· Since this study considers undesirable output in the dynamic SBM model, the Tone and Tsutsui [16] (see Appendix 1) dynamic SBM model can be modified to include undesirable output. This model also can consider carbon sequestration in afforestation and introduce it as an exogenous variable into the model.

· Abstract. The computation of the slacks-based measure (SBM) super-efficiency requires two-stage computation. Moreover, the projection of the slacks-based measure super-efficiency (Super-SBM) might not be Pareto-efficient. The super-efficiency might be overestimated by Super-SBM. In the current paper, we will propose an
