This research explores one aspect of social-ecological change in the context of an Alaskan human-Rangifer system (HRS), with the goal of understanding how households respond to perturbations during times of rapid change. It is a case study of the community of Anaktuvuk Pass, Alaska, USA, from the mid-1970s to 2003. In this study, resilience is defined as a system’s capacity to maintain its fundamental structure and functioning despite perturbations (Cumming et al. 2005, Folke 2006, Kofinas et al. 2010, Wilson 2012). I focus on households as one element of social resilience (Adger 2000) while recognizing that the study community is reliant on ecosystem services (Berkes and Jolly 2001, Folke 2006). I view resilience in the context of transition theory (Wilson 2012), in which communities are continually in a process of change. Disruptions, perturbations, stresses, or shocks are key points in the transformation process (Wilson 2012). I examine perturbations and follow Turner et al. (2003), who define perturbation as a disturbance that originates beyond the system. In contrast, stresses originate within the system. McCarthy and Martello (2005) and others (Folke 2006, Wilson 2012) note that changes can have both positive and negative effects and can create opportunities for innovation and development. Adaptations are structural changes in response to external circumstances (Young et al. 2006). In this study, adaptations are changes that households make in their productive activities to minimize risk to their resources and livelihoods (Berkes and Jolly 2001, McCarthy and Martello 2005).
In the case of Anaktuvuk Pass, a community with a subsistence-cash economy, households moved from relying primarily on ecosystem services to being connected to the global economy while remaining reliant on the local ecosystem. During the study period, households diversified, and movement was from a simple to a more complex economic society (Wilson 2012) while maintaining essential elements of the former. The embedded assumption that complex society is a more resilient society remains an open question (Timmerman 1981, Turner et al. 2003). Adaptive responses of households allowed them to persist during the period of perturbation. Following the perturbation, households incorporated wages from jobs into a subsistence-based economy to create a mutually reinforcing mixed economic system in which elements of the old remained while the parts changed (Anderies et al. 2004).
Perturbations had two forms: restrictions on caribou hunting and increased job opportunities. I identified the mid-1970s as the period of perturbation for the community of Anaktuvuk Pass. A short but severe disruption to harvests came in 1976, when the Alaska Department of Fish and Game (ADFG) imposed limits on caribou hunters in response to a perceived crash in the caribou population. During this same period, oil production started at Prudhoe Bay, Alaska, bringing jobs and transfer income to Anaktuvuk Pass residents. Nearly all residents work for the North Slope Borough (NSB) rather than directly for oil companies. The borough was established in 1972 and began to levy taxes on oil infrastructure located on borough land. To generate cash quickly, the borough began to issue bonds, and over time used tax revenue to repay them. Bond revenue provides funding for major infrastructure improvement projects (Morehouse et al. 1984). The projects preferentially hire borough residents.
During the time when caribou harvests were restricted, households incorporated wages from jobs into the social-economic system. Households returned to caribou harvesting after restrictions were lifted, but also maintained income-earning jobs. I view households as integral to the system, highly dynamic, and as both responding to formal institutional change affecting the HRS (Kofinas and Russell 2004) and greater global economic change. In the North American context, transformation of a socioeconomic system is defined as a transition from semi-nomadic caribou hunters to a hybrid economy mixing subsistence hunting and fishing, transfer income, and wages. The existence and durability of a mixed economy in rural Alaska has been well documented by other researchers (VanStone 1960, Kruse 1991, Kirkvliet and Nebesky 1997, Magdanz et al. 2004, Wolfe 2004, Wolfe et al. 2009). I also report community-level demographic measures identified by Adger (2000) as indicators of resilience. My research questions were: What adaptive strategies did households use in response to hunting limits imposed in 1976? How can sustained caribou harvests and sharing be seen as household-level proxies for resilience? Are there indicators of community-level resilience corresponding to household changes? Have households in this HRS undergone a transition?
In this section, I describe the study area, its residents, and its fundamental structure, and identify essential elements that, if impaired, would threaten its continued existence (Timmerman 1981, Anderies et al. 2004, Cumming et al. 2005). For Anaktuvuk Pass, the essential elements are household caribou hunting, cultural continuity, and community-level demographic stability. Anaktuvuk Pass is located in the Brooks Range of Alaska’s North Slope, USA, and is situated in a caribou migration corridor (Fig. 1). Caribou migrate in the spring and fall (Brower and Hepa 1998). The 2010 community population of 324 is predominantly Iñupiat (Inuit of Alaska). The community is accessible by air in summer and by air or snow machines in winter.
