Nepal became a federal state in 2015. As a result, a new layer of local administration was created, and local governments took on a number of crucial responsibilities. For federalism to succeed at the local level, municipal governments, relevant civil society organizations (CSOs), private businesses and other actors need to use data. However, at the local level, data is used infrequently. This is not because of an absence of data, but largely because data is not accessible for use. Open Knowledge Nepal (OKN) has developed a solution to this – Integrated Data Management Systems (IDMSs). This brief provides a summary of the proposed solution, how it can be implemented and the challenges it faces.
