A new water resource planning technique was developed for regional and local levels of water management in Ukraine. For this purpose, methodology, methods and tools, as implemented in the Water Scenarios for Europe and for Neighbouring States (SCENES) project, were studied and adapted to the specific situation of the Crimea pilot area in the South Region of Ukraine. For testing of the new planning techniques, a participatory scenario development process was organised and implemented with Crimean stakeholders. Various facilitation tools and supporting measures were incorporated into the methodology for general scenario development. Causal Loop Diagrams on the problems of irrigation performance in Crimea and enrichment (down and cross scaling) with results from other pilots were also used. These tools increased stakeholders' insights and quality of outcomes and stimulated social learning. The scenario development process ends up in the formulation of storylines, action plans and policy recommendations.
