Implementing fuzzy decision making technique in analyzing the Nile Delta resilience to climate change

In terms of the importance of Egypt’s natural resources, the prominence of minimizing the risks and the significance of taking an action to adapt to climate change, a multi-criterion analysis (i.e. in ranking the effectiveness of adaptation strategy) was proposed and implemented. The strategy is fuzzy decision making technique (FDMT). Primarily, the literature was reviewed. A study area was chosen. The impact of sea level rise was investigated. The vulnerability and adaptation of the study area was examined. The vulnerability index of the Nile Delta was investigated. The vulnerability indicators of the study area were examined. The available techniques were investigated and the FDMT was chosen to be incorporated to the study area. The FDMT was studied and applied to the Nile Delta. It was found that this technique is suitable in evaluating situations that deal with ambiguity and vagueness, involve subjectivity, and imprecise information. It was thus concluded that fuzzy decision making technique enables maximum benefit from practical know-how as it takes into account several variables and it could perform “weighted merging” to influencing variables.
