Ecosystem and agricultural modeling and evaluation


WADISCAPE ( WADI LandSCAPE )
simulates the effect of precipitation and grazing intensity on the biomass production and distribution of growth forms (e.g., grasses, woody plants) of semi-natural vegetation in a wadi landscape. It also estimates carrying capacity for livestock grazing.

MaxEnt Model (Maximum Entropy Model)
simulates the patterns of faunal biodiversity along a rainfall gradient and patterns of animal biodiversity under different land use and land management practices west to the Jordan River. It also simulates the distribution changes of crop pest species, e.g. fruit flies, in response to climate change and national planning.

Wheat Model
simulates a seasonal stress index (SI) based on daily calculation of potential and actual evapotranspiration and soil properties. SI is the ratio between actual and potential evapotranspiration. The evaluation of the grain wheat yields is based on SI value and nitrogen application. The model can also evaluate the effectiveness of suppression of direct evaporation from soil surface (mulching).

Cotton Model
evaluates cotton lint yield by simulation of the processes occurring in the soil, plant, aerial environment of the crop, and the interactions between them.

Land evaluation for effluent reuse
A GIS-based land suitability classification for effluent irrigation is being developed, considering the following five risks: mobilisation of inorganic adsorbable pollutants (e.g. heavy metals), soil salinization, slaking of the upper layers, boron mobilisation and mobilisation of nonadsorbable substances (e.g. nitrate).
