While having specific societal, economic and climatic conditions, in both cases water scarcity and water quality constitute a key role in problem dynamics: - water stress because of climate vs. high groundwater withdrawal rates; - high salinity because of high evaporation rates vs. high nitrate concentrations because of intensive agriculture; - in addition, both regions affected by dynamic population growth which intensifies water stress; - besides water quantity and quality, soil quality is another important parameter for water management.
