Islands are unique, diverse and vulnerable. They are important early indicators of the common challenges facing our global community. Island communities feel the impacts from natural disasters, climate change, overconsumption and other global changes more intensely, as these changes jeopardize their food, water, health and economic security. Today, many islands are demonstrating global leadership and rapid progress in addressing these challenges and inspiring others around the world.
