This site has been produced by CALP to provide the main arguments and supporting evidence for using financial aid in humanitarian crises, where appropriate.

CaLP is a dynamic global network of over 90 organisations engaged in the critical areas of policy, practice and research in humanitarian cash and voucher assistance (CVA) and financial assistance more broadly. Collectively, CaLP members deliver the vast majority of humanitarian CVA worldwide.

Details of CaLP’s members and donors can found on our main website.

The evidence presented on this website draws from the best available material in both humanitarian and development contexts. There is a great deal of high-quality material available from development contexts; and less in the humanitarian sphere.

However, many of the same arguments apply. It is also widely recognised that humanitarian aid needs to be carefully designed to match each specific context it is delivered in. This makes it difficult to draw simple global comparisons between contexts. What’s right for Bangladesh may not be right for Bolivia.

If you have suggestions for improving the site, including additional evidence from reputable studies, or would like to find out more about CaLP’s work, please contact
