In Brazil, forests are rapidly being destroyed, slums are expanding, and crime has reached an all-time high.

The solution? Government officials in Rio de Janeiro insist that building a nine mile, cinder-block wall around their slums will help to prevent the Atlantic rain forest from further deforestation, and restrict the expansion of these shanty towns. Human rights groups and many residents of the slums — known as favelas — disagree, reports the Wall Street Journal. They claim the purpose of the walls is to further separate the slums from Rio's beautiful beaches and wealthier residents.

To give the government's claims some credit, the expansion of favelas has contributed to Rio De Janeiro's rain forest destruction over the years. In 2004, deforestation reached its peak when 10,588 square miles of forest were destroyed. The Atlantic rain forest, an ecosystem that once was a large and flourishing part of Brazil, has lost 93 percent of its forest cover. The walls are meant to serve as "ecobarriers," to prevent the favelas from expanding into the already at-risk, forested hillsides.

But it seems that the reason for the wall stems beyond the goal to protect the rain forest. The Journal explains:

it's all part of a wider plan by Rio officials to clean up the famously freewheeling city. Under Mr. Cabral, the state intends to hire 22,000 police officers in part to occupy favelas now under control of drug gangs.

Residents of Rio's slums claim the wall will only cage them in and restrict their ability to come and go as they please. Human rights groups are up in arms as well — referring to the proposed wall as a means of "social apartheid."

Representatives of Rochina, one of the many Rio slums in, convinced government officials to replace the high wall with ecological parks, paths, and low walls that still mark the limits of the neighborhood. Other favelas are are trying to follow suit and some government officials are reportedly considering alternatives to the wall. In the meantime, the construction of the walls continue until perhaps a different idea is agreed upon that makes the barrier clear without making residents feel trapped.

Even UN Secretary-General Ban Ki-moon was surprised by the large number of people who greeted him in Kibera, the largest slum in Nairobi, Kenya. But his surprise quickly became concern when he was told so many young people came to see him because they couldn't find work.

Inspired to act, Ban donated $100,000 of his own money to a UN-sponsored program that helps unemployed youth acquire vocational skills like carpentry, masonry, electrical wiring, plumbing and management. It's called the Youth Empowerment Program (YEP).

Students learn their trade through hands-on activities as they build a training facility that will allow YEP to expand its participant ranks. After graduation, many of the youth are placed in jobs or apprenticeships with private companies or UN-sponsored construction projects in Kibera.

The training program is part of a greater state- and UN-sponsored initiative to upgrade services and infrastructure in Nairobi's slums. Youth skills training also complements another UN-funded effort, the Urban Entrepreneurship Program, that helps to establish construction collectives and aid them in bidding on contracts.

Linus Sijenji, a youth coordinator in Kibera, notes that the combined efforts of the two programs are inspiring the youth and have opened up opportunities for them.

Our aim is to form our own companies that could competitively bid for such contracts on equal level with big companies. Much as this might seem far fetched, the idea is viable, especially with more training opportunities and resources like bank loans.

If these programs work as advertised, Ban will get an even bigger reception next time he comes to Kibera.

Even before it cashed in on eight Oscars, Slumdog Millionaire had sparked a global conversation around the film's depiction of slum life in India.

Critics say Slumdog's dramatized images of destitution, squalor and prostitution send a distorted message to audiences. It also overlooks the resilience of India’s hardworking slum-dwellers, Gautaman Bhaskaran writes in the Japan Times:

Is this not what the developed West wants to see of India: its underbelly of crime, corruption and poverty that appears all black, dark and depressing, with little gray or goodness?

Meanwhile, economist Howard Husock draws a more hopeful message from the film: that slum life is not, in all cases, inescapable.

By finding a hero who rises from shacks and degradation, the film reflects a surprising new consensus that even as slums proliferate around the world at a greater scale than ever before, they could, with the right mix of policies, be the launching pads for upward mobility rather than dead-ends.

Over the last half-century, slums around the world have been transformed from temporary settlements into thriving urban centers, Husock writes in Forbes. In Mumbai’s Dharavi slum (where Slumdog was shot), small businesses are multiplying at a staggering rate.

But residents in Dharavi, Asia’s largest slum, are less concerned about entrepreneurship and infrastructure than they are about a redevelopment project that would demolish their community. A plan to convert shanties into upscale apartments and office towers would uproot Dharavi residents from homes where they’ve lived for years — in some cases, for generations.

"This city has always been about diversity of habitats," urban planner and activist Rahul Srivastava told India’s Economic Times. "We have low-rises and high-rises, villages and slums. Why can't we make slums acceptable living spaces?"
