In Alaska, climate change is a supply chain
stressor jeopardizing food security

The cargo
ships lined up outside U.S. ports have revealed cracks in the global supply
chain. And while businesses and consumers are feeling the pinch, the problem is
projected to ease over time. But for America’s northernmost citizens, those
living in the Alaskan Arctic, more intractable supply chain woes are at hand.
They stem from the dizzying pace of climate change in the North and pose real
threats to food security, mental health and long-held cultural traditions.
For many
Alaskans, the supply chain that puts food on the table is a thing called
subsistence. It entails striking out onto the land or the sea to obtain foods
that are then shared with family and community members. Residents across Alaska
engage in subsistence, but in rural areas it can provide most of the protein in
individual diets. The practice is often informed by millennia of hard-earned
traditional knowledge about the land and, especially for Alaska Native people,
it is central to cultural identity.
The
diversity, abundance and nutritional value of Alaska’s food resources are
remarkable and range from crab and salmon to moose and caribou, along with a
seemingly infinite array of berries and other wild plants. For Alaska Natives,
it also includes legally protected harvesting of marine mammals such as walrus,
whales and seals. Combined, these foods staple together Northern diets,
providing the nutrition that both builds young minds and keeps elders warm.
Subsistence,
which Congress first protected with the Alaska Native Claims Settlement Act,
passed 50 years ago this month, is sometimes mischaracterized as a lifestyle.
But for many it is an economic imperative, especially in communities lying far
from the continent’s road system. These include dozens of Arctic communities along
Alaska’s far western and northern coasts, including Nome, Kotzebue, and
Utqiagvik (formerly Barrow). Here, store-bought food can be prohibitively
expensive, delivery is slow and healthy options are limited, making food from
the land an essential resource.
But
especially in Arctic Alaska, climate change is upending the subsistence supply
chain by rearranging every major element of the landscape, including its
vegetation, soil, snow cover, ocean temperatures, wildfire regimes and more.
Scientists and community members say it is swiftly turning the landscape into
something unrecognizable, which is disrupting the predictability of weather,
ice and other conditions long tied to subsistence.
Consider
the loss of sea ice as just one cascading example. Although autumn 2021 saw
some of the best seasonal sea ice formation in a decade, steady declines since
1990 have created vast areas of open ocean. Along with skyrocketing water
temperatures, it is believed to be connected in complex ways to fatal illnesses
in seals, dramatic shifts in fisheries central to both human and marine mammal
diets, as well as multi-year seabird die-offs, which have killed hundreds of
thousands of kittiwakes, puffins, murres and others.
It is
implicated in more insidious change, too. Scientists working off Alaska’s
Chukchi Sea coast recently discovered massive beds of the marine algae that
triggers deadly red tides, which could further disrupt northern ecosystems. The
phenomenon sparks fish and marine mammal die-offs and fishery closures in other
parts of the world but is not historically known to occur in Arctic waters.
Scientists have stopped short of predicting imminent red tides, but they say
the collapse of Arctic sea ice now heightens their likelihood.
All these
changes impact traditional foods, from bird eggs to shellfish to marine mammals
and beyond. But the concurrent effect on commercial fisheries, like this year’s
sharp cutbacks on Alaska’s famed crab fisheries, also threaten economic losses.
Those, in turn, impede residents’ ability to maintain boats and other equipment
necessary for subsistence.
Declining
sea ice also erodes vital wintertime travel routes, curtailing affordable
transit between communities and erasing the access that hunters rely on to
reach fish, seals, walrus, whales and other resources. It has also made coastal
communities susceptible to stronger wave action, which tears away at the land,
threatening schools, homes and even entire villages.
All that is
just from declining sea ice. Similar chain reactions can be traced through
thawing permafrost, warming rivers and changing precipitation patterns. The
latter was highlighted over Christmas weekend, when a major rain-on-snow event
struck the Fairbanks area. It destroyed the roof of one community’s only food
store, with the next closest option 70 miles away. But its long-term effect is
likely more hardship for declining caribou, another key human food source,
which struggle to survive when ice hardens the snowpack.
Just like
the many Americans whose lives are disrupted by strengthening wildfires,
droughts and storms, Alaskans are resilient and resourceful people. But their
experience at the leading edge of the climate crisis is a warning to the rest
of the country, especially as Congress ends yet another year without adequately
acting on climate.
