Impacts of climate variability and adaptation strategies on staple crop productivity in Sidama, Ethiopia.
Article in Scientific reports, 2025. 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
This study examines the impacts of climate variability and adaptation strategies on staple crop productivity in the Hawassa Zuria and Boricha districts of Sidama, Ethiopia. Using household survey data, multiple linear regression, instrumental variable (2SLS), and multinomial logit models were employed to analyze the relationships between climate factors, adaptation strategies, and crop productivity. Findings reveal that rainfall variation strongly correlates with Enset (r = 0.667) and maize (r = 0.654) yields, emphasizing the importance of moisture availability. Rising temperatures, especially minimum temperatures, negatively impact maize yields, with significant declines during the Belg (r = - 0.547) and Kiremt (r = - 0.508) seasons. Regression analysis shows that climate factors explain 54% of Enset and 77% of maize yield variability. Adaptation strategies such as irrigation, agroforestry, improved crop varieties, and water conservation significantly enhance yields. Improved maize and Haricot bean varieties increase productivity, while the impact on Enset is less pronounced. Fertilizer use benefits Enset and maize, whereas livestock fattening negatively affects maize due to resource competition. Adaptation adoption varies by agroecological zone, with Kolla zones favoring irrigation and water conservation. Access to climate information, agricultural extension services, markets, credit, and livestock ownership also influence adaptation decisions. To enhance food security and resilience, the study recommends promoting sustainable irrigation, increasing climate information access, and strengthening extension services. Policymakers should improve market access, support improved crop varieties and fertilizers, and educate farmers on livestock management. Integrating crop-livestock systems and prioritizing gender-inclusive policies can optimize resource use and build resilience.
