Urban catalysis is the term given to the series of projects geared towards urban development. Increasing urban areas encourages stimulation of economic activity via commercial enterprise; therefore it is responsible for the establishment of the major cities of the world. Despite the benefits of urbanization, there are also many adverse effects.

Adverse effects of urbanization.

Slums also known as informal settlements are areas of densely populated villages usually around the city area. They are characterized by poorly constructed houses (galvanize, plastic, pieces of boards) shanty towns and squalor. Sea lots in northern Trinidad is an example of a slum area. Bordered by the busyness of the capital on the east, and the unpredictable waters of the gulf to the west, the slum exists just as any other settlement in Trinidad and Tobago. As one passes this area to enter the capital, litters can be seen strewn throughout the street connecting to the rest of the capital; graffiti decorates the walls of unpainted, mold covered walls of buildings aged with weather. Signs of dilapidation, poverty and neglect are visible to the naked eye.
