A remote Pacific island nation could be the “litmus test” for global efforts to devise a sustainable development agenda.

Although Nauru (population 10,000) is so small it does not have an official capital, some of the world’s biggest problems can be found within its 21 square kilometres.

Climate change, youth unemployment, obesity and diabetes, are just some of the challenges facing the country, one of the smallest in the world, says Amina Mohammed, the UN Secretary-General’s Special Advisor on Post-2015 Development Planning.

Ms. Mohammed has just returned from Nauru. She tells UN Radio’s Donn Bobb that the country’s government is ready to engage in the debate to devise a global agenda to succeed the Millennium Development Goals.
