The submitted research must offer solutions addressing at least one of nine planetary boundaries and have the potential for measurable global impact. Sustainability scientists have identified nine planetary boundaries that we cannot cross without risking the collapse of life on Earth as we know it. Johan Rockström and Owen Gaffney have described these boundaries in their book Breaking Boundaries, as well as on the website of the Stockholm Resilience Centre. Action is needed now to prevent us from crossing these boundaries and, where we have already transgressed them, to guide a safe and just transformation of the world back to within Planetary Boundaries.
