“…The factor weights reflect the factors' importance for the decision-making process, and, the Participatory Technique is usually employed in their definition (Vettorazzi & Valente, 2016). In this study, decision-makers uesd the Analytic Hierarchy Process (AHP), developed by Saaty (1980) to obtain the factor weights.…”

“…According to the authors, PT is a meeting of experts who are named decision makers, who usually represent areas related to the specific study subject. Boroushaki & Malczewski (2010), Silveira et al (2014), and Vettorazzi & Valente (2016) defined criteria and weights through PT, adopting the final criteria and criteria-weight values that represented the group consensus.…”

“…It allows for identifying priority alternatives for the considered object (Francisco et al, 2008). Several authors have conducted area spatialization using MCE in environmental studies seeking to prioritize important areas for natural resource conservation and landscape restoration (Valente & Vettorazzi, 2008;Francisco et al, 2008;Silveira et al, 2014;Vettorazzi & Valente, 2016;Saito et al, 2016).…”

This study aimed to define potential areas for forest conservation to improve water quality, using Multicriteria Evaluation (MCE); and to verify differences between results from a multidisciplinary group of experts. We worked with the Pirapora River Watershed, Piedade/SP. The participatory method was used to identify the criteria and their relative importance. Priority maps representing expert opinion were elaborated, as well as a map with average weight values. We compared the differences between the criteria weight values and the maps of priority areas. The maps proposed distinct spatialization of priority areas, supporting the understanding of criteria that influence the decision-making process. The highest priority level was associated with areas near to springs, forest patches, and with the highest slope values. We concluded that the MCE is an efficient method to identify priority areas; however, the selection of an expert group is an essential step to generate representative analyses.

Urbanization process transforms original landscapes into an anthropic mosaic, causing impacts on hydrologic cycles and on landscape structure and functions. Aiming at the maintenance of the water resources and biodiversity, in an urbanized watershed, the objective of this study was the definition of priority areas for forest restoration. We used a Multicriteria Evaluation (MCE) method, following the steps: criteria definition, identification of the criteria importance, and criteria aggregation through Weighted Linear Combination (WLC). According to the experts, consulted in the context of the Participatory Technique, only two criteria represented the studied landscape: proximity to drainage network and proximity to forest patches. The first criterion was considered twice more important than the second, and through the pairwise comparison matrix, it was obtained respectively the criterion weights of 0.83 and 0.17. The priority map was obtained through the criteria aggregation, using WLC, that considered the criterion weights. The result was a priority map, indicating 5.06% of the study area with very-high priority for forest restoration; 5.22% with high priority; 5.76% with medium priority; 5,42% with low and; 78.53% with very-low priority. We can say that the framework predefined for the study proposed a scenario for priority areas that allowed driving the actions in order to obtain a landscape restoration, beginning through a forest corridor in the riparian zone. Thus, we concluded that the definition of priority areas for forest restoration is possible in an urbanized landscape, using the traditional WLC Multicriteria method. ANÁLISE MULTICRITERIAL PARA PRIORIZAÇÃO DE ÁREAS À RESTAURAÇÃO FLORESTALRESUMO: O processo de urbanização transforma paisagens originais em um mosaico antropizado, causando impactos no ciclo hidrológico, na estrutura e função destas paisagens. Visando à manutenção dos recursos hídricos e da biodiversidade, em uma bacia hidrográfica urbanizada, o objetivo deste estudo foi a definição de áreas prioritárias à restauração florestal. Utilizou-se um método de Avaliação Multicriterial (AMC), seguindo as etapas: definição de critérios, identificação da importância dos critérios e, agregação de critérios por meio do método da Combinação Linear Ponderada (CLP). De acordo com os especialistas consultados, no contexto da Técnica Participatória, apenas dois critérios representavam a paisagem estudada: o proximidade à rede de drenagem e o proximidade aos fragmentos florestais. O primeiro critério foi considerado duas vezes mais importante do que o segundo e, por meio da matriz de comparação pareada, foram obtidos seus pesos de critério, respectivamente, de 0,83 e de 0,17. Estes pesos foram considerados na agregação dos critérios, por meio da CLP. O resultado foi um mapa de priorização de áreas, o qual apontou 5,06% da área de estudo com prioridade muito alta para restauração florestal; 5,22% com alta prioridade; 5,76% com prioridade média; 5,42% com baixa e; 78,53% com prioridade muito baixa....

Geoprocessing tools are great allies in the management of water resources, with which it is possible to evaluate several factors integrated in a multicriteria analysis. This improves the interpretation of the behavior of water and soil in hydrographic basins, enabling the delimitation of priority areas for actions. The objective of this study was to prepare a map of priority areas for water conservation in the Alto Iguaçu basin through a multicriteria analysis, aiming to assist in the management of water resources in the region. The priority map for water conservation was prepared using the weighted linear combination (WLC) method, considering the weight added to the factors that were obtained by the analytic hierarchy process (AHP) method. The method successfully identified priority areas for water conservation, where 40.7% of the Alto Iguaçu watershed was considered high priority and very high priority, a number consistent with regional characteristics. The multicriteria analysis proved to be a flexible and easy‐to‐implement methodology, which can help managers when considering the trade‐offs among several factors. The implementation of water conservation actions in areas that have been classified as being of high and very high priority can benefit the regional ecosystem, controlling erosion, regulating the flow of water and thus conserving the quantity and quality of water in the basin and its downstream region, benefitting the population and regional economics.
