Meet the Experts

The Climate Security Expert Network

If it's a CSEN report, you can trust that it was written by someone with real local expertise about the region in question. Our experts either come from the region or have years of experience working there--and our reports go through an international peer review process.

Moreover, the risk briefs have been discussed with stakeholders in and from the respective regions at dialogues in Dhaka, Nairobi, Niamey, Rabat, Kathmandu, and Tokyo.
