Summary
This study integrated analytical hierarchy process (AHP) and geographic information system (GIS) for marble waste disposal site suitability. Water bodies and agricultural land are top priorities for protection against marble waste hazards.
Area of Science:
- Environmental Science
- Waste Management
- Geographic Information Systems
Background:
- Marble waste poses significant environmental and social challenges in the Mohmand marble zone, Khyber Pakhtunkhwa, Pakistan.
- Current disposal practices involve indiscriminate dumping in open spaces or water bodies, leading to ecological degradation.
- There is a critical need for a systematic approach to identify suitable sites for marble waste collection and disposal.
Purpose of the Study:
- To assess site suitability for marble waste collection and disposal using an integrated AHP and GIS approach.
- To minimize environmental risks and address public and governmental concerns associated with marble waste.
- To develop a decision-making framework for sustainable waste management in marble industry areas.
Main Methods:
- Land use classification into environmental, social, and economic categories, with six sub-classes.
- Application of the Analytical Hierarchy Process (AHP) for pairwise comparison and weighted sum analysis.
- Utilized Geographic Information System (GIS) tools, including digitization, buffering, and overlay, for spatial analysis and integration.
Main Results:
- Identified priority land use classes for protection against marble waste hazards: water bodies (32.33%), agricultural land (30.50%), and settlements (12.16%).
- Established a priority sequence for land use protection: water bodies > agriculture > settlement > marble industries > road > cultural site.
- The integrated AHP-GIS model effectively determined optimal sites for marble waste management.
Conclusions:
- Water bodies and agricultural lands require the highest level of protection from marble waste.
- The integrated AHP and GIS model provides a robust and effective tool for site suitability assessment in waste management.
- Decision-makers can utilize this model to implement sustainable marble waste disposal strategies, mitigating environmental and social impacts.

01:21Manipulation and Analysis
85
GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

196
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

01:25Selected Data About Geographic Locations
84
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

In the past, planning projects such as schools or public facilities required extensive manual effort to gather and compile data. Information such as property boundaries, soil characteristics, road networks, zoning regulations, and flood zones had to be sourced individually from courthouses, utility providers, and registry offices. Assembling these datasets into a coherent format often took several months, delaying project timelines.The introduction of Geographic Information Systems (GIS)...

Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...
