This study of aviation-related recreation loss shows that a survey primarily aimed at collecting information on invasive species’ pathways can also be used to estimate changes in pathway-related ecosystem services. We present a case study for Elodea spp. (elodea), Alaska’s first known aquatic invasive plant, by combining respondents’ stated pre-invasion actual flights with stated post-invasion contingent behavior, plane operating costs, and site quality data. We asked pilots about the extent of continued flights should destinations become invaded and inhibit flight safety. We estimate a recreation demand model where the lost trip value to the average floatplane pilot whose destination is an elodea-invaded lake is US$185 (95 % CI $157, $211). Estimates of ecosystem damages incurred by private actors responsible for transmitting invaders can nudge actors to change behavior and inform adaptive ecosystem management. The policy and modeling implications of quantifying such damages and integration into more complex models are discussed.

This report summarizes the fiscal effects of the commercial fishing, mining, and tourism industries on Alaska’s state government. The report calculates state revenue collected from each industry and compares it to the state’s expenditures for that industry. What revenue does the State of Alaska receive from commercial fishing? From the mining industry? From tourism? What does the state pay out to manage each resource? While the comparison between the state’s revenue and expenditures is useful information, this report is not an economic benefit-cost analysis.

Opioid Response Programs (ORPs) across Alaska partner with DHHS, Office of Substance Misuse and Addiction Prevention (OSMAP) to distribute opioid overdose rescue kits to members of the general public and to professionals (e.g., first responders, agency/organization staff, etc.). This work consists of two infographics, and is supported by the Substance Abuse and Mental Health Services Administration (SAMHSA) grant 1H79SP022117.

Food assessments are conducted for different reasons such as creating a more sustainable commercial food production system or to target particular policies. The main focus of this effort was to locate indicators that could be updated regularly so current information would be readily available and so that changes or trends could be monitored. Without knowing the current state of food-related indicators it’s difficult to make informed decisions about which issues and goals are priorities. We start with an overview of the food system model we used. Chapter 2 is a demographic overview of Alaska’s residents. The next five chapters present the indicators for each of the components of the food system. Chapter 8 contains the data we think would be need to develop a better picture of Alaska’s food system. The final section of this report is an index of the indicators: the name of the indicator, where the indicator appears in this report, the years of data included, the source (the agency or organization thatproduced the data), the source title for the data, and the location of the data, usually a Web address.

Metamorphosed porphyry copper, copper skarn, and volcanogenic massive sulfide (VMS) occurrences have been found in 5 key prospects within Devonian rocks of the Chandalar copper district, Alaska. The Venus, Victor, Eva, and Evelyn Lee prospects contain "proximal" porphyry copper/copper skarn mineralization, whereas the Luna prospect contains "distal" Cu-Zn skarn and Cu-Zn VMS mineralization. Porphyry copper mineralization is recognized by granodiorite composition meta-intrusives; zoned potassic, sericitic and propylitic alteration; and del34S values of -1.5 to -0.6 per mil. Skarns consist of andraditic garnet (Ad30-100) and diopsidic pyroxene (Hd9-46), and have del34S values of -4.7 to -1.1 per mil. Alteration types in intrusive rocks and adjacent skarn are generally compatible. VMS occurrences contain chloritic and silicic alteration, and massive sulfides have del34S values of -0.8 to 6.9 per mil, consistent with values from known Devonian VMS deposits.

"What is the economic contribution of wilderness and wilderness-protected ecosystems to Alaska’s economy? Tourism by nonresidents is the primary link that we consider between wilderness and the Alaska economy, although subsistence harvests and resident recreation clearly generate value for Alaskans. Here, we synthesize and apply existing data and research. We do not consider global ecosystem services provided by Alaska park lands and waters, nor do we assess activity that is not captured within the Alaska economy."

This assessment evaluates the effects of future climate change on a select set of ecological systems and ecosystem services in Alaska’s Kenai Peninsula and Chugach National Forest regions. The focus of the assessment was established during a multi-agency/organization workshop that established the goal to conduct a rigorous evaluation of a limited range of topics rather than produce a broad overview. The report explores the potential consequences of climate change for: (a) snowpack, glaciers, and winter recreation; (b) coastal landscapes and associated environments, (c) vegetation, (d) salmon, and (e) a select set of wildlife species. During the next half century, directional change associated with warming temperatures and increased precipitation will result in dramatic reductions in snow cover at low elevations, continued retreat of glaciers, substantial changes in the hydrologic regime for an estimated 8.5 percent of watersheds, and potentially an increase in the abundance of pink salmon. In contrast to some portions of the Earth, apparent sealevel rise is likely to be low for much of the assessment region owing to interactions between tectonic processes and sea conditions. Shrubs and forests are projected to continue moving to higher elevations, reducing the extent of alpine tundra and potentially further affecting snow levels. Opportunities for alternative forms of outdoor recreation and subsistence activities that include sled-dog mushing, hiking, hunting, and travel using across-snow vehicles will change as snowpack levels, frozen soils, and vegetation change over time. There was a projected 66-percent increase in the estimated value of human structures (e.g. homes, businesses) that are at risk to fire in the next half century on the Kenai Peninsula, and a potential expansion of invasive plants, particularly along roads, trails, and waterways.

Most remote rural communities in Alaska use diesel to generate electricity, but the high price of diesel is causing an increasing number to add a local power source that’s also renewable—wind. Our analysis is preliminary; most existing systems are new. Adding wind to diesel systems makes economic sense to customers if wind energy costs less than the equivalent energy cost of diesel. Our review of project histories did reveal some potential ways of improving the economics and performance of rural wind-diesel systems. Those include geographically and technologically aggregating projects to take advantage of economies of scale; employing skilled project developers who use technological innovations to increase wind-energy generation; having clear power-purchase agreements; having skilled and motivated local operators; establishing remote monitoring to alert project managers about problems and record maintenance and performance data; and hiring people with expertise in Alaska’s harsh climate.

Alaska’s geography—its location, climate, topography, and resources—have driven Alaska’s economy in the past and define and constrain its opportunities for the future. Alaska has abundant natural resources—oil, minerals, forests, fish. In the twentieth and twenty-first centuries, Alaska’s strategic location has contributed to the role of the military and more recently the international air cargo industry. Another Alaska natural resource--its natural beauty—represents an increasingly important natural resource. But Alaska’s remoteness from major markets, cold climate, mountainous topography, and permafrost make Alaska a costly place to extract resources compared with other parts of the world.
