Abstract

Landscape planning is not only about material production, but also about the provision of other services. The conservation and enhancement of landscapes to ensure ecosystem services (ES) for the benefit of society is an important issue in the field of OR. The aim of this study was to gain experience on how a decision support system based on MCDA can be used in practice for long-term landscape management. We present a planning tool that integrates DEA, Fuzzy AHP and DP. As a first step, it was crucial to know the current state of the landscapes. To this end, we used DEA to assess the operational efficiency of landscapes depending on a specific region (landscape unit), considering land use, land cover and ecosystem condition. Knowing that the provision of EFP is site-specific and dynamic due to changing natural conditions and influences as well as various other socio-economic and political factors, decision-makers define alternative management programs/scenarios for each unit under consideration. In the second step, the management criteria were selected and evaluated by the stakeholders. The Fuzzy AHP was chosen as the preferred weighting method for comparing the programs for each unit. Once all the alternatives, criteria and weightings are defined for each alternative per unit, the next step is to create a DP network for each unit to forecast the evolution of the unit to the target state, which depends on the ES supply/demand ratio in the unit.
