Interactively modelling land profitability to estimate European agricultural and forest land use under future scenarios of climate, socio-economics and adaptation [PDF]

open access: yes, 2014
Studies of climate change impacts on agricultural land use generally consider sets of climates combined with fixed socio-economic scenarios, making it impossible to compare the impact of specific factors within these scenario sets. Analysis of the impact

Correlation of yield and vegetation indices from unmanned aerial vehicle multispectral imagery in Thailand rice production systems

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Unmanned aerial vehicles (UAVs) equipped with cameras are used for collecting vegetation indices (VIs) for health monitoring of field crops such as rice (Oryza sativa). This study evaluated the relationship of VIs derived from multispectral UAV images at different buffer zones around the sampling points with rice biomass and grain yield from ...

Preservation of stable isotopic composition in charred grains: Implications for paleoenvironmental and archeological research

open access: yesJournal of Quaternary Science, Volume 40, Issue 4, Page 645-656, May 2025.
ABSTRACT The charring process can preserve archaeobotanical remains, providing valuable insights into past climates, agricultural practices, and plant growth conditions. However, the impact of charring on stable isotopes, especially at temperatures above 300°C, remains poorly understood.
