The Threshold of Urban Sustainability within the Traditional Cities: Traditional Alnajaf city as a case study

Abstract

Successful urban interventions in traditional cities must be thoughtful, accurate and wise intervention, so the research assumed that urban sustainability represents a contemporary development intervention that tries to regulate the performance of urban products (components - dimensions) in traditional cities within three factors which are, the right time, right place, and positive performance. The traditional Alnajaf city in Iraq was taken as a case study, morphologically; the general shape of the city was classified into five main parts and examined them with physical dimension that was depended on the concepts of sustainability threshold according to the descriptive data. From this analysis the research determined the right, time and place to achieve the best sustainable intervention. The research found that there is a variation in the level of sustainability in traditional Alnajaf city resulting from the different type of intervention at the level of the constituent parts of the urban fabric. Thus, it is possible to take advantage of the limits of urban sustainability (The Threshold) in creating a balance between the type of urban intervention and the needs of the original city to preserve the traditional cities, including traditional Alnajaf city.

“…These cities act as a catalyst for creating a liveable, safe, and attractive environment, making them important destinations for both locals and tourists. [17] In 2009, Verschoor presented his research on the visualization of new architectural constructions, reuse of existing structures, urban formations, and architectural schemes for outdoor environments. Urban designs play a crucial role in contemporary design strategies, especially in the 21st century.…”

Urban spaces as catalysts for collective memories: a study of events' influence

“…Even if unintentionally or ignorantly to his thinking at times, and at other times to his imagination, conscience, or feelings. Depending on the scale, duration, and setting of the event as well as the goals and priorities of the associated architects, urban planners, and stakeholders, the effect of events on architecture might vary [4]. Because the kind of event and its effects can vary depending on the civilization level of the era or one above it, certain occurrences can continue for several eras until they find a setting that accepts them.…”
