Group Analytic Hierarchy Process Sorting II Method: An Application to Evaluate the Economic Value of a Wine Region Landscape

In the ongoing context of climate change, there is an increasing need to support decision-making processes in the domain of landscape planning and management. Suitable evaluation techniques are needed to take into account the interests of actors and stakeholders in shared policy decisions. An important methodological contribution to the field is given by the Multicriteria Decision Analysis (MCDA), due to its ability to combine multiple aspects of a decision problem with the values and opinions expressed by different Decision Makers. The present paper develops the “Group Analytic Hierarchy Process Sorting II method” (GAHPSort II), which aims to sort a group of municipalities included in the UNESCO site “Vineyard Landscape of Piedmont: Langhe-Roero, and Monferrato” (Italy) according to the economic attractiveness of the landscape. Extending the previous versions AHPSort I, AHPSort II and GAHPSort, the GAHPSort II optimizes multi-stakeholder evaluations on large databases by reducing the number of comparisons. Moreover, the GAHPSort II method is proposed as a novel spatial decision support system because it combines a set of economic indicators for landscape and GIS methods for aiding the Decision Makers to better understand the case study and to support the definition and localization of policies and strategies of landscape planning and management.

Assessing Nature’s Contributions to People by Jefoure Roads for Sustainable Management in the Gurage Socio-Ecological Production Landscape in Ethiopia

“Jefoure” refers to a traditional grass-covered road with households settled on both sides in the Gurage socio-ecological production landscape in Ethiopia. We assess Nature’s Contributions to People (NCP) on Jefoure roads for sustainable management. Data were collected using survey tools and orthophoto images, and they were systematically analyzed using qualitative and quantitative methods. The Jefoure roads are beyond transport networks and enhance the people’s quality of life. We identified 12 contributions of Jefoure roads from the reporting categories of material, nonmaterial, and regulating NCP. Over time, the contributions of the roads at different localities decreased due to socio-economic, cultural, and religious changes. Recent trends in infrastructural provisions cause the degradation of Jefoure roads and lead to a decrease in their value. Therefore, sustainable landscape planning and management are essential to preserve and enhance the positive NCP. This study indicates that roads do not solely generate negative ecological impacts, and planners need to work on designing versatile roads, particularly in landscapes where traffic flows are low. Indigenous knowledge has a significant role in bridging the past and future and needs to be integrated into landscape planning and management.
