This document summarizes a review of initiatives that collect data on agricultural public expenditures (AgPE) across countries. It finds that while there are many efforts, it was unclear how they relate and what gaps remain. The objective is to provide an overview of the different initiatives to identify complementarities, challenges, and how collaboration could be improved. It analyzes initiatives by geographic scope, sectors covered, and types of data. The review finds some depths like disaggregation are more limited and proposes strategic options like strengthening coordination, collaboration, data access, and analytical capacity to better track AgPE globally. Next steps include finalizing the report and convening discussions on implementing recommendations.
