Encouraged, often with restrictions, cautions regarding
resources required & avoiding duplication
Output: a set of qualitative scenarios characterized by
narratives and causal diagrams unfolding in time, combined,
for those aspects amenable to mathematical formalization,
with quantitative scenarios characterized by simulation models.
Approach: a continuous iteration between the building of the
qualitative scenarios and the simulation models, engaging
experts and stakeholders in the scenario-building exercise
and encouraging communication and dialogue between
these different actors.
In parallel, modelers produce quantitative
scenarios which provide numerical data,
and make possible a consistency check
of the storylines.
Scenario construction process and scenario findings more
directly connected to concrete actors and decision-makers.
Global scenarios give general direction and provide
perspective and a set of functional constraints for the
national and sub-national scenarios.
More local scenarios provide flesh and specificity to
exercise and demonstrate the diversity of situations
involved in water issues.
Suggestions re the approach?
