In 1992, the World Heritage Convention became the first international legal instrument recognize cultural landscapes as a human heritage that must be protected. The Cultural Landscape - Past, Present and Future considers different aspects of man's intervention with natural vegetation and the landscape resulting from a long equilibrium of co-existence. These landscapes are not stable, and the recent and ever accelerating changes in technology and life-style have increasingly affected many ancient landscapes, as old land-use practices are abandoned and traditions forgotten.(Birks et al., 1988) Human communities in desert areas formed a special landscape, providing these cultural landscapes within a special ecosystem of sustainable living conditions, which helped to create many social, economic, and cultural systems in addition to preserving biodiversity. Unfortunately, the cultural landscape in the African desert is constantly deteriorating under the influence of urban, economic, and social changes. In the southern Algerian Timimoun city of is one of the most important global desert touristic destination due to the natural cultural landscape characterizes it, but unfortunately this landscape in continuous deterioration. Agricultural landscapes of desert environment, with its remarkable knowledge culture and world of practices, must be seen as a living library where this knowledge is transferred from generation to generation. It seems certain that we will need more of the know-how stored in this living library in the near future, especially considering the effects of climate change we are experiencing today. The paper aims to identification of cultural landscapes in the oasis and analyses transformation and change in cultural landscape and traditional green infrastructure elements by relying on a historical analysis of spatial images based on quantitative analysis using ArcGIS software with the aim of identifying the real reasons of this deterioration in the urban cultural landscape in desert cites we will propose an action strategy to prevent this degradation.
