Twenty-ten was the International Biodiversity Year and the peak effort to raise awareness about biodiversity and its importance for human well-being. The outcomes were somewhat disappointing as the biodiversity loss is far from being halted. However, the IBY2010 was successful in putting the word “biodiversity” into common language on a European scale. It is therefore worth implementing the lessons learned. The main outcome is that addressing such a complex issue requires an integrated, multifaceted, well organized programme in the long run – a master-plan for biodiversity involving all kinds of activities inside and outside the museum. Three speakers from France, Italy and Netherlands will share their experiences and discuss projects with participants.
