A shanty town or squatter area is a settlement of improvised buildings known as shanties or shacks, typically made of materials such as mud and wood. A typical shanty town is squatted and in the beginning lacks adequate infrastructure, including proper sanitation, safe water supply, electricity and street drainage. Over time, shanty towns can develop their infrastructure and even change into middle class neighbourhoods. They can be small informal settlements or they can house millions of people. The term 'shanty' is likely derived from Canadian French 'chantier' (low-level workers' quarters), or alternatively from Scottish Gaelic; "sean" (pronounced: shen) meaning 'old' and "taigh" meaning 'house[hold]'. Globally, some of the largest shanty towns are Ciudad Neza in Mexico, Orangi in Pakistan and Dharavi in India. They are known by various names in different places, such as favela in Brazil, villa miseria in Argentina and gecekondu in Turkey. Shanty towns are mostly found in developing nations, but also in the cities of developed nations, such as Athens, Los Angeles, and Madrid. Cañada Real is considered the largest informal settlement in Europe, and Skid Row is an infamous shanty town in Los Angeles. Shanty towns are sometimes found on places such as railway sidings, swampland or disputed building projects. Construction Shanty towns tend to begin as improvised shelters on squatted land. People build shacks from whatever materials are easy to acquire, for example wood or mud. There are no facilities such as electricity, gas, sewage or running water. The squatters choose areas such as railway sidings, preservation areas or disputed building projects. Swiss journalist Georg Gerster has noted (with specific reference to the invasões of Brasilia) that "squatter settlements [as opposed to slums], despite their unattractive building materials, may also be places of hope, scenes of a counter-culture, with an encouraging potential for change and a strong upward impetus". Stewart Brand has observed that shanty towns are green, with people recycling as much as possible and tending to travel by foot, bicycle, rickshaw or shared taxi, though this is mainly due to the generally poor economic situation found. Development While most shanty towns begin as precarious establishments haphazardly thrown together without basic social and civil services, over time, some have undergone a certain amount of development. Often the residents themselves are responsible for the major improvements. Community organizations sometimes working alongside NGOs, private companies, and the government, set up connections to the municipal water
