“…In this study, a GIS-based MCDA approach was chosen to overcome this complexity since it is one of the most feasible ways to determine the vulnerable areas of mountain glaciers. Previously, different models were used to define the vulnerability of glaciers and successful results were achieved by these models [13,16,68]. The present study was designed to determine the spatial distribution of the vulnerability of the Agrı Mountain glacier and assess the forecasting capabilities of the GIS-based MCDA model for determining the zones of glacier retreat in order of priority.…”

“…Traditionally, glacier changes have been studied in many types of research using in situ measurements [4][5][6][7]. To date, a major part of the studies on this subject has been carried out using remote sensing techniques [8][9][10][11][12] and geographical information systems (GIS) [13][14][15][16]. With the recent developments in satellite and aerospace technologies, it is now possible for scientists to investigate challenging and extensive areas in a shorter time through remote sensing applications.…”

“…The future behavior of the Rutor glacier was simulated from 2005 to 2100 using climate scenarios [13]. Yang et al (2015) developed a glacial numerical model using remote sensing and GIS-based spatial principle component analysis on China's mountain glaciers. Nine factors were defined in the model as: slope, aspect, hillshade, elevation, air temperature, precipitation, glacial area change percentage, glacial type, and glacial area, describing topography, climate, and glacier characteristics.…”

“…Nine factors were defined in the model as: slope, aspect, hillshade, elevation, air temperature, precipitation, glacial area change percentage, glacial type, and glacial area, describing topography, climate, and glacier characteristics. The vulnerability of glaciers to climate change was evaluated on a regional scale in the period 1961-2007 and the 2030s and 2050s [16].An assessment of the vulnerability of glaciers to climate change provides the basis for scientific adaptation to glacial differences [16]. For this assessment, a set of factors must first be determined and then evaluated according to their importance [35]; however, it is very difficult to overcome the complexities of the phenomenon.…”

Investigating the causes of the spatial heterogeneity of glacial changes offers vital information about glacial behavior and provides forecasting ability to define where glacier retreat may occur in the future. This study was designed to determine the spatial distribution of Ağrı Mountain glacier vulnerability. The main goal of the current study was to assess the forecasting capabilities of Geographical Information System (GIS)-based Multi-Criteria Decision Analysis (MCDA) for determining the location of the mountain glacier retreat. To estimate the glacier retreat, the following criteria were selected: elevation, aspect, slope, direction, and glacier surface temperature anomaly (GSTA). The entropy method was used for weighting the criteria for the evaluation of the vulnerable areas of the glacier. The results of this method clearly indicate a strong relationship between GSTA, direction, and elevation criteria and glacier retreat. The glacier vulnerability map was created by synthesizing criteria layers with their weights. The vulnerability map provided a consistency of 77.8% in the short term and 92.1% in the long term. In the study, the priority melting zones were determined and glacial retreat locations were forecasted in 10-year periods.

The glacier is a crucial freshwater resource in arid and semiarid regions, and the vulnerability of the glacier change is intimately linked to regional ecological services and socio-economic sustainability. Taking the Tianshan Mountains region in China as an example, a basic framework for studying the vulnerability of glacier change was constructed so as to address factors such as physical geography, population status, socio-economic level, agricultural development, and social services. The framework was based on key dimensions, that is, exposure, sensitivity, and adaptability, and this constituted a targeted evaluation index system. We examined the spatial structure and spatial autocorrelation of the glacier change vulnerability using ArcGIS and GeoDa software. The influence and interaction of natural, social, economic, population and other factors on glacier change adaptability was examined using the GeoDetector model. The results suggested the following: (1) The vulnerability level decreased from the western region to the eastern region with significant differences between the two regions. The eastern region had the lowest vulnerability, followed by the central region, and then western region which had the highest vulnerability. (2) Significant positive and negative correlations were found between exposure, sensitivity, and adaptability, indicating that the areas with high exposure and high sensitivity to glacier change tended to have a low adaptive capacity, which led to high vulnerability, and vice versa. (3) The spatial heterogeneity regarding the ability to cope with glacier change reflected the combined effects of the natural, social, economic, and demographic factors. Among them, factors such as the production value of secondary and tertiary industries, the urban population, urban fixed-asset investment, and the number of employees played major roles regarding the spatial heterogeneity of glacier change.
