One of the many highlights of the 2015 General Elections was the role that technology played in empowering Nigerian citizens and CSOs to organize, collaborate and mobilize. The Content Aggregation System for Elections (CASE2015), developed by the Yar’Adua Foundation, was an example of multi-stakeholder collaboration in sharing election observation information. The platform retrieved more than 2.6 million micro-reports from social media and received over 11,000 reports from registered observers in the field. These reports enabled volunteers to identify 1,542 critical incidents that were escalated to INEC and relevant security agencies in a timely manner.
