Applying ESD to promote wise water use and non-conventional water resources in the island of Folegandros


Many of the conventional methods of securing water supply (i.e. dam construction, water transfers, etc.) have proved to be non-sustainable in the long run. Non-Conventional Water Resources (NCWR) contribute to a sustainable way of improving access to water and to climate change adaptation; this way they are becoming increasingly important especially in water scarce countries. However, they are not well known to the citizens while several misconceptions persist i.e. when it comes to safety and hygiene issues. Proper education can effectively elucidate the misconceptions and support the diffusion of innovative ideas and solutions that NCWRs promise to deliver. The NCWRs provide an effective “vehicle” for inspiring responsible consumer and citizen attitudes.


The Zero Drop project coordinated by the GWP-Med  is aiming at enhancing the water capacity and availability of the arid island of Folegandros, that is confronting great water pressures particularly from the tourism sector during the summer period.

This will be done through a mix of targeted technical interventions (together with an educational and awareness raising component) tailor-made for the specificities of the island. The technical component includes the drilling of seawater boreholes to be used for the feeding of the existing seawater desalination units in Folegandros Island as well as for the rejection of the produced brine.
