The AIDA 1 km resolution crop-specific rainfed and irrigated areas and green and blue water demands for Italy.
Article in Scientific data, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Climate and global changes alter natural resources demand and availability for meeting societal needs. Agricultural water use remains a priority, as agriculture remains the first freshwater consumer. Accurate mapping of irrigated and rainfed crops is crucial in agro-hydrological modelling for water management and policy. Taking Italy as prominent case, we present AIDA (Agricultural Irrigation Demand Analyzer), a set of high-resolution crop-specific maps of rainfed and irrigated areas and water demands. We combine very-high resolution crop-specific landcover datasets with cropland ground data and irrigation intensity maps to derive 1km-resolution maps for rainfed and irrigated crops in the entire Italian territory. A dynamic, spatially distributed agro-hydrological model with state-of-the-art inputs derives evapotranspirative demands partitioned into green water (from precipitation stored as soil moisture) and blue water (from irrigation). Our results have a linear correlation >75% and an error <20% w.r.t. subnational statistics in >80% of the areas. Despite limitations due to inputs, assumptions on hydrological processes and agricultural practices, AIDA complements existing hydrological models and land use datasets for Italy.
