Satellite Earth Observations and Their Impact on Society and Policy

Abstract

Large-scale environmental problems have become prominent byproducts of the interactions between human activities and the biophysical settings in which they occur. Some of these problems, such as the destruction of tropical forests, arise in areas within the jurisdiction of individual states but have consequences (e.g., biodiversity loss, climate change) that are regional to global in scope. Other problems, including the seasonal thinning of the stratospheric ozone layer, occur in areas that lie beyond the jurisdiction of nation states. Still others, like marine dead zones, originate in areas within the jurisdiction of individual states but can spread and have impacts on areas outside these jurisdictional boundaries. In all these cases, efforts to come to terms with the relevant problems require international (often global) responses that call for transboundary cooperation and, more often than not, eventuate in the development of regulatory arrangements designed to limit or even prohibit the human actions that give rise to the problems.
