Dybul’s comments were music to my ears. For the past year, I’ve been part of the AidData Research Consortium’s project (ARC) to develop sub-national foreign assistance data. Already that project has worked to help geo-reference World Bank, African Development Bank and Asian Development Bank projects as well as foreign assistance from all donors in a number of countries. As many of you know, I’ve been part of climate vulnerability mapping for the better part of five years through my work on Africa through the Minerva Initiative and the CCAPS program at the Strauss Center. This fall we will embark on a new Minerva project to look at disaster vulnerability and complex emergencies in South and Southeast Asia. In this post, let me say a few more words on the importance of data granularity and aid targeting. Continue reading
