Improving Slums

We had a debate in our geography class last year about which issues were most important to resolve when upgrading slums. We were each assigned a particular aspect of the worst-case situation to argue as a priority to resolve, and asked to come up with some means to solve it. That’s why this might come off as very poorly structured (even by my standards). I’m also mentioning that explanation as I’m not sure where my notes on healthcare measures went, and this is likely to be updated once I’ve found (or remade) them.

Physical Infrastructure

  • 84% of houses have no water supply. Illegal water sellers are expensive, and many people take water from rivers.
  • Roads are impermeable (leading to issues with erosion, flooding downstream and others)
  • Illegal electricity (in many slums) can lead to electrical fires
  • 90% of people in slums (worldwide) die of disease
  • Water can be purified using plastic bottles
  • Kenya has projects for community based solar power to help improve the local electrical supply
  • The Green Exchange program (where waste is exchanged for cash or food parcels. The waste is used for various purposes depending on location. In Curitiba, Brazil, it is reused for other purposes. The exact waste can vary with location, too. It helps prevent malnutrition and any issues that could arise from a dirty environment.)

Social Infrastructure (mostly referring to Rio de Janeiro)

  • 880 million people live in slums globally.
  • Complexo de Alemão is trying to reduce crime rates by building 2 primary schools, 2 creches, a technical college and a library
  • Complexo has 70,000 people with insufficient education and healthcare
  • A cable car was built to transport people from the slums to Rio’ center. This has helped unemployment rates. The stations are cheap, and have lead to greater educational, job, and healthcare options.
  • Cidade de Deus healthcare clinic was set up in the slums
  • Olympic values were taught to children; 168 schools, 100,000 children
  • Favela painting is a practice to occupy people’s time productively. The favelas are made to look better by occupying local people to paint buildings in bright colours and patterns. The normal buildings are often bare brick and mud. Very drab environments are bad for people’s emotional health, so painting the favelas in bright shades is improving people’s wellbeing.
  • There has been an 80% drop from 30,000 gun crimes per year once gangs were removed.

Housing

  • 40% live in shanty towns
  • People used to just be used to worse areas
  • Now people are provided with material
  • There are housing projects to remove the shanty areas and replace them with proper housing
  • 1/3 of people in poor cities live in self-built houses
  • The Bairro project, in Rociña, Rio de Janeiro, aims to increase the average size of slum homes to 20m^2 and to widen the main streets.
  • Barra de Tijica, Brazil, is a new town located through a mountain from Rio, providing new housing in 10-30 storey blocks, and is now home to 180,000 people.
  • Almost all the houses in Rociña are made out of concrete and brick, contributing to 100s of businesses
  • NGOs are working to improve the situation
  • Oxfam are working to improve the lives of 100 million people living in slums worldwide
  • Some slums still have no provision of basic services.

Employment

  • Oxfam provides water tanks for affordable use in many slums
  • Most people use informal water supplies
  • in Hima, Peru, there was a census including types of businesses, which lead to improvements in encouraging foreign businesses to buy goods from slum workers.
  • Does this actually provide them with enough money to escape poverty?
  • People in slums can enter themselves in the yellow pages, which has been quite successful in Brazil and Peru.
  • However, businesses in slums are unregulated by the police, and are unprotected by the police, in many areas

Waste

  • 4.3 million cases of cholera worldwide
  • Most people produce about 300g of waste a day
  • 2.4 million people in Nairobi are living in slums
  • Composite farms gather waste in biodegradable bags, which, after 6-8 weeks, can be used as manure, leading to better soil fertility, better farming, and more food and income
  • Bioplants can be made in Kibera. Many people use the same latrine. The methane produced from this can be harvested and then resold as cooking gas, which helps kill off germs in water and food
  • Umende has 57 bio centers, and has collected 60,000 kg of waste
  • Nepal has 2.8 million people living in slums. In Kathmandu. 10,000 of the 31,000 slum dwellers are waste collectors. The informal sector work is often exploited.
  • There is an Umbrella Group which workers can register with t monitor them and give vocational training
  • The Green Exchange program in Nepal has led to 4,000 waste worker jobs, with 50% of the beneficiaries being women.
