Crop productivity in southern Africa is stagnant despite moderate climate trends.
Article in Nature food, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Southern Africa faces high food insecurity and projected declines in agroclimatic conditions. Multiple satellite measures indicate that cropland productivity has stagnated for most of the region except South Africa in the past 20 years, in contrast to what official crop statistics suggest. Climate trends do not explain this stagnation, with the region experiencing more rainfall and less warming than most climate model projections. A change of course is needed before climate impacts accelerate.
