Networks are increasingly drawing scholarly and practitioner attention as very effective ways to organise efforts towards achieving certain social agendas. It has even led to the idea of a network society in which the information technology revolution has facilitated the emergence of a new economy, which is structured around flows of information, power and wealth in global financial networks. The handbook is aimed at global and regional networks, civil society organisations, policymakers and donors that support networks. By drawing on practical and academic sources, this publication endeavours to improve knowledge about how these networks of potential policy influences operate.
