Unit 2a: Socio-ecological systems (PGDD512)

Socio-ecological systems

(SES) and exposure

Unit 2: PGDD512

Recap

• What is vulnerability?

• What is resilience?

• Where/how do they converge?

Recap

• Vulnerability and resilience as:

• Theories/concepts (what is this?)

• Methodologies (how do we measure these?)

• Real world practices (how do we apply?)

What is SES?

• In groups of 2.

• Discuss what you think a SES is and give an example.

SES

• Complex system of various interactions/components which are self-reflective.

• Resilient and adaptable.

• Use of eco-system services for sustainability.

Components of SES• Humans

• Ecosystems

• Biodiversity

• Habitats

• Social structures, interactions, cultures, traditions.

• Eco-systems services

• Sustainability?

Does it then make sense to have an ecosystems-based approach to disaster risk

reduction?

Main areas of interaction

• Ecosystems management

• Development planning

• Disaster risk management

• Climate change adaptation

In your own words…How can a better understanding of SES enhance disaster

risk reduction/climate change adaptation?
