Abstract

In all urban centers of the Tigray region and the nation as whole, there is inefficient urban land utilization and development. The bottlenecks in the supply of serviced land are caused by inadequate provision of infrastructure and services. Moreover, the government often provides arterial infrastructure, leaving the provision of secondary and tertiary infrastructure to individuals or private sector developers. As a result private sectors or individuals assembled raw land only. Land closest to the arterial infrastructure was developed causing ribbon or corridor development. Parcels further away from existing physical linear infrastructure are economically inefficient than those closest. Urban land utilization in Mekelle city in general and AdiHaki Dejen area in particular is inefficient due to lack of infrastructure provision and under regulation. Therefore, the objective the study was to evaluate the impact of physical linear infrastructure on urban land utilization and development in AdiHaki Dejen area. To do so, the research started by evaluating and analyzing the current condition of urban land utilization using primary and secondary data sources. ArcGIS was used to analyze the proximity of linear infrastructure to parcels. Then, ArcGIS SQL was used to identify and analyze parcels close to infrastructure and those that are further away. The study shows that poor land utilization and development are caused by poor road access, drainage line, water supply line, telecommunication cable line and electric transmission line and street light. Generally, the study concludes that the main problem of the study area is inadequate linear infrastructure provision and under regulation. So, parcels further away from existing physical linear infrastructure are economically inefficient than those closest. This result was used as base line for urban planners, land use planners and managers to use the application of ArcGIS in urban land use planning and utilization for economically efficient land development and management. Cite this Article Haftay Hailu G/Yohannes, Vanum Govindu, Amare Gebremedhin Nigusse..The Impact of Linear Infrastructure on Land Utilization using GIS.
