The development of better procedures for monitoring the state of, and changes in, the world's forests is considered a major requirement for supporting national policy as well as the emerging science of global change. For nearly twenty years, space observation techniques have contributed to local and national forest inventories. This article assesses the potential of current remote sensing approaches and technologies for answering emerging needs in the field of forest assessment. Indications of what could constitute a global forest information system and the challenges to its development are described. Concepts expressed here are derived in part from presentations and discussions at the World Forest Watch Conference, organised as part of the International Space Year and held in Sao José dos Campos, Brazil, in May 1992.