Hall et al. (1985) provide a historical overview of community settlement, reporting that Iñupiat caribou hunters have been living and hunting caribou in the interior part of what is now the North Slope borough since the 1400s. Although caribou make up the largest share of subsistence harvests, local residents also harvest fish, birds, moose, sheep, plants, and berries. Since the Anaktuvuk Pass area was first inhabited in the 1800s, residents relied primarily on a single resource for subsistence needs, making the community potentially more vulnerable to disruptions compared to multi-resource communities on the coast (Adger 2000). In the early 1900s, the caribou population collapsed, and Iñupiat people either died of starvation or moved away (Hall et al. 1985). Moving away from the Anaktuvuk Pass area is evidence of mobility as a resilience characteristic. Mobility has been recognized as a key resilience strategy for households prior to permanent settlements (Berkes and Jolly 2001, McCarthy and Martello 2005).
By the 1920s, the caribou population began to recover, and 10 years later, people returned to hunt during winter. During the 1940s, several families returned, and by 1950, the population was 66 (U.S. Bureau of the Census, no date). At that time, store-bought foods were not available, and people traveled by dog team. In 1968, oil was discovered at Prudhoe Bay, and decades of rapid change followed. In 1970, 99 people lived in Anaktuvuk Pass, and all but two were Alaska Native (U.S. Census 1970, summary file 4 [U.S. Bureau of the Census 1996]). The population more than doubled to 203 by 1980 (U.S. Census 1980, summary file 3 [U.S. Bureau of the Census 2008]), and has increased steadily since then (U.S. Census 1990 and 2000, summary file 3 [U.S. Bureau of the Census 1993, U.S. Bureau of the Census 2002]). Today, approximately 9 out of 10 residents are Alaska Native (U.S. Bureau of the Census 2012).
With oil production and the creation of local and regional governments came job opportunities and wage earnings. Local and borough government jobs allowed for subsistence leave and scheduled work around community calendars. In 1980, 1990, and 2000, no one from Anaktuvuk Pass worked at Prudhoe Bay (measured by travel time to work using U.S. Census summary file 3 computer files), possibly because oil production takes place in an industrial enclave, with two weeks on and two weeks off, and with no accommodations for subsistence. No data are available for 2010 because the U.S. Census discontinued use of the long form, which included questions about income, education, occupation, travel time to work, migration, disabilities, and language.
At about the same time as economic development was gaining momentum, big changes were coming for caribou harvests. Statewide economic growth and institutional development led to tension between state government and traditional subsistence communities (Morgan 1976, Morehouse et al. 1984, Spaeder 2005, Spaeder and Feit 2005, Dayo and Kofinas 2010). Until the 1970s, there were no seasonal restrictions or bag limits for caribou. In 1976, the State of Alaska began to implement management plans for caribou by imposing per-hunter limits and seasonal closings; this was a shock to the people of Anaktuvuk Pass, who relied on caribou as their primary food source and food sharing as a cultural tradition. ADFG officials cited a catastrophic drop in the population of the Western Arctic Caribou herd as the reason for the limits (Fig. 2). According to ADFG, the herd numbered 242,000 in 1970 and declined to < 100,000 by 1976 (Morgan 1976). However, there was a common opinion by local native hunters that the population census was flawed and therefore inaccurate (Kruse et al. 1998).
Caribou is the key subsistence species for Anaktuvuk Pass households. The absence of animals disrupted subsistence practices. Subsistence involves cultural values and attitudes, mutual respect, sharing, resourcefulness, and an understanding (both conscious and mystical) of the intricate interrelationships that link humans, animals, and the environment (Alaska Natives Commission 1994). In Anaktuvuk Pass, as in other rural Alaska communities, harvest sharing is not only a cultural tradition, but is also a result of efficient production. ADFG subsistence harvest data show a consistent pattern of harvest sharing in Anaktuvuk Pass. Approximately one-half of households reported hunting, and nearly all hunters reported sharing their harvests (Community Harvest Subsistence Information System data files, ADFG 2013). This behavior is consistent with subsistence harvest patterns elsewhere in rural Alaska. In an analysis of subsistence harvest data across rural Alaska, Wolfe and Walker (1987) found that ~30% of households account for 70% of the harvest, with wild foods distributed to other households in the community, a pattern known as the 30:70 rule. Writing about Anaktuvuk Pass, Brower and Opie (1996) describe community feasts where successful hunters distribute their harvest to other people in the community. For Anaktuvuk Pass, a relatively small number of hunters traditionally produce most of the harvest. This practice magnified the hardship of government-imposed per-hunter bag limits.
