Spatially Downscaling of Future Food Demand for Policy Planning

open access: yesWorld Food Policy, Volume 12, Issue 1, May 2026.
ABSTRACT Understanding the subnational dynamics of food demand, while accounting for the evolution of the agrifood system at the global level, remains a challenge for designing food policy to ensure food security. To link global agrifood systems with subnational food policy planning, we downscale per capita food demand for 62 food commodities at the ...

A score test for the agronomical overlap effect in a two-way classification model

open access: yesAgronomía Colombiana, 2014
In some agricultural research, a treatment applied to an experimental unit may affect the response in the neighboring experimental units. This phenomenon is known as overlap. In this article, a test to evaluate this effect in the Draper and Guttman model

fastbioclim: An R package for creating custom‐time bioclimatic and derived environmental summary variables

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 5, Page 1585-1594, May 2026.
Abstract Bioclimatic variables, widely used in ecological and biogeographical studies, are typically derived from 30‐year averages of monthly data (e.g. 1971–2000). Unfortunately, the use of these long‐term averaged variables often creates a temporal mismatch with the observational data collected, which potentially undermines how environmental ...
