MCDM-GIS Based land suitability evaluation for Abattoir site: the case of Addis Ababa, capital city of Ethiopia

Abstract

Abattoir is one of the important urban functions that need a suitable site to be compatible with the surrounding geographic features. Cities that have increasing population size having one abattoir is difficult to be accessible for all; especially in the city of Addis Ababa. In Ethiopia, there are limited research efforts that address the land evaluation for Abattoir through the AHP-GIS approach in Ethiopia particularly in Addis Ababa. In this study, MCDM-GIS-based approach was used to map suitable sites for Abattoir in Addis Ababa, the capital city of Ethiopia. To select and evaluate the site; ten physical and social criteria were used. All factor maps were geo-referenced and reclassified according to their suitability based on norms and standards of abattoir site selection. Weights for each criterion were assigned based on the Analytical Hierarchy Process using a pairwise comparison matrix. After assigning weights, all criteria were combined (WLC) to get the most suitable sites for the abattoir, and based on the overlay result a thematic map of the selected potential sites was produced. From the total study area, about 17.7% were found as the most suitable potential sites and they were grumped as 10; and 1.7% was unsuitable for abattoir sites. Thus, decision-makers should give due attention to social, economic, and environmental norms and standards to select abattoir potential sites to improve the environmental sanitation, abattoir service delivery, and wellbeing of the society at large.

Key words: Abattoir, Potential site, GIS, AHP, Ethiopia.
