Abstract:
The decision making process leading to potentially contentious mine closure management options being adopted necessitates a collaborative procedure, where all concerned stakeholders participate in arriving at the final decision. This process needs to take into account different and sometimes conflicting attributes of the damaged ecosystem. In this study, application of a Group Decision Making (GDM) approach, which takes into account judgments by all the identified stakeholders in a comprehensible mathematical model, is illustrated through a hypothetical example of a mine closure planning process. For this purpose, fourteen technical and stakeholder-related attributes which influence evaluation in decision making were identified and divided into criteria groups in a hierarchical structure. This hierarchy can then be sent to the stakeholder groups to score both performance and importance of the attributes. A group version of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), which is a distance-based Multi- Attribute Decision-Making (MADM) technique, is used to rank the management options. Application of the proposed approach to the mined ecosystem example generates consensual relative closeness indices indicating the optimum post-closure land management option.
