Gis-Based Multicriteria Decision Making Analysis For Abattoirsite Selection In Shashamane Town, Ethiopia

Abstract

Abattoirs are one important urban functions that need suitable site to be compatible with the Surrounding geographic features. However, they are observed being located at in appropriate site posing environmental hazard to their surrounding and are additionally influenced by some adjacent activities. The present study was conducted to find the most suitable abattoir site in shashamane town. In order to do this it was discovered essential to experience the national urban planning establishment of Ethiopia, and thus reviewing the experience of urban land use planning for sitting basic environmental issues like abattoir.An integrated Remote sensing and GIS approach was observed to be extremely useful to assign abattoir site in the study area. Factors that were found to be significant in distinguishing the site in the study area were; land use/cover, elevation, slope, streams, distance from the roads, distance from the high tension lines, distance from social services, distance from industrial areas, and boreholes. These factors were weighted in hierarchical order using MCE approach to produce the suitability map of abattoir site. From the overall suitability map, suitability level of areas was calculated. Major findings of the study revealed that, 12.46% of the study area covers a highly suitable area of abattoir, 22.91% area is suitable, 16.70% of areas is moderately suitable and the unsuitable area covers 47.93% of the study area. The highly suitable areas are mainly located in the south west, west and north of the study area. These areas falls in bare land uses. The suitable areas are located near the periphery of built up areas. Finally, the unsuitable areas site are located in the developed part of the town. Generally, locating the abattoir within highly suitable area can ensure minimizing the impact of abattoir on the surrounding environment in the form of liquid wastes,solid waste,airborne wastes and noise : reducing the impact of nearby activities on the abattoir through dust and smoke emitting industries.
