In this context regional changes of dominating

evaporation
economical development in a globalizing environment and its social consequences,
biodiversity respectively changes of the popUlation of species, and demographic
issues. It seems to be utopia to integrate al topics, processes and forcing factors from
climate to socio-economy and globalization at once in one "Global Change"
approach. Consequently it seems to be advisable to subdivide the problem into
overviewable and presently manageable research fields closely related to GEWEX.
The results of this sectoral research then has to be integrated at a higher level.
In the centre of Fig. 3 the research aspects internal to the Mediterranean basin
are shown in green boxes and its external relationships in the blue box at the right.
The four views at the system which are equivalent with the applied research tool are
shown in the red boxes. The relationship between the five research areas and the
four tools can be described as follows:
The work done by the community working on proxy and instrumentally
primarily operationally measured Mediterranean climate and hydrological data is
the basis for the understanding of the Mediterranean system and for the
improvement of the tools necessary to predict the future.
The analysis of proxy data is the only possibility to establish a long term data
base of paleo-climate changes. These data are needed to document past climate
changes as well as climate variability and to study their causes. The performance of
climate models can be tested against these proxy data and the interaction with
