Medellin, Columbia

- A giant outdoor escalator has been built in the favela- cost $7m (£4.5m) - Previously had to climb hundreds of steps to get home from the city centre - this was not an option for the elderly, pregnant women etc - About 12,000 residents of Comuna 13 will benefit from the escalator, which is free to use and shortens a half-hour walk to about five minutes - Has given many people the independence to travel around the slum and to get the CBD to work - It has improved their sense of community

Rio de Janeiro - Favelas

- According to the 2010 Census, about 6% of Brazil's population live in favelas or shanty-towns - around 11.25 million people across the country - However, there could be even more living in these communities - Rocinha is Brazil's largest favela and unofficial estimates say it has up to 180,000, compared to the census figure of just 70,000 Positives: - Favelas have thriving communities, with a whole range of employment, people and facilities - Sense of community - Some businesses thrive and people are able to make a life for themselves Negatives: - There are great disparties within the favelas, and between people from favelas and from other parts of Rio - High class residential areas are found next to the CBD and along beaches of areas such as Copacabana. Apartments are very exclusive and cater for the wealthy workers of the CBD- many of these high rise apartments have 24 hour security and armed guards - More than 1.2 million people live in the favelas on less than £1 per day - High incidences of malnutrition, diarrhoea and other diseases - High crime rates and gang violence - Lack access to the most basic public services, such as health care, education, and space for recreation -Infant mortality rates are high in favelas- 50 per 1000 compared to a national rate of 15 per 1000 Solutions: 1. Site and service schemes - These give people the chance to rent or buy a piece of land that is connected to the city by transport links and has access to essential services such as running water - People build their own homes using money from a low-interest loan 2. Self help schemes - People are given tools and training to improve their homes - Low-interest loans may be used to help people fund these changes - People may be given legal ownership of the land they live on 3. Rural Investment - Improving the quality of life and creating greater opportunities in rural areas may prevent people from migrating to urban areas

Tokyo's ecological footprint

- According to the Earth Council, a biologically productive area of 1.7 hectares is needed per person for basic living - For Tokyo, they would need 1.2 times the area of Japan for each person to have this amount of land Working towards sustainability: - A mandatory program for 1,400 of the area's factories and office buildings to cut their carbon emissions 25% from 2000 levels by the end of 2020 - Toughened environmental building standards - Cash incentives for residents to install solar panels - A plan for greening the city, including planting half a million trees and converting a 217-acre landfill in Tokyo Bay into a wooded "sea forest" park

London - Ethnic segregation

- Between 1960 and 1980, the white population of London relocated to the suburbs - Housing left behind was then occupied by immigrant populations - eg.

- Congestion charges were introduced into central London in February 2003 - There is an £8 daily charge for driving or parking a vehicle on public roads within the congestion zone between 7am and 6pm on Mondays to Fridays - The original congestion zone covered 22km2, but was extended by 50% in 2007 - Cameras at the entrance point of the zone automatically capture the number plates of vehicles in the zone and a penalty of £100 is given to those who do not pay the charge - Some vehicle types are exempt- e.g. buses, taxis and motorcycles, and some can apply for a reduced price eg. disabled people Impacts: Traffic levels in the zone have been cut by 20% Congestion has been reduced by around 30% during the time frame There has been an 82% increase in cycle trips There has been a net reduction of between 40-70 road traffic casualties per year

Paris Heatwave 2003

- In 2003, a persistent anticyclone over Europe caused a heatwave with consistent temperatures of over 40 degrees recorded in some areas - 30,000 people in Europe we killed - Paris maintained temperatures of over 38 degrees for nine consecutive days - The heat caused extreme dehydration and cardiovascular illnesses - Those most afflicted were the elderly - Paris in particular had a high population of elderly women living alone who could not cope with the heat Responses: - A debate about how France deals with its elderly care led to the development of a heatwave plan of action - this includes local government, the health sector, humanitarian organisations etc - The elderly and handicapped people were encouraged to become more involved in the community - A phone help line was set up and alerts and cool shelters were set up for future heatwaves - A subsequent heatwave in Paris in 2006, where temperatures reached over 40 degrees killed only 42 people - The plan does not address the long term problem of overheating in cities

Australia - Inequalities

- Inequalities between indigenous and non-indigenous Australians - Indigenous people have: - shorter life expectancy - higher rates of infant mortality - poorer health - lower levels of education and employment - This is due to racial descrimination, lack of education and employment etc - In 2016, Indigenous children experienced 1.7 times higher levels of malnutrition than non-Indigenous children - There is over a decade difference in life expectancy - around 70 for indigenous and around 80 for non-indigenous - In 2016, Indigenous children experienced 1.7 times higher levels of malnutrition than non-Indigenous children - Median weekly income for Indigenous Australians was $542 in 2014-15 compared with $852 for non-Indigenous Australians - In 2008, the Australian government made a formal commitment to address Indigenous disadvantage in Australia, known as 'Closing the Gap' - The Closing the Gap strategy has made some improvements to Indigenous health since it was introduced in 2008. Sadly, all except one of the seven Close the Gap targets were behind target in 2016