Data sources for proxy measures of resilience come from four household censuses, two household sample surveys (a randomly selected subset of households), and ADFG subsistence harvest surveys. The ADFG surveys ask a series of questions about each species. In the case of caribou, the questions are: Did your household use caribou? (“Use” includes using meat for human and animal food, as well as hides, antlers, and other caribou parts for clothing, art, and other purposes). Did your household attempt to harvest caribou? Did your household harvest caribou? Did your household give away any caribou? Did your household receive any caribou? ADFG survey methodology is described in detail by Fall (1990).
Household survey data include only Alaska Native households, defined as having at least one adult who self-identifies as Alaska Native. The NSB conducted a sample survey in 1978 and censuses in 1988, 1993, 1998, and 2003. Sample survey data were also obtained from the 2003 Survey of Living Conditions in the Arctic (SLiCA; Kruse et al. 2008), which is a household survey of aboriginal people in the Arctic. The survey included aboriginal households in the United States (Alaska), Canada, Greenland, Norway, Sweden, Finland, and Russia (Chukotka and the Kola Peninsula); the Alaska and Russian portions of the survey were funded by the National Science Foundation (http://www.arcticlivingconditions.org/). Martin (2010) discusses the survey in more detail.
The 1978 NSB survey is interesting because it covers the time when caribou hunting limits were in place and includes questions about how households adapted to the limits. However, it did not ask people if they hunted caribou in 1977 because of sensitivity and confusion about the regulation. Nearly all surveys included household demographics, employment, income, housing, hunting and fishing activities, and subsistence food consumption. SLiCA and the NSB 2003 census took place in the same year. Where possible, I used data from the NSB census because it contains information on 92 households, whereas the SLiCA sample is 10 households.
Caribou harvest level is a measure of household resilience. Survey data indicate that hunting restrictions disrupted harvests and food supply (Table 1). Of the households in the NSB 1978 survey, 71% reported that they hunted caribou prior to the imposed limits. Nearly all households (96%) reported that they had less food during the restrictions than in the prior period, and 96% reported that the caribou regulations were the reason why. Hall et al. (1985) wrote that in 1976, hunters chartered an airplane to find caribou. However, this strategy did not overcome the problem of bag limits and was very expensive. During the time of the ban, households adapted to imposed limits by eating more store-bought food, by eating less meat, or both, and households did not substitute other subsistence foods for caribou (Table 2). Hall et al. (1985) also noted that there are few good fishing locations nearby.
Despite the disruption caused by the imposition of hunting limits in 1976, households returned to caribou hunting after the restrictions were lifted (Table 2). Except for 1994, the number of animals harvested has been fairly constant over the 16 years. In addition to counts of animals harvested, the 2006 survey also contained information about households. Nearly everyone in the community, i.e., 92% of households, reported using caribou.
Cultural continuity is another measure of household resilience. I used data on household participation in a broad range of subsistence activities over time, household consumption of subsistence foods, and harvest sharing as indicators of cultural continuity. Households reported that they maintained subsistence activities, consumption, and sharing over the 25-year period (e.g., fishing, hunting caribou, gathering berries, sewing skins, trapping, and hunting marine mammals; Fig. 3). A high percentage of respondents reporting that they participated in marine mammal harvests in 2003 is due to the small sample size; two households reported hunting for seals. Participation levels in non-caribou subsistence activities were similar in 1978 to subsequent years, indicating that in 1978, people did not shift from caribou harvests to other activities. In 1978, no one reported that they participated in whaling, walrus, or seal hunting. This is consistent with the lack of alternative subsistence resources nearby, the expense of equipment and travel, and lack of knowledge specific to some harvests (e.g., marine mammals). It is also consistent with the observation by Wolfe (2004) that culture determines which species will be harvested. For the 12 months prior to each survey, > 50% of households reported that one-half or more of their subsistence food came from their own harvests (Table 3). This share has not decreased over time. In addition, since 1978, ≥ 71% of households report that they gave subsistence food to other households, and > 80% of households reported that they received food over the previous 12 months (Table 3).
In 1970, 10 people (approximately 13% of the population aged 16–69) worked at wage jobs during the previous 12 months, and per capita income was < $100 USD (U.S. Census 1970, summary file 4 computer file [U.S. Bureau of the Census 1996]). By 1980, 45 people had wage jobs, and per capita income had risen to approximately $11,000 USD (U.S. Census 1980, summary file 3 computer file [U.S. Bureau of the Census 2008]). Compared to 1970, employment increased sharply during the 1970s and remains at high levels, with nearly 9 out of 10 working-age people holding jobs during the previous 12 months (Table 4). Combining caribou harvest information (Table 2) and employment data (Table 4) from 1978 suggests that during the caribou shortage, people went to work and used wage earnings to buy more food. In the years following 1978, people continued to work after the hunting restrictions were lifted (Table 4).
