Most quantitative methods for identifying conservation-priority areas require more detailed knowledge about the extent and distribution of biodiversity than is currently available. Accelerated and irreversible losses of biodiversity call for the development of alternative methods to identify priority sites for biodiversity inventory and protection. We focused on the state of Arunachal Pradesh, a biodiversity-rich region in northeast India. We used a geographic information system and spatially explicit modeling to examine the correlation of land-cover and land-use patterns with biogeophysical characteristics and to project future patterns of land-use change. In 1988, 70% of Arunachal Pradesh was covered by forest. We project …

As conservationists well know, political borders rarely coincide with natural ecological boundaries. International borders such as that between the United States and Mexico traverse numerous ecosystems and watersheds. Many species of animals, birds, and insects regularly migrate between habitats across international borders. Conservation of Shared Environments collects works that take on the environmental issues along the U.S.-Mexico border. Covering topics as diverse as wildlife preservation, grassland ecology, water rights, indigenous peoples, and the ecological consequences of border security, the contributors to this volume offer not only scientific analysis but also insight on how to bridge the gaps between scientists, policy …

Some humans spend a tremendous amount of effort to change landscapes from a “natural” state to a “developed” state for a variety of desirable economic uses, such as urban, agriculture, transportation, and mining. Others spend a tremendous amount of effort to prevent such development in order to conserve the landscapes for a variety of important environmental uses, such as biodiversity maintenance, carbon storage, water filtration, and landslide prevention. It would be efficient in theory if a society were to focus its development efforts at locations that give the largest economic utility per area developed, and to focus its conservation efforts …
