Abstract
A water balance model is used to assess the relative impacts of global warming and soil
degradation scenarios on water resources in the future. Results indicate that overall global warming
will have a more widespread and greater impact on climate change. However soil degradation could
also play a significant role in water resource issues in the future. Based on the model results, wet and
dry climate regions are particularly susceptible to impacts from soil degradation. In general, reduced
water holding capacities will result in increased water runoff during wet periods, which will result in
higher overland flow rates and reduced recharge rates to groundwater. Water lost to runoff will also
increase deficits during dry periods, in effect increasing the duration and intensity of dry periods.
