To avoid reinventing the wheel, the development of indicators should build on existing efforts towards effectively monitoring and evaluating the implementation of GCM commitments over time, using available data and indicators as well as guidance. SDG Targets and Indicators already provide a good starting point for this purpose. Looking at the topic of human mobility in the context of disasters, climate change and environmental degradation, for example, one of the domains (domain 5) of SDG Indicator 10.7.2 focuses on the mobility dimensions of crises, including those linked to disasters and environmental factors, which links to GCM Objective 5. Similarly, in relation to GCM Objective 2, other SDG Targets and Indicators may be relevant, include those aiming to monitor national disaster risk reduction policy efforts (indicators 1.5.3; 11.b.1 and 13.1.2), national climate change adaptatio...

We fully agree with the call to not reinvent the wheel and acknowledge that there are many existing sets of indicators that measure different aspects of migration governance such as KNOMAD’s toolkit for measuring policy and institutional coherence for migration and development, IOM’s Migration Governance Index (MGI), and the Migrant Integration Policy Index (MIPEX).

However, a policy measure might seem effective and adequate in recognizing rights to migrants de jure. However, if the required resources are lacking, then practical implementation may be ineffective and migrants de facto unable to exe...
