I researched a doctoral thesis in Geography / College of Education for Human Sciences, University of Basra (using geographic information systems to study housing unit fragmentation and its impact on infrastructure services in the city of Nasiriyah)
Production Maps of the phenomenon of residential fragmentation include all residential neighborhoods included in the study, based on field survey data and analyzed spatially and statistically within a geographic information systems environment so that we can reach a true scientific interpretation that leads us to understand the phenomenon of residential fragmentation and its size in the study area.
The thesis dealt with the phenomenon of residential fragmentation, which defines the division of a residential unit or piece of residential land into secondary parts that may be equal or unequal, which results in more than one residential unit for the same land area. In order to know the proportion of the phenomenon of residential fragmentation, a field survey was conducted for (43) residential neighborhoods, and they were The percentage of public residential retail is (44.1%), and this greatly affects infrastructure services in the neighborhoods of Nasiriyah city.
The thesis was concluded as a result of a field survey of the (43) residential neighborhoods included in the study, which contained (42,080) residential plots in their designed basic maps, of which (1,513) residential plots changed in use, that is, their function changed from the residential function to other functions, so the number became The plots under study are (38,033) plots, of which (2,534) are unconstructed residential plots, while the number of undivided residential units was (21,251) units, meaning they maintained their basic design without division or division. Finally, the number of subdivided residential units was (16,782) units. After division and division, its number became (34,394) units, and the total number of residential units, divided and undivided, and after division, reached (55,645) residential units for the year 2022 AD
