Defining adaptation

Adjustments in human and natural systems, in response to actual

or expected climate stimuli or their effects, that moderate harm or

exploit beneficial opportunities.

Mitigation:

reduce

emissions,

reducing

magnitude

of CC

Adaptation:

reduce

vulnerability

to CC

impacts,

reduce

losses

Adaptation and mitigation are complementary strategiesSource: UNDP

impacts

What are adaptation options?

Policy

Improve regulations, adjust incentive system, enhance participation of

affected communities

Infrastructure

For example: Water control – construct dykes, improve climate-resilient

infrastructure

Capacity development

Improve monitoring of sea temperature, erosion rates; improve

management skills

Research

Monitoring for policy advise, climate-resilient breeds/species

Good practices

Soil conservation, to improve agricultural yields, keep ecosystem

functions intactSource: Adapted from USAID 2007

Who acts and how?

Public sector responsibilities: setting rules and regulations for public

assets, public services, public goods, social protections, preventing

conflict and managing migration

Individuals and communities: household preparedness, autonomous

adaptation, share losses

Private sector: integrate climate risks into project design and services

(climate-resilient investments)

International cooperation: financial responsibility, resilient ODA,

capacity development

Addressing climate change

improves development effectiveness

Cost-effective: Ignoring climate risks can be costly. Prevention through

adaptation is cheaper.

Integrated: Adaptation looks at multiple stressors including climate and

non-climate, and can prevent ‘maladaptation’.

Flexible: Adaptation builds institutional and technical capacity to adjust

to risks over time as they evolve, improving flexibility.
