The authors use the Net-Map method, an interview tool that combines stakeholder mapping, power mapping, and social network analysis, to examine the relationships between various institutions influencing the water sector in Pakistan. Group interviews were conducted with national stakeholders in Islamabad and with provincial stakeholders in Lahore to establish separate influence maps at the different scales. Interviewees were asked about four types of network relationships: formal authority, informal pressure, technical information, and funding. Network data was analyzed using social network analysis software and notes from interviews add further depth to the network observations. Concluding discussion focuses on the distribution of power and influence in the network and on the opportunities and challenges of recent governance reforms and implications for stakeholder engagement.
