Fertilizer Intensity, Agricultural Productivity, and Agricultural Emissions: Ratio Decomposition in a 24-Country Panel Wilman Santiago Ochoa Moreno (24506144) Liz Valle-Carrión (25064829) Econometric and statistical methods Agro-ecosystem function and prediction Agrochemicals and biocides (incl. application) nutrient use agricultural emissions land productivity ratio decomposition <p dir="ltr">Fertilizer use can raise agricultural output while increasing emissions, making ratio-based environmental indicators potentially misleading. This study evaluates these relationships in a panel of 24 countries from five regions. The productivity analysis covers 2002–2022, whereas the verified environmental series covers 2002–2019. Country and year fixed-effects models use Driscoll–Kraay standard errors. Fertilizer intensity is positively associated with land productivity (elasticity = 0.182; SE = 0.032), absolute agricultural emissions (0.123; SE = 0.026), and emissions per hectare (0.085; SE = 0.016), but negatively associated with emissions per unit of production value (−0.098; SE = 0.028). The ratio result therefore reflects faster growth of the production denominator and does not demonstrate absolute decoupling. The productivity estimate remains positive with lagged fertilizer, first differences, regional trends, macroeconomic controls, an irrigation subsample, alternative covariance estimators, and sequential country exclusion. The Agriculture Orientation Index is unrelated to productivity and absolute emissions, although it is negatively associated with the emissions-to-value ratio. The findings support nutrient-use efficiency and joint reporting of absolute and intensity indicators.</p> 2026-09-17T21:55:33Z Dataset Dataset 10.6084/m9.figshare.33899515.v1 https://figshare.com/articles/dataset/Fertilizer_Intensity_Agricultural_Productivity_and_Agricultural_Emissions_Ratio_Decomposition_in_a_24-Country_Panel/33899515 CC BY 4.0
