This paper continues a line of research on improving strategic decisions (SD). The nature of governance
issues (complex and uncertain world, lack of information, consideration of qualitative and quantitative
information, participation of different actors in the decision making processes, etc.) implies that there
is no unique solution or strategy in a complex system. On the contrary, there are a range of alternative
strategies, which could lead to different futures (scenarios). Working with the qualitative methodology
proposed allows decision makers and social actors to be more aware of the directions their decisions could
lead the system; and what the key variables are for the implementation of public policies to achieve the
desired (or agreed) scenario. An integrated methodology is discussed, and the process of desertification
in the Canary Islands is used to illustrate it.
