China has the world’s largest navy and built over half of the world’s cargo ships in 2025. Where do they dock? At ports China financed around the world. @WSJ spotlights our port data, with analysis from @williamandmary alum Mike Studeman. Explore: china-ports.aiddata.org

Some Chinese grants to the DRC rise and fall with copper prices. 📊⛏️ The 2024 Sicomines amendment includes $324M in annual grants that drop to zero if copper hits $5,200/ton and rise 30% above $12,000. Could price-linked grants become a template? 🤔aiddata.org/publications/dem…

The Daily Show called China’s loan for Uganda’s main airport “debt-trap diplomacy.” Our director, Brad Parks, knew something sounded off. @AidData researchers dug in, found the key loan document, and published it with @FT. 🧵

China is a dominant maritime power, but where does Beijing direct overseas port financing, and to what end? @AidData researchers tackle it in a new chapter of "Traversing the Belt and Road" (@Harvard_Press), drawing on “Harboring Global Ambitions.” 👀 hup.harvard.edu/books/978067…

Droughts are getting longer, and farmers feel it most. Irrigation helps, but does it last? With @IFAD, @AidData is using satellite imagery to track long-term impact in Cape Verde, Ethiopia, and the Philippines. aiddata.org/blog/aiddata-par…

The EU will soon require proof that coffee and other commodities imported to the EU were not grown on deforested land. @AidData + COSA worked with Honduran smallholder coffee farmers to test approaches for data collection and deforestation monitoring.

Prior to its closure, USAID was one of the world's largest funders of conservation work — per a recent @insideclimate piece featuring @AidData Chief Economist @ariel_benyishay . 🧵

A USAID post-mortem flagged real inefficiencies — but BenYishay's own research on aid effectiveness consistently found USAID's programs delivered results.

To reimagine development data after the 2025 foreign aid cuts, @AidData compiled a list of 496 existing development data assets. We've now analyzed them, and some findings surprised us. 🧵🤔

🏢 Private sector use is bigger than expected: 87 of 496 assets (18%) have documented private industry use cases. This points to a promising sustainability path: selling derivative data/analysis to companies—while keeping core (non-derived) data public and free.
