Nowadays, uncontrolled urbanisation is one of the major problems facing
Algerian oasis regions. The monitoring and evaluation of its landscape
transformations remain a key step for any oasis sustainability project. This
study highlights the evolution of spatial growth in the city of Adrar in
southern Algeria during the period 1986-2016 by establishing a Spatio-
temporal mapping and landscape quantification. The methodological
approach is based on a multi-temporal analysis of Landsat satellite images
for 1986, 1996, 2006 and 2016, and the application of landscape metrics.
The results show two opposite spatial trends: significant growth of built-up
areas against an excessive loss of palm groves. The landscape metrics
allowed the identification of a progressive fragmentation process
characterising the palm groves. Thus, the findings of this study show the
utility of satellite imagery and landscape metrics approach for monitoring
urbanisation patterns and assessing their impacts on oasis ecosystems.
