Decisions on infrastructure investments in coastal areas and river deltas are complex because they directly affect the regional economy and ecology. Climate change makes the decision more complicated.
The long-term guarantee of fresh water with increasing salinity risks and climate change are a reason for more and more countries to review water management and land use and associated investment in coastal areas.
The goal is to develop a method that maps the patterns of certainties and uncertainties of the negotiating processes in policy formulation on freshwater availability over the long term.
The challenges arising from climate change on fresh water are surrounded by many uncertainties, while the economic dilemmas are large. The result of this project is a structured approach for dealing with (in)security and its monitoring.
