GIS-Fuzzy DEMATEL MCDA model for the evaluation of the sites for ecotourism development: A case study of “Dunavski ključ” region, Serbia

Ecotourism is now the fastest-growing sector in the Himalayan region as well as in the Garhwal region (Uttarakhand, India) as it has negligible adverse impacts on the environment and natural resources than tourism. Ecotourism plays an important role in the protection and sustainability of natural resources. Thus, the present study attempts to identify potential ecotourism sites using the analytic hierarchy process (AHP) and Geographical Information System-Remote sensing (GIS-RS) techniques in the Garhwal Himalayan region. The study is based on the use of GIS-RS used parameter concerning landscape naturalness, climatic characteristics, topographic attributes, accessibility parameters, reserved and protected areas, and natural attractiveness using a weighted overlay method in the GIS platform. We also used expert knowledge to assign weights and then normalized them by AHP eigenvector. We used the receiver operating characteristic curve for validation, which indicates the methods are very useful in ecotourism potentiality. The results show very highly, and the highly suitable area is about 21.12%, wherein 17.40% located in the greater Himalayan region. Areas adjacent to the densely forested areas, where snow-out occurs every year, develop various grasslands, cool climate, U and V-shaped valleys, very attractive landscapes sites suitable for ecotourism, but not for all seasons. The moderately suitable areas confined in the lower dissected valleys and upper snow-covered areas and make up about 26.04% (8456.68 km2) of the region. This study can help tourism planners and the government select locations precisely and further develop ecotourism activities and release pressures on the tourism burden in the region. The results have implications for sustainable tourism and ecotourism efforts of the United Nations Sustainable Development Goal-15 (SDG-15) of improving life on land by preserving natural heritage, wilderness areas, and culture. It can help the employment generation of the local people and direct profits to the local communities.

Land evaluation and sustainable development of ecotourism in the Garhwal Himalayan region using geospatial technology and analytical hierarchy process

The aim of this study is to identify potential ecotourism site using analytical hierarchy process (AHP) and geographical information system (GIS) in Kullu District, Himachal Pradesh, India. For this analysis, 13 elements such as slope, topographic roughness, vegetation, surface water accessibility, elevation, protected area, climate, visibility, road proximity, village proximity, soil, groundwater and geology have been taken into consideration. Required spatial data and information were collected from satellite imagery and available maps. AHP is widely used to provide criteria and class weight, and GIS is effectively used for the identification of ecotourism suitable zone. The result reveals the fact that out of total geographical land of the district 41% area is considered as high to very high suitable zone for ecotourism site development.

Site suitability analysis for green space development of Pendik district (Turkey)

Urban green spaces are important components, contributing in different ways to the quality of human well-being. In the planning and management of urban centres, attention to the appropriate site selection of urban green spaces with regard to the importance that these spaces have from the perspectives of ecology, socioeconomic, mentality, etc., is an inevitable requirement. In present decades, land suitability mapping methods and GIS have been used to support urban green space planners in developed countries; however, its application and practices are limited in developing countries, like Ethiopia. Therefore, the aim of this study has to select potential sites for green spaces in Sululta town that assist an effective planning process of green areas in a sustainable way. In this study, GIS-based Multi-criteria analysis (MCA) has been adopted to select suitable sites for urban green spaces. Existing land use, proximity to settlement, road and water body, population density, land ownership, topography, and scenic attractiveness were recognized as the key factor affecting urban green land suitability. The results showed that 13.6%, 34%, 28%, and 18.9% of the study area are highly suitable, suitable, moderately suitable, and poorly suitable, respectively, for urban green spaces development. Furthermore, out of the total area of the study town 5.5% of the landmass is not suitable for urban green spaces development. Therefore, the application of GIS-based MCA has provided an effective methodology to solve a complex decisional problem in urban green spaces site selection in the study town and urban planning all over the country.

GIS-based multi‐criteria analysis for sustainable urban green spaces planning in emerging towns of Ethiopia: the case of Sululta town

|In this paper, electromagnetic scattering from multi-impedance body of revolutions (BORs) is formulated using self-dual integral equations (SDIEs) and is solved numerically by the method of moments using BOR basis functions. Using the axial symmetry advantage of BORs, a 3D problem is converted to a 2D one, and a signi(cid:12)cant reduction in unknowns is obtained. This in turn leads to an increase in the speed of scattering problem solving. Numerical results show that monostatic and bistatic RCS calculation with the proposed method is about 85 and 18 times faster than the commercial software, respectively.
