“…As stated in this paper, the AHP method "is applied in many and different research fields, including nature, economy and society". Recent applications of the AHP method in forestry involve, among other issues, forest road assessment [39], evaluation of non-wood forest products [40], analysis of forest fire risk [41], and ranking of indicators of sustainability [42].…”

The forestry sector in Chile has an important role in the domestic economy, being the second leading export sector after the mining industry. Investments in forest plantations have grown in the last 40 years thanks to implementation of the Decree Law 701. Planted forests currently account for 17.4% of the total national forest cover. The objective of the study is to analyse non-industrial forest owners' perceptions of positive and negative externalities of forest plantations in four less developed municipalities of the Maule Region. We implemented a literature review, the estimation of an Expert's Response Indicator (ERI), and the implementation of an Analytic Hierarchy Process (AHP) methodology for the analysis. The results indicate that non-industrial forest owners in the four municipalities perceive the importance of each externality in a different way according to their territorial specificities. However, considering the whole study area, "CO 2 sequestration", "improvement of livelihood", and "more importance of small and medium forest owners" were considered the most important positive externalities, while the most relevant negative externalities were "water shortage", "power asymmetry", and "land loss". The study encourages further research with a similar detailed analysis on stakeholders' perceptions of plantation projects, both to revise investment features and inform local stakeholders on their real impacts.

“…In addition, decisions can be considered from a strategic, tactical, and operational perspective and may vary depending on the organizational goals (Blagojević et al 2019). A variety of MCDMs have been applied in forestry to support decision-making relating to sustainable forest management (Diaz-Balteiro and Romero 2008;Kangas and Kangas 2005;Valls-Donderis et al 2017) road management/planning (Buğday and Akay 2019;Çalişkan 2017;Faramarzi et al 2021;Gumus 2017), assessing fire risks (Da Silveira et al 2008;Kayet et al 2020;Sari 2021), strategies for smallholder farmers (Stainback et al 2012;Thomas et al 2021;Zhang and Paudel 2021), machine selection (Perez-Rodriguez and Rojo-Alboreca 2012; Talbot et al 2014) and the development of models to assist in decision-making regarding forest operations (Ramantswana et al 2020a, b, c;Rönnqvist et al 2015).…”

Forest Owners Organizations can help small- and medium-scale private landowners stay competitive by conducting and sharing research and development (R&D) activities. This study evaluated R&D needs for silvicultural operations to inform an R&D strategy for the cooperative. Individual and group priorities were collected using the Analytical Hierarchy Process via a web survey and web meeting. Consensus in priorities was followed by an assessment of the cooperative's capacity to carry out in-house research. Two regional managers, eight plantation managers and one R&D/Technology manager participated in one or more stages of the process. Participants ranked most silvicultural operations similarly. However, the variation was largest for harvest residue, seedling, and stump management. Minor regional differences were found but both regions (south and north) had “very high” group consensus indicators (86.2% and 89%, respectively). The group decision ranked R&D in harvest residue management as the highest priority, followed by soil preparation and planting methods. The cooperative's strongest capacity for in-house research was in the execution of the experimental design to address the research questions (implementation). The weakest research capacity was found in terms of harvest residue, seedling, and stump management. Hence, the cooperative is dependent on research institutions. These findings can be used to inform and align the cooperative's R&D strategy, investments, and their research collaborations.

“…Of the various comprehensive evaluation methods, radar graph analysis method is a visualized multi-attribute comprehensive evaluation method that intuitively displays the relative superiority of the evaluation object in various indicators and make overall evaluation at the same time. It has the characteristics of simplicity, intuition, and strong operability [9][10][11][12], and has been widely used in forestry and environment studies [5,[13][14][15][16][17][18][19][20][21]. However, the radar plot used in these studies has one fatal defect-the non-uniqueness of feature vector area and perimeter caused by different ranking order of evaluation indicators [12].…”

Comprehensive evaluation of forest state is the precondition and critical step for forest management. To solve the problem that the radar plot and unit circle only focus on the value of each the evaluation index, this paper proposes a novel method for comprehensively and simultaneously evaluating the functionality and inhomogeneity of forest state based on the modified unit circle method. We evaluated the forest state of the Quercus aliena BL. var. acuteserrata Maxim. ex Wenz. broad-leaved mixed forest in the Xiaolong Mountains Forest Area of Gansu Province and the Pinus koraiensis Sieb. et Zucc. broad-leaved mixed forest in Jilin Province in China. According to the principle of comprehensive, scientific and operability, 10 evaluation indices on forest structure and vitality were selected to construct the evaluation indicator system. Each index was normalized based on the assignment method and ensured to be strictly positive based on reciprocal transformation method. The areas and arc length of the closed graph, formed by connecting every two adjacent indicators, in the radar plot and unit circle were extracted. Based on the isoperimetric theorem (isoperimetric inequality), a comprehensive evaluation model was constructed. Compared with radar chart and unit circle method, each index in the newly proposed unit circle method is represented by an independent sector region, reflecting the contribution of the index to the overall evaluation result. Each index has the same relative importance weight, contributing to the estimation the relative sizes of each aspect of forest state. The unique area and arc length of the closed graph help summarize the overall performance with a global score. The expression effect of improved unit circle has been enhanced, and as an English proverb put it, “A picture is worth a thousand words.” The new proposed method simultaneously evaluates the functionality and inhomogeneity of the forest state and it is a powerful tool for the diagnosis of forest state problems and the decision-making of forest management.
