Water resources in the Mediterranean
Water is a rare and fragile resource in the Mediterranean.
The Mediterranean climate is typified by an enormous irregularity in
the distribution of rainfall in space and time.
Annual mean precipitation values(in mm H2O)
Water resources in Greece
Greece is a typical Mediterranean country, with unbalanced
rainfall, where integrated water management systems are still
either deficient or absent
Management efforts are
concentrating on the
implementation of provisions of
the Water Framework Directive.
There are parts of the country that
are under severe water stress, such
as numerous islands of the Aegean
Sea.
Continuing growth puts pressures on
vulnerable water resources
• Demographic growth
• Urbanization
• Intense irrigation
• Touristic activities
• Disposal of effluents
• Climate Change
Causes Consequences• Threats to the quantitative
and qualitative regenerative
capacities of freshwater
• Degradation of the quality of
freshwater and ecosystems
• Growing cost of water
Urgent need for
Non Conventional Water Resources
• There is an urgent need to enhance water efficiency
and to explore further alternatives to ensure water
availability using innovative approaches.
• The revival of traditional water
harvesting and management
techniques, which have been
overlooked in favour of modern
technologies, sometimes less
sustainable, can be a move in
this direction.
� To position rainwater harvesting as a helpful tool for climate
change adaptation at local level.
� To promote rainwater harvesting as a sustainable way of
providing community access to water in water scarce areas,
thereby contributing to the improving ecosystem conservation.
� To promote multi-stakeholder partnership for local rainwater
harvesting initiatives.
� To promote knowledge and sharing of experiences on aspects of rainwater harvesting systems and approaches.
The project is essentially a “demonstration case” aiming at
educating and stimulating people of all ages towards a
“new” (eventually not so new) “water culture” necessary for
addressing the current water needs.

RWH: A Multi-Stakeholder Project
RWH Project ActivitiesRWH Project Activities
� Installation of Rainwater Harvesting Systems in selected public buildings/properties (schools, town halls etc.). The harvested
rainwater is for several non-potable uses (watering, toilet flushing
etc.) contributing to water supply consumption reduction and
water saving.
All installations are harmonized with the architectural identity of
the islands and the landscape. They include both above- and
under-ground tanks.
� Educational Programme: (i) Production of educational material,
‘The Gift of Rain’ (ii) Educational programme for students aged
10-15 years old (iii) Teacher training on education for sustainable
development, focusing on water issues.
� Training Seminars for local technicians/workers (construction
workers, plumbers, engineers etc.).

A Success Story
Expected Outcomes:
Stakeholder mapping and analysis (background & interview based),
Stakeholder Consultation for (i) prioritization needs, (ii)
development of shared vision, (iii) identification of potential
practical applications, (iv)(potentially) voluntary agreement
among stakeholders for better water management through NCWR.
