Stage 4: DEVELOPMENT OF THE ADAPTATION STRATEGY

Prioritization of adaptation measures based on the score they attained at Stage 3. The measures that gathered the highest scoring may be included in the local adaptation strategies of the municipalities

Stage 4: Development of the adaptation strategy

Evaluation of adaptation measures addressing decreased water availability and droughts

In the following table, the adaptation measures are prioritized based on the ratings provided in Stage 3 for the multi-criteria analysis (MCA). The total score for each measure is calculated as the weighted sum of the score to each criterion and the weight of the respective criterion.
The measures gathering the higher ratings may be included in the Local Adaptation Plan of the municipality.
