Multicriteria Decision Analysis and Group Decision-Making to Select Stand-Level Forest Management Models and Support Landscape-Level Collaborative Planning
Forest management planning is a challenge due to the diverse criteria that need to be
considered in the underlying decision-making process. This challenge becomes more complex in
joint collaborative management areas (ZIF) because the decision now may involve numerous actors
with diverse interests, preferences, and goals. In this research, we present an approach to identifying
and quantifying the most relevant criteria that actors consider in a forest management planning
process in a ZIF context, including quantifying the performance of seven alternative stand-level forest
management models (FMM). Specifically, we developed a combined multicriteria decision analysis
and group decision-making process by (a) building a cognitive map with the actors to identify the
criteria and sub-criteria; (b) structuring the decision tree; (c) structuring a questionnaire to elicit
the importance of criteria and sub-criteria in a pairwise comparison process, and to evaluate the
FMM alternatives; and (d) applying a Delphi survey to gather actorsâ preferences. We report results
from an application to a case study area, ZIF of Vale do Sousa, in North-Western Portugal. Actors
assigned the highest importance to the criteria income (56.8% of all actors) and risks (21.6% of all
actors) and the lowest to cultural services (27.0% of all actors). Actors agreed on their preferences for
the sub-criteria of income (diversification of income sources), risks (wildfires) and cultural services
(leisure and recreation activities). However, there was a poor agreement among actors on the subcriteria
of the wood demand and biodiversity criteria. For 27.0% of all actors the FMM with the
highest performance was the pedunculate oak and for 43.2% of all actors the eucalypt FMM was
the least preferable alternative. The findings indicate that this approach can support ZIF managers
in enhancing forest management planning by improving its utility for actors and facilitating its

Causality and Importance of Sustainable Forestry Goals: Strategic and Tactical Assessment by DEMATEL and AHP
This paper presents the combined use of standard DEMATEL and AHP methodologies in assessing a selected set of criteria for evaluating sustainable forestry goals. Creating a decision-making framework with two participating individuals (the authors of this research) enabled the comparison of individually obtained solutions with the aggregated solutions derived by two methodologies. The use of DEMATEL enabled strategic viewing of the causality relations among criteria and a limited indication of cardinal information (weights) about their importance. Different from DEMATEL, the use of AHP is considered a control mechanism in tactical decision-making situations such as the usage of standard multi-criteria methods for solving forestry-related allocation or selection problems. AHPâs role is to derive weights of criteria in a very structured environment based on assumption that criteria are independent and only their mutual importance is relevant for further decision-making. Individual solutions and aggregation schemes for creating group solutions are compared for both methodologies. Critical analysis is given for different aspects of their combined use when treating causalities and the importance of criteria in evaluations of long-term sustainable forestry goals
An Approach to Developing the Multicriteria Optimal Forest Management Plan: The âFruska Goraâ National Park Case Study
This paper proposes a decision-making framework that integrates Decision-Making Trial and Evaluation Laboratory (DEMATEL), Best-Worst (BW), and Ordered Weighted Averaging (OWA) methods in a forestry management problem. Namely, the application of the proposed framework has been shown in the case study area of the National Park âFruska Goraâ in Serbia. The decision-making problem included five criteria (biodiversity protection, wilderness protection, promotion of tourism, promotion of education function, and sustainable use of natural resources) and four alternativesâmanagement plans (âbusiness as usualâ, âeco-tourismâ, âprotection of natural ecosystemsâ and âuse of natural resourcesâ). The results were focused on proclaiming a winning alternative in a multi-criteria context and have been tested for the different risk attitudes: risk-prone, risk-neutral, and risk-averse. For the risk-prone scenario, the winning alternative was âprotection of natural ecosystemsâ, while the risk-neutral and risk-averse scenarios recognized âeco-tourismâ as the winning alternative. The same procedure can be repeated for many other forest management tasks that require multiple criteria setting and risk attitude analysis
Fuzzy AHP Assessment of Urban Parks Quality and Importance in Novi Sad City, Serbia
This paper proposes an AHP approach that utilizes the fuzzy extent model to prioritize five city parks based on their present quality and projected importance for Novi Sad City, the capital of Vojvodina Province, in Serbia. The study involved an expert evaluation of a set of eight criteria to identify the most relevant subset of criteria for a detailed park assessment. The park evaluation took into account uncertainties (fuzziness), the expertâs risk tolerance, and different levels of optimism and pessimism. The obtained results could serve when defining upcoming city plans and management agendas related to green areas in the city. The proposed fuzzy-based methodology can be extended to group decision-making scenarios by involving more experts and stakeholder representatives. The park weights obtained through the fuzzy AHP methodology described in this paper can aid city planners and politicians in the strategic allocation of financial, organizational, and human resources for parks

Using Analytic Hierarchy Process and Best–Worst Method in Group Evaluation of Urban Park Quality
The paper compares two multi-criteria methods, the analytic hierarchy process (AHP) and the best–worst method (BWM), in assessing criteria related to the quality of urban parks. The criteria assessed were accessibility, location, biodiversity preservation, park equipment, water elements, terrain configuration, cultural and historical value, and the presence of small architectural objects. Five decision-makers participated in the research, having expertise in urban greenery, urban forestry, environmental protection, landscape design, and cultural and historical heritage. The results of decision-makers’ evaluations were compared at individual and group levels after the application of three aggregation procedures: CRITIC, ENTROPY, and WGGM (weighted geometric mean method). Similarities in results, i.e., priorities of analyzed criteria after applying the two different decision support methods, indicated high consistency between experts during the cognitive evaluation processes. All applied aggregation schemes performed well and may be considered trustworthy in identifying the group solution. One of the conclusions is that either the AHP or the BWM can be efficiently used in evaluations of criteria for assessing the quality of urban parks if the members of a group are consistent, regardless of whether the consensus process is properly carried out before the decision-making process
