Civil society organizations (CSOs) and individuals in Europe and Eurasia are increasingly learning to adapt to constricting civic space by finding new ways to advocate, to mobilize citizens, and to raise funds. Results from the 2016 CSO Sustainability Index (CSOSI) for Central and Eastern Europe and Eurasia, show that a number of countries, including Hungary, Russia, Azerbaijan, and Macedonia, have experienced democratic backsliding. This backsliding now threatens both the sustainability of CSOs, and also citizens’ fundamental freedoms of assembly, association and expression. From the mass protests in Macedonia to those in Poland, this year’s report shows that public demonstrations continued to be an important tool in 2016 to bring both the public’s and policymakers’ attention to issues of public concern. CSO sustainability in many countries in the region is increasingly challenged by decreased access to funding and constricting operating space. On a positive note, this year’s report highlights progress in financial diversification through innovative practices. As governments restrict access to foreign funding and reduce state funding to CSOs, organizations are increasingly turning to crowdfunding as an alternative source of funding. In addition, crowdfunding appears to be taking hold in a broader range of issue areas, as CSOs reported some success with fundraising for political and human rights activities in 2016, in addition to the social, environmental, and cultural activities it originally targeted. In other contexts, however, government restrictions have made it highly difficult for CSOs to operate. In Azerbaijan, for example, informal surveys indicate that at least two-thirds of CSOs have suspended their activities over the past few years, and surviving CSOs have lost most of their staff due to insufficient funding.
