The UN Habitat defined slums as “a group of individuals living under the same roof in an urban area who lack one or more of the following:
1. Permanent, long-term housing that protects against adverse climate conditions,
2. Adequate habitual area for multiple people in the same house,
3. Unchallenging and safe access to water.
Slums and Living Challenges in Urban Areas:
Whereas urbanisation has been an instrument of economic, social and political progress, it has led to serious socio-economic problems. The sheer magnitude of the urban population, haphazard and unplanned growth of urban areas, and a desperate lack of infrastructure are the main causes of such a situation. The rapid growth of urban population both natural and through migration, has put heavy pressure on public utilities like housing, sanitation, transport, water, electricity, health, education and so on.
Urban sprawl or real expansion of the cities, both in population and geographical area, of rapidly growing cities is the root cause of urban problems. In most cities the economic base is incapable of dealing with the problems created by their excessive size. Massive immigration from rural areas as well as from small towns into big cities has taken place almost consistently; thereby adding to the size of cities. Overcrowding is a logical consequence of over-population in urban areas. It is naturally expected that cities having a large size of population squeezed in a small space must suffer from overcrowding. This is well exhibited by almost all the big cities of India. Overcrowding leads to a chronic problem of shortage of houses in urban areas. This problem is specifically morae acute in those urban areas where there is large influx of unemployed or underemployed immigrants who have no place to live in when they enter cities/towns from the surrounding areas.
For about a third of urban Indian families, a house does not include a kitchen, a bathroom, a toilet—and in many cases there is no power and water supply. Only 79 per cent (42.6 million) urban household live in permanent (pucca) houses. 67 per cent (36 million) of the urban houses are owned by the households while 29 per cent (15 million) are rented. The natural sequel of unchecked, unplanned and haphazard growth of urban areas is the growth and spread of slums and squatter settlements which present a striking feature in the ecological structure of Indian cities, especially of metropolitan centres. The rapid urbanisation in conjunction with industrialisation has resulted in the growth of slums. The proliferation of slums occurs due to many factors, such as, the shortage of developed land for housing, the high prices of land beyond the reach of urban poor, a large influx of rural migrants to the cities in search of jobs etc.
Socially, slums tend to be isolated from the rest of the urban society and exhibit pathological social symptoms (drug abuse, alcoholism, crime, vandalism and other deviant behaviour). The lack of integration of slum inhabitants into urban life reflects both, the lack of ability and cultural barriers. Thus the slums are not just huts and dilapidated buildings but are occupied by people with complexities of social-networks, sharp socio-economic stratification, dualistic group and segregated spatial structures.
