Diagnostic analysis for the rehabilitation of an irrigation system in the Stolac municipality (Bosnia Herzegovina)

The note presents the first results of the application of the diagnostic analysis procedure (an investigation process which aims at revealing problems, causes and effects related to the relevant actors involved in the system) to an existing irrigation system in Vidovo Polje, located at roughly 50 km from Mostar in Bosnia Erzegovina. Both internal social conflicts and technical inefficiency of the conveyance network came out from the survey and allowed the identification of the critical aspects of the irrigation system of Vidovo Polje. The methodology has been applied to a segment of the main channel, the secondary and tertiary channel of the irrigation system, considered representative of the network layout, focusing on the hydraulic and environmental aspects. The analysis carried out on the pilot segment of the channel may be transferred to the whole system based on the hypothesis of similarity. The solution tree, derived from the problem tree obtained through to diagnostic analysis, will help to identify the priority activities for the improvement of the conveyance efficiency of the irrigation network. This represents the fundamental step for the development of a participated management system program able to renewal the agricultural activities of a region, still suffering for the war effects.
