This collection of impact case studies illustrates how Philanthropy Support Organizations (PSOs) have implemented successful strategies to promote an enabling environment for civil society and philanthropy to thrive. Through eight cases from different countries, WINGS is bringing to the spotlight experiences that often remain behind the scenes. The publication also features specialized articles from the International Center for Not-for-Profit Law (ICNL), Forus and CIVICUS. Despite the challenges of shrinking space or lack of conducive fiscal environment, PSOs are creative and have tremendous positive impact on the field in response to these challenges. In this sense, this report is both a source of inspiration and a call to action.
