With a population of 100,000 people, the Complexo do Alemao favela is one of the largest in the Brazilian city.
It stretches more than two miles February 3 km, a maze of narrow alleys and stairs.

Operational since July of last year, the cableway do Alemao cable car system is the most obvious example outward of how people's lives in Complexo do Alemao have been transformed by a city policy to scale called pacification.

In the case of Complexo do Alemao, 300 police and soldiers went to the end of 2010, with tanks and helicopters They offered little resistance, as the gang members chose to flee rather than fight.
With secure shanty town, the staff of the Municipal Authority of Rio could start to go safely to ensure the second part of the pacification program - social services such as schools, health care centers, and collecting garbage.
The decision was taken by the government of the wider state of Rio de Janeiro to build a cable car system to allow residents to move much more quickly was chosen instead of roads or railway system, because the favela is so dense with houses it was the least disruptive option.
The cable cars allow residents to move from one end of the favela to the other in just 16 minutes walk, it would take two hours, and every local person receives a free return ticket every day.
The system also connects to the rail network in Rio, which allows residents of Complexo do Alemao to quickly get into the city center, and thus better able to get jobs in the real economy.

By improving the social conditions of the favelas released control of drug gangs, the goal is both to better help their economies, and resident employment prospects.
Ms. LaRocque said that one of the main results of the pacification program is that pacified favelas are added to the official Rio cards.
This is something very important A young man who is looking for work in the larger city, it wouldn t have had a zip code in the slums, so we introducing them to the official map of the city.
In addition, we try to provide many training courses to prepare young people access to good jobs, and there are many new companies that appear in the favelas themselves as new opportunities.
But what do the people who live in the favelas think pacification schemes.

Natalaia Barros, 19, a housewife, said the good point is that we hardly hear gunshots.
Things are cleaner, there are more shops, there are more things for kids to do.
We can stay outside, there are no bandits, gang fights and so on.

We could sleep with the doors open and no one in your home today, everyone is afraid of being robbed in the community and many will now fly.

Indeed, in a sense, the UPP pacification plan opens the economies of the favelas to the outside world, and before, they were dominated by drug gangs.
Rio in general, says Professor Neri, the program is of great value because it increases the wealth of the wider city, especially as a reduction of crime makes them less suspicious tourists to visit.
People will not just come over Rio, but also the favelas become a tourist attraction themselves, he said.
However, Professor Neri said the biggest problem of the peace plan is how the Rio economy can offer more jobs to many young people in the favelas now get a better education.
Young people are the greatest challenges of peacekeeping, how to offer opportunities to young people, I think it is a very difficult challenge, he said.

You can see him do these desirable communities for those living in them haven t, young, adventurous.

However, he said that the main concern is the drug gangs have simply been moved to the pacified favelas yet, or just outside the city of Rio.
I think this is true, as there is still demand for drugs, but moving is costly for them.
