Description
Guyo Dureti, Hadi Hadi, and David Wuepper measured farm policy effects worldwide in 2026. Cropland damage threatens food output and the environment. Governments answer with many public policies. Judging whether those policies work is hard. The team used satellite records of cropland condition over two decades. The data held tens of millions of measurements. They applied two quasi-experimental methods to isolate policy effects.
On average, the policies improved cropland condition worldwide. The gain was at least a few percent, and possibly more. Effects varied sharply by country, from none to very large. Stronger institutions and bigger budgets explained much of that spread. Payments to farmers for green practices worked well. Soil and land-use rules also worked well. Each added policy of those types brought a measurable gain. The authors offer rare global evidence that farm policy can slow land damage.
