Abstract

Algiers port and city’s exceptional history is driven by its remarkable site nestled on a rocky spur. Yet this morphology constrained the urban growth of a city that could pretend joigning the ranks of large metropolis .During its history port and city relationship took multiple forms, frequently compatible yet sometimes divergent and even opposed, leading to inversing domination status of both actors. Algiers capital of a 40 million inhabitants state, has always been a laboratory of urban politics since the colonial era to the institutional constructions of independent Algeria, regardless of deficient statistical tools.  However, the space in Algiers is confronted to great challenges due to an anarchic growth of its population, fragmented urban spaces and unbearable motion constraints.  If road and collective transportation infrastructures are growingly programed and achieved by successive plans, their articulation with built-up areas and housing developments with the aim of eradicating slums does not seem to be really coherent.  Furthermore, the location of communal amenities which seem to be relating to real estate opportunities, adds to the complexity of the urban fabric.  However, under this apparent complexity, arise deep urban logics that should be highlighted and modeled.

Abstract

Urban development can take different forms or features, depending on its geographical location and its socioeconomic, political and cultural context. Nevertheless, the overall action relies on one fundamental principle: building construction in order to give people housing. Therefore, the main objective of this research is to determine whether an underlying universal aspect of the urban development process can be distinguished from a specific one, being the reflect of local specificities. Specifically, this research analyzes the land use change on the French-German cross-border area. Indeed, the border context enhances the difference within this territory. Nonetheless, the internal European border importance as a separation is getting lower while European Union agreement and cooperation are getting stronger. Consequently, we tend to question a potential homogeneity of such area according the urban development analysis. To gain a better understanding of the urban development in the French-German cross-border area, a specific method using a decision tree (DT) process to generate and calibrate urban transition rules for cellular automata (CA) has been developed. In order to define CA rules, the learning algorithm is provided with data of land use, from 1990 and 2006, accessibility to the main urban area and country location. The findings demonstrate that the rule set identified rules, which are constrained at different levels: from the initial land use state needed for urbanization to the geographical location in a specific country. The analysis therefore shows rules specific to France or Germany, as well as rules free from any state location constraints, which characterize a cross-border urbanization process. The latter is more influenced by the location toward main urban areas. Proper neighborhood and internal characteristic of urbanized cells depending of the nature of the rule (French, German or Cross-border) are explicitly defined. In conclusion, this research contribution can be summarized according to the following three orientations: (1) from a theoretical point of view, which propose to identify urban processes degree of universality, (2) from a thematic outlook, describing the influence of the urban development process location on the border area, (3) from a methodological point of view, pairing DT and AC to automatically design and calibrate the urban development model used in this research work.

Geography has since antiquity used cartography to describe the shape of the Earth and its population. Indeed, cartography is an analogical model of the world particularly suited to the description of shapes, spatial arrangements and spatial relationships, i.e. information of a qualitative nature, the meaning of which emerges when reading maps. The theoretical and quantitative turn in geography has seen the development of many formal and numerical modelling approaches in which, paradoxically, it is more difficult to integrate the question of the meaning of space in human activities. In this work, I propose a formal modelling framework aimed at clarifying the meaning of space. Through a phenomenological approach, I identify the different forms of perception of individuals and human communities, in order to propose general principles that are then mathematized by techniques from the sciences of complexity. Three models related to urban morphogenesis illustrate different facets of this general modelling framework aimed at giving meaning to space.
