Summary: | An agricultural hydro-economic System Dynamics model is built to study optimal
solutions for economic efficiency of groundwater use and to achieve water and food sustainability
in Wadi Al-Dawasir. Seven scenarios are proposed for the period (2017-2030). These scenarios
are designed to study the anticipated effects of the government’s decision to stop growing fodder
crops by 2019. The results showed that the implementation of this decision would reduce the
cumulative depletion of water by 21 billion m3. In addition, the transfer from fodder to vegetable
farming is the least water consuming and offers higher value agricultural products than other
scenarios. |
