This paper shows the results of a study carried out on the central area of Irbid, Jordan in order to assess the effect of the modern urbanization process on the degradation and loss of the city’s heritage. This type of work comes as a result of the need to study the interaction between modern and heritage landscapes, which are in a direct physical contact with each other, and thus to address the problems facing sustainable development. This paper investigates a number of urban planning concerns that include: assessment of heritage/modern landscape compatibility, heritage building degradation, urban land use change and its role in the fragmentation and lack of connectivity between historic sites, visual pollution and the effectiveness of the existing urban system infrastructure. For each problem, a complete scientiﬁc analysis supported by a detailed mapping system is performed, resulting in recommendations for the necessary engineering solutions. Spatial analysis through GIS, e.g. 3D modeling, focuses on evaluating the current condition of the urban system near the heritage landscape. The paper presents important ﬁndings, such as identifying the impact of urban and infrastructural expansion, detected from historical aerial images at different epochs, on the historic center of Irbid. The study emphasizes the urgent need to solve the current problems related to the urban system, to achieve the vision of sustainability, which includes solving trafﬁc problems for improving system accessibility, and reevaluating the policies and regulations to achieve a balanced interaction between the heritage and modern landscapes within the city.

Introduction Between 1975 and 2000, the percentage of the population living in urban areas in developing countries grew from 27% to 40% (Brockerhoff, 2000). This increase in population is associated with urban and infrastructural expansion. City boundaries continue to expand, consuming more and more of rural areas, forests, heritage places and other important non-urban areas. The UN publication World Urbanization Prospects (United Nations, 2002) presents other facts about the severity of the challenge of international urbanization that is making urban management one of the most important challenges for the 21st century (Cohen, 2004). Understanding the change brought by urban development is critical to those who study urban dynamics and those who manage resources and provide services in these rapidly changing environments (Knox, 1993; Turner et al., 1993). The situation is more severe in developing countries where the fast pace of urbanization is mainly un* Corresponding author. Tel.: +962 53903333x4730.
