The document discusses the Smart Water Cycle for Doñana project which aims to ensure sustainable water management and the long-term preservation of the Doñana wetlands in Spain. The project consists of 4 linked sub-projects to address challenges in the region, including monitoring the ecosystem, assessing water resource availability, integrated water resource management, and exploring alternative water sources. The overall goal is to develop an integrated solution to balance water supply and demand through improved data collection, forecasting, decision support systems, and potential new water sources in order to protect this important ecological area.

 Oneof the most extensive wetlands and the biggestecologicalreservein Europe.
Smart Water Cycle for Doñana
 It covers543km2, of which 135 km2 are a
protected area (National Park,Ramsar site,
BiosphereReserve,EuropeanCommunity Special
ProtectionArea).
 Ecosystemservices:
• Agriculture
• Grazing
• Shellfish
• Tourism
 Lack of demonstration sites

4. Challenges in water management
• A natural reserve in danger (WFD)
• Thereareinteractions betweencoastal, surface
and ground water including
overpumping aquifers
• Water withdrawals for irrigation, most of
them illegal
• Polluted rivers due to mining activity
surround the area
• 15 different administration entities have
competences
• Strong environmental, socioeconomic
and political challenges

5. Smart Water Cycle for Doñana (SWC) objectives
 Ensurethe long term preservation of such an important ecosystem
 Focus on achieving a good quantitative and qualitative status of water bodies in Doñana
 Managing existing water resources on an optimized way withstrong ICT tools development
 Generating alternative resources that allow to meet the water unbalance of the area
Smart Water Cycle for Doñana

Smart Water Cycle for Doñana goes beyond scientific and technological
innovation by bringing a social dimension to solve a flagship environmental
challenge

6. SWC strategy
 Definition of the social and environmental parameters with KPI
 Assessment of supply and demand for existingwaterresources
 Improved monitoring and smart management of the waterresources
 Assessment and validation of complementarytechnologies and measurements
to enhance the wateravailability
 Full scale implementation of the integralsolution
 Through a strong Public-Private Partnership
 Involvement of stakeholders
 Efficient dissemination plan
 Marketing of the solution for its exportation
