Optional themes are a key component of the IB Geography syllabus as the examination on optional themes accounts for a significant part of your final grade. It is therefore crucial to make the right choice to maximise your grade. In this post we will break down all 7 options to help you make a well-informed decision.
IB Geography Options
The IB Geography syllabus offers 7 optional themes:
- Option A: Freshwater – drainage basins
- Option B: Oceans and coastal margins
- Option C: Extreme environments
- Option D: Geophysical hazards
- Option E: Leisure, tourism and sport
- Option F: Food and health
- Option G: Urban environments
SL students must pick two options while HL students study three options.
As mentioned, choosing the right options is crucial, as they play a significant role in your overall grade. In IB Geography Paper 1, which is entirely based on the optional themes, contributes 35% to your final grade for both SL and HL.

This theme is perfect if you're curious about the impact of water on humans and the planet.
In this theme, you will cover the following topics:
- Drainage basin hydrology and geomorphology
- Flooding and flood mitigation
- Water quality and water scarcity
- Water management futures
Option B: Oceans and coastal margins
This optional theme explores the importance of oceans and their role in shaping the climate and supporting life. You'll learn about ocean processes, how they link with the atmosphere, and the challenges of using oceans as resources.

- Geophysical hazard risks
- Hazard risk and vulnerability
- Future, resilience, and adaptations
Option E: Leisure, tourism and sport

- Stakeholders in food and health
- Future health and food security and sustainability
Option G: Urban environments
This optional theme focuses on the growth of urban areas, with more than half of the global population now living in cities, many of which are megacities. It explores how cities act as centers of social interaction, wealth generation, and consumption, with diverse patterns of wealth and poverty that can lead to conflict. Rapid urban growth, driven by transport improvements, creates challenges for city planners, including issues of sustainability. Key topics include the hierarchy of cities, the movement of people, and managing transport and waste. This theme is perfect if you're interested in understanding the life in a city and how it may be improved.
In this theme, you will cover the following topics:
- The variety of urban environments
