The book Governar no Século XXI: Desafios, Soluções, Liderança, by António Costa Silva, offers an in-depth reflection on how to govern in increasingly complex, interdependent and demanding contexts. Drawing on his experience as an academic, manager and former Minister for the Economy and the Sea, the author analyses the challenges facing the state and public administration, highlighting the importance of leadership, strategic planning and a culture of cooperation between the different sectors of society. Throughout the book, he argues for the need to reinvent the way we govern, with a focus on digitalisation, evaluating public policies and overcoming structural blockages that hinder collective action.
