Abstract:

According to a United Nations report, the proportion of the urban population living in informal houses worldwide had reached 23.5% in 2018, which means over 1 billion people have been living in slums, and an estimated 3 billion people will be requiring affordable housing by 2030. Slums are often linked to developing countries, where weak governance and misled socio-economic choices aggravate the situation and lead to continual conflict with the authorities. This research aims to model this conflict through Game Theory and shed the light on the different parameters that influence the decision-making process and finally propose a management model to limit the spread of this phenomenon as much as possible. This model will be applied in the city of Hassi Bahbah using ABM, the results of the game modeling allowed us to extract the delta threshold which will allow decision-makers to know when they have to make decisions. Our study aims to offer decision-makers a tool based on our model, allowing them to better manage and thus monitor the evolution of informal houses. The authors hope that the findings could provide means and insights for policies and strategic directions in land uses and planning systems.
