Abstract
This paper reports on interdisciplinary research into the effects of climate change on three contrasting arid environments in Israel: (1) the rocky Negev Highlands, (2) the loessic Beer Sheva depression and (3) the sandy Nizzana area. Present day hydrological processes were combined with the study of environmental processes over longer time scales (back to 100 000 years). The effect of climatic change on environmental processes is shown to vary with local size conditions. The responses are partly controlled by two variables: the change in surface properties and the salt balance. However, ambiguities are also introduced because the scale of climate models cannot account for these local variations in surface properties and the fact that only average annual data are presented by these models. The results of a regional climatic change has a non-uniform spatial effect on hydrological processes and water regime.
