Alaska

The First Regular Session of the thirty-first Alaska Legislature began on January 15, 2019, and ended on May 15, 2019. A First Special Session was held from May 16, 2019, through June 13, 2019, with a Second Special Session following from July 8, 2019, through August 6, 2019. The 2019 legislative session resulted in virtually no oil and gas legislation being passed, as the Alaska Legislature focused primarily on legislation regarding the State budget and the funding of the Permanent Fund Dividend. Despite the uncharacteristic lack of oil and gas legislation, the Legislature addressed the prevalent issue of oil and gas leasing in the Arctic National Wildlife Refuge (“ANWR”) through the passage of Senate Joint Resolution No. 7.

Comprehensive valuation of the ecosystem services of the Arctic National Wildlife Refuge

Ecosystem services (ES) have been well studied in most biomes, but the Arctic tundra has received little attention, despite covering over 10% of terrestrial Earth. Using established ES methodologies, we calculated values for the United States Arctic National Wildlife Refuge, a region virtually undisturbed by humans, but slated for future oil and gas drilling. We estimated the Refuge is worth about 1,709 USD/hectare/year, equal to over 13 billion USD annually.Globally important services, such as climate regulation (e.g., carbon storage) and non-use services (e.g., aesthetic information), contributed the most value and were similar to valuations from more productive ecosystems. Local services made smaller contributions to the total, but they remain vitally important to local indigenous cultures. Strikingly, a contingent valuation survey of U.S. residents found that, after neutral educational information, willingness-to-pay to maintain the Refuge in its current state exceeded estimated values of the oil and gas deposits.Our study shows that citizens may value Arctic habitats beyond their traditional economic development potential. Our comprehensive ecosystem services valuation suggests that maintaining the Refuge in its current condition (i.e., de facto wilderness) with its full range of ES is more valuable to humanity compared to development for oil and gas.

House Passes Measure to Protect Arctic National Wildlife Refuge

The measure, which would repeal an oil and gas development program in the refuge, now needs to pass the Senate, where there is stiff opposition.

Changes in Vegetation Cover of the Arctic National Wildlife Refuge Estimated from MODIS Greenness Trends, 2000–18

Trends and transitions in the growing-season normalized difference vegetation index (NDVI) from the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite sensor at 250-m resolution were analyzed for the period from 2000 to 2018 to understand recent patterns of vegetation change in ecosystems of the Arctic National Wildlife Refuge (ANWR) in Alaska. Statistical analysis of changes in the NDVI time series was conducted using the breaks for additive seasonal and trend method (BFAST). This structural change analysis indicated that NDVI breakpoints and negative 18-yr trends in vegetation greenness over the years since 2000 could be explained in large part by the impacts of severe wildfires. At least one NDVI breakpoint was detected in around 20% of the MODIS pixels within both the Porcupine River and Coleen River basins of the study area. The vast majority of vegetation cover in the ANWR Brooks Range and coastal plain ecoregions was detected with no (positive or negative) growing-season NDVI trends since the year 2000. Results suggested that most negative NDVI anomalies in the 18-yr MODIS record have been associated with early spring thawing and elevated levels of surface moisture in low-elevation drainages of the northern ANWR ecoregions.
