An international symposium entitled «Sustainable cities and local development» will take place on the 9th, and 10th of December 2019 at Guelma university, organized by the department of architecture. Through this symposium, researchers from all disciplines will be regrouped in order to promote research and developmental activities in urban development. Another goal is to promote scientific information interchange between researchers, developers, students, and practitioners working in and around the world revisiting the requirements of the sustainable city, from the new theoretical axes and the methodological innovations to the different approaches used in the attempt to combine urban development, built heritage safeguarding and the respect of environment.

 The symposium will be held to make it an ideal platform for people to share views and experiences in the related areas. This with the major concern of establishing the sustainability measures at a local level, because any operation or local development action is the fruit of a planning ambition with multiple intentions that could be political, social, economic, touristic, ecological, and others. However, the realization and success of a development operation implies the combination of several factors with multiple logics, different from that of an ordinary development operation, regarding the extent of the expected results and the scale of change.

Therefore, to take a new look at the dynamics of the local development associated with the sustainable city requirements is first and foremost, to question the link joining the technological transformation process and the socio-economic re-composition issues to the challenges related to forms, structures and the dynamics of local development. This link is undoubtedly a powerful maneuver generating economic balance, social and cultural cohesion; as essential conditions for a sustainable city. 

Finally, going beyond the established compromise to achieve the priority of planning the local development dynamics in a sustainable way. It would not be the primary need to promote in long term the upgrading of all public and private initiatives under a strategy of support toward the requirements of the sustainable city, aiming to maintain the issues of dialogue between the actors of the city and their participation in the design, but also in the implementation of local development.
