The international humanitarian sector is currently developing ways to measure progress on localisation following the commitments made at the World Humanitarian Summit in 2016.

Generating an evidence base on localisation is important in order to demonstrate what change is happening and the impact it is having. This report provides a baseline snapshot of localisation in Tonga.
