Small Islands in Big Oceans

Small Island Development States (SIDS) appear on the map as little dots of green in vast stretches of blue. In popular culture, they take turns appearing as idyllic holiday destinations... and as tiny landmasses always on the verge of drowning under rising sea level.
Just how exposed are these island nations to climate change effects? What makes them extra vulnerable? How are they dealing with this threat? We speak to IHE Delft's Erik de Ruiter van Steveninck.
(If you are from a Small Island Developing State--SIDS--here is a fellowship opportunity for you to study water management at IHE Delft: www.un-ihe.org/sids-fellowships-1 )
