Why is everybody suddenly talking about innovation? For example, only 4 articles on the topics “sustainability” and “innovation” where published in 1997. Ten years later, the figure is 100 (Source: Social Science Citation Index). But what is ‘innovation’ really, and why does it matter? In this recent blog post, you can listen to Resilience Alliance member Frances Westley, as she explores the role of social innovation. You can also listen to Rebecca Hanlin (Open University, UK) as she elaborates the need for innovations in health. Political scientist Jan-Peter Voss (CTS, Berlin) explains in a Skype-interview, how innovations cascade across levels in governance. Enjoy!
