Isonzo / Soča river basin

  • The Isonzo River (Soča in Slovenian) is a transboundary river. It originates in the Alpine Trenta valley (Italy) at an altitude of 935 and flows into the Adriatic Sea, with a delta near Monfalcone (Italy).
  • The Isonzo catchment basin subtends a total area of approximately 3400 kmsq of which is about 1150 Kmsq, that is about one third, in Italian territory;
  • The basin is prone to floods.
  • Main pressures on water resources from both countries are agriculture and hydropower with significant concerns over the impact of climate change.
  • The basin is prone to floods. The safety of the whole basin depends on the management of large Slovenian dams, but current transboundary flood prevention agreements are insufficient.
  • Although several bilateral agreements between Italy and Slovenia (e.g., Osimo agreement, 1975) facilitate cooperation, a shared framework for managing the whole basin with a specific focus on Nexus issues and taking into account climate change, which is threatening the viability of current agreements, is critically missing.
  • Main pressures on water resources from both countries are agriculture and hydropower, with significant concerns over the impact of climate change.
  • Local authorities (responsible for flood management, civil protection and policy): Friuli Regional Authority, Friuli Region Civil Protection
  • ISPRA (Italian National Institute for Environmental Protection and Research
  • Water authorities (responsible for flood management, water policies development): AAWA, Friuli Regional Authority
  • Environment Agency (Arpa FVG), Environmental authority in Slovenia (ex ARSO), Drainage authorities;
  • Energy authorities (responsible for the management of dams)
  • Farmers associations
  • Analyse the status of the actual management plan in relation to projected climate changes.
  • Find and test best solutions and best practices to guarantee future sustainability.
  • Find an equilibrium between different uses of water along the Nexus (flood/food/energy).
