With the United Nations “Rio+20” Conference fast approaching, the word “sustainable” is more present than ever – including in our own State of the World 2012 publication – sometimes to the point of excess. For low-lying island nations, however, “sustainability” is more than the mild, consensual definition of the United Nations: it is really about maintaining the environmental conditions necessary to sustain human life as we know it. Many countries, regions, and cities fear the potential consequences of runaway climate change, be it desertification, droughts, or increasingly frequent storms. What makes the cases of countries like Kiribati, Tuvalu, Micronesia, and the Maldives so unique is that their very existence as sovereign states is at stake, and some of their younger citizens might live to see that existence brought to an end – the IPCC (2007) has predicted 0.5 to 1.5 meters of sea-level rise before the century is over.

Whether that prediction turns out to be overly optimistic or gloomy is still to be determined, but low-lying island nations are not passively waiting to find out. Despite their remarkably low carbon-footprints, they are trying to lead by example when it comes to mitigating greenhouse gas emissions: while an international treaty would only, by the timeline set at the 2011 climate change negotiations in Durban, South Africa, come into force in 2020, the Maldives and Tuvalu (among others) have pledged to become carbon-neutral by that date. But these nations have understood that due to natural – as well as political – inertia, more emissions and increased sea-level rise are already locked in. This is the basic reasoning behind the islands’ adaptation policies, which are only as varied as they are extreme. For instance, though the President of Kiribati Anote Tong admitted it sounded “like something from science fiction”, the country seriously considered building offshore floating islands and higher seawalls last year, for a total cost of about US$ 3 billion – quite a challenge for a country with a GDP of US$ 200 million in 2011 (about US$ 6,000 per capita).
