The webinar was organised jointly by BiodivERsA and EKLIPSE, as a follow-up of the Joint Foresight Workshop "Social Innovation and Nature-based solutions" that was held in Brussels in December 2016. EKLIPSE & BiodivERsA wanted to further support the debate with this webinar to bring some background on the plurality of views and the existing typology, to illustrate that with examples, to explain a few key principles for effective implementation, and to identify limitations and remaining questions.
