ASSESSING SOLID WASTE MISMANAGEMENT IN TRIPOLI, LEBANON, USING GIS: A SPATIAL ANALYSIS WITH THE SWEPT MODEL

Abstract

This paper presents an in-depth analysis of solid waste management in Tripoli, Lebanon, using the SWEPT model a suitability model incorporating multiple criteria to assess potential sites for recycling and waste management initiatives. The SWEPT model considers socio-economic factors, waste characteristics, environmental pollution, and topographical conditions, assigning each location a suitability score that ranges from unsuitable to very high suitability. The model allows for a comprehensive evaluation of potential sites for recycling and waste management infrastructure in Tripoli, taking into account the complex urban and socio-economic conditions that affect the city's waste management system.

In Tripoli, urban planning issues are exacerbated by a combination of factors, including high poverty rates, economic crises, water and river pollution, insufficient infrastructure, and mismanagement of vital facilities. These challenges are compounded by the city's inadequate waste management system, which struggles to meet the growing demands of its population. The SWEPT model helps identify areas that are most suitable for the establishment of recycling sites, based on a combination of criteria that consider both the environmental and socio-economic aspects of waste management.

The model's validation is achieved through a matrix analysis, which compares the suitability of the selected sites for recycling with existing waste collection points. This approach ensures that the chosen sites are both strategically located and viable for implementation. By integrating GIS technology and spatial analysis, the study provides a clear visualization of the relationships between various urban planning challenges and waste management issues in Tripoli. Through these analyses, the paper offers evidence-based recommendations for improving waste management practices, enhancing the city's infrastructure, and addressing broader environmental concerns.

Ultimately, this study seeks to provide a comprehensive understanding of the urban planning challenges facing Tripoli, Lebanon, and proposes actionable solutions to improve the city's solid waste management system, contributing to a more sustainable urban environment.
