Climate change and rapid growth of urban population is dramatically affecting water management: by one side urban water demand is continuously increasing, on the other side urbanization has produced heavy hydrologic modifications at the water basin scale. Most of the current strategies about water management are only blindly focused on developing new sources in order to face the constantly increasing demand of the primary resource. The paradigm seems to be: in reply to population increase, growth of densely populated areas, improvement of the economic conditions, a corresponding increase in the total water consumption has to be met. This concept does not fit at all, in most of the occasions, with the present and future water availability of the concerned territory, and often leads to new infrastructure very expensive to build and maintain. But the paradigm can be shifted! And the shift must go towards sustainability.
However, is there consensus about what sustainability would mean in terms of water management? According to recent works, water would have to be used in cycles, or cascades, possibly with source separation of different flows in order to make treatment and reuse easier. Various water sources, rain, surface water, groundwater, would have to be integrated into the urban fabric, instead of being just safely evacuated, in order to provide water for consumption but also for ecosystems and ecosystem services. Actually ecosystems would be developed in order to provide services, which are now often sought through technical appliances. Nutrients contained in domestic wastewater would return to soil and crop production. The main investments shouldn’t go in building or upgrading sewer systems and supply nets, and should be focused instead at house-hold level, improving time by time the efficiency of the cycle for replying to the increasing demand.
The special issue of Water on Sustainable Water Management that we are proposing for your contributions will comprise papers on techniques for onsite water and nutrients saving and reuse such as rainwater harvesting, flow reduction, closed-loop or cascade water systems in residential and commercial buildings, wastewater segregation, greywater treatment, nutrients recovery.
Therefore, we would like to call for papers to disseminate and share findings on similar practices of sustainable water management in addressing problems and opportunities scientifically. Papers are selected by a rigorous peer review procedure with the aim of rapid and wide dissemination of research results, development and application in the wider area of sustainable water management.
Original research papers or critical reviews are invited.
