Urban Issues

All cities are divided between rich and poor sectors. Business growth and rising numbers of tourists increase the incomes of the rich but the poor see little of the increased wealth. Vast numbers live in shanty towns in cheap, self-made sheds. There is insufficient clean water or sanitation, few schools, few amenities of any kind. Health suffers first. It is estimated that 100 million people in cities are homeless in both developed and developing countries. Some of the worst polluting industries are likely to be located in poor or racially distinct neighbourhood.

Water

Water is the single most valuable resource for cities. Many cities are facing a serious shortage of safe drinking water as a result of leaking pipes and pollution from POPs. Most city people in developing countries end up boiling their water, or buying bottles. Where piped fresh water is available, it usually only goes to elite residential areas. The poor still have to buy their water through middle men and end up

Many people want to live in cities – but they should remember as they pass through the city gates that, inside, the reality is often squalor, violent crime, dingy high-rise blocks of flats and open sewers.

World population grows at 215,000 a day. In 1999, we reached six billion people. By 2050, there will be many billions more. We’d need to build a city the size of Lima (Peru) every 20 days to house them. Instead, we will expand and merge existing cities, creating mega-cities. Mexico City has grown from 12 to 18 million in 30 years. Jakarta grew 8 million in just 15 years. China’s urban population grew from 192 million to 375 million in 16 years. Cities seem destined to just go on growing and growing!

City Waste

Very few cities in developing countries have proper facilities for disposing of solid and human waste. Because cities generate so much of both, this is a huge problem to people’s health and the pleasure of living in a city. At the municipal dump of the city of Guaiba, in Brazil, there are people who make a living from sorting the waste. It might seem impossible that people can survive on waste. But of the 40,000 kg of waste thrown away each day in Guaiba alone, 70% could be recycled. Twenty per cent could be used as compost. So, if it was properly sorted, only 10% of the waste would end up in the dustbin.
