Abstract
This research addresses the problem of growing shortage of water resources from the world-wide viewpoints by modeling of the socio-environmental changes. There are two main objects; namely (i) to simulate and predict trends in the development of human civilization in different continents taking into account the effects of limited water resources through feedback links between water availability and the human actions, and (ii) to identify the important roles and effects of water resources that have on the growth of the world so as to aid in the planning of scenarios and policies for sustainable development. A model exploring water needs in the various continents is developed using System Dynamics. Identification of continents with acute water shortage and development limitations will also be possible with this model.
