Sri Lanka is exposed to a variety of extreme weather events and slow onset events which may both result in loss and damage. The frequency of extreme events such as seasonal floods, drought, landslides, strong winds and tropical cyclones have increased gradually. These environmental variations have a significant impact at the household level, especially on livelihoods, food security, water, health and infrastructure, and migration is an important strategy adopted by communities responding to climate change related implications. In this context, this study enhances the understanding on the nexus between climate change and migration in Sri Lanka by adopting a mixed-method approach.
