Uncontrolled Urbanisation, Satellite Images, Landscape Metrics, Palm groves, Oasis Ecosystem


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.

Dr. Assoule Dechaicha, Department of Architecture, Faculty of Sciences and Technology, 8 May 1945 University, Guelma, Algeria

Doctor Assoule Dechaicha is a researcher at the University 8 May 1945 Guelma (Algeria). He was a researcher attached to the Laboratory of Design and Modelling of Architectural and Urban Forms LACOMOFA at the University of Biskra. In addition to his university lecturer activity, he is currently deputy head of the department of architecture at the University of Guelma, in charge of post-graduation and scientific research since 2015. He was also head of an architectural design office (BEAU), which carried out several architectural and urban development projects during the period 2000 and 2015.

His field of research is mainly focused on the study of oasis cities in the South of Algeria, and the problematics related to the protection and promotion of oases. Several oasis cities have been the subject of publications: the largest cities of the Lower Sahara in the South (Biskra, Ouargla, and Touggourt), the Oasis of Bou-Saada in the Centre, and the Oasis of Adrar in South-West Algeria. The questions highlighted are related to architectural sustainability, urban landscape planning, oasis landscape, and urban remote sensing.

Assist. Prof. Adel Daikh, Department of Architecture, Faculty of Sciences and Technology, 8 May 1945 University, Guelma, Algeria

Architect of formation with a bi-cursus (Algeria-France), my first professional mooring was made in the economic sector more particularly in the construction fields where I exerted as a technologist in architecture and construction on structuring projects in EPC, an experience which lasted one beautiful decade, after which I made my return in academic medium and the field of scientific research in 2016 at the conclusion of training in post-graduation concluded by the obtaining of the diploma of magister in 2015. Currently, I am working as an assistant and responsible for the team of the professionalizing course of "operational project management" in the Department of Architecture at the University of May 8, 1945, Guelma. At the same time, I am preparing my doctoral thesis in the science, urban planning field in the Faculty of Architecture and Urban Planning, University Constantine 3.
