IB Geography C.1.3 Challenges for Habitation and Resource Development Notes

Environmental Extremes Raise the Cost of Habitation and Development

1. Habitation requires reliable systems: People need water, food, shelter, energy, transport, health care and communication in places where one or more of these are difficult to provide.
2. Resource development requires access and continuity: A deposit may be valuable but remain uneconomic if extraction, labour, power and transport cannot operate safely and predictably.
3. Constraints interact: Steep relief increases isolation, cold damages infrastructure, and remoteness raises the cost of every repair or emergency response.
4. Technology changes feasibility rather than geography: Engineering can reduce exposure, but high maintenance, energy demand and environmental risk remain part of the decision.

Relief Restricts Settlement and Infrastructure

1. Steep slopes provide little level land: Housing, airports, farms and industry compete for valley floors, terraces and alluvial fans.
2. Slope hazards interrupt connections: Avalanches, rockfalls and landslides can close the few available roads and isolate communities from markets or medical care.
3. Construction needs stabilisation: Cutting roads into slopes can remove support, while retaining walls, drainage and tunnels raise project costs.
4. River valleys concentrate risk: Settlements follow water and transport corridors but may also occupy flood paths beneath unstable slopes.

Climate Creates Direct Human Discomfort

1. Cold increases heat loss: Wind, wet clothing and low air temperature raise the risk of frostbite and hypothermia and increase demand for insulated buildings and reliable fuel.
2. Heat strains the body: High temperature and strong solar radiation increase dehydration and heat illness, especially for outdoor workers.
3. Altitude limits oxygen uptake: Lower air pressure reduces work capacity and can cause acute mountain sickness before a person acclimatises.
4. Seasonality narrows operating windows: Winter darkness, snow cover, summer melt, monsoon rain or extreme daytime heat can restrict travel and construction to part of the year.

Water and Food Systems Remain Fragile

1. Cold environments lock water in ice and snow: Liquid water may be scarce in winter even where the total water store is large.
2. Permafrost limits drainage and cultivation: A shallow active layer restricts rooting depth and can become waterlogged during thaw.
3. Hot arid environments have a persistent water deficit: Domestic supply, irrigation, mining and ecosystems compete for rivers, aquifers and desalinated water.
4. Rainfall unreliability raises production risk: A failed wet season can reduce pasture and crops, while one intense storm may erode soil without providing lasting recharge.
5. Irrigation can create a new constraint: Poor drainage and high evaporation concentrate salts, which lowers soil productivity over time.

Remoteness Multiplies Every Other Constraint

1. Distance increases transport cost: Fuel, machinery, food and construction materials must travel farther, often through a small number of ports, passes or seasonal roads.
2. Sparse settlement weakens economies of scale: Hospitals, schools, power networks and communication systems serve fewer users across a large area.
3. Breakdowns last longer: Replacement parts, specialist workers and emergency support may take days or weeks to arrive.
4. Digital links reduce some isolation: Satellite communication and remote monitoring improve coordination but cannot move heavy equipment or evacuate people.

Resources Can Connect Remote Environments to Global Markets

1. Mineral and energy demand changes viability: High commodity prices can justify roads, ports, pipelines and worker settlements that would otherwise be too expensive.
2. Tourism creates a different connection: Mountain, polar and desert landscapes attract visitors, which supports employment but creates pressure on water, waste systems and fragile surfaces.
3. Renewable energy can become an advantage: High solar input, strong winds or steep relief may support energy projects where transmission and maintenance are possible.
4. Infrastructure has cumulative effects: A single road can open access for further extraction, settlement and tourism beyond the original project site.

Development Can Shift Costs to People and Ecosystems

1. Recovery is often slow: Cold, dryness and short growing seasons limit biological repair after trampling, spills, excavation or vegetation removal.
2. Water use creates conflict: Large projects can draw from aquifers or rivers used by local communities, livestock and wetlands.
3. Employment may be uneven: Specialist jobs and profits can flow outside the region while local people face higher prices, disturbance or loss of access.
4. Cultural landscapes require consent: Projects on Indigenous or customary land should be judged by participation, land rights and effects on subsistence practices as well as national revenue.
5. Boom-bust cycles reduce security: Settlements built around one resource can lose jobs and services when prices fall or extraction ends.

Adaptation Works Best When It Matches the Constraint

1. Cold-ground engineering: Insulated or raised foundations reduce heat transfer into permafrost and allow buildings to adjust to ground movement.
2. Water management: Storage, leakage control, recycling and carefully governed abstraction reduce demand on scarce sources.
3. Transport planning: Redundant routes, weather forecasting and seasonal stockpiles reduce the effect of temporary closures.
4. Environmental safeguards: Baseline surveys, restricted access, spill planning and funded restoration address risks before extraction begins.
5. Evaluation: A project is viable only when physical feasibility, social consent, long-term maintenance and environmental cost are assessed together.