Household participation in wage earning and subsistence activities is a household adaptive strategy. Once the hunting restrictions were lifted, households returned to caribou hunting but retained jobs, marking the emergence of a hybrid mixed subsistence-cash economy, which extended beyond earnings from trapping to includes wage and salary earnings. The move to a mixed economy was not so much the result of hunting restrictions as it was of a significant increase in job opportunities. Increasingly, subsistence hunters need cash to help support their traditional way of life (Kruse 1991, Kirkvliet and Nebesky 1997, Berman 2009). Cash also supports modern conveniences that have become part of Iñupiat life. Rifles have replaced bows and arrows, snow machines have replaced dog teams, and freezers improve food storage. Jobs provide money for equipment, fuel, and ammunition. Technological advances have also made hunting and fishing more efficient, allowing people to live in villages near jobs and schools, and hunt and fish on the weekends or in their spare time (Berman and Kofinas 2004). Taken together, increased employment, improved but more expensive equipment, and continued subsistence indicate that households are using some of their wage earnings for subsistence activities. By 1978, ~57% of households participated in the wage economy and subsistence hunting and fishing, similar to later years (Fig. 4).
As oil and tax revenues began to flow to the state of Alaska, the NSB, and the Arctic Slope Regional Corporation (ASRC), households began receiving dividend payments, adding to the mix of cash and subsistence. Beginning in 1972, ASRC began paying shareholder dividends. In 2009, ASRC paid out approximately $5700 (USD) per person to 9600 shareholders (State of Alaska 2011). In 1982, households in Anaktuvuk Pass began receiving additional income when the Permanent Fund Dividend program began to make annual payments to every Alaskan from oil revenue earnings (Alaska Permanent Fund Corporation 2013, unpublished report).
Following Adger (2000), I used stable age structure and slow but continued population growth as indicators of community level resilience. Anaktuvuk Pass is more than five-times as large as it was in 1950, and 9 out of 10 people are Alaska Native. Even during the mid-1970s, the population increased despite the drop in caribou availability. This is in sharp contrast to the turn of the century, when people left the area after the caribou population crashed. Unlike some communities in which nearly all the young Alaska Native women have left (Martin 2009), there are nearly equal numbers of young adult men and women in Anaktuvuk Pass (Fig. 5). Relatively large numbers of 10–19-year-olds indicate that, if conditions remain the same (including the cost of living), the population could be stable in future years, and there are enough young adults to maintain caribou harvest traditions.
I presented modest empirical evidence to support a simple idea: changing adaptive strategies helps households rebound from perturbations. Adaptive strategies that promote the ability to rebound involve incorporating new opportunities while maintaining key cultural and social functions. In this case, households adapted to a perturbation, i.e., hunting restrictions, by taking advantage of job opportunities and substituting store-bought for harvested foods. Following the perturbation, households incorporated earnings from jobs into the subsistence economy and returned to caribou harvesting and associated sharing traditions, and at the same time, they created a highly integrated mixed cash-subsistence economy. During the time span of this study (1978–2010), while households were adapting to change and incorporating new opportunities, the population of Anaktuvuk Pass continued to grow, and the age-sex structure of the community remained stable. The response to the disruption in 1970 was different from the outmigration and starvation of the early 1900s, possibly because of the availability of wage earnings to maintain food supply. The mixed economy connects households of Anaktuvuk Pass to the global economy while continued caribou hunting and harvest sharing maintains their connection to the HRS. This research shows how households adapted to disturbances from the combination of worldwide economic, ecological, and state-initiated institutional changes. The households of Anaktuvuk Pass have demonstrated resilience in the sense that they incorporated new resources to maintain Rangifer harvest while increasing material well-being. Households have taken advantage of the opportunities that came from rapid change to manage vulnerability and risk.
According to Cumming et al. (2005), one of the aims of applying resilience theory to empirical case studies is to identify strategies for continued resilience. The lessons from Anaktuvuk Pass in the 1970s may be, as Holling (1973) writes, to maintain flexibility above all else. The work of Ostrom (1990) and others (Anderies et al. 2004) indicates that the best way to maintain flexibility is to allow for those who have the highest stakes in the system to have the strongest voices in regulation. Continued pressure on the HRS in Anaktuvuk Pass comes from climate change related events and changes in the global economy (Kofinas and Russell 2004). Increased fire frequency and intensity could damage lichen-dominated habitats on which caribou rely (Joly et al. 2011). Rising fuel prices are driving up transportation costs as well as rapid increases in the cost of living (Fried and Robinson 2008). High fuel prices and other costs have put pressure on households by making hunting more expensive while forcing them to rely more on subsistence foods (Brinkman et al. 2014). How these factors will affect households in the HRS are subjects for future research.
