What is it about?

To have modern cities, governments of developing countries are obliged either to destruct or to upgrade spontaneous housing areas. We set up a slum-upgrading strategy that guides decision-maker on the profitability of the operation.

Why is it important?

Our strategy focuses on seven technical criteria of slum upgrading, based on UN standards. We take into account the profile of the target population to see what proportion should be relocated on site, who should pay and which amount. Knowing that Government grant should complete the funding deficit, we calculate the profitability and return on investment period. All that data are necessary criteria that guides decision makers on what to do. It's a more appropriate for developing countries who have limited financial ressources.


The application of the strategy is quite tedious. According to the similarities of slums, we plan to integrate automated systems relying on IA to propose the best upgrading scenarios to decision maker.
