Abstract
One of the greatest changes that have occurred in the last century in developing countries is the urban growths which have produced more slums in our cities. The study examines the physical conditions in Makoko, an urban slum in Lagos, Nigeria. Geographical information system (GIS) and remote sensing (RS) technologies were used, in a post classification, to model possible land use changes in the area overtime. It also uses questionnaires to elicit information on infrastructural and socio-economic characteristics to determine the factors responsible for the physical conditions of Makoko. Findings revealed that the rate of infrastructural provisions are lacking behind and suffer from overstress and dilapidation The residents lack good environmental sanitation as the lagoon emits a pungent smell. It is recommended that the area is entirely restructured so as to create a habitable abode for sustainable residential living. Key words: Slum, urban growth, physical condition, environmental sanitation, GIS/RS and Makoko.
Highlights
One of the most remarkable developments in the world especially since the 1980s is rapid urbanization
Today, according to UNDESA (2015), “fifty-four percent (54%) of the world‟s population lives in urban areas, a proportion that is expected to increase to 66% by 2050”
Projections show that urbanization combined with the overall growth of the world‟s population could add another 2.5 billion people to urban populations by 2050, with close to 90% of the increase concentrated in Asia and Africa (UNDESA, 2015)
Summary
One of the most remarkable developments in the world especially since the 1980s is rapid urbanization. Today, according to UNDESA (2015), “fifty-four percent (54%) of the world‟s population lives in urban areas, a proportion that is expected to increase to 66% by 2050”. Projections show that urbanization combined with the overall growth of the world‟s population could add another 2.5 billion people to urban populations by 2050, with close to 90% of the increase concentrated in Asia and Africa (UNDESA, 2015). According to George (2002), “an average of 6,000 people move to Lagos everyday and the United Nation has estimated that the city of Lagos will swell to 25 million by 2016”. The consequence of this is unabated gross degradation and decay of all the constituent fabrics of the city
