Ornithological tourism is a distinctive tourism potential, because it conforms to the logic of environmental development, and it works for the protection of biological diversity, and as a partner of local communities who wish to develop tourism projects around the observation and the protection of birds. The research aims to try to discover the causes hindering tourism based on the observation of the Algerian nuthatch in the state of Jijel, and to find solutions that would value this tourism, in order to eliminate the seasonality of the tourism sector in the same region on the one hand and to promote environmental tourism through bird watching tourism on the other hand, as Finally, we reached specific steps in order to value this type of tourism, most notably raising awareness at the regional level and enhancing integration between bird protection, especially the Algerian nuthatch , environmental services and the tourism sector.

The objective of this work is to capture the evolution of the urban spot (land use) of the city of Annaba (Algeria), between 2001 and 2019, through the diachronic analysis of satellite images, remote sensing indices and geographic information systems.The City of Annaba, like Algerian cities, has suffered and continues to suffer the effects of rapid urbanization and high population growth, resulting in uncontrolled spatial expansion. Socio-economic development has raised the agglomeration of Annaba to the rank of a regional metropolis.The problem of urbanizable land due to physical constraints (the coastline on the one hand, and the plains, forests and mountains on the other), has forced the city to spread out, on its ecologically vulnerable coastal strip, but also to the detriment of fertile agricultural land, in order to meet the high demand for housing and public services. As a result, a phenomenon of conurbation is being produced, which is amplifying an urban situation that is already very difficult to manage.

Urban improvement is currently being considered as a new mechanism for improving the quality of life and the urban environment in residential areas as well as in the city as a whole. The process of intervention to improve the living environment is not necessarily to fight against the deterioration that can affect buildings and structures, but the improvement can be the result of those changes that affect the characteristics of society and the cultures of the population over time and through the succession of generations. We carry out the process of improvement each time with the aim of keeping pace with these changes and adapting the living environment to the new data or the new generation.Through this study, we aim to identify the impact of the urban improvement through the intervention on the city of Tebessa. Like Algerian cities, this city has experienced a deterioration of its urban fabric, which appears in the poor state of the buildings and the deterioration of the infrastructure, its inefficiency and overload, leading to a growing imbalance in the urban environment, and the resulting change in the urban characteristics of these areas, negatively affecting the social and economic characteristics of the population.
