Yasuni Deliberation Matrix


KerDST is an on line tool offering users a multi-stakeholder multi-criteria deliberation framework that can be applied to any situation of choice or debate as explained in the KerDST user’s manual (Bureau et al. 2007).


The deliberation matrix allows the analysis among the three elements, represented in three matrix axes and showed in the figure below:


  • Solution options for the social problem that are seen as possible futures or scenarios.
  • Scenario options that are evaluated through the performance issues or values.
  • And the judgement of values made by the actors concerned in the social problem (made by myself in this exercise) about present or future situations.

Moving beyond this first level framework, the online KerDST also integrates two major features within the multi-stakeholder, multi-criteria evaluation framework.

These are the mobilisation of indicators and the accommodation of multiple participants as members of the deliberations community.


This non participative experience uses variation A (without indicators) and variation C (with indicators) of the four variations of KerDST[1].

Figure 8. The four Variations of KerDST (Reichel et al. 2007)



Principal information for indicators found in KerDST includes:


  • Number of utilisations

     It’s the number of times the indicators was chosen to give a judgement.

  • Average Weight

     It’s the average of importance given by each participant to each indicator in percentage.

  • Global impact

     It represents the frequency of utilisations and at the same time its relative weight in each cell.

Evaluation of the case study: Multi-criteria evaluation of "Leaving fossil fuels in the ground as a social choice problem in Yasuní ITT (Ecuador)” is available on line in the KerDST site: http://kerdst.kerbabel.net/?q=node/448/matrice/364/view.

[1] THE FOUR VARIATIONS OF KERDST[1] include the participative approach variation B (without indicators) and variation D (with indicators). More information is found in many REEDS documents, including the KerDST Users’ Manual for the four variations made by Reichel et al. (2007).
