AB  - Rapid population growth integrated with poor governance and urban planning is 
      highly challenging resulting key for the selection of unsuitable landfill sites, 
      particularly in developing counties. Therefore, the aim of this study is to 
      investigate the suitable solid waste landfill sites in the capital of the country 
      as a case study, by the integration of Geographical Information System (GIS) with 
      fuzzy logic, analytical hierarchy process (AHP), and weighted linear combination 
      (WLC) method based on multi-criteria decision-making (MCDM). We chose thirteen 
      (13) criteria (9 factors and 4 constraints) and grouped them into two main 
      categories (environmental and socioeconomic) to achieve the objectives. The AHP 
      was employed to evaluate the relative importance of the factors followed by 
      standardization of criteria factors based on fuzzy set theory. Subsequently, all 
      criteria factors were combined based on AHP and fuzzy logic-WLC method in order 
      to obtain land suitability map. Finally, the sites were identified by the 
      intersection of two combined suitability index layers. The obtained results 
      depicted that the integration of fuzzy logic, AHP, and WLC technique with GIS can 
      produce satisfactory results for the suitable locations of solid waste landfill 
      sites over complex topographic regions. Overall, the land suitability obtained 
      based on fuzzy-WLC is more refined and smooth because of its better segregation 
      and its potential to consider full tradeoff between factors and average risk. The 
      AHP was identified (47 km(2)) as high suitable while fuzzy-WLC generated 36 km(2) 
      as suitable area. Finally, the intersection of both suitability index map shows 
      numerous suitable landfill sites available in Islamabad city; however, the 
      surface areas of the sites are small at individual level (less than 15 ha).
