Abstract :
The issue of spatial spread remains topical in
any society, especially in cities. Today, cities are
expanding at an exponential rate towards their
peripheries under the influence of a set of factors
including urban growth. African cities, and particularly
Cameroonian cities, are characterized by their strong
spatial growth. This situation is mainly due to the strong
growth of the population but also the multiplication of
human activities. It is in the light of this observation that
we have oriented our research on the monitoring by
remote sensing of the spatial spread of the city of Douala
in the era of urbanization. The objectives are to analyze
the spatial spread of the city of Douala, to identify the
factors at the origin of the spatial spread, the
consequences and the analytical tools. To achieve this
objective, we started from the general hypothesis
according to which the sprawl of the city of Douala is
linked to demographic growth, the development of
buildings, economic activities, etc. We have, of course,
relied on documents to approach this study, but most of
the work has been done in the field where direct
observation, etc. were effective tools for the outcome of
this research. Landsat’s images and shape files were also
used etc. Results from our field investigations show that
the city of Douala experienced strong spatial growth
between 1975 and 2019. In 1975, we note that built-up
areas represented 2.40% of the total area of the city of
Douala. In contrast, forest represented 84.47% and crops
1.53% of the study area. In 2007, built-up areas
represented 9.96% of the total area of the study area. On
the other hand, the forest represented 79.09% of the
studied area. In 2019, buildings made up 21.31% of the
city of Douala, forests 58.69%, crops 8.56% and rivers
11.44%. The sprawl of the city of Douala is linked to
various factors: the development of economic activities,
the development of communication routes, the
administrative center etc. The consequences among
others are the development of precarious neighborhoods,
the difficulties of access to basic urban services, the
reduction of arable land, etc.
