In Sweden, the twenty-first century came with a new generation of biosphere reserves (BRs). Between 2005 and 2011 , five nomination forms for BRs were submitted to the Man and Biosphere (MAB) Programme, hosted b the United Nations Educational, Scientific and Cultural Organization (UNESCO) for inclusion in the World Network of Biosphere Reserves. Interestingly, in all of these cases, actors at different leels mobbilized and collaborated to endorse the BR proposals. The inclusion of governmental and municipal autorities, civil society and in some cases the private sector, has provided an opportunity for inter-sectoral leaning on sustainable development. Two more nomination forms were submitted in 2018, both clearly showing that they had learned from previous nomination processes and from the actual implementation of the BRs.
