Book Description
Describes a research proposal on the role of marine-derived nutrients in sustaining the productivity of the Kenai River watershed which would involve testing stable isotopes, fatty acids, nutrients, contaminants, and foodwebs across different ecosystem components. The purpose is to support management agencies and interested persons in their decision making towards sustainable ecosystem management.

Book Description
The Kenai River Watershed (KRW), in south-central Alaska, is famous for its salmon. Urbanization along the lower river damages habitat and stresses these valuable fish. Are the river's salmon runs sustainable if recent land-use trends continue? I used interdisciplinary approaches from environmental history and landscape science plus technologies such as geographic information systems (GIS) to describe the watershed's land-use history from 1947 to 2010 and to link land use and watershed management to the sustainability of salmon runs. Although the area appears wild compared to many salmon-producing watersheds in other states, it has a long history of intense use and habitat degradation. Over the past 60 years the central Kenai Peninsula showed patterns of intensive riverfront recreational use, coupled with rural exurban sprawl in the uplands. Historic damage to salmon habitat included trampled riverbanks, bank hardening, dredged canals, diverted creeks, toxic spills, poorly built roads with impassable culverts, and the Cooper Lake Dam. More recent threats include cumulative effects, fishing pressure, climate change, invasive species, off-road vehicles, and potential septic leaks. Comparing the Kenai River case with land-use histories in 60 other salmon-producing watersheds suggested that the salmon runs are at risk due to delayed, cumulative effects of development and potential climate change. However, since the late 1980s people have taken unprecedented and progressive steps to protect healthy watershed habitat and reverse past damage. The high level of community commitment and reserves of undamaged habitat provide hope that Alaskans may learn from the grim fate of wild salmon around the world, and take better care of their salmon habitat. I concluded that the sustainability of the salmon runs hangs in the balance and offer a list of recommendations to maintain or enhance the resilience of the system.

Book Description
Conceptual separation of humans and natural ecosystems is reflected in the thinking of most natural resource management professions, including for estry, wildlife management, fisheries, range management, and watershed management (Burch 1971). Such thinking can deny the reality of the human element in local, regional, and global ecosystems (Bonnicksen and Lee 1982, Klausner 1971, Vayda 1977). As complex organisms with highly developed cultural abilities to modify their environment, humans directly or indirectly affect almost all terrestrial and aquatic ecosystems (Bennett 1976). Conse quently, information for managing watershed ecosystems is incomplete without consideration of human institutions and activities. Sociologists have studied the relationships between human societies and the land base or ecosystems on which they depend for over 60 years (Field and Burch 1990). These studies are distinguished by (1) a holistic perspec tive that sees people and their environments as interacting systems, (2) flex ible approaches that permit either the environment or human society to be treated as the independent variable in analyzing of society-environment re lations, and (3) accumulation of a substantial body of knowledge about how the future welfare of a society is influenced by its uses (or misuses) of land and water (Firey 1990).

Book Description
Within watersheds, social, economical, political and physical subsystems interact. While making decisions, decision makers should be aware of such interactions as any new policy will not only affect one subsystem. To see if a specific management policy is proper, an integrated study is needed of complicated water management system in the basin, considering major physical, social, economical and political aspects of it. System Dynamics provides a unique framework for integrating the disparate physical and social systems important to water resource management and can be used to comprehend the interaction of different drivers of the problem. Here, this approach is used to find, for different scenarios, how various options of demand management and population control can be more effective when combined with transbasin water diversions, increasing water storage capacity and controlling of groundwater withdrawal in the river basin. A simulation model is built based on Causal Loop Diagrams of the watershed problem to comprehend the dynamic and interrelated characteristic of the system, and convey experiences, lessons learned, and perceptions gained through the model development process.

Book Description
Few books published to date comprehensively analyzes how at statehood Alaska served as a leader in creating and enforcing environmental policy and how these early policies, together with the emerging activism of Alaska Native communities, played a part in the birth of the nationwide environmental movement. The book also addresses how the powerful extraction industry subsequently shaped the management of water and subsistence resources (as championed in particular by the Trump administration conservative and state politicians). After a campaign led by industrial interests and the republican party to discredit the environmental movement, today Democratic and tribal leaders and everyday citizen are working to limit the impacts of extraction interests. At the same time Alaska Tribes are boosting the role of traditional knowledge, rights of the river, and tribal self-determination movements in protecting water and subsistence resources.
