This paper presents three spatial decision-support models (Boolean logic, binary evidence and overlapping index of multiple class maps) to perform a land suitability analysis for sanitary landfill siting. The study was carried out in the basin of Lake Cuitzeo, Mexico, with the objective of locating areas that comply with environmental regulations and with the inter-municipality criterion, i.e., that are accessible by at least two municipalities. Biophysical and socio-economic data were processed in a Geographic Information System (GIS). The three models differ in their complexity and restrictiveness. The Boolean logic model is easier to apply and more restrictive than the other two, because it is based on the assessment of single attributes. On the other hand, the binary data and overlapping index methods are relatively more complex because they require attribute weighting. The results showed that 23 of the 28 municipalities included in the basin have at least one area that was classified as highly suitable. The most suitable areas covered from 63.8 to 204.5 km(2) (from 1.5% to 5%), and they are not distributed homogeneously, but clustered around four main sites. The larger and most suitable of these sites is located in the central part of the basin, and it can be accessed by five of the most densely populated municipalities. The proposed approach represents a low-cost alternative to support a common spatial decision-making process in developing countries.

    ABSTRACT: The main aim of this study was to develop a procedure that minimizes the wasting of space for the siting of hazardous waste landfills as part of a solid waste management system. We wanted to tackle the shortage of land for waste disposal that is a serious and growing problem in most large urban regions. The procedure combines a multi-criteria decision analysis (MCDA) approach with a geographical information system (GIS). The GIS was utilised to obtain an initial screening in order to eliminate unsuitable areas, whereas the MCDA was developed to select the most suitable sites. The novelty of the proposed siting procedure is the introduction of a new screening phase before the macro-siting step aimed at producing a “land use map of potentially suitable areas” for the siting of solid waste facilities which simultaneously takes into consideration all plant types. The issue of obtaining sites evaluations of a specific facility was coupled with the issue of not wasting land appropriate to facilitate other types of waste management options. In the developed case study, the use of an innovative criteria weighting tool (the “Priority Scale”) in combination with the Analytic Hierarchy Process was useful to easier define the priorities of the evaluation criteria in comparison with other classic methods such as the Paired Comparison Technique in combination with the Simple Additive Weighting method.

    • "Such criteria were based on national and international codes related to site selection of a landfill and considering environmental, social and economic parameters. (Simsek et al., 2006; Baban and Flannagan, 1998), Kontos et al., (2005), Sener et al., 2006; Gemitzi et al., 2007; Delgado et al., 2008) Table 1. A large portion of the data came in the form of analog maps. "

    ABSTRACT: The exponential rise in the urban population of the developing countries during the past decades accelerated the urbanization phenomenon and the great need for solid waste management. This fact brought awareness of the necessity to develop efficient solid waste management systems in land use planning. Due to insufficient funds, poor planning and growing needs for solid waste management systems, many Egyptian cities dispose their solid wastes in open sites. In Sinai Peninsula, cities are located either on the coastal zones or in deserts. Motivated by the Government objective in developing the cities of Sinai, this paper tries to participate in finding a solution using a spatial multi-criteria decision support system for locating potential landfill sites for North Sinai cities. Criteria concerning three themes were combined to produce three scenarios. Environmental theme related to soil characteristics; permeability and groundwater as well as vulnerable land cover units, faults and streams. Economic theme includes slope, road network, and power lines. Social theme includes distance from airports, archaeology sites and land aspect. Prioritizing the weight of a specific theme or giving an equal weight to the three themes produced different scenarios. A suitability index map was produced for each case. Comparing the three suitability indexes; zones with the highest values were selected resulting in a set of candidate sites for each city in the investigated region. According to the characteristic of a location, a scenario could be preferred. More than an option resulted and are available to the decision makers according to their strategies and objectives.

    • "Environmental factors are very important because the landfill may affect the biophysical environment and the ecology of the surrounding area (Kontos et al., 2005; Sumathi et al., 2008). Economic factors must be considered in the siting of landfills, including the costs associated with the acquisition, development, and operation of the site (Delgado et al., 2008; Kontos et al., 2005). Social and political opposition to landfill siting have been indicated as the greatest obstacle for successfully locating waste disposal facilities. "

    ABSTRACT: One of the most important steps in solid waste management is the selection of an appropriate landfill site. The site selection process requires the evaluation and analysis of several criteria. However, the traditional evaluation method is not sufficient for the site selection process. Geographical information system (GIS) technologies are effectively used in the process of site selection, which is a spatial problem. This article describes a raster GIS-based landfill site selection (LSS) method. This method utilizes a raster-based spatial database in which the factors affect the landfill site selection. The final product in this method is the cost surface map showing pixel-based values of the appropriate areas. Furthermore, this GIS-based LSS method was applied for the evaluation of two landfill sites in Trabzon Province in Turkey, for which the traditional evaluation method for site selection was used. The suitability values on the cost surface map of these two landfills have shown that these sites are not appropriate for a solid waste landfill. In conclusion, it was demonstrated that the method of raster GIS-based site selection gives more effective results than traditional methods.
