Tierras Argentinas — Open data atlas — Next.js

Lautaro Lacaze

An open atlas that shows how much Argentine land is in foreign hands, with the source next to every number. I designed and developed it end to end in 2026.

The challenge

The debate on foreign land ownership returned when Decree 70/2023 repealed Law 26.737 and its caps on foreign purchases. The data existed, but it was scattered across official records, press, academic reports and court files. There was no single place to answer the question and, above all, to verify the answer.

Design decisions

Opens with the question and one figure: about 13.3 million hectares, close to 5% of rural land, with a square grid showing the proportion at a glance
Province-by-province map, with the ranking bar capped at 15%, the legal limit
23 documented cases presented as case files: owner, country, hectares, provinces, conflict and sources
The law as a timeline: 22 milestones from 1878 to 2026, each with its source

Result

A public atlas covering all 23 provinces and CABA, 23 cases and 63 sources, with downloadable data (PDF + JSON, CC BY 4.0). Built with Next.js and deployed on Vercel.
