EcoYield-SAFE: The biophysical model underpinning research article "Predicted yield and soil organic carbon changes in agroforestry, woodland, grassland and arable systems under climate change in a cool temperate Atlantic climate"

This version of EcoYield-SAFE model was developed from the Yield-SAFE model developed on the EU SAFE project (Silvoarable Agroforestry for Europe). The original equations are described in a paper by van der Werf et al. (2007).

EcoYield-SAFE was previously enhanced so that crop water use responds to the daily vapour pressure deficit that is dependent on the change of temperature and wind speed, promoted by the trees. Soil carbon has also been included in the EcoYield-SAFE model. This is based on the RothC model (Rothamsted soil carbon; Coleman and Jenkinson (2014)) and predicts soil carbon changes under different land uses and over time. These changes were undertaken during the EU AGFORWARD project (Grant number 613520). More recently, to determine the effect of climate change on tree and crop yields, EcoYield-SAFE v2 has been further developed to include the effect of increases in atmospheric carbon dioxide on the radiation use efficiency of the trees, grass, and crops. These changes were undertaken during the EU AGROMIX project (Grant agreement 862993).

A previous and simpler version of the model, named Yield-SAFE v2 is also available online (Burgess et al., 2023) in Cranfield University's CORD repository (https://dspace.lib.cranfield.ac.uk/handle/1826/22344).
