Social media technology is having a dramatic impact on social and political dynamics around the world. The contributors to this book document and illustrate this "techtonic" shift on violent conflict and democratic processes. They present vivid examples and case studies from countries in Africa, South and Southeast Asia, Latin America as well as Northern Ireland. Each author maps an array of peacebuilding solutions to social media threats, including coordinated action by civil society, governments and tech companies to protect human minds, relationships and institutions. Solutions presented include inoculating society with a new digital literacy agenda, designing technology for positive social impacts, and regulating technology to prohibit the worst behaviours. A must-read both for political scientists and policymakers trying to understand the impact of social media, and media studies scholars looking for a global perspective.
