In each of its priority areas , the Mediterranean Action Plan's Priority Actions Programme (PAP) aims to enable interested countries of the Region to use the experiences gained and results obtained within completed or on-going national, bilateral and multilateral projects. Such a co-operation requires, among other things, the establishment of a reliable information system. To meet this requirement, the preparation of Directories of Mediterranean National Institutions and Experts concerned as well as compendium of projects relevant to the six PAP fields has been initiated.
