Abstract
With rapid urban expansion across Tanzania, there is a need to institute
steps to address factors and forms as well as impacts and challenges
associated with the observed trend. This study’s aim is to use spatial
urban landscape indices to analyze the spatial changes in urban forms,
patterns, and rates across 11 urban centers in Tanzania over a 30-year
study period (1990–2020). During the past three decades, urban lands
of 11 cities and town in Tanzania have grown by a total of 480 km 2 .
Leapfrog growth was found as the most dominant form of urban
expansion in Tanzania while Dodoma, the capital city of Tanzania, had
the highest rate of urban expansion when compared to all other
individual cities. The most robust and significant interaction of the
AWMLEI and MLEI was found in Kigoma, Arusha, Mtwara, Mafinga, and
Tunduma cities. In contrast, Mbeya agricultural city, Arusha the tourist
city, Tabora, and Geita Lake zone areas did show their own peculiarities
revealing an interesting spatial temporal variation in rate and form of
expansion. The outcome of this study reveals that the influence and
management of economic and socio-cultural opportunities will be an
effective tool for the determination of the rapidly expanding cities and
towns of Tanzania.
