PREFACE

摘要

Although forests have been increasingly recognized for the wide range of environmental and social values essential to our planet's well being, unsustainable forest and land-use practices continue to destroy and degrade millions of hectares of forests in Asia and the Pacific each year. Vast areas of these deforested and degraded lands have been taken over by highly invasive grasses such as Imperata cylindrica. These largely unproductive grasslands harbor little biodiversity and provide very few livelihood options for local people.
