Urban activities generate large quantities of city wastes including several Biodegradable materials (like vegetables, animal wastes, papers, wooden pieces, carcasses, plant twigs, leaves, cloth wastes as well as sweepings) and many non-biodegradable materials (such as plastic bags, plastic bottles, plastic wastes, glass bottles, glass pieces, stone / cement pieces). On a rough estimate Indian cities are producing solid city wastes to the tune of 50,000 - 80,000 metric tons every day. If left uncollected and decomposed, they are a cause of several problems such as
Causing serious drainage problems including the burst / leakage of drainage lines leading to health problems.
- barrier to movement of water
Solid wastes have seriously damaged the normal movement of water thus creating problem of inundation, damage to foundation of buildings as well as public health hazards.
- foul smell - generated by dumping the wastes at a place.
- increased microbial activities
Microbial decomposition of organic wastes generate large quantities of methane besides many chemicals to pollute the soil and water flowing on its surface
- When such solid wastes are hospital wastes they create many health problems - as they may have dangerous pathogen within them besides dangerous medicines, injections.
Pollution of Underground SoilBack to Top
Underground soil in cities is likely to be polluted by
- Chemicals released by industrial wastes and industrial wastes
- Decomposed and partially decomposed materials of sanitary wastes
Many dangerous chemicals like cadmium, chromium, lead, arsenic, selenium products are likely to be deposited in underground soil. Similarly underground soil polluted by sanitary wastes generate many harmful chemicals.These can damage the normal activities and ecological balance in the underground soil.
Essay The Implications of Rapid Urbanization
1685 Words7 Pages
Urbanization is the process of human migration from rural areas to towns and cities, thus rapid urbanization means that the rate at which the migration from rural to urban takes place is hurried that a country has no time to plan for their existence at the cities. The situation differs from country to country as the number of cities and rural areas in the countries are different. Another possible reason for the difference is the development nature of the countries; some countries are developed, others are developing while others are considered least developed. Urbanization in developed areas can be traced from the industrialization era when the populace migrated from the rural/ancestral home to towns in search of employment.…show more content…
They abandoned farming and moved to the urban areas making the Mexico City to be among the top largest cities with rapid urbanization. Urbanization and especially the Rapid ones come with implications; both positive and negative. Other countries especially developing and less developed are not well prepared for the growth in population at the cities thus causing a strain on the available resources. Global negative implications are increase in traffic, environmental pollution, overcrowding among public institutions and facilities and increase in the cost of life at the cities (University of Michigan, 2006).
A common problem among African cities is the poor hygienic conditions that have been brought by the rapid urbanization. From Nairobi in Kenya to Lagos in Nigeria and Windhoek in Namibia, rapid urbanization has led to the debilitating environment; vast slum dwellings, inadequate water supplies, poor garbage disposal, poor drainage systems and poor medical services. This in turn has bred what is known as vectors and reservoirs of communicable diseases such as malaria, lymphatic diseases, HIV/AIDS, typhus and yellow fever (Potsiou, 2010). As urbanization rate grows, so is the population growth within the cities from new births and this
