Solar panels shine on the rooftop terraces of 10 neat buildings with perfectly straight lines and of uniform height, an image of modernity that contrasts with the precariously-built dwellings with unplastered concrete block walls just a few metres away, with rooms added in a disorderly manner, surrounded by a tangle of electric cables.
"We are the people who are excluded from the system," says Rafael Rivero, sitting in his apartment in a new social housing complex next to one of the largest slums in Buenos Aires. The contrast sums up the complexity of the social reality in the Argentine capital.
Between the dimly-lit, narrow alleyways of Villa 21, only 30 minutes by bus from the centre of the Argentine capital, more than 50,000 people live in poverty.

Pink, green, blue, red. From a distance, the thousands of brightly coloured houses look like a painting.
