Abstract: The unplanned neighbourhood of Macuti, in Mozambique, experiences extended and prolonged flooding for half of the year during the wet season. Although cyclones and extreme weather events often hit the city, the lack of basic infrastructure and, above all, of a widespread drainage system makes the settlement particularly vulnerable to even minor events. In addition, the flat area is altimetrically prone to rainwater accumulation and the clay soil hinders infiltration. These peculiarities delineate an interesting case study that has been the focus of an international cooperation project, designed with a potentially replicable methodology in other similar cases worldwide. The project methodology integrates social surveys, hydraulic and hydrologic modelling, a participatory process among the key stakeholders and spatial multicriteria analysis. This has allowed to choose an optimal and agreed pilot solution for urban drainage in the specific unplanned neighbourhood, which also fits the principles set by a neighbourhood-scale urban plan proposed within the same project. The chosen solution can be viewed as an experimental pilot able to meet both the hydraulic and social needs of a space claimed by the community in the framework of a fast-growing environment.
