“…This is based on the fact that such changes do not affect in a considerable way the performance attributes other than income. For instance, considering the sample land unit, for which its performance is illustrated in Tables 3 and 4, if pasture (which performs better in terms of income than any forest LUT) was established in the first time interval (0-10) instead of the final interval (21)(22)(23)(24)(25)(26)(27)(28)(29)(30), such trajectory change would not affect the total runoff produced during the full time span. The same can be said for the case of sediment and BOC.…”

“…In the assessment of these income values no discount rate has been applied, hence they are not expressed as net present values. In addition to [23] and the present study, those attributes have already been used as indicators of land performance on ESS in other studies ( [5,25]). Although, in general, information about any on-site performance attributes could be used as input data for BIOLP, in this specific case these five performance attributes were chosen since they are considered to be relevant for important ESS in the study area.…”

BIOLP is an Integer Programming model based on the Balanced Compromise Programming multi-criteria decision method. The aim of BIOLP is to determine how a set of land use types should be distributed over space and time in order to optimize the multi-dimensional land performance of a region. Trajectories were defined as the succession of specific land use types over 30 years, assuming that land use changes can only occur at fixed intervals of 10 years. A database that represents the Tabacay catchment (Ecuador) as a set of land units with associated performance values was used as the input for BIOLP, which was then executed to determine the trajectories distribution that optimizes regional performance. The sensitivity of BIOLP to uncertainty in the input data, simulated through random variations on the performance values, was also tested. BIOLP showed a relative stability on its results under these conditions of stochastic, restricted changes. Additionally, the behaviour of BIOLP under different settings of its balancing and relative importance parameters was studied. Stronger variations on the outcomes were observed in this case, which indicate the influential role that such parameters play. Finally, the inclusion of performance thresholds in BIOLP was tested through the addition of sample constraints that required some of the criteria at stake to exceed predefined values. The outcome of the optimization exercises makes clear that the phenomenon of trade off between the provisioning service of the land (income) and the regulation and maintenance services (runoff, sediment, SOC) is crucial. BIOLP succeeds in accounting for this complex multi-dimensional phenomenon when determining the optimal spatio-temporal distributions of land use types. Despite this complexity, it is confirmed that the weights attributed to the provisioning or to the regulation and maintenance services are the main determinants for having the land use distributions dominated by either agriculture or forest.

“…In particular, [9][10][11] report the application of IIPT to locate sites for afforestation. There are other MCDM that are also suitable for performing a per-land unit optimization, as is the case for IIPT.…”

“…For instance, afforestation of agricultural land typically leads to soil carbon sequestration, but also to a loss of monetary income. Some MCDM are applicable only to discrete problem instances (e.g., AHP [6], ELECTRE [7], PROMETHEE [8] and iterative ideal point thresholding (IIPT) [9][10][11]), while others are applicable to both discrete and continuous decision problems (most prominently, goal programming [12] and compromise programming [13]). The fundamental distinction between a discrete and a continuous decision problem is the number of alternatives from which the selection is made.…”

Comparison of Three Ideal Point-Based Multi-Criteria Decision Methods for Afforestation Planning

Three ideal point-based multi-criteria decision methods (MCDM), i.e., iterative ideal point thresholding (IIPT), compromise programming (CP) and a newly-proposed CP variant, called balanced compromise programming (BCP), were applied to the Tabacay catchment in Ecuador with the aim of finding a distribution of land use types (LUT) that optimizes regional land performance. This performance was expressed in terms of several conflicting on-site ecosystem services (ESS), namely water conservation, soil protection, carbon storage and monetary income. IIPT selects the best performing LUT on a per-land unit basis, that is the assignment of a LUT to a land unit is completely independent with respect to other land units. CP and BCP, on the other hand, aim at optimizing the integrated regional performance. These methods produce a LUT distribution that is as close as possible to the absolute optimal performance that would be achieved when conflict among ESS is not considered. In general, similar results were obtained with CP and BCP. This was not the case when the results produced by these two methods were contrasted with IIPT. For most ESS under consideration, CP and BCP produced balanced results that were closer to the absolute optimal values when compared to IIPT. We conclude from our results that, when optimization of land performance at a regional scale is at stake, CP-derived models emerge as the preferable option over IIPT, especially when balanced solutions are a requirement.

ELECTRE TRI-C, ELECTRE TRI-nC and THESEUS are recently proposed outranking-based multi-criteria sorting methods. The effectiveness of each method is here characterized by (i) its capacity for suggesting precise and appropriate assignments, (ii) the probability of suggesting imprecise assignments, and (iii) the probability of suggesting wrong assignments. We are also interested in studying to what extent the effectiveness of the methods is influenced by the number of criteria and categories, the cardinality of the reference set (in case of ELECTRE TRI-nC and THESEUS), and the way in which this set is chosen or populated. Our conclusions are supported by extensive computer experiments. The results underline the importance of (a) the number of reference actions and their distribution per category, (b) the number of criteria, and (c) the way in which the reference set is populated. These results help to identify contexts for which a particular method may be more appropriate.
