Mapping Forest Landscape Multifunctionality Using Multicriteria Spatial Analysis

Abstract

This paper presents a GIS methodological approach for mapping forest landscape multifunctionality. The aims of the present study were: (1) to integrate and prioritize production and protection functions by multicriteria spatial analysis using the Analytic Hierarchy Process (AHP); and (2) to produce a multifunctionality map (e.g., production, protection, conservation and recreation) for a forest management unit. For this, a study area in inner Portugal occupied by forest and with an important protection area was selected. Based on maps for functions identified in the study area, it was possible to improve the scenic value and the biodiversity of the landscape to mitigate fire hazard and to diversify goods and services. The developed methodology is a key tool for producing maps for decision making support in integrated landscape planning and forest management.

Spatial Analysis of Risks and Vulnerabilities to Major Hazards in Madagascar Using the Multi-Criteria Method Based on the Analytical Hierarchy Process (AHP)

“…Multi-criteria analysis is a mathematical method to help decision-makers when faced with a complex problem that depends on several criteria of a qualitative or quantitative nature (Navalho et al, 2019). Several multi-criteria analysis models are developed that are differentiated by their aggregation processes.…”

“…This study shows the efficiency of the method used but the computerized implementation of spatial processing with this method still remains a prospect. Navalho et al (2019) carry out a comparative analysis of the current distribution of forest areas with multi-criteria spatial analysis using the analytical hierarchy process (AHP) integrating three factors (slope of the terrain, soil diagnostic characteristics and bioclimatic indices). The problem with spatial analysis is that the data are complex, heterogeneous and non-linear because the existing and geographical phenomena are characterized by their position, shape, descriptive attributes, topological relationships and formats according to their source (Chakhar, 2006).…”

A Design for Addressing Multiple Ecosystem Services in Forest Management Planning

“…Thus, the spatial pattern of fire ignition and spread across landscapes is affected by fire proneness, both characterized by GIS. Furthermore, a GIS-based AHP multi-criteria spatial analysis method was applied to integrate and prioritize production and protection functions of forests [64] and to determine cartography of the potential fire risk areas and phytosanitary risk maps [65]. Similarly, Eskandari [66] identified locations for fire ignitions on the basis of fire risk goal as well as the topographic, biologic, climatic, and human sub-criteria parameters used to model the fire risk with fuzzy membership AHP and GIS.…”
