The article wasn't accounting for other possible effects, it just jumped straight to concluding organic farming was the culprit. During the same time period covered by the policy, agricultural yields in the US dropped significantly as well, primarily due to pandemic and climate impacts. The article mentioned that the pandemic hit months after the policy was implemented and that devastated tourism, which was one of the backbones of Sri Lanka's economy. In earlier sentences, the article implies that the organic farming policy is solely responsible for the economic problems. In short, this is a biased and unreliable assessment of the policy's impacts.
