AQA 8035 · 3.1.2.4 Cold Environments Check the specification (PDF) (opens in a new tab)
Economic development creates jobs, income and services by using an area's resources. Cold environments offer valuable minerals, energy supplies, fishing grounds and tourist attractions, but exploiting these resources can be difficult and expensive.
Alaska is our case study. It is the northernmost state of the USA, bordering Canada and the Arctic Ocean. Its environment varies: the south is relatively mild, while the north includes tundra and permafrost. Alaska also has mountains, glaciers and widely scattered settlements. These differences matter: not every part of Alaska experiences the same cold conditions or transport difficulties.
Alaska contains gold, silver, copper and zinc. Gold mining takes place in the Tintina Gold Belt, which extends across Alaska. Extracting and selling minerals creates employment and brings money into the economy. Mines also need transport, equipment and services, creating opportunities beyond the mine itself.
However, valuable deposits are not necessarily easy to reach. Remote locations make it expensive to transport workers, machinery and materials. Mining can also damage the environment, and processing gold ore can involve toxic chemicals. The value of a mineral deposit therefore has to be weighed against the costs of accessing and extracting it and the environmental risks involved.
Large oil and gas reserves occur in northern Alaska, particularly around Prudhoe Bay. Their extraction provides jobs and income, but oil must be transported to somewhere it can be shipped to customers.
The Trans-Alaska Pipeline carries oil about 800 miles from Prudhoe Bay to Valdez in the south. Tankers then transport it onwards. This provides an alternative to shipping directly from the northern coast, where winter sea ice restricts access. The pipeline shows the connection between opportunity and infrastructure: oil reserves have much greater economic value when there is a reliable route to market.
Alaska also has renewable-energy opportunities. Hydroelectric power uses flowing water, while geothermal energy uses heat from underground in tectonically active areas. These provide electricity as well as employment, although suitable conditions are not found everywhere in the state.
Alaska's surrounding waters support fisheries for salmon, crab and pollock. Commercial fishing supplies fish for sale and supports employment in catching, processing and transporting the catch. It is therefore an important source of economic activity for coastal communities.
Fishing also supports subsistence livelihoods among some Indigenous communities, including the Inupiat and Yup'ik. Fish provide food and other useful materials, so their value is not only the income earned from selling them.
The opportunity depends on maintaining fish stocks: reducing stocks through excessive catches would weaken future livelihoods. Some fishing employment is also seasonal, so a large industry does not necessarily provide year-round work for everyone.
Alaska attracts around two million visitors a year. Mountains, glaciers and wilderness scenery draw visitors, while activities include wildlife watching, kayaking, hiking and skiing. Cruises are particularly important: about 60% of summer visitors arrive by cruise ship.
Visitors spend money on accommodation, food, transport and activities. This supports jobs in hotels, restaurants and guiding, spreading the benefits beyond a single industry.
However, much tourism employment is seasonal and can be poorly paid. Adventure activities can also damage the landscape. For example, off-road vehicles can leave deep tracks in waterlogged ground after seasonal thaw, and the damaged surface can take years to recover. Tourism creates income, but its benefits depend on when visitors arrive and how activities affect the environment.
Winter temperatures in northern Alaska can fall below −30°C. Together with strong winds and limited daylight, this makes outdoor work difficult and potentially dangerous. Exposure threatens workers' health, while remote locations can make medical help difficult to reach.
Vehicles and equipment can fail in severe cold. When replacement parts or specialist repairs must come from far away, work can be delayed. Much construction is therefore concentrated in summer, when temperatures are warmer and daylight lasts longer. This short working season limits how quickly projects can be completed.
Alaska's large distances, mountainous terrain and scattered population make transport difficult. Some communities depend heavily on aircraft and ships rather than reliable road connections.
Access also changes with the seasons. Winter ice roads can provide temporary routes across frozen ground or rivers, but they can be dangerous. During warmer conditions, thawing ground can make some routes too soft to use.
These difficulties increase the cost of bringing in everyday goods and construction materials. They also make recruiting workers, reaching services and maintaining equipment harder. A resource may be valuable, but transport costs reduce how profitable its development can be.
Permafrost is ground that stays frozen for at least two consecutive years. Where it contains ice, thawing can cause the ground to settle unevenly. Heat from buildings or infrastructure can therefore undermine their own foundations, causing subsidence and damage.
Alaska uses specialised construction methods to reduce this problem. In permafrost areas, houses can be raised on stilts to reduce heat transfer to the ground. Sections of the Trans-Alaska Pipeline are also elevated. Roads can be built on 1–2-metre-thick gravel pads, which help limit heat transfer to the ground beneath. Water and sanitation pipes may be carried in insulated above-ground service ducts, called utilidors, to reduce freezing and avoid disturbing permafrost.
Specialised construction reduces heat transfer to permafrost, helping to prevent thawing and ground subsidence.
These methods make development possible, but require extra materials, design and maintenance. Providing infrastructure is therefore both a solution to Alaska's remoteness and a major development cost.
Alaska has several strong development opportunities rather than relying on only one resource. Mineral extraction, energy, fishing and tourism support different kinds of employment and income.
However, extreme cold, difficult access and unstable ground can make projects costly, slow and seasonal. The Trans-Alaska Pipeline demonstrates that high-value resources can justify major investment in specialised infrastructure. Overall, Alaska's opportunities are substantial, but their value depends on whether income can outweigh construction, transport and maintenance costs without undermining the resources and landscapes on which livelihoods depend.
Use Alaska as a named case study, with precise examples such as Prudhoe Bay, Valdez and the Trans-Alaska Pipeline.
Explain each point as a chain: a resource or physical condition → an opportunity or difficulty → its effect on development.
For an assessment, weigh economic benefits against limitations such as seasonal employment and high construction costs, then reach a supported judgement.
Distinguish the seasonally thawed surface layer from the permafrost beneath it. Heat from development can thaw permafrost and destabilise the ground.
