“…Several softwares, including ERDAS Image 2015 and ArcGIS 10.3, were used to do this. According to [29], one of the most accurate elevation data that is currently freely available is derived from the Shuttle Radar Topographic Mission (SRTM), a Digital Elevation Model (DEM) dataset with 12.5 m spatial resolution. On the Open Street Map website (https://www.openstreetmap.org), road data were downloaded.…”

Environmental degradation is one of the most visible problems in Hargeisa. Currently, solid waste is disposed of at two dumping sites within the city limits causing nuisance and unsanitary conditions. Moreover, the existing dumpsites are on the verge of closure, therefore necessitating a dire need to be addressed. This research paper is aimed to integrate multicriteria decision analysis and GIS for evaluating the site suitability for the landfill in Hargeisa, Somaliland. For this purpose, eleven significant parameters were selected: proximity from built-up areas, surface water, groundwater well points, sensitive sites (Airports), land use/land cover, geology, soil type, elevation, slopes, roads, and distance to existing dumpsites. These were then integrated using an analytical hierarchy process (AHP). Subsequently, restriction buffer analysis was performed on the seven parameters to obtain better and more accurate results, and restricted zones were omitted. Furthermore, the pair-wise comparison used to obtain priorities between the selected criteria showed that the land uses land cover is the most significant criterion in the model with a relative weight of 0.1829, followed by the habitations, 0.1506. The overall result reveals that about 68.96% (21060.9 ha) of the study area is unsuitable, while 24.36% (7441.53 ha) and 6.68% accounted for the less and highly appropriate zone, respectively. Following the results of this study, Hargeisa City's municipal council must reconsider the waste management and landfill sites to solve the problems observed in the area before it is overdue. Furthermore, this systematic research approach will assist regional and global researchers, policymakers, and municipal governments.

“…Siting a landfill is an intricate and time-consuming practice, and for suitable site selection, a proper assessment method should be prepared [26]. Recently, Dolui and Sarkar [35] integrated multicriteria evaluation modeling and GIS systems to identify potential landfill sites for MSW disposal of Kharagpur city in eastern India. The study used AHP, Fuzzy AHP, SRS, and RSW weightage techniques for spotting alternative sites considering the social, environmental, and economical aspects.…”

“…Appropriate waste management is essential for accomplishing many United Nations' Sustainable Development Goals (UN' SDGs) [176] such as SDG6 "Clean Water and Sanitation," SDG11 "Sustainable Cities and Communities," and SDG12 "Responsible Consumption and Production" [56,121]. However, proper waste disposal and management are severe problems across the world [35,106]. Eriksson et al [41] documented that the production of a huge amount of MSW is a concern to the industrialized nations.…”

The burgeoning population has endangered the sustainability of urban areas where over half of the total global population will live by 2050. The population growth has increased the rate of waste production noticeably during the recent past. And its disposal and management are a serious environmental problem across the world. The problem is severe in developing nations because of the quick populace rise and urbanization, the absence of funding and policies, and poor and irregular waste management services. Besides, most municipal authorities in developing nations mainly focus on waste disposal and not management. Appropriate management of municipal solid waste (MSW) is essential for accomplishing many United Nations' Sustainable Development Goals (UN' SDGs) such as SDG6 "Clean Water and Sanitation," SDG11 "Sustainable Cities and Communities," and SDG12 "Responsible Consumption and Production." This paper assesses the use of diverse systems engineering models and remote sensing, GIS, and GPS for appropriate disposal and management of MSW issues. All the possible sources of related and up-to-date literature have been accessed and more than 210 publications were collected and thoroughly analyzed for this review. The past literature analysis revealed that the cost-benefit analysis models were used to appraise a waste management system's positive and negative economic effects. In contrast, optimization models were used to reach the best solution among several options, considering a set of objectives. The analysis also revealed that the GPS applications were primarily done for tracking waste bins and collection vehicles for monitoring collection time and location. Moreover, the investigation revealed that the combined applications of GPS and GIS techniques performed better than their specific applications. The analysis of numerous global case studies disclosed that political, socioeconomic, hydrological, geological, and environmental factors should be taken into account for a proper landfill siting.

“…Also, landfill locations were identified using a multi-criteria method, which was integrated with GIS and AHP methods (Nima et al, 2020;Michael et al, 2020;Sanu and Sarkar, 2021). This process is comprised of several predetermined criteria, such as distance from roads, railway lines, and agricultural land, altitude, protected areas, and water sources.…”

The absence of a landfill has increased the illegal waste disposal sites in Malaka Regency, which was established between 2013 and 2021. Therefore, this study aimed to analyze suitable and available land for the development of a landfill. The methodology used consisted of 2 analysis steps, namely land suitability and land availability. Land suitability was analyzed using a multi-criteria decision-making method, which included the slope, stone type/geology, lithology, soil type, soil texture, soil depth, soil drainage, distance from settlements, and water sources. The criteria were then weighted using the Analytical Hierarchy Process (AHP) and geographic information system for overlaying. Furthermore, the results of the land suitability analysis were used to determine its availability with the aid of spatial and regional planning (RTRW), land use, and forest area maps. The results showed that the highly suitable (S1) and available terrain for the landfill in Malaka Regency covered an area of 203.37 ha or 1.73% of the regency. Also, the analysis results indicated that there was still adequate land available for the landfill.
