Integrated analysis of meteorological conditions and agricultural yields in Indonesia using causal learning and intelligent clustering for climate change mitigation.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Seasonal patterns strongly influence traditional agriculture in Indonesia; therefore, climate change is likely to have a significant impact on crop production. This study explores the dependency relationships between meteorological conditions and agricultural yields in Indonesia by integrating meteorological data with agricultural yield data. The datasets are collected from a wide range (2010 - 2024) at the district level. The meteorological data are obtained from 100 meteorological stations across Indonesia. The proposed approach employs the Peter-Clark (PC) algorithm to generate causal graphs and an Intelligent Kernel K-Means (IKKM) method to classify regions based on similarities in meteorological conditions and agricultural yields. IKKM is effective for mapping regions according to shared climatic and yield characteristics. This study examines five major agricultural commodities (cocoa, coffee, oil palm, cayenne, and paddy). The IKKM method successfully groups each dataset into three clusters, achieving an average Silhouette score of 0.35. The resulting causal graphs reveal dependency relationships between meteorological variables and crop yields. The dependent relationships indicate that rising temperatures are likely influence the declining yields of cocoa, oil palm, and paddy. Panel regression results indicate statistically significant (p-value [Formula: see text]) negative effects of temperature on agricultural land use and crop productivity. Minimum temperature significantly reduces cocoa land area, while minimum, maximum, and average temperatures negatively affect oil palm productivity. Average temperature also has a significant adverse impact on paddy productivity. These findings serve as a warning that climate change may directly and indirectly affect agricultural industries, with potentially severe impacts on key regions that contribute substantially to annual crop production.
