Both Liu and Linderman point to the need for integrating ecology with human demography and behavior as well as socioeconomics to understand the role of protected areas in fostering biodiversity around the globe. This Landsat 7 project is part of NASA's Earth ScienceEnterprise, an interdisciplinary research program dedicated to improving our understanding of the Earth system and how it is changing due to both natural and human-induced processes.
