There are many previous studies that have dealt with the issue of
landfill site selection and tried to solve the problem of the landfill
locations in various ways according to the researcher specialization,

2.2 Literature review:


Name of the researchers: Mokhtar Azizi
Mohd Din, Wan Zurina Wan Jaafar and Wan Muhd Aminuddin Wan Hussin

In this study the researcher started by
identification of evaluation criteria or parameters needed for landfill siting. Besides, the related
information about landfill siting has also been reviewed from the international
practices like Environmental Protection Agency (EPA) from the United States
plus review from related literatures. All the data pertaining to these
parameters were taken from the relevant agencies, however not all parameters
are included in this study due to the lack of data availability. In his study
eleven (11) parameters have been identified for landfill site selection namely
surface water, residential area, railway, flood prone, swamp, archeology or
historical site, slope, soil type, land use, road accessibility and urban area.

2.2.2 Case 2: GIS and Multicriteria Decision Analysis for Landfill Site Selection in
Al-Hashimyah Qadaa


Name of the researchers:  Mohammad
Ali Alanbari, Nadhir Al-Ansari, Hadeel Kareem Jasim

In this study landfill site selection was performed by using
Multicriteria Decision Analysis (MCDA) and Geographic Information System (GIS)
for the Al-Hashimyahqadaa. MCDA was used to measure the relative importance
weighting for each critera. Each map layer was prepared using GIS and the final
suitable map was created by overlay analyses of each criterion map.


2.2.3 Case 3: Modelling
landfill location using Geographic Information Systems (GIS) and Multi-Criteria
Decision Analysis (MCDA)

Name of
the researcher: Solomon Peter Gbanie

This research
presents a methodological framework for identifying municipal landfill sites in
urban areas in Sierra Leone using Bo in Southern Sierra Leone as a case in
point. This framework involves a multi-criteria GIS approach that blends two
aggregation techniques: Weighted Linear Combination and Ordered Weighted
Averaging. The results show that 83.3% of the study area is unsuitable for
municipal landfill.

2.2.4 Case 4: Landfill site selection using
multi-criteria evaluation in the GIS interface: a case study from the Gaza
Strip, Palestine

Name of the researchers: Moustafa El Baba
& Prabin Kayastha & Florimond De Smedt

This study focused on the selection of new suitable
landfill sites in the Gaza-Strip using multi-criteria decision analysis (MCDA)
with help of the analytical hierarchy process (AHP) method.


Case 5: Landfill site selection using combination of GIS and fuzzy AHP,
a case study: Iranshahr, Iran.

Name of researchers: M Torabi-Kaveh1, R
Babazadeh, SD Mohammadi and M Zaresefat.

In this study the GIS was used to calculate and classify
the selected criteria and FAHP was used to assess these criteria weights based
on their effectiveness on selection of potential landfill sites. As a result, a
suitability map was prepared by overlay analyses and suitable areas were
identified. Four suitability classes within the study area were separated,
including high, medium, low, and very low suitability areas, which represented
18%, 15%, 55%, and 12% of the study area, respectively
