The Weekly Tradecast looks at low-lying coastal countries and the unique threats they face from climate change with UN Trade and Development (UNCTAD) senior economist Mussie Delelegn. 
The resilience and prosperity of these countries is the focus of the UN’s fourth International Conference on Small Island Developing States in late May.
Known as SIDS, these dozens of small island states are the most vulnerable to extreme weather, rising seas and coastal erosion brought on by climate change.
The human and economic costs are enormous. If climate trends continue, some of the islands could soon disappear under the waves. 
Listen in to Mussie Delelegn to learn how the SIDS can build their economies, protect their people and mitigate the impact of climate change.
