The
present work proposes an operational approach to the concept of Water-Ecosystems-Food
Nexus, based on the integration of Participatory System Dynamics Modeling techniques
(PSDM) and hydrological modelling, specifically the Soil and Water Assessment
Tool (SWAT). Specific reference is made to the Tarquinia Plain area (Central
Italy), one of the pilot areas within the LENSES project (PRIMA Foundation, GA
n. 2041), where irrigated agriculture plays a vital role for local communities,
yet with increasing concerns for the impacts on the state of the environment
and for the interplay with water resources availability (due to climate change
impacts) and quality. In summary the proposed approach is based on the use of:
i) Causal Loop Diagrams (CLD) for an improved conceptual understanding of
system state and potential evolution, as well as for the identification of key
challenges and leverage points; ii) hydrological modelling (SWAT) for getting a
deeper understanding of the main implications of agricultural practices on the
state of the area; iii) stock and flow models, for scenario analysis and policy
design. The methodological approach is being replicated in several case studies
in Europe and beyond.
