IB Geography Topic C.1.3 Challenges for Human Habitation and Resource Development Revision Notes (SL/HL) | RevisionDojo

Written by official IB examiners

Barriers to Development

Extreme environments present challenges to development of human settlements and activities.
These barriers stem from natural and human factors, such as:

Harsh climates.
Difficult terrain.
Limited resources.
Remoteness and inaccessibility.

Relief and Climate: Natural Obstacles to Development

Steep Slopes and Poor Soils

Steep Slopes:

Building infrastructure on steep slopes is costly and risky due to landslides and erosion.
Agriculture is challenging as soil is often thin and unstable.

Poor Soils:

In cold environments, soils are often frozen (permafrost) or waterlogged, limiting plant growth.
In deserts, soils are dry and lack nutrients, making farming difficult without irrigation.

Example

Himalayan Mountains: Steep slopes and thin soils hinder agriculture and infrastructure development, forcing communities to rely on terrace farming and traditional building methods.

Extreme Temperatures

Cold Environments:

Low temperatures reduce the growing season and increase heating costs for homes and businesses.

Hot Environments:

High temperatures increase water evaporation, leading to scarcity.
Infrastructure deteriorates faster under intense heat.

Human Discomfort: Challenges to Livability

Difficulty in Agriculture
