THE THIN BLUE LINE

In 2008 astronauts aboard the International Space Station captured an image of sunlight as it passed through the Earth’s thin atmosphere, described as the thin blue line of “all that stands between life on Earth and the cold, dark void of space.” At the center of sustainability education is a discourse of climate change and life’s demise on the planet. In this short article, the contributing role of the United Nations University’s Regional Centres of Expertise (RCEs) for sustainability education is explored with respect to community-based climate change adaptation, notably through RCE Dhaka (Bangladesh) as an example of the challenges and opportunities for climate change adaptation in one of the most heavily populated megacities of the Global South.
