RaMDry (Rangeland Model in Drylands) has been developped to study the dynamic use of forage ressources by ruminant herbivores in arid/semi-arid savanna rangelands with particular emphasis on effects of change of climate and management.
The model simulates the foraging activitives of herbivore (in its initial version only zebu cattle) herds in a heterogeneous environment consisting of several forms of land use and grasslands of two different grass species compositions over the run of the years.
Seasonal dynamics thereby affects the amount and the nutritional values of the available grass biomass.
A link of the vegetation regrowth with climatic data (daily precipitation and temperature) supports the study of effects of climatic change on the sustainability of rangeland management practices.
A detailed description of the model and the simulated processes (including the ODD protocol) can be found in the following publication:
