INVESTWATER co-develops decision-support tools, business models and an adaptive scalability framework.

WHO

INVESTWATER consortium includes 11 partners from 7 countries across Europe and North Africa.

Latest news

Follow the latest news from INVESTWATER: project meetings, stakeholder workshops, training events, publications and milestones from our four pilot sites across the Mediterranean.

The multi-criteria decision analysis (MCDA) framework is widely recognised as a key component of robust managed aquifer recharge (MAR) planning. However, many existing applications still produce deterministic, “best-estimate” suitability maps that do not fully capture spatial heterogeneity or the uncertainty […]
We were excited to host the Kick-Off Meeting of the INVESTWATER Project in Paphos on 9–11 June 2026! INVESTWATER is a PRIMA Partnership -funded (Section 1, Innovation Action) research project developing innovative Nature-Based Solutions (NBS) for sustainable water management, climate […]

Working together for water resilience

Eleven partners across seven countries are demonstrating nature-based solutions at four pilot sites to improve groundwater resources and climate resilience.

11 partners

Universities, research institutes, SMEs, municipalities and authorities join forces across the Mediterranean to co-develop nature-based water solutions.

4 pilot sites

Contrasting sites in Cyprus, Portugal, Tunisia and Italy test nature-based solutions under diverse hydrogeological, institutional and socio-economic real-world conditions.

~1,360 km²

Four catchments spanning seventy to six hundred square kilometres provide the ground where recharge, quality and ecosystem benefits are measured, analysed and improved.

7 countries

Cyprus, Germany, Portugal, Italy, Tunisia, Greece and Spain contribute complementary expertise to address water-related challenges in the Mediterranean basin.

Integrated solutions

INVESTWATER develops, validates and scales integrated nature-based solutions through advanced analytics, field demonstrations and participatory planning approaches.

Advanced Decision support Tools

A suite of tools integrating hydrological modelling, earth observation, machine learning and socio-economic analysis to inform water planning and optimise site-specific NBS interventions.

Adaptive Scalability Framework

A participatory methodology combining biophysical, socio-economic, institutional and governance analysis to guide the scaling of NBS-to-MAR solutions across the Mediterranean and beyond.

Our pilot sites

INVESTWATER technologies, methodologies and tools are demonstrated in four pilot sites.

Kouris River Watershed (Cyprus)

Located in a semi-arid region of southern Cyprus, this watershed includes urban, peri-urban and agricultural zones. The region relies heavily on a shared coastal aquifer and has a population of approximately 66,000 people in the Akrotiri area.

Almada Municipality (Portugal)

This coastal, flood-prone urban area south of Lisbon covers 70 km², combining densely populated urban and peri-urban zones with agricultural and fishing activities.. It is underlain by a vulnerable coastal aquifer that supports green spaces and local agriculture.

Nadhour Saouaf Watershed (Tunisia)

A 351 km² watershed located in a semi-arid region dominated by agricultural activities, with growing industrial development and rapid land use changes. Monitoring is limited, and the area supports a population of approximately 30,000.

Val di Cornia (Italy)

Spanning approximately 600 km² in coastal Tuscany, this pilot site includes riverine zones, wetlands (e.g. Orti Bottagone) and productive aquifers that are critical to agricultural and ecological systems. The area is prone to land subsidence and groundwater stress.
