystems, with implications for policy, plant-breeding objectives and adaptation.
