Science Year 2012

As a partner of the Science Year 2012 "Project Earth: Our Future", Verlust der Nacht is supporting the dialogue about sustainable development in keeping with the motto 'Living off the harvest rather than the seeds'.

Logo Science Year 2012

The Science Year 2012 "Project Earth: Our Future" is dedicated to research for sustainable
development. Sustainability research is the key to the future. We need to find a research
approach that encompasses economic, ecological and social aspects – without solving one
problem at the expense of another.

The Science Year 2012 "Project Earth: Our Future" poses questions that have more than one
correct answer: How do we want to live? What do we want to live on? And how can we preserve
our environment? These are three central dimensions of the Science Year for sustainable

The term 'sustainability' is frequently used and it is defined in different ways. According to the
Federal Government, sustainability means cutting only as much wood as can grow back again,
and living off the harvest rather than the seeds. Each generation must solve its own problems
and not burden the next generations with them.
The Federal Ministry of Education and Research currently funds more than 500 international
projects in 62 countries across five different continents with the aim of promoting sustainable
